Dual network monitoring system based on zigbee and gprs

Abstract

The invention relates to a dual-network monitoring system based on ZigBee and GPRS, which is characterized in that it includes: a class of client, including a client main control module and a positioning module electrically connected thereto, a client ZigBee module and a client bluetooth module; a monitoring terminal , including monitoring the main control module and its electrical connection monitoring Bluetooth module and monitoring ZigBee module; the client also includes a detection module with a built-in sensor, the system works in such a dual network: the client / monitoring end first searches for a GPRS gateway device with Bluetooth Access to the GPRS network, and access to the ZigBee network without a GPRS network; when the client accesses the GPRS network, it regularly sends out its current location data and the location data stored regularly when it is not connected to the GPRS network. This dual-network monitoring system, with the help of mobile phone and GPRS network, meets the positioning search in various complex situations such as earthquake relief and disaster relief, and realizes monitoring without blind spots.

Description

technical field [0001] The invention relates to monitoring, earthquake relief and location search, in particular to a dual-network monitoring system based on ZigBee and GPRS. Background technique [0002] With the development of Internet and electronic communication technology, the spatial positioning technology based on GPRS network has been developed and applied rapidly. Almost all cars are equipped with a satellite navigation system, and some buses are also equipped with a satellite tracking system. The global positioning system (GPS) or Beidou navigation module on the car transmits the geographical location information to the monitoring room through the GPRS network to facilitate vehicle monitoring. Scheduling and real-time monitoring. The satellite positioning system based on GPRS and GPS has also been vigorously developed in the field of personal monitoring. The elderly or children wear a miniaturized GPS module, and transmit the geographical location information to t...

AI Technical Summary

Problems solved by technology

Although it is theoretically impossible to search for locations where there is no GPRS signal, the current GPRS network has been widely covered, so it is completely suitable for most situations

However, in the face of natural disasters, when the GPRS network and equipment are attacked and destroyed, the location of the client being searched or monitored cannot be known by the monitoring terminal, making it difficult to locate the target and to carry out the search work

Although the GPRS network can be rebuilt at this time, due to the complex equipment of the GPRS network, it takes a lot of manpower and time to rebuild, but the search and monitoring cannot be delayed.
