Abstract
The utility model discloses a novel optical module is turn -offed to intelligence, including transmit section branch, delay circuit and receiving part, transmit section divides including light emitting devices, interconnected circuit A and laser -driven ware, receiving part includes light receiving element, interconnected circuit B and limiting amplifier, and receiving part connects delay circuit and exports control signal through its inside limiting amplifier, and transmit section divides the other end and the light receiving element 1 who connects delay circuit through its inside laser -driven ware. This practical novel optical module is turn -offed to intelligence can realize optical module receiving terminal intelligent control transmitting terminal, when down video line goes wrong, can let go upward the control scheme shutoff, also turn -offs another circuit when it not only can let a certain circuit go wrong and reduces the consumption to can pass through the real -time suggestion line fault problem of this kind of function.
Description
Technical field
The utility model relates to a kind of shutoff optical module, and specifically a kind of novel intelligent turns off optical module.
Background technology
Prior art be about under optical module image information that camera photographed real-time pass control and monitor console back, and control and monitor console also can be sent to camera by optical module and allows the instruction of cloud platform rotation, realizes 360 degree of overall view monitorings.The internal receipt of optical module and radiating portion are completely independently, they are transmission video signal and control signal two circuits respectively, if and in actual applications wherein a road go wrong, what so another road became does not have purposes, such as when the circuit of transmission of video goes wrong, image can not pass control and monitor console back, at this moment cradle head control circuit necessity not with regard to becoming, only remaining power consumption.
Utility model content
The purpose of this utility model is to provide a kind of novel intelligent to turn off optical module, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of novel intelligent turns off optical module, comprise radiating portion, delay circuit and receiving unit, described radiating portion comprises light emitting devices, coupling circuit A and laser driver, described receiving unit comprises light receiving element, coupling circuit B and limiting amplifier, receiving unit is connected delay circuit by the limiting amplifier of its inside and is exported control signal, and radiating portion connects the other end and the vision signal of delay circuit by the laser driver of its inside.
As preferred version of the present utility model: the output butt coupling circuit B of described light receiving element, the other end of coupling circuit connects limiting amplifier.
As preferred version of the present utility model: the other end of the output butt coupling circuit A of described laser driver, coupling circuit A connects light emitting devices.
Compared with prior art, the beneficial effects of the utility model are: the utility model intelligence turns off optical module can realize optical module receiving terminal intelligence shutoff transmitting terminal, when video line goes wrong, control circuit can be allowed also to turn off, it not only can reduce power consumption when circuit goes wrong, and cue circuit that can be real-time is abnormal.
Accompanying drawing explanation
Fig. 1 is the structured flowchart that novel intelligent turns off optical module.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of novel intelligent turns off optical module, comprise radiating portion, delay circuit and receiving unit, described radiating portion comprises light emitting devices, coupling circuit A and laser driver, described receiving unit comprises light receiving element, coupling circuit B and limiting amplifier, receiving unit is connected delay circuit by the limiting amplifier of its inside and is exported control signal, and radiating portion connects the other end and the vision signal of delay circuit by the laser driver of its inside.
The output butt coupling circuit B of light receiving element, the other end of coupling circuit connects limiting amplifier.
The other end of the output butt coupling circuit A of laser driver, coupling circuit A connects light emitting devices.
Operation principle of the present utility model is: laser driving chip all at present has a TX-DISABLE function, and it can input a level by outside and whether provide electric current normally work to control driving chip to allow laser.This programme mainly adopts lossing signal prompting (LOS) function of optical module receiving terminal limiting amplifier inside, when optical module does not receive light signal, this function will start, export a level prompting and confiscate light, we can input to this LOS level the TX-DISABLE launching driving chip, are used for controlling driving chip and whether provide current drives laser works.Thus reach the function utilizing receiving terminal to automatically shut down transmitting terminal.Output to the accuracy of TX-DISABLE level in order to ensure LOS, export add a delay circuit at LOS, when LOS level changes, TX-DISABLE can change after time delay a period of time again.
