Concentration ratio wireless control system and method

Abstract

The invention discloses a concentration ratio wireless control system, which is applied to the field of concentration ratio control. A wireless sensor unit is used for acquiring parameter data relative to the concentration radio. A wireless data acquisition unit collects data from the wireless sensor unit. A wireless control unit processes data transmitted from the wireless data acquisition unit, sends out feed-and-drain valve regulating commands according the processing results, and then transmits the regulating commands to the wireless control unit wirelessly. A wireless executing unit executes the feed-and-drain valve regulating commands to regulate water volume and keeps the concentration ratio at a proper value stably, so that safety in production is guaranteed while water resources are saved. Wireless transmission refers to data transmission based on the ZigBee wireless network, so that electromagnetic interference is avoided effectively, and error in data transmission process is decreased. In addition, the structure of the control system can be regulated at any time according to needs of the control system.

Description

technical field [0001] The invention relates to the field of circulating water concentration rate control, in particular to a wireless control system and method for concentration rate. Background technique [0002] As we all know, the concentration ratio is the core parameter of water balance, and also the key parameter that determines the water consumption of power generation. In order to ensure safe production, reduce production costs, and reduce water consumption, it is very necessary to reasonably and effectively control the concentration ratio of circulating water. Although the increase of the concentration ratio can save water, it does not mean that the higher the concentration ratio during operation, the better. Gradually increase the concentration ratio, that is, gradually increase the salt content in the water. When the salt content reaches a certain level, many problems such as corrosion and scaling will occur in the circulating water system. Therefore, it is parti...

Problems solved by technology

[0003] In the traditional concentration rate control system, almost all data transmission is wired data transmission, and the sensor data reception and control instruction transmission related to the concentration rate are completed through the data line; the system has the following deficiencies: 1) Poor reliability: in When the transmission line is damaged, the wired data transmission will be interrupted, which will easily lead to the loss of control of the enrichment rate control system; 2) Weak anti-interference ability: wired data transmission is susceptible to electromagnetic interference, which will lead to inaccurate detection data about the enrichment rate; 3) The structure of the concentration rate control system is inflexible: when the structure of the control system needs to be updated, the connection relationship of all related devices of the control system needs to be changed, and the workload is relatively large; 4) The cost is high: the wired connection device used for wired data transmission such as data Higher cost of lines etc.
