The utility model relates to an anti-pinch safety device for children's fingers. The input end of the single-chip microcomputer is connected; the output end of the single-chip microcomputer is connected to the electromagnetic clutch; the electromagnetic clutch controls the opening or closing of the door body. The utility model judges whether there is an object (finger) at the door seam by detecting the infrared opposite radiation state, and controls the opening and closing state of the door to protect the safety of children.
Description
Technical field
The utility model relates to single-chip microcontroller and automatic measurement technique and intelligent control technology, especially a kind of children's finger is anti-
Press from both sides safety device.
Background technique
The case that infants and children's finger is crushed by crack between a door and its frame in recent years is more and more, although having safety door plug, safety door card
A degree of protection can be played, but its mechanism is simple, does not have automation detection and control function, reaction is not quick enough, and does not have
Intelligent control, can not achieve to the finger of children whether at crack between a door and its frame intelligent measurement, the switch state of door can not be controlled.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of children's finger clamp-proof safety device.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of children's finger clamp-proof safety device,
Infrared sensor, single-chip microcontroller and electromagnetic clutch including door body crack between a door and its frame side is arranged in；The infrared sensor is set respectively
It sets in the top and bottom of door body；The input terminal of the output end connection single-chip microcontroller of infrared sensor；The output end of the single-chip microcontroller
Connect electromagnetic clutch；The electromagnetic clutch control door body opens or closes.
Further, single-chip microcontroller described in the utility model is AT89C52 single-chip microcontroller.
It further says, single-chip microcontroller described in the utility model is also connected with buzzer, indicator light and wireless remote control
Module.
Using AT89C52 single-chip microcontroller as the intelligent controller of core, single-chip microcontroller acquires the signal of photoelectric beam detector at crack between a door and its frame, sentences
Whether not current infrared emission is blocked by object (finger), if it has not, then door normally opens and closes, if any, then controller issues signal,
The state for locking door, prevents finger from being pressed from both sides.
The utility model has the beneficial effects that solving defect present in background technique, by detecting infrared emission shape
State judges whether there be object (finger) at crack between a door and its frame, and controls the switch state of door, protects children's safety.Advantage and effect: (1)
The control of 89C51 single-chip microcontroller, at low cost, response is fast, high reliablity；(2) original structure is varied without, is installed simple and convenient.
(3) flexible operation mode multiplicity, that is, be manually operable, can also pass through remote control control.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the mounting structure schematic diagram of the utility model；
Fig. 2 is the circuit diagram of the utility model.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing and preferred embodiment.These attached drawings are letter
The schematic diagram of change, only illustrates the basic structure of the utility model in a schematic way, thus its only show it is related with the utility model
Composition.
As shown in Figs. 1-2, infrared emission sensor is installed on crack between a door and its frame side, when have object (finger) block sensor between
When infrared ray, sensor sends a signal to intelligent controller.Intelligent controller issues signal and starts electromagnetism after drive amplification
Clutch, electromagnetic clutch locking, door are not able to rotate.After receiving or pressing the Reset button, controller signals to electromagnetism
Clutch, clutch unclamp, and door can normal open and close.
It is AT89C52 single-chip microcontroller that controller core, which handles chip, and response is fast, and cost performance is high.Infrared emission sensor selection
Refined Zhuo science and technology GDK-5 model, high sensitivity, switching signal output.
3 keys of controller, function are as follows: P1.0 connects K1 key, starts by controller after lower button, P1.1 connect K2 by
Key presses the button rear controller and stops.P1.2 connects KS key, presses rear electromagnetic clutch and resets.P0.4 P0.5 connect two instructions
Lamp, green, which represents, to be operated normally, and red represents situation exception.Infrared emission sensor meets INTO pin (P3.1), and controller is adopted
The mode of " interruption " is taken to obtain infrared emission sensor signal.
Output signal prevents from interfering using photoelectric switch, with amplification drive module driving electromagnetic clutch movement.
Tetra- road wireless remote control module of RISYM-M4 is connect with P0.1-P0.3, receives remote keying signal, including starting, stopping, reset etc.
Signal.
The anti-interference of controller uses watchdog chip, and X25045 is connect with P2.1-P2.1, guarantees that system operates normally.
If there is failure, then system forced resetting.
It is specific embodiment of the present utility model described in above instructions, various illustrations are not practical to this
Novel substantive content is construed as limiting, and person of an ordinary skill in the technical field can be to former institute after having read specification
The specific embodiment stated is made an amendment or is deformed, without departing from the spirit and scope of utility model.
