[0024] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0025] Figure 1 This is a principle block diagram of a display screen control system for integrated media advertising based on an entrance and exit access device provided by an embodiment of the present disclosure. Figure 1-Figure 2 The integrated media advertising display screen control system based on the entrance and exit passage device includes a timer, which is used to control the display switching of advertising pictures and / or advertising videos, and also includes a slow start circuit, which includes a switch tube Q1, a resistor R1 and a capacitor C1.

[0026] The first end of the resistor R1 is connected to the power supply, the second end of the resistor R1 is grounded through the capacitor C1, the second end of the resistor R1 is connected to the control end of the switch tube Q1, the first end of the switch tube Q1 is connected to the first end of the resistor R1, the second end of the switch tube Q1 is used to connect to the first power supply end of the display screen, and the second power supply end of the display screen is grounded.

[0027] In the disclosed embodiment, by setting a timer to control the timed switching of advertising images and / or advertising videos, the display screen can also be controlled to be turned off at a scheduled time, so that the display screen can get a short rest, alleviate the heating problem of the display screen, avoid a series of problems caused by the heating of the display screen, and thus extend the service life of the display screen.

[0028] At the same time, in order to avoid the electric energy shock when the display screen is powered on, the present embodiment is provided with a slow start circuit. When the power is just turned on, the power supply charges the capacitor C1 through the resistor R1. As the capacitor C1 is charged, the voltage at the control end of the switch tube Q1 gradually increases, the switch tube Q1 is gradually turned on, and the voltage applied to the display screen gradually increases, thereby avoiding the shock to the display screen caused by the sudden change of voltage.

[0029] It should be noted that the display screen control system for integrated media advertising based on the entrance and exit access equipment in this embodiment can be used to drive a variety of display screens, including: multiple LCD TVs spliced ​​together (including a single one), large LED screens, holographic stereo screens, straight pole screens, etc.

[0030] Further, refer to Figure 2 An inductor L1 is arranged between the first end of the resistor R1 and the power supply, and an inductor L2 is arranged between the second end of the switch tube Q1 and the display screen.

[0031] In this embodiment, the inductor L1 and the inductor L2 are provided to play the role of current filtering, thereby avoiding current shock to the display screen when the power is just turned on.

[0032] Further, refer to Figure 2 A switch tube Q2 is provided between the first end of the resistor R1 and the power supply.

[0033] A first end of the switch tube Q2 is connected to a power source, a second end of the switch tube Q2 is connected to a first end of the resistor R1 , and a control end of the switch tube Q2 is connected to a first output end of the main control unit.

[0034] In this embodiment, the main control unit can control the switch tube Q2 to be turned on or off at a fixed time by sending high and low level signals to the control end of the switch tube Q2, thereby controlling the display screen to be powered off and rested at a fixed time.

[0035] Further, refer to Figure 1 The display screen control system for integrated media advertising based on the entrance and exit passage device also includes a vehicle identification module for real-time vehicle detection; the output end of the vehicle identification module is connected to the first input end of the main control unit.

[0036] In this embodiment, the vehicle identification module can detect vehicle information in real time. When a vehicle passes through the entrance and exit traffic equipment (such as a gate), the vehicle identification module sends the vehicle information to the main control unit. The main control unit controls the display screen to stop the current advertisement playback and display the vehicle information on the display screen.

[0037] Further, refer to Figure 1 The integrated media advertising display screen control system based on the entrance and exit access equipment also includes:

[0038] A temperature detection module is used to detect the temperature of the display screen, and an output end of the temperature detection module is connected to the second input end of the main control unit;

[0039] The TEC module is used to control the temperature of the display screen, and the control end of the TEC module is connected to the second output end of the main control unit.

[0040] In this embodiment, an ambient temperature that is too high or too low will affect the working performance of the display screen. Accordingly, this embodiment is provided with a temperature detection module that can monitor the temperature of the display screen in real time and send it to the main control unit. When the temperature of the display screen exceeds the set range, the main control unit sends a control instruction to the TEC module (thermoelectric cooler module) to adjust the working state of the TEC module to adjust the temperature of the display screen.

[0041] Further, refer to Figure 1 A first comparator and a second comparator are arranged between the temperature detection module and the main control unit, the non-inverting input terminal of the first comparator is connected to the output terminal of the temperature detection module, the inverting input terminal of the first comparator is connected to the first reference voltage, the inverting input terminal of the second comparator is connected to the output terminal of the temperature detection module, and the non-inverting input terminal of the second comparator is connected to the second reference voltage,

[0042] The output end of the first comparator is connected to the third input end of the main control unit, and the output end of the second comparator is connected to the fourth input end of the main control unit.

[0043] In this embodiment, when the temperature of the display screen is less than the upper temperature limit, the output of the temperature detection module is less than the first reference voltage, and the first comparator outputs a low-level signal to the third input terminal of the main control unit; when the temperature of the display screen is greater than the upper temperature limit, the output of the temperature detection module is greater than the first reference voltage, and the first comparator outputs a high-level signal to the third input terminal of the main control unit. When the temperature of the display screen is greater than the lower temperature limit, the output of the temperature detection module is greater than the second reference voltage, and the second comparator outputs a low-level signal to the fourth input terminal of the main control unit; when the temperature of the display screen is less than the lower temperature limit, the output of the temperature detection module is less than the second reference voltage, and the second comparator outputs a high-level signal to the fourth input terminal of the main control unit.

[0044] On this basis, when the third input terminal of the main control unit receives a high level signal, the cooling temperature of the TEC module is lowered, and when the fourth input terminal of the main control unit receives a high level signal, the heating temperature of the TEC module is increased.
