[0004] Invention content: To solve the above technical problems, the present invention adopts the following technical solutions: an online information flow intelligent gateway communication control method, comprising the following steps:

[0005] S1, the main program starts and performs initialization settings;

[0006] S2, determine whether the program communication is on or off, and proceed as follows:

[0007] When judging the open state,

[0008] (1) The communication host receives the serial communication data packet and combines the host address data through the Port-Task;

[0009] (2) obtaining slave information, wherein the slave information includes: a collection address, a feature code, and a length code; and storing the slave information in a database and sending it to the next slave;

[0010] (3) After receiving the information from the previous master, the next slave repeats steps (1) and (2) until the last slave completes the data update and transmits it back to the Can end for processing;

[0011] When the interruption status is determined, after the data is interrupted, the data interruption information is cleared; and the data request is sent again. After the host agrees to receive the data, it is returned to the host, and the host determines the start or interruption status and returns to step (1);

[0012] S3, after processing, the host Can returns to the main program to exchange data.

[0013] Furthermore, the parameters initialized in step S1 include Ethernet address, host and slave serial ports, and CAN bus.

[0014] Beneficial effects: Compared with the prior art, the present invention realizes the function of managing the communication of various sensors and multiple intelligent auxiliary devices; it has the device communication of multiple control units and TCP / IP and MODBUS-RTU upload functions, which can realize the control logic and realize the control communication output according to the needs. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with specific examples. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, modifications to various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the appended claims of the present application.

[0016] The online information flow intelligent gateway communication control method of the present invention, the control system defaults port1, port2 serial ports as Modbus slave stations, port3 port as CanBus bus interface, port4, port5 serial ports as Modbus master stations, can simultaneously access two dynamic ring systems, responsible for forwarding Port1 ~ Port3 ports to collect various types of data; and at the same time has the Ethernet interface (RJ45) server-side function, responsible for the corresponding TCP / IP Modbus protocol client access request. The specific steps are as follows:

[0017] S1, the main program starts and performs initialization settings;

[0018] S2, determine whether the program communication is on or off, and proceed as follows:

[0019] When judging the open state,

[0020] (1) The communication host receives the serial communication data packet and combines the host address data through the Port-Task;

[0021] (2) obtaining slave information, wherein the slave information includes: a collection address, a feature code, and a length code; and storing the slave information in a database and sending it to the next slave;

[0022] (3) After receiving the information from the previous master, the next slave repeats steps (1) and (2) until the last slave completes the data update and transmits it back to the Can end for processing;

[0023] When the interruption status is determined, after the data is interrupted, the data interruption information is cleared; and the data request is sent again. After the host agrees to receive the data, it is returned to the host, and the host determines the start or interruption status and returns to step (1);

[0024] S3, after processing, the host Can returns to the main program to exchange data.

[0025] The parameters initialized in step S1 of the present invention include Ethernet address, host and slave serial ports, and CAN bus. The control system defaults to the distributed device access bus serial port number and serial bus address, and pre-reads the corresponding external communication cache address through a predetermined rule (as shown in Table 1 below). After the gateway is requested, it performs centralized data conversion and transmission.
