The wireless communication module is connected with a main control chip which is connected with a temperature sensor, a memory, a pressure / water quality sensor, a tape-control low-power voltage regulator, a self-perpetuating relay, a single-bus communication port and a low-power voltage regulator, the low-power voltage regulator is connected with the memory, the self-perpetuating relay is connected with the wireless communication module and an SIM card of the wireless communication module, and a battery pack provides a power supply for various electric appliances. The invention has reasonable structure, adopts battery power, does not need commercial power support and has good working effect.

Description

Technical field: [0001] The invention relates to a battery-powered wireless real-time monitoring terminal. Background technique: [0002] The existing water supply network monitoring system under construction cannot meet the daily needs of the water company due to the defect of the remote transmission terminal. The terminals used are mainly divided into two categories: [0003] The first type is the traditional RTU, which transmits data through a radio station. The terminal has the following disadvantages: [0004] Difficulty in selecting points: At present, the pipeline network monitoring system uses radio stations to collect remote data, such as pipeline network pressure, flow, water quality and other parameters. The data transmission of the radio station has the problem of high power consumption, and must use 220V mains power; wireless signal data transmission is also a major problem that the traditional radio station is difficult to deal with. It is necessary to install...

AI Technical Summary

Problems solved by technology

[0008] High construction cost: According to the different physical quantities measured, the direct cost of a monitoring station construction is estimated to need 100,000-200,000 yuan, which does not include the cost of human resources

[0009] The second type of communication terminal has been developed in recent years and mainly uses GPRS or CDMA communication. Although this system solves the communication problem, the real-time communication and power supply problems have not been solved well.

Local pressure is too high or low due to insufficient control of pipe network pressure

If the pressure is too high, the power consumption will increase, the loss of pipe network equipment will be greater, and the probability of pipe burst will increase significantly; if the pressure is too low, the water will not be delivered to users, which will cause a lot of inconvenience to urban residents.

Therefore, all water companies will adjust the pressure to a high level, preferring to lose power consumption to send water out, which will indirectly cause a situation where the more water is supplied, the more serious the loss will be.
