Described tongue tube sensor is two, is respectively the first tongue tube sensor and the second tongue tube sensor, and the first tongue tube sensor is connected with single-chip microcomputer respectively with the second tongue tube sensor.

Described the first tongue tube sensor with the second tongue tube sensor setting in the different position of base table.

With respect to prior art, the utlity model has following beneficial effect:

The utility model arranges tongue tube sensor for detection of water flow signal, water flow signal is sent to single-chip microcomputer, single-chip microcomputer sends to concentrator by gsm communication module by water consumption, after being gathered by concentrator, send to host computer, realize the remote intelligent meter recording of water meter, avoided the inconvenience of manually visiting and checking meter.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation block diagram.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Referring to Fig. 1: long-distance meter-reading system, comprises base table, tongue tube sensor, single-chip microcomputer, driver module, solenoid valve, gsm communication module, concentrator and host computer.Base table is arranged on the inlet pipeline of running water pipe, and tongue tube sensor setting is on base table, for gathering water flow signal.Tongue tube installation of sensors is near the counting scale of base table, permanent magnet is installed on counting scale, when counting scale turns around, permanent magnet produces a metrical pulse signal through tongue tube sensor, and tongue tube sensor sends to single-chip microcomputer to measure this metrical pulse signal.Single-chip microcomputer adopts AT89C51 single-chip microcomputer, single-chip microcomputer is connected with tongue tube sensor, driver module and gsm communication module respectively, single-chip microcomputer is processed metrical pulse signal, and the water yield signal after processing is sent to concentrator by gsm communication module, concentrator sends the data to host computer by cable network or wireless network, realizes remote meter reading.In order to improve the precision of metering, tongue tube sensor setting is two, be respectively the first tongue tube sensor and the second tongue tube sensor, the first tongue tube sensor is connected with single-chip microcomputer respectively with the second tongue tube sensor, the first tongue tube sensor with the second tongue tube sensor setting in the different position of base table.When metering, when the first tongue tube sensor adhesive, single-chip microcomputer is recorded metrical pulse signal, detect again the second tongue tube sensor, the metrical pulse signal that the second tongue tube sensor only detected is only effective signal, if the first tongue tube sensor only detected or the pulse signal of the second tongue tube sensor only detected, or the pulse signal that the first tongue tube sensor and the second tongue tube sensor simultaneously detected is invalid signals.This can effectively be avoided metering disk to stop operating and permanent magnet is parked near tongue tube and the inaccurate problem of metering causing, also can avoid artificial complementary field to disturb water meter and the inaccurate problem of counting that causes.Driver module is DC relay, and driver module is connected with solenoid valve, when needs shut electromagnetic valve, by Single-chip Controlling driver module, drives closed electromagnetic valve.As single-chip microcomputer detects the pulse signal of the first tongue tube sensor and the second tongue tube sensor simultaneously, can be judged to be artificial additional magnet and disturb water meter counting, can drive driver module shut electromagnetic valve.
