At the same time, the power line and train line must also be extended to the electronic door controllers of other doors through this terminal block. As a result, the electronic control system has a large structure, complex wiring, cumbersome wiring harness manufacturing process, difficult assembly, and a high overall cost.

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1-4As shown, a rail vehicle electronic door controller with integrated signal conversion and expansion includes: an external wiring plug 1, a door controller end cap 2, an internal system interface board 3, a door controller mainboard 4, and a door controller housing 5. The external wiring plug 1 includes a two-wire female connector plug 11, a power supply air switch interface and input port plug 12, an output port plug 13, and a motor interface plug 14. The internal system interface board 3 includes a power supply air switch interface and input port socket 31, an output port socket 32, a motor interface socket 33, a two-wire female connector socket 34, a printed circuit board 35, and a board-to-board connector plug 36. The door controller mainboard 4 includes a board-to-board connector socket and a control circuit board 44. The board-to-board connector sockets include a board-to-board input and output port socket 41, a board-to-board power supply socket 42, and a board-to-board motor three-phase line socket 43.

[0023] A control circuit board is provided in the door controller housing, and the front end of the control circuit board is respectively connected to a board-to-board input and output port socket 41, a board-to-board power supply socket 42, and a board-to-board motor three-phase line socket 43; the printed circuit board is vertically arranged at the opening of the door controller housing, and a board-to-board connector plug is provided on the back of the printed circuit board, and the board-to-board connector plug is respectively connected to the board-to-board input and output port socket 41, the board-to-board power supply socket 42, and the board-to-board motor three-phase line socket 43, and the front of the printed circuit board is provided with a power supply air switch interface and an input port socket 31, an output port socket 32, a motor interface socket 33, and a 2-wire hole Type connector socket 34; the door controller end cover 2 is fixed at the opening of the door controller housing 5; the power air switch interface and input port socket 31, the output port socket 32, the motor interface socket 33, and the 2-wire hole type connector socket 34 pass through the door controller end cover 2; the end of the 2-wire hole type connector plug 11 is connected to the 2-wire hole type connector socket 34, the end of the power air switch interface and input port plug 12 is connected to the power air switch interface and input port socket 31, the end of the output port plug 13 is connected to the output port socket 32, and the end of the motor interface plug 14 is connected to the motor interface socket 33.

[0024] The two-wire female connector plug 11 is used to connect the vehicle's power supply and input and output signals. This two-wire female connector allows for serial connection of power and signals without increasing the number of sockets. The power air switch interface and input port plug 12 provides an interface for the vehicle's input power after it passes through the air switch. It also provides an input interface for door control signals such as fully closed, fully locked, and emergency unlocking, and provides a power interface for various vehicle switches. The output port plug 13 provides an output interface for vehicle output control signals such as buzzers, solenoid valves, and indicator lights. The motor interface plug 14 provides a motor interface for the door motor, including the motor's three-phase wires, encoder power, and signals.

[0025] The board-to-board input and output socket 41 is used to provide an interface for the input and output of electronic door controller signals. Electronic door controller signals include train signal line input, various door switch signal inputs, door controller signal outputs, and motor encoder signals. The door controller signal lines are concentrated in one socket, which facilitates the layout and wiring of the door controller motherboard. The board-to-board power socket 42 is used to provide an interface for the input power of the entire door controller. It uses a high-current socket to ensure reliable power supply for the entire door controller. The board-to-board motor three-phase line socket 43 provides an interface for the three-phase line input of the vehicle door motor and also uses a high-current socket to ensure reliable motor drive.

[0026] Example 1:

[0027] Each jack of the 2-wire female connector plug is connected to two wiring holes, which can realize the parallel connection of the electronic door controller on the train line. The train lines such as power line, zero speed, door enable, etc. come from the same signal source on the train and need to be connected to all electronic door controllers on the same side at the same time. On the door controller of the present invention, the power line and train line are connected to one hole position of the 2-wire female connector plug, and then directly connected to the next door controller with a cable from the other connected hole position. The cables of independent single door mechanisms, such as power air switch, door closed in place, locked in place, emergency unlocking and other input port signals are connected to the input port plug, and this connector also provides power for various switches. Output signals such as buzzer and indicator light are connected to the output plug. The motor line is connected to the motor interface plug.

[0028] The printed circuit board is placed perpendicular to the electronic door controller to minimize its size. Signal connections between various sockets are achieved through on-board wiring. The two-wire female connector socket is used for train wiring and connects to an external two-wire female connector plug. Other connector sockets include a power air switch interface, input and output sockets, and motor interfaces, which connect to external connectors. The board-to-board connector plugs include one input and output plug, one motor three-phase plug, and one power plug. The input and output plugs utilize connectors with a large number of interfaces and low current draw. This facilitates the integration of various train input signals, switch input signals, door controller output signals, and motor encoder signals into a single connector, facilitating printed circuit board layout and wiring, reducing connector size and door controller size. The motor three-phase plug and power plug utilize high-current connectors to ensure reliable power supply and motor drive for the entire door controller.

[0029] The door controller mainboard contains three board-to-board connector sockets: one for input and output ports, one for the motor's three-phase cables, and one for power. These sockets connect to the three board-to-board connector plugs on the system interface board, enabling signal exchange between the system interface board and the mainboard.

[0030] Example 2:

[0031] With the exception of communication cables, all other train cables and door mechanism cables in the door system are connected to external wiring plugs. Once the door controller is installed, signal transfer via external terminal blocks is eliminated. Instead, the external wiring plugs are plugged directly into the connector sockets on the system interface board. All signals are converted to board-to-board connectors on the system interface board and main board, respectively. The system interface board and main board are connected via board-to-board connectors to achieve signal exchange.

[0032] The mainboard's external interfaces are differentiated according to power and signal types, and signal sockets, power sockets, and motor sockets are used to connect to the system interface board for board-to-board connection. This connection method not only ensures reliable connection, but also reduces the size of the electronic door controller and improves assembly efficiency.

[0033] Example 3:

[0034] When the electronic door controller of the present invention is used, the installation steps are as follows:

[0035] The internal system interface board and door controller mainboard are installed in the door controller end cap and door controller housing, respectively. Position the internal system interface board and door controller end cap assembly perpendicular to the mainboard. Connect the input and output plugs of the board-to-board connector to the input and output sockets, the motor three-phase cable plug to the motor three-phase cable socket, and the power plug to the power socket. The door controller now displays the two-wire female connector socket, the input and output sockets, and the motor socket.

[0036] Train lines such as the power supply, zero speed, and door enable are connected to one hole of a two-wire female connector plug according to the interface definition. The lines are then connected from the other connected hole of the plug to the two-wire female connector plug of the next door controller, and this cycle continues until the last door controller. The power air switch is connected to the input port plug. Input signals such as door closed, locked, and emergency unlock are connected to the input port plug. The positive power supply signal on this plug is connected to the switches to provide power. Output signals such as buzzers and indicator lights are connected to the output plug. The negative power supply signal on this plug is connected to these devices to provide a circuit. The motor wires are connected to the motor interface plug.

[0037] After the electronic door controller is installed on the vehicle door, directly plug the external 2-wire female connector plug, input and output port plugs and motor plug into the corresponding sockets on the electronic door controller.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
