Description

Technical Field

[0001] The present invention belongs to the field of vehicle depots, and more specifically, relates to an intelligent lighting system for inspection ditches in vehicle depots. Background Art

[0002] In recent years, urban rail transit has developed rapidly. The planned construction mileage of urban rail is about 7,700 kilometers, of which the under-construction mileage exceeds 6,000 kilometers. A vehicle depot is a place for parking, maintaining, and inspecting subway vehicles. In order to facilitate the inspection of the equipment under the vehicle, inspection ditches are generally set on the main inspection tracks in the vehicle depot. When the train is parked, personnel enter the ditch for operation. Therefore, lighting facilities need to be considered in the ditch.

[0003] Currently, the lighting of inspection ditches in urban rail transit vehicle depots mainly sets wall lamps on the side walls of the inspection ditches. Before entering the ditch, maintenance personnel manually turn on the lighting switch as needed to turn on the lighting lamps in the entire inspection ditch. The number of inspection ditches in the vehicle depot is huge. The length of a single inspection ditch is up to 140 m. Generally, the total length of the inspection ditches in the vehicle depot is greater than 5,000 m. The lighting lamps in the ditch are generally arranged at a distance of 1.5 m, and the power of each lamp is greater than 50 W. Therefore, the lighting facilities in the inspection ditch are dense and the power consumption is extremely high. If there is a lack of control and management, it will cause extremely wasteful use of electric power resources. In addition, the working range of personnel is very limited, and the lights in the non-working range being constantly on will also lead to extremely wasteful use of electric energy, resulting in a relatively high daily operating cost of the lighting equipment. Summary of the Invention

[0004] In view of the above defects or improvement requirements of the prior art, the present invention provides an intelligent lighting system for inspection ditches in vehicle depots, which realizes the intelligent control and management of the lighting equipment in the inspection ditches and reduces the daily operating cost of the lighting equipment.

[0005] To achieve the above object, the present invention provides an intelligent lighting system for inspection ditches in vehicle depots, including a plurality of inspection bays. Each inspection bay includes an inspection ditch, a track, a column, an intelligent lighting group, a lighting controller, and a vehicle sensor, wherein:

[0006] The track is located directly above the inspection ditch and is supported by two rows of the columns. Each column is vertically arranged on the foundation beside the inspection ditch;

[0007] There are multiple groups of the intelligent lighting groups. Each group of the intelligent lighting groups includes a human body sensor and a lighting fixture. Among them, the human body sensor and the lighting fixture are respectively connected to the lighting controller through a transmission cable. The human body sensor is used to detect whether there are people entering the maintenance trench and send the detection signal to the lighting controller. And the human body sensor of each group of the intelligent lighting groups controls the lighting fixture of the same group of the intelligent lighting groups to turn on through the lighting controller. In addition, the height of the lighting fixture does not exceed the height of the column.

[0008] For each row of the columns, one group of the intelligent lighting groups is set at every set number of columns.

[0009] The vehicle sensor is arranged at the vehicle-in end of the track to detect whether there is a train on the track and send the detection signal to the lighting controller.

[0010] The lighting controller controls the lighting state of the lighting fixture based on the signals received 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 controller, the lighting controller displays "no people, no train", and at this time the lighting controller controls all the lighting fixtures to turn off.

[0012] Preferably, when the human body sensor does not send a detection signal to the lighting controller while the vehicle sensor sends a detection signal to the lighting controller, the lighting controller displays "no people, there is a train", and at this time the lighting controller controls all the lighting fixtures to turn on with low light and turn off after a set time delay.

[0013] Preferably, when the human body sensor sends a detection signal to the lighting controller while the vehicle sensor does not send a detection signal to the lighting controller, the lighting controller displays "there are people, no train", and at this time the human body sensor that can detect the personnel signal controls the lighting fixture corresponding to the human body sensor to turn on with strong light through the lighting controller, and the lighting controller controls the other lighting fixtures to turn on with low light.

[0014] Preferably, when the human body sensor sends a detection signal to the lighting controller and the vehicle sensor also sends a detection signal to the lighting controller, the lighting controller displays "there are people, there is a train", and at this time the human body sensor that can detect the personnel signal controls the lighting fixture corresponding to the human body sensor to turn on with strong light through the lighting controller, and the lighting controller controls the other lighting fixtures to turn on with low light.

[0015] Preferably, the lighting controller controls the corresponding number of lighting fixtures to turn on with strong light based on the feedback information of the human body sensor that detects people, and the remaining other lighting fixtures turn on with low light.

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

[0017] Preferably, the human body sensor is a microwave sensor.

[0018] Preferably, the vehicle sensor is a pressure sensor.

[0019] Generally speaking, compared with the prior art, the above technical solution conceived by the present invention can achieve the following beneficial effects:

[0020] 1) The present invention combines sensor recognition technology and intelligent control of lighting equipment. Through the human body sensors and vehicle sensors in the inspection bays, the lighting in the inspection trenches is controlled according to different states such as the presence of people and vehicles, so as to ensure the lighting in the working area and reduce unnecessary lighting in the non-working area.

[0021] 2) The present invention meets the requirements of intelligent control and management of lighting equipment, can effectively reduce the daily operation cost of the lighting equipment in the inspection trenches of the vehicle depot, and helps to save energy and reduce emissions.

[0022] 3) The present invention can realize the sectional and zonal control of the lighting in the inspection trenches. The lighting of each inspection bay is independent of each other, so as to achieve the purpose of non-interference between each track. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to 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 used 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.

[0027] As Figures 1 to 3 shown, an intelligent lighting system for inspection trenches in a vehicle depot includes a plurality of inspection bays. Each inspection bay includes an inspection trench 2, a track 5, a column 3, an intelligent lighting group, a lighting controller 7 and a vehicle sensor 8, wherein:

[0028] The track 5 is located directly above the maintenance trench 2 and is supported by two rows of the columns 3. Each column 3 is vertically arranged on the foundation beside the maintenance trench 2. After the train 9 enters the maintenance position, it stops on the track 5.

[0029] There are multiple groups of the intelligent lighting units. Each group of the intelligent lighting units includes a human body sensor 1 and a lighting fixture 4. Preferably, the human body sensor 1 is a microwave sensor. Among them, the human body sensor 1 and the lighting fixture 4 are respectively connected to the lighting controller 7 through a transmission cable 6 to form an association. The lighting fixture 4 can be arranged on the foundation beside the maintenance trench 2, and the human body sensor 1 can be arranged on the vertical rod supporting the lighting fixture 4. The human body sensor 1 is used to detect whether there are people entering the maintenance trench 2 and send the detection signal to the lighting controller 7. And the human body sensor 1 of each group of the intelligent lighting units controls the turning on of the lighting fixture 4 of the same group of the intelligent lighting units through the lighting controller 7. In addition, the height of the lighting fixture 4 does not exceed the height of the column 3, so that it can irradiate the equipment at the bottom of the train 9, facilitating the maintenance of the bottom of the train 9.

[0030] For each row of the columns 3, one group of the intelligent lighting units is arranged at every set number of columns 3. The intelligent lighting units can be reasonably arranged according to the interval of the columns 3 and the illuminance of the lighting fixture 4 to ensure the illuminance requirements during maintenance.

[0031] The vehicle sensor 8 is arranged on the track 5 to detect whether there is a train 9 on the track 5 and send the detection signal to the lighting controller 7. Preferably, the vehicle sensor 8 is a pressure sensor. Multiple vehicle sensors 8 can be arranged and they are longitudinally arranged along the track 5, which helps to ensure the accuracy of detection.

[0032] The lighting controller 7 controls the lighting state of the lighting fixture 4 (the lighting state includes the weak light on state, the strong light on state and the off state) based on the signals received from the human body sensor 1 and the vehicle sensor 8. In the maintenance position, the lighting system makes lighting strategy control based on single-track induction, so that the lighting of the track 5 does not interfere with each other. The human body sensor 1 and the vehicle sensor 8 detect the states of people and the train 9 and feedback them to the lighting controller 7 to control the turning on (having two on states of weak light on and strong light on) and off of the lighting fixture 4 in the area of the maintenance trench 2. The change of the light will change correspondingly with the change of the states of the train 9 and the positions of people.

[0033] Furthermore, when neither the human body sensor 1 nor the vehicle sensor 8 sends a detection signal to the lighting controller 7, the lighting controller 7 displays "no people and no train", and at this time, the lighting controller 7 controls all the lighting fixtures 4 to be turned off.

[0034] Further, when the human body sensor 1 does not send a detection signal to the lighting controller 7 while the vehicle sensor 8 sends a detection signal to the lighting controller 7, the lighting controller 7 displays "no person but vehicle". At this time, the lighting controller 7 controls all the lighting fixtures 4 to turn on with low light, and turns them off after a set delay time, such as 10 minutes.

[0035] Further, when the human body sensor 1 sends a detection signal to the lighting controller 7 while the vehicle sensor 8 does not send a detection signal to the lighting controller 7, the lighting controller 7 displays "person but no vehicle". At this time, the human body sensor 1 that can detect the personnel signal controls the lighting fixture 4 corresponding to the human body sensor 1 to turn on with strong light through the lighting controller 7, and the lighting controller 7 controls the other lighting fixtures 4 to turn on with low light.

[0036] Further, when the human body sensor 1 sends a detection signal to the lighting controller 7 and the vehicle sensor 8 also sends a detection signal to the lighting controller 7, the lighting controller 7 displays "person and vehicle". At this time, the human body sensor 1 that can detect the personnel signal controls the lighting fixture 4 corresponding to the human body sensor 1 to turn on with strong light through the lighting controller 7, and the lighting controller 7 controls the other lighting fixtures 4 to turn on with low light.

[0037] Based on the detection signals of the human body sensor 1 and the vehicle sensor 8, the lighting controller 7 of the present invention divides the lighting conditions in the vehicle section into the above four working conditions of "no person and no vehicle", "no person but vehicle", "person but no vehicle", and "person and vehicle", and controls the turning off, low-light turning on, and strong-light turning on of the lighting fixtures 4 through the above four working conditions. Moreover, it can also control only the lighting fixture 4 closest to the person to turn on with strong light, so as to meet the needs of intelligent control and management of the lighting fixtures 4, and contribute to energy conservation and emission reduction.

[0038] Further, the lighting controller 7 controls a corresponding number (such as four lighting fixtures 4 in the front and four in the back, determined according to the irradiation range of the lighting fixtures 4) of lighting fixtures 4 to turn on with strong light based on the feedback information of the human body sensor 1 that detects the person, and the remaining other lighting fixtures 4 turn on with low light. As the person moves, the strong-light range (the combination of lighting fixtures 4 that turn on with strong light) will also move accordingly, that is, the low light of some lighting fixtures 4 will become strong light, and the strong light of some will become low light. The lighting fixtures 4 of the present invention are set in a regionalized manner, and each region is seamlessly connected. When walking from region A to region B, the lighting fixtures 4 in region B will light up, and the lighting fixtures 4 in region A will gradually go out.

[0039] The low-light turning on of the above lighting fixtures 4 is relative to the strong-light turning on. The illuminance of the low-light turning on is less than that of the strong-light turning on. If there is no person in the vehicle section, the above lighting fixtures 4 that turn on with low light can all be turned off after a set delay time, and if there is a person in the vehicle section, they will keep turning on with low light.

[0040] Furthermore, in the intelligent lighting system, since the lighting fixture 4 is frequently turned on and off and its brightness changes (strong and weak light changes), the lighting fixture 4 will be greatly affected by the current impact when it starts, which will have a greater impact on the lifespan of the lighting fixture 4. Therefore, incandescent lamps or LED lamps are preferably used for the lighting fixture 4, and fluorescent lamps and energy-saving tubes are not suitable.

[0041] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
