Abstract

The invention discloses a multipoint sampling and non-contact type smart card intelligent water meter, characterized by including a water meter body (1), a main controler IC2, a readwrite card circuit, a control circuit, a sampling circuit and a display (2), wherein the sampling circuit is composed of a magnet arranged on the corresponding code wheel required to sample in the water meter body (1) and a magneto-dependent sensor arranged on one side of the code wheel without the magnet; the output of the sampling circuit is connected with the corresponding input end of the main controler IC2; the readwrite card circuit is inductively connected with the non-contact type IC card; the output of the readwrite card circuit is connected with the input end of the main controler IC2, the signal output end of which is connected with the input end of the control circuit; the output end of the control circuit controls the onoff of the valve on the intake pipe of the water meter body (1). The invention has strong anti-aggressivity, good stability and high reliability.

Description

technical field [0001] The invention relates to a water meter, in particular to a stable and reliable multi-point sampling and non-contact IC card intelligent water meter. Background technique [0002] At present, with the continuous growth of human society population, the continuous acceleration of industrialization process and the rapid development of urban construction, urban water supply and water management systems are facing unprecedented pressure. Therefore, the rational and effective development and utilization of fresh water resources has become a worldwide important issue. In the case of serious shortage of water resources in many cities in China, many areas are facing the problem of collecting water fees. People are not conscious about the paid use of water resources. The investment in urban domestic sewage treatment is increasing, and disputes over water use are becoming more and more serious. serious. In order to alleviate the contradiction of water supply, co...
