Abstract
The utility model discloses a key place self-help alarm telephone system. The system is characterized in that the system comprises a relay and an alarm; on one hand, the relay is connected with a telephone through a silicon controlled rectifier; and on the other hand, the relay is connected with the alarm. According to the utility model, an internal small telephone is used to automatically start the alarm; once an accident occurs, no matter in what position, a user simply dials the corresponding telephone numbers (such as 119), and an immediate alarm is realized; the system is simple, quick and prompt; relevant staff hear the alarm and immediately dial 119 to call the police or take relevant contingency plans; in a word, the time for the system to start the alarm is shortened to below 1min from 3min; and the ability of accident control is improved.
Description
Technical field
The utility model relates to the self-saving and alarming device, specifically a kind of crucial place self-saving and alarming telephone system.
Background technology
At present, the inflammable and explosive places such as chemical plant, oil plant all are provided with alarm device, if when finding the condition of a fire or Leakage Gas, the device of all can sounding the alarm is warned.Be contained in the fire-fighting chamber at Dongying compressor station alarm, when dangerous situation is arranged, must go to the fire-fighting chamber by the operator on duty, sound the alarm again.And the storehouse, lighter hydrocarbons station as the Dongying compressor station so does not allow to be with mobile phone to enter the production area, if the operator on duty is not at night shift room, when finding dangerous situation, can't be in time and the operator on duty contact, and certain distance is arranged between dangerous situation post and the fire-fighting chamber, can not reach alarm establishment officer and speedily carry out rescue work, miss an opportunity because of a delay, cause unnecessary loss.
In the situation that there is not mobile phone, all by intramural small size phone, this device is exactly on this basis to the contact between the post, and a certain phone is carried out improved technology.
Summary of the invention
The purpose of this utility model is to provide crucial place self-saving and alarming telephone system, automatically fires siren by the small size phone in inside, in case dangerous situation occurs, as long as no matter dial corresponding telephone number in that post.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, and crucial place self-saving and alarming telephone system comprises relay, and described relay is connected with telephone set by silicon controlled rectifier.
Also comprise alarm, described relay is connected with alarm.
The used power supply of described relay is directly used the 12V DC power supply.
The used power supply of described relay becomes interchange 12V power supply from miniature transformer with 220V voltage, and relay drives the control alarm.
The used power supply of described relay becomes direct current 12V power supply from miniature transformer after with the 220V voltage commutation, and relay drives the control alarm.
Compared to prior art, the utlity model has following beneficial effect:
The utility model is fired siren automatically by the small size phone in inside, in case dangerous situation occurs, as long as no matter dial corresponding telephone number (such as 119 etc.) in that post, at once reports to the police, and simple and fast, in time rapidly.The related personnel hears and at once dials the police emergency number 119 or take relevant emergency preplan after the alarm.In a word, sound the alarm time of device of the utility model is shortened to below the 1min by 3min, improves the accident control ability.
Description of drawings
Fig. 1 is crucial place of the present utility model self-saving and alarming telephone system structural representation.
Embodiment
Relevant detailed description of the present utility model and technology contents cooperate description of drawings as follows, yet accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
With reference to accompanying drawing 1, crucial place self-saving and alarming telephone system is characterized in that, comprises relay, alarm, and described relay is connected with telephone set by silicon controlled rectifier on the one hand, is connected with alarm on the other hand.
This device is connected phone with alarm, utilize the voltage of the ring of telephone set loop output own, and the conducting bidirectional thyristor is connected auxiliary relay kA and driven warning system.And the voltage of the ringing system output of telephone set own is as triggering signal, drives controlled silicon conducting.Miniature transformer becomes direct current 12V after 220V voltage is become interchange 12V or rectification, controls warning system as the auxiliary relay driving power.Power unit can directly be used 12V DC power supply, KA(relay) can drive the warning devices such as siren, sound equipment.
The above only is preferred embodiment of the present utility model, and non-in order to limit claim of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to claim of the present utility model.
