Description
技术领域Technical Field
本发明涉及空调测试技术领域，尤其涉及一种空调辅助电加热功率自动测试系统和测试方法。The invention relates to the technical field of air conditioning testing, and in particular to an automatic testing system and method for auxiliary electric heating power of an air conditioner.
背景技术Background technique
现在，在人们的日常生活和工作中，空调已经成为必不可少的家电。无论是夏天制冷还是冬天制热，空调的性能都给用户带来了极大的影响。尤其是，冬天热泵空调制热效果欠佳，为提升更好的使用体验空调一般都有辅助电加热功能。辅助电加热有电热丝型电加热发热管、陶瓷PTC型半导体加热器等多种型式。在电压、风速、温度不变情况下，电热丝型辅助电加热功率恒定，而PTC型辅助电加热启动时功率较大(1.5-3倍额定功率)、约30秒后下降到额定功率。辅助电加热作为发热器件，容易导致发热起火安全事故，其安全要求非常高。当空调控制器未开启电加热功能时，辅助电加热不能工作；开启电加热功能时，辅助电加热功率应在额定值范围内。Nowadays, air conditioners have become indispensable household appliances in people's daily life and work. Whether it is cooling in summer or heating in winter, the performance of air conditioners has a great impact on users. In particular, the heating effect of heat pump air conditioners in winter is poor. In order to improve the use experience, air conditioners generally have auxiliary electric heating functions. Auxiliary electric heating has many types, such as electric heating wire type electric heating tubes and ceramic PTC type semiconductor heaters. When the voltage, wind speed and temperature remain unchanged, the power of the electric heating wire type auxiliary electric heating is constant, while the power of the PTC type auxiliary electric heating is large when it starts (1.5-3 times the rated power) and drops to the rated power after about 30 seconds. As a heating device, auxiliary electric heating is prone to heat and fire safety accidents, and its safety requirements are very high. When the air conditioner controller does not turn on the electric heating function, the auxiliary electric heating cannot work; when the electric heating function is turned on, the auxiliary electric heating power should be within the rated value range.
因此，空调在出厂前的检测中，辅助电加热的性能的测试是至关重要的检测项目之一。但是，将辅助电加热装配在整机上匹配控制系统进行测试，测试效率低，需要对多个测试项目进行严格的测试。例如，申请号为CN202010651600.X的中国发明专利公开了一种电加热管测试系统及方法，本申请涉及自动测试技术领域，具体涉及一种电加热管测试系统及方法，解决了相关技术中发热管未经检测流入下道工序、对发热管的检测结果误差较大的问题。该系统包括：第一控制板发送开启电加热管的指令；第二控制板与第一控制板连接，接收第一控制板发送的开启电加热管的指令，并根据该控制指令控制电加热管开启；第一测试装置与第一控制板连接，对处于开启状态的电加热管进行状态参数采集，并将采集到的状态参数传输至上位机；上位机与第一测试装置连接，生成测试指令，将测试指令发送至第一控制板，以使第一控制板发送开启电加热管的指令，接收第一测试装置传输的状态参数，当状态参数与预设状态参数不匹配时，生成电加热管状态异常的指令。陶瓷PTC加热器在不同的工作阶段功率变化很大，上述方法未对其进行分阶段的详细的测试，测试结果不准确。在线测试时，通过上述方法无法避免时读取多台空调的功率值，导致测试结果混乱。在线测试时，可能出现该工位空缺，降低了检测效率。Therefore, in the inspection of air conditioners before leaving the factory, the performance test of auxiliary electric heating is one of the most important inspection items. However, the auxiliary electric heating is assembled on the whole machine and matched with the control system for testing, which has low test efficiency and requires rigorous testing of multiple test items. For example, the Chinese invention patent with application number CN202010651600.X discloses an electric heating tube testing system and method. This application relates to the field of automatic testing technology, and specifically to an electric heating tube testing system and method, which solves the problem in the related technology that the heating tube flows into the next process without detection and the detection results of the heating tube have large errors. The system includes: a first control panel sends an instruction to turn on the electric heating tube; a second control panel is connected to the first control panel, receives the instruction to turn on the electric heating tube sent by the first control panel, and controls the electric heating tube to turn on according to the control instruction; a first test device is connected to the first control panel, collects state parameters of the electric heating tube in the turned-on state, and transmits the collected state parameters to the host computer; the host computer is connected to the first test device, generates a test instruction, and sends the test instruction to the first control panel, so that the first control panel sends an instruction to turn on the electric heating tube, receives the state parameters transmitted by the first test device, and generates an instruction that the state of the electric heating tube is abnormal when the state parameters do not match the preset state parameters. The power of the ceramic PTC heater varies greatly in different working stages. The above method does not perform detailed tests on it in stages, and the test results are inaccurate. During online testing, the power values of multiple air conditioners cannot be avoided by the above method, resulting in confusion in the test results. During online testing, the station may be vacant, which reduces the detection efficiency.

下面将参考附图并结合实施例来详细说明本发明。The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
如图1是图3所示，一种空调辅助电加热功率自动测试系统，包括：传送设备3，电源设备2和检测设备4。FIG1 is a diagram showing an automatic test system for auxiliary electric heating power of an air conditioner, comprising: a transmission device 3 , a power supply device 2 and a detection device 4 .
传送设备3用于承载和传送空调1。检测区沿所述传送设备3至少设置一个。电源设备2，靠近所述传送设备3设置，为所述传送设备3和所述空调1提供电源。检测设备4包括功率测试仪42，信息检测仪41，遥控器43和处理装置44。功率测试仪42靠近所述传送设备3设置于所述检测区，获取所述空调1的功率信息。信息检测仪41，靠近所述传送设备3设置，检测所述空调1的设备信息。遥控器43，向所述空调1发射遥控信号。处理装置44，接收所述设备信息，接收所述功率信息，并且，对所述功率信息进行分析处理，获取测试结果。The transmission device 3 is used to carry and transmit the air conditioner 1. At least one detection area is set along the transmission device 3. The power supply device 2 is set close to the transmission device 3 to provide power for the transmission device 3 and the air conditioner 1. The detection device 4 includes a power tester 42, an information detector 41, a remote controller 43 and a processing device 44. The power tester 42 is set in the detection area close to the transmission device 3 to obtain the power information of the air conditioner 1. The information detector 41 is set close to the transmission device 3 to detect the device information of the air conditioner 1. The remote controller 43 transmits a remote control signal to the air conditioner 1. The processing device 44 receives the device information, receives the power information, and analyzes and processes the power information to obtain the test result.
将空调1放置于传送设备3上，在传送的过程中，可以对经过指定时间的电加热的空调1的功率进行测试，随着电加热的时间的变化，测试功率的变化，以达到对空调1辅助电加热的性能的测试目的。将测试结果通过处理装置4进行处理后输出测试结果，实现了对空调1的辅助电加热进行的自动测试作业。提高了测试结果准确性，避免了多台空调1同时测试，导致测试结果混乱的问题，提高了检测效率。The air conditioner 1 is placed on the conveying device 3. During the conveying process, the power of the air conditioner 1 after the electric heating for a specified time can be tested. As the electric heating time changes, the test power changes, so as to achieve the purpose of testing the performance of the auxiliary electric heating of the air conditioner 1. The test results are processed by the processing device 4 and then output, realizing the automatic test operation of the auxiliary electric heating of the air conditioner 1. The accuracy of the test results is improved, the problem of confusing test results caused by testing multiple air conditioners 1 at the same time is avoided, and the detection efficiency is improved.
具体的，所述传送设备包括动力装置、传送带和控制器。传送带与所述动力装置连接用于承载和传送所述空调1。控制器，与所述动力装置连接，用于控制所述传送带的速度。Specifically, the conveying device includes a power device, a conveyor belt and a controller. The conveyor belt is connected to the power device for carrying and conveying the air conditioner 1. The controller is connected to the power device and is used to control the speed of the conveyor belt.
空调1在测试时，从测试起始点L1开始通过传送带沿传送方向I传送至测试终止点L2，测试的时间通过处理装置44确定后，通过控制器控制动力设备带动传送带的运行速度。在测试过程中，传送带上仅测试一台空调1，在处理装置44确定的测试时间的基础上，通过控制器控制传送带尽量提高运行速度，以便提高测试效率。When the air conditioner 1 is tested, it is transported from the test starting point L1 to the test ending point L2 by the conveyor belt along the conveying direction I. After the test time is determined by the processing device 44, the controller controls the power device to drive the running speed of the conveyor belt. During the test, only one air conditioner 1 is tested on the conveyor belt. Based on the test time determined by the processing device 44, the controller controls the conveyor belt to increase the running speed as much as possible to improve the test efficiency.
作为一个实施例，如图4所示，电热丝型电加热发热管为恒电阻，功率恒定，测试需要的时间较短(t4-t0约20s)。如图5所示，陶瓷PTC型半导体加热器，其功率在通电瞬间上升到1.5倍-3倍额定功率，其后缓慢下降到稳态值。PTC加热器的电阻随温度变化，功率稳定下来需要较长时间(t5-t0,约80s)。因此在实际测试时需根据负载差别进行速度控制。其中，t0时刻为空调1未承载于传送带上，或空调1未接通电源设备2，此时，瞬时功率P＝0。t4为PTC功率达到峰值的时刻。t5为PTC功率达到稳态值的时刻。As an embodiment, as shown in FIG4 , the electric heating wire type electric heating tube has a constant resistance and a constant power, and the test requires a short time (t4-t0 is about 20s). As shown in FIG5 , the power of the ceramic PTC type semiconductor heater rises to 1.5 times to 3 times the rated power at the moment of power-on, and then slowly decreases to a steady-state value. The resistance of the PTC heater changes with temperature, and it takes a long time for the power to stabilize (t5-t0, about 80s). Therefore, in actual testing, speed control is required according to the load difference. Among them, the moment t0 is when the air conditioner 1 is not carried on the conveyor belt, or the air conditioner 1 is not connected to the power supply device 2. At this time, the instantaneous power P=0. t4 is the moment when the PTC power reaches its peak. t5 is the moment when the PTC power reaches a steady-state value.
检测设备4沿所述传送带按照指定检测工序的顺序布置，处理装置44与信息检测仪41和功率检测仪42通过电缆连接，并相互传输数据，因此，将处理装置44靠近传送带设置。处理装置44与信息检测仪41和功率检测仪42也可以无线连接，因此处理装置44可以远程设置，甚至设置在云端，检测人员可以通过移动终端与云端的处理装置44无线通讯。The detection equipment 4 is arranged along the conveyor belt in the order of the designated detection process, and the processing device 44 is connected to the information detector 41 and the power detector 42 by cables and transmits data to each other, so the processing device 44 is set close to the conveyor belt. The processing device 44 can also be wirelessly connected to the information detector 41 and the power detector 42, so the processing device 44 can be set remotely, or even set in the cloud, and the detection personnel can communicate wirelessly with the processing device 44 in the cloud through a mobile terminal.
进一步的，如图2所示，所述电源设备2包括变频电源(图中未示)、导电板组件和接线器21。导电板组件对应所述检测区设置于所述传送带的下方，与所述变频电源电连接。接线器21设置在所述传送带的上方，与所述导电板组件和所述空调1电连接。Further, as shown in FIG2 , the power supply device 2 includes a variable frequency power supply (not shown), a conductive plate assembly and a connector 21. The conductive plate assembly is arranged below the conveyor belt corresponding to the detection area and is electrically connected to the variable frequency power supply. The connector 21 is arranged above the conveyor belt and is electrically connected to the conductive plate assembly and the air conditioner 1.
通过上述结构，空调1接通电源设备2。同时，电源设备给传送设备3和检测设备4供电。Through the above structure, the air conditioner 1 is connected to the power supply device 2. At the same time, the power supply device supplies power to the transmission device 3 and the detection device 4.
进一步的，所述电源设备还包括导电弹片24，所述接线器21与所述导电板组件之间通过所述导电弹片24电连接。当所述传送带承载所述空调1移动到所述检测区的外部时，所述导电弹片24与所述导电板组件分离。当所述传送带承载所述空调移动到所述检测区时，所述导电弹片24与所述导电板组件接触连接。Furthermore, the power supply device further includes a conductive spring 24, and the connector 21 is electrically connected to the conductive plate assembly through the conductive spring 24. When the conveyor belt carries the air conditioner 1 to move outside the detection area, the conductive spring 24 is separated from the conductive plate assembly. When the conveyor belt carries the air conditioner to move to the detection area, the conductive spring 24 is in contact with the conductive plate assembly.
通过导电弹片24使得空调1被放置于传送带上时，通过空调1的重量压下导电弹片24，使其与导电板组件连接，使得空调1自动与电源设备连接。当传送带上未放置空调1时，导电弹片24与导电板组件处于分离状态，自动切断电源。操作方便，安全性高。When the air conditioner 1 is placed on the conveyor belt through the conductive spring sheet 24, the weight of the air conditioner 1 presses down the conductive spring sheet 24 to connect it with the conductive plate assembly, so that the air conditioner 1 is automatically connected to the power supply device. When the air conditioner 1 is not placed on the conveyor belt, the conductive spring sheet 24 and the conductive plate assembly are in a separated state, and the power supply is automatically cut off. The operation is convenient and the safety is high.
进一步的，所述导电板组件包括第一导电板22和第二导电板23，通过所述导电弹片24分别与所述接线器21的两个电极电连接。Furthermore, the conductive plate assembly includes a first conductive plate 22 and a second conductive plate 23 , which are electrically connected to two electrodes of the connector 21 through the conductive springs 24 .
第一导电板22和第二导电板23分别对应接线器21的两个电极。The first conductive plate 22 and the second conductive plate 23 correspond to two electrodes of the connector 21 respectively.
