In the sensor control part (30), the signal of the induction table reset circuit (27) operates the legacy induction table (31), the legacy induction table (31) senses 1 to 2 times of action and does not operate for more than 3 times, and then keeps a standby state, when the legacy induction table (31) continuously operates for more than 3 times, the action continuous (32) circuit is driven, and the action continuous (32) circuit continuously outputs an operation instruction to the alarm sending part (40) until the 2 nd preset time which is input in advance on the action time timer (33) is preset.
In order to solve the problems of the discharge solution of a common power supply and the long-time non-operation of a driver, the action time timer (33) confirms the state of a left child in a car every 4-6 hours at least, and stops sensing and operating after a set time.
The alarm transmitting unit (40) is a system for amplifying the voice guidance of the one-chip microcomputer chip (42) by the OCL amplifier (41) and notifying the outside by the audio mixer (43) with respect to the signal transmitted by the operation continuation circuit (32).
In order to ensure that the circuit is started in the internal and external radiant heat environments for a long time, the OCL amplifier (41) uses a standard thermal baffle by an electric screwdriver and is suitable for an outdoor sound mixing box, and a single chip microcomputer chip (42) is provided with a circuit so as to continuously and repeatedly process information.
to be suitable for human heat perception sensor, can set up about 1 in the interior access & exit upper portion of car, but set up in the interior canopy top of car or like prior art, when the bottom surface sets up a plurality ofly, the unusual phenomenon of operation will take place certainly, and this can lead to commercial value to be restricted.
The system designed by the invention can be used for the driver to regularly detect with the simplest and simplest operation, and for convenience, the driver can listen to an option switch for playing the audio effect and a delay or test (timer) option switch without manually operating the system by using a loudspeaker in the vehicle except for the test of the audio effect without going outside the vehicle.
Industrial applications
