Header of low-power-consumption network intelligent water meter and application method thereof

Abstract

The invention relates to a header of a network intelligent water meter, which comprises a header casing provided with a water inlet and a water outlet, a flow sensor and a flow control system, wherein the flow control system comprises a microprocessor, a power supply connected with the microprocessor and provided with a low-electric-quantity alarm circuit, a control module of the power supply, a flow data acquisition module, an interval type display unit module, a triggering type communication and data transmission module and a reset setting module, low-power-consumption triggering type communication and transmission, and remote power supply and interval type display modes are adopted in the invention to effectively reduce the power consumption of the header; the power consumption of the header is 10% to 25% that of a background technology; and the reliability and the stability of the header can be guaranteed by utilizing the functions of low-electric-quantity alarm and antimagnetic disturbance. Thus the header of a network intelligent water meter has the advantages of high precision of water consumption measurement and display, and remote meter reading, low energy consumption of the header, simple structure and convenient maintenance of the header, and the like. The header of a network intelligent water meter can meet the requirements on all-weather communication and remote meter reading and is beneficial to enhancing the characteristics of popularization and application of the network intelligent water meter.

Description

technical field [0001] The invention belongs to a meter head of a flow digital water meter with a remote meter reading function and a method for using the meter head, in particular to a micro-embedded digital control circuit that can not only measure the flow rate but also perform remote meter reading. A low-power consumption intelligent (digital) water meter head and a method of use thereof. The meter is especially suitable for matching with the water network water supply system that does not need to replace the battery for a long time. It is used to record the user's water consumption and transmit the recorded data to the management (charging) department for processing through the network. Background technique [0002] In recent years, with the development of electronic technology, communication technology and sensing technology, people have developed a series of new network smart water meters. These measuring instruments obtain water flow information through various types...

Problems solved by technology

This kind of technology is recorded in the patent document with the announcement number CN201035737Y and the invention name "Digital Remote Transmission Meter Reading System for Flow Meters"; the patented technology includes: image acquisition and preprocessing part, digital signal processing part, data storage Module and display part, due to the use of image acquisition technology, DSP as processor, and LED long-term display, the technology consumes a lot of power, requires frequent battery replacement, and is not easy to work stably for a long time; and in The patent document whose publication number is CN101526370A and whose invention name is "Remote Control Intelligent Water Meter" discloses a kind of including: a base meter with an electromechanical valve, a CPU connected to the base meter, a water source inlet and outlet, a counting reed switch, and a water meter connected to the CPU. Remote controller for data transmission; this technology uses a reed switch as a sensor, and combines the RS485 bus with the CPU to query, process, and remotely control the water volume data and water consumption information of the water meter. The counting accuracy and anti-interference ability are poor, and the circuit is complicated. , The power consumption of the communication module is high; it is powered by batteries, and it does not provide a low-battery alarm function. First, if the battery of the water meter terminal is exhausted, the new water consumption will not be recorded. Second, the maintenance workload and difficulty in troubleshooting; In addition , due to the complex working environment of the meter head, and the system is not equipped with protection and interference removal devices, electromagnetic and other interferences are frequent in humid and thunderstorm weather conditions, and errors in meter lookup or water cutoffs often occur during use

Therefore, the above-mentioned technology has complex circuits and structures, high power consumption, short stable operation period, no low battery alarm, and protection functions against electromagnetic and lightning interference, as well as the resulting water consumption not being recorded or mistakenly cut off. Defects such as table errors
