Embodiment 2

[0184] The rest is the same as Embodiment 1, the difference is wireless video transmission. In this embodiment, a video capture chip for video information, a video compression chip for wavelet video compression, and a real-time calculation of quantization parameters for each field of image are used. And the DSP chip that completes some important algorithms, the high-complexity programmable logic device (CPLD) for logical control of the video capture chip and DSP chip, the communication serial port for wireless communication, and the collected digital video is compressed by the video compression chip After that, the DSP packs the compressed video data, and then the wireless transceiver module sends the compressed video data. The wireless transceiver module conforms to the IEEE802.11b communication standard.

[0185]The above-mentioned embodiments 1 and 2 have the effect of making full use of the increasingly mature technologies of wireless video communication computing, embedded sy...

Abstract

The invention discloses an elevator inner-brute force device based on image and voice recognizing technology, which comprises the following parts: video sensor, voice receiver and monitor central computer to monitor elevator, wherein the video sensor and voice receiver connects monitor center computer through wireless network equipment, which contains display mode to display real-time elevator video data, the video sensor connects monitor central computer through wireless network exchanging equipment, which is warless LAN center, the computer contains microprocessor with image reading mode, image variation calculating mode, connecting area calculating mode, judging mode in the elevator to judge whether the accident occurs.

Description

(1) Technical field [0001] The invention relates to an anti-violence device in an elevator based on image and voice 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. After the elevator brings convenience and speed to human life, it also challenges human safety. Due to the relatively closed nature of the elevator, it also poses a threat to human safety. In the narrow space of the elevator, people's constraints on themselves will also be reduced to the lowest point. News media often report some elevator violence incidents. In addition to property losses, victims have suffered a lot of physical and psychological trauma after experiencing elevator violence. The types of elevator violence incidents can be divided into the robbing of money and color in the elevator. And other violent incidents. [00...
