Built-in data transmission terminal based on code division multiple address network

Abstract

An embedded data transmission terminal based on a code division multiple access network comprises a CPU module, a CDMA module electrically connected with the CPU module, an external interface module, a memory module electrically connected with the CPU module, a power supply module electrically connected with the CPU module and the CDMA module and a watchdog circuit electrically connected with theCPU module. The embedded data transmission terminal based on the code division multiple access network provided by the invention is widely applied to the fields of the remote power monitoring, the remote data collection / transmission, the water pollution monitoring, the forest fire prevention, the meteorological data collection, the remote meter reading, the data collection of the environmental protection bureau, etc. and can solve the difficult problem of the data transmission in the wild area without needing any wiring, and the embedded data transmission terminal can provide the wireless data transmission service where a CDMA network exists.

Description

technical field [0001] The invention relates to an embedded data transmission terminal based on code division multiple access network. Background technique [0002] With the continuous development of mobile communication technology, the mobile data communication network using CDMA1x communication mode has covered all parts of the country, and the network is running stably, which brings broad market prospects for industrial applications. Since the application characteristics of various industries are not the same, their requirements for informatization are also different. This requires mobile communication operators to provide industry application solutions that can not only meet the general information communication needs of industry users, but also fully Meet their individual special needs. To this end, in the past two years, China Mobile and China Unicom, the two major mobile communication operators, have been actively carrying out innovative practices in mobile industry ...

AI Technical Summary

Problems solved by technology

[0003] Ordinary CDMA module has some limitations when used, it does not have built-in TCP / IP protocol stack, and needs the user to provide TDP / IP support, that is, it needs to embed TCP / IP in the upper computer system using CDMA module, for ordinary MCU system is a complex and tedious job

Sometimes even more than the workload of the application itself

However, the previous data transmission products are not perfect in terms of performance, processing speed and data capacity, which limits user applications.
