Guilong water supply valve application prospects The RTU and electric head equipment combination modes selected by the test scheme have the characteristics of high reliability and powerful functions, and the possibility of further improvement can be considered when using the scale.
Reduce system cost The remote communication/remote control device uses RTU based on short-wave communication during the test application. Although powerful, single-site equipment is expensive. You can try to select functional modules based on wireless digital public network with data acquisition and remote control functions, such as GPRS-RTU, CDMA-RTU, etc., to reduce the cost of single station construction.
2 Power supply is a bottleneck problem The pipe network valve is installed underground on the municipal road, and the appropriate power/lighting mains power supply may not be available. When the key valve needs remote control and can not solve the mains power supply, DC power supply, high output torque, low speed electric head can be used, and the power supply uses lead-acid battery.
The 48V14AH lead-acid battery pack commonly used in electric vehicles is selected, and the charging cycle is rotated for one month. It is calculated that more than 50 full-open-closed valve operations can be completed in the charging rotation cycle to meet the functional requirements. By strengthening the battery charging maintenance management, the valve can be remotely controlled without the mains power supply.
3 For the internal control of the large-capacity clear water pool, you can try to control the water supply according to the pipe network conditions to fully utilize the “peaking†function of the user's clear water pool.
