Formula, in the detection pattern, when the measured value of the first light intensity detector or the second light intensity detector not within the set threshold range
When, control unit, which sends alarm signal, to master control set and makes warning device alarm；First optical transmitting set and the second optical transmitting set
It is laser emitter.
The calculation method for specifically drafting duration is as follows: t=t1+t2；The t is to draft duration, and t1 is constant；T2 is equal to
The larger value among both t3 and t4；T3=T3 × (G/g), wherein T3 and g is constant, and G is the measured value of weighing device；t4=T4
× (1- (m/M)), wherein T4 is constant, and m is the quantity that can receive the optical receiver apparatus of optical signal of laser beam emitting device,

How much, duration maximum is drafted no more than some value.
As shown, the width of loading plate is substantially equal to the width of crossing, the people for needing to go across the road stands in loading plate
On, by the measured value of weighing device and the quantity of optical receiver, the number of number can be substantially judged, to adjust green light
Duration, number is more, and long green light time is longer.Weighing device is heavier, illustrates to need the people to go across the road more, can receive light letter
Number optical receiver apparatus it is fewer, illustrate to need the people that goes across the road how (more to blocking for optical path because people is more, and work as
People step on the first and second head when, optical path can also be blocked.In addition it is stepped on and is retracted in blind hole, can be protected to first and second
Cover plays a protective role).Traffic light systems are matched there are two signal lamp component, are located at the both ends of crossing, main
Control device can select the longer duration for drafting duration as following second time period in two signal lamp components.
Also, when periodic maintenance personnel safeguard signal lamp component, other than cleaning the first and second protective cover, also
Detection pattern can be executed, each protective cover of cleaning before detecting, and remove the foreign matter between each protective cover.Because for a long time
It uses, may result in spring fatigue, when the reasons such as movable block blocks lead to no external force, the first and second movable block is not capable of resetting.It is logical
The measurement for crossing the first and second light intensity detector can detecte out.Because under normal circumstances, the first optical transmitting set issue light according to
Secondary all starting staves and the second riser by the first protective cover, the light transmittance of the first and second riser be it is fixed, light
Decaying is fixed, therefore the measured value of the first light intensity detector should within the set threshold range, similarly, the inspection of the second light intensity
The measured value for surveying device also should be within the set threshold range.If within the set threshold range, not illustrating have protective cover not multiple
There is serious spot in position (where protective cover in blind hole, will lead to light can not be by the first and second riser) or protective cover
(optical path can be blocked), therefore alarm, remind maintenance.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
