Detailed description of the invention
As shown in Figure 1, the present invention includes ARM microcontroller 1 and takes the supplying cell 2 of each electricity consumption module for power supply in attention device for described elevator safety, and the crystal oscillating circuit module 3 connected with described ARM microcontroller 1, reset circuit module 4, for storing the EEPROM data storage circuitry module 5 of data and the cdma wireless communication module 7 for being sent in Internet network 8 by cdma network 6 by elevator information, the input of described ARM microcontroller 1 is connected to the clock circuit module 9 for taking attention device offer real-time clock signal for described elevator safety, for detecting whether lift car when hoistway door is opened has reached hoistway door place and to the lift car detector of described ARM microcontroller 1 and be used for whether having passenger to stop before detection elevator in real time and exported by the signal detected to the first passive type Infrared Detectors 11 of described ARM microcontroller 1 in real time by the signal real-time Transmission detected in real time, described lift car detector includes being arranged in elevator tunnel just to the photoemitter 12 on the wall of hoistway door and the photelectric receiver 13 being arranged on hoistway door inner surface and for receiving the photosignal that photoemitter 12 occurs, and it is arranged in elevator tunnel just to the second passive type Infrared Detectors 16 on the wall of hoistway door, described photelectric receiver 13 is arranged in same level with described photoemitter 12, described first passive type Infrared Detectors 11 is arranged on the outside top of hoistway door, the outfan of described ARM microcontroller 1 is connected to the voice playing circuit module 14 for playing phonetic warning signal and the LED flash 15 for the alarm signal that flashes when lift car is also less than but hoistway door is opened, and described LED flash 15 is arranged on hoistway door outer surface.
In the present embodiment, described ARM microcontroller 1 is ARM microcontroller chip LPC2312. Described EEPROM data storage circuitry module 5 is mainly made up of chip 24C512. Described clock circuit module 9 is mainly made up of chip DS1302. Described first passive type Infrared Detectors 11 is Japan's Ai Lifu HP-U-15C ceiling series Passive Infrared Detector. Described voice playing circuit module 14 is mainly made up of speech chip ISD1420. Described LED flash 15 is red LEDs flash lamp.
The work process of the present invention is: whether the first passive type Infrared Detectors 11 has passenger to stop before detecting elevator in real time and exported in real time by the signal detected to described ARM microcontroller 1, when not having passenger to rest on before elevator, the first passive type Infrared Detectors 11 output low level; When there being passenger to rest on before elevator, the first passive type Infrared Detectors 11 exports high level; When ARM microcontroller 1 receive the first passive type Infrared Detectors 11 export high level time, ARM microcontroller 1 starts to receive the signal of photelectric receiver 13 output; When lift car does not arrive hoistway door place, the transmission of photosignal and infrared signal is not blocked due to lift car, photelectric receiver 13 is able to receive that the photosignal that photoemitter 12 is launched, photelectric receiver 13 is output as high level, and second passive type Infrared Detectors 16 can sense elevator before have passenger to stop, the second passive type Infrared Detectors 16 is output as high level; When lift car arrives hoistway door place, owing to lift car has blocked the transmission of photosignal and infrared signal, photelectric receiver 13 is no longer able to receive the photosignal that photoemitter 12 is launched, photelectric receiver 13 is output as low level, and second passive type Infrared Detectors 16 be no longer able to sense elevator before have passenger to stop, the second passive type Infrared Detectors 16 is output as low level; When the output of photelectric receiver 13 is transformed to low level by high level and the second passive type Infrared Detectors 16 is output as high level, illustrate that hoistway door has been opened and lift car does not arrive hoistway door place, now, ARM microcontroller 1 controls voice playing circuit module 14 and plays phonetic warning signal, simultaneously, ARM microcontroller 1 controls LED flash 15 and flashes alarm signal, and reminding passengers lift car is also less than but hoistway door is opened, and reminding passengers arouses attention; When the output of photelectric receiver 13 is transformed to low level by high level and the second passive type Infrared Detectors 16 is output as low level, illustrate that hoistway door has been opened and lift car has arrived hoistway door place, now, ARM microcontroller 1 controls voice playing circuit module 14 and plays voice message signal, prompt passengers takes safely elevator, in all the other situations, voice playing circuit module 14 does not send voice message signal, and LED flash 15 is not glittering yet.
The above; it it is only presently preferred embodiments of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure change above example made according to the technology of the present invention essence, all still fall within the protection domain of technical solution of the present invention.
