The motor is connected to the network adapter 10 via a serial interface. The control end communicates with the network adapter 10 by using a TCP/IP protocol, and configures data including baud rate, data bits, stop bits, parity bits and the like of motors of all ports. After the configuration is completed, the adapter starts to work. The connected motors communicate with each other according to respective protocols, the motor operation data is sent to the network adapter 10, and the central processing unit 16 disassembles and stores the data in the motor operation data into corresponding registers, so that multiple protocol communications in the same network are realized.
The multiple motors are connected and installed on site in a one-level bus structure, and the motor operation data are arranged at different ports according to brands and are stored in groups by the starting address of the power panel. The control end realizes the information monitoring function of the motor by reading the corresponding register in the network adapter 10; the control end writes a specific register in the adapter, and the central processing unit 16 recodes the information to be sent into a protocol transmission frame required by the motor to be controlled and sends the protocol transmission frame to the corresponding motor, so that the control function of the motor can be realized. The grouping motors can be set in batches through a unified master control group number.
It should be noted that the network adapter 10 may convert and encapsulate the received multiple protocol response data into a single protocol, and provide a standard ethernet data interface for the control end. Therefore, the network adapter 10 can realize coexistence communication between the control end and multiple protocols in the same network, and is easy to expand to cover other protocols; the communication program corresponding to the control end can realize standardization, the general applicability of the program is improved, and meanwhile, the debugging time is also reduced. The network adapter 10 can also realize communication between the control end and a plurality of ports, and a plurality of motors at each port are grouped and clustered, so that monitoring and control of a plurality of motors are realized by only one upper computer device such as a PC (personal computer), a server and the like. In addition, the network adapter 10 can simultaneously control the communication of a plurality of ports, each port is connected with wiring in series, the number of the connected motors can reach ten thousands, and the working efficiency is greatly improved.
In an optional embodiment of the present invention, the control end may perform TCP/IP protocol communication by connecting according to the IP address and port number of the network adapter 10; the network adapter 10 determines the configuration of the communication protocol of the relevant motor according to the brand model of the relevant motor connected to the monitoring channel, and the configuration includes data such as baud rate, data bit, stop bit, parity bit and the like of the motor of each port.

In the specific implementation process, a plurality of motors are connected and installed on site in a primary bus structure, and motor information data are arranged at different ports according to brand models and are stored in groups by using the initial addresses of the power panels.
When monitoring the motor, the network adapter 10 receives a TCP/IP protocol command from the control end and then analyzes the command to obtain information to be obtained, and then reads data in a register corresponding to the storage module and encapsulates the data into a TCP/IP protocol specification, and sends the TCP/IP protocol specification to the control end through the ethernet communication module 12; when controlling the motor, the network adapter 10 recodes the data into a protocol transmission frame required by the motor to be controlled according to the motor master control group number and the motor number which are required to be controlled by the rewriting of the relevant register of the control end and the setting command and the parameter of the control end to the motor, and sends the protocol transmission frame to the motor through the serial communication module 14.
It should be noted that, when the motor cluster control is performed, the specific implementation process is similar to the above embodiment, and after the motor group number to be controlled is obtained, the same group is controlled in batch. At this time, only one upper computer device such as a PC and a server is needed to monitor and control the plurality of motors.
Further, when the communication protocol of the motor needs to be modified and expanded, the network adapter 10 is connected with the control end, and then the brand and the model of the motor and the corresponding communication protocol setting are added or modified through programming of the control end, and the configuration data is stored in a corresponding register of the network adapter 10, so that multiple protocol communication in the same network is realized.
