Abstract
The utility model discloses a material level detecting device of a material storing warehouse. The material level detecting device of the material storing warehouse comprises a laser generation circuit, a light signal receiving circuit, a control circuit and a power circuit, wherein the light signal receiving circuit corresponds to the laser generation circuit in position, the control circuit is respectively connected with the laser generation circuit and the light signal receiving circuit, and the power circuit is connected with the control circuit. The material level detecting device of the material storing warehouse detects materials in the warehouse through the photoelectricity induction principle, original parts forming the material level detecting device are mature in technology in the present market, a single part is low in cost, and the material level detecting device of the material storing warehouse can be conveniently, extensively and widely used.
Description
Technical field
The utility model belongs to warehouse material detection range, especially relates to a kind of storage warehouse material-level detecting device.
Background technology
Materials such as picture cereal, silo, cement, colliery again can not be open-air, again can not be moist.So various enclosed storage warehouses are invented, since but be the enclosed material level of not seeing the inside again, so various level-sensing device is also fallen over each other radar level gauge, ultrasonic material level detection unit, blocking rotary type level-sensing device, capacitance level meter etc.But these level-sensing device costs are all very high, and the developing low-cost level-sensing device helps to reduce the production cost of entire product.
Summary of the invention
The defective too high in order to remedy above-mentioned material detecting instrument cost, that single product can't widespread use the utility model proposes a kind of storage warehouse material-level detecting device, adopts the mode of photoelectricity combination to detect height of materials, saves the cost of manufacture of instrument.
The technical scheme that realizes above-mentioned beneficial effect is, a kind of storage warehouse material-level detecting device, comprise laser beam generating circuit, the optical signal receiving circuit corresponding with the laser beam generating circuit position is respectively with the laser beam generating circuit control circuit that is connected with optical signal receiving circuit and the power circuit that is connected with control circuit.
Described control circuit also is connected with display circuit and reset circuit.
The utility model comes material in the warehouse is detected by the optoelectronic induction principle, and the original paper of forming this device is in technology maturation in the market, and cost per unit is low, is convenient to extensive extensively practical.
