It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1, in the present invention, the door control device is already installed with a mechanical switch button, wherein the door control device is located at the far end, and the mechanical switch button is located at the near end, i.e. there is a certain distance between the door control device and the mechanical switch button.
When in transformation, a local control module, a secondary bus module, a non-contact induction sensor antenna and a primary bus module are added on the basis of the existing equipment.

The DC-DC circuit outputs 12/24V on one side to the master two-bus circuit, which supplies 12/24V to the proximally located slave two-bus module via a bus consisting of 2 conductors multiplexed for power and signal transmission. And on the other hand, the DC-DC circuit converts the 12/24V voltage into proper voltage to be supplied to the main relay and the main MCU, so that the main relay and the main MCU can work normally. The main relay gives switching signals REX1 and REX2 to the door control device, the main relay is controlled by the main MCU to be switched on or off according to received switching state data, and therefore corresponding switching signals REX1 and REX2 are given to the door control device, and the door control device opens the door. The master MCU detects LED control signals LEDIN1 and LEDIN2 and a failure signal DISABLE given by the door control equipment through the input detection circuit, the master MCU generates corresponding control data according to the received LED control signals LEDIN1 and LEDIN2 and the failure signal DISABLE, the control data are sent to the master two-bus circuit, and the master two-bus circuit sends the received control data to the slave two-bus module through the bus.
In this embodiment, since the door control device is spaced from the mechanical switch button by a certain distance, the wires connecting the buses of the secondary bus module and the primary bus module are long, and in order to facilitate wiring, in this embodiment, the buses are composed of 2 power supplies and wires for multiplexing communication signal transmission.
In this embodiment, the slave two-bus module includes a DC-DC circuit two, a slave two-bus circuit, a signal input detection circuit, and a slave MCU. And after receiving the 12/24V voltage, the DC-DC circuit II converts the voltage into a proper voltage and supplies the proper voltage to the slave MCU, so that the slave MCU can work normally and simultaneously supplies power to the local control module.
The slave two-bus circuit also receives control data sent from the master two-bus circuit and forwards the control data to the local control module. The slave two-bus circuit also forwards the switch state data generated by the slave MCU to the master two-bus circuit through the bus.
The slave MCU detects the switch state signal output by the local control module through the signal input detection circuit, then generates switch state data according to the switch state signal, and sends the switch state data to the slave two bus circuits. After receiving the control data from the two bus circuits from the MCU, the control data is forwarded to the local control module.
In this embodiment, the local control module includes a local relay, a local MCU, an LED lamp, a buzzer, and a dial switch. The 5V voltage is supplied to the local control module from the two-bus circuit, so that the local control module can work normally. The existing mechanical switch button and the newly added non-contact induction sensor indirectly and directly give a switch signal through the local control module, wherein the non-contact induction sensor gives the switch signal to the local MCU, and the local MCU controls the local relay to be switched on or off according to the received switch signal, so that a switch state signal is generated; the switch signal given by the mechanical switch button is connected in parallel with the output end of the local relay to directly generate a switch state signal. The slave MCU detects the switch state signal through the input detection circuit. The local MCU also receives the control data from the slave MCU, and the local MCU lights the corresponding LED lamps according to the LED control signals LEDIN1 and LEDIN2 in the control data and controls the buzzer to give out related sound prompt information according to the corresponding lighting states. The local MCU can also light the corresponding LED lamp according to the detected switch signal. And the local MCU no longer responds to the switching signal given by the non-contact induction sensor according to the failure signal DISABLE in the control data.
The utility model discloses a working process brief follows:
1) after a local MCU on the local control module detects a switching signal through an induction antenna, a buzzer sounds, an LED flashes and a local relay acts;
and after the slave MCU on the slave two bus modules detects the action of the local relay on the local control module, the switch state data is sent to the master two bus module through the two bus circuits.
And after the main two-bus module receives the switching state data, the main relay is controlled to act, and the door control equipment is controlled to open the door.
2) And a switch signal output by a mechanical switch button on the local control module is connected to the output end of the local relay in parallel. After the mechanical switch button is pressed, the door control equipment can be controlled to open the door according to the same data transmission principle as the above 1).
3) And after detecting the level changes of the LEDIN1 and LEDIN2 of the LED control ports of the door control equipment, the master MCU on the master two-bus module sends control data to the slave two-bus module through the two-bus circuit.
After receiving the data from the two bus modules, the corresponding data interfaces LEDIN1 and LEDIN2 are controlled to output the same level to control the LED lamp display on the local control module.
