Abstract
The utility model discloses an elevator car safety running system and belongs to the technical field of elevator car safety. The elevator car safety running system comprises an elevator car running control unit for switching an elevator car running state, a central processing unit for controlling the elevator car running control unit, an audio decibelmeter for detecting audio strength in an elevator car and a comparator which can compare the audio strength detected by the audio decibelmeter with a preset standard value and send electric signals to the central processing unit after judgment. The audio decibelmeter is in signal connection with the comparator, the comparator is in signal connection with the central processing unit, and the central processing unit is in signal connection with the elevator car running control unit. The elevator car safety running system solves the elevator car safety running technical problems, and the elevator car with the running system can automatically stop running when passengers in the elevator car shout in case of urgent or dangerous conditions.
Description
Technical field
The utility model relates to a kind of lift car safe operation system in a kind of lift car safety method field.
Background technology
As everyone knows, elevator has become a part for people's modern life, and lift car safety work has been directly connected to people's the security of the lives and property.
At present, existing elevator cage operation system often can be with safety function modules such as lift car overload protection and lift car speed-limiting protections.But in the time that people use lift car, run under urgent or dangerous situation, for example, when certain parts of people hand or health are clipped to by elevator cab door or elevator door, above-mentioned safety function module just cannot play the effect of guarantee people life security.
Utility model content
The purpose of this utility model is to provide a kind of passenger in lift car to occur promptly or lift car safe operation system that can be automatically out of service under dangerous situation in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the lift car safe operation system that the utility model is designed, comprises
One for switching the elevator cage operation control unit of elevator cage operation state;
One for controlling the central processing unit of elevator cage operation control unit;
An audio frequency decibel instrument for detection of audio frequency intensity in lift car;
And the audio frequency intensity that audio frequency decibel instrument can be detected presets standard value and compare with it, through judgement, send the comparator of electric signal to central processing unit;
Audio frequency decibel instrument in above-mentioned is connected with comparator signal, and above-mentioned comparator is connected with central processing unit signal again simultaneously, and central processing unit is connected with elevator cage operation control unit signal again.
Decibel instrument in above-mentioned is the most basic noise-measuring instrument, is a kind of existing conventional products, and those skilled in the art all can directly obtain by purchase, therefore applicant seldom describes in detail to above-mentioned decibel instrument at this.
The above-mentioned lift car safe operation system of one that the utility model provides, when work, step is as follows, and first audio frequency decibel instrument detects audio frequency intensity in lift car; Then the scream audio frequency intensity section of sending when user is subject to danger by comparator is redefined for standard value, and the audio frequency intensity that audio frequency decibel instrument is detected and above-mentioned standard value are made comparisons, and through judgement, sends electric signal to central processing unit; The electric signal control elevator cage operation control unit that last central processing unit is sent according to reception comparator.
Report to the police in order also to realize when central process unit sends instruction out of service by elevator cage operation control unit to lift car voluntarily, above-mentioned central processing unit also signal is connected with annunciator; Thereby simultaneously in order to switch it and to send to the electric signal of elevator cage operation control unit by central processing unit being carried out to hand reset, thereby change fast the running state of lift car, above-mentioned central processing unit also signal is connected with interrupt switch.
The physiology principle that the utility model can be shouted loudly in the time being in urgent or dangerous situation naturally according to people, can be by detecting audio frequency intensity in car thereby designed one, compare presetting standard value in detected audio frequency intensity and comparator again, through judgement, be in comparator when predefined audio standard value section in definite above-mentioned audio frequency intensity, thereby make by central process unit the lift car safe operation system that operating lift car moment stops, above-mentioned operational system effectively reduces the lift car system potential safety hazard that exists in service, the security of the lives and property of passenger can be ensured to some extent.Also have center processing unit that the utility model provides also signal connected annunciator, such as buzzer phone, central process unit is reported to the police when control lift car is out of service, last above-mentioned central process unit also signal is connected with interrupt switch, think it is elevator ride personnel during in urgent or dangerous situation by mistake when elevator ride personnel's the system of shining into of laughing and frolick, elevator ride personnel can restart elevator cage operation voluntarily by central process unit.
Brief description of the drawings
Fig. 1 is the schematic diagram of the embodiment 1 lift car safe operation system that provides;
Fig. 2 is the schematic diagram of the embodiment 2 lift car safe operation system that provides.
In figure: central processing unit 1, elevator cage operation control unit 2, decibel instrument 3, comparator 4, annunciator 5, interrupt switch 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1, the lift car safe operation system that the present embodiment provides, comprises
One for switching the elevator cage operation control unit 2 of elevator cage operation state;
One for controlling the central processing unit 1 of elevator cage operation control unit 2;
An audio frequency decibel instrument 3 for detection of audio frequency intensity in lift car;
And the audio frequency intensity that audio frequency decibel instrument 3 can be detected presets standard value and compare with it, through judgement, send the comparator 4 of electric signal to central processing unit 1;
Audio frequency decibel instrument 3 in above-mentioned is connected with comparator 4 signals, and above-mentioned comparator 4 is connected with central processing unit 1 signal again simultaneously, and central processing unit 1 is connected with elevator cage operation control unit 2 signals again.The step of the present embodiment in the time of operation is as follows:
First audio frequency decibel instrument 3 detects audio frequency intensity in lift car; Then the scream audio frequency intensity section of sending when user is subject to danger by comparator 4 is redefined for standard value, and the audio frequency intensity that audio frequency decibel instrument 3 is detected and above-mentioned standard value are made comparisons, and through judgement, sends electric signal to central processing unit 1; The electric signal control elevator cage operation control unit 2 that last central processing unit 1 is sent according to reception comparator 4.
Embodiment 2:
The lift car safe operation system that the present embodiment provides, its general structure is consistent with embodiment 1, as shown in Figure 2, but report to the police in order also to realize when central process unit sends instruction out of service by elevator cage operation control unit 2 to lift car voluntarily, above-mentioned central processing unit 1 is gone back signal and is connected with annunciator 5; Thereby simultaneously in order to switch it and send to by central processing unit 1 being carried out to hand reset the electric signal of elevator cage operation control unit 2, thereby change fast the running state of lift car, above-mentioned central processing unit 1 signal connection is gone back signal and is connected with interrupt switch 6.
