Abstract
This utility model is related to a kind of anti-lost warning system of car plate, and its technical characterstic is：It is made up of permanent magnet and alarm, permanent magnet is on car plate rear board, alarm is corresponding with permanent magnet and is arranged on vehicle body, the alarm is made up of the detection warning circuit of casing and its inside, controlling switch and speaker is provided with casing, detection warning circuit is by microprocessor, magnetic switch, resistance, DC source, the control end of microprocessor connects the positive pole of DC source by resistance and controlling switch, the input connection magnetic switch of microprocessor, testing result is simultaneously passed to microprocessor by magnetic switch state for detecting permanent magnet corresponding with permanent magnet ZT, microprocessor is connected with speaker.This utility model is reasonable in design, and when car plate comes off from vehicle body, alarm sends alarm after sensing, reminds car owner to note car plate situation, it is ensured that the normal operation of electric power rescue and relief work.
Description
Technical field
This utility model belongs to electricity emergency car technical field, especially a kind of anti-lost warning system of car plate.
Background technology
During Utilities Electric Co.'s rescue and relief work, electricity emergency car plays an important role.But, electric power is speedily carried out rescue work

Phenomenon, therefore can to electric power rescue and relief work be smoothed out bring certain puzzlement.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of anti-lost warning system of car plate, solves
Electricity emergency car car plate drops the problem that brings.
This utility model solves its technical problem and takes technical scheme below to realize：
A kind of anti-lost warning system of car plate, is made up of permanent magnet and alarm, and the permanent magnet is after car plate
On panel, the alarm is corresponding with permanent magnet and is arranged on vehicle body, detection of the alarm by casing and its inside
Warning circuit is constituted, and is provided with controlling switch and speaker in casing, and the detection warning circuit is opened by microprocessor, magnetic control
Pass, resistance, DC source, the DC source are powered for alarm, and the control end of the microprocessor is by resistance and control
The positive pole of switch connection DC source, the input connection magnetic switch of microprocessor, the magnetic switch and permanent magnet ZT phases
To being applied to detect the state of permanent magnet and testing result being passed to microprocessor, the microprocessor is connected with speaker
Connect, when permanent magnet comes off, controlling loudspeaker sends alarm sound.
Advantage of the present utility model and good effect are：
This utility model is installed a permanent magnet on car plate rear board and installs a report with permanent magnet adjacent position
Alert device, when car plate comes off from vehicle body, with car plate away from alarm, alarm sends alarm to permanent magnet after sensing, reminds
Car owner notes car plate situation, drops loss so as to be effectively prevented from electricity emergency car car plate, it is ensured that electric power rescue and relief work work
The normal operation that makees.
Description of the drawings
Fig. 1 is system connection diagram of the present utility model；
The circuit diagram of alarm of the present utility model during Fig. 2.
Specific embodiment
This utility model embodiment is further described below in conjunction with accompanying drawing：
A kind of anti-lost warning system of car plate, as shown in figure 1, be made up of permanent magnet and alarm two parts, described permanent
, on car plate rear board, the alarm is corresponding with permanent magnet and is arranged on vehicle body, and the alarm is by machine for Magnet
The detection warning circuit of shell and its inside is constituted, be provided with casing controlling switch K1 and speaker B and with detection warning circuit
It is connected, when car plate comes off, with car plate away from alarm, alarm sends alarm after sensing to Magnet.
As shown in Fig. 2 the detection warning circuit of casing internal is by microprocessor IC, magnetic switch K2, resistance R, unidirectional current
Source GB, the DC source GB power for alarm.The microprocessor IC control ends are connected by resistance R and controlling switch K1
The positive pole of DC source GB, the input connection magnetic switch K2 of microprocessor IC, magnetic switch K2 and permanent magnet ZT phases
To being applied to detect the state of permanent magnet ZT and testing result being passed to microprocessor IC, the microprocessor IC and speaker
B is connected, and when permanent magnet ZT comes off, controlling loudspeaker B sends alarm sound.
Operation principle of the present utility model is：Controlling switch K1 is opened, when car plate and permanent magnet are located at vehicle body, magnetic control
Switch K2 disconnects, and alarm is in off working state；When car plate and permanent magnet come off, permanent magnet ZT is away from magnetic switch
K2, magnetic switch K2 are in closure state, and the control end of microprocessor IC connects cathode power supply by resistance R, rapid conducting, raise one's voice
Device B obtain electric send chimes of doom, remind car owner to note car plate situation.
It is emphasized that embodiment described in the utility model is illustrative rather than determinate, therefore this reality
With the new embodiment including being not limited to described in specific embodiment, every new according to this practicality by those skilled in the art
The other embodiment that the technical scheme of type draws, also belongs to the scope of this utility model protection.
