Data communication method of mobile terminal as well as mobile terminal and communication system thereof

Abstract

The invention relates to a data communication method of a mobile terminal as well as the mobile terminal and a communication system thereof. The data communication method of the mobile terminal adopts a data frame mode to communicate with a gateway server at the mobile terminal, and a data frame comprises a frame header, a frame length, an instruction code, a device number, a plurality of data items and a checksum in sequence; the mobile terminal wirelessly communicates with the gateway server through a set communication module. Through designing a specific communication protocol for the mobile terminal equipment and making the communication protocol method conform to the actual usage condition of the mobile terminal equipment completely, the mobile terminal equipment can communicate with the gateway server through GPRS (General Packet Radio Service), so that daily monitoring of goods, tracking and query after loss, abnormal dismantling alarm and low power alarm are realized; the communication protocol method has an error correction function, so that the correct transmission of the data is guaranteed, and the communication protocol method is concise and is convenient for expansion of the data function.

Description

technical field [0001] The present invention relates to the communication field, and more specifically refers to a mobile terminal data communication method, a mobile terminal and a communication system thereof. Background technique [0002] At present, logistics and transportation are becoming more and more developed. When the goods are lost, in the traditional method, the owner of the goods can only contact the person in charge of the transportation to recover the lost goods. The cost is high, the difficulty is high, and the possibility of recovery is low. With the Internet With the development of the market, there are some tracking devices on the market. The data communication methods of such devices are complicated. At present, there are many data communication protocol methods, most of which are a complete set of protocol methods. The structure and definition are complicated, resulting in the complexity of data processing and programming Therefore, these various communi...

[0002] At present, logistics and transportation are becoming more and more developed. When the goods are lost, in the traditional method, the owner of the goods can only contact the person in charge of the transportation to recover the lost goods. The cost is high, the difficulty is high, and the possibility of recovery is low. With the Internet With the development of the market, there are some tracking devices on the market. The data communication methods of such devices are complicated. At present, there are many data communication protocol methods, most of which are a complete set of protocol methods. The structure and definition are complicated, resulting in the complexity of data processing and programming Therefore, these various communication protocols are suitable for complex systems such as vehicle equipment, but for a single piece of goods, such devices are not suitable
