Embodiment 2

[0162] 1 to 6, in the wireless video transmission of this embodiment, a video capture chip for video information, a video compression chip for wavelet video compression, a real-time calculation of quantization parameters for each field of images, and completion Some important algorithmic DSP chips, high-complexity programmable logic devices (CPLD) for logic control of video capture chips and DSP chips, and communication serial ports for wireless communication. After the collected digital video is compressed by the video compression chip, The DSP is used to package, and then the compressed video data is sent by the wireless transceiver module. The wireless transceiver module conforms to the IEEE802.11b communication standard.

[0163] The rest of the structure and working process are the same as in Embodiment 1.

[0164] The invention effect produced by the above-mentioned embodiments 1 and 2 is to make full use of the increasingly mature wireless video communication calculation, e...

Description

(1) Technical field [0001] The invention relates to an elevator safety guard device based on image recognition technology. (2) Background technology [0002] As the buildings in cities are built higher and higher, the use of elevators is becoming more and more common, and the issue of elevator safety has attracted increasing attention. On the one hand, there are more and more elevators. At present, the number of elevators in my country has reached 140,000, and it is still increasing at a rate of more than 15% per year. If it is to reach the level of developed countries in the world, the number of elevators will reach 1.4 million. Around the stage. On the other hand, there are more and more elevators working with illnesses and elevators lacking maintenance. Due to the high frequency of use of elevators in my country, the lack of normal maintenance all the year round, sick work, the quality of some elevator accessories, etc., the safety of elevators Hidden hazards are also becoming...
