Description

A Method for Assigning Addresses of Water Pump Controller Test System

technical field

The invention relates to a water pump controller test system and an address distribution method, which are used for setting the address distribution of the water pump controller in the test system, and the method can be extended to the address distribution of various equipment test systems.

Background technique

The water pump controller test system is a platform for comprehensive testing of various functions and performance parameters of the water pump controller. Its stability and performance are directly related to the detection of product defects of the water pump controller. It is the last quality check before the water pump controller leaves the factory. Its importance is self-evident.

The water pump controller test system mainly includes the upper computer (PC), test cabinet controller, related performance test equipment and the water pump controller to be tested. On the one hand, the host computer communicates the test process (for example, overvoltage function test, undervoltage function test, overload function test, dry running function test, phase loss function test, water shortage function test, water overflow function test, etc.) The setting parameters (such as input voltage parameters, operating current parameters, flow parameters, water level parameters, etc.) are sent to the test cabinet controller, and the test cabinet controller analyzes the received setting parameters to control and adjust related performance tests. The equipment parameters enable the water pump controller to execute the corresponding test process and access the corresponding setting parameters; on the other hand, the test cabinet controller reports the test result parameters and working status of all the water pump controllers in the test cabinet to the host computer through the communication bus . The upper computer will analyze the received parameters and set parameters and functions of the water pump controller with a unique IP address, and obtain the test report corresponding to each water pump controller, so that it is convenient for technicians to carry out data analysis and technical improvement. Determine the IP number of the faulty water pump controller and the location of the IP number for the sound and light alarm, realize the automation and intelligence of the test system, and improve the test efficiency and test reliability. The realization of the above test function involves the allocation method of the IP address of the water pump controller test system.

In the prior art, there are mainly static address allocation methods and dynamic address allocation methods for test system address allocation methods. Static address allocation methods mainly include the following methods: ①Dial code setting method; that is, set the IP number of the controller by dialing code; ②Wireless remote control setting: that is, through a dedicated wireless remote control device Set the IP number of the device; ③Program burning method: set the system IP number in the source code and solidify it into the chip; Once set, the IP remains unchanged as long as it is not reset. The dynamic address allocation method is mainly based on the unique SN serial number setting in the chip, which mainly obtains the unique IP number by obtaining the serial number of the main controller chip of the online device, sorting or other IP address generation algorithms. As soon as another device is plugged into the test system, that device issues a request to assign an address request. After receiving the request, the test cabinet test cabinet controller redistributes the IP of the device according to the previous IP generation method. The above two address assignment methods have the following problems in the controller test system: how to ensure that the IP number of the controller placed at a specific number on the test cabinet is consistent with the number. This is mainly based on how the host computer can quickly locate the controller based on the data obtained by the IP number test if the IP number is inconsistent with the number on the test cabinet. Because the test result information is identified by the host computer based on the IP address of the controller, as long as the location number information of the controller is consistent with the IP address information, the operator can quickly and accurately locate the number according to the IP value to avoid the outflow of faulty and defective products. In order to achieve the above goals, the existing static address allocation method and the dynamic address allocation method both have limitations. As far as the static address allocation method is concerned, it needs to find out the controller with the same number as the placement location and place it at the location. On the one hand, this increases the work intensity; on the other hand, its reliability is too low. Once the controller IP is inconsistent with the location number, it is possible to mistake the product with no problem as a fault, and the defective product will flow into the market instead. . As far as the above-mentioned dynamic address allocation method is concerned, it is almost difficult to realize that the IP is consistent with the location number.
