As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
The invention provides an APM (automatic Train Management) vehicle door Control System, which is a structural schematic diagram of the APM vehicle door Control System as shown in figure 1 and comprises an automatic Train Control System (ATC), a Train Control Management System (TCMS) and an Electronic Door Controller (EDCU), wherein the input end of the Electronic Door Controller (EDCU) is provided with a hard wire interface and a network interface, the automatic Train Control System (ATC) is connected with the TCMS in a network manner, and the TCMS is connected with the EDCU in a network manner, so that the network connection between the automatic Train Control System (ATC) and the EDCU is realized; meanwhile, the automatic train control system (ATC) is also directly connected with an electronic gate controller (EDCU) in a hard wire mode. The output of EDCU and the motor drive circuit electric connection of door motor (M) are equipped with inside safety relay (K) on the motor drive circuit, by the break-make of inside safety relay (K) control motor drive circuit last normally open contact T, the control end of inside safety relay (K) also with train automatic control system (ATC) electric connection. Since the APM vehicle is usually designed with two doors on the same side, the EDCU1 and the EDCU2 are correspondingly arranged in the APM vehicle in the figure 1, and a cross control mode is adopted, so that the front door and the rear door of the APM vehicle can be opened or closed simultaneously only when the door opening and closing commands received by the EDCU1 and the EDCU2 are the same. The output end of the EDCU1 is connected with a first door motor (M1), a motor driving circuit of M1 is provided with two normally open contacts of T1 and T2, and the on-off states of T1 and T2 are controlled by a first internal safety relay (K1); correspondingly, the output end of the EDCU2 is connected with a second door motor (M2), a motor driving circuit of the M2 is provided with two normally open contacts of T3 and T4, and the on-off states of the T3 and the T4 are controlled by a second internal safety relay (K2). The control ends of the K1 and the K2 are electrically connected with the ATC, when the K1 and the K2 receive a gate enable hard wire signal sent by the ATC, the coils of the K1 and the K2 are electrified, so that two corresponding normally open contacts T1, T2, T3 and T4 are closed, and the motor driving circuits of the M1 and the M2 are switched on; m1 is then controlled by EDCU1 and M2 is controlled by EDCU2 to execute the open and close door command issued by the ATC.
The invention provides an APM vehicle door control method, which is realized based on the invention system and comprises the following steps:
step one, when the door opening and closing conditions are met, the ATC sends high-level door enabling hard-line signals to the K1 and the K2, the K1 and the K2 are activated, coils of the K1 and the K2 are electrified, two corresponding normally open contacts T1, T2, T3 and T4 are closed, and therefore the motor driving circuits of the M1 and the M2 are switched on.
And step two, the ATC sends a door opening and closing instruction of a network signal to the EDCU1 and the EDCU2 through the TCMS, and simultaneously, the ATC directly sends a door opening and closing instruction of a hard wire signal to the EDCU1 and the EDCU2 through hard wire lines.
Step three, the EDCU1 and the EDCU2 analyze the received signals, if the network signal is the same as the door opening and closing instruction of the hard wire signal, it indicates that the ATC and the entire control system operate normally, the door opening and closing instruction is correct, and the EDCU1 and the EDCU2 execute the door opening and closing instruction. If the network signal is different from the door opening and closing instruction of the hard wire signal, or only the network signal or the hard wire signal is received by the EDCU1 and the EDCU2, the control system has problems, such as an ATC system error, a hard wire line fault, a network communication fault and the like, and at the moment, the EDCU1 and the EDCU2 do not execute the door opening and closing instruction, but send an alarm to the TCMS and perform manual intervention processing.
And step four, after receiving the door lock in-place signal, the ATC sends a low-level door enabling hard wire signal to the K1 and the K2, the relays K1 and K2 lose power, the normally open contacts T1, T2, T3 and T4 are normally opened, the two motor loops are disconnected, and the phenomenon that when the door opening and closing conditions are not met, M1 and M2 are mistakenly operated, so that the APM door is mistakenly opened or closed is avoided, and safety danger is caused.
According to the invention, two control links of network connection and hard wire connection are set, a door opening and closing instruction of a network signal and a hard wire signal is sent to an Electronic Door Controller (EDCU) by an automatic train control system (ATC) at the same time, the door opening and closing instruction of the network signal and the hard wire signal is analyzed and compared by the Electronic Door Controller (EDCU), and the corresponding door opening and closing instruction is executed only when the door opening and closing instruction of the network signal and the hard wire signal are the same. Because the hard line circuit and the network circuit redundancy mode are adopted to cross control the two vehicle door relays on the same side, the safety and the reliability of vehicle door control are improved, the technical problem that the APM unmanned system can cause the misoperation of the APM vehicle door under the condition that the ATC fails is effectively solved, and the influence of the failure on the normal operation of the vehicle is reduced.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
