Description

Technical Field

[0001] The utility model relates to the technical field of advertising light boxes, in particular to a subway intelligent light box system. Background Art

[0002] With the development of economy and the progress of science and technology, subway advertising media has outstandingly highlighted its advantages in the entire outdoor advertising army. The continuous emergence of new media and the diversity of media forms, from the application of conventional media for guidance and unconventional media for coverage to the use of digital advertising systems, have played a huge role in the dissemination effect of advertising.

[0003] Metro lines in cities usually have a large and stable passenger volume. As part of consumers' daily lives, the subway provides advertisers with many opportunities to place advertisements. More and more space in subway stations is reserved for advertising, and the revenue generated by advertising is gradually increasing.

[0004] At present, the planning and construction of subways in first-tier cities have been basically completed, so the subway advertising industry is also mainly concentrated in first-tier cities. However, as second- and third-tier cities also begin to vigorously develop rail transit and airport lighting industries, subway advertising will inevitably generate new revenue and gain greater market potential.

[0005] Subway advertising light boxes have many advantages, but in the actual operation and maintenance process, the owner pointed out that the existing subway advertising light boxes lack modern information management technology. The main problems are:

[0006] a. Single control method, unable to dim and calculate power consumption;

[0007] Most of the existing subway light boxes use the distribution box to turn on / off on a scheduled basis, and cannot be dimmed and switched on individually, and the operating status of the light boxes cannot be obtained in real time.

[0008] b. Lack of effective monitoring and failure to eliminate faults in a timely manner

[0009] Existing subway light boxes often use manual inspection methods and lack effective automatic monitoring methods, such as short circuit alarms, high temperature alarms, illegal opening, etc., making it difficult to prevent them in a timely manner, and long-term operation cannot completely eliminate safety risks.

[0010] c. No efficient management platform and low level of intelligence

[0011] The existing subway light box equipment lacks a unified intelligent management system. The light boxes in each area need to be manually recorded, counted and reported on site, which not only wastes a lot of manpower and material resources, but also easily leads to management loopholes.

[0012] Based on this, a subway advertising light box capable of dimming and intelligent monitoring is needed. Utility Model Content

[0050] The subway intelligent light box system provided in this embodiment has the following advantages:

[0051] (1) Able to adjust the brightness and switch of a single light box to reduce the power consumption of the light box;

[0052] (2) By arranging a variety of different types of sensors, the light box can be self-checked and monitored for various abnormal operating conditions. When an abnormal operation occurs, an alarm will be sent to the host computer;

[0053] (3) Based on the ability to self-check abnormal conditions, this light box can reduce the intensity of personnel inspection and maintenance, optimize the operation and maintenance method of manual field recording, statistics and reporting in the existing technology, reduce operation and maintenance costs, and optimize management loopholes.

[0054] The working principle of this embodiment is as follows:

[0055] The intelligent gateway (5) is responsible for the communication and instruction transmission between the various sensors inside the light box (2), the dimming power supply (3) and the remote host. The intelligent gateway (5) has communication modes and interfaces such as 4G, 485 bus and TCP / IP. The remote host sends instructions to the intelligent gateway (5). The intelligent gateway (5) controls the dimming power supply (3) to switch on or off or adjust the working brightness according to the instructions. The dimming power supply (3) executes the switch instruction or outputs the corresponding working current to drive the LED light source group (4) to switch the light on or off or adjust it to a certain brightness.

[0056] The intelligent gateway (5) can collect the input and output voltage and current parameters of the power supply through the internal current detection unit (507), and when the power supply fails, it can issue a warning message in time;

[0057] The temperature sensor (9) collects the temperature inside the light box (2), and when the temperature exceeds the warning temperature of the light box, an early warning is issued;

[0058] The humidity sensor (11) collects the humidity in the light box (2). When the humidity is much higher than the average humidity of multiple adjacent light boxes, it is possible that water has entered the light box, and the light box will issue a humidity exceeding standard warning.

[0059] The smoke sensor (11) is responsible for smoke monitoring. If smoke is detected, it means that combustion may have occurred inside, and an early warning is issued, and the power output of the light box is cut off;

[0060] The tilt sensor (12) detects the position change of the light box. When the installation structure of the light box is unstable and the position of the light box changes greatly, a warning signal is automatically issued after exceeding the warning value.

[0061] The camera (6) is responsible for detecting the flow of people, and the remote host intelligently adjusts the working brightness of the light box according to the flow of people data from the camera (6) to achieve the best energy-saving effect;

[0062] The light box opening and closing sensor (14) can be a magnetic induction switch or a travel switch. When the light box is not closed or accidentally opened, the warning information of the light box opening will be transmitted to the remote host to remind the staff to check in time to prevent accidents.

[0063] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
