Abstract
The invention discloses a method for giving an alarm on magnetic interference and protecting and shutting a valve for a wireless card type prepaid gas meter. The method comprises the following steps of (1) receiving an external interference signal via an antenna, (2) detection the interference signal received by the antenna by a detection module to acquire voltage, (3) detecting the detected voltage via a micro controller to acquire interference relative strength, (4), detecting frequency of the interference signal via a frequency detection module to acquire the frequency of the interference signal and transmitting the frequency to the micro controller, (5) employing various alarm schemes to given an alarm and protect and shut off the valve by the micro controller according to the interference signal strength and frequency, (6) repeating the step one to five, (7) transmitting the alarm information and valve protection and shutoff information to a combustion gas center via a wireless module by the micro controller when an alarm scheme is changed, and (8) recording the information by the combustion gas center after receiving the alarm information and valve protection and shutoff information sent by the combustion gas meter.
Description
Technical field
The present invention relates to a kind of method that wireless cassette pre-payment gas meter realizes magnetic interference warning and protection pass valve.
Background technology
Teletransmission is checked meter, the key problem that first will solve be how table is measured, the mechanical information that shows is converted to the electronic information that computing machine can process, i.e. data genaration.Namely traditional stem-winder installs magnet on certain gear, and correspondence position installs magnetic-sensitive elements, such as Hall element or tongue tube.Magnet is with pinion rotation, and when entering the induction zone of magnetic-sensitive elements, tongue tube adhesive exports pulse, then by counter circuit, pulse is converted into flow.It is simple that mechanical type table has structure, the advantage of easy realization, but principle of work itself determines mechanical type table has fatal weakness, i.e. the counting loss not even enumeration problem that brings of strong magnetic interference, secondary measurement, cumulative errors cause the problem of the low and error in reading of degree of accuracy.
Magnetic interference can hinder the work of long-range table tool, and the his-and-hers watches tool accuracy of measuring brings impact, detect the general mode adopting interference receiver or frequency spectrograph of interference, but cost is too high, cannot implement; Also have and adopt the mode of undesired signal amplification demodulator directly.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art; there is provided a kind of wireless cassette pre-payment gas meter to realize magnetic interference report to the police and protect the method for closing valve; the method adopts different alarm scheme according to the intensity of signal of begging for mercy and frequency; make warning more accurate; can valve-off in time; the interests of available protecting gas company, carry out record to valve opening and closing situation and put on record, effectively avoid dispute to produce.
The object of the invention is to be achieved through the following technical solutions: wireless cassette pre-payment gas meter realizes magnetic interference and to report to the police and the method for valve is closed in protection, and it comprises following sub-step:
S1: antenna receives external interference signals;
S2: detection module is carried out detection to the undesired signal that antenna receives and obtained voltage;
S3: microcontroller detects the voltage that detection obtains, obtains disturbing relative intensity;
