Description

Laser navigation trackless extensible door system

Technical field

The utility model relates to a kind of trackless extensible door system, particularly relates to a kind of laser navigation trackless extensible door system.

Background technology

Electric extendable door is a kind of novel gate that opens and closes with stretch mode, and it is handsome in appearance with it, can electronicly control, and is applicable to advantage such as random length and extensively adopts.At present, existing magnetic navigation trackless extensible door needs boring on the ground.Bury guiding magnet underground, and the permanent back magnet magnetic of using weakens problems such as easy generation derailing.Patent 2004200965660 discloses a kind of light controlled linear running gear of railless electric retractable door, it places the outside, retractable door two ends respectively with infrared transmitting device, infrared receiver, shadow shield is arranged at and drives on the head, launch, receive the operation of control gate by infrared rays, in this technical scheme, because it is infrared rays is subject to the interference of ambient light (as sunlight), high to precision, the working environment requirement of infrared receiver; And because the correction receiving system is positioned at the both sides of shade, thereby can't when operation, whether derail by the decision gate body, cause difficult enforcement.In addition, also can't realize the function that relative straight line is split.

Summary of the invention

In view of above problem, the purpose of this utility model is: provide a kind of trackless extensible door system, particularly a kind of laser navigation trackless extensible door system.

In order to reach above purpose, the utility model has adopted following technical scheme: at first adopted general purpose control circuit, correction circuit and warning circuit, emitter is arranged at the retractable door fixed end, receiving screen is arranged at retractable door and drives on the head, one or one group of grating model are arranged before the light-sensitive element on the receiving screen, filter stray light, by utilizing the photoelectric effect of receiving screen light-sensitive element, corresponding generation navigation, deviation correcting signal are come in position according to laser pick-off on the receiving screen, and play the purpose of anti-creep when retractable door is closed.

The utility model has the advantages that by above technical scheme installation is simple, convenient, equipment working stability, safety, energy conservation, environmental protection.

Description of drawings

As shown in Figure 1, be structured flowchart of the present utility model;

As shown in Figure 2, be structural representation of the present utility model;

Fig. 3 is the vertical view of Fig. 2.

The specific embodiment

As shown in Figure 2, the utility model mainly comprises: emitter (1), control circuit, warning circuit, correction circuit, receiving screen (2).Wherein before the light-sensitive element circuit board on the receiving screen (2) one or one group of grating breast board are arranged, hole on the grating breast board or groove can guarantee that the light vertical with receiving screen shines on the receiving screen, filter and disturb light.

Because emitter (1) and receiving screen (2) lay respectively on the fixed gate body (3) and driving head (4) of retractable door, thereby can realize that the relative straight line of retractable door splits.As shown in Figure 2.

When retractable door will be moved, laser head emission laser (shown in the dotted line among Fig. 1, Fig. 2) on the emitter (1) on the retractable door fixed gate body, can receive laser in the middle of being installed in the receiving screen (2) on the retractable door driving head, because the photoelectric effect of light-sensitive element on the receiving screen, produce corresponding current/voltage and change, and then check generation Navigation Control signal by control circuit.Depart from when the retractable door body moves, at this moment correct position generated deviation correcting signal by corresponding control circuit in the middle of the laser that receiving screen (2) receives can depart from, and corrected the direction of motion of a body.

In addition, when the retractable door complete shut-down, the laser head on the emitter (1) also can continue emission, if there is the people to ascend from door body top, can hinder the reception of receiving screen (2) to laser, sends alarm signal by related circuit, thereby plays the effect that anti-creep is reported to the police.

Claims (2)

1. laser navigation trackless extensible door system, it comprises: control circuit, correction circuit, warning circuit is characterized in that: go up at retractable door fixed gate body (3) laser beam emitting device (1) is installed, drive head (4) in retractable door and go up receiving screen (2) is installed.

2. laser navigation trackless extensible door system according to claim 1 is characterized in that: one or one group of grating breast board are arranged before the light-sensitive element circuit board on the receiving screen (2).
