Abstract

The invention discloses an NB-IoT wireless valve controlled water meter, which comprises a field controller, a data input module, a communication interface, a field valve, a field instrument, and a user terminal, wherein the data input module, the communication interface, the field valve and the field instrument are connected to the field controller; the communication interface is connected to a local area network based on an NB-IoT network and formed by an IoT communication module; the user terminal is connected to the local area network; and region partition is carried out for a user first,an IoT communication module is matched for each region, the IoT communication modules among the regions are constructed to form a local area network, the field controller is connected with at least one IoT communication module in the local area network to obtain data of all field devices in the local area network, and the problem of the last kilometer of data transmission is effectively solved byusing the local area network. Meanwhile, a data input module is installed for the field controller, and a field operator can control the field device more quickly through the data module.

Description

technical field [0001] The invention relates to an automatic instrument, in particular to an NB-IoT wireless valve-controlled water meter. Background technique [0002] Automated instruments are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc. are all instruments. In a broad sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission and data processing, such as pneumatic regulating instruments and electric regulating instruments used in the automatic control of industrial production processes, as well as distributed instrument control systems. instrumentation. Instrumentation improves, extends, or supplements human faculties. People use sensory organs to see, hear, taste, and touch external things, and instruments such as micros...
