Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
It should be noted that in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1, the flowchart is a workflow diagram of a control method of an image reading device based on light sensing according to a specific embodiment of the present invention, where the image reading device includes an image reading lamp and a medical display, and the image reading device in this embodiment is a medical display. The method comprises the following steps:
acquiring the visible spectrum intensity of a film placing area of the medical display, acquiring the infrared spectrum intensity of the film placing area, and detecting and acquiring a film inserting signal of the medical display.
And step two, when the medical image film is detected to be inserted into the film slot below the display screen of the medical display, the medical staff can be determined to be reading the film at the moment, and the medical display enters a film reading working state, namely, a film reading lamp mode is started. In the reading lamp mode, the display screen of the medical display wholly or partially displays a pure white picture.
And step three, when the situation that the medical image film is inserted into the film slot below the display screen of the medical display is not detected, whether medical staff is reading the film cannot be determined.
In this case, if the acquired visible spectrum intensity is lower than the preset environmental spectrum intensity threshold, it indicates that the film placement area of the medical display is blocked to cause brightness reduction; meanwhile, the acquired infrared spectrum intensity is higher than a preset infrared spectrum intensity threshold value, which indicates that the infrared radiation is enhanced due to the fact that a human body is close to the vicinity of a film placing area of the medical display. At this time, it can be inferred that the medical staff may be performing the reading operation, and the medical display turns on the reading lamp mode.
If the acquired visible spectrum intensity is higher than a preset environmental spectrum intensity threshold value, indicating that a film placing area of the medical display is not shielded by the film; if the acquired infrared spectrum intensity is lower than the preset infrared spectrum intensity threshold value, it shows that the infrared radiation near the film placing area of the medical display is not obviously enhanced, namely no medical staff approaches. In any case, it can be inferred that, at this time, it is impossible for the medical staff to perform the reading operation, the medical display enters the reading waiting state, i.e., exits the reading lamp mode, and the brightness of the display screen is significantly reduced. At this time, in order to avoid the damage of the display screen of the medical display due to the long-time display of the static picture, the medical display starts the dynamic picture mode. The dynamic picture mode is that a plurality of static pictures are pre-stored in a chip of a display drive board, and when the dynamic picture mode is started, the display automatically calls the pre-stored pictures to carry out circular display.
As shown in fig. 2, the present invention provides a system block diagram of a control device of an image reading apparatus based on light sensing, which includes: the input end of the microprocessor is respectively connected with the input ends of the ambient light sensor and the infrared light sensor, and the output end of the microprocessor is connected with a driving plate of the medical display; the input end of the microprocessor is also connected with a film sensing module.
The environment light sensor is used for converting the illumination intensity of a film placing area of the medical display into a digital signal to be output, a photosensitive diode is integrated in the sensor, photosensitive current is converted into digital quantity to be output by the photosensitive diode, and the digital quantity represents the measured value of the visible spectrum intensity of the film placing area. As the preferred scheme, the ambient light sensor is installed in a film placing area of the medical display, and when a film is placed in the film placing area, the ambient light sensor is covered by the film, so that the difference value of the visible spectrum intensity measured and obtained by the ambient light sensor when the film is placed and when the film is not placed is larger, and false triggering is avoided.
The infrared light sensor, also called as a human body induction sensor, is an automatic control module based on an infrared technology, when a human body enters an induction range, the sensor can detect and acquire the change of the infrared spectrum of the human body and automatically output a digital quantity signal, and when the human body leaves the induction range, the sensor outputs a state before recovery.
The film sensing module is used for detecting whether a film is inserted into a film slot below the display screen of the medical display. In this embodiment, the film sensing module is a logic level switch, and the logic level switch is connected to a key disposed in the film slot. When the film is inserted, the key is pressed, and the logic level is changed from high to low and transmitted to the microprocessor; when the film is removed, the keys spring back to restore and the logic level goes from low to high and is passed to the microprocessor.
The microprocessor is a control core module of the device. When the logic level switch inputs a low level, the microprocessor controls the medical display to start a film reading lamp mode; when the logic level switch inputs a high level, the microprocessor controls the medical display in real time according to the illumination intensity acquired by the ambient light sensor and the infrared light intensity acquired by the infrared light sensor.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
