Summary of the invention
The purpose of this utility model is to provide a kind of and can in time reports to the police by the number density of going downstairs, the people front of informing the back is crowded, so that the people of back in time stops or slowing down downstairs, can effectively prevent the biological and ecological methods to prevent plant disease, pests, and erosion tread event stair pedestrian of the primary school countdown warning device that tread event takes place.
For reaching above purpose, the technical scheme that the utility model adopted is: the biological and ecological methods to prevent plant disease, pests, and erosion tread event stair pedestrian of this primary school countdown warning device, bar shaped box and infrared module and infrared ray receiver module by ultrared bar shaped box of emission and receiving infrared-ray, alarm constitutes, the infrared module is installed in the inboard of the ultrared bar shaped box of emission, the infrared ray receiver module is installed in the bar shaped box and the relative side of the ultrared bar shaped box of emission of receiving infrared-ray, alarm is installed in the ultrared bar shaped box of emission middle part, it is characterized in that: described infrared module is established 8-12, distance between the adjacent infrared module is 20cm, is connected with circuit board after the parallel connection of infrared module; Simultaneously, described infrared ray receiver module is also established 8-12, and the distance between the adjacent infrared ray receiver module is 20cm also, and it is long to make light beam arrange 1.5-3m, is connected with corresponding circuit board after the parallel connection of infrared ray receiver module.
When using the utility model, the ultrared bar shaped box of emission is fixed on the railing of stair, also can be made as an integral body, the bar shaped box of receiving infrared-ray is installed on the body of wall of a side relative with launching ultrared bar shaped box with railing.
The utility model is also implemented by following measure: the length of the bar shaped box of ultrared bar shaped box of described emission and receiving infrared-ray is 1.5-3m; The voice module of described alarm for finishing in advance, as the voice suggestion of sending " this section is crowded, and the people of back slowly down "; The circuit of described infrared module and infrared ray receiver module comprises transformer T, commutation diode VD 1-VD 4Three-terminal voltage-stabilizing ic chip 4 grades partly constitute, infrared module and infrared ray receiver module are established 8-12, and it is in parallel, output 12V stable DC voltage is for the entire circuit electricity consumption, IC1 is the infrared module, inner by the power management device, password IC, compositions such as infrared modulation circuit and middle power infrared transmitting tube, module dead ahead, energising back lens aperture is promptly outwards launched the row's Infrared through the password modulation, IC2 is that supporting infrared ray is accepted module, when people's current density can not all be blocked row's infrared light rays, IC2 receives a branch of infrared light rays of IC1 emission at least, the triode of output terminal OUT inside modules ends, be high level, the monostable circuit that be made up of time base circuit IC3 this moment is in reset mode, 3. pin no-output, solenoid valve is not worked, when people's current density shelters from row's infrared light rays, IC2 can not receive the Infrared instruction, the inner triode conducting of OUT end, be IC3 trigger end 2. pin be subjected to low level and trigger, monostable circuit overturns immediately and enters SM set mode, 3. pin is exported high level, the VT conducting, solenoid valve is opened, and connects alarm, carry out the audio alert prompting, the 12V positive supply charges to C4 by R2, and behind T=1.1R2 * C4 ≈ 2min, threshold value end 6. pin electrical level rising arrives 2/3V approximately DDThe time, IC3 resets, 3. pin output low level, and circuit just is returned to original stationary state; This circuit is a known technology, only in parallel a plurality of infrared modules and infrared ray receiver module.
The beneficial effects of the utility model are: owing to increased the device of reporting to the police by people's current density on stair, when the people who goes downstairs is too crowded, can report to the police immediately, the people of prompting back is slowly down, the generation of pupil's tread event can be effectively prevented, middle and primary schools can be widely used in.
