Description
Technical field
The present invention relates to a kind of automatic monitoring device, particularly a kind of aid-to-navigation light operating state automatic monitoring device of realizing the transmitted in both directions of single lamp control and locating and displaying.
Background technology
Related standards according to International Civil Aviation Organization, aid-to-navigation light is the AC series supply power mode, promptly by dimmer power output constant current (the bright level of light divides Pyatyi to determine by electric current 2.8A～6.6A), be connected into high-tension circuit via the former limit of each isolating transformer, light for aid-to-navigation light by isolating transformer secondary output LOW voltage.This shows, it is safe that the aid-to-navigation light operating state detects and be controlled at the secondary low-pressure end automatically, but because the shielding buffer action of isolating transformer, particularly the temperature environment brought of sleety weather changes, and remote (more than several kilometers) of signal is transmitted bring bigger interference and distortion.The stable state amplitude-frequency characteristic of transmission network of actual measurement and transient state transient characteristic are random function when high pressure or low-pressure end insulation against ground resistance variations (particularly), therefore conventional modulation design is perfect in theory, but has bigger technical difficulty in practice.

(1) do not adopt servo-actuated peak value sampling circuit by what, the bright level of limitation light can accurately detect when being decided to be 3 grades, and (particularly 1 grade of light) causes the signal to noise ratio variation when the bright level of light changes, and it is relatively poor to expose the adaptability that the bright level of light is changed.
(2) intrinsic control circuit of chopping is paid attention to the intermediate frequency composition of copped wave and has been set up the two stage amplifer circuit.Simultaneously, the back-pressure and the frequency characteristic of copped wave pipe had higher requirement, the screening mortality is bigger, and still has potential faults.
(3) the synchronous carry circuit in the former design, the dimmer of having ignored employing controllable silicon lock stream mode is when low bright level is exported, and instrument transformer detects interference signal, may make the carry pulse counting error, thereby causes position error.
(4) do not possess real-time function in the former design,, confirm the location but must start shooting again if aid-to-navigation light in normal ignition, when damaging suddenly, can show trouble light.
(5) detection motherboard power supply switch and dimmer power switch are that parallel connection realizes synchronous start in the former design, and this has brought inconvenience for actual the use.
In view of this, in order to overcome above-mentioned shortcoming, further expand function, this creator is according to oneself practical experience and technical concept, after deliberation, exploitation, and has the present invention to produce eventually.
