There is pulse counter；The pulse counter by electrical control pulse to being punched on counter wheel；The utility model is by counter wheel
On axle loaded on rotation, coordinate pulse counting equipment to carry out positive reverse count, reach the purpose accurately controlled；Pass through electrical control
Counting mode, simple in construction, cost is low, easy care, and more simple, more reliable than using rotary encoder, service life is permanent.
A kind of rotation counting device of described flexible scraper-trough conveyer can carry out step-by-step counting, but accurately can not sentence automatically
Disconnected forward backward counter, the precision that the precision of used electrically step-by-step counting does not have photoimpact to count are high.The present invention uses light
Electric pulse, which counts, can fast and accurately judge forward backward counter, and the precision counted is also very high.
The content of the invention
It is an object of the invention to provide a kind of pulse counting equipment with forward backward counter function, to solve the above-mentioned back of the body
The traditional counting equipment processed complex proposed in scape technology is difficult in maintenance and the problem of can only unidirectionally counting.
To achieve the above object, the present invention provides following technical scheme：
A kind of pulse counting equipment with forward backward counter function, including：

Baffle plate is arranged on photoelectric code disk side；
Light emitters, it is arranged on the opposite side of photoelectric code disk and sends the first light and the second light, photoelectric code disk
Condenser is installed between light emitters；
Signal receiving circuit, it is located at the side that photoelectric code disk is equipped with baffle plate, and the signal receiving circuit is electrically connected with
Oscillograph.
Preferably, it is described by the first light of grating and the width for being smaller than baffle plate of the second light.
Preferably, the quantity of described grating is N number of, N >=1.
Preferably, the light intensity for the first light that described light emitters are launched is strong more than the light of the second light
Degree.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is calculated by the number to these photoimpacts and caused speed can extrapolate sender set
Turnning circle and velocity of rotation, and the device may determine that the rotation direction of photoelectric code disk, and difference is turned so achieving that
Pulse caused by dynamic direction rotation is counted respectively, and so as to realize forward backward counter function, mechanism is simple and can be accurate
True counting, later maintenance are simple.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Embodiment：
Fig. 1 to Fig. 3 is referred to, when device is counted, launches the first light a and second by light emitters 4
Light intensity of the light intensity for the first light a that light b, wherein light emitters 4 launch more than the second light b, first
Light a and the second light b directives condenser 5, collimated light beam, described light are gathered into by condenser 5 by the light beam of diverging
Transmitter 4 is arranged on the opposite side of photoelectric code disk 2, and condenser 5 is provided between photoelectric code disk 2 and light emitters 4.Carry out
Rotating shaft 1 followed by external drive device and rotate during counting, and then the photoelectric code disk 2 being fixed in rotating shaft 1 turns with rotating shaft 1
Move and rotate, when such as Fig. 3 is rotated clockwise for rotating shaft 1, the first light a and the second light b and directive that are assembled by condenser 5
Equal angular one week grating 3 installed in photoelectric code disk 2, the baffle plate 6 of the side of photoelectric code disk 2 is arranged on by the directive of grating 3
On, wherein the width for being smaller than baffle plate 6 for the first light a and the second light b for passing through grating 3, now the first light a leads to
The gap crossed among baffle plate 6, and the second light b is then sheltered from by baffle plate 6, and then the first light a directives signal receives electricity
On circuit element D in road 7, wherein circuit element D is photodiode, is converted optical signals into receiving the first light a
Electric signal, electric signal is amplified by the amplifying circuit in signal receiving circuit 7, it is amplified after electric signal pass to company
It is connected in the oscillograph 8 of pin Vout in signal receiving circuit 7, records the oscillogram of electric signal in oscillograph 8, and then
Counted.
When rotating shaft 1 rotates counterclockwise, now the second light b is by the gap among baffle plate 6, and the first light a is then
Sheltered from by baffle plate 6, finally also record the oscillogram of electric signal in oscillograph 8, because light emitters 4 are launched
The first light a light intensity be more than the second light b light intensity, so the oscillogram when rotating clockwise of rotating shaft 1
Highly it is more than the height of the oscillogram when rotating counterclockwise of rotating shaft 1, and then forward backward counter can be carried out.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
