Description

Technical Field

[0001] The invention relates to the technical field of train emergency lighting, and in particular to a train emergency lighting delay control method and system. Background Art

[0002] The vehicle emergency lighting of this project does not have a delayed disconnection function. When the vehicle is disconnected from the battery and the train is retracted, the vehicle emergency lighting will be disconnected immediately. At the same time, the emergency lighting of this project is powered by a non-permanent busbar. After the train battery is disconnected, the emergency lighting has no power supply. The diameter of the permanent busbar of the train that runs through the entire vehicle is 1.5mm2, which cannot provide sufficient power to supply the emergency lighting load. There is insufficient space inside the wire tube under the train, and it is impossible to re-lay the train through wires of 6mm2 and above. The vehicle-end coupling connector does not have pin points for wire diameters of 6mm2 and above. If the train coupling connector is to be rebuilt, the existing vehicle coupling connector and cables need to be removed and returned to the factory for modification. The time period is too long to meet the needs of train online operation and the cost is huge.

[0003] In order to meet the delayed disconnection function of vehicle emergency lighting, a new train emergency lighting delay control method is proposed to solve this problem. This control method can realize the train emergency lighting delay function by laying a 6mm2 diameter cable in the head car. At the same time, there are 6 emergency power supply buses. Any fault in one bus will affect the emergency lighting of at most one car, and will not affect the emergency lighting of other cars. It ensures that the emergency lighting function in the car will not be lost in extreme cases, and will not cause panic among passengers, thus maximizing the safety performance of the train, and the solution is easy to implement.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Example 1, reference Figure 1 to Figure 15 , which is the first embodiment of the present invention, and provides a train emergency lighting delay control method, including: powering the emergency lighting main circuit, using battery power to power the emergency lighting control circuit; setting up the whole car emergency lighting control circuit to achieve control of emergency lighting and normal lighting; and performing train emergency lighting delay control.

[0038] First, lead out a 6mm 2 Permanent power supply bus, 6 1.5mm high voltage busbars are connected to the low voltage box at the second end of the train through a one-to-six terminal block 2 The cable runs through the entire car to provide power for the train's emergency lighting fixtures. When the train key is activated, the SD normally open contact in the figure is closed, and the train activation self-reset knob is pressed. Through the anti-reverse current diode VD3, the QC1 contactor and the KC1 undervoltage relay can be connected, and the QC1 contactor excitation is self-locked under the condition of KC1 excitation; after the QC1 normally open contact is closed, the emergency lighting delay relay of the lead car with a driver's cab at both ends is connected, so that the emergency lighting control contactor 52-K06 of the entire car is excited, and then the emergency lighting power supply circuit is closed through the 52-K06 normally open contact. The lighting control switch is set on the lead car with a driver's cab. After operating the switch, the ordinary lighting and the train emergency lighting are controlled to light up. After the high voltage and battery of the train are disconnected, the emergency lighting delay relay 52-K05 delays the disconnection of the emergency lighting main circuit. By setting a certain delay time for the delay relay, the train emergency lighting is finally disconnected with a delay. For details of the overall control circuit, please see the attached Figure 2 and Figure 3 .

[0039] S1. Power the emergency lighting main circuit and use battery power to power the emergency lighting control circuit.

[0040] Emergency lighting main circuit power supply. The rear end of the QF28 circuit breaker in the battery box leads to the 3306 line, which passes through the 32A circuit breaker QF30 and leads to the permanent power supply bus 3319 line, with a wire diameter of 6mm 2 , see Figure 4 .

[0041] 3319 line enters the low voltage box, and leads out 6 2.5mm 2Line, through the anti-reverse current diodes VD6, VD7, VD8, VD9, VD10 and VD11, it is divided into 6 paths (33191, 33192, 33193, 33194, 33195, 33196) 1.5mm 2 The line runs through cars 2, 3, 4 and 5. Figure 5 and Figure 6 shown.

[0042] 33191, 33192, 33193, 33194, 33195 and 33196 supply power to the emergency lighting loads of the six cars respectively. Taking TC1 car as an example, 33191 supplies power to the emergency lighting EL5, EL11, EL13, EL19 and the through-channel lights ELG1 and ELG2 through the circuit breaker 5QF13, 52-K06 contactor and 5KM11 contactor. The other cars are similar, such as Figure 7 shown.

[0043] Emergency lighting control circuit power supply, the train battery box circuit breakers QF28, QF29 are normally in the closed state, the battery power passes through the VD1 and VD2 diodes, to the 3301 line power supply, 3301 is the emergency lighting control cable throughout the train. Figure 8 shown.

[0044] S2. The whole vehicle emergency lighting control circuit is set up to realize the control of emergency lighting and normal lighting.

[0045] The vehicle lighting control circuit is used to control emergency lighting and normal lighting, which is achieved by controlling contactors 5KM11 and 5KM12. 5KM11 is used to control the main circuit of emergency lighting and one circuit of normal lighting, and 5KM12 is used to control the two circuits of normal lighting.

[0046] When the lighting control switch is operated, the 52K04 lighting holding relay is turned on and self-locked through the 3301 power supply line, and the contactors 5KM11 and 5KM12 are energized through 33191 (33196 for car 6) and 3301 line. Fig. 9 shown.

[0047] S3. Perform delay control of train emergency lighting.

[0048] The emergency lighting control circuit of each carriage is similar, taking TC1 car as an example.

[0049] The emergency lighting control circuit is powered separately from the emergency lighting load power supply circuit. It draws power from the permanent power supply bus 3301 line, passes through 52232 to the power supply end of the power-off delay relay 52-K05 / 1, and passes through the unidirectional diode 52-V03 to the normally open contact of the battery DC contactor QC1, and the BATR normally closed contact enters the 52-K05 / 5 control end. When the battery of a normal train is powered on, QC1 is closed, the driver's console lighting control knob is turned to the closed position, the 52-K06 normally open contact is closed, the 5KM11 normally open contact is closed, and the train emergency lighting is on. Press the battery disconnect button, the 52-K05 relay delay function is triggered, the 52-K05 relay delays for 5 minutes and the state flips. After 5 minutes, the 52-K06 normally open contact is reset from closed to normally open, the emergency lighting load power supply line is disconnected, and the passenger compartment emergency lighting is extinguished after a delay of 5 minutes. When the driver's console lighting control knob is in the off position, the 5KM11 normally open contact cuts off the main circuit of the emergency lighting load, and the emergency lighting goes out without delay. Fig.10 .

[0050] The QC1 contactor in the battery box is modified. Since the auxiliary contacts of QC1 in this project are two normally open and two normally closed contacts, two sets of normally open contacts have been used. The emergency lighting control circuit still needs to use a set of normally closed contacts. Since the existing QC1 contactor cannot directly convert the normally closed contacts into normally open contacts, it is necessary to modify the DC contactor QC1. The two normally open and two normally closed auxiliary contacts of the DC contactor QC1 in the battery box are modified to four normally open auxiliary contacts at the bottom. The detailed structure after the modification is as follows Fig.11 As shown in the red box.

[0051] Emergency lighting control electrical components installation, emergency lighting electrical components see Fig.12 , installed on the left bracket, see Fig.13 The left bracket is installed on the cabinet. Fig.14 shown.

[0052] Install the power distributor and diode. Install the guide rail in the low-voltage box of the TC1 car, and install the power distributor and diode on the guide rail. Fig.15 shown.

[0053] Example 2, reference Fig.16 , which is the second embodiment of the present invention, is different from the previous embodiment in that it provides a train emergency lighting delay control system, including: a power supply module 100, a lighting control module 200 and a delay control module 300.

[0054] The power supply module 100 is used to supply power to the emergency lighting main circuit and utilizes battery power to supply power to the emergency lighting control circuit.

[0055] The lighting control module 200 is used for the emergency lighting control circuit setting of the whole vehicle to realize the control of emergency lighting and normal lighting.

[0056] The delay control module 300 is used to perform delay control of train emergency lighting.
