Example 1
Fig. 1 is a schematic structural diagram of a power regulation system according to a first embodiment of the present invention.
The power regulation system 10 comprises a control end, at least one liquid crystal rear projection unit 13 and control boxes 12 corresponding to the liquid crystal rear projection units 13 one by one.
The control terminal includes an advertisement server 111 and a user terminal 112.
The advertisement server 111 is used for controlling all the control boxes 12 in the whole power supply regulation and control system 10, and further controlling the power supply on-off, the power regulation and the like of the liquid crystal rear projection unit 13 through the control boxes 12.
The advertisement server 111 is also used to authorize the user terminal 112 to control one or more control boxes 12.
Alternatively, the advertisement server 111 is used to control all the control boxes 12 in a general area, such as all the control boxes 12 in the whole power regulation system 10; the advertisement server 111 is further configured to authorize the user terminal 112 to control all the control boxes 12 in one or more sub-areas in the total area, or the advertisement server 111 authorizes the user terminal 112 to control one or more control boxes 12 in one or more sub-areas in the total area.
The user terminal 112 is configured to send an advertisement service request to the advertisement server 111.
The user terminal 112 may include a mobile terminal, a palm terminal, and the like.
After receiving the advertisement service request, the advertisement server 111 determines whether to accept the advertisement playing request of the user terminal 112 according to the playing plan of the liquid crystal rear projection unit 13.
Preferably, the advertisement server 111 is further configured to, after receiving the advertisement content, first perform an audit on the advertisement content to confirm whether the advertisement content is qualified.
For example, the advertisement server 111 comprehensively examines the advertisement contents and the presentation forms, whether the subject qualification of the advertiser is legal, whether the advertisement publicity conforms to the truth principle, whether the words or pictures falsely constitute the facts or hide the facts, whether the exaggeration publicity gives the consumers a place to be deceived, whether the words or pictures misunderstand to the consumers are present, and whether the contents are explicitly prohibited from being present in the advertisement law.
The advertisement server 111 may also transmit the received advertisement content to an advertisement examination agency for examination.
If the advertisement content is qualified, the advertisement server 111 searches whether the liquid crystal rear projection unit 13 is available according to the playing plans of all the liquid crystal rear projection units 13.
If the liquid crystal rear projection unit 13 is available, the advertisement server 111 sends confirmation acceptance information and a bill for fee to the user terminal 112.
The user terminal 112 receives the confirmation acceptance information and the fee information, and pays the fee bill according to the input operation of the user.
The advertisement server 111 adds the advertisement contents to a play list upon receiving payment information of the user terminal 112.
The advertisement server 111 is configured to send an advertisement play list of the liquid crystal rear projection unit 13 to the control box 12.
When the advertisement playlist is changed, the advertisement server 111 is configured to send the changed advertisement playlist to the control box 12. Alternatively, the advertisement server 111 sends the advertisement playlist to the control box 12 at preset intervals.
The control box 12 updates the advertisement play list stored in the storage module 122 according to the received changed advertisement play list. Alternatively, the control box 12 stores the received changed advertisement playlist in the storage module 122 and deletes the previously stored advertisement playlist.
The control box 12 controls the working mode of the liquid crystal rear projection unit 13 according to the advertisement play list, thereby reducing the waste of electric energy and saving electric power resources.
The operating modes may include a standby mode, a shutdown mode, an operational mode, and the like.
The advertisement server 111 is further configured to send an opening instruction to the control box 12 according to the advertisement service request sent by the user terminal 112, and the control box 12 turns on a power switch of the corresponding liquid crystal rear projection unit 13 according to the opening instruction.
For example, the control box 12 determines whether the liquid crystal rear projection unit 13 corresponding to the start instruction is in a power-off state according to the start instruction sent by the advertisement server 111, and if the liquid crystal rear projection unit 13 is in the power-off state, the control box 12 turns on the power switch of the corresponding liquid crystal rear projection unit 13 according to the start instruction, so that the liquid crystal rear projection unit 13 is in the power-on state, and subsequent advertisement delivery is facilitated.
Fig. 2 is a schematic structural diagram of a control box according to an embodiment of the present invention.
The control box 12 comprises a microprocessor 121, a memory module 122 and a power driving module 123.
The microprocessor 121 is configured to receive the advertisement playlist of the liquid crystal rear projection unit 13 sent by the advertisement server 111, and send the advertisement playlist to the storage module 122.
The storage module 122 is configured to store the received advertisement playlist.
The memory module 122 includes a RAM portion and a ROM portion.
It should be understood that a Random Access Memory (RAM), also called "RAM", is an internal memory, also called main memory, for directly exchanging data with the CPU. It can be read and written at any time, and is fast, usually used as temporary data storage medium of operating system or other running program.
It should be understood that ROM is a short for Read-Only Memory (Read-Only Memory) and is a solid-state semiconductor Memory capable of reading Only data stored in advance. The property is that once the data is stored, it cannot be changed or deleted. It is commonly used in electronic or computer systems where the data is not required to be changed frequently and the data is not lost due to power down.
The microprocessor 121 compares each idle period in the advertisement playlist with a preset time threshold, if the idle period is greater than or equal to the preset time threshold, the microprocessor 121 sends a mode switching signal to the power driving module 123, and the power driving module 123 controls the liquid crystal rear-projection unit 13 to reduce power input and enter a shutdown mode according to the received mode switching signal; if the idle period is less than the preset duration threshold, the power driving module 123 controls the liquid crystal rear projection unit 13 to reduce power input and enter a standby mode according to the received mode switching signal.
The idle time interval is a time interval between any two adjacent recorded advertisement playing time intervals in the advertisement playing list.
For example, if the idle period is relatively long, such as 3.5h, and the preset time threshold is 3h, in order to reduce the power consumption of the liquid crystal rear projection unit 13, the corresponding liquid crystal rear projection unit 13 enters the shutdown mode in the idle period. If the idle time is a small time interval, such as 1h, and the preset time threshold is 3h, then, in order to reduce the power consumption of the liquid crystal rear projection unit 13, in the idle time, the corresponding liquid crystal rear projection unit 13 enters a standby mode, so that the liquid crystal rear projection unit 13 is quickly turned on in the next advertisement playing time, and the device response time is reduced.
In addition, when the liquid crystal rear projection unit 13 is in the operation mode, the control box 12 may further specifically divide the operation mode into a video playing mode, a slide show mode, a text browsing mode, and the like according to the difference of the advertisement contents in the advertisement playing list.
For example, when the advertisement content being played is a video, the microprocessor 121 sends a control instruction to enable the power driving module 123 to adjust power output, so that the corresponding liquid crystal rear projection unit 13 enters a high-performance video playing mode;
when the advertisement content is a slide show, the microprocessor 121 sends a control instruction to enable the power driving module 123 to adjust the power output, so that the corresponding liquid crystal rear projection unit 13 enters a slide show mode;
when the advertisement content is a text, the microprocessor 121 sends a control command to enable the power driving module 123 to adjust the power output, so that the corresponding liquid crystal rear projection unit 13 enters a low-performance text browsing mode.
In addition, the correspondence between the advertisement content and the output power may also be described by a table.
| Advertising content | Output power (w) |
| Character(s) | 65 |
| Slide show | 120 |
| Video | 300 |
For example, when the advertisement content is a text, the power driving module 123 controls the corresponding liquid crystal rear projection unit 13 to control the output power at 65w, and enters a text browsing mode;
when the advertisement content is a slide, the power driving module 123 controls the corresponding liquid crystal rear projection unit 13 to control the output power at 120w, and enters a slide mode;
when the advertisement content is a video, the power driving module 123 controls the corresponding liquid crystal rear projection unit 13 to control the output power at 300w, and enters a video playing mode.
Fig. 3 is a schematic structural diagram of another control box according to an embodiment of the present invention.
Compared to fig. 2, the control box 12 further includes an ambient light sensor 124 and a power detection module 125.
When the liquid crystal rear-projection unit 13 is in the operation mode, the ambient light sensor 124 is configured to acquire light intensity data of an environment around the liquid crystal rear-projection unit 13 and send the light intensity data to the control box 12.
The control box 12 adjusts the light transmittance of the liquid crystal rear projection unit 13 according to the received light intensity data.
For example, the control box 12 compares the light intensity data with a preset light intensity threshold, if the light intensity data is less than or equal to the light intensity threshold, the control box 12 sends an adjustment instruction to the power driving module 123, and the power driving module 123 controls the liquid crystal rear-projection unit 13 to reduce power output according to the received adjustment instruction, so as to reduce the atomization degree of the liquid crystal glass and improve the light transmittance of the liquid crystal rear-projection unit 13;
if the light intensity data is greater than the light intensity threshold, the control box 12 sends an adjustment instruction to the power driving module 123, and the power driving module 123 controls the liquid crystal rear projection unit 13 to increase power output according to the received adjustment instruction, so that the atomization degree of the liquid crystal glass is improved, and the light transmittance of the liquid crystal rear projection unit 13 is reduced.
By the power supply control mode, the liquid crystal rear projection unit 13 is adapted to the current environment, the best display effect is achieved, the power consumption of the equipment is reduced, and the electric power energy is saved.
In addition, the relationship between the light intensity data and the light transmittance may also be represented by a table.
| Luminous intensity (candela) | Light transmittance |
| 100 | 40％ |
| 300 | 0％ |
For example, if the light intensity of the ambient environment obtained by the ambient light sensor 124 is 100 candelas, and if the light intensity threshold is set to 200, the power driving module 123 controls the liquid crystal rear-projection unit 13 to reduce the power output, and adjusts the light transmittance of the liquid crystal rear-projection unit 13 to be about 40%;
if the light intensity of the ambient environment obtained by the ambient light sensor 124 is 300 candelas, and if the light intensity threshold is set to 200, the power driving module 123 increases the power output and adjusts the light transmittance of the liquid crystal rear projection unit 13 to 0%.
The power detection module 125 is configured to monitor a power supply state of the liquid crystal rear projection unit 13, and send a power supply abnormality report to the advertisement server 111 when the power supply state is abnormal, and the advertisement server 111 notifies a maintenance unit to maintain the abnormality after receiving the power supply abnormality report.
For example, when a power supply is disconnected or a short circuit is unstable locally or in a single liquid crystal rear projection unit 13, the power detection module 125 is configured to collect power supply on-off state data and voltage data of the liquid crystal rear projection unit 13, analyze the power supply on-off state data and the voltage data, and determine whether the liquid crystal rear projection unit 13 is in an abnormal power supply state, if the power supply state is abnormal, the advertisement server 111 sends the abnormal power supply report to a third-party maintenance unit, so as to notify the maintenance unit to maintain the abnormal problem, ensure timely handling of the fault, and improve the working efficiency of the entire power regulation and control system 10.
The control box 12 may further include a switch driving module, and the switch driving module is configured to control a power switch of the liquid crystal rear projection unit 13 to be turned on or off according to a power on/off command sent by the control box 12.
The control box 12 may also include a power module for providing power to other modules within the control box 12.
The power module may be a battery, such as a dry battery pack, a button battery pack, etc., or a power charging interface, and is used in cooperation with an external power adapter, so that external alternating current is converted into direct current to be stored in the energy storage module, and the direct current is used for supplying power to the control box 12.
Preferably, the power module of the control box 12 may further include an uninterruptible power supply part for supplying power to the power detection module 125 upon sudden power failure, so that the power detection module 125 transmits a power supply abnormality report to the advertisement server 111.
In this embodiment, the control box 12 and the liquid crystal rear projection unit 13 are independent devices, and are powered by respective power modules. The control box 12 is connected with the liquid crystal rear projection unit 13, so that the control box 12 regulates and controls the power of the liquid crystal rear projection unit 13 and switches on and off a power switch. By the method, the application range of the control box 12 is expanded, the control box 12 in one system can be applied to other systems, one control box 12 can be applied to different liquid crystal rear projection units 13, the life cycle of the control box 12 is prolonged, and the application scene of the control box 12 is expanded.
In other embodiments of the present invention, the control box 12 may be integrated with the liquid crystal rear projection unit 13, and a power module is used to supply power to the control box 12 and the liquid crystal rear projection unit 13. In this way, the hardware module of the control box 12 is simplified, and the production cost is saved.
Preferably, the control priority of the advertisement server 111 to the control box 12 is higher than the control priority of the user terminal 112.
For example, when the advertisement server 111 and the user terminal 112 simultaneously control a control box 12, the control box 12 preferentially executes a control instruction issued by the advertisement server 111.
Preferably, when the advertisement server 111 authorizes a plurality of user terminals 112 to control the same control box 12, the advertisement server 111 grants the corresponding user terminal 112 the control right of the control box 12 connected to the liquid crystal rear-projection unit 13 according to the play list of the liquid crystal rear-projection unit 13.
The following table shows a play list of the liquid crystal rear projection unit 13.
| Advertisement playing time interval | Advertising content |
| 2018.05.01 10:00-2018.05.01 12:00 | Advertisement 1 |
| 2018.05.01 13:00-2018.05.01 15:00 | Advertisement 2 |
| 2018.05.01 15:00-2018.05.01 16:30 | Advertisement 3 |
For example, the advertisement server 111 authorizes the user terminal C1 of advertisement 1, the user terminal C2 of advertisement 2, and the user terminal C3 of advertisement 3 to simultaneously control the same control box 12, and the advertisement server 111 grants the highest control priority to the user terminal C1 in the playing time interval 2018.05.0110: 00-2018.05.0112: 00 according to the advertisement playing time intervals of the three user terminals, wherein the user terminal C2 and the user terminal C3 do not have the control authority of the control box 12 in the playing time interval; in the 2018.05.0113: 00-2018.05.0115: 00 playing period, the user terminal C2 is granted the highest control priority, and in the playing period, the user terminal C1 and the user terminal C3 do not have the control authority of the control box 12; during the playback period 2018.05.0115: 00-2018.05.0116: 30, user terminal C3 is granted the highest priority of control, and during this playback period, user terminal C1 and user terminal C2 do not have control authority over the control box 12.
The advertisement server 111 is a core management part of the power regulation system 10 and is responsible for implementing unified management of all the control boxes 12 in the control area.
In addition, the advertisement server 111 may also receive back the master control authority, distribute the control authority to each user terminal 112, and each user terminal 112 controls the corresponding control box 12, so as to realize intelligent regulation and control of the power of the liquid crystal rear projection unit 13 connected with the control box 12.
The advertisement server 111 can also recover the control authority of all the user terminals 112, and after the authority is recovered, the user terminals 112 can not execute any control operation on the control box 12.
In addition, the control box 12 may further include a wireless module for implementing remote data transmission among the advertisement server 111, the user terminal 112, the control box 12 and the liquid crystal rear projection unit 13.
Fig. 4 is a schematic structural diagram of a liquid crystal rear projection unit according to a first embodiment of the invention.
The liquid crystal rear-projection unit 13 includes a power supply module 131, a liquid crystal glass module 132, a projection module 133, and a speaker module 134.
The power module 131 is used to provide power supply for other modules in the liquid crystal rear projection unit 13.
The power module 131 supplies power to all modules in the liquid crystal rear projection unit 13, and can output multiple voltages to supply power of different voltages to different modules.
The liquid crystal glass module 132 is in a transparent state or an atomized state by being turned on or off with the power module 131.
