Description
Technical Field
The invention relates to the technical field of information, in particular to a method and a device for displaying an equipment running state.
Background
For devices requiring long-term continuous operation, one or more LED lamps are usually used as device operation status indicator lamps, which can display the current basic operation status of the device, such as power status indicator lamps. However, for more complex devices, such as a communication base station server, there are many functional modules, and the corresponding status information is also very much. This includes the on-off of various communication interfaces, the load of the processor and the memory, or the state information such as the internal temperature of the case, which brings a great challenge to the display of the device operation state information.
Generally we can see three ways to display a large amount of state information. The first is not to display too much running state information of the device, when the operation and maintenance personnel need to know the detailed running state information of the device, the operation and maintenance personnel must use a network management system or a special interface on the portable computer access device to log in the system for checking. The second way to display a large amount of status information is to use a large number of LED status indicators to display the current operating status of the different functional modules, respectively. The third way is to directly use a dedicated display to display the current operating status information of the device.
However, there are significant drawbacks to either approach. The first method requires that the operation and maintenance personnel must use a dedicated interface on the network management system or the portable computer access device and log into the system to check detailed operation status information of the device, which is a very tedious process. In the actual operation and maintenance work of the equipment, the operation and maintenance personnel often need to complete the whole set of operation process only by checking one operation state parameter of the equipment, and the working efficiency is extremely low. The second method uses a large number of LED status indicator lamps to respectively display the operating statuses of different functional modules, which not only has the problem of high design and production costs, but also has the more serious problems that a large number of LED lamps disturb the eyes of the operation and maintenance personnel, the problem positioning is difficult to be completed in a short time, and the consumption of electric quantity by a large number of LEDs is not negligible. The third method has the best use experience, but the cost is very high, which is very unfavorable for the cost control and the large-scale deployment of the product.
Disclosure of Invention

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
An embodiment of the present invention provides a device for displaying an operating state of an apparatus, as shown in fig. 2, including:
a main control chip;
a status indicator light;
the microcontroller is electrically connected between the main control chip and the status indicator lamp and is used for acquiring current running status data of the equipment from the main control chip, modulating the current running status data and driving and controlling the on-off status of the status indicator lamp;
the portable display terminal comprises a display screen for displaying the current operation state data of the equipment, a processor for demodulating visible light signals and a camera for acquiring the visible light signals.
In this embodiment, the status indicator light is an LED, i.e. a light emitting diode, and the on/off status of the status indicator light can be controlled by an output pin of a GPIO port of the microcontroller connected to the status indicator light.
In this embodiment, the main control chip and the status indicator lamp are both originally owned by the device that needs to display the running status, and this embodiment uses a special microcontroller as the driving chip of the status indicator lamp, and taking the power status indicator lamp as an example, the traditional power status indicator lamp is directly connected with the power network, and there is no special driving chip.
Referring to fig. 1 and 2, the method for displaying the operation state of the device includes the following steps:
s1, acquiring current running state data of the equipment from a main control chip of the equipment by using the microcontroller;
s2, the microcontroller modulates the current running state data of the equipment into visible light signals, and the visible light signals are emitted through the state indicator lamps;
s3, the portable display terminal obtains visible light signals through a camera carried by the portable display terminal;
and S4, the portable display terminal demodulates the visible light signal through the processor to obtain the current operation state data of the equipment and displays the data on the display screen of the portable display terminal.
Therefore, the portable display terminal is used outside the equipment needing to display the running state, the camera is aligned to the state indicator lamp of the equipment for shooting, the current running state data of the equipment is demodulated and restored, and then the current running state data are displayed on the display screen, so that operation and maintenance personnel can conveniently and intuitively check the detailed running state of the equipment.
It should be noted that, generally, only one status indicator lamp is needed to achieve the above functions, however, in the actual engineering process, more than one status indicator lamp or a multi-color status indicator lamp may be used to achieve the display of more information or the transmission of a higher-speed modulated signal, without departing from the core idea of the present invention, and also fall into the protection scope of the present invention.
In addition, the method needs to use the visible light communication technology to emit the light modulation signal outwards on the premise of keeping the original basic functions of the status indicator lamp. It is considered that the original brightness of the status indicator lamp is not affected as much as possible while the signal is modulated. Meanwhile, it is also considered that the camera shooting frame rate of the portable display terminal is not generally as high as the sampling rate of an analog-to-digital converter dedicated to the communication device, and the frequency of the modulated optical signal is not too high. In summary, the visible light communication modulation method used in this embodiment is PPM, i.e., pulse position modulation method.
It should be noted that the reason why we use the pulse position modulation method is that the pulse position modulation has better anti-interference capability and higher power utilization rate. However, the pulse position modulation method is not the only choice, and in the actual engineering implementation process, the visible light communication modulation method such as on-off keying modulation (OOK), Digital Pulse Interval Modulation (DPIM), or double-headed pulse interval modulation (DH-PIM) may also be used, which does not depart from the core idea of the present invention and also belongs to the protection scope of the present invention.
In this embodiment, the model of the main control chip is S3C2440, the model of the microcontroller is STM8L101F3P6, and the microcontroller may obtain the operation state data of the device from the main control chip S3C2440 through serial port communication, and then use the pulse position modulation PPM to code and modulate the operation state data of the device and transmit the data.
In this embodiment, the resolution of the camera of the portable display terminal is preferably set to a low level as much as possible, and the color depth is appropriately adjusted to be low so as not to affect the function of detecting the on/off state of the LED. Therefore, the sampling rate of the camera can be improved as much as possible on the premise of not influencing shooting and sampling of the on-off state of the LED, and the reliability of sampling and demodulating results is improved.
In this embodiment, the portable display terminal is dedicated for operation and maintenance personnel, and has an application program, and when the portable display terminal is used, the application program is firstly turned on, and a camera of the portable display terminal is aligned to an LED lamp of the device. At the moment, the application program positions the position of the LED lamp in the shot image through image recognition, judges the current on-off state, continuously records the on-off change process of the LED lamp, finally demodulates and extracts the running state data of the equipment in the on-off state change process of the LED lamp, and then visually displays the data on the display screen of the portable display terminal.
In an alternative embodiment of the present invention, the current operation state data of the device obtained in step S4 is stored in a non-volatile memory of the portable display terminal.
In an optional embodiment of the present invention, the current operation status data of the device obtained in step S4 is reported to the network management system.
In an alternative embodiment of the invention, the portable display terminal is a smartphone.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
