It should be noted that, the relay may be replaced by a target relay, where each piece of information included in the attribute information satisfies a corresponding preset condition.
When the attribute information comprises a safety level, the preset condition corresponding to the safety level is that the safety level is not greater than a target level; when the attribute information comprises loop voltage, the preset condition corresponding to the loop voltage is that the loop voltage is equal to the target voltage; when the attribute information comprises loop current, the preset condition corresponding to the loop current is that the loop current is not greater than the target current; when the attribute information comprises a power-on time sequence, a preset condition corresponding to the power-on time sequence is that the power-on time sequence lags behind the target power-on time; when the attribute information comprises a position, the preset condition corresponding to the position is that the position meets the preset position condition; when the attribute information comprises the function, the preset condition corresponding to the function is that the function meets the preset function condition.
It should be noted that, in order to have strong redundancy and ensure the running safety of the rail vehicle, the electronic logic control circuit includes a target contact and a target bypass contact. Wherein the target bypass contact is a replaceable contact of the target contact. When the target contact fails, the target bypass contact can be used to perform the corresponding function. By way of example in fig. 4, fig. 4 is a schematic diagram of an electronic logic control circuit for an alternative relay to the object provided by the embodiments of the present application. The contact in the electronic logic control circuit is used for replacing a train brake unreleasing relay and a train parking brake releasing relay in the figure 4, and the electronic logic control circuit is respectively provided with a corresponding bypass contact 1 and a corresponding bypass contact 2.
In addition, the electronic logic control device is provided with the photoelectric isolator which is used for carrying out photoelectric isolation on the input and the output of the electronic logic control device, so that the single-point damage fault is prevented from spreading, and the reliability is high.
It should be noted that, in particular, the electronic logic control devices in the rail vehicle are distributed. In specific implementation, a chassis (generally adopting a standard 3U chassis) is arranged in an electrical cabinet of each vehicle, and the electronic logic control device is packaged in the 3U chassis. The electronic logic control devices in all vehicles control the circuits of all vehicles, the functions are mutually independent, and the respective logic control functions are realized. The device equipment adopts CAN network to communicate, and realizes data interaction with the train control and management system network through MVB or Ethernet; the redundant design mode of two chassis is adopted in the two head cars, namely two redundant electronic logic control devices are arranged in the two head cars of the railway vehicle; a photoelectric isolator is arranged between the two electronic logic control devices with redundant designs to prevent the other electronic logic control device from burning due to the fault caused by the short circuit of one electronic logic control device. And each device is provided with an encoder, and the code identification of each compartment can be carried out through the code setting. In addition, the board card in each electronic logic control device is a double-board card, and has very strong fault tolerance. Because the redundant board cards have the same and independent functions, the case and the board cards with the same functions can be interchanged. The power panel of the electronic logic control device has the functions of output over-voltage and under-voltage protection, over-temperature protection, output overload protection, short-circuit protection, fault self-recovery and the like, and can automatically perform whole-group switching if any one power supply fails.
In specific implementation, the logic control during the operation of the rail train is as follows: the control between the redundant electronic logic control circuit and the board card adopts a reasonable main/standby logic switching mechanism and a state arbitration mechanism, so that disordered main/standby competition is avoided. When the target contact in the electronic logic control circuit has no signal output, the target bypass contact can output, and further when the output signal of the target bypass contact is invalid, the target bypass contact is switched to another electronic logic control circuit, so that the double redundancy of the output circuit is increased. In consideration of automatic implementation of redundancy of the electronic logic control circuit, a communication mode of a communication CAN/Ethernet is arranged between the chassis, and when any fault such as power supply fault, loss of life signals, output short circuit or output open circuit occurs in a single group of control systems, the single group of control systems is automatically switched to another electronic logic control circuit. In specific implementation, due to the fact that communication exists between the electronic logic control circuits, when two board cards in one electronic logic control circuit lose life signals at the same time, the delay 5s is switched to the other electronic logic control circuit, and the train operation is not affected by the switching action, so that the hot switching function is achieved. In addition, after the redundant points are switched, the driver reports the fault to the vehicle operation center under the condition of not influencing the vehicle operation, and if the other board card of the single machine is redundant, the vehicle can normally drive when the operation is not influenced. When the host is switched, the host is operated to the terminal station and then the garage is taken into consideration for maintenance, so that the operation to midway parking rescue is avoided.
It should be noted that after a board card fails once, a vehicle must be able to complete a task of moving passengers to a terminal, and after a redundant chassis fails for the second time, the vehicle must be able to safely stop, and it should be noted that the above-mentioned vehicle mostly adopts a virtual interface mode based on unmanned driving, but in consideration of special situations, when the vehicle does not move to the terminal or stop at the station, a set of key functions on the rail vehicle are controlled by a physical entity, which cannot be trusted by software, a virtual interface and remote operation, and when a rescuer gets on the vehicle, the vehicle can be quickly dragged and moved by operating the physical entity control, so as to avoid affecting the public transportation sequence. When unmanned, to the trouble that appears, accessible vehicle bottom wireless communication system sends trouble information to subway operation center.
