Embodiment

[0023] A kind of wireless terminal equipment based on GPRS network, its structural diagram is as attached figure 1 As shown, it mainly includes the following parts: GSM module, STM32 microcontroller, power module, RS232 serial port, RS485 serial port, status indicator, button, SIM card slot, suction cup antenna and shell. Among them, the GSM module is powered by the power module, and the GSM module is connected to the SIM card slot to communicate with the placed SIM card. The GSM module needs to be connected to the suction cup antenna to ensure stable signal quality. The GSM module is connected to the status indicator to detect the module. In the working state, the STM32 MCU communicates with the GSM module through the serial interface. The STM32 MCU uses the power supply module for power supply. The STM32 MCU connects to the RS485 serial port and the RS232 serial port to communicate with the terminal equipment. In the working state, the STM32 MCU connection button is used to ...

Abstract

The invention belongs to the technical field of communication and discloses wireless terminal equipment based on a GPRS network and a wireless data transmission method. According to the wireless terminal equipment, a TCP/UDP/HTTP protocol is embedded into DTU of GPRS, supporting three working modes: network unvarnished transmission, HTTP and short message unvarnished transmission. In the network unvarnished transmission mode, communication between the remote terminal equipment and a remote server can be established, in the HTTP mode, the remote terminal equipment can require a remote HTTP server by way of GET or POST requiring mode, and in the short message unvarnished transmission mode, short message data transmission can be carried out between the remote terminal equipment and a mobile phone terminal directly.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a wireless terminal device and a wireless data transmission method based on a GPRS network. Background technique [0002] With the rapid development of science and technology, how to efficiently, quickly, stably and safely transmit data to achieve functions such as remote data collection and remote control has become an urgent problem that many industries need to solve. For example, traditional wireless communication technologies such as Zigbee, WIFI and 2.4G are weak in long-distance data transmission and are not easy to install. In today's big data communication, one-to-one communication can no longer keep up with the development needs of the times, and one-to-many or many-to-many communication has become an inevitable demand of the industry. [0003] Although there are many GSM modules on the market, these modules must be redeveloped before they can be used ...
