Description
Technical field
The present invention relates to elevator protection technology field, specifically a kind of used during elevator falling protective device.
Background technique
With the development of real estate and the progress of science and technology, high building more than present 6 floor is more and more, especially more than 20
Layer, the high building of 30 multilayers is very common in city, and according to national regulation, building is more than that 6 floors just need to install elevator, because
This, these high buildings are mounted on elevator, but since floor is higher, once phenomenon of falling occurs in elevator, the people in elevator is basic
On without raw it is also possible that surviving by sheer good luck in time, it is also possible to become maimed person or plant person, then how to guarantee that elevator is being fallen
Guarantee the life security of people in elevator, the technical issues of becoming current urgent need to resolve when building phenomenon.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of used during elevator falling protective devices, can be in elevator
When falling, the people in elevator is preferably protected, is not in personal injury.
To achieve the goals above, the present invention provides a kind of used during elevator falling protective device, including is mounted on elevator hoist dress
The speed probe on machine shaft is set, for acquiring motor speed signal, the velocity sensor being mounted on elevator is used for
Speed signal when elevator operation is acquired, the folding air cushion being mounted in elevator is mounted on the baroceptor folded in air cushion,
For acquiring the air pressure signal folded in air cushion, and the electric aeration device being connected with air cushion inflation mouth, it is mounted in elevator
The single-chip microcontroller in portion judges whether to start electric gas-filled for receiving tach signal and speed signal, and according to the signal received
Device judges whether to stop electric aeration device for receiving air pressure signal, and according to the signal received；Inside single-chip microcontroller
It is preset with range of speeds value, velocity interval value, air pressure range value.
Further, including starting/stop button for starting or stoping electric aeration device, the starting/stop button
It is connected by conducting wire with electric aeration device.
Further, each side wall of elevator interior is mounted on folding air cushion, and each air cushion connects an electric aeration device.
Preferably, single-chip microcontroller model AT89C51.
Compared with prior art, single-chip microcontroller of the present invention controls electronic fill according to the tach signal and speed signal received
Whether device of air is inflated, and when tach signal or speed signal be not in the value range of single-chip microcontroller inner setting, single-chip microcontroller can be controlled
Electric aeration device work is inflated to air cushion is folded, and further according to the atmospheric pressure value of baroceptor acquisition, is controlled electric gas-filled
Device stops working, such elevator fall land when, since all side walls of elevator have an air-cushion protection, people and elevator are not
It will appear hard contact, be effectively protected the life of people in elevator.
Detailed description of the invention
Fig. 1 is invention's principle block diagram.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
9 diameter of the present embodiment top plate presplit blasting hole is 89mm, hole depth 35m.
As shown in Figure 1, a kind of used during elevator falling protective device of the present invention, including it is mounted on machine shaft in elevator lifting device
On speed probe, for acquiring motor speed signal, the velocity sensor being mounted on elevator, for acquire elevator operation
When speed signal, the folding air cushion being mounted in elevator, be mounted on fold air cushion in baroceptor, for acquire fold
Air pressure signal in air cushion, and the electric aeration device being connected with air cushion inflation mouth, are mounted on the single-chip microcontroller of elevator interior, type
Number judge whether to start electronic fill for receiving tach signal and speed signal, and according to the signal received for AT89C51
Device of air judges whether to stop electric aeration device for receiving air pressure signal, and according to the signal received；In single-chip microcontroller
Portion is preset with range of speeds value, velocity interval value, air pressure range value.
It to prevent single-chip microcontroller from occurring accident suddenly, cannot use, say that wireless signal is unstable, be arranged one in elevator and open
Dynamic/stop button, is electrically connected, for starting or stoping electric aeration device with electric aeration device by conducting wire.
In order to preferably protect the people in elevator, folding air cushion, each air cushion are mounted in each side wall of elevator interior
Connect an electric aeration device.
When work, the tach signal of speed probe motor in real time shaft, and monolithic is sent to by wireless signal
Machine, velocity sensor acquires the rising of elevator or the speed signal of whereabouts in real time, and is sent to monolithic, air pressure by wireless signal
Sensor acquires the air pressure signal of air cushion in real time, and is sent to single-chip microcontroller, the revolving speed that single-chip microcontroller will receive by wireless signal
Signal and speed signal are compared with range of speeds value preset inside single-chip microcontroller and velocity interval value respectively, and judgement is
It is no within the set range, if do not existed, then control electric aeration device work, air cushion is inflated, at this point, single-chip microcontroller connects in real time
Atmospheric pressure value is received, and is compared with internal preset air pressure range value, the atmospheric pressure value such as received is not in the range of setting
In value, then controls electric aeration device and stop to air cushion inflation.
If phenomenon of falling occurs in elevator, but electric aeration device is not activated, and the people in elevator can pass through installation
It is started or stoped in starting/stop button control electric aeration device of elevator interior, to be inflated or stop to air cushion
Inflation.
The present invention again used during elevator falling when, provide automatically and manually duplicate protection, preferably the people in protection elevator.
