Description

Technical Field

[0001] The present invention belongs to the field of vehicle depots, and more specifically, relates to an intelligent lighting system for a vehicle depot operating platform. Background Art

[0002] In recent years, urban rail transit has developed rapidly, with a planned construction mileage of about 7,700 kilometers, of which more than 6,000 kilometers are under construction. The depot is a place for parking, maintenance and overhaul of subway vehicles, and the lighting system is the main power-consuming facility in the depot. Due to the large area of ​​the overhaul warehouse in the depot, the dense lighting facilities and the huge power consumption, if there is a lack of control and management, it will cause extreme waste of power resources.

[0003] In order to facilitate maintenance personnel to work on the side and roof of the vehicle, working platforms are usually set up on the side of the maintenance track of the monthly inspection depot, static adjustment depot, purge depot, and scheduled maintenance depot. The working platform is generally long. For example, the single-side working platform required for a 6-car subway vehicle is as long as 120m. The first floor elevation of the working platform is the ground, the second floor elevation is the height of the train floor, and the roof working platform elevation is the height of the train roof. Lighting fixtures are installed under the first and second floor working platforms, and the roof working platform relies on the lighting fixtures in the warehouse. A ladder is set at the end of the working platform for maintenance personnel to go up and down. For work safety, an access control system is set at the connection between the ladder and the platform.

[0004] At present, the lighting control of the working platform is generally controlled by switches. When the operator enters the working platform area to work, he turns on the switch and all the lamps under the platform are lit. After the work is completed, the switch is turned off. The problem with the current working mode is that the lamps are also turned on in areas where no one is working, which results in a waste of lighting and is not environmentally friendly and energy-saving. For example, the length of the single-row working platform of a 6-car train in a subway is 120m, and about 60 lamps are arranged on each working platform. However, the working range of the staff is very limited. If the lights outside the working range are always on, it will lead to a huge waste of electricity, making the daily operating cost of the lighting equipment high. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides an intelligent lighting system for a vehicle depot working platform, which can realize intelligent control and management of the working platform lighting equipment and reduce the daily operating costs of the lighting equipment.

[0006] To achieve the above object, the present invention provides an intelligent lighting system for a vehicle depot work platform, characterized in that it includes a work platform, a track, an intelligent lighting group, a lighting control panel and a vehicle sensor, wherein:

[0007] The working platform is arranged side by side with the track so that personnel can inspect and repair the train parked on the track on the working platform;

[0008] A plurality of the intelligent lighting groups are arranged on the working platform, each of the intelligent lighting groups comprises a human body sensor and a lighting fixture, wherein the human body sensor and the lighting fixture are respectively connected to the lighting control panel via a transmission cable, the human body sensor is used to detect whether a person enters the working platform and transmit the detection signal to the lighting control panel, and the human body sensor of each intelligent lighting group controls the lighting fixtures of the same intelligent lighting group to be turned on via the lighting control panel;

[0009] The vehicle sensor is arranged at the end of the working platform, and is used to detect whether a train enters the track and send a detection signal to the lighting control panel;

[0010] The lighting control panel controls the lighting states of all lighting fixtures based on the received signals from the human body sensor and the vehicle sensor.

[0011] Preferably, when neither the human body sensor nor the vehicle sensor sends a detection signal to the lighting control panel, the lighting control panel displays "no person, no vehicle", and at this time the lighting control panel controls all lighting fixtures to be turned off.

[0012] Preferably, when the human body sensor does not send a detection signal to the lighting control panel but the vehicle sensor sends a detection signal to the lighting control panel, the lighting control panel displays "No one has a car". At this time, the lighting control panel controls all lighting fixtures to turn on low light and turn off after a set delay time.

[0013] Preferably, when the human body sensor sends a detection signal to the lighting control panel and the vehicle sensor does not send a detection signal to the lighting control panel, "There is someone but no car" is displayed on the lighting control panel. At this time, the human body sensor that can detect the human body signal controls the lighting fixture corresponding to the human body sensor to turn on the strong light through the lighting control panel, and the lighting control panel controls other lighting fixtures to turn on the weak light.

[0014] Preferably, when the human body sensor sends a detection signal to the lighting control panel and the vehicle sensor also sends a detection signal to the lighting control panel, "There is someone and a car" is displayed on the lighting control panel. At this time, the human body sensor that can detect the human body signal controls the lighting fixture corresponding to the human body sensor to turn on the strong light through the lighting control panel, and the lighting control panel controls other lighting fixtures to turn on the weak light.

[0015] Preferably, the lighting controller controls a corresponding number of lighting fixtures to be turned on with strong light based on feedback information from a human body sensor that detects a person, and controls the remaining lighting fixtures to be turned on with weak light.

[0016] Preferably, the lighting fixture is an incandescent lamp or an LED lamp.

[0017] Preferably, the working platform is provided with multiple layers, and each layer is provided with multiple groups of the intelligent lighting groups.

[0018] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0019] 1) The present invention combines sensor recognition technology and intelligent control lighting equipment.

[0022] Figure 1 It is a front view of the present invention;

[0023] Figure 2 It is a schematic diagram of the application of the present invention. DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 , Figure 2 As shown, an intelligent lighting system for a vehicle depot working platform includes a working platform, a track, an intelligent lighting group, a lighting control panel 4 and a vehicle sensor 5, wherein:

[0026] The working platform is arranged side by side with the track so that personnel can perform maintenance on the train parked on the track on the working platform; preferably, the working platform is provided with multiple layers, and each layer is provided with multiple groups of the intelligent lighting groups.

[0027] A plurality of intelligent lighting groups are arranged on the working platform, each of which includes a human body sensor 2 and a lighting fixture 1. Preferably, the human body sensor 2 is a microwave sensor, wherein the human body sensor 2 and the lighting fixture 1 are respectively connected to the lighting control panel 4 via a transmission cable 3 to form an association. The intelligent lighting group can be arranged on the top of each floor of the working platform, and the human body sensor 2 is used to detect whether a person enters the working platform and transmit the detection signal to the lighting control panel 4, and the human body sensor 2 of each intelligent lighting group controls the lighting fixture 1 of the same intelligent lighting group to be turned on via the lighting control panel 4.

[0028] The vehicle sensor 5 is arranged at the end of the working platform, and is used to detect whether a train enters the track and send a detection signal to the lighting control panel 4; preferably, the vehicle sensor 5 is an infrared sensor.

[0029] The lighting control panel 4 controls the lighting status of all lighting fixtures 1 based on the received signals from the human sensor 2 and the vehicle sensor 5. At the maintenance position, the lighting system makes lighting strategy control based on the single track sensing, so that the lighting of each layer of the working platform does not interfere with each other; the human sensor 2 and the vehicle sensor 5 detect the status of personnel and trains, and feed back to the lighting control panel 4 to control the opening (weak light opening and strong light opening) and closing of the lighting fixtures 1 in the maintenance platform area. The change of light will change accordingly with the change of the working status of the train and personnel.

[0030] Furthermore, when neither the human sensor 2 nor the vehicle sensor 5 sends a detection signal to the lighting control panel 4 , the lighting control panel 4 displays “no person, no vehicle”, and at this time the lighting control panel 4 controls all the lighting fixtures 1 to be turned off.

[0031] Furthermore, when the human body sensor 2 does not send a detection signal to the lighting control panel 4 and the vehicle sensor 5 sends a detection signal to the lighting control panel 4, the lighting control panel 4 displays "No one has a car". At this time, the lighting control panel 4 controls all the lighting fixtures 1 to turn on in low light and turn them off after a set delay time, such as 10 minutes.

[0032] Furthermore, when the human body sensor 2 sends a detection signal to the lighting control panel 4 and the vehicle sensor 5 does not send a detection signal to the lighting control panel 4, the lighting control panel 4 displays "There is someone but no car". At this time, the human body sensor 2 that can detect the human body signal controls the lighting fixture 1 corresponding to the human body sensor 2 to turn on the strong light through the lighting control panel 4, and the lighting control panel 4 controls other lighting fixtures 1 to turn on the weak light.

[0033] Furthermore, when the human body sensor 2 sends a detection signal to the lighting control panel 4 and the vehicle sensor 5 also sends a detection signal to the lighting control panel 4, "There is someone and a car" is displayed on the lighting control panel 4. At this time, the human body sensor 2 that can detect the personnel signal controls the lighting fixture 1 corresponding to the human body sensor 2 to turn on the strong light through the lighting control panel 4, and the lighting control panel 4 controls other lighting fixtures 1 to turn on the weak light.

[0034] The lighting control panel 4 of the present invention divides the lighting conditions of the vehicle section into the above-mentioned four working conditions based on the detection signals of the human body sensor 2 and the vehicle sensor 5, and controls the closing, low-light turning on and high-light turning on of the lighting fixture 1 through the above-mentioned four working conditions. It can also control only the lighting fixture 1 closest to the personnel to turn on the high-light, thereby meeting the needs of intelligent control and management of the lighting fixture 1 and contributing to energy conservation and emission reduction.

[0035] Furthermore, the lighting control panel 4 controls a corresponding number of lighting fixtures 1 (e.g., four lighting fixtures 1 at the front and back, determined according to the illumination range of the lighting fixtures 1) to turn on strong light based on the feedback information of the human body sensor 2 that detects the person, and the remaining lighting fixtures 1 to turn on weak light. When the person moves, the strong light range also moves accordingly (i.e., the weak light of some lighting fixtures 1 will become strong light, and the strong light of some will become weak light). If the working platform has only one layer, the M lighting fixtures 1 closest to the top of this layer will turn on strong light. If the working platform has multiple layers, the lighting fixtures 1 closest to the person among all the lighting fixtures 1 will turn on strong light.

[0036] The weak light of the above-mentioned lighting fixture 1 is relative to the strong light. The illumination when the weak light is turned on is less than the illumination when the strong light is turned on. If there is no personnel in the vehicle depot, the above-mentioned weak light lighting fixture 1 can be completely turned off after the delay setting time. If there are personnel in the vehicle depot, the weak light will be kept on all the time.

[0037] Furthermore, in the intelligent lighting system, since the lighting fixture 1 is frequently turned on and off and changes in brightness (strong and weak light), the electric shock received by the lighting fixture 1 when it is started will have a significant impact on the life of the lighting fixture 1. Therefore, the lighting fixture 1 should preferably use incandescent lamps or LED lamps, and should not use fluorescent lamps and energy-saving lamps.

[0038] In the workshop section, the intelligent lighting system makes a control strategy based on the first layer of the work platform, and the lighting of each layer of the work platform does not interfere with each other. The human sensor 2 and the vehicle sensor 5 detect the status of the staff and the train, and then feed back to the lighting control panel 4 to control the lighting fixtures 1 in the work platform area. The changes in the lighting will change accordingly with the changes in the working status of the train and the personnel.

[0039] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
