Eight marshalling trains are used = DTC * MC1 * TC * MC1 * TC * MC1 * MC2 * DTC. The power receiving method is DC750V third rail current receiving and receiving power. The maximum design speed of the car is 80km / h. The traction system is direct torque control. Electric braking is preferentially used when braking, and electric energy is fed back to the grid. When the electric braking force is insufficient, the air brake does not exceed the adhesion limit of the motor vehicle. Added under equal distribution. The car's brakes can be divided into commonly used brakes, all-used brakes, handle emergency brakes, and emergency brakes performed by the driver pressing the emergency brake button.
紧急制动是不考虑冲击率的纯空气制动(印度加尔各答地铁是闸瓦制动)，紧急制动的执行机构是制动***，同时车辆的电气部分要配备紧急制动安全环线电路来给该执行机构进行指令输入，制动***的紧急制动机构接收到电平信号指令后通过制动缸的充气推动闸瓦与轮对踏面进行接触达到紧急制动的目的。通常情况下，紧急制动安全环线一旦失电(低电平0V)，车辆立即施加紧急制动，直至停车。Emergency braking is pure air braking without considering the impact rate (the brakes of the Calcutta metro in India are brake shoes). The executive mechanism of the emergency braking is the braking system. At the same time, the electrical part of the vehicle must be equipped with an emergency braking safety loop circuit to give The actuator performs command input. After receiving the level signal command, the emergency braking mechanism of the braking system pushes the brake shoe into contact with the wheel tread surface through the inflation of the brake cylinder to achieve the purpose of emergency braking. Under normal circumstances, once the emergency braking safety ring line loses power (low-level 0V), the vehicle immediately applies emergency braking until it stops.

以国内某条成功运营多年的地铁车辆为例进行阐述，该紧急制动安全电路图如图1所示，其中，对附图1中的紧急制动安全环线的各个部分及操作功能进行说明：电源，紧急制动安全环线电路的电压等级为DC110V(DC77V～DC137.5V)，电源由单独设置在电器柜中的空气开关给出。负端，紧急制动安全环线电路的负端接入车辆上的接地开关箱中，最终汇到轴端接地，保证形成一个完整的电路。紧急制动安全环线电路正回路，正回路由紧急制动施加继电器EBAPR常开触点、信号***控制模块ATCC常开触点、警惕电路延时继电器DMTR常闭触点、方向手柄零位继电器NEUR常闭触点、88公里继电器SP88R常闭触点、重连紧急制动继电器常闭触点TEBBR、紧急制动按钮EBB、总风压力开关A10以及尾车继电器RCR常开触点串联组成。这些都是紧急制动安全环线电路中的重要逻辑部分，只有上述环节都处于正常工作状态，紧急制动安全环线电路正回路方可通路。正回路的连接方向是从激活端车辆到尾车为止，当然每一部分都是等电位。紧急制动安全环线电路负回路，同理，该回路的连接方向是从尾车开始，再回到激活端车辆，将上述的逻辑部分的不同触点再继续串联形成，最终接地。负载，不难看出，紧急制动施加继电器EBAPR以及每节车的网关阀GWV和智能阀SMV都成为该电路的负载部分。Take a domestic subway vehicle that has been in operation for many years as an example for illustration. The emergency brake safety circuit diagram is shown in Figure 1. Among them, the parts and operating functions of the emergency brake safety ring line in Figure 1 are described: power supply. The voltage level of the emergency braking safety ring circuit is DC110V (DC77V ~ DC137.5V), and the power supply is given by an air switch separately installed in the electrical cabinet. Negative end, the negative end of the emergency braking safety ring circuit is connected to the grounding switch box on the vehicle, and finally sinks to the shaft end to be grounded to ensure the formation of a complete circuit. Emergency brake safety loop circuit positive circuit, the positive circuit is provided by the emergency brake application relay EBAPR normally open contact, signal system control module ATCC normally open contact, alert circuit delay relay DMTR normally closed contact, directional handle zero relay NEUR Normally closed contact, 88 km relay SP88R normally closed contact, reconnected emergency brake relay normally closed contact TEBBR, emergency brake button EBB, total wind pressure switch A10, and tailgate relay RCR normally open contact are connected in series. These are important logic parts in the emergency braking safety ring circuit. Only the above links are in normal working state, and the emergency braking safety ring circuit can only pass through the positive loop. The connection direction of the positive circuit is from the active vehicle to the rear vehicle, of course, each part is equipotential. The emergency braking safety loop circuit has a negative loop. Similarly, the connection direction of the loop is from the tail car, and then back to the active end vehicle. The different contacts of the above logic part are continued to form in series, and finally grounded. Load, it is not difficult to see that the emergency brake application relay EBAPR and the gateway valve GWV and smart valve SMV of each vehicle have become the load part of the circuit.
触发紧急制动的条件，紧急制动安全环线电路上电通路为缓解紧急制动(配合零速停车和拉手柄快制缓解)，断路失电立即施加紧急制动。那么哪些条件能使得该回路断路而施加紧急制动呢？具体使得回路断路而施加紧急制动的条件可以包括以下至少之一：车辆在ATO控车的情况下，车辆速度超过所经区段的最大限速；司机松开警惕手柄5秒后触发紧急制 动；司机在车辆惰行的情况下将方向手柄回零位；人控车的情况下，车辆速度超过88km/h；车辆行驶过程中，司机按下紧急制动按钮(头尾车均可操作)；总风压力低于6bar，导致紧急制动所用风压不够。以上几点都能触发紧急制动，直至车辆停车，保证车辆行车安全。Conditions for triggering emergency braking. The power-on path of the emergency braking safety ring circuit is to relieve emergency braking (coordinated with zero-speed stop and pull handle quick-release mitigation), and the emergency braking is immediately applied when the power is cut off. So what conditions can make the circuit open and apply emergency braking? Specific conditions for making the circuit open and applying emergency braking may include at least one of the following: when the vehicle is controlled by the ATO, the vehicle speed exceeds the maximum speed limit of the section that it passes through; the driver triggers the emergency control after releasing the alert handle for 5 seconds When the vehicle is idling, the driver returns the steering handle to the zero position. In the case of a human-controlled vehicle, the vehicle speed exceeds 88km / h. During the driving of the vehicle, the driver presses the emergency brake button (both head and tail vehicles can operate) ; The total wind pressure is lower than 6bar, which results in insufficient wind pressure for emergency braking. The above points can trigger emergency braking until the vehicle is stopped to ensure the safety of the vehicle.
另外，继续参考附图1可知，该地铁车辆为四动两拖6节编组，编组形式为TC/MP/M1/M2/MP/TC，紧急制动的电气执行机构是制动的***的网关阀GWV和智能阀SMV，当这两个电磁阀所接入的电路失电后，即输入时0V时，其所控制的机械部分动作，车辆施加紧急制动。In addition, if you continue to refer to Figure 1, the subway vehicle is a four-moving, two-drag, six-section marshalling group with the format of TC / MP / M1 / M2 / MP / TC. The electric actuator for emergency braking is the gateway of the braking system. The valve GWV and the smart valve SMV, when the circuits connected to the two solenoid valves lose power, that is, when the input is 0V, the mechanical part controlled by them operates, and the vehicle applies emergency braking.
不难发现，网关阀GWV和智能阀SMV以及车辆配置的两个紧急制动施加继电器EBAPR同为并联关系，只要紧急制动安全环线得失电，它们也就同步的得失电。紧急制动施加继电器EBAPR本身的常开常闭触点用于其他功能电路中，用做TMS监控、牵引制动等***的反馈等。It is not difficult to find that the gateway valve GWV and smart valve SMV and the two emergency brake application relays EBAPR of the vehicle are also connected in parallel. As long as the emergency brake safety loop line loses power, they also gain and lose power simultaneously. The normally open and normally closed contact of the emergency brake application relay EBAPR itself is used in other functional circuits, and is used for feedback of TMS monitoring, traction braking and other systems.
上述的紧急制动安全回路从设计上是满足车辆正常的运行需要的。众所周知，制动***是城轨车辆最终要的部件，车辆遇到紧急情况司机的第一反应就是施加紧急制动，紧急制动安全环线电路设计的好坏决定着车辆运行是否安全，在不撞击前方物体的情况下以最快的瞬动性，尽量缩小制动距离，减少车辆和它物的损伤。The above-mentioned emergency braking safety circuit is designed to meet the normal running needs of the vehicle. As everyone knows, the braking system is the ultimate component of urban rail vehicles. The driver ’s first response to an emergency situation is to apply emergency braking. The design of the emergency braking safety ring circuit determines whether the vehicle runs safely and does not impact. In the case of the object in front, the braking distance is minimized to minimize the damage to the vehicle and other objects with the fastest transient.
但是，该电路只是单一的回路，如果中间某个或者多个逻辑部分工作失效，将会导致无法正常行车，即使操作多个旁路按钮屏蔽故障点也是不符合安全行车规程的。那么此时结果只有一个，那就是救援，救援程序一旦展开，不仅影响整条线路的运行计划，而且还必须对乘客进行疏散，严重影响乘客的出行效率。However, this circuit is only a single loop. If one or more of the logic sections in the middle fails, it will cause abnormal driving. Even if multiple bypass buttons are operated to shield the fault point, it is not in compliance with the safe driving regulations. Then there is only one result at this time, that is, rescue. Once the rescue procedure is launched, it will not only affect the operation plan of the entire line, but also evacuate passengers, which will seriously affect the travel efficiency of passengers.

图2为本发明实施例提供的一种轨道车辆紧急制动安全环线电路的原理示意图，参考附图2可知，本实施例提供了一种轨道车辆紧急制动安全环线电路，包括：电源、负端以及设置于电源与负端之间的主用安全线路和备用安全线路，主用安全线路贯穿设置于轨道车辆的头车与尾车上，备用安全线路贯穿设置于轨道车辆的头车与尾车上，并且，主用安全线路与备用安全线路通过第一模式开关SEBLBS进行切换连接，以实现通过主用安全线路或者备用安全线路对轨道车辆施加紧急制动操作。FIG. 2 is a schematic diagram of a rail vehicle emergency braking safety ring circuit according to an embodiment of the present invention. As can be seen with reference to FIG. 2, this embodiment provides a rail vehicle emergency braking safety ring circuit, which includes: a power supply, a negative Terminals and main safety lines and backup safety lines provided between the power source and the negative terminal. The main safety lines run through the head and tail cars of the rail vehicle, and the spare safety lines run through the head and tail cars of the rail vehicle. On the vehicle, the main safety line and the backup safety line are switched and connected through the first mode switch SEBLBS, so as to implement an emergency braking operation on the rail vehicle through the main safety line or the backup safety line.
其中，对于本实施例中的电源而言，紧急制动安全环线电路的电压等级均为为DC110V(DC77V～DC137.5V)，电源同样由单独设置在电器柜中的空气开关给出。而对于本实施例中的负端而言，紧急制动安全环线电路的负端接入车辆上的接地开关箱中，最终汇到轴端接地，保证形成一个完整的电路。Among them, for the power supply in this embodiment, the voltage levels of the emergency braking safety ring circuit are all DC110V (DC77V ~ DC137.5V), and the power supply is also given by an air switch separately provided in the electrical cabinet. For the negative terminal in this embodiment, the negative terminal of the emergency braking safety ring circuit is connected to the grounding switch box on the vehicle, and finally it is connected to the shaft terminal to be grounded to ensure that a complete circuit is formed.
需要注意的是，为了进一步增加该轨道车辆紧急制动安全环线电路使用的安全可靠性，该负端处增加了断负端逻辑功能，即当司机操作紧急制动按钮触发紧急制动的同时，相应的逻辑触点立即将该负端同步断开，保证紧急制动操作的执行能力。也即：负端连接有负端控制器，用于在对轨道车辆施加紧急制动操作时，控制负端断开与其他部件的连接。It should be noted that in order to further increase the safety and reliability of the rail vehicle emergency braking safety ring circuit, a logic function of negative negative terminal is added to the negative terminal, that is, when the driver operates the emergency braking button to trigger emergency braking, the corresponding The logic contact immediately disconnects the negative terminal synchronously to ensure the ability to perform emergency braking operations. That is, a negative terminal controller is connected to the negative terminal, and is used to control the negative terminal to disconnect from other components when an emergency braking operation is applied to a rail vehicle.
另外，紧急制动安全环线电路上电通路为缓解紧急制动(配合零速停车和拉手柄常用制动位缓解)，断路失电立即施加紧急制动。具体的，如下情况触发紧急制动：(1)车辆在ATP控车的情况下，车辆速度超过所经区段的最大限速；(2)司机松开警惕手柄后立即触发紧急制动；(3)司机在车辆惰行的情况下将方向手柄回零位；(4)司机操作司控器手柄紧急制动；(5)车辆行驶过程中，司机按下司机室内在不同位置分布的紧急制动按钮(头尾车均可操作)；(6)总风压力低于6bar，导致紧急制动所用风压不够。以上几点都能触发紧急制动，直至车辆停车，保证车辆行车安全。In addition, the power-on path of the emergency brake safety ring circuit is to alleviate emergency braking (coordinated with the zero-speed stop and the common braking position of the handle to ease the brake), the emergency braking is immediately applied when the power is cut off. Specifically, emergency braking is triggered as follows: (1) when the vehicle is under ATP control, the vehicle speed exceeds the maximum speed limit of the section it passes through; (2) the driver immediately triggers emergency braking after releasing the alert handle; 3) The driver returns the directional handle to the zero position when the vehicle is idling; (4) The driver operates the controller handle for emergency braking; (5) During the vehicle driving, the driver presses the emergency brakes distributed at different positions in the driver's room. Buttons (both head and tail vehicles can be operated); (6) The total wind pressure is lower than 6 bar, which causes insufficient wind pressure for emergency braking. The above points can trigger emergency braking until the vehicle is stopped to ensure the safety of the vehicle.
此外，在轨道车辆触发紧急制动操作时,首先采用主用安全线路施加紧急制动操作，当主用安全线路出现故障时，为了保证紧急制动操作的正常进行，可以通过第一模式开关SEBLBS切换至备用安全线路上，使得轨道车辆可以通过备用安全线路进行紧急制动操作。In addition, when an emergency braking operation is triggered by a rail vehicle, the emergency braking operation is first applied by the main safety line. When the main safety line fails, in order to ensure the normal operation of the emergency braking operation, it can be switched by the first mode switch SEBLBS. To the backup safety line, so that rail vehicles can perform emergency braking operations through the backup safety line.

Connection, thus realizing the emergency braking operation to the rail vehicle through the main safety line or the backup safety line, the direct rescue after the previous failure, and the current circuit switching, effectively increasing the redundancy of the emergency braking safety circuit Reliability, stability and reliability, reducing the chance of vehicles being rescued due to minor faults, improving the smoothness and smoothness of vehicle operation, reducing and avoiding the costs of rescue and vehicle maintenance, and ultimately benefiting from traveling passengers and improving subway operations And passenger travel efficiency.
图3为本发明实施例提供的主用安全线路的原理示意图；图4为本发明实施例提供的主用安全线路处于应急模式的原理示意图；在上述实施例的基础上，继续参考附图3-4可知，本实施例中对于主用安全线路的具体电路结构不做限定，本领域技术人员可以根据其实现的功能作用进行任意设置，较为优选的，该主用安全线路可以细分成两个小回路，将逻辑部分从头车开始， 经过中间车的过渡和交车再串联到尾车；同样，从尾车到头车的另一个小回路同理可据。重要的一点是，头车或者尾车的逻辑部分的不同触点分别用在不同的小回路中，一旦触发紧急，整个电路同时断电，保证指令输出的一致性。FIG. 3 is a schematic diagram of the principle of the main safety line according to the embodiment of the present invention; FIG. 4 is a schematic diagram of the principle of the main safety line in the emergency mode according to the embodiment of the present invention; based on the above embodiment, continue to refer to FIG. 3 It can be known that the specific circuit structure of the main safety line is not limited in this embodiment, and those skilled in the art can arbitrarily set according to the functions and functions realized by it.

图5为本发明实施例提供的备用安全线路的原理示意图，在上述实施例的基础上，继续参考附图5可知，本实施例中对于备用安全线路的具体电路结构不做限定，本领域技术人员可以根据其实现的功能作用进行任意设置，与主用安全线路相类似，备用安全线路包括：依次串联连接的紧急制动施加继电器并联单元、多个紧急制动按钮、头车继电器并联单元、冗余EBL旁路开关、负载以及紧急制动按钮动作继电器EBBR。FIG. 5 is a schematic diagram of the principle of a backup safety line provided by an embodiment of the present invention. Based on the foregoing embodiment, and referring to FIG. 5, it can be seen that the specific circuit structure of the backup safety line is not limited in this embodiment, and the technology in the art Personnel can make any settings according to the functions they implement.

为了保证线路工作的稳定可靠性，在通过备用安全线路对轨道车辆施加紧急制动操作时，利用备用安全线路和预设的运输管理***TMS对轨道车辆进行限速控制。In order to ensure the stability and reliability of the line work, when the emergency braking operation is applied to the rail vehicle through the backup safety line, the speed limit control of the rail vehicle is performed by using the backup safety line and the preset transportation management system TMS.
具体的，当主用安全线路和主用安全线路的应急模式都发生故障的情况下，此时司机操作第一模式开关SEBLBS切换到备用安全环线，注意，此时的车辆为非正常运行状态，必须通过TMS***协同配合进行限速运行，将乘客运行到下一站或者某一地点进行清客，而后车辆独立运行回段检查，在车辆运行过程中，如再遇到紧急情况，司机可以操作紧急制动按钮施加紧急制动。此状态下，不需要救援，不影响整条线路的运行。可以理解的是，理论上来讲，激活该模式的机率是很小的，上述所设计的电路已经安全可靠，此电路相当于增加了保险，提高车辆的稳定性、运营的畅通性。Specifically, when the emergency mode of both the main safety line and the main safety line fails, the driver operates the first mode switch SEBLBS to switch to the standby safety ring line at this time. Note that the vehicle at this time must be in an abnormal operating state. The TMS system cooperates with the speed limit operation to move passengers to the next station or a place to clear passengers, and then the vehicle independently runs back to check. During the operation of the vehicle, if an emergency occurs again, the driver can operate the emergency The brake button applies emergency braking. In this state, no rescue is needed and the operation of the entire line is not affected. It is understandable that, theoretically, the probability of activating this mode is very small. The circuit designed above is safe and reliable. This circuit is equivalent to increasing insurance, improving vehicle stability and smooth operation.
本实施例提供的轨道车辆紧急制动安全环线电路，可以实现如下效果：The rail vehicle emergency braking safety ring circuit provided by this embodiment can achieve the following effects:
(1)通过在电路中设置两个模式开关(第一模式开关SEBLBS和第二模 式开关EBLBS)，用于处理不同故障情况下，切换到不同的运行模式下，继续建立紧急制动安全环线，当某一紧急制动安全环线发生故障的时候，可以通过模式开关切换到另一安全环线，保证车辆顺利运行，同时不同的模式要配合有不同的限速，能最大程度的运行到下一站或者回库，保证线路顺畅运行。(1) By setting two mode switches (the first mode switch SEBLBS and the second mode switch EBLBS) in the circuit, it is used to deal with different fault situations, switch to different operating modes, and continue to establish an emergency brake safety loop, When a certain emergency braking safety ring fails, you can switch to another safety ring through the mode switch to ensure the smooth running of the vehicle. At the same time, different modes must cooperate with different speed limits to run to the next station to the greatest extent. Or go back to the warehouse to ensure the smooth operation of the line.
(2)通过电路中集成有三个相互独立的、贯穿整车的紧急制动安全环线(主用安全线路、备用安全线路以及主用安全线路的应急模式)，其中，部分线路为串联型环线，部分为并联型环线，并且要配合模式开关进行切换，且分激活端有效。这样由以前的故障后直接救援，到现在的回路切换，平滑过渡，有效地增加了紧急制动安全环线电路的冗余性、稳定性和可靠性，优点显而易见。(2) Through the circuit, three independent emergency braking safety loop lines (the emergency mode of the main safety line, the backup safety line, and the main safety line) that run through the vehicle are integrated. Some of the lines are series-type ring lines. Part of it is a parallel loop line, and it needs to be switched with the mode switch. In this way, the direct rescue after the previous failure, the current circuit switching, and the smooth transition effectively increase the redundancy, stability and reliability of the emergency braking safety ring circuit, and the advantages are obvious.
(3)增加了断负端逻辑的设计，可以有效地防止电路正端由于其他电源的串入导致紧急制动无法施加。要施加紧急制动的时候，使得电路正负两端同时断开，确保紧急制动的施加。(3) The logic design of the negative terminal is added, which can effectively prevent the emergency braking of the positive side of the circuit from being applied due to the intrusion of other power sources. When applying emergency braking, make both positive and negative ends of the circuit open at the same time to ensure the application of emergency braking.
(4)设计有多个紧急制动按钮，在操纵台、和司机室左右门两侧电器柜上均设置紧急制动按钮，方便司机及其他操作人员可以从司机室前窗玻璃、以及司机室门观望的同时便捷的施加紧急制动(以往项目仅在操纵台上设置一个紧急制动按钮)，提高了司机的可操作性和选择性，同时也保证了该功能的冗余性。(4) Designed with multiple emergency stop buttons, emergency stop buttons are provided on the console and electrical cabinets on both sides of the left and right doors of the driver's cab, so that drivers and other operators can access the front window glass of the driver's cab and the door of the driver's cab At the same time, wait and apply the emergency brake conveniently (the previous project only provided an emergency brake button on the console), which improves the operability and selectivity of the driver, and also guarantees the redundancy of this function.
