[0002] Currently, the communication between the generator set controller and the host computer (or terminal device) is generally performed by USB, RS485, RS232, MODBUS TCP / IP, CAN (Controller Area Network) and other methods. However, the three communication methods of USB, RS485 and RS232 cannot meet the needs of long-distance transmission, so they cannot meet the needs of long-distance communication in scenarios such as trains and factory areas. MODBUS TCP / IP and CAN can perform long-distance high-speed data transmission, but the above methods need to install a specific host computer program on the PC when used, and the PC needs to have a COM port. If there is no COM port, a converter is needed, which is very inconvenient and cannot meet the needs of various users. SUMMARY

[0030] The names of the messages or information exchanged between the plurality of devices in the embodiments of the present disclosure are only for illustrative purposes, and are not intended to limit the scope of the messages or information.

[0031] The following refers to the accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification. Figure 1 A method for a terminal device to communicate with a generator set controller is described. The method can be implemented by a system for a terminal device to communicate with a generator set controller. The system includes a generator set controller and a terminal device. The terminal device is a network-capable electronic device, such as a mobile phone, a computer, a tablet computer, a server, etc. The method includes the following steps:

[0032] S1, the generator set controller initializes WEBSERVER and WEBSOCKETSERVER, and encapsulates the data to be sent into a sending list according to a preset format.

[0033] The WEBSERVER is also known as a web server in Chinese, and can parse the HTTP (HyperText Transfer Protocol) protocol. Therefore, the WEBSERVER can be used to process HTTP requests. The WEBSOCKETSERVER can be used to send data, respond to general statements, and respond to inquiry statements.

[0034] The sending list can include state indication data, timer data, engine data, sensor data, mains data, power generation data, load data, alarm data, input port data, output port data, historical data, version data, and configuration data.

[0035] In one possible implementation, after the generator set controller initializes the WEBSERVER and WEBSOCKETSERVER, it can wait for a connection request from a terminal device. Alternatively, the method for initializing the WEBSERVER and WEBSOCKETSERVER by the generator set controller in S1 can be as follows:

[0036] An object my_websocket of the websocketservermanager class is defined, and the object my_websocket is instantiated.

[0037] The websocketservermanager class has the following methods: creating a SOCKET and listening, closing a SOCKET, establishing a new connection, disconnecting, sending data, and receiving data.

[0038] Alternatively, when encapsulating the data to be sent, the data can be encapsulated in the following string format:

[0039] “$CT Type, device model, 1, data content, <cr> <lf>"

[0040] In the above string format, the type is the uppercase English abbreviation of the data type in the sending list (such as EDD for engine data); the device model is the model of the device corresponding to the data; and the data content is the specific content of the data to be sent. If the data content field contains multiple data, the data is arranged in a fixed order, and each data is separated by a comma, for example, the rotation speed, the oil pressure, the water temperature, and the like.

[0041] S2, the terminal device accesses the network where the generator set controller is located, and requests the initialized WEBSERVER to obtain the HTML login page and JS script of the generator set controller through the HTTP protocol, logs in, and connects to the initialized WEBSOCKETSERVER to send a WEBSOCKET connection request to the generator set controller.

[0042] The WebSocket is a new persistent protocol under HTML5, which stipulates a communication specification. Through a handshake mechanism, a connection similar to TCP can be established between the client and the server, so as to facilitate the communication between them. It realizes full-duplex communication between the browser and the server, can better save server resources and bandwidth, and achieves the purpose of real-time communication.

[0043] In a feasible implementation, HTML (Hyper Text Markup Language) and JS (JavaScript, a lightweight, interpreted or just-in-time compiled programming language with function priority) are deployed in the NAND (Non-volatile Memory Device) of the generator set controller in advance. When the terminal device accesses the network where the generator set controller is located, it can access the network where the generator set controller is located through wired, wireless or routing.

[0044] After accessing the network, the terminal device opens the browser, inputs the address of the generator set controller in the browser for sending. In this way, the browser can send an acquisition request based on the HTTP protocol to the WEBSERVER. The acquisition request at least includes the Web name and port number in the URL (Uniform Resource Locator) of the login page of the generator set controller and other information. After receiving the acquisition request, the WEBSERVER sends the HTML login page and JS script of the generator set controller to the terminal device.

[0045] The terminal device receives and displays an HTML login page of the generator set controller, a user can input user information through the HTML login page displayed by the terminal device to log in, and after successful login, automatically connects to the WEBSOCKET SERVER.

[0046] S3, after the generator set controller receives the WEBSOCKET connection request of the terminal device, establishes a new connection and listens.

[0047] Optionally, the step of establishing a new connection and listening in S3 can include steps S31-S34.

[0048] S31, after the generator set controller receives the WEBSOCKET connection request of the terminal device, saves the WEBSOCKET descriptor to establish a new connection.

[0049] S32, insert the WEBSOCKET descriptor of the new connection into the HASH table to maintain multiple connections at the same time.

[0050] Wherein, the HASH table is established with IP address and port as key value, so as to facilitate the search.

[0051] S33, listen to whether there is new message to the new connection.

[0052] S34, listen to whether the new connection is disconnected, if disconnected, remove the descriptor of the new connection from the HASH table.

[0053] S4, the generator set controller sends the required data of the page in the sending list to the WEBSOCKET according to the different HTML pages currently browsed by the WEBSOCKET.

[0054] In a feasible implementation, different HTML pages can be divided into monitoring pages and other pages, if the currently browsed page is a monitoring page, the generator set controller determines the required data of the monitoring page in the sending list, and sends the required data to the new connection once a second, to ensure the real-time of the monitoring page; if the currently browsed page is other page, the real-time of the page does not need to be considered, therefore, the generator set controller determines the required data of the page in the sending list, and only sends the required data once when the connection is established.

[0055] Wherein, the required data of the monitoring page includes generator data, load data, mains data, engine data, state indication data and version data; the required data of other pages can include configuration data, version data and historical data according to the display content of different pages.

[0056] S5, if the page currently browsed by the WEBSOCKET is the quick guide or the generator set configuration page, a general statement is sent to the generator set controller to modify the parameters of the generator set controller.

[0057] In an available implementation, when the user wants to modify the generator set controller through the terminal device, the quick guide or the generator set configuration page can be browsed through the terminal device, and the quick guide or the generator set configuration page is a page set by the user in advance, so that when the WEBSOCKET identifies that the page currently browsed is the quick guide or the generator set configuration page, the general statement can be actively sent to the generator set controller.

[0058] Optionally, the general statement can include a timer setting, an engine setting, a generator setting, a mains setting, a load setting, a switch setting, an input port setting, an output port setting, a sensor setting, a basic setting, and a maintenance setting.

[0059] Optionally, the string format of the general statement can be as follows:

[0060] " $-- configuration type, device model, 1, parameter content, <cr> <lf>"

[0061] The configuration type is written in lowercase English (e.g., engine is set to edd). If the parameter content contains multiple parameters, the parameters are arranged in a fixed order, and each parameter is separated by a comma, for example: engine type, number of engine teeth, rated speed, ...

[0062] After receiving the general statement, the generator set controller modifies the corresponding parameters according to the configuration type and parameter content in the general statement.

[0063] Optionally, S2 to S5 can be repeated to establish multiple connections to access the generator set controller simultaneously.

[0064] In one feasible implementation, multiple terminal devices can simultaneously access the generator set controller, such as... Figure 2 The flowchart shown ( Figure 2 In this document, the generator set controller is abbreviated as controller. Device 1, Device 2, ..., Device n can simultaneously establish a connection with the generator set controller. The connection establishment process of each terminal device can refer to the above steps S2 to S5, which will not be elaborated here.

[0065] This invention enables communication between the generator set controller and the network terminal via WEBSOCKET. Users can connect and access the network anytime, anywhere using any network-enabled terminal device, without needing to install any specific application. This greatly simplifies the steps and conditions required to establish communication and improves communication efficiency. Furthermore, multiple connections can be established simultaneously within the same network, further enhancing work efficiency. The invention combines the advantages of long communication distance, high speed, and large data volume with the advantages of simple operation, low latency, reliable connection, and low cost. It is scientifically sound, practical, and highly adaptable to various environments.
