Abstract

The invention discloses a multi-protocol converter based on GSM (Global System for Mobile Communications) short message transmission in a wireless communication network, and in particular relates to a device for converting a protocol (such as Modbus / PROFIBUS (PROcess Field Bus) protocol) into a protocol for GSM short message transmission in the wireless communication network and realizing a network protocol converting function for two-way transmission of remote data, relating to the technical field of remote network connection. The multi-protocol converter comprises a main controller component, a wireless receiving and transmitting component, an LED drive circuit, a keyboard, a protective circuit and an operating power supply, wherein the main controller component is an STC12C5A16S2 module, and the wireless receiving and transmitting component is a TC35i module. Due to the procedures of initialization of the microprocessor STC12C5A16S2 module including a main program, initialization of the TC35i module, sending SMS (Short Messaging Service) short messages, interrupting receiving SMS (Short Messaging Service) short messages and the like, the two-way transmission of the remote data is realized in the real sense, and the system design is simplified, thus the system construction cost and the maintenance cost are reduced.

Description

Technical field [0001] The present invention relates to the technical field of remote network connection, and specifically refers to the conversion of a protocol (such as Modbus / PROFIBUS protocol) into another protocol for transmission of GSM short messages in a wireless communication network, which has a relay function for accomplishing two-way transmission of remote data Network protocol conversion function equipment. Background technique [0002] At present, there are two types of remote monitoring systems. One is that there is no on-site monitoring system at the production site, but the data is collected and sent directly to a remote computer for processing; the other is that on-site monitoring and remote monitoring coexist, generally using fieldbus technology Connect the sensors and monitoring equipment distributed in each device. The advantages of the remote monitoring system are: with the help of remote monitoring, the internal information network (Intranet) of the enterp...
