Description
Technical field
The present invention relates to the fine setting of optical fiber video camera, control photography automatically.Specifically, relate to based on current-controlled optical fiber camera motion micromatic setting.
Background technology
World today's optical fiber technology develops rapidly, and, advantages such as starting material wide, little loss low with its cost are widely used in every field.Wherein the optical fiber video camera is the model that camera technique combines with optical fiber transmission technique, the high a plurality of fields such as military affairs, earthquake search that are applied to of, flexibility ratio little owing to optical fiber video camera volume, therefore fine setting is very necessary for the optical fiber video camera under specific environment, but the control of its movement velocity and direction becomes the main bottleneck of restriction, and rely on of moving of elder generation's stage optical fiber video camera handed the action and the working direction of stretching out optical fiber and can not control camera part more.Ripe optical fiber camera motion micro-tensioning system does not appear at present as yet through investigating.
Summary of the invention
For overcoming the deficiencies in the prior art, move the problem that is difficult to control moving direction and speed at the optical fiber video camera, provide a kind of based on current-controlled optical fiber camera motion micromatic setting, to realize control near the air-flow environment optical fiber, and then the shooting direction of change optical fiber video camera, reach the accurately control effect of fine setting, for achieving the above object, the technical solution used in the present invention is, based on current-controlled optical fiber camera motion micromatic setting, utilization electromagnetic relay principle, utilize the closure of the switch control that is provided with on the different circuit and the corresponding electromagnetic relay of circuit, open, the closure of electromagnetic relay, open opening and closure of control air vent switch, thus the size of air-flow in the control air-flow transport pipeline, and the control air-flow blows the optical fiber video camera and realizes camera position is finely tuned.
The pressure size that provides according to required air pump in air-flow velocity, the system's cavity is selected the spring that suitable elasticity coefficient is arranged in the electromagnetic relay and the number of turns of electromagnet, thereby the effect that reaches accurate control air-flow orientation realizes fine setting optical fiber video camera.
The present invention has following technique effect:
1, adopt by peripheral by rule arrangement guide pipeline at optical fiber camera fiber section, and special processing pore position of living in
Put, open in order again and closed pore combination of holding allocation, thereby the present invention can realize the optical fiber video camera is finely tuned;
2, utilization electromagnetic relay principle is controlled, thereby the effect that reaches accurate control air-flow orientation realizes fine setting optical fiber video camera.

Embodiment
Ultimate principle is introduced:
According to the principle of acting force and reacting force, pore sprays the gas stream of specific flow velocity to certain direction, can produce expulsive force in the other direction to pore and carrier.Measure camera and fiber section weight, calculate required drive and default gas flow rate, optical fiber camera quality is low weight, power is provided for the motion of optical fiber camera to reciprocal acting force in the time of can making the gas ejection in order to specific speed.
Utilization electromagnetic relay principle is set up circuit, controls the connection that different switches are realized different circuit, control the opening of switch of pore with closed with electromagnetic relay, the "on" position lower electromagnet is magnetic, and attracts armature to open air-flow delivery tube road junction, opens wireway; The off-position lower electromagnet is invalid, and armature is owing to spring tension covers the guide pipeline opening, closed wireway.By calculating the air-flow velocity of gained, the pressure size that required air pump provides in the computing system cavity, as according to selecting the spring that suitable elasticity coefficient is arranged in the electromagnetic relay and the number of turns of electromagnet, thereby the effect that reaches accurate control air-flow orientation realizes fine setting optical fiber video camera.
Basic layout according to the warning device of new principle design:
Go out the prototype of system according to principle design, be divided into three parts.
First is an air-stream generating device, can provide pressure in the specific cavity by the certain power air pump, realizes the air-flow of output required flow rate, and air pump can place single unit system inside, also can be external, provide air flow source by closed conduit for system.
Second portion is the pore control section, has overlapped circuit, and the correct electromagnetic relay of the utilization number of turn produces the attractive force of suitable size, is that armature overcomes pressure unlatching in the pump.The corresponding air vent switch of contactor is mapping relations, and different contactors are opened the different air vent switch combination of combination mapping.Electromagnetic relay provides need be to the realization of physical action from the user, thereby can realize that the advance and retreat of camera and direction change (circuit diagram is seen accompanying drawing).
Third part is for carrying conduction gas part and motion control part, 12 minimum air guide tubules of quality prolong the inside and outside two-layer arrangement of the regular branch of optical fiber outer wall, optical fiber is by two groups of air guide tubule group clampings, inside and outside two-layer airflow direction is fixed, gas flow rate is fixed, wireway road junction opening direction is fixed, rationally controlled air flow switch and opened closed combination, be i.e. control advance and retreat and break-in campaign (accompanying drawing is seen in conduit arrangements and the explanation of air vent openings direction).
Can more accurately control optical fiber camera small movements, avoid operating blindly and cause camera bad, touch some article and cause damaging and causing danger.
In the process of military or alert usefulness, can slightly control the activity of optical fiber camera lentamente, carry out hidden and careful detecting, good reliability is disguised strong, and precognition is dangerous, ensures one's own side personnel's safety; In explosive process or dangerous material detection process, both can reach the effect of observation, can carefully avoid touching again and cause danger.
In the disaster relief process, accurately change the activity of optical fiber camera, can overcome optical fiber camera light weight and be difficult to difficulty in the small space activity, more easily kept away obstacle, realize that the rescue in down-hole or the ruins is surveyed.
