Data acquisition and monitor control system terminal acquisition equipment

Abstract

The invention discloses a terminal collecting device used for a data collecting and monitoring control system. The device comprises a wireless data transmitting unit, a data collecting unit, a central processing unit and an electrical source controlling module. An electrical source output end of an electrical source controlling unit is connected with the data collecting unit and the wireless data transmitting unit; a data input end of the central processing unit is connected with the output end of the wireless data transmitting unit; a data output end of the central processing unit is connected with the wireless data transmitting unit; the central processing unit emits different control signals to the electrical source controlling unit; the electrical source controlling unit turns on / off power for the data collecting unit and the wireless data transmitting unit according to the different control signals. The terminal colleting device of the invention turns on / off power for the data collecting unit and the wireless data transmitting unit by the electrical source controlling unit according to the different control signals, thereby effectively saving power. A battery pack can be adopted as the electrical source to electrify the terminal collecting device, so as to realize data collection of a monitoring point at any position.

Description

technical field [0001] The invention relates to a data collection and monitoring control system, in particular to a terminal collection device of the data collection and monitoring control system. Background technique [0002] In SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) systems such as urban water supply / gas supply, there are a large number of pressure monitoring and flow monitoring of water supply / gas supply pipeline networks that require terminal acquisition equipment to collect data. The terminal acquisition equipment in the prior art generally includes a data acquisition unit, a GPRS unit and a data processing unit. The data acquisition unit collects corresponding acquisition data at a monitoring point, and sends the acquisition data to the data processing unit. The processing unit receives the collected data and performs corresponding processing, and then sends it to the central management system in the SCADA syste...

Problems solved by technology

But along with the enlargement of city scale, high-rise buildings everywhere, the selection of monitoring point has certain difficulty, because the power consumption of data collection unit and GPRS unit is bigger, if data collection unit and described GPRS unit work all the time, make terminal collection equipment The overall power consumption is relatively large, and an AC power supply is required for power supply. If the monitoring point is far away from the AC power supply, the terminal acquisition device cannot find the corresponding AC power supply for power supply, and the data of the monitoring point cannot be collected.
