Remote monitor device for grouping data transfer water supply pipe network pump station

Abstract

The invention relates to a remote detector of grouped data transmission water tube network pump station, wherein it provides one GPRS detecting station which can be increased via need; the GPRS detecting station has simple address selection, simple installment and low cost, to realize online detected grouped data transmission water tube network pump station. The invention comprises water tube network remote detection distributor and area pump station detector, while the first one has tube network remote terminal, tube network wireless GPRS network, and APN special-wire network, and distributor, and the area pump station detector has pump station terminal, pump station detecting center and pump station wireless GPRS network.

Description

technical field [0001] The invention relates to a remote measurement and control device, in particular to a remote measurement and control device for group data transmission of water supply pipe network pumping stations. Background technique [0002] The existing water supply network remote monitoring and dispatching system adopts digital wireless data transmission station (referred to as digital transmission station) communication mode, and each pipe network detection station only provides 1 channel of analog data (pipe network pressure), and the upper computer uses VB to carry out Programming, the radio station at the control center performs one-to-one "polling" data collection for all stations (for example, 42 stations) within a specified time. [0003] The digital transmission station is a wireless data transmission station with functions such as forward error correction and equalized soft judgment, which adopts digital signal processing and digital modulation and demodu...

AI Technical Summary

Problems solved by technology

The polling mode and coverage of the data transmission station determine that the capacity of the network has a certain limit, and the number of detection stations cannot be increased indefinitely

[0006] 2. The high power of the equipment is not conducive to installation in remote places

The transmission power of digital radio stations is generally 25W in industrial applications. This feature determines that the application of digital radio stations can only be limited to a certain area, which is not conducive to installation in remote places.

[0007] 3. High construction and operation costs

The existing system only provides one channel of analog data (pipe network pressure), which cannot better reflect the operation of the equipment on site

[0010] 5. Seriously affect data transmission when disturbed

When the number of pumping stations increases, the problem of not being able to respond to the on-site operation in a timely manner becomes more prominent

[0013] 2) The labor intensity of the staff on duty is high

Therefore, it is necessary for the personnel on duty to dial continuously to understand the operation status of each pump station. The labor intensity of the personnel on duty is high, and the spirit is in a state of high tension, which makes the personnel on duty easy to get tired

[0014] 3) High operating and management costs
