Internet-of-things signal transmission based frequency-variable constant-pressure water supply system and frequency-variable constant-pressure water supply method

Abstract

The invention discloses an internet-of-things signal transmission based frequency-variable constant-pressure water supply system which comprises an internet-of-things signal collection and transmission device, a water inlet, a water pump unit, a water outlet and a frequency-variable control cabinet. The water inlet is arranged at a water source and is connected with the input end of the water pump unit through a pipeline. The output end of the water pump unit is connected with the water outlet through a pipeline. The water outlet is connected with a water consuming system through a pipeline. The internet-of-things signal collection and transmission device arranged at the extreme pressure point of the water consuming system collects pressure signals of the extreme pressure point and sends the signals to the frequency-variable control cabinet. The frequency-variable control cabinet controls the water pump unit to operate in a frequency-variable mode according to the signals. According to the system, real-time transmission of the signals is realized through the internet of things, real-time monitoring on a signal detector and a frequency converter is realized, and accordingly, stability and safety of the water supply system are guaranteed. The invention further discloses an internet-of-things signal transmission based frequency-variable constant-pressure water supply method.

Description

technical field [0001] The invention relates to a water supply method, in particular to an Internet of Things signal transmission frequency conversion constant pressure water supply system. The invention also relates to a frequency conversion and constant pressure water supply method for transmitting signals through the Internet of Things. Background technique [0002] At present, residents' domestic water and enterprise production water basically use frequency conversion water supply. Since the most unfavorable point in the water system is the highest and farthest point, usually the demand pressure of a most unfavorable point is estimated to set the pressure of the water supply system, and the frequency conversion water supply is performed according to the estimated demand pressure value. [0003] Existing water supply equipment collects the pressure signal at the outlet of the water pump through the detection device, and transmits the pressure signal to the frequency conv...

Problems solved by technology

The biggest advantage of this frequency conversion water supply is the stable water supply pressure; the disadvantage is that in order to ensure the most unfavorable point of water use, the pressure can only be estimated to be higher, leaving more margin in case the most unfavorable point does not use water

[0004] Due to the inability to accurately grasp the real pressure demand of the most unfavorable point, the error is too large and the operation of the water supply system wastes energy; due to the high pressure of the water supply system, the flow rate of the pipeline is too fast, which will cause a waste of water resources

[0005] In addition, once the signal detection device or the frequency converter fails, the entire water system will stop water supply, and the long supply cycle of the frequency converter often leads to friction disputes between residents and property companies and water supply companies caused by the lack of water for many days. For this reason, the water supply cut off led to the production shutdown of enterprises.
