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...
