Problems solved by technology

For example: Data communication over telephone lines is very common, but many aspects of this communication line are not satisfactory: strings and disconnections occur from time to time, and the low transmission rate makes data transmission difficult, especially when the line is busy. It is also a headache; for data communication through digital transmission stations, it is necessary to apply for a dedicated channel, which is not only expensive, but also in urban high-rise and high-interference environments, the channel is susceptible to interference. At the same time, this method is not easy to achieve cross-city / regional monitoring and data transmission; apply Bluetooth wireless transmission technology, although its transmission effect is better, but the maximum transmission distance is very short (only about 10 meters), not suitable for remote monitoring

Abstract

This invention relates to wireless communication and remote control device, which comprises host adapter and terminal adapter communicated through the first and second GSM modules, wherein the host adapter uses the first central processor as core and the said terminal adapter uses the second CPU as adapter as core connected to the second GSM module and to the outer control circuit trough the third series level converter. The second CPU is separately connected to the second watchdog and power module.

Description

technical field [0001] The invention relates to a wireless communication and remote monitoring device, in particular to a wireless communication adapter for remote complex monitoring. Background technique [0002] In recent years, with the improvement of the national economy and the development of science and technology, especially the advent of the information age, fast communication methods have provided a powerful tool for improving industrial production technology and management levels, improving work efficiency, reducing labor intensity, reducing staff and increasing efficiency. Support, leading all walks of life to gradually embark on the track of informatization, networking, and intelligent management. [0003] Although there are many means of communication at present, both wired and wireless methods are widely used in many fields. In terms of remote monitoring, the commonly used communication methods have their own advantages and disadvantages. For example: Data co...
