In order to more integrally and completely understand the communication protocol conversion method provided in the embodiment of the present application, please refer to fig. 6 and fig. 7, in the following, a protocol conversion device is taken as an SNMP protocol converter, a first conversion communication device includes a serial port communication device and an ethernet communication device, and a second conversion communication device is taken as an SNMP communication device for example, and the communication protocol conversion method includes the following steps:

s11, the serial port communication device is connected with the SNMP protocol converter in a serial port communication mode, and/or the Ethernet communication device is connected with the SNMP protocol converter in an Ethernet communication mode;

s12, the upper computer obtains the conversion configuration data through the configuration operation of the user on the protocol conversion configuration client and sends the data to the SNMP protocol converter; the protocol conversion configuration client can comprise different configuration modes such as an application program client, a webpage client, an applet and the like; the upper computer can load a protocol conversion configuration client at will and provide an intelligent terminal for user configuration operation, such as a mobile phone, a personal computer and the like.

S13, the SNMP protocol converter obtains and stores the conversion configuration data from the upper computer; the conversion configuration data includes but is not limited to communication protocol, object identifier, data type, read-write attribute, and incidence relation between object identifier and communication protocol register address, and the conversion configuration data can be adjusted based on actual application requirement;

s14, the SNMP communication device reads the data value of the object identifier from the SNMP protocol converter through the SNMP protocol, and indirectly obtains the data value of the address of the communication protocol register needing to be converted according to the incidence relation, so as to realize the conversion between the SNMP protocol and the communication protocol needing to be converted.

If the communication protocol needing to be converted is a serial communication protocol, the communication protocol is configured in a serial mode, the upper computer is connected with the SNMP protocol converter through a serial port on hardware, a configuration client is opened on the upper computer, the communication protocol needing to be converted into the SNMP protocol is selected to be the serial communication protocol through a visual interface, and OID information of the serial communication equipment is filled, for example: and storing the configured information into the SNMP protocol converter in a serial port mode after the configuration is finished, wherein the OID data type, the OID read-write attribute, the mapping relation between the OID and the serial port communication protocol data and the like. In a specific example, the communication protocol to be converted can be selected as a Modbus-RTU serial port protocol by configuration operation, an OID1 information is filled, the data type is integer, the read-write attribute is read-only, the mapping relationship is that the OID1 is associated with the Modbus-RTU register address 0, the SNMP protocol converter reads the data of the register address 0 of the serial port communication equipment through the Modbus-RTU protocol, the read register value is stored in the SNMP protocol converter, and the register value is taken as the data value of the OID1, so that the SNMP communication equipment can read the data value of the OID1 through the SNMP protocol, indirectly obtain the data value of the Modbus-RTU protocol register address 0 of the serial port communication equipment, and the conversion between the serial port communication protocol and the SNMP protocol can be achieved.

For another example, if the communication protocol to be converted is an ethernet communication protocol, the communication protocol is configured in an ethernet manner, the upper computer is connected to the SNMP protocol converter through the ethernet on hardware, and opens the web client at the upper computer, and selects the communication protocol to be converted into the SNMP protocol on the web visual interface by accessing the IP address of the SNMP protocol converter, and fills in OID information, for example: and the OID data type, the OID read-write attribute, the mapping relation between the OID and the data of the communication protocol to be converted and the like, and after the configuration is finished, the configured information is stored into the SNMP protocol converter 3 through the Ethernet. In a specific example, the configuration operation may include selecting the communication protocol to be converted to be a Modbus-TCP serial port protocol, filling in an OID1 information, where the data type is an integer, the read-write attribute is read-only, the mapping relationship is that the OID1 is associated with the Modbus-TCP register address 0, the SNMP protocol converter reads the data of the register address 0 of the ethernet communication device 1 through the Modbus-TCP protocol, the read register value is stored in the SNMP protocol converter 3, and the SNMP communication device 4 may read the data value of the OID1 through the SNMP protocol to indirectly obtain the data value of the Modbus-TCP protocol register address 0 of the ethernet communication device 1, so as to achieve conversion between the ethernet communication protocol and the SNMP protocol.
