What is controllable remote wired intelligent water meter?

Answer:

Bus intelligent remote transmission water meterThe bus intelligent remote transmission system consists of bus system, direct reading water meter, collector, transmission line and so on. There are three types of bus direct reading water meter, such as CCD camera, direct reading type, photoelectric direct reading type and counting direct reading type. The CCD type of photographic camera direct reading remote meter wheel, data center back photo postprocessing for digital signal; optoelectronic device by photoelectric direct reading type direct reading word wheel reading, digital signal output; direct reading type, data acquisition, processing, storage and other work in one set, the digital signal output. The bus direct reading water meter needs no initialization, so it does not need power supply at all times. The installation is more convenient, and the maintenance cost is low during use.
Intelligent remote transmission water meter with branch line systemThe intelligent remote transmission water meter is the main mode adopted in the automatic meter reading system in our country. The utility model is composed of a remote water meter, a data collector and a concentrator, and a signal transmission circuit, etc. each water meter is connected to a data collector, and is connected with the concentrator by a data collector in parallel to the bus. Intelligent remote meter with mechanical meter for the measurement of the base table, sending device configuration, on the basis of the base table counting pointer rotation to the collector transfer count pulse or switch signal transmitting device with reed Holzer components, optoelectronic components, mechanical contact etc.. Whether the sending device is accurate and reliable, the count pulse of the real estate basically determines the accuracy of the remote meter reading system. The utility model has the advantages of low price, technology is relatively mature, monitoring better, but because each need to connect to the collector, and twenty-four hours of power supply, need initialization settings, midway disconnection power outages and other easily lead to data loss, the need of special maintenance, maintenance costs are high.
Wireless transmitting type intelligent remote transmitting water meter (controllable long-distance wired intelligent water meter)The wireless transmitting type intelligent remote transmitting water meter has functions of data acquisition, processing and storage, and is equipped with a wireless transmitting device to receive signals through a remote receiving device. This table does not need laying line and line maintenance, easy installation, simple construction, but the cost is higher.
Intelligent card type water meterSmart card water meter comes with collection, power, electric valve and valve control, smart card reader and other functions. The utility model has the advantages that the utility model is easy to install and needs no wire arranging, and the utility model can realize the water charging after the first charge. The main problems are: the tap water company is difficult to control, unable to determine the water table, also have a certain impact on the statistical sales slip, then if the valve can not accurately closed, smart card water meter will lose control of the meaning of water.
