Abstract
An adjustable program automatically controlled displayer comprises a programmable logic controller (PLC) and a signal collector. A support of the adjustable program automatically controlled displayer is composed of an upper support and a lower support, wherein the upper support and the lower support are connected through a rotating shaft, and an intelligent electric executing mechanism is installed on the lower support. The signal collector collects status signals of a human body and outputs a switch signal to the PLC, the PLC outputs a digital signal to the intelligent electric executing mechanism, the electric executing mechanism can rotate in positive and negative directions according to a control signal, and the intelligent electric executing mechanism drives the rotating shaft to rotate by a certain angle through a reducer. Due to the fact that a program control displayer rotates by a certain angle regularly, when people works, the head and the neck are 'forced' to change the position, and functions of rest, adjustment and relaxation can be achieved. The adjustable program automatically controlled displayer has the advantages of being simple in structure, full-automatic in control, convenient to use, and capable of playing a significant role in prevention of cervical disease and promotion of human health.
Description
Technical field
The present invention relates to appliance field, particularly relate to a kind of adjustable procedure auto-control display.
Background technology
Universal day by day along with office automation in recent years, cervical spondylopathy has occupied first of the orthopaedics incidence of disease, and more and more professional, become younger, the incidence of disease among the young crowd rises year by year.Because people use the computer office for a long time; online; forget oneself " rest " through regular meeting; make head for a long time; neck is in single postural position or a certain special body position; not only make the increased pressure in the cervical intervertebral disk; and make musculi colli be in non-coordination stress for a long time; nape muscle and ligament are tired easily; cause the cervical vertebra degenerationization gradually; cause the distortion of cervical spinal canal or intervertebral foramen; narrow and osteoproliferation; stimulate; the compressing cervical spinal cord; nerve root, and cause corresponding disease, as head; neck; shoulder; the back of the body; arm is ached; neck has a stiff neck, limitation of activity.Although some desktop computer display flips an angle before and after can be manually and regulates, do not have autoregulation, people are difficult to make neck to obtain having a rest and regulate when working before computer.People also can take certain methods to have a rest as promptings oneself such as alarm clock are set, but because many people have this spirit of working untiringly, also can often make head, neck be in single postural position or a certain special body position working time long, cause cervical vertebra fatigue, long-term accumulation forms cervical spondylopathy.Therefore, be necessary existing office tools is improved, make and before computer, work and the crowd who surfs the Net for a long time, can be changed head, neck location regularly, be in and regulate and the state that loosens, play the effect of pre-preventing cervical spondylosis.
Summary of the invention
Work untiringly when the objective of the invention is before computer, to work long hours or surf the Net at people, cause head, neck to be in single postural position for a long time and bring cervical vertebra strain problem, a kind of adjustable procedure auto-control display is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of adjustable procedure auto-control display, comprise display screen and bearing, also comprise Programmable Logic Controller (PLC) and signal picker, bearing is made up of upper bracket and undersetting, is connected by rotating shaft between upper bracket and the undersetting; Intelligent electric actuating mechanism and the speed reduction unit that is connected with electric operator are installed on the undersetting, carry out transmission by gear between speed reduction unit and the rotating shaft, display screen is connected with upper bracket;
Described signal picker is gathered the status signal of human body, output switching signal is to Programmable Logic Controller (PLC), by the PLC timing module, program by design is carried out sequential processing, according to the different sequential stage, send signal for the output module of PLC, make the output module output digital signal of PLC or (4-20MA.DC) give intelligent electric actuating mechanism (stepper motor), electric operator (stepper motor) can carry out the rotation of both forward and reverse directions according to control signal, and intelligent electric actuating mechanism drives rotating shaft by speed reduction unit and rotates to an angle.
As preferably, described electric operator is stepper motor, and motor has braking function.

Automatic control process is as follows:
(1) human body enters range of control, infrared inductor detects human body signal, sends a switching value signal to PLC, and the PLC timing module picks up counting, and does not reach t when human body hold-up time in sensing range
1The time, the PLC output signal does not change, and electric operator is motionless, and the hold-up time reaches t
1The time, the PLC output signal changes, and the electric operator action is rotated in the forward α.
(2) if t
1Back human body also is trapped in full t in the range of control
2, then PLC enters next step control, and output signal control electric operator action reversed is rotated 2 α, is no more than t if be detained
2, human body leaves range of control, and then PLC does not carry out next step control.
(3) at t
1+ t
2If human body is trapped in the range of control afterwards, then expire t
2After, the action of PLC output signal control electric operator is rotated in the forward α, discontented t
2, then the PLC output signal does not change, and electric operator is failure to actuate, and human body leaves the control area, and PLC does not enter next control program.
(4) if human body is trapped within the range of control always, PLC will repeat 1-2-3-1 ... step ordered pair electric operator is controlled.
Described t
1, t
2, the α value, the user selects according to individual human needs or arranges.
The present invention is by programmed control display rotating certain angle regularly, when people work, " force " human body head, neck to be shifted one's position, with the effect that reaches rest, regulates and loosen, it is simple in structure, and Automatic Control is easy to use, to pre-preventing cervical spondylosis, promote that people are healthy and have a vital role.
