Problems solved by technology

In the refrigerator manufacturing process, in order to prevent ice blockage during refrigeration operation, and to ensure the stability of the operating current of the compressor, the reduction of power consumption, the stability of the cooling effect, the stability of the compressor, and the service life of the compressor, it is necessary to replace the compressor inside the refrigerator. Vacuumize the air, and the vacuum needs to meet the vacuum degree. Generally, the vacuuming time is controlled at about 15-20 minutes. Therefore, the refrigerator manufacturer’s line body has vacuuming stations. In order to meet the production efficiency, the number of vacuuming stations is generally It is between 40-60. However, although the existing line body can meet the efficiency and time of vacuuming, it requires the operator to insert the vacuum joint into the refrigerator, and the vacuum value cannot be saved.

At present, the vacuuming lines of refrigerators produced by various companies are ring-shaped production lines. The vacuum pumps are evenly arranged on the circular track and run at a constant speed. The probability of error is high, and the vacuum value cannot be saved, let alone traceable data; Zigbee technology is a wireless network communication technology standard that has only emerged in recent years, low power consumption, low cost, low speed, high capacity, high security, and license-free frequency bands are Its outstanding features, and its advantages of openness, free, massive address space, and seamless integration with the Internet, have attracted more and more attention. At present, many companies purchase the core chips of Texas Instruments TI, and develop on the basis of them. Related to the dedicated communication module based on Zigbee technology, the smart meter can directly use the RS485 to Zigbee wireless module to make the data information of the meter wireless; for example, Chinese patent 201110133315. Including the data collector, the ZIGBEE wireless adapter control unit is connected with the data collector, the ZIGBEE wireless adapter acquisition unit is set near each sensor, and the ZIGBEE wireless adapter control unit and the ZIGBEE wireless adapter acquisition unit are connected through a built-in wireless module based on ZIGBEE technology For data interaction, it provides a wireless collection solution for sensor data collection that is not suitable for wired transmission within the micro-area; there is no report on the application of Zigbee technology in the vacuum section of the refrigerator production line.
