技术领域 technical field
本发明涉及空调器生产领域，尤其涉及生产过程中针对变频空调室外机的测试系统。The invention relates to the field of air conditioner production, in particular to a test system for the outdoor unit of the frequency conversion air conditioner in the production process.
背景技术 Background technique
变频空调是一种使用变频压缩机和模糊控制技术的空调器，能根据室内气温的变化，调节制冷速度。变频空调是相对普通空调来讲的，普通空调的压缩电机采用交流异步电机，转速不变，而变频空调则采用变频压缩机，通过频率变化来调节压缩机转速，使制冷量连续变化，适应空调负荷的需要。Inverter air conditioner is an air conditioner using inverter compressor and fuzzy control technology, which can adjust the cooling speed according to the change of indoor temperature. The frequency conversion air conditioner is compared to the ordinary air conditioner. The compression motor of the ordinary air conditioner adopts an AC asynchronous motor with a constant speed, while the frequency conversion air conditioner uses an inverter compressor to adjust the speed of the compressor through the frequency change, so that the cooling capacity can be continuously changed, which is suitable for air conditioners. load needs.
变频空调采用了变频电源、变频压缩机、电子膨胀阀和微电脑技术的有机结合，使空调性能进一步提高，使用时房间温度波动小，舒适性更佳，对电源电压波动不敏感，压缩机启动后，一般不停机，制冷量在较大的范围内变化，避免了普通空调的频繁开停，延长了压缩机的寿命，同时具有高效、节能的特点。The frequency conversion air conditioner adopts the organic combination of frequency conversion power supply, frequency conversion compressor, electronic expansion valve and microcomputer technology, which further improves the performance of the air conditioner. During use, the temperature fluctuation of the room is small, the comfort is better, and it is not sensitive to the fluctuation of the power supply voltage. , generally does not stop, the cooling capacity changes in a large range, avoids the frequent start and stop of ordinary air conditioners, prolongs the life of the compressor, and has the characteristics of high efficiency and energy saving.
然而，实现上述功能及优点的同时，使得变频空调的控制系统和室外机变频系统较为复杂，对元器件要求较高，相比较普通空调，变频空调的故障率较高。所以，生产过程中，对变频空调室外机的检测步骤非常关键。However, while achieving the above functions and advantages, the control system of the inverter air conditioner and the inverter system of the outdoor unit are more complicated, and the requirements for components are higher. Compared with ordinary air conditioners, the failure rate of the inverter air conditioner is higher. Therefore, in the production process, the detection steps of the outdoor unit of the inverter air conditioner are very critical.
目前，变频空调室外机的生产过程中，没有专用的变频测试工装，各被测的变频室外机需携带内机控制板，通过操作遥控器发送命令(如启动、制冷、制热、关机等)，进而进行检测，其检测过程较为烦琐，人为介入多，不能实时获取室外机运行参数及状态的信息。At present, in the production process of the inverter air conditioner outdoor unit, there is no special inverter test tooling, and each inverter outdoor unit to be tested needs to carry an internal unit control panel, and send commands (such as start, cool, heat, shut down, etc.) by operating the remote control , and then carry out detection, the detection process is cumbersome, and there are many human interventions, and it is impossible to obtain the information of the operating parameters and status of the outdoor unit in real time.
此外，变频空调存在多种机型，各种机型内、外机之间进行通讯的协议是不同的。所以，生产线更换机型时，对应的测试系统需要更换，给测试带来不便，影响总装生产检验效率。In addition, there are many types of inverter air conditioners, and the communication protocols between the internal and external units of each type are different. Therefore, when the model of the production line is changed, the corresponding test system needs to be replaced, which brings inconvenience to the test and affects the efficiency of final assembly production inspection.
