The method comprises the following steps:
s1, the generator set controller initializes WEBSERVER and WEBSOCKETSERVER, and encapsulates data to be sent into a sending list according to a preset format.
The chinese name of WEBSERVER is called a web server or a web server, and may parse an HTTP (Hyper Text Transfer Protocol) Protocol, so that the WEBSERVER may be used to process an HTTP request. Webscocketserver may be used to send data, respond to general statements, and respond to query statements.
Wherein the routing list may include status indication data, timer data, engine data, sensor data, utility data, power generation data, load data, alarm data, input port data, output port data, history data, version data, and configuration data.
In a possible implementation manner, after initializing WEBSERVER and WEBSERVER, the generator set controller may wait for a connection request of the terminal device, and optionally, the method for initializing WEBSERVER and WEBSERVER in S1 may be as follows:
an object my _ websocket of the websocket server class is defined and instantiated.
The websocket server manager comprises the following steps: creating a SOCKET and listening, closing the SOCKET, establishing a new connection, disconnecting the connection, sending data and receiving data.
Optionally, when encapsulating the data to be transmitted, the data may be encapsulated according to the following string format:
"$ CT type, device model, 1, data content, < CR > < LF >".
In the above character string format, the type is an abbreviation of capital english of the data type in the transmission list (for example, the engine data is EDD); the equipment model is the model of the equipment corresponding to the data; the data content is the concrete content of the data to be sent, if the data content field contains a plurality of data, the data are arranged according to a fixed sequence, and each data is separated by commas, such as rotating speed, oil pressure, water temperature … ….
And S2, the terminal equipment accesses a network where the generator set controller is located, acquires an HTML login page and a JS script of the generator set controller through the initialized WEBSERVER requested by the HTTP protocol, logs in, is connected to the initialized WEBSOCKETSERVER, and sends a WEBSOCKET connection request to the generator set controller.
The WebSocket is a new persistent protocol under HTML5, which appoints a communication specification, and a connection similar to tcp can be established between a client and a server through a handshake mechanism, so that the communication between the client and the server is facilitated. The full-duplex communication between the browser and the server is realized, the server resource and the bandwidth can be better saved, and the purpose of real-time communication is achieved.
In a possible implementation manner, both HTML (Hyper Text Markup Language) and JS (JavaScript, a lightweight, interpreted, or just-in-time compiled programming Language with function priority) are deployed in advance in a NAND (Non-volatile Memory Device) of the generator set controller, and when a terminal Device accesses a network where the generator set controller is located, the terminal Device may access the network where the generator set controller is located in a wired, wireless, or routing manner.
After the access network, the terminal device opens the browser, and inputs the address of the generator set controller in the browser for sending, so that an acquisition request can be sent to the WEBSERVER through the browser based on the HTTP protocol, where the acquisition request at least includes information such as a Web name and a port number in a URL (Uniform Resource Locator) of a login page of the generator set controller, and after receiving the acquisition request, the WEBSERVER sends the HTML login page and the JS script of the generator set controller to the terminal device.
The terminal equipment 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 equipment to log in, and the user is automatically connected to WEBSOCKETSERVER after the login is successful.
And S3, after the generator set controller receives a WEBSOCKET connection request of the terminal equipment, establishing new connection and monitoring.
Optionally, establishing a new connection and listening in S3 may include the following steps S31 to S34:
and S31, after the generator set controller receives a WEBSOCKET connection request of the terminal equipment, storing a WEBSOCKET descriptor to establish new connection.
S32, inserting WEBSOCKET descriptors of the new connection into the HASH table so as to maintain a plurality of connections simultaneously.
The HASH table is established by taking the IP address and the port as key values, so that the lookup is convenient.
S33, monitoring whether a new message comes in the new connection.
S34, monitoring whether the new connection is disconnected, and if the connection is disconnected, removing the descriptor of the new connection from the HASH table.
And S4, the generator set controller sends data required by the page in the sending list to the WEBSOCKET according to different HTML pages browsed currently by the WEBSOCKET.
In a feasible implementation manner, different HTML pages can be divided into two types, namely a monitoring page and other pages, if the currently browsed page is the 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 per second to ensure the real-time performance of the monitoring page; if the current browsed page is other pages, the real-time performance of the page does not need to be considered, so that the generator set controller determines the data required by the page in the sending list and only sends the required data once when the connection is established.
The required data of the monitoring page comprises generator data, load data, commercial power data, engine data, state indication data and version data; the required data of other pages can comprise configuration data, version data and historical data according to the display content of different pages.
And S5, if the page browsed by the WEBSOCKET currently is a quick guide page or a unit configuration page, sending a general statement to the generator set controller to modify the parameters of the generator set controller.
In a possible implementation manner, when a user wants to modify the generator set controller through the terminal device, the user can browse a quick wizard or a unit configuration page through the terminal device, where the quick wizard or the unit configuration page is a page preset by the user, and thus, when the web browser recognizes that the currently browsed page is the quick wizard or the unit configuration page, the user can actively send a general sentence to the generator set controller.
Optionally, the universal statement may include a timer setting, an engine setting, a generator setting, a utility setting, a load setting, a switch setting, an input port setting, an output port setting, a sensor setting, a base setting, and a maintenance setting.
Alternatively, the string format of the universal sentence may be as follows:
"$ -configuration type, device model, 1, parameter content, < CR > < LF >".
The configuration type is a form written in lower case english (for example, the engine is set to edd), if the parameter content includes a plurality of parameters, the parameters are arranged according to a fixed sequence, and each parameter is separated by a comma, for example: engine type, number of engine teeth, rated speed, … ….
And after receiving the general statement, the generator set controller modifies the corresponding parameters according to the configuration type and the parameter content in the general statement.
Optionally, S2 to S5 are repeatedly performed, establishing a plurality of connections while accessing the genset controller.
In a feasible implementation manner, a plurality of terminal devices may access the generator set controller at the same time, as shown in the flow diagram of fig. 2 (the generator set controller is abbreviated as a controller in fig. 2), the device 1, the device 2, the device … …, and the device n may establish a connection with the generator set controller at the same time, and the connection establishment process of each terminal device may refer to the above steps S2 to S5, which is not described herein again.
