Background
The field bus communication system is increasingly widely used in industrial production and automation technology. The fieldbus is a communication network between plant floor devices. The field-set execution user equipment, such as a numerical control device, a servo driver, an I/O module, a sensor and the like, are interconnected through a field bus to form a networked, digital, fully-open and fully-distributed automatic control system.
Protocol gateways typically perform protocol conversions between network regions using different protocols. This conversion process may occur at layer 2, layer 3 or between layers 2, 3 of the OSI reference model. However, there are two protocol gateways that do not provide the translation function: a security gateway and a pipeline. Due to the logical difference of the two interconnected network areas, the security gateway is a necessary intermediary between the two technically similar network areas.
The protocol conversion device in the prior art has a simple structure and limited realized functions, and cannot watch the transmitted data.

Further, the controller stores the data of each serial interface after receiving the data, and when the controller receives an inquiry command, a check command and a deletion command input by a user at the mobile terminal, the controller performs inquiry, check and deletion operations on the stored data.
Further, the controller is also connected with a 4G communication module.
Furthermore, the equipment connected with each serial interface sends a heartbeat message to the corresponding serial interface at a set time interval; when the serial interface does not receive the heartbeat message of the equipment within the set time, the equipment connected with the serial interface is judged to be offline and is sent to the mobile terminal.
Further, when data is displayed on the mobile terminal, if the time length of pressing the data is detected to be greater than a first set time length, a link of the data is opened, and if the time length of pressing the data is detected to be greater than a second set time length, an operation menu of the data is popped up.
According to the technical scheme provided by the invention, the mobile terminal is in communication connection with the controller of the protocol conversion device body, the controller sends the data received by each serial interface to the mobile terminal, and a user can display the data of equipment connected with each serial interface on the mobile terminal and input an instruction, so that the problem of single function of the communication conversion equipment in the prior art is solved.

Fig. 1 is a schematic structural diagram of a communication protocol conversion apparatus according to an embodiment of the present invention.
Detailed Description
The embodiment provides a communication protocol conversion device, which is used for solving the problem that the function of communication protocol conversion equipment in the prior art is single.
The communication protocol conversion device provided in this embodiment, taking an application thereof in a motor detection system as an example, is structurally shown in fig. 1, and includes a mobile terminal and a communication protocol conversion device body, where the communication protocol conversion device body includes a controller, and the controller is connected with a WIFI module, a CAN bus module, and four serial interfaces.
Each serial interface is respectively used for communicating with a motor controller of the motor, the WIFI module and the CAN bus module are used for connecting a server, and the controller receives working state data of the corresponding motor from each serial interface and sends the working state data to the server through the WIFI module and the CAN bus module.
The mobile terminal adopts a mobile phone and is in communication connection with the controller, the communication connection can be Bluetooth communication connection, namely a Bluetooth module is arranged on the communication conversion device body, and the controller is connected with the Bluetooth module; the mobile terminal is also provided with a Bluetooth module so as to establish communication connection between the mobile terminal and the controller; the controller and the mobile terminal can be in communication connection in other modes, if the controller is in communication connection with the internet through the WIFI module, the mobile terminal is connected with the internet through the GPRS communication module, and therefore communication connection between the controller and the mobile terminal is established through the internet.
The mobile terminal is provided with a touch screen and is provided with an application program, and when the application program comprises a virtual keyboard and a display panel. When the controller of the communication conversion device body receives the permission data of each motor through each serial communication interface, the permission data is stored.
The user inputs instructions including a query instruction, a check instruction and a delete instruction through the virtual keyboard.
When a user inputs a query instruction, the mobile terminal sends the query instruction to the controller, and the controller sends corresponding data to the mobile terminal; the mobile terminal receives the data sent by the controller and then displays the data on the display panel;
when a user inputs a checking instruction, the mobile terminal sends the checking instruction to the controller; the checking instruction is an instruction for checking whether the motor data is abnormal or not, the controller receives the checking instruction and judges whether the motor data is abnormal or not, and the checking result is sent to the mobile terminal; the mobile terminal receives the checking result sent by the controller and then displays the checking result on the display panel;
