Description

Technical Field

[0001] The present invention relates to the technical field of rail transit lighting control, and in particular to a rail transit tunnel lighting control processing system and method. Background Art

[0002] The existing rail transit tunnel lighting has the following disadvantages: 1. Safety hazards. At present, the illumination of lamps in the tunnel is basically consistent without gradual changes. The illumination changes dramatically at the tunnel entrance and at the entrance and exit of the station. In this case, the driver's pupil may experience "black hole effect" and "white hole effect", causing visual and mental fatigue, and even temporary blindness, which poses a serious safety risk. 2. Low reliability. At present, rail transit tunnel lighting is designed to be turned on 24 hours a day. Traditional LED lighting driver power supplies have poor reliability, short life, cannot be started and stopped frequently, and do not have equipment fault tolerance. The subsequent maintenance cost investment is large. 3. Low flexibility. At present, the illumination intensity of rail transit tunnel lighting equipment is fixed and cannot be automatically adjusted according to the operation scenario. The excessive illumination intensity in the no-car scenario is invalid lighting, but the lighting in the maintenance and fault repair scenario is seriously insufficient. 4. Low energy utilization. At present, the reactive power compensation efficiency of the rail transit power supply system is low, the energy utilization rate is not high, and the energy waste is huge. Summary of the invention

[0039] Specifically, Figure 1 As shown, in this embodiment, the central processing module is used for central processing of data; the tunnel lighting module is electrically connected to the central processing module; the receiving module is electrically connected to the central processing module, the logic module is electrically connected to the central processing module; and the display module is electrically connected to the central processing module. The tunnel lighting module is used for lighting inside the tunnel, the receiving module is used to receive data and transmit the data to the central processing module, and the data is processed by the central processing module to adjust and control the lighting intensity of the tunnel lighting module. The logic module is used to configure the lighting adjustment strategy and monitor the operation of the lighting equipment. The lighting situation of the entire line can be displayed intuitively on the large screen of the control center through the large screen access device. The central processing module adjusts and controls the lighting intensity through the strategy adjusted by the logic module, and the display module is used to realize human-computer interaction, and is also used to project the execution results of the lighting control information to the display screen and / or the large screen.

[0040] Further, if Figure 1 As shown, in this embodiment, the central processing module includes: a central processing unit, the central processing unit is electrically connected to the tunnel lighting module, the receiving module and the display module respectively, and the central processing unit is used to electrically connect to the tunnel lighting module, the receiving module and the display module to process instructions, execute operations, control time and process data.

[0041] Further, if Figure 1 As shown, in this embodiment, the central processing unit communicates with an external control terminal, and the central processing unit can be controlled by the external control terminal to adjust the lighting intensity of the tunnel lighting module.

[0042] Further, if Figure 1~2As shown, the tunnel lighting module includes: a dimming actuator, a passive driving power supply and a lamp. In this embodiment, the dimming actuator is electrically connected to the central processing module; the passive driving power supply is electrically connected to the dimming actuator; the lamp is electrically connected to the passive driving power supply; the monitor is electrically connected to the dimming actuator, which is used to detect the working conditions of the passive driving power supply and the lamp, and plays the role of "fault-guided safety".

Dimming actuators are equipped to achieve a 10-level illumination adjustment function, which has the following advantages: 1. High safety. The new passive driving power supply has high reliability and strong equipment fault tolerance. Replacing the traditional driving power supply can greatly reduce the failure rate of lighting equipment in the tunnel. The multi-level dimming system can adjust the LED light intensity according to the installation position of the lamp, eliminate the drastic changes in the light in the tunnel, enable the driver's eyes to gradually adapt to the light changes, effectively relieve the driver's fatigue, and completely avoid safety accidents caused by temporary blindness. 2. Improve the efficiency of power utilization. At the same time, the reactive power compensation function of the passive drive power supply can improve the efficiency of operating lighting power utilization, reduce the reactive power of the power supply system, significantly reduce the operating power cost, and enable enterprises to achieve the national strategic goals of carbon peak and carbon neutrality as soon as possible. 3. Convenient transformation. The replacement of the passive drive power supply is very simple. It only requires replacing the original drive power supply. There is no need to replace the lamps or re-lay the cables. 4. Easy to expand. The multi-level dimming system can be designed with reserved control capacity, which can be easily expanded when the new line lighting system is connected and the station lighting system is connected. The control range of the intelligent lighting system can be customized according to design requirements.

[0043] Lighting control method

[0044] The dimming actuator installed on site adopts capacitive dimming method. The I / O conversion module communicates with the host computer, receives the dimming signal, converts it into a hard contact signal and drives the corresponding contactor. The contactor selects the number and number of capacitors connected to the circuit to achieve the change of the capacitance of the entire lighting circuit, thereby changing the current of each passive drive power supply in the circuit to achieve dimming control.

[0045] Further, if Figure 1~2As shown, in this embodiment, the receiving module includes: an interface server, one end of the interface server is electrically connected to the central processing module, and the other end communicates with the external train automatic monitoring system and the external rail transit integrated monitoring system. The data signal received by the interface server includes real-time operation status information and tunnel civil engineering information; the real-time operation status information includes but is not limited to the train number, train car number, train position, train speed, train mode, train destination and section fault; the tunnel civil engineering information includes but is not limited to the tunnel and station and / or ground connection information, tunnel slope and tunnel curvature, and the interface server communicates with the external train automatic monitoring system (ATS system) and the external rail transit integrated monitoring system (ISCS system) to realize information collection and collection, so that according to different signal data, the tunnel lighting control algorithm model based on train positioning is called to intelligently control the lighting intensity in the tunnel, and realize the tidal tunnel lighting intelligent control strategy of "lights on when the car comes and dark when the car leaves". Automatically adjust the lighting intensity according to different operation scenarios, provide sufficient lighting in scenes where lighting is required, reduce the lighting intensity in scenes where lighting is not required, and greatly reduce the power consumption of operation lighting.

[0046] Further, if Figure 1 As shown, in this embodiment, the display module includes: a display screen, the display screen is electrically connected to the central processing module, the display screen is used to realize human-computer interaction, and is also used to clearly display the execution result of the lighting control information.

[0047] Further, if Figure 1~2 As shown, in this embodiment, the logic module includes: an application server, the application server is electrically connected to the central processing unit, the application server is used to calculate the lighting control software, configure the lighting adjustment strategy and monitor the operation of the lighting equipment, and the lighting conditions of the entire line can be projected onto the large screen of the control center through the large-screen access device for intuitive display.

[0048] In order to adapt to the operation scenarios under special circumstances, the dimming execution part adopts a multi-level logic judgment function to judge the operation scenarios according to the different operation states of the external train automatic monitoring system and the external rail transit comprehensive monitoring system, such as Figure 2 As shown, when an abnormality occurs in some sections or some trains, the dimming system of the corresponding section immediately switches to bypass mode, and the dimming actuator automatically turns on the maximum illumination mode to ensure the lighting needs of emergency rescue.

[0049] For normal operation scenarios, the tunnel lighting system has three different operating modes: fully automatic mode, manual mode, and non-adjustable mode. When equipment fails, it can automatically switch between modes. The central processing module communicates with the external integrated backup disk (station IBP disk) and the external station control terminal, controls the software interface of the external integrated backup disk or the external station control terminal, and can set the operating mode of the entire line or part of the section.

[0050] Lighting control logic

[0051] The train position, train speed, train driving mode, train detention and train skipping mode information are retrieved from the signal system.

[0052] The mathematical model formula of train speed-lighting distance is established according to the driver's driving reaction time:

[0053]

[0054]

[0055] Among them, coefficient A is the lighting distance when the train speed is 0; V is the actual running speed of the train; K is the curve power variable; To account for tunnel environmental variables, the lighting distance is increased at civil engineering slopes and curves; It is an event variable. When the train is detained, the section is blocked or other unexpected situations occur, all lights will be automatically turned on to ensure emergency rescue.

[0056] Above, refer to Figure 1~2 The rail transit tunnel lighting control processing system and method according to the embodiment of the present invention are described, which have high safety. The passive LED driver power supply not only realizes the functions of AC / DC conversion and voltage stabilization, but also provides fault tolerance function to improve the safety and reliability of the equipment.

Good scalability, the multi-level dimming system itself has high flexibility, and the control capacity can be freely adjusted according to user needs. When the new line lighting system and the station lighting system are connected, the control range of the intelligent lighting system can be easily extended. The implementation cycle is short, and intelligent lighting control can be realized by replacing the passive LED driver power supply and installing control equipment. There is no need to replace the original LED lamps and there is no need to re-lay the cables in the tunnel.
