Description
Technical field
The present invention relates to a kind of sensor, and in particular to has the obstacle avoidance sensor of very fast response speed.
Background technology
With the development of science and technology, the popularization of electric automatization, door and window is also more and more intelligent, such as can the work of automatic detection human body
Dynamic, automatic opening and closing door etc., in above door and window activity, anti-pinch obstacle avoidance sensor is essential.In the prior art typically using red
Outside line sensor senses physical activity information, to control door and window to close or open, avoids injury accident between door and window and people
Occur.But infrared sensor volume is generally large, and induction precision is relatively low, it is desirable to distance it is very near, directionality is poor so that
It is poor as the automatically-controlled door security performance of anti-pinch obstacle avoidance sensor using infrared sensor, accident is hit by double-layered quilt and still sent out repeatedly
It is raw.
In addition, infrared anti-collision sensor detection zone of the prior art is very limited, can only on the door or window some position
Put and detected, practicality is poor.
The content of the invention
It is an object of the invention to overcome above technical problem, there is provided there is the obstacle avoidance sensor of very fast response speed, it is real
Show wide a kind of induction precision height, detection range, compact, strong antijamming capability, be easy to charge, can effectively prevent anti-pinch anticollision
The purpose for the anticollision induction device that accident occurs.
The present invention is achieved through the following technical solutions：
Obstacle avoidance sensor with very fast response speed, including fan-shaped control panel, be provided with the fan-shaped control panel by
The sensor array of multiple flight time measurement unit compositions, arc-shaped side of multiple flight time measurement units along fan-shaped control panel
Set at equal intervals, the launch point and pip of each flight time measurement unit are vertical with arc-shaped side, on fan-shaped control panel
It is additionally provided with processor, rechargable power supplies module, input and output connector, USB interface, the flight time measurement unit, can
Charging power modules, input and output connector are connected with processor respectively, and the USB interface is connected with rechargable power supplies module,
Wherein：
Flight time measurement unit：Transmitting laser rays simultaneously receives reflection laser, and will transmitting laser intelligence and reflection laser
Information transfer is to processor；
Processor：Receive the transmitting laser intelligence and reflection laser information of flight time measurement unit transmission, when laser from
When being transmitted into the flight time exception of transmitting, abnormal signal is sent to input and output connector；
Input and output connector：The abnormal signal that reception processing device is sent, and export.Further, for above technology
Problem, the present invention devises a kind of new anticollision induction device, first using the biography of multiple flight time measurement units composition
Sensor array, the sensor array is formed forms arcwall face around fan-shaped control panel, when by fan-shaped control panel side mounted on a door
An angle when, adhered shape of the fan-shaped control panel just with rectangular door, the sensor array of arc-shaped side detects in dispersion shape, can
The scope of whole door is all covered, compared with prior art, substantially increases anticollision detection range；Secondly, then by sensor array
Arrange and be similarly disposed at processor, the input and output connector connection composition anticollision induction system on bar shaped control panel.During flight
Between measuring unit be existing in the market usual products, using laser sensor, compared to existing infrared sensor composition
Anticollision induction device volume is smaller, and precision is higher, and antijamming capability is stronger.Specific anticollision principle is as follows：Bar shaped control panel is pacified
On door or window, flight time measurement unit sends laser rays and receives reflection laser inside sensor array, processor meter
The distance for answering object to sensor can be obtained from the flight time for being issued to return by calculating the laser of unit, thus be calculated in face
(i.e. door leaf) has nobody or object in scanning sensor detection zone, and non-faulting reason causes some or multiple flight time measurements
The laser turnaround time that unit is sent shortens, then illustrates someone or other objects in detection zone.Then processor controls
(high level is that induction region has object to sensor states signal in input and output connector, and low level does not have for induction region
Object) output.Using the equipment of sensor, i.e., the equipment being connected with input and output connector, as switching door actuator receives
Corresponding action can be taken after signal, stops closing the door, the purpose for avoiding anticollision anti-pinch accident from occurring is reached with this.Finally, originally
Invention uses rechargable power supplies module to be powered for the circuit structure of the present invention, and USB interface, Ren Mentong are set on fan-shaped control panel
Data wire is crossed to can be achieved to the convenient charging of power module of the invention.
The flight time measurement unit is connected with processor by CAN.High reliability that CAN has and good
Processor is connected by good error detection capability, the present invention using CAN with all flight time measurement units, so not
Can only centralized management be carried out to flight time measurement unit, the jamproof ability of the present invention can be more improved, even in evil
Also the stability of communication can be kept in bad environment.
The back side of the fan-shaped control panel is additionally provided with adhesive-layer.Further, can be by sector by the setting of adhesive-layer
Control panel is easily bonded on door and window, and without destroying door body or window structure, more with practicality.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention has the obstacle avoidance sensor of very fast response speed, induction precision is high, detection range is wide, compact,
Strong antijamming capability, it is easy to charge, can effectively prevents anti-pinch anticollision accident from occurring；
2nd, the present invention has the obstacle avoidance sensor of very fast response speed, and communication is stable stronger, and the setting of adhesive-layer to pacify
Dress is more convenient, and without destroying door body or window structure, more with practicality.
