Abstract
The invention discloses a fuel theft alarm device for construction machinery, which comprises a microprocessor, a liquid level sensor, an alarm, a wireless transmission module and a wireless receiving module, wherein the microprocessor is respectively connected with the liquid level sensor, the alarm and the wireless transmission module. The alarm device has the advantages of simple circuit structure, high operational stability and low power consumption during operation. If the microprocessor judges that the later liquid level signal value is less than the previous liquid level signal value, it indicates that the fuel level in the fuel tank descends, and the microprocessor can start the alarm in time and instruct the wireless transmission module to transmit an alarm signal. On one hand, the alarm gives out alarm sound to frighten the thief stealing the fuel; and on the other hand, the wireless transmission module transmits the alarm signal, and the wireless receiving module receives the alarm signal and reminds the working personnel to stop the thief from stealing the fuel.
Description
Technical field
The present invention relates to the stolen warning device of a kind of fuel oil of on engineering machinery, installing and using.
Background technology
Engineering machinery is generally constructed under the circlet border in meagrely-populated or movement of population amount very much, and the time period that the engineering staff has a rest places engineering machinery in the open, and generally can not send the special messenger to keep an eye on this moment.Because meagrely-populated, the fuel tank of engineering machinery is bigger again, through regular meeting the stolen incident of fuel oil takes place.Some large-scale company, with the engineering machinery centralized management, but many engineering machinery occupations of land are wider, need to drop into the more personnel that keep an eye on, and increased the recruitment cost of enterprise.
Therefore; Existing engineering machinery is transformed; In case in time report to the police when having the stolen incident of fuel oil to take place and through infinite network alerting signal is sent to the user, one greatly reduces the stolen probability of engineering machinery fuel oil surely, reduces the user for taking precautions against the stolen human cost input of fuel oil.
Summary of the invention
The object of the present invention is to provide the stolen warning device of a kind of engineering machinery fuel oil, this warning device circuit structure is simple, safe and reliable.
The present invention to achieve these goals, the technical solution of employing is:
The stolen warning device of engineering machinery fuel oil comprises microprocessor, liquid level sensor, alarm, wireless sending module, wireless receiving module, and microprocessor is connected respectively with liquid level sensor, alarm, wireless sending module;
Microprocessor, uniformly-spaced the time is read the liquid level signal value of liquid level sensor monitoring, and adjacent twice liquid level signal Value Data compared, if the twice liquid level signal value in front and back is identical, is normal condition; If a back liquid level signal value, is explained oil level less than last liquid level signal value and descends that microprocessor starts alarm and instructs wireless sending module to send alerting signal;
Liquid level sensor is arranged in the fuel tank of engineering machinery;
Wireless sending module sends alerting signal when the instruction of receiving microprocessor;
Wireless receiving module is used to receive the alerting signal that wireless sending module sends.
Above-mentioned microprocessor is connected with the starting switch of engineering machinery; When starting switch placed " opening " gear, microprocessor " cut out "; When starting switch places " pass " gear, microprocessor " unlatching ".
Above-mentioned wireless sending module is set up through communication base station with wireless receiving module and is communicated by letter.
Above-mentioned wireless sending module and wireless receiving module use the GPRS signal communication.
Above-mentioned alarm comprises loudspeaker, and when alarm started, loudspeaker sent chimes of doom.
Beneficial effect of the present invention: the stolen warning device of this kind engineering machinery fuel oil, circuit structure is simple, and operation stability is strong, and power consumption is very little during work.A liquid level signal value explains that less than last liquid level signal value fuel level in tank descends after microprocessor judges, and microprocessor in time starts alarm and instructs wireless sending module to send alerting signal.On the one hand, the loudspeaker of alarm sends chimes of doom the thief of stealing oil is played certain fright effect; On the other hand, wireless sending module sends alerting signal, after wireless receiving module is received alerting signal, reminds the staff to arrive in the very nick of time and prevents thief to steal oil.In addition, the sending module of the stolen warning device of this kind engineering machinery fuel oil can also with the police system UNICOM of public security bureau, in time please police's assistance arrest thief.
