Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention based on the equipment monitoring system of visible light communication;
Fig. 2 is the apparatus monitoring method process flow diagram of the embodiment of the present invention based on visible light communication.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, based on the equipment monitoring system of visible light communication, comprise a monitoring equipment and multiple stage equipment to be monitored, every platform equipment to be monitored at least has a LED, the position of each LED is fixed, represent different information by glow color and flicker frequency, react the state of its place equipment to be monitored, glow color, the flicker frequency of LED can also by coding-control to carry data message.Monitoring equipment is fixedly installed relative to the position of equipment to be monitored and angle, and monitoring equipment comprises imaging lens, imageing sensor, image processing hardware.Imaging lens is for taking the LED on equipment to be monitored, because monitoring equipment can take the luminance (glow color and flicker frequency) recording LED on all equipment to be monitored, between the LED of therefore imaging lens and all equipment to be monitored, all dull thread blocks.Imageing sensor is used for the picture imaging of being taken by imaging lens, and image processing hardware identifies the information that LED represents according to the position of LED, glow color, flicker frequency, and then obtains the state of its place equipment to be monitored; Preferably, imageing sensor is high frame speed imageing sensor, and except the LED flicker for receiving common frequencies, the LED flicker being greater than 50Hz high frequency of usual naked eyes None-identified, also can be received by high frame speed imageing sensor.
As shown in Figure 2, the present invention is based on the apparatus monitoring method of visible light communication, specifically comprise the steps:
S1. determine position and the angle of the relatively all equipment to be monitored of monitoring equipment, and keep monitoring equipment to be fixedly installed, guarantee that the pixel position of all LED imaging is on the image sensor fixed; Ensure that between imaging lens and the LED of all equipment to be monitored, all dull thread blocks, and can photograph all LED; The position setting up the pixel on the image sensor of LED on equipment to be monitored maps, and is convenient to image recognition processing.
S2. the Monitoring Rules of LED is defined, the i.e. glow color of LED and the information representated by flicker, for showing the state of the equipment to be monitored at LED place, its flicker or glow color change the Monitoring Rules following agreement, such as, definition Level 1Alarming is: LED glows, and alternately lights extinguishing, lights and extinguish all to continue 0.5 second.Monitoring equipment obtains described Monitoring Rules simultaneously, and in addition, monitoring equipment also gets the size and shape of each LED.
S3. imaging lens takes all LED, and imaging on the image sensor, image processing hardware maps according to the position of LED on imageing sensor, distinguishes different LED, and obtains the information represented by different LED luminance (glow color and flicker frequency) according to described Monitoring Rules.Such as, the Devices to test that certain pixel of imageing sensor is corresponding, the LED of its power supply is yellow or green, according to color, image processing hardware can judge that this Devices to test is in standby or normally works.For another example, imaging lens photographs the flicker in certain LED period, LED can be judged as 01 Bit data with or without luminescence, and image processing hardware, again according to Monitoring Rules, carries out information decoding, receives the state of its place Devices to test that this LED transmits.Further, image processing hardware, by the position of each LED pixel on the image sensor, obtains shape corresponding to this LED and size, and then understands these LED details in more detail.Usually the high frequency LED flicker naked eyes being greater than 50Hz cannot be discovered, but can be received by high frame speed imageing sensor, and according to sampling principle, transferable maximum information speed is the half of imageing sensor frame speed.
S4. the information parsed is focused on by webmaster.
