Referring to fig. 4, fig. 4 is a flow chart of a second embodiment of the method for monitoring a display screen according to the present invention.
Based on the above first embodiment, step S10 in the method for monitoring the abnormal display of the display screen of this embodiment includes:
step S101: and reading the voltage data sent by the light sensor through the vehicle-mounted SOC.
It should be noted that, the light sensor refers to a device capable of sensing light energy from ultraviolet light to infrared light and converting the light energy into an electrical signal, and the light sensor is a sensing device mainly composed of photosensitive elements and mainly divided into an ambient light sensor, an infrared light sensor, a solar light sensor, an ultraviolet light sensor, and the like, which is not particularly limited in this embodiment.
Further, before the reading of the voltage data sent by the light sensor through the vehicle-mounted SOC, the method further includes: detecting the light intensity of the display screen in real time through the light sensor; when the light intensity change of the display screen is detected, converting the changed light intensity of the display screen into a voltage signal; transmitting the voltage signal to the vehicle-mounted SOC.
The light intensity is the luminous intensity, and is used for representing the physical quantity of luminous flux in a unit solid angle in a given direction of the light source, and the light intensity of the display screen is determined by the screen brightness of the display screen, and the higher the screen brightness is, the higher the light intensity of the display screen is.
It is understood that a voltage signal refers to a signal in the form of a voltage, which is an electrical signal.
In a specific implementation, when the display screen displays abnormal pictures, such as a screen pattern and a black screen, the light intensity of the display screen can be changed, the light intensity after the change of the light sensor is converted into a voltage signal, and the voltage signal is transmitted to the vehicle-mounted SOC.
Further, the reading, by the vehicle-mounted SOC, the voltage data sent by the light sensor includes: receiving a voltage signal transmitted by the light sensor through the vehicle-mounted SOC; and analyzing the voltage signal to obtain the voltage data.
The vehicle-mounted SOC receives the voltage signal transmitted by the photo sensor in real time, analyzes the voltage information into voltage data, and stores the voltage data in the storage unit of the vehicle-mounted SOC.
Step S102: and acquiring a voltage range of the display screen when the display screen displays the display normally.
The method comprises the steps of obtaining the maximum value and the minimum value of the voltage corresponding to the light intensity of the display screen in the normal display of the display screen, and taking the maximum value and the minimum value of the voltage as the upper threshold limit and the lower threshold limit to obtain the voltage range when the display screen displays the normal display.
Step S103: and determining a preset voltage range according to the voltage range when the display screen displays normal.
It should be noted that, if the difference between the voltage value occurring in the screen lighting time and the voltage value when the screen is normally displayed does not exceed the preset value, it is determined that the display screen is normally displayed, and the preset value may be 10% or 20% of the voltage when the screen is normally displayed, which is not particularly limited in this embodiment.
In a specific implementation, according to the upper threshold limit and the lower threshold limit of the voltage range when the display screen displays normally and a preset value, determining a new upper threshold limit and a new lower threshold limit, and obtaining a preset voltage range according to the new upper threshold limit and the new lower threshold limit, for example, the voltage range when the display screen displays normally is 5-10v, the preset value is 20% of the voltage when the display screen displays normally, namely, if the difference between the voltage value appearing in the screen lighting time and the voltage value when the display screen displays normally is not more than 20% of the voltage when the display screen displays normally, the preset voltage range is 4-12v.
Step S104: and comparing the voltage data with a preset voltage range.
The voltage data is compared with an upper threshold limit and a lower threshold limit of the preset voltage range respectively.
Step S105: and judging whether the voltage data is in the preset voltage range or not.
It should be noted that, if the voltage data is greater than or equal to the lower threshold limit of the preset voltage range and less than or equal to the upper threshold limit of the preset voltage range, it indicates that the voltage data is within the preset voltage range, and if the voltage data is less than the lower threshold limit of the preset voltage range or greater than the upper threshold limit of the preset voltage range, it indicates that the voltage data is not within the preset voltage range.
Step S106: and if so, judging that the display screen displays normally.
It should be noted that, if the voltage data is within the preset voltage range, the display screen is indicated to display normally.
Further, after the determining whether the voltage data is within the preset voltage range, the method further includes: if not, judging that the display screen is abnormal; the IO port of the vehicle-mounted SOC is controlled to keep high level, so that the power relay is not powered down, and the display screen power supply is controlled to be in a continuous on state; and executing the step of sending a control instruction to the camera module when the display screen is detected to be abnormal.
The power relay is an electric appliance that turns on or off an output circuit to be controlled when an input amount (such as voltage, current, temperature, etc.) reaches a prescribed value.
It can be understood that one IO port of the vehicle-mounted SOC is taken, the relay is repeatedly pulled up and pulled down at regular time, the relay is opened and closed at regular time, and when the relay is required not to be powered down, the IO port of the vehicle-mounted SOC is controlled to be pulled up and in a high-level state.
In the specific implementation, the light sensation is changed along with the brightness and is transmitted to different voltage values of the vehicle-mounted SOC, the vehicle-mounted SOC records complete voltage value data from normal power-on to power-off, and in the later power-on and power-off process, if the voltage value in the lighting time is more than twenty percent different from the normal voltage value recorded before, the vehicle-mounted SOC judges that the display screen is abnormally displayed at the moment, synchronously controls the IO port to be pulled up and is in a high-level state, and the relay is not powered off and sends a control instruction to the camera module through the IIC channel.
In this embodiment, the voltage data sent by the light sensor is read through the vehicle-mounted SOC; acquiring a voltage range of the display screen when the display is normal; determining a preset voltage range according to the voltage range when the display screen displays normal; comparing the voltage data with a preset voltage range; judging whether the voltage data is in the preset voltage range or not; and if so, judging that the display screen displays normally. Through the mode, whether the display screen displays normally or not is determined according to the voltage data of the display screen, and the display screen can be detected all the day through the detection of the light sensor, so that the labor is saved.
Referring to fig. 5, fig. 5 is a flow chart of a third embodiment of the method for monitoring a display screen according to the present invention.
Based on the above first embodiment, step S30 in the method for monitoring the abnormal display of the display screen of this embodiment includes:
step S301: and intercepting an abnormal display picture of the display screen in the monitoring video.
If the abnormal display times are only required to be recorded and the abnormal phenomenon is not required to be kept, when the display screen is abnormally displayed, the camera is controlled to shoot, the power relay is controlled to be normally electrified and powered off, and if the abnormal phenomenon is required to be kept, the camera is controlled to record the video, and the power relay is controlled to be electrified.
Step S302: and determining the abnormal display type of the display screen according to the abnormal display picture.
The abnormal display type includes a screen pattern, a black screen, etc., where the screen pattern means that the screen has stripes, spots or color blocks different from the normal color, or that the screen pattern is reversed, disordered, jittered, distorted, etc., and the black screen is completely black, and does not display a picture, as the screen pattern is not powered on, which is not particularly limited in this embodiment.
Step S303: and determining an up-down voltage measurement mode according to the abnormal display type.
It should be noted that, the abnormal modes of power up and power down of different fault types are different, and the power up and power down voltage measurement is that of a power up and power down display screen, and the power up and power down mode includes power up and power down times, power up and power down time intervals and the like.
Step S304: and controlling the display screen to be powered on and powered off through the power relay according to the upper and lower voltage measurement mode until the abnormal display picture is reproduced.
And controlling the display screen to be powered up and down through the power relay according to the up-down voltage measurement mode until the abnormal display picture is reproduced, and testing the voltage when the abnormal display picture is reproduced.
Further, if an abnormal display screen appears on the display screen in the monitoring video, after the abnormal display screen is reproduced by the upper and lower voltage measurement, the method further includes: controlling video signal transmission between the central control circuit board and the display screen, and monitoring the display picture of the display screen in real time; and determining whether a video link between the central control circuit board and the display screen is normal according to the display picture of the display screen, and performing fault location.
