Description
(1), technical field
The utility model relates to a kind of explosion-proof leak alarm of digital remote control motor tire that can monitor the air pressure of automobile tire height.
(2), background technology
At present, the volume of production and marketing of China's automobile increases day by day, especially high capacity waggon.But owing to there is not the control monitor unit of air pressure of automobile tire height, cause automobile rolling over tire owing to leaking gas on the way, owing to temperature rises, air pressure becomes big and blows out, and brings inconvenience to replacing and maintenance.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of digital remote control motor tire explosion-proof leak alarm, and it can monitor the variation of air pressure of automobile tire at any time, maintenance at any time, and also simple in structure, cost is low.Filled up a domestic blank.
The technical scheme in the invention for solving the technical problem is: it comprises the projector and the receptor of digital signal, described projector is fixed on the automobile rim, the pressure sensor AK of projector is fixed on the valve of motor tire, the positive pole of its output contact one termination transmitter power, the other end connects the A point of transmitter circuit, A point one end meets 9 of coder IC1 by resistance R 3,14 pin and negative pole, 10 pin of another termination coder IC1 also connect 18 pin of coder IC1 by diode VD2,2 pin of element IC2 are penetrated in output pin 17 sending and receiving of coder IC1,1 of emission part IC2,3 pin are just connecing respectively, negative pole, 4 pin of radiated element IC2 connect antenna.
Described receptor is fixed in the operator's compartment, the A of the Rcv decoder IC3 of receptor, B, C, the D pin is by diode VD6, VD7, VD8, VD9 meets 10 of speech IC IC4 respectively, 11,13,14 pin, 4 pin of speech IC IC4 connect negative pole, 7 pin are output pin, connect 3 pin of power amplifier IC5 by capacitor C 4,2 of power amplifier IC5,4 pin connect negative pole, 8 of described speech IC IC4,6 pin of 12 pin and power amplifier IC5 connect positive pole by three-terminal voltage-stabilizing, 5 pin of power amplifier IC5 are output pin, connect loudspeaker Y by capacitor C 2.
Because on the motor tire pressure sensor is housed, when pressure was below or above setting value, loudspeaker were promptly emitted this wheel pressure deficiency or overtemperature alarm, can keep in repair at any time.Simple in structure, easily processing and manufacturing, cost is low.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model transmitter circuit schematic diagram;
Fig. 2 is the utility model acceptor circuit schematic diagram.
(5), the specific embodiment
It comprises the projector and the receptor of digital signal, and described projector is fixed on the automobile rim, and the pressure sensor of projector is fixed on the valve of motor tire, and several wheels are arranged, and cooresponding just have several pressure sensors.Be example with two wheels on the automobile in this example, so two pressure sensors are arranged, each sensor has two contacts, left side AK, BK, the right CK, DK.The positive pole of the output contact one termination transmitter power of each pressure sensor, the other end connect A, B, C, the D point of transmitter circuit respectively.A, B, C, D point one end connect 9,14 pin and the negative poles of coder IC1 respectively by resistance R 3, R4, R5, R6, the other end connects 10,11,12,13 pin of coder IC1 respectively and connects 18 pin of coder IC1 respectively by diode VD2, VD3, VD4, VD5.2 pin of element IC2 are penetrated in output pin 17 sending and receiving of coder IC1, and 1,3 pin of emission part IC2 connect positive and negative electrode respectively, and 4 pin of radiated element IC2 connect antenna.
Described receptor is fixed in the operator's compartment, A, the B of the Rcv decoder IC3 of receptor, C, D pin connect 10,11,13,14 pin of speech IC IC4 respectively by diode VD6, VD7, VD8, VD9,4 pin of speech IC IC4 connect negative pole, 7 pin are output pin, connect 3 pin of power amplifier IC5 by capacitor C 4.2,4 pin of power amplifier IC5 connect negative pole, and 8,12 pin of described speech IC IC4 and 6 pin of power amplifier IC5 connect positive pole by three-terminal voltage-stabilizing.5 pin of power amplifier IC5 are output pin, connect loudspeaker Y by capacitor C 2.For whether indicating circuit works, at indirect series connected resistance R 11 of positive and negative electrode and light-emitting diode VD12.For the demonstration time, at the indirect electronic watch IC6 of positive and negative electrode.
If left side mounting of tyre pressure sensor AK, when air pressure is lower than setting value, the pressure sensor AK contact closure on it, coder IC1 output corresponding codes is sent by radiated element IC2.Decode after Rcv decoder IC3 receives and judge, from the A pin output of Rcv decoder IC3, speech IC IC4 exports cooresponding warning speech signal, as " left side low tyre is asked on-call maintenance " etc.The warning speech signal is emitted by loudspeaker Y after power amplifier IC5 amplifies, and reports to the police to chaufeur.
