Deaf safety emergency alarms of the design and development
Point, vibration sense and auditory sense parallel. Compensation for hearing defects through vibration sense with ~ given advantage. Vibration sense of the device through the full range of compensation hearing defect is a new attempt. The sense of vibration is a close feeling, mainly by contact with perception, vibration sensation sensitivity is very low. Therefore, the vibration sense the transmission of information more difficult and complex. The bed is vibrating alarm felt by the media. Vibration information to ensure effective communication to the deaf. Alert the deaf to sleep. 3.2 The multiplication principle that each of the alarms alert deaf people to be more than 90% probability. An independent look at the theory of efficient standard is not high. However, its actual efficiency is very high. The probability of a person is not alert is A = 0.10. Each person is not alert is an independent event, in line with the principle of multiplication probability conditions. Chuang quarters by a calculation of 4 people, 4 people are not vigilant is the probability of all: P: AAAA = 0.0001 each dormitory to be vigilant as long as a person, shaking about other people's beds, the dormitory can be quickly and safely escape. Therefore, the 4 quarters by 99.99% probability of awakening. If it is 6 quarters, to be effective up to 99.9999% probability of awakening. Some quarters in the absence reduced to 3 people, the hostel is still as high as the probability of awakening was 99.9%, the safety factor is still quite high. When the downsizing of some quarters to 1-2 people, places special attention should be given the value of room, the safe and efficient emergency alert device reduced to 99.9% less. Is not reliable state. 4. 4.1 The basic structure of the main body of the utility model alarms including the control rope, hit the hammer, vertical sleeve. Sleeve top with pulleys and ropes, rope and pulley rolling phase control, the control rope and sling phase between the control rod, control rod has a hook. Linked to the control rod hook for the ramp, hit the hammer with rings, hooks and rings live connection, the sleeve with the bottom bracket, the lower part with holes. The device linked to a special section of the hook curve. Rather than traditional circular hook. Conducive to hit the hammer off. Linked in a non-center lever, helps to reduce the control of the pull cable guide. 4.2 The structure of the control panel control panel from the bottom, bearing, bolt composition. Cord wrapped around the master guide bearings, usually by the bolt lock bearings, master guide cable tension. Emergency, pull out the pin, bearing free to rotate in the gravity hammer, bearing out from the master guide rope, in a relaxed state. Each dormitory building install two control panel, the value of a room in the hostel, one in the outdoor (as with other fire equipment management). As long as a control panel to play a role in firing the entire unit can alarm. The utility model provides a simple, safe and convenient for the Deaf security emergency alert device. Its effect is: This utility model the sleeve fixed in Chuangban Shang, usually control the rope is in tension, it will be hit by hammer lever lift, when an emergency occurs, loosen the control panel latch, sub-controlled pilot cable , master guide rope in a relaxed state, in the gravity hammer, lever one end of the sink, around the non-active end of the lever clockwise, when the hook (curve section of the hook) to open slightly lower than the horizontal position of 15 , separation of rings and hooks, heavy hammer fall off, hit the bed board in free mode. Vibration caused by the bed board, an alarm function. The alarm structure is simple, easy to operate, safe to use. 4.3 Master Control Transmission lead rope to the floor structure (each row of bungalows quarters),[link widoczny dla zalogowanych], the control of a housing complex, a master control panel can control multiple cable guide. Sub-master control guide rope and pull rings connected by a cable guide, each sub-claim control of a controlled pilot quarters. Ring-pull cable connected to avoid sub-controlled pilot generated tension balance, to ensure control of transmission to each dorm, beds, firing each vibrator. Most developed countries can provide many people with disabilities professional, high standard equipment items, but not ideal for the Deaf and the safety of emergency warning device, the alarm is applying for international patents. 【
