Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the present embodiment provides an online detection system for an air conditioner, including:
the air conditioner detection station 1 is arranged at the tail end of an air conditioner production line and is used for butting with the air conditioner production line;
the production line working condition monitoring device 2 is used for monitoring the working condition of each detection station of the air conditioner and transmitting the detected working condition to the PLC 6; for example, the production line working condition monitoring device 2 monitors whether a production line dragging motor stops or not and whether an air conditioner stops in place or not at a detection station or not;
a product recognition device 3, the product recognition device 3 having a scanning gun 31;
the testing device 4 is used for testing various performance parameters of the air conditioner to be tested; the performance parameters of the air conditioner mainly refer to electric parameters in the operation process of the air conditioner, such as operating current, operating voltage, operating power and other parameters;
a printer 5;
the PLC 6 is respectively connected with the air conditioner detection station 1, the production line working condition monitoring device 2, the product identification device 3, the testing device 4 and the printer 5, and the PLC 6 is connected with the scanning gun 31 through an RS232 interface; the PLC controller 6 is provided with a display screen 61, and the PLC controller 6 is used for controlling the product identification device and the testing device according to the working condition monitored by the production line working condition monitoring device and receiving the identification result of the product identification device and the testing result of the testing device; the PLC controller 6 reads the code scanning information through the scanning gun 31 and transmits the read scanning information to a display screen of the PLC controller 6; currently, air conditioner products are labeled with two-dimensional code labels loaded with product information in the production process of a production line, and the product information generally comprises product batch and product identity information. Therefore, the scanning gun 31 can scan the two-dimensional code label on the air conditioner to be tested to obtain the specific product information of the current air conditioner to be tested.
The data memory 7 is connected with the PLC 6 and used for storing various test data of the air conditioner processed by the PLC;
and a monitoring management system 8, wherein the monitoring management system 8 is connected with the PLC 6. The monitoring management system 8 can be connected with the PLC controller 6 through a 5G mode. It should be noted that the monitoring management system 8 can query the detection data of each air conditioner according to the bar code, and output the data to the printer 5 in a report form, so that the printer 5 prints the detection data corresponding to each air conditioner. The PLC 6 can control multi-station parallel online detection, and realizes product information identification and input, safety performance test data acquisition, starting and operation performance test of the air conditioner. Specifically, aiming at the starting and running performance test process, the PLC 6 controls the remote controller and the autotransformer controller of the execution unit, so that the air conditioner to be tested can be automatically started and stopped at low voltage and full voltage, and the performance index detection is completed.
In order to prompt the prior detection condition of the air conditioner, the online detection system of the embodiment further comprises an alarm device 9, and the alarm device 9 is connected with the PLC 6.
