Abstract

A coupled train air compressor start-stop control method. A TCMS controls the start-stop of each air compressor; and, when the accumulated working time of each air compressor exceeds a second time threshold value and the total air pressure of the coupled train reaches a set value, the air compressors are stopped. The TCMS continuously monitors the total air pressure of the coupled train. When the total air pressure of the coupled train decreases to be lower than a second set value, the TCMS controls all the air compressors on the coupled train to simultaneously start to deliver compressed air so as to ensure that the total air pressure of the coupled train is kept within a pressure range capable of ensuring the normal operation of the coupled train. The working time of each air compressor can be relatively balanced, so that an excessively long working time of a certain air compressor is prevented, and meanwhile, it is ensured that each air compressor can work for a set time, thus ensuring that air compressor oil can reach a certain temperature so as to prevent emulsification of the air compressor oil. Also disclosed are a coupled train air compressor start-stop control system and a coupled train.

Description

重联列车及其空压机启停控制方法、***Start and stop control methods and systems for heavy-duty trains and their air compressors 技术领域Technical field
本发明涉及轨道交通技术领域，特别是一种重联列车及其空压机启停控制方法、***。The invention relates to the technical field of rail transit, in particular to a method and system for starting and stopping a heavy-duty train and its air compressor.
背景技术Background technique
在重联列车空压机启停***中，一旦重联列车中某一列车单元的空压机发生故障，将可能直接导致该列车单元内总风压力下降到风压下限值以下，甚至导致重联列车无法正常运行，因此有必要对该种运行形式的空压机控制方法进行研究，以实现在整个重联列车上对空压机进行控制，使空压机能够正常可靠地运行，保证机组的使用寿命不受影响。In the air compressor start-stop system of a heavy-duty train, once the air compressor of a certain train unit in the heavy-duty train fails, it may directly cause the total wind pressure in the train unit to drop below the lower wind pressure limit, or even cause The heavy-duty train cannot operate normally, so it is necessary to study the air compressor control method in this operation form to control the air compressor on the entire heavy-duty train so that the air compressor can operate normally and reliably to ensure The service life of the unit is not affected.
城轨车辆多为固定编组列车或固定重联编组列车，其空压机启停控制大部分采用单双日控制原则，如现有技术中的一种重联城轨列车空压机的控制方法(授权公告号CN102490740B)采用的就是单双日的控制方式，此种控制方式一方面可以保证空压机的工作率，降低空压机油乳化的概率，另一方面可以确保列车所有空压机工作时间均衡，方便列车维修保养计划安排；但该种控制方法通过TCMS(即列车控制管理***)进行控制，只适用于确定编组的重联列车，并不适用于不定编组重联运行的车辆。不定编重联列车主要体现为车辆为不定编，由于不定编组重联列车的车辆编组号、车辆顺序及长度均具有不确定性，如果采用与固定编组列车或固定重联编组列车相同或相似的空压机启停控制方法，可能会导致某些车辆上的空压机运行时间过长，而另外一些车辆上的空压机运行时间过短；另一方面，当编组长度改变，重联列车上的空压机数量多于空压机启停控制逻辑中规定的数量时，可能会引起控制混乱，无法保证单台空压机正常运行时间及工作效率，进而导致空压机油乳化等问题。Urban rail vehicles are mostly fixed trains or fixed heavy-duty trains, and most of their air compressor start and stop controls adopt the odd-even day control principle, such as a control method for the air compressor of heavy-duty urban rail trains in the prior art. (Authorization Announcement No. CN102490740B) adopts an odd-even day control method. On the one hand, this control method can ensure the working rate of the air compressor and reduce the probability of air compressor oil emulsification. On the other hand, it can ensure that all air compressors in the train The working hours are balanced to facilitate the arrangement of train maintenance plans; however, this control method is controlled through TCMS (Train Control Management System), which is only applicable to reconnected trains with determined formations, and is not suitable for vehicles with reconnected operations in indefinite formations. The main manifestation of the irregular formation of heavy-duty trains is that the vehicles are in an irregular formation. Since the vehicle composition number, vehicle sequence and length of the irregular formation of heavy-duty trains are uncertain, if the same or similar trains are used as fixed formation trains or fixed heavy-duty formation trains, The air compressor start-stop control method may cause the air compressor running time on some vehicles to be too long, while the air compressor running time on other vehicles is too short; on the other hand, when the marshalling length changes, the multiple trains When the number of air compressors on the air compressor is more than the number specified in the air compressor start-stop control logic, it may cause control chaos and cannot guarantee the normal operating time and working efficiency of a single air compressor, which may lead to problems such as air compressor oil emulsification. .
发明内容Contents of the invention
本发明所要解决的技术问题是，针对现有技术不足，提供一种重联列车及其空压机启停控制方法、***，防止重联列车上的空压机运行时间过长，同时防止空压机油乳化。The technical problem to be solved by the present invention is to provide a method and system for starting and stopping the reconnected train and its air compressor to prevent the air compressor on the reconnected train from running for too long and prevent the air compressor from running too long in view of the shortcomings of the existing technology. Press oil emulsification.
为解决上述技术问题，本发明所采用的技术方案是：一种重联列车空压机启停控制方法，包括以下步骤：In order to solve the above technical problems, the technical solution adopted by the present invention is: a method for starting and stopping the air compressor of a heavy-duty train, which includes the following steps:
S1、重联列车激活后，初始化i为1；S1. After the reconnection train is activated, initialize i to 1;
S2、判断重联列车总风压力是否低于第一设定值，若是，进入步骤S3；S2. Determine whether the total air pressure of the heavy-duty train is lower than the first set value. If so, proceed to step S3;
S3、将第i台空压机设置为主空压机，控制所述主空压机工作；S3. Set the i-th air compressor as the main air compressor and control the operation of the main air compressor;
S4、判断总风压力是否达到目标值，若是，关闭本次工作的所有空压机，并进入步 骤S6；否则，判断主空压机持续工作时长是否大于或等于第一时间阈值t1，若是，进入步骤S5；S4. Determine whether the total air pressure reaches the target value. If so, turn off all air compressors working this time and enter step S6; otherwise, determine whether the continuous working time of the main air compressor is greater than or equal to the first time threshold t1. If so, Enter step S5;
S5、启动第i+1台空压机，返回步骤S4；S5. Start the i+1 air compressor and return to step S4;
S6、判断主空压机累计工作时长是否大于或等于第二时间阈值，若否，则返回步骤S4；若是，则i的值加1，进入步骤S7；S6. Determine whether the cumulative working time of the main air compressor is greater than or equal to the second time threshold. If not, return to step S4; if yes, add 1 to the value of i and enter step S7;
S7、判断i的值是否大于N，若否，则返回步骤S2；若是，则关闭所有空压机；其中N为重联列车的空压机数量。S7. Determine whether the value of i is greater than N. If not, return to step S2; if so, turn off all air compressors; where N is the number of air compressors on the reconnect train.
本发明中，重联列车激活后，当重联列车总风压力低于第一设定值时，启动主空压机。若设定周期内主空压机持续工作时间达到第一时间阈值，但所述总风压力未达到目标值，此时启动下一台空压机(第i+1台空压机)，第i+1台空压机与主空压机同时工作，确保一定时间内总风压力可以达到目标值，以免影响发车周期；当主空压机持续工作时间达到第一时间阈值，且总风压力达到目标值，此时为了确保主空压机的正常工作时长，防止主空压机因工作时间过短导致的空压机油乳化，需要让主空压机继续工作(即在下一次打风时，仍然由主空压机打风)，并在设定周期内主空压机累计工作时间达到第二时间阈值，且总风压力达到目标值时，设置下一台空压机为主空压机，最终，在重联列车的所有空压机累计工作时间均达到第二阈值，且总风压力达到目标值时，关闭所有空压机，结束当前控制过程。本发明确保了重联列车激活后，每台空压机的工作时间相对均衡，且每台空压机的累计工作时间均会达到第二时间阈值，因此可以防止重联列车某些空压机工作时间过短，进而防止出现空压机油乳化的问题。In the present invention, after the heavy-duty train is activated, when the total air pressure of the heavy-duty train is lower than the first set value, the main air compressor is started. If the continuous working time of the main air compressor reaches the first time threshold within the set period, but the total air pressure does not reach the target value, the next air compressor (i+1th air compressor) is started at this time, and the i+1 air compressors work simultaneously with the main air compressor to ensure that the total air pressure can reach the target value within a certain period of time to avoid affecting the departure cycle; when the main air compressor's continuous working time reaches the first time threshold, and the total air pressure reaches Target value. At this time, in order to ensure the normal working time of the main air compressor and prevent the emulsification of the air compressor oil caused by the short working time of the main air compressor, it is necessary to allow the main air compressor to continue working (that is, during the next blow, The main air compressor still blows the air), and when the cumulative working time of the main air compressor reaches the second time threshold within the set period, and the total air pressure reaches the target value, the next air compressor is set as the main air compressor. , Finally, when the cumulative working time of all air compressors in the heavy-duty train reaches the second threshold and the total wind pressure reaches the target value, all air compressors are turned off and the current control process ends. The invention ensures that after the reconnection train is activated, the working time of each air compressor is relatively balanced, and the cumulative working time of each air compressor will reach the second time threshold, so it can prevent some air compressors of the reconnection train from The working time is too short to prevent the problem of air compressor oil emulsification.
本发明中，为了简化空压机编号过程，重联列车的N台空压机编号顺序与重联列车各节车编组顺序对应。例如，编号为1的空压机，即重联列车第1节车内的空压机，编号为2的空压机，即重联列车第2节车内的空压机，依此类推。In the present invention, in order to simplify the air compressor numbering process, the numbering sequence of the N air compressors of the heavy-duty train corresponds to the grouping sequence of each car of the heavy-duty train. For example, the air compressor numbered 1 is the air compressor in the first car of the multiplex train, the air compressor numbered 2 is the air compressor in the second car of the multiplex train, and so on.
本发明中，为了进一步保证重联列车断激活之前正常工作，同时简化空压机启停控制过程，步骤S7中，关闭所有空压机后，进入同时启停控制模式；所述同时启停控制模式实现过程包括：判断所述总风压力是否低于第二设定值，若是，则启动所有空压机，当所述总风压力达到目标值时，关闭所有空压机。In the present invention, in order to further ensure normal operation before the reconnection train is activated and simplify the start-stop control process of the air compressor, in step S7, after turning off all air compressors, the simultaneous start-stop control mode is entered; the simultaneous start-stop control The mode implementation process includes: determining whether the total air pressure is lower than the second set value; if so, starting all air compressors; when the total air pressure reaches the target value, turning off all air compressors.
本发明中，为了更加准确的监测重联列车的总风压力，将所述重联列车总风压力设定为重联列车各节车有效压力信号的平均值。本发明所指的有效压力信号，是指压力信号在压力采集装置(例如压力传感器)的量程范围内。实际运用中，一般排除最低及最高有效压力信号，取剩余有效压力信号的平均值作为总风压力。In the present invention, in order to more accurately monitor the total wind pressure of the multiplex train, the total wind pressure of the multiplex train is set to the average value of the effective pressure signals of each car of the multiplex train. The effective pressure signal referred to in the present invention means that the pressure signal is within the range of the pressure acquisition device (such as a pressure sensor). In practical applications, the lowest and highest effective pressure signals are generally excluded, and the average of the remaining effective pressure signals is taken as the total wind pressure.
本发明中，为了确保网络故障状态下重联列车断激活之前可以正常工作，当重联列车进入紧急牵引模式后，若重联列车某节车的总风压力下降至第三设定值，则启动重联列车的所有空压机，当该节车的总风压力达到目标值时，关闭重联列车的所有空压机。重联列车某节车的总风压力是指该节车内的压力检测装置(如压力调节器)采集到的压力信号。In the present invention, in order to ensure that the reconnected train can operate normally before being activated under network failure, when the reconnected train enters the emergency traction mode, if the total wind pressure of a certain car of the reconnected train drops to the third set value, then Start all air compressors of the heavy-duty train, and when the total air pressure of the train reaches the target value, turn off all the air compressors of the heavy-duty train. The total wind pressure of a certain car of a heavy-duty train refers to the pressure signal collected by the pressure detection device (such as a pressure regulator) in the car.
不难理解，本发明中，第一设定值、第二设定值、第三设定值均小于目标值。本发明中，第一设定值＞第二设定值＞第三设定值。It is easy to understand that in the present invention, the first set value, the second set value, and the third set value are all smaller than the target value. In the present invention, first set value>second set value>third set value.
作为一个发明构思，本发明还提供了一种重联列车空压机启停控制***，其包括：As an inventive concept, the present invention also provides a start-stop control system for air compressors of heavy-duty trains, which includes:
多个压力采集装置，分别设置于重联列车的各节车内；Multiple pressure collection devices are installed in each car of the heavy-duty train;

当重联列车网络出现故障时，为了确保重联列车断激活之前正常工作，本发明的重联列车空压机启停控制***还包括设置于重联列车各节车内的压力调节器；当重联列车进入紧急牵引模式后，若重联列车某节车的总风压力下降至第三设定值，则该节车内的压力调节器启动重联列车的所有空压机，当该节车的总风压力达到目标值时，该节车内的压力调节器关闭重联列车的所有空压机。When a failure occurs in the reconnection train network, in order to ensure normal operation before the reconnection train is disconnected and activated, the air compressor start-stop control system of the reconnection train of the present invention also includes a pressure regulator installed in each car of the reconnection train; when After the heavy-duty train enters the emergency traction mode, if the total air pressure of a certain car of the heavy-duty train drops to the third set value, the pressure regulator in the car starts all the air compressors of the heavy-duty train. When the total air pressure of the train reaches the target value, the pressure regulator in the train turns off all air compressors of the heavy train.
重联列车每节车内设置有两个压力调节器，两个压力调节器互为冗余，以确保重联列车网络出现故障时，至少有一个压力调节器可以正常工作，进而保障重联列车正常运行。There are two pressure regulators in each car of the heavy-duty train. The two pressure regulators are redundant to ensure that when the heavy-duty train network fails, at least one pressure regulator can work normally, thus ensuring the safety of the heavy-duty train. normal operation.
本发明中，为了保证空压机供给空气制动***用风设备的空气质量，重联列车每节车内的干燥器与对应车内的空压机同步工作。In the present invention, in order to ensure the air quality supplied by the air compressor to the wind equipment of the air brake system, the dryer in each car of the heavy-duty train works synchronously with the air compressor in the corresponding car.

实施例1Example 1
图1为本发明实施例对重联列车空压机进行单独启停控制的流程图。图1提供的流程图为一个设定周期内，TCMS***对重联列车空压机进行单独启停控制的流程。具体实现过程包括：Figure 1 is a flow chart of the individual start and stop control of the air compressor of the heavy-duty train according to the embodiment of the present invention. The flow chart provided in Figure 1 shows the process for the TCMS system to individually start and stop the air compressor of the heavy-duty train within a set period. The specific implementation process includes:
S1、重联列车激活后，控制程序开始，初始化i为1；S1. After the reconnection train is activated, the control program starts and i is initialized to 1;
S2、判断总风压力是否低于第一设定值，若是，则进入步骤S3；否则，重复步骤S2；S2. Determine whether the total air pressure is lower than the first set value. If so, proceed to step S3; otherwise, repeat step S2;

If so, turn off all air compressors working this time and enter step S6; otherwise, determine whether the continuous working time of the main air compressor is greater than or equal to the first time threshold t1. If so, Enter step S5; if the main air compressor continues to work for less than the first time threshold t1, repeat step S4;

S7、判断i的值是否大于N，若否，则返回步骤S2；若是，则关闭所有空压机；其中N为重联列车的空压机数量。S7. Determine whether the value of i is greater than N. If not, return to step S2; if so, turn off all air compressors; where N is the number of air compressors on the reconnect train.
本实施例的控制方法，是在重联列车网络正常的情况下执行的。The control method in this embodiment is executed when the reconnection train network is normal.
本实施例中，主空压机持续工作时间达到第一时间阈值时，若重联列车总风压力未达到目标值，此时为了防止总风压力上升太慢，导致重联列车启动慢，开启下一台空压机， 与主空压机一起工作，使重列列车总风压力快速上升。主空压机持续工作时间达到第一时间阈值时，若重联列车总风压力达到目标值，此时为了保证主空压机润滑油达到不易乳化的温度，防止主空压机润滑油未达到设定温度即关闭主空压机，本实施例选择让主空压机在下一次打风时继续工作(本次打风主空压机关闭)，直至主空压机累计工作时间达到第二时间阈值时，关闭主空压机。本实施例中的主空压机继续工作，是指在下一次打风时，仍然由主空压机打风。In this embodiment, when the continuous working time of the main air compressor reaches the first time threshold, if the total air pressure of the multiplex train does not reach the target value, at this time, in order to prevent the total air pressure from rising too slowly, causing the multiplex train to start slowly, turn on The next air compressor works together with the main air compressor to quickly increase the total air pressure of the heavy train. When the continuous working time of the main air compressor reaches the first time threshold, if the total air pressure of the reconnected train reaches the target value, at this time, in order to ensure that the lubricating oil of the main air compressor reaches a temperature that is not easy to emulsify, and prevent the lubricating oil of the main air compressor from not reaching the The main air compressor is turned off when the temperature is set. In this embodiment, the main air compressor is selected to continue working during the next blow (the main air compressor is turned off this time) until the cumulative working time of the main air compressor reaches the second time When the threshold is exceeded, the main air compressor is turned off. In this embodiment, the main air compressor continues to work, which means that the main air compressor will still blow the air the next time.
本实施例中，第二时间阈值的设定，以保证空压机的润滑油温度可以升高到不易乳化的温度为准，降低空压机油乳化的几率。In this embodiment, the second time threshold is set to ensure that the lubricating oil temperature of the air compressor can be raised to a temperature that is difficult to emulsify, thereby reducing the probability of emulsification of the air compressor oil.
本实施例中，第一时间阈值设定为10min，第二时间阈值设定为15min。第一设定值为850kPa。主空压机累计工作时间达到15min时，其润滑油温度可以上升到不易乳化的温度，防止空压机油乳化，且主空压机累计工作时间达到15min，可以满足打风结束条件(即重联列车总风压力达到目标值)时，可以关闭主空压机，防止主空压机工作时间过长。In this embodiment, the first time threshold is set to 10 minutes, and the second time threshold is set to 15 minutes. The first setting value is 850kPa. When the cumulative working time of the main air compressor reaches 15 minutes, the lubricating oil temperature can rise to a temperature that is not easy to emulsify to prevent the emulsification of the air compressor oil, and the cumulative working time of the main air compressor reaches 15 minutes, which can meet the conditions for the end of blowing (i.e. heavy blowing). When the total air pressure of the train reaches the target value), the main air compressor can be shut down to prevent the main air compressor from working for too long.
本实施例中，空压机工作，是指空压机打风。In this embodiment, the operation of the air compressor means that the air compressor blows air.
本实施例中，重联列车的N台空压机编号顺序与重联列车各节车编组顺序对应。例如，编号为1的空压机，即重联列车第1节车内的空压机，编号为2的空压机，即重联列车第2节车内的空压机，依此类推，编号为N的空压机，即重联列车第N节车(即重联列车最后一节车)内的空压机。In this embodiment, the number sequence of the N air compressors of the heavy-duty train corresponds to the grouping sequence of each car of the heavy-duty train. For example, the air compressor numbered 1 is the air compressor in the first car of the multiplex train, the air compressor numbered 2 is the air compressor in the second car of the multiplex train, and so on. The air compressor numbered N is the air compressor in the Nth car of the multiplex train (i.e., the last car of the multiplex train).
本实施例中，重联列车空压机的编号顺序也可以由重联列车控制***给定，即重联列车控制***对重联列车的所有空压机编号，再按照编号顺序控制各空压机的启停。此种编号方式与重联列车编组顺序可以相同，也可以不同。In this embodiment, the numbering sequence of the air compressors of the heavy-duty train can also be given by the heavy-duty train control system. That is, the heavy-duty train control system numbers all the air compressors of the heavy-duty train, and then controls each air compressor according to the numbering sequence. Start and stop the machine. This numbering method may be the same as or different from the grouping order of heavy-duty trains.
当重联列车所有空压机累计工作时间均超过第二时间阈值(15min)，且重联列车总风压力达到设定值时，转为TCMS控制所有空压机同时启停的控制模式。When the cumulative working time of all air compressors in the heavy-duty train exceeds the second time threshold (15 minutes) and the total air pressure of the heavy-duty train reaches the set value, it will switch to the control mode in which TCMS controls all air compressors to start and stop at the same time.
TCMS控制所有空压机同时启停的控制模式实现过程包括：判断总风压力是否低于第二设定值，若是，则同时启动所有空压机，当总风压力达到目标值时，同时关闭所有空压机。The control mode implementation process of TCMS controlling all air compressors to start and stop at the same time includes: judging whether the total air pressure is lower than the second set value, if so, starting all air compressors at the same time, and when the total air pressure reaches the target value, shutting down at the same time All air compressors.
本实施例中，第二设定值设定为800kPa。In this embodiment, the second setting value is set to 800kPa.
本实施例中，重联列车总风压力设定为重联列车各节车有效压力信号的平均值。有效压力信号是指压力信号在量程范围内。例如，重联列车第1节车有效压力为P1，第2节车有效压力为P1，……，第N节车有效压力为PN，则理论上的总风压力可以通过公式Pm＝(P1+P2+……+PN)/N计算获得。为了进一步提高总风压力计算精度，一般排除最 低及最高有效压力信号，取剩余有效压力信号的平均值作为总风压力，假设P1为最高(最大)的有效压力信号，PN为最低(最小)的有效压力信号，则最终的总风压力可以通过公式Pm＝(P2+……+PN-1)/(N-2)计算获得。In this embodiment, the total wind pressure of the heavy-duty train is set to the average value of the effective pressure signals of each car of the heavy-duty train. The effective pressure signal means that the pressure signal is within the range. For example, the effective pressure of the first car of a heavy-duty train is P1, the effective pressure of the second car is P1,..., and the effective pressure of the Nth car is PN, then the theoretical total wind pressure can be calculated by the formula Pm=(P1+ P2+……+PN)/N is calculated and obtained. In order to further improve the calculation accuracy of the total wind pressure, the lowest and highest effective pressure signals are generally excluded, and the average of the remaining effective pressure signals is taken as the total wind pressure. Assume that P1 is the highest (maximum) effective pressure signal and PN is the lowest (minimum) Effective pressure signal, the final total wind pressure can be calculated by the formula Pm=(P2+...+PN-1)/(N-2).
当网络故障，重联列车进入紧急牵引模式后，若重联列车某节车的总风压力下降至第三设定值，则启动重联列车所有空压机，当该节车的总风压力达到目标值时，关闭重联列车所有空压机。When the network fails and the heavy-duty train enters the emergency traction mode, if the total air pressure of a certain car of the heavy-duty train drops to the third set value, all air compressors of the heavy-duty train will be started. When the total air pressure of the car When the target value is reached, all air compressors of the heavy train will be turned off.
本实施例中，第三设定值为750kPa。In this embodiment, the third setting value is 750kPa.
本实施例中，目标值为1000kPa。In this embodiment, the target value is 1000kPa.
为了保证空压机供给空气制动***用风设备的空气质量，在任何情况下，重联列车各节车内的干燥器都将保持同该节车内的空压机同步工作。例如，当重联列车第i节车内的空压机启动时，第i节车内的干燥器同步启动。In order to ensure the air quality that the air compressor supplies to the wind equipment of the air brake system, under any circumstances, the dryers in each car of the heavy-duty train will keep working synchronously with the air compressor in that car. For example, when the air compressor in the i-th car of a heavy-duty train starts, the dryer in the i-th car starts simultaneously.
本实施例中，设定周期为一天。In this embodiment, the set period is one day.
本实施例中，重联列车激活后，TCMS***先采用上述步骤S1～S7的过程(即图1的过程)控制各台空压机的启停，当每台空压机均累计工作时间均超过第二时间阈值，且重联列车总风压力达到设定值时，关闭空压机。TCMS对重联列车的总风压力持续进行监控。关闭空压机后，重联列车的总风压力会下降，为了保证重联列车断激活之前继续正常运行，当重联列车总风压力下降到低于第二设定值时，TCMS***控制重联列车所有空压机同时启动打风，以确保重联列车的总风压力维持在可保证重联列车正常运行的压力范围内。在重联列车从激活到断激活的时间周期内，上述步骤S1～S7的过程(即图1的过程)只执行一次，该时间周期的其余时间均采用所有空压机同时启停的控制模式。该控制过程的前提是重联列车的网络正常，TCMS***可以正常工作。In this embodiment, after the reconnection train is activated, the TCMS system first uses the above-mentioned steps S1 to S7 (i.e., the process in Figure 1) to control the start and stop of each air compressor. When the accumulated working time of each air compressor is equal to When the second time threshold is exceeded and the total air pressure of the heavy-duty train reaches the set value, the air compressor is turned off. TCMS continuously monitors the total wind pressure of heavy-duty trains. After turning off the air compressor, the total air pressure of the heavy-duty train will drop. In order to ensure that the heavy-duty train continues to operate normally before the shutdown is activated, when the total air pressure of the heavy-duty train drops below the second set value, the TCMS system controls the heavy-duty train. All the air compressors of the multiplex train start blowing air at the same time to ensure that the total air pressure of the multiplex train is maintained within the pressure range that can ensure the normal operation of the multiplex train. During the time period from activation to deactivation of the reconnect train, the process of steps S1 to S7 (i.e., the process in Figure 1) is only executed once. The rest of the time period adopts the control mode of starting and stopping all air compressors at the same time. . The premise of this control process is that the network of the reconnection train is normal and the TCMS system can work normally.
一旦重联列车的网络出现故障，由于TCMS***无法获取各节车的压力数据，此时需启用设置于重联列车各节车内的压力调节器控制各节车内空压机的启停，保证重联列车正常运行。Once the network of the heavy-duty train fails, since the TCMS system cannot obtain the pressure data of each car, the pressure regulator installed in each car of the heavy-duty train needs to be activated to control the start and stop of the air compressor in each car. Ensure the normal operation of reconnection trains.
实施例2Example 2
本实施例提供了一种对应于上述实施例1的重联列车空压机启停控制***，包括：This embodiment provides a start-stop control system for air compressors of heavy-duty trains corresponding to the above-mentioned Embodiment 1, including:
多个压力采集装置，分别设置于重联列车的各节车内；Multiple pressure collection devices are installed in each car of the heavy-duty train;
处理单元，与所述多个压力采集装置通信连接，且被配置为用于实现上述实施例1方法的步骤。The processing unit is communicatively connected with the plurality of pressure collection devices, and is configured to implement the steps of the method in Embodiment 1 above.
本实施例中，压力采集装置为压力传感器，压力传感器为4～12mA电流型压力传感 器，4mA对应0bar(1bar＝100000Pa)，12mA对应12bar。重联列车的每一节车上配置1个压力传感器。重联列车的控制***(TCMS)通过采集压力传感器的模拟信号对总风压力Pm进行监控。在列车重联情况下，TCMS取各车有效压力信号(压力信号在量程范围内)的平均值作为重联列车的总风压力值。In this embodiment, the pressure acquisition device is a pressure sensor, and the pressure sensor is a 4-12mA current type pressure sensor. 4mA corresponds to 0bar (1bar=100000Pa), and 12mA corresponds to 12bar. Each car of the heavy-duty train is equipped with a pressure sensor. The train control system (TCMS) monitors the total wind pressure Pm by collecting analog signals from the pressure sensor. In the case of train reconnection, TCMS takes the average value of the effective pressure signals of each train (the pressure signal is within the measurement range) as the total wind pressure value of the reconnection train.
本实施例的重联列车空压机启停控制***还包括设置于重联列车各节车内的压力调节器。当重联列车进入紧急牵引模式后，若重联列车某节车的总风压力下降至第三设定值，则该节车内的压力调节器启动重联列车所有空压机，当该节车的总风压力达到目标值时，该节车内的压力调节器关闭重联列车所有空压机。The air compressor start-stop control system of the heavy-duty train in this embodiment also includes a pressure regulator installed in each car of the heavy-duty train. When the heavy-duty train enters the emergency traction mode, if the total air pressure of a certain car of the heavy-duty train drops to the third set value, the pressure regulator in the car starts all the air compressors of the heavy-duty train. When the total air pressure of the train reaches the target value, the pressure regulator in the train turns off all air compressors of the heavy train.
本实施例中，空压机控制电路见图2。当重联列车网络正常时，TCMS控制空压机工作。来自车辆的供电电压经TCMS输出到空压机继电器＝35-K202，空压机继电器＝35-K202线圈得电后，空压机继电器的触点3-11闭合，空压机无故障时，接触器＝35-K201线圈得电，接触器＝35-K201的触点1-2、3-4、5-6闭合，空压机电机得电(当车辆AC380V供电正常时，空开35-F201处于闭合状态)，空压机启动，开始打风。In this embodiment, the air compressor control circuit is shown in Figure 2. When the heavy-duty train network is normal, TCMS controls the operation of the air compressor. The power supply voltage from the vehicle is output to the air compressor relay = 35-K202 through the TCMS. After the air compressor relay = 35-K202 coil is energized, the contact 3-11 of the air compressor relay is closed. When the air compressor has no fault, Contactor = 35-K201 coil is energized, contactor = 35-K201 contacts 1-2, 3-4, 5-6 are closed, and the air compressor motor is energized (when the vehicle AC380V power supply is normal, the air switch 35- F201 is in the closed state), the air compressor starts and starts to blow.
空压机继电器＝35-K202线圈得电后，空压机继电器＝35-K202的触点4-12亦闭合，空压机内部干燥器得电，干燥器与空压机开始同步工作。After the air compressor relay = 35-K202 coil is energized, the contacts 4-12 of the air compressor relay = 35-K202 are also closed, the dryer inside the air compressor is energized, and the dryer and the air compressor start to work synchronously.
当网络故障时，压力调节器控制空压机工作。当压力调节器检测到风压低于7.5bar(750kPa)时，压力调节器控制回路连通，空压机继电器＝35-K202线圈得电，控制空压机及干燥器工作。图2中的二极管35-V201用来防止本车或其他车的TCMS控制回路或压力调节器回路的电流反串。When the network fails, the pressure regulator controls the operation of the air compressor. When the pressure regulator detects that the wind pressure is lower than 7.5bar (750kPa), the pressure regulator control loop is connected, and the air compressor relay = 35-K202 coil is energized to control the operation of the air compressor and dryer. The diode 35-V201 in Figure 2 is used to prevent current reverse flow in the TCMS control loop or pressure regulator loop of this vehicle or other vehicles.
本实施例中，重联列车每节车内设置有两个压力调节器。每节中2个压力调节器互为备份，当其中一个压力调节器故障时，另一个压力调节器仍然可以控制本节车空压机的启停。本实施例的压力调节器工作范围为750kPa～1000kPa。In this embodiment, two pressure regulators are provided in each car of the heavy-duty train. The two pressure regulators in each section serve as backups for each other. When one of the pressure regulators fails, the other pressure regulator can still control the start and stop of the air compressor of this section. The working range of the pressure regulator in this embodiment is 750kPa～1000kPa.
同上述实施例1，重联列车每节车内的干燥器与对应车内的空压机同步工作。Similar to the above-mentioned Embodiment 1, the dryer in each car of the heavy-duty train works synchronously with the air compressor in the corresponding car.
本实施例中，处理单元可以为重联列车控制***(TCMS***)。在重联列车网络正常情况下，由TCMS***控制重联列车空压机的启停。在重联列车网络故障情况下，重联列车进入紧急牵引模式后，由压力调节器控制重联列车空压机的启停。In this embodiment, the processing unit may be a train control system (TCMS). Under normal conditions on the heavy-duty train network, the TCMS system controls the start and stop of the air compressor of the heavy-duty train. In the event of a heavy-duty train network failure, after the heavy-duty train enters the emergency traction mode, the pressure regulator controls the start and stop of the air compressor of the heavy-duty train.
