the output end of the transformer circuit 3 is respectively connected with the power input ends of the PTC drive circuit 4, the main control circuit 5 and the PTC signal acquisition circuit 6.
The operation principle of the PTC controller with sleep function provided in this embodiment is further described as follows:
after the 12V power supply is started, the LIN transceiver U1 enters a standby mode, at the moment, an inhibit signal output pin INH of the LIN transceiver U1 sends a high-level signal to a B pole of a triode Q2 through a resistor R5 to conduct the triode Q2, the G pole voltage of the MOS tube Q1 is pulled down after the triode Q2 is conducted, so that the MOS tube Q1 is conducted, at the moment, the 12V power supply flows to a transformer circuit 3 through the MOS tube Q1, the transformer circuit 3 supplies power to a PTC drive circuit 4, a main control circuit 5 and a PTC signal acquisition circuit 6 after switching the power supply, namely, the 12V power supply respectively supplies power to the PTC drive circuit 4, the main control circuit 5 and the PTC signal acquisition circuit 6 after passing through the MOS tube Q1 and the transformer circuit 3, at the moment, the PTC drive circuit 4, the main control circuit 5 and the PTC signal acquisition circuit 6 enter a working state, and at the moment, the PTC controller enters the working state.
After the main control circuit 5 enters a working state, a signal is sent to the LIN transceiver U1 through the signal sending pin P2, and the LIN transceiver U1 enters a normal working mode after receiving the signal sent by the main control circuit 5.
After the LIN transceiver U1 enters the normal operating mode, at this time, the LIN transceiver U1 communicates with the main control circuit 5 through the signal receiving pin RXD and the signal transmitting pin TXD, and receives a control signal input by a user through the vehicle-mounted system through the LIN bus 1.
When the LIN transceiver U1 does not receive a control signal input by a user within a preset time period, it sends a sleep signal to the main control circuit 5, at this time, the main control circuit 5 sleeps that the control pin P1 outputs a low level signal, the low level signal passes through the resistor R4 to the pin 1 of the photoelectric coupler U2, so that the pins 3 and 4 of the photoelectric coupler U2 are not conducted, so that the pin 3 of the photoelectric coupler U2 is at a low level, so that the enable pin EN of the LIN transceiver U1 is at a low level, when the enable pin EN of the LIN transceiver U1 is at a low level, the inhibit signal output pin INH continuously outputs a low level, so that the triode Q2 is not conducted, so that the G of the MOS transistor Q1 is at a high level, so that the MOS transistor Q1 is not conducted, so that the input end of the transformer circuit 3 has no power input, so that the PTC drive circuit 4, the main control circuit 5, and the PTC signal acquisition circuit 6 also have no power input, at this time, the LIN transceiver U1 enters a sleep state, and the PTC controller enters a sleep mode.
When a user inputs an air-conditioning heating signal through a vehicle-mounted system, the LIN bus 1 sends the air-conditioning heating signal to the LIN transceiver U1, the inhibiting signal output pin INH of the LIN transceiver U1 outputs a high-level signal at the moment, the triode Q2 is conducted at the moment, the 12V power supply outputs power to the transformer circuit 3 through the D pole of the MOS tube Q1, the transformer circuit 3 outputs power to the PTC drive circuit 4, the main control circuit 5 and the PTC signal acquisition circuit 6 respectively, and therefore the PTC controller with the dormancy function enters a normal working state.
When a user turns off the air conditioner heating signal input by the vehicle-mounted system, the LIN bus 1 sends the air conditioner heating signal to the LIN transceiver U1, at the moment, the LIN transceiver U1 sends the air conditioner heating signal to the main control circuit 5, at the moment, the main control circuit 5 outputs a low-level signal by the sleep control pin P1, and at the moment, the PC controller enters a sleep mode.
Above, the PTC controller with sleep mode function that this embodiment provided can reduce the energy consumption, and specifically, in the car, can avoid the condition that the vehicle-mounted air conditioner high power consumption standby that the condition caused when touching the vehicle-mounted air conditioner power by mistake, or when not setting up the heating temperature after opening the vehicle-mounted air conditioner, or when closing the air conditioner not and closing the air conditioner power in the time, etc. to reach the mesh that reduces the energy consumption.
