Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power control technology, specifically relating to an energy-saving automatic control device for LED display equipment. Background Technology
[0002] Currently, the power consumption of LED displays in China generally ranges from 200 watts to 1500 watts. The power consumption varies depending on the type of display, the usage environment, and the screen brightness. Most existing LED display devices use automatic switching devices for timed and fixed-point display signal control. This control method only shuts off the display signal source but does not cut off the internal power supply. The internal power module remains constantly running, even when the display is empty or in standby mode. Therefore, the internal power components are prone to aging, leading to a higher failure rate for the LED display device. Furthermore, the continuous power supply from the internal power components results in high power consumption, failing to achieve energy-saving effects. Utility Model Content
[0003] The purpose of this invention is to provide an energy-saving automatic control device for LED display equipment, in order to solve the above-mentioned problems existing in the prior art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model provides a power-saving automatic control device for LED display equipment, including a current sensing module and a timing control module. The current sensing module includes an openable magnetic sensor, and the timing control module includes a timing control board and several timing relays. The timing relays are integrated and installed on the timing control board. The timing control board is electrically connected to the openable magnetic sensor and each timing relay. The output terminal of each timing relay is connected to an output terminal block, which is used to connect to the corresponding power control terminal of the LED display equipment.
[0006] In its application, the device can be installed inside the LED display equipment. The single-phase wire of the LED display equipment's mains power supply line is passed through the induction detection port of the openable magnetic sensor. The openable magnetic sensor detects the current flowing through the cable and transmits the current detection result to the timing control board. The timing control board compares the current detection result to determine whether it is within the normal operating current range. When the timing control board determines that the current detection result is not within the normal operating current range, it indicates that the LED display is in standby mode with a black screen, and the equipment is still in the internal power consumption state. When this state reaches a set duration, or when the current time is within the set shutdown time period, the power-off energy-saving action is automatically initiated. This means that each timing relay is de-energized in sequence, thereby de-energizing the corresponding power control terminal of the LED display equipment electrically connected to the timing relay, so as to completely shut down the internal power supply of the LED display equipment and achieve the energy-saving effect.
[0007] In one possible design, the current sensing module includes a sensing module housing, the timing control module includes a timing module housing, the timing module housing is fixedly connected to the sensing module housing, the openable magnetic sensor is mounted on the sensing module housing, and the timing control board is mounted on the sensing module housing. In application, the relevant components of the current sensing module and the timing control module can be installed separately using the sensing module housing and the timing module housing, respectively. Furthermore, the fixed connection between the timing module housing and the sensing module housing facilitates integrated assembly of the entire device, making installation and use more convenient.
[0008] In one possible design, the sensing module housing has a power output port for outputting power, which is electrically connected to the timing control module. In application, the current sensing module is connected to AC mains power for detection and supply, and this power should be drawn from the AC mains power supply at the front end of the LED display device to prevent the device itself from losing power and becoming inoperable after the automatic power-off action is executed. The power output port on the sensing module housing can output the corresponding power to the timing control module, thus powering the timing control module.
[0009] In one possible design, the timing control board is provided with a power supply terminal for connecting to a power source. This power supply terminal is electrically connected to the timing relays and the timing control board itself. In application, the power supply terminal transmits power to the timing control board and the timing relays, ensuring the timing control module operates normally.
[0010] In one possible design, the induction module housing is provided with control terminals for electrically connecting the openable magnetic sensor to the timing control board. In application, after the openable magnetic sensor performs corresponding current sensing detection, the detection result signal can be transmitted to the timing control board through the control terminals on the induction module housing.
[0011] In one possible design, the timing control board integrates timing control terminals for electrically connecting the opening / closing magnetic sensor to the timing control board. In application, the current sensing detection signal from the opening / closing magnetic sensor can be received via the timing control terminals and transmitted to the timing control board.
[0012] In one possible design, the timing control terminal is also used to connect a local control switch or a remote switch control terminal. In application, the local control switch or remote switch control terminal can send corresponding local control signals or remote control signals to the timing control terminal, which then transmits these signals to the timing control board. This allows the timing control board to control each timing relay to perform corresponding switching actions, achieving local or remote access control of the device.
[0013] In one possible design, the timing module housing and the sensing module housing are provided with mounting grooves, and mounting rails are provided within the mounting grooves, allowing the timing module housing and the sensing module housing to slide relative to the mounting rails. The mounting rails are provided with several mounting holes. In application, the relative positions of the timing module housing and the sensing module housing with respect to the mounting rails can be adjusted by sliding. The entire device is then installed in the corresponding location within the LED display device via the mounting rails. During installation, screws can be used to pass through the mounting holes to fix the mounting rails inside the LED display device.
[0014] Beneficial effects: This utility model can automatically detect the working power supply of LED display equipment, determine the usage status of the LED display, and actively disconnect the internal power supply of the equipment when the display is not in use, so as to reduce the power consumption of the equipment and achieve the purpose of energy saving. At the same time, it can effectively extend the service life of the internal power supply module of the LED display equipment and reduce the failure rate of the equipment. Attached Figure Description

The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0022] Specific details are provided in the following description to provide a complete understanding of the exemplary embodiments. However, those skilled in the art will understand that the exemplary embodiments can be implemented without these specific details. For example, the system may be shown in block diagrams to avoid obscuring the example with unnecessary details.

[0023] Example:
[0024] This embodiment provides a power-saving automatic control device for LED display screen equipment, such as... Figure 1-3 As shown, the device includes a current sensing module and a timing control module. The current sensing module includes an openable magnetic sensor 1, and the timing control module includes a timing control board 6 and several timing relays 5. The timing relays 5 are integrated and installed on the timing control board 6. The timing control board 6 is electrically connected to the openable magnetic sensor 1 and each timing relay 5. The output terminal of each timing relay 5 is connected to an output terminal 9, which is used to connect to the corresponding power control terminal of the LED display device.
[0025] In practical implementation, the device can be installed inside the LED display equipment. The single-phase wire of the mains power supply line of the LED display equipment is passed through the induction detection port of the openable magnetic sensor 1. The openable magnetic sensor 1 is used to detect the current flowing through the cable and transmits the current detection result to the timing control board 6. The timing control board 6 compares the current detection result and determines whether it is within the normal operating current range. When the timing control board 6 determines that the current detection result is not within the normal operating current range, it indicates that the LED display is in standby mode with a black screen and the equipment is still in the internal power consumption state. When this state reaches the set duration, or when the current time is within the set shutdown time period, the power-off energy-saving action is automatically initiated, that is, the timing relays 5 are de-energized in sequence, thereby de-energizing the corresponding power control terminals of the LED display equipment that are electrically connected to the timing relays 5, so as to completely shut down the internal power supply of the LED display equipment and achieve the energy-saving effect.
[0026] Furthermore, the current sensing module includes a sensing module housing 11, and the timing control module includes a timing module housing 7. The timing module housing 7 is fixedly connected to the sensing module housing 11. The openable magnetic sensor 1 is mounted on the sensing module housing 11, and the timing control board 6 is mounted on the sensing module housing 11. In specific implementations, the relevant components of the current sensing module and the timing control module can be installed on the sensing module housing 11 and the timing module housing 7, respectively. The fixed connection between the timing module housing 7 and the sensing module housing 11 facilitates the integrated assembly of the entire device, making installation and use more convenient.
[0027] Furthermore, the sensing module housing 11 is provided with a power output port 10 for outputting power supply, which is electrically connected to the timing control module. The timing control board 6 is provided with a power supply terminal 4 for connecting to the power supply, which is electrically connected to the timing relay 5 and the timing control board 6. In specific implementation, the current sensing module is connected to the mains power for detection and power supply, and the mains power should be taken from the front end of the LED display device to avoid the device itself losing power and becoming inoperable after the device's self-controlled power-off action is executed. The corresponding mains power supply can be output to the timing control module through the power output port 10 on the sensing module housing 11 to power the timing control module. The power supply can be transmitted to the timing control board 6 and the timing relay 5 through the power supply terminal 4 to ensure the normal power supply and operation of the timing control module.
[0028] Furthermore, the sensing module housing 11 is provided with a control terminal 2, which is used to electrically connect the opening and closing magnetic sensor 1 and the timing control board 6. In specific implementation, after the opening and closing magnetic sensor 1 performs corresponding current sensing detection, the detection result signal can be transmitted to the timing control board 6 through the control terminal 2 on the sensing module housing 11.
[0029] Furthermore, the timing control board 6 integrates a timing control terminal 3, which is used to electrically connect the opening and closing magnetic sensor 1 to the timing control board 6. In a specific implementation, the current sensing detection result signal of the opening and closing magnetic sensor 1 can be received through the timing control terminal 3 and transmitted to the timing control board 6.
[0030] Furthermore, the timing control terminal 3 is also used to connect a local control switch or a remote switch control terminal. In specific implementations, corresponding local control signals or remote control signals can be sent to the timing control terminal 3 through the local control switch or the remote switch control terminal. The local control signals or remote control signals are then transmitted to the timing control board 6 through the timing control terminal 3, so that the timing control board 6 controls each timing relay 5 to perform corresponding switching actions, thereby realizing local or remote access control of the device.
[0031] like Figure 3 As shown, after the 220V AC mains input passes through the corresponding main switch, the L-phase wire can be led out and passed through the switchable magnetic sensor 1. The switchable magnetic sensor 1 has a current monitoring range of 0-45A and can provide a custom current value with the help of the current transformer detection function. Taking a setting of 5A as an example, when the LED display power supply is at a low set value for a certain period of time, the sensor can output an I / O signal to the timing control board 6, which in turn controls multiple (e.g., 6) timing relays 5 to shut down in sequence according to the instructions, so that the device stops supplying power. When the user performs local operation or sends a remote control signal to the timing module via computer, the timing module then turns on each timing relay 5 in sequence to supply power to the device.
[0032] Furthermore, the timing module housing 7 and the sensing module housing 11 are provided with mounting grooves, and mounting rails 8 are provided in the mounting grooves, allowing the timing module housing 7 and the sensing module housing 11 to slide relative to the mounting rails 8. The mounting rails 8 are provided with a plurality of mounting holes. In specific implementation, the relative positions of the timing module housing 7 and the sensing module housing 11 with the mounting rails 8 can be slidably adjusted, and the entire device can be installed in the corresponding part of the LED display device through the mounting rails 8. During installation, screws can be used to pass through the mounting holes to fix the mounting rails 8 in the LED display device.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
