[0001] The present invention relates to the technical field of automatic control methods. More specifically, the present invention relates to a method for automatically configuring programmable input / output ports. Background Art

[0002] For current diesel generator set controllers, there are many user-defined functions. Each time, the user's customized functions are written into the code, and then it is marked what function is customized by which user. This code is downloaded into the corresponding controller.

[0003] Such controllers mainly have the following problems: 1. When adding new functions, the code needs to be modified, which is not convenient for code management. For the current situation where there are many user-defined functions, developers need to perform secondary development, and the development and maintenance costs are relatively high; 2. It is not convenient for product traceability and maintenance. Summary of the Invention

[0024] The following combines the description of the drawings to explain and illustrate in detail the method for automatically configuring programmable input / output ports provided by the present invention.

[0025] The method for automatically configuring programmable input / output ports provided by the present invention writes all the functions that the user wants to customize in the controller. The user only needs to configure the host computer module into the result they want and download it to the controller. The controller will implement its functions according to the user's configuration. In this way, all the functions of the user can be completed through the host computer + lower computer, which is convenient for management and reduces the intermediate development cycle.

[0026] In some embodiments, the present invention provides a method for automatically configuring programmable input / output ports. The controller communicates with the host computer, and the controller obtains control data through the host computer, such as Figure 1 shown, the method includes:

[0027] Hardware connection, the controller is connected to the host computer;

[0028] Download the program, select the control program on the host computer control interface and download it to the controller;

[0029] When the controller successfully downloads the program, execute the relevant control operations.

[0030] Optionally, the specific method includes:

[0031] Step 1: The host computer configures its functions according to user requirements;

[0032] Step 2: Send the configured functions to the controller through the serial port;

[0033] Step 3: After receiving the data, the controller parses and processes the data;

[0034] Step 4: After processing, determine whether it is consistent with the settings of the controller. If it is consistent, the controller executes this configuration function; if not, it does not execute;

[0035] Step 5: When the next instruction is updated, the controller executes the updated function.

[0036] In some embodiments, as Figure 2 shown, the controller downloading the program includes:

[0037] The controller receives the control program from the host computer;

[0038] Control to determine whether the control program is correct,

[0039] When the control program is judged to be correct, the controller can execute the control action,

[0040] When the control program is judged to be incorrect, receive the control program from the host computer again.

[0041] In some embodiments, the host computer is a PLC (Programmable Logic Controller), as Figure 1 shown, the specific method includes:

[0042] Step 1: Hardware connection: Open the host computer (PLC) interface and connect the controller to the host computer through the serial port.

[0043] The host computer includes a control screen, i.e., a control interface. Multiple icons are displayed on the control screen, and the icons can be dragged on the control screen to achieve the setting and output of different functions. Optionally, the control screen is a touch screen, and the icons can be dragged by touching the screen with a finger. Alternatively, the icons can also be dragged by using an external control device such as a mouse.

[0044] Step 2: Select the model and click "Connect" on the interface. Check whether the connection button of the host computer is green. Green indicates connection, and red indicates no connection.

[0045] Before the host computer is connected to the controller, select the port number, baud rate, parity bit, etc. of the serial port on the control screen of the host computer. After the selection is completed, click "Connect". When this port number is not occupied, the connection is successful.

[0046] Step 3: After connection, drag the small icons on the interface to complete its simple functions with conditions + actions + settings.

[0047] After the host computer is successfully connected to the controller, the condition icons and action icons on the control screen of the host computer can be dragged. The control program includes a condition program and an action program. Optionally, the condition can be the 3rd day in the date, and the action can be to set Flag 1 to 1 (associated with Output Port 1).

[0048] Step 4: After the settings are completed, the host computer has a simple simulation interface, where the effect can be simulated to check whether it is correct.

[0049] Step 5: After it is correct, download the set program to the controller.

[0050] The control program (conditions + actions) set in the host computer is downloaded to the controller. After receiving the instruction, the controller starts to parse. When it is found that the condition is the 3rd day and the action is to set the flag to 1 (associated with Output Port 1), the date in the real-time time read by the controller's RTC (Real-Time Clock) is compared with the one sent from the host computer. When the conditions are the same, the corresponding action is executed.

[0051] Optionally, the data format of the control program sent to the controller is a structure: the members are unsigned char plcsumnum and unsigned char data[index]

[16] ; plcsumnum is the total number of plcs, data[index]

[16] is the data content in each plc, and index is the number of plcs. In this way, the data sent from the host computer is received through this structure, and the controller can parse the command sent from the host computer by judging the content in the structure and then judge and execute it.

[0052] Among them, the host computer is configured with condition (3 days) + action flag 1 set to 1 (associated with output port 1). Then plcsumnum is 4 (condition + action + end + end bit), a total of 65 unsigned char data. The total data content is: one-bit plcsumnum + condition bit content of 16 unsigned char data + action bit content of 16 data + 16 ends + end bit content of 16 data.

[0053] Step 6: After downloading the program to the controller, check the result and execute the corresponding action when the condition is met. When the condition is satisfied, download the program to the controller, and it can be seen that output port 1 of the controller is set to 1.

[0054] The method for automatically configuring programmable input / output ports provided by the present invention can implement all customized functions of users through the host computer and the controller, without the need for secondary development of customized functions, facilitating code management and maintenance, and reducing development costs. Moreover, the operation method of the automatically programmable input / output port is simple, and the operation method can be recorded as a video and sent to users. Technicians and operators can simply operate the configuration requirements through the recorded video, download them to the controller, and verify its configuration function.
