[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] See appendix Figure 1 The diagram shows a high-speed barrier gate controller connected to terminals via a rail-mounted relay in the prior art. The rail-mounted relay also needs to be connected to the controller via a cable. Manually completing a large amount of electrical wiring work is not only time-consuming, but the welding method is also inconvenient and unreliable. The large number of cables and terminals makes it easy to make mistakes during connection.

[0033] For the above issues, please refer to the appendix. Figure 2-4 As shown, this utility model provides an IO integrated circuit board, including a motherboard 10. The motherboard 10 is provided with several sets of wiring terminals 12. The IO line 300 includes a first plug 31 and a second plug 32. The first plug 31 and the second plug 32 can be directly inserted into the wiring terminals 12 to realize the connection between the motherboard 10 and the controller. The motherboard 10 is also equipped with plug-in relays, including a first relay 14 and a second relay 15. The first relay 14 is used to output a gate opening or closing signal to drive peripheral devices to open or close the gate, and the second relay 15 is used to output a light signal.

[0034] In a further embodiment, see Appendix Figure 5As shown, the terminal block 12 includes a first bent-pin terminal CN1, a second bent-pin terminal CN2, a third bent-pin terminal CN3, a fourth bent-pin terminal CN4, a fifth bent-pin terminal CN5, a sixth bent-pin terminal CN6, a first straight-pin terminal CN7, a second straight-pin terminal CN8, a first terminal plug CN9, a first terminal plug CN10, and a third straight-pin terminal CN11. The first bent-pin terminal CN1 is an external power supply output DC24V terminal, distributing externally input DC24V power to other devices and providing extended power supply capability. The second bent-pin terminal CN2 and the third bent-pin terminal CN3... All terminals are used to receive input signals. The second bent-pin terminal CN2 receives signals including reserved signals, restart signals, and gate opening / closing signals. The third bent-pin terminal CN3 receives signals including ground sensor signals, fire alarm signals, and infrared signals from peripheral devices. The fourth bent-pin terminal CN4 is the controller's DC24V output terminal, providing the controller's generated DC24V power for use by peripheral devices. The fifth bent-pin terminal CN5 is the output signal terminal, outputting system status signals (such as gate open position, fault alarm) to external devices. The sixth bent-pin terminal CN6 is for connecting external indicator lights. The signal terminals for the traffic lights are as follows: The first straight-pin terminal CN7 is the DC24V power input terminal. The main board receives the external DC24V power input through the first straight-pin terminal CN7, which is then isolated by fuse 16 and diode before being distributed to the components on the main board 10. The second straight-pin terminal CN8 is the barrier sensor terminal. The main board 10 connects to the barrier sensor through the second straight-pin terminal CN8 to detect the mechanical state of the barrier (such as derailment or jamming). The first terminal plug CN9 and the second terminal plug CN10 are the control signal input terminals. The controller connects to the first terminal plug CN9 and the second terminal plug CN10 respectively via I / O lines. Connect CN10 to receive input signals from peripheral devices and send corresponding feedback. The third straight-pin terminal 11 is the input DC12V power terminal, used to receive external DC12V power to power low-voltage loads (such as LED indicators and plug-in relay contacts). In this embodiment, the power supply voltage of the first relay 14 and the second relay 15 is 24VDC, and the voltage of the contacts is 12VDC. In this embodiment, the relays are integrated onto the circuit board, avoiding the problems of complex relay wiring and easy wiring errors. The connection method between components on the main board 10 is shown in the attached figure. Figure 5 As shown, the connection methods between components are all existing technologies, so they will not be described in detail here.

[0035] In a further embodiment, the first terminal plug CN9 is a connector of model KF2510-7P and the second terminal plug CN10 is a connector of model KF2510-9P. The functional descriptions and wiring instructions of their pins are shown in Table 1 and Table 2. By setting the first terminal plug CN9 and the second terminal plug CN10, the controller can be directly plugged into the first terminal plug CN9 and the second terminal plug CN10 through the IO line, which results in higher wiring efficiency and a more secure connection.

[0040] In a further embodiment, the motherboard 10 is also provided with a test switch 13, which is installed on the motherboard 10. The test switch 13 includes a rod release test switch 131, an infrared test switch 132, a fire protection test switch 133, a ground sensor test switch 134, and a jumper switch 135. The rod release test switch 131, the infrared test switch 132, the fire protection test switch 133, and the ground sensor test switch 134 are connected between the controller and the peripheral equipment. When the corresponding switch is closed, the controller will generate the corresponding test signal to the peripheral equipment to carry out the simulation test. The jumper switch 135 is connected to a plug-in relay and is used to switch the polarity of the input plug-in relay voltage. The switching voltage is + / -24VDC.

[0041] In a further embodiment, to facilitate opening and closing the gate in the event of controller failure, a first button switch 17 and a second button switch 18 are also provided on the main board 10. The first button switch 17 generates a gate closing signal, and the second button switch 18 generates a gate opening signal. The user can control the barrier gate machine through the signals generated by the first button switch 17 and the second button switch 18.

[0042] In a further embodiment, to facilitate equipment maintenance, a display unit is also provided on the motherboard 10. Each IO input / output port is equipped with a corresponding display unit. Each display unit consists of a current-limiting resistor and an LED connected in series. In this embodiment, at least 19 display units L1-L19 are included. The input signals of the corresponding ports of each group of display units are shown in Table 3. When a fault occurs on the equipment, it is only necessary to observe the corresponding LED without checking the underlying code, which is more convenient than using a multimeter for maintenance.
