模块的这个特点通过其传感器连接件实现，初始时连接件处于竖直的位置，当顶板受到水平冲击力时，连接件会偏离原先的位置，连接件的独特设计会使之产生一回复力，回复到原来的位置，保持竖直。

当秤台受到水平冲击力时，顶板上的限位螺栓顶住传感器，限制其相对与顶板的大幅度移动。

连接件的回复力使载荷垂直作用于传感器，并且回复力随着秤台承载的增加而增大。

1.4 MTCN称重模块的特点MTCN称重模块一个突出的特点在于其简单合理的设计，没用需要焊接的部件，也不需要额外的配件，所有模块的制造、组装、测试都符合ISO9001质量标准和ISO14001环境标准，这将保证您方便、快速地进行安装且调试工作很少。

MTCN称重模块能在形状各异的物体上安装，从而节省了大量的时间和精力。

传统的电子称重系统，在进行静态载荷或动态载荷称重时，很容易受到周围环境的干扰。

影响系统称量准确性的因素很多，一些出于系统本身，如系统的设计、安装、标定及维护；另一些是外部因素，如上升气流、震动、温度的变化及地震等。

Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.ModelsOverviewThe PVD Series Parts Verification Sensor is a one-component, easy-to-use light screen suited to many part assembly, bin picking (pick-to-light), and error-proofing applications. The PVD increases task efficiency due to simplified job training, increased quality control (no skipped components), and reduced rework and inspections. It speeds the resumption of work after breaks and other distractions, and is ideal for multilingual workplaces where communication is an issue.The PVD self-contained, solid-state emitter/receiver array is capable of functioning in either diffuse or retroreflective sensing mode. Noconfiguration is required for this selection. If a retroreflective target is installed opposite the sensor, it will function in retroreflective mode. If not, it will function in diffuse mode. The sensor’s ongoing self-adjustment feature requires no user adjustment; the sensor adapts to the sensing conditions after 15 seconds when blocked. Sensor range decreases when no retroreflector is installed.The DIP-switch-selectable PNP/NPN output interfaces to a system controller, which is pre-programmed for a specific sequence of tasks.Mounted with its visible red beams stretching across each parts bin, the sensor job light signals the assembler which bins contain items to be picked in a given operation and in what order they should be picked.As the assembler takes a part in sequence and breaks the beam, the sensor senses that the part was removed and it sends an output signal to the controller. The controller then verifies if the correct part was taken and may respond by turning that job light OFF, activating the job light of the next bin in the sequence. If the assembler reaches into a bin out of sequence, the PVD turns on its output to signal the system controller and turns on its red job light to signal the assembler that an incorrect pick has occurred.Standard configuration options are selected by means of a bank of four DIP switches behind a press-on black rubber cover. DIP switch options include: PNP or NPN output, Normally Open or Normally Closed operation, steady or flashing job light, and job light control input.•To order the 150 mm (6 in) cable model with a quick disconnect, add the suffix "W/6IN" to the cabled model number. For example,PVD100Q W/6IN.•Models with a quick disconnect require a mating cordset.PVD Series Parts Verification SensorOriginal Document 113230 Rev. G4 August 2016113230Figure 1.

Minimum object detection size (retroreflective operation)InstallationMultiple sensors located farther than the sensor's maximum range from one another are unlikely to cause crosstalk problems. However, when multiple sensors are mounted in a confined area, take care to avoid crosstalk between them. Alternate the relative position of adjacent sensors and/or reflectors. Sensors positioned above or below one another should not create crosstalk difficulties. Mount the sensor and reflector parallel.Figure 3. Examples of Appropriate Positions Figure 4. Example of Incorrect Position - Tel: +1-763-544-3164P/N 113230 Rev. GMountingThe wide beam pattern of PVD sensors simplifies their alignment. M4 stainless steel fasteners and two stainless steel brackets are included with each sensor.Mount the sensor and its reflector, if used, parallel to one another in the same plane, and their tops and bottoms aligned.1.From a common point of reference, make measurements to locate the sensor and itsreflector, if used, in the same plane with their midpoints directly opposite each other.2.Mount the included brackets to the top and bottom of each sensor, as shown.3.Mount the sensor in its brackets and the reflector, if used, being careful to position thesensor's red lenses directly facing the reflector.4.Measure from one or more reference planes (for example, the building or bin floor) to thesame point(s) on the emitter and receiver to verify their mechanical alignment. (If the sensors/reflectors are mounted exactly vertical or horizontal, a carpenter’s level may be helpful. A straightedge or a string extended between the sensor and the bin wall may also be helpful.)5.Also check “by eye” for line-of-sight alignment.6.Make any necessary final mechanical adjustments, and hand-tighten the bracket hardware.7.After the electrical hookup is complete, check for beam alignment. If necessary, re-align theemitter and receiver at that time.Figure 5. PVD MountingHardwareWiringAll models feature integral 2 m (6.5 ft) long, 3.3 mm (0.13 inch) diameter PVC-jacketed cables. Models whose model numbers end in “Q”are terminated with quick-disconnect (QD) Euro-style 5-pin connectors; other models have unterminated ends. Optional mating QD cables are available.

You can verify by pushing esc until status level is reached and it will display “Setup Incomplete”. If this is the case, re-enter settings menu and use up down arrows to fi nd the parameter with blank fi elds and parameterize as described above. Note: you may enter parameters in any order - eg: Vent min Pos before ZIP Code - If the RTU is a heat pump or uses a 2 speed indoor fan, these paramaters should be enabled fi rst, otherwise the logic may go to Setup Complete prematurely.The ZIP Economizer has built in commissioning processes found in Acceptance Test.1. Economizer Test. Use “Economizer Test” to verify RTU Integrated Economizer operation. Navigate to the “Service and Commissioning” menu, press “OK”; press the down arrow to access “Acceptance Test”. Press OK again when “Economizer Test” appears. Press “OK” again to confi rm running test. Follow prompts during test. This test will open damper to 100%, enable power exhaust fan (if connected), enable 1st stage of Mechanical Cooling, reverse this process and then drive to Vent Min Position. When used with a Belimo actuator, the actuator will speed up to reduce test time.2. Manual Mode is used to override outputs after entering a “Timeout” duration.3. Damper Scaling. The test will re-scale the control signal range to maximum resolution (0...100%) over the calibrated (reduced) angle. When using a Belimo actuator, the actuator will speed up to reduce test time.Note: Failure to identify obstructions or improper setup of damper assembly may result in an improper scaling and operation of the damper.)Additional testing can be found later in this document.1. When all entries have been completed, the ZIP Economizer will switch to Status display and show “Setup Complete”, and will immediately show a “Damper scaling starts in 10secs” and will countdown to 0 (be aware, at 0 the damper will start to move at high speed ). A message will scroll saying “Damper scaling for better operation if obstruction is present rescale damper in commissioning menu”. (For detailed instructions on this – please see the section “Service and Commissioning” below. This will open damper to 100% (re-scale control signal if needed). (Note: failure to identify obstructions or improper setup of damper assembly may result in an improper scaling and operation of the damper.)Once scaling is complete, a message will appear saying “Damper scaling successful”. The ZIP will then show “maximum at80° = 100%” That message will show maximum rotation of the damper. This process ensures the damper is always operating and displayed from 0...100%.2. Once the message has appeared, the actuator immediately closes the damper and a countdown begins, until the unit starts to operate in Automatic Mode (be aware, when countdown complete, the RTU will respond to thermostat calls which may enable mechanical cooling).ZIP EconomizerQuick Setup。

by the increasingly powerful performance of wireless commu-nication and sensing,the technology of Integrated Sensing and Communication (ISAC)has gradually begun to receive attention.On thebasis of hybrid beamforming system for the millimeter Wave (mmWave)Multiple Input Multiple Output (MIMO)technology which hasthe most development potential at present,a beamforming algorithm of ISAC in this

performance of communication and radar,to achieve the optimal solution of the beamforming system for integrated sensingand communication.To overcome the non-convex optimization problem in the process of solving,an alternative optimization algorithm based on coordinate iterative method is proposed.The spectrum efficiency of communication and the beam pattern of radar with differentweight factors

Communication,ISAC)技术,即将无线通信和雷达感知在同一系统中进行联合设计与优化,从而提升资源利用率,降低硬件成本,实现高性能通信和高精度感知[2]㊂通信感知一体化在实现通信传输的同时,还能通过分析无线点的反射㊁散射等特性,对目标信息进行定位和识别[3]㊂通信与感知的融合可以让二者实现技术共享,在满足高性能通信的同时满足复杂多样的感知需求[4]㊂该技术具有超越传统移动通信网络连接的潜力,可以开辟民用无人机㊁智慧交通等全新业务,因此受到了学界的广泛关注[5]㊂波束赋形技术是通信感知一体化的关键技术之一㊂文献[6]提出了通信感知一体化的波束赋形方案,在通信目标信噪比的约束下以目标估计误差为优化目标㊂文献[7]在相同的约束条件下使发射矩阵接近理想的雷达方向图来提高雷达感知的性能㊂为了解决射频资源紧缺的问题,5G将毫米波(millimeter Wave,mmWave)频段写入标准,用于提升传输速率㊂毫米波通信一般使用大规模多输入多输出(Multiple Input Multiple Output,MIMO)技术来增大信号强度[8]㊂随着天线阵列规模的增加,传统的全数字结构成本已经难以承担,因此毫米波通信使用将数字与模拟波束赋形结合起来的混合波束赋形技术㊂基于毫米波频段的通感一体化波束赋形技术也得到了广泛的关注㊂文献[9]提出了通信感知一体化系统的混合波束赋形方案,在满足雷达方向图的条件下,使混合波束赋形矩阵接近理想通信矩阵㊂该方案具有较低的复杂度,且雷达性能较高㊂但是在此方案下通信性能受到抑制,无法实现通信和感知性能的权衡㊂文献[10]采用正交匹配追踪算法得到最优波束赋形矩阵,该算法迭代速度较快,然而在大数据量情况下复杂度较高,且迭代过程中会产生累积误差并影响最终结果㊂现有的研究大多将优化算法的目标设计为使混合波束赋形矩阵逼近全数字波束赋形矩阵,并且通常会在约束通信或感知一者的前提下优化另一者的性能㊂这样做的缺点在于性能上会有所损失,最终求出的结果也不会是最优的㊂因此,针对毫米波MIMO下通感一体化的性能要求,本文提出了基于最小均方误差(Mean Square Error,MSE)准则设计的混合波束赋形算法㊂通过在均方误差指标中引入因子使得优化算法与信道噪声能量相关联,使设计更加准确,同时简化了求解过程㊂通过引入辅助酉矩阵使理想雷达发射矩阵与一体化下的雷达发射矩阵维度相同,可以直接进行均方误差的计算㊂优化的目标函数含有多个待优化变量,难以直接求解,因此本文提出了交替迭代优化算法㊂在假设其他优化目标为最优解的情况下单独优化一个目标,通过不断交替循环实现系统的最优解㊂在求解模拟波束赋形矩阵时,相移器阵列受恒模约束的影响,该问题是非凸优化问题㊂针对该问题,本文提出了坐标迭代优化法来求出该优化问题的最优解㊂仿真结果表明该算法较好地兼顾了通信与感知的性能,实现了二者的融合㊂1㊀毫米波通信感知一体化系统理论基础1.1㊀毫米波大规模MIMO技术5G及今后技术的发展离不开通信速率的不断提高㊂由奈奎斯特第一准则可知,通信速率与信号的带宽成正比㊂4G技术所使用的频段较低,缺乏足够的频带资源继续拓展带宽㊂因此,为了继续提高通信速率,需要利用更高频段的毫米波段㊂相比于中低频段,毫米波段拥有数十倍以上的广阔频段,可以解决带宽资源的紧张问题[11],在毫米波段下的通信与感知性能也能得到极大的提高[12]㊂然而,毫米波也有着不容忽视的缺点,根据弗里斯传输公式[13],接收功率与波长成正比,毫米波更短的波长意味着更大的传输损耗㊂为了弥补这种损耗,在应用中多采用大规模MIMO技术对其进行补偿㊂以一维均匀排布的天线阵列为例,其天线间隔应大于半波长㊂毫米波的波长极短,因此天线间隔在毫米波段下极小,可以实现大规模MIMO传输㊂1.2㊀混合波束赋形系统在传统的全数字波束赋形系统下,每根天线都必须配备一条可以任意改变信号幅度和相位的射频链路㊂然而在大规模MIMO系统中,天线的数量激增,已无法负担为每根天线加装射频链路的巨大成本[14]㊂因此,有研究者提出了使用混合波束赋形技术㊂从图1可以看出,混合波束赋形系统的特点在于使用数个相移器构成模拟波束赋形矩阵[15],减少了数字波束赋形矩阵中射频链路的数量,在很大程度上降低了建设成本㊂其中,传输信号维度为N s,使用了N RF条射频链路,发送天线数量为N t,满足关系N sɤN RF≪N t㊂图1㊀毫米波MIMO系统混合波束赋形方案Fig.1㊀Hybrid beamforming scheme formmWave MIMO system1.3㊀通信感知一体化波束赋形技术在通信感知一体化系统中,同一种波形被同时运用于通信传输和雷达感知,这二者的功能都能通过MIMO混合波束赋形系统实现㊂因此,在求解相应的波束赋形矩阵时,可以做到同时优化通信和感知的性能,这实现了通信与感知性能的兼顾与折中,与一体化的思想一致㊂2㊀基于最小MSE准则的一体化波束赋形设计2.1㊀通信模型在混合波束赋形系统中,用户接收到的信号yɪC N sˑ1可以表示为:y=W H HF RF F BB s+W H n,(1)式中:sɪC N sˑ1为发送的数据信号向量,满足关系E(ss H)=I N s,F BBɪC N RFˑN s为数字波束赋形矩阵, F RFɪC N tˑN RF为模拟波束赋形矩阵,该矩阵仅提供相位变化,因此所有元素的模为1㊂HɪC N rˑN t为信道矩阵,N r为接收端的天线数量,WɪC N rˑN s为接收端的全数字波束赋形矩阵,nɪC N rˑ1为信道噪声矢量,服从均值为0㊁方差为σ2的复高斯分布㊂对于均匀线阵,其阵列响应矢量为:a(θ)=1㊀N[1,e j kd sin(θ),e j2kd sin(θ), ,e j(N-1)kd sin(θ)]T,(2)式中:k=2πλ,d为阵元间隔,通常取d=λ/2,N为天线数,θ为到达角或离开角㊂在毫米波频段下,信道矩阵为Saleh-Valenzuela 模型[16],可以表示为:H=㊀NtN rLðL l=1αl a r(θr,l)a H

RF)=F RF F BB E(ss H)F H BB F H RF=F RF F BB F H BB F H RF㊂(5)假设雷达感知的目标数量为K,相对于基站的离开角为{θt,1,θt,2, ,θt,K}㊂由式(3)可知,信道矩阵表示为L个不同离开角和到达角的散射路径的求和㊂信道的前K个散射路径即为雷达感知K个目标的路径㊂因此信道前K个路径的离开角应为雷达感知的离开角,即为{θt,1,θt,2, ,θt,K},剩下的L-K个离开角和L个到达角均服从[-π/2,π/2]的均匀分布㊂2.3㊀通信感知一体化的最小MSE模型在一体化系统的设计过程中,衡量通信系统性能的主要标准为误比特率(Bit Error Ratio,BER)等㊂在传统波束赋形设计中,通常通过降低MSE来达到降低误比特率的目的㊂本文将这一指标运用到一体化混合波束赋形的应用范围内,目的也是通过降低通信和雷达感知的均方误差来优化通信和感知的各项性能㊂通信性能的MSE定义为接收信号与原始信号的均方误差:MSE c=E( β-1y-s 2F)=E( β-1(W H HF RF F BB s+W H n)-s 2F)= tr(β-2W H HF RF F BB F H BB F H RF H H W-β-1W H HF RF F BB-β-1F H BB F H RF H H W+σ2β-2W H W+I Ns)(6)式中:引入的β因子可以将之后在功率约束下的优化求解问题大大简化,变成以β为优化目标的子问题㊂由雷达感知的波束图公式可知,雷达的波束设计等价于设计雷达的协方差矩阵㊂理想的全数字雷达发射矩阵F radɪC N tˑK为:F rad =[a t (θt ,1),a t (θt ,2), ,a t (θt ,K )]㊂(7)然而,混合波束赋形系统中的雷达发射矩阵为F RF F BB ɪCN t ˑN s,与理想的发射矩阵维度不一致,因此二者不能直接进行MSE 的计算㊂为使二者维度一致,可以引入一个辅助酉矩阵F u ɪC K ˑN s,其满足关系F u F H u =I K ,这样,理想雷达的发射矩阵可以表示为F r =F rad F u ɪCN t ˑN s㊂可以看到,引入辅助酉矩阵后,理想雷达的发射矩阵与混合波束赋形中的发射矩阵维度一致,并且原来理想雷达的方向没有改变,维持了原始的性能㊂辅助酉矩阵可以通过以下的优化问题解出:min F uF c -F rad F u 2Fs.t.㊀F u F Hu=I K{,(8)式中:F c 为理想的通信全数字波束赋形矩阵㊂对信道矩阵进行奇异值分解:H =U V H ㊂(9)取V 的前N s 列即为通信全数字波束赋形矩阵F c ㊂该优化问题表明构造辅助酉矩阵应尽可能减小全数字波束赋形下通信与雷达感知的差异,提高一体化的性能㊂该问题类似于正交普鲁克问题,可以求得F u的闭式解为[18]:F u =U 1CV H 1,(10)式中:U 1和V 1来自于F H rad F c 的奇异值分解F Hrad F c=U 11V H 1,C =[I K ,O K ˑ(N s -K )]㊂由此,雷达感知的MSE 可以定义为:MSE r = F RF F BB -F r 2F =tr(F RF F BB F H BB F H RF -F RF F BB F H r -F r F H BB F H RF +F r F Hr )㊂(11)在一体化的混合波束赋形设计中,需要同时以通信和雷达的性能作为优化对象,因此优化问题的目标函数应同时包含二者的均方误差㊂通感一体化下的混合波束赋形优化问题可以表示为:min W ,F RF ,F BB ,βρMSE c +(1-ρ)MSE r s.t.㊀(F RF )ij =1,∀i ,j F RF F BB 2FɤP ìîíïïïï,(12)式中:ρɪ[0,1]为一权重因子,代表通信性能在优化中所占的比重㊂该优化问题需要考虑模拟波束赋形矩阵的恒模约束和混合波束赋形矩阵的功率约束㊂3㊀基于交替迭代优化算法求解波束赋形设计3.1㊀基于坐标迭代的交替优化上文中通感一体化下的混合波束赋形优化问题涉及到4个待优化变量,难以直接求解㊂因此,可以每次在固定其他变量的条件下交替优化一个变量,通过多轮这样的迭代优化使目标函数最终落入目标区间内㊂①关于W 的子问题可以表示为:min W MSE c ㊂(13)将目标函数MSE c 对W 求偏导并使结果等于零可以得到W 的闭式解为:W =(HF RF F BB F H BB F H RF H H +σ2β-2I N r)-1ˑβ-1HF RF F BB ㊂(14)②关于β的子问题,由于存在发射功率的限制,只有在发射功率达到最大时β才能达到最优值㊂令F bb =β-1F BB 以简化表达,可以得到在发射功率最大时的β值为:β=P -12(tr(F RF F bb F HbbF H RF))-12㊂(15)从求解过程可以看出,若按照未引入β因子的传统MSE 标准来优化,则需要引入拉格朗日乘子将功率约束条件利用起来再进行复杂的求解,但在引入β因子后,就可以将功率约束分解为β的子问题求得闭式解,这无疑大大简化了算法流程㊂③关于F BB 的子问题可以表示为:min F

Review the chart first, and you may not need to call for service. But if you cannot correct the problem, then call the after‐sale service department.Problem Possible CausesRefrigerator does not operate. The refrigerator is plugged in, but there is low voltage. The fuse is blown or the circuit breaker is tripped.Refrigerator has an odor. Foods transmitting odor to the refrigerator.Motor operates for long periods or cycles on and offfrequently. For the refrigerator to operate for a longer period of time in the summer when temperatures are higher.Do not put too much food in the freezer at one time.Do not put foods in the refrigerator until they are cooled. Frequent door openings.Light does not come on. The refrigerator is plugged in, but the light is not on. The light may be damaged.Problem Problem CausesRefrigerator door cannot be properly closed. There may be too much food in the freezer; or the refrigerator may not be level.Refrigerator is making loudnoises. The food is not level in the unit.The refrigerator is not balanced.Refrigerator parts are not properly installed.7.1Summer Weather Tips●The refrigerator enclosure may emit heat during operation, especially in the summer. This iscaused by the radiation of the condenser. This is normal.●Moisture: Moisture can form on the cabinet surface between the doors and collect inside inhumid weather. This is not unusual. The moisture can be wiped away with a dry towel.●Buzz: A buzz can be generated by running the compressor, especially when starting up orshutting down.8.ENERGY SAVING TIPSTry not to open the door too often, especially when the weather is humid. Once you open the door, close it as soon as possible.Every now and then check to see if the appliance is sufficiently ventilated (adequate air circulation behind the appliance).In normal temperature conditions, please arrange the thermostat at the middle setting. Before loading the appliance with packages of fresh food, make sure that the food is cooled to room temperature.Frost or ice crystals on frozen food increase energy consumption, so clean the appliance as soon as the layer is 0.3‐0.5cm thick.If it is the outer condenser, the rear wall should always be clean and free of dust or any impurities.Always consider instructions stated in the Positioning and Energy Saving Tips sections, otherwise the energy consumption might be substantially higher.●The appliance should be located in the coolest area of the room, away from heat‐producing appliances or heating ducts and out of the direct sunlight.●Let hot foods cool to room temperature before placing them in the refrigerator.Overloading the appliance forces the compressor to run longer. Foods that freeze tooslowly may lose quality or spoil.●Be sure to wrap foods properly, and wipe containers dry before placing them in theappliance. This cuts down on frost buildup inside the appliance.●The vegetable and fruit drawers should not be lined with aluminum foil, wax paper orpaper towels. Liners interfere with cold air circulation, making the refrigerator lessefficient.●Organize and label food to reduce door openings and extended searches. Remove asmany items as needed at one time, and close the door as soon as possible.。
