Description
A kind of specification elevator optoelectronic switch technical field
The utility model is related to a kind of optoelectronic switch, more particularly to a kind of elevator optoelectronic switch.
Background technology
With the continuous social and economic development, oneself application through increasingly being popularized of elevator.Current elevator generally uses frequency conversion control technique; and the traction motor power of elevator would generally be in more than 15KW; powerful converter technique will necessarily produce larger interference to power network; interference signal can directly affect the optoelectronic switch as flat bed inductor; load abnormal or remarkable action can be caused; serious meeting, which causes photoelectricity Jian to close, can not correctly reflect the level position of elevator, even result in elevator and close people or the security incident such as rush to summit.Therefore, just seem as the reliability of the optoelectronic switch of Elevator landing inductor and be even more important.
Technical problem to be solved in the utility model is to provide a kind of elevator optoelectronic switch, with the function such as excessively stream short-circuit protection and elimination external interference signals.
The utility model solves the technical scheme that its technical problem used：A kind of elevator optoelectronic switch is provided; infrared emission including being sequentially connected receives integrated circuit; the output end that the infrared emission receives integrated circuit is connected by triode with light emitting diode, and the base stage of the triode is also connected with excessively stream short-circuit protection integrated circuit.
The excessively stream short-circuit protection integrated circuit is realized by BTS4140 chips.
The infrared emission receives integrated circuit and realized by IS471F chips.
The power end that the infrared emission receives integrated circuit is connected with mu balanced circuit.
The mu balanced circuit is thtee-stage shiplock voltage stabilizing circuit.
The circuit output end of pressure-stabilizing is parallel with output filter capacitor.
The mu balanced circuit input is parallel with input filter capacitor.
The mu balanced circuit input is also parallel with transient voltage suppressor.
The mu balanced circuit input is in series with current-limiting resistance and the diode for preventing electric voltage reverse-connection.
Beneficial effect
As a result of above-mentioned technical scheme, the utility model compared with prior art, has the following advantages that and good effect：The utility model adds excessively stream and short-circuit protection integrated circuit, output interface caused by making load abnormal due to load excessive or external interference signals can be avoided to damage completely, and from causing whole circuit to be in voltage stabilizing shape all the time by mu balanced circuit
State.
