Description

Technical Field

[0001] The utility model relates to the field of passenger compartment lighting brightness testing, in particular to a subway train passenger compartment lighting brightness auxiliary testing device. Background Art

[0002] Since some subway lines not only run in underground tunnels but also on ground viaducts, in order to improve convenience, the passenger compartment lighting of subway trains is generally automatically controlled in brightness. Generally, the brightness of the passenger compartment lighting is adjusted according to the outdoor light intensity collected by the outdoor light sensor, so as to change the brightness of the lights in the car according to changes in the environment, thereby improving riding comfort and achieving the effect of energy conservation and emission reduction.

[0003] During the maintenance of subway trains, it is also necessary to test the lighting function. During the test, it is necessary to use a lamp with adjustable light intensity to illuminate the light sensor. However, since the light sensor of the train is generally set above the front of the train, the existing technology requires high-altitude operations to perform light tests on the light sensor, and judge whether the sensor function is intact based on the changes in the brightness of the lights in the passenger compartment. This maintenance method is not only time-consuming and labor-intensive, but also has certain safety risks. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] A subway train passenger compartment lighting brightness auxiliary test equipment, such as Figure 1 As shown, it includes a lighting fixture 1, a lighting fixture connector 2 and a telescopic rod 3 which are connected in sequence;

[0033] like Figure 2 As shown, the lamp connecting member 2 includes a connecting bar 21, a connecting shaft 23, and a rotating joint 22 connecting the connecting bar 21 and the connecting shaft 23.

[0034] The connecting bar 21 is arranged on the lighting fixture 1 , and the connecting shaft 23 is coaxially connected to the telescopic rod 3 .

[0035] Based on telescopic rods and lamp connectors, such as Figure 6 As shown, the distance between the operating position and the lighting fixture can be lengthened, so that the lighting fixture can be controlled at the ground position to illuminate the light sensor of the train, thereby improving the test efficiency and convenience.

[0036] In some embodiments, the rotating joint is a universal joint, so that the angle can be more flexible, so that the test can be performed standing at the side of the train. Compared with being located directly in front, since there is no influence of the protruding front of the train, the length of the telescopic rod can be shortened, the torque influence generated by the lighting fixture 1 is reduced, and the handling performance is improved.

[0037] Of course, in some other embodiments, other forms of rotary joints may also be used. For example, in some embodiments, Figure 4As shown, the rotating joint includes a first ear seat 221, a second ear seat 222 and a rotating shaft 223. The first ear seat 221 is arranged on the connecting strip 21, and the second ear seat 222 is arranged on the connecting shaft 23. The rotating shaft 223 passes through the first ear seat 221 and the second ear seat 222 in sequence, and adopts the form of a lamp connector of an ear seat and a rotating shaft, so that there is only one degree of rotational freedom, which reduces the difficulty of operation. Specifically, in some embodiments, the first ear seat and the second ear seat are arranged in parallel, and the second ear seat is located in the first ear seat, so that the space occupation can be reduced and the stability can be improved. In addition, in some embodiments, the second ear seat is arranged on the side of the connecting shaft 23, and the controllability is better. And the first ear seat is perpendicular to the connecting strip 21, which reduces the use of materials, reduces weight, and improves the control performance.

[0038] In addition, a controller is provided on the telescopic rod 3, and the controller is located at the first end of the telescopic rod 3. The second end of the telescopic rod 3 is connected to the lamp connector 2, and the controller is connected to the lighting fixture 1. In some embodiments, the controller can be connected to the lighting fixture 1 via a cable, but this method will cause the cable to curl due to the use of the telescopic rod, affecting the appearance and lifespan.

[0039] Therefore, in some embodiments, a wireless control method can be adopted. For example, in some embodiments, the lighting fixture 1 includes a shell, a translucent lampshade and a lamp body. The shell and the translucent lampshade are combined to form an inner cavity. The lamp body is located in the inner cavity. The lamp body includes a first power supply, an LED lamp and a wireless receiver. The controller includes a second power supply, a manual key switch and a wireless transmitter. The positive pole of the second power supply is connected to the positive pole of the power input terminal of the wireless transmitter through the manual key switch, and the negative pole of the second power supply is connected to the negative pole of the power input terminal of the wireless transmitter. The positive pole of the first power supply is connected to the positive pole of the power input section of the wireless receiver and the COM port of the wireless receiver. The negative pole of the first power supply is connected to the negative pole of the power input section of the wireless receiver and the negative pole of the LED lamp. The positive pole of the LED lamp is connected to the ON port of the wireless receiver. The wireless transmitter and the wireless receiver have the same frequency. When the wireless receiver receives the signal of the wireless transmitter, the COM port and the ON port are connected, otherwise the COM port and the ON port are disconnected. Therefore, the LED lamp can be powered on by pressing the manual key switch.

[0040] like Figure 3 As shown, the controller 6 is arranged on the telescopic rod 3 through the module sleeve 5 and the connecting screw sleeve 4, and is fixed on the outside through the button protection cover 7, so as to protect the controller 6.

[0041] The operation process of this application is as follows: adjust the angle of the lighting fixture 1 through the lighting fixture connector 2 so that it can be completely attached to the sensor above the front of the train, and appropriately adjust the length of the telescopic rod 3 so that the staff can operate the detection device even when standing on the ground. The staff controls the flickering of the lighting fixture 1 through the controller. When the lighting fixture 1 is on, observe whether the brightness of the light in the train passenger compartment dims or goes out within the specified time; when the lighting fixture 1 is off, observe whether the brightness of the light in the train passenger compartment turns on or brightens within the specified time. The changes in the passenger compartment light are used to determine whether the sensor function at the head of the train is intact.
