Remote meter reading system based on RF and GPRS radio network

Abstract

The invention relates to a remote information acquisition system, in particular to a remote meter reading system based on RF and GPRS wireless networks. The invention comprises a wireless digital transmission meter arranged indoors, a relay concentrator and a remote monitoring center arranged in communities or buildings. The wireless digital transmission meter transfers data in a wireless way through an RF module and the relay concentrator. The relay concentrator receives the data uploaded by the wireless digital transmission meter through the RF module, and communicates data with the remote monitoring center through the GPRS module. Monitoring and control centers of water supply, power supply or natural gas companies just need to be equipped with central station machines with internal antennae. A gathering point, such as a community, just needs to be equipped with a relay concentrator. Accordingly, the construction cost of the system is low. Water supply, power supply, natural gas companies or property management departments of communities grasp information about water consumption, power consumption, charging of users and so on in time and accurately by detecting and reading meters automatically by the system. In this way, the management and the service of the companies are improved.

Description

Technical field [0001] The invention relates to a remote information collection system, in particular to a remote meter reading system based on RF and GPRS wireless networks. Background technique [0002] Because users work outside during the day, traditional manual meter reading generally uses morning, evening and weekend meter reading to improve meter reading efficiency, but even so, about 10% of users cannot read meters and deliver bills in time. It affects residents' water and electricity consumption, so the quick and convenient remote meter reading is welcomed by the majority of residents. [0003] For many years, the communication of the wireless remote meter reading system generally adopts the radio station. If this kind of communication method is adopted, the monitoring centers of water supply companies and power supply companies need to be equipped with radio stations, dedicated power supplies and high-gain iron tower antennas. A high-gain directional antenna need...

AI Technical Summary

Problems solved by technology

If this kind of communication method is adopted, the monitoring centers of water supply companies and power supply companies need to be equipped with radio stations, dedicated power supplies and high-gain iron tower antennas. A high-gain directional antenna needs to be configured, the cost of remote meter reading is high, and it is not conducive to maintenance

Some remote meter reading systems use wired methods and need to lay lines. It is difficult to renovate in old houses, and the remodeling cost is high and the remodeling time is long.
