Flame-proof intrinsic safe type multiprotocol converter

The utility model provides a flame-proof intrinsic safe type multiprotocol converter which includes an embedded system, a communication module, and a power supply, and is characterized in that the embedded system includes a built-in program memory, an external data memory, a CPU, a real-time clock module, a button module, and a display module, and the communication module includes a communication circuit and communication interfaces which are corresponding to the communication circuit. Through adopting the embedded technology, the on-site communication protocols of different types can be converted, and the main protocols, such as the RS232, the RS485, the TCP/IP, and the CAN, can be converted with one another. At the same time, the multiprotocol converter is flame-proof and intrinsic safe, so the information data seamless transmission among various monitoring systems can be realized. The monitoring systems can be connected with a ring network switch, so the device states and parameters can be timely transmitt
