Abstract
The utility model discloses an automatic LED-panel television shade and brightness detecting device which can judge the environmental condition correctly and improve the brightness adjusting accuracy. The technical scheme is as follows: the automatic LED-panel television shade and brightness detecting device is characterized by comprising master control equipment, a plurality of shade detecting sensors and a plurality of brightness detecting sensors, wherein the master control equipment is connected with the shade detecting sensors and the brightness detecting sensors respectively through buses. The brightness detecting sensors and the shade detecting sensors are of the same level without priority processing.
Description
Technical field
The utility model belongs to that LED panel TV is covered and brightness automatic detection device field, especially a kind ofly can correctly judge ambient conditions, improves the coverage of LED panel TV and the brightness automatic detection device of brightness regulation accuracy.
Background technology
At present, television set brightness brake control function commonly used, but this function is mostly seldom used, has only a transducer, if this transducer is covered or other factors breaks down, will cause the control system erroneous judgement, regulate thereby can carry out mistake brightness.
The utility model content
The purpose of this utility model provides a kind ofly can correctly judge ambient conditions, improves the LED panel TV of brightness regulation precision and covers and the brightness automatic detection device.
The technical solution of the utility model is: LED panel TV is covered and the brightness automatic detection device, it is characterized in that being made up of main control device, several coverage detecting sensors and several brightness detecting sensors, wherein main control device is connected with the brightness detecting sensor with described coverage detecting sensor respectively by bus.
Described brightness detecting sensor, coverage detector are transducer at the same level, no processed.
All coverage detecting sensors and brightness detecting sensor are carried out self and are periodically detected current state, if find certain be in abnormal working position constantly initiatively send warning message and parameter to main control device, main control device has received this warning message, interrupts the timely process information of current operation.
Effect of the present utility model is: LED panel TV is covered and the brightness automatic detection device, form by main control device, several coverage detecting sensors and several brightness detecting sensors, main control device is connected with the brightness detecting sensor with described coverage detecting sensor respectively by bus, forms multiple spot brightness and cover to detect to solve control system.Multiple spot brightness and coverage detect the problem that can solve the error of control system brightness regulation, after a test point is covered, can also carry out algorithm process with reference to the feedback information of other test point, thus can the current ambient conditions of right judgement, improve the accuracy of brightness regulation.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is that LED panel TV is covered and brightness automatic detection device circuit block diagram;
Fig. 2 is that LED panel TV is covered and brightness automatic detection device workflow diagram.
Embodiment
Among Fig. 1, LED panel TV is covered and the brightness automatic detection device, be made up of main control device, several coverage detecting sensors and several brightness detecting sensors, wherein main control device is connected with the brightness detecting sensor with described coverage detecting sensor respectively by bus.Brightness detecting sensor, coverage detector are transducer at the same level, no processed.All coverage detecting sensors and brightness detecting sensor are carried out self and are periodically detected current state, if find certain be in abnormal working position constantly initiatively send warning message and parameter to main control device, main control device has received this warning message, interrupts the timely process information of current operation.
Among Fig. 2, the structure that LED panel TV is covered and brightness detects automatically, the core control section is a main control device, its transducer is divided into the brightness detecting sensor and covers detecting sensor, main control device sends order by communication bus to each sensor node, gather corresponding environment parameter, at first main control device sends brightness to the brightness detecting sensor successively respectively and detects instruction, after the brightness detecting sensor is received instruction, the image data parameter, and feed back to main control device, this moment main control device whether will detect this transducer be last brightness detecting sensor, if not, then continue sending brightness detects and instructs next brightness detecting sensor, be last brightness detecting sensor if detect this transducer, then main control device will send successively to cover to detect and instruct each to cover detecting sensor, so that whether detect screen is covered, after last coverage detecting sensor feeds back to main control device to the data that detect, main control device is according to the detection data of detected each transducer, by the programmed algorithm that configures, determine the work brightness of present LED panel TV.
Claims (2)
1.LED the panel TV is covered and the brightness automatic detection device, it is characterized in that being made up of main control device, several coverage detecting sensors and several brightness detecting sensors, wherein main control device is connected with the brightness detecting sensor with described coverage detecting sensor respectively by bus.
