Description

A kind of stopping means of electric extendable door control system

Technical field

The utility model relates to a kind of stopping means of electric extendable door control system.

Background technology

(or claim: stopping means) roughly be divided into two classes: a class is the limit switch of contact to the limit switch of electric extendable door control system, electric extendable door touches mechanical switch when switch puts in place, make switch closure and make retractable door do the action that stops, another kind of is contactless limit switch, during use, generally adopt spacing underground digging and bury magnet, the induction of making reed pipe dry up comes identification switch spacing.The limit switch of contact is because switch loose contact easy to wear, easy, and need install and fix frame for movement, bother, now replaced by contactless limit switch basically, but adopt and bury magnet spacing underground digging, the construction working amount is big, cause ground destroyed, and tongue tube is overhead too closely fragile, in rainy day moisture-sensitive and cause signal to misread again.

For this reason, Chinese patent application numbers 200610033562.1, the solution that name is called the patent application proposition of " electric telescopic door ultrasound wave spacing and anti climbing detector " is: utilizing hyperacoustic range measurement principle is the length of opening the door and closing the door that automatic retractable door is measured automatic retractable door, and the length of removing the spacing position of infrared rays, and the output control signal sends to main control MCU, conduct is opened the door and the signal of door-closing in-place when main control MCU detects, the motor of controlling automatic retractable door is out of service, remove infrared limit signal when detecting, thereby make the disabler of infrared anti-collision, make electric extendable door can be in the scope of setting switch, close the door spacing after, utilize clocklike transmitting of its transmission course as the correlation source, carry out the anti-creep induction, when detecting signal when being hindered by obstruction, thinking has people or obstruction to climb retractable door and send the warning sound, thereby realizes the anti-creep warning.The device of this patent application comprises some rows of head and connection thereof, it is characterized in that, this head is provided with ultrasonic emitting probe and ultrasonic wave receiving transducer, and tail end door row is provided with and described ultrasonic emitting probe and the corresponding ultrasound reflector of ultrasonic wave receiving transducer, described head is built-in with EEPROM, counter, indicator lamp and the drive motors of main control MCU and connection thereof, and is provided with the anti-creep alarm and is connected with described main control MCU.But its weak point is: because ultrasonic emitting probe and ultrasonic wave receiving transducer are installed on the automatic retractable door, automatically the door row on the retractable door understands the ultrasonic wave that the reflection supersonic wave transmitting probe sends sometimes automatically, makes the misconnection of ultrasonic wave receiving transducer receive reflected signal and causes the misoperation of electric extendable door control system.

Summary of the invention

The purpose of this utility model is exactly to receive reflected signal and to cause the shortcoming of the misoperation of electric extendable door control system to be improved above-mentioned receiving transducer misconnection, and a kind of novel stopping means of electric extendable door control system is provided.The technical scheme that realizes the purpose of this utility model is as follows: the novel stopping means of electric extendable door control system described in the utility model is divided into two parts, wherein, first is provided with first single-chip microcomputer, first transmitter, and first receiver, second portion is provided with second singlechip, second transmitter, and second receiver, the output of described first receiver is electrically connected with the input of first single-chip microcomputer, the output of first single-chip microcomputer is electrically connected with the input of first transmitter, the output of described second receiver is electrically connected with the input of second singlechip, and the output of second singlechip is electrically connected with the input of second transmitter.

Of the present utility model have a following advantage: during use, can be because of the electric extendable door ultrasonic wave that sends of reflection supersonic wave transmitting probe automatically sometimes, and make the misconnection of ultrasonic wave receiving transducer receive reflected signal and cause the misoperation of electric extendable door control system.The utility model is a very commercioganic new product.

Description of drawings

Fig. 1 a kind of circuit block diagram of the present utility model.

The specific embodiment

Specific embodiment below in conjunction with accompanying drawing further specifies the utility model.(but not being) to restriction of the present utility model.

As shown in Figure 1, be the circuit block diagram of a kind of specific embodiment of the present utility model.As seen from the figure, the stopping means of electric extendable door control system described in the utility model is divided into two parts, wherein first is provided with first single-chip microcomputer 1, first transmitter 2, and first receiver 3, second portion is provided with second singlechip 4, second transmitter 6, and second receiver 5, the output of described first receiver 3 is electrically connected with the input of first single-chip microcomputer 1, the output of first single-chip microcomputer 1 is electrically connected with the input of first transmitter 2, the output of described second receiver 5 is electrically connected with the input of second singlechip 4, and the output of second singlechip 4 is electrically connected with the input of second transmitter 6.

The first above-mentioned transmitter 2 is provided with first transmitting probe, and the first transmitting probe input and the first radiating circuit output are electrically connected, and first transmitter 2 can be ultrasonic transmitter, and then second receiver 5 correspondingly is a ultrasonic receiver; Described second transmitter 6 is provided with second transmitting probe, the second transmitting probe input and the second radiating circuit output are electrically connected, second transmitter 6 is ultrasonic transmitter or RF transmitter or generating laser, and then first receiver 3 is ultrasonic receiver or infrared receiver or laser pickoff accordingly; First receiver 3 is provided with first receiving transducer, and the first receiving transducer output and the first receiving circuit input are electrically connected; Second receiver 5 is provided with second receiving transducer, and the second receiving transducer output and the second receiving circuit input are electrically connected.

If first transmitter 2 is a ultrasonic transmitter, second receiver 5 correspondingly is a ultrasonic receiver, send signal A by first transmitter 2, import second singlechip 4 into behind second receiver, the 5 received signal A, signal A transfers signal B to through second singlechip 4, send signal B by second transmitter 6, this second transmitter 6 also is a ultrasonic transmitter, and first receiver 3 also is a ultrasonic receiver, import first single-chip microcomputer 1 into behind first receiver, the 3 received signal B, calculate the distance between first single-chip microcomputer and the second singlechip behind first single-chip microcomputer, the 1 received signal B, compare the switch work of sending operation signal control electric extendable door control system limit switch according to data in the memory in the distance that calculates and the single-chip microcomputer.To send signal B different because above-mentioned first transmitter 2 sends signal A and second transmitter 6, like this, just can be because of not understanding the ultrasonic wave that the reflection supersonic wave transmitting probe sends sometimes automatically on the retractable door automatically, make the misconnection of ultrasonic wave receiving transducer receive reflected signal and cause the misoperation of electric extendable door control system.Second transmitter 6 also can be RF transmitter or generating laser, and then first receiver 3 is infrared receiver or laser pickoff accordingly.

More than be a kind of embodiment of the present utility model, all similar changes of doing according to above-mentioned design ought to belong to scope of the present utility model.
