It should be noted that, in order to ensure the production efficiency of the variable frequency electric control system, the number of times that the server sends the configuration file may be preset, for example, 3 times, and if no flag bit that is fed back is received when the configuration file is sent for 3 times, an alarm is given to manually implement writing in the compressor driving parameters.
Example 3
Referring to fig. 3, based on the compressor driving parameter configuration system of the foregoing embodiment, an embodiment of the present invention further provides a compressor driving parameter configuration method, where the method includes the following steps:
In this embodiment, since the power of the WiFi module is supplied from the display panel, the WiFi module is powered on after the display panel is powered on. Network information is configured inside the WiFi module, and after the WiFi module is powered on, the WiFi module can automatically inquire and match a local router. And when the router is in an open state, the WiFi module is connected with the router.
The WiFi module in each variable-frequency electric control system is configured with an identity code for representing a unique identity, wherein the identity code is unique, so that the identity code can be used for representing the unique identity of the variable-frequency electric control system.
The server is connected with the router through a network, and the router forwards the identity identification code sent by the WiFi module to the server, so that data interaction between the server and the variable-frequency electric control system can be realized.
In the production process of the variable-frequency electric control system, every time one variable-frequency electric control system is assembled, the identity identification code of the WiFi module in the variable-frequency electric control system and the driving parameters of the compressor in the variable-frequency electric control system are stored in a server. Wherein the driving parameters of the compressor stored in the server are stored in a configuration file.
Therefore, the server stores the corresponding relationship between the identification code and the configuration file, for example, if there are N frequency conversion electronic control systems, where N is an integer not less than 1, the corresponding relationship stored in the server may be as shown in table 1 below.
Table 1:
after receiving the id code, the server searches in the table 1, for example, if the received id code is id code 1, it may find that the configuration file corresponding to the id code is configuration file 1, and therefore, sends the configuration file 1 to the router.
Further, in order to prevent the configuration file from being tampered during the transmission process or prevent the configuration file searched and transmitted from being incorrect, a drive check code of the drive parameter may be further stored in the server. The drive check code is obtained by calculating the drive parameters in the configuration file by using preset check logic. This storage may be as shown in table 2.
Table 2:
after finding the corresponding configuration file, the server sends the driving parameters contained in the configuration file and the corresponding driving check code to the router, and the router forwards the driving parameters and the corresponding driving check code to the WiFi module.
And 305, the WiFi module sends the configuration file to the display panel body, and the display panel body stores the configuration file into the Flash memory.
The Flash memory is also called Flash memory, and belongs to one of memory devices, which is a Non-Volatile (Non-Volatile) memory. The Flash memory can hold data for a long time without current supply, and the storage characteristic of the Flash memory is equivalent to that of a hard disk, and the characteristic is the basis of the Flash memory which becomes a storage medium of various portable digital devices.
Therefore, after the configuration file is forwarded to the display panel body by the WiFi module, the display panel body can store the configuration file into the Flash memory, so that the driving parameters which are included in the configuration file and matched with the model of the compressor in the variable-frequency electric control system are stored in the variable-frequency electric control system for a long time.
Further, in order to prevent the configuration file from being tampered in the transmission process or prevent the configuration file searched and transmitted from being wrong, when the configuration file sent by the server also includes the drive check code, the display panel body can calculate the configuration file by using a preset check logic to obtain the drive code, the drive code is compared with the received drive check code, if the comparison result is the same, the received configuration file is correct, and the correct configuration file is stored in the Flash memory; if the comparison result is not the same, the received configuration file is not correct.
In order to ensure that a correct configuration file is stored in a Flash memory of a display panel in the variable-frequency electric control system, the configuration file can be further stored in a flag bit mode.
Specifically, when the display panel body determines that the configuration file is correct through comparison of the drive code and the drive check code, the configuration file is stored in a Flash memory, a flag bit used for representing passing of check is fed back to a WiFi module, the WiFi module sends the flag bit to a server through a router, and if the configuration file is determined to be wrong according to different comparison results, the flag bit is not sent to the server.
And if the time period for timing is less than the preset waiting time period and the server receives the flag bit, the server determines that the configuration file is correctly transmitted, successfully stores the configuration file in the variable-frequency electric control system, and records the state. If the server does not receive the flag bit when the timing time period is equal to the preset waiting time period, the server determines that the configuration file is sent wrongly, so that the server can continuously acquire the configuration file corresponding to the identity code and send the continuously acquired configuration file to the WiFi module through the router.
It should be noted that, in order to ensure the production efficiency of the variable frequency electric control system, the number of times that the server sends the configuration file may be preset, for example, 3 times, and if no flag bit that is fed back is received when the configuration file is sent for 3 times, an alarm is given to manually implement writing in the compressor driving parameters.
In this embodiment, the format of the configuration file sent by the server to the router may be one of a bin format, a word format, a txt format, and an excel format.
When the configuration file is in a bin format, a subsequent WiFi module can directly read data in the configuration file after receiving the configuration file, and if the configuration file is in another format, for example, one of a word format, a txt format, and an excel format, the WiFi module cannot directly read the data in the configuration file, and the configuration file needs to be read and stored through a reading module configured on the display panel body after being transmitted to the display panel body. Therefore, the configuration file sent by the server to the router is preferably in the bin format.
The above processes are all configuration processes of the compressor driving parameters realized by the variable frequency electric control system after the assembly is completed and before the variable frequency electric control system leaves the factory, and after the variable frequency electric control system leaves the factory, the driving process of the compressor may include the following steps: after the variable-frequency electric control system is powered on every time, the display panel body reads the configuration file stored in the Flash memory and sends the configuration file to the main control panel; and the main control board forwards the configuration file to the driving board, and the driving board drives the compressor according to the configuration file.
Further, after receiving the configuration file, the driver board may send a flag bit for indicating successful receiving to the main control board, the main control board forwards the flag bit to the display panel, and the display panel may determine that the driver board successfully receives the driving parameters according to the flag bit, thereby implementing conversion from the display panel parameter mode to the command mode.
Wherein the main control board functions as a bridge between the display panel and the driving board.
The data interaction between the display panel and the main control panel is realized according to a communication protocol between the display panel and the main control panel.
