Each circuit that elevating system that sets up in the shell needs and each circuit of multimedia exhibition mechanism all can be drawn forth by the shoulder hole, guarantees that the business turn over position of all circuits of this system all has good waterproof performance.
Because the system provided by the application is mainly used for outdoor advertisement display, and the advertisement displayed by the traditional outdoor advertisement equipment is usually played circularly according to a preset sequence, the interested advertisement can not be displayed to the user in a targeted manner. To solve this problem, an embodiment of the present application may provide that, as shown in fig. 5, the multimedia presentation mechanism includes:
a storage unit 33, the storage unit 33 being configured to store a plurality of advertisement information; the storage unit is used for storing a plurality of preset advertisements, and the storage unit can be also in communication connection with the central server and used for receiving and storing the advertisements sent by the central server.

And the control unit 36 is configured to control a display time of the current advertisement information displayed by the display unit 34, where the display time is determined according to a time that the face image acquired by the photographing unit stays in front of the display unit. Specifically, the acquired front face image is identified, and the number of people watching the display unit and the time are judged;
and when the number of people and/or the time meet the preset number, controlling the display unit to continuously display the current advertisement information.
For example, it is preset that five advertisements are played in a circulating manner, and when one advertisement is played for 5 minutes, the next advertisement is played until the advertisement is circulated to the next advertisement. When some pedestrians are interested in a certain advertisement, it is necessary to repeatedly play the interested advertisement for many times to the pedestrians, or to play the advertisement related to the advertisement preferentially.
In a specific implementation, the camera unit acquires a front face image of the display unit in real time during the display of the advertisement by the display unit, and the reason for capturing the front face image of the display unit is to determine the degree of preference of a pedestrian for each advertisement content by detecting the number of people who gaze at the currently displayed advertisement content and the time taken to watch the advertisement.
Next, a face recognition algorithm is performed on the captured image to detect the number of people gazing at the display device and the time of gazing. Here, the subject image is read using a suitable face recognition algorithm to create a complete image, and then a cascade of classifiers is performed. In addition, the face recognition algorithm captures a face of a person in a photographed image, detects eyes in the captured face, and passes a sensed eye gaze direction of the pedestrian. That is, an eye portion is detected from a face of a person by using a face recognition algorithm, and the number of persons who gaze at the display device and the time of gazing are detected.
When the number of people watching the advertisement and/or the watching time meet/meet the preset number of people and/or the preset watching time in the process of playing the advertisement on a certain day, determining that the advertisement is liked by pedestrians.
Next, the control unit controls the advertisement contents played on the display unit and the display time and frequency of each advertisement content. The advertisement is played on the display device in a circulating way, the playing times can be set according to a preset value, for example, the playing times can be input into the control unit in advance to be three times, and therefore when certain advertisement is determined to be liked by pedestrians, the advertisement can be played in a circulating way for three times. Of course, when other advertisements are played in a loop after the three-pass playing is completed, if it is detected in one loop that the number of viewers and the viewing time of the advertisement are still the largest among all the advertisements, the number of times of the loop playing can be increased when the advertisement is played next time. Of course, the storage unit and the control unit may also be connected to a remote server, and when the remote server receives a determination that a certain advertisement is popular, the remote server may send an advertisement similar to the certain advertisement to the storage device, so that the display unit plays the similar advertisement received by the storage device. Through the multimedia display mechanism, the purpose of accurately putting advertisements to viewers can be achieved. Meanwhile, the camera required by the multimedia display mechanism can be arranged on the base, and the integral waterproof performance of the system cannot be influenced.
In a word, the multimedia system who possesses intelligent raising and lowering functions that this application provided, simple structure is reasonable, installation convenient to use. The waterproof mechanism has excellent waterproof performance, can realize automatic contraction in rainfall, and ensures that the multimedia display mechanism cannot be attacked by rainwater. The display mechanism can achieve the purpose of accurately putting advertisements and is worthy of large-area popularization and use.
