Background technology
Voyage aid of the airport lamp system be ensure aircraft normally take off under night, low visibility and other complicated weather condition,
The necessary visual navigational aids land, slided.The most conventional voyage aid of the airport lamp system is typically all and uses series circuit to helping
Boat lamp provides power supply, and in airfield aid loop, aid-to-navigation light isolating transformer is powered light adjusting system for aid-to-navigation light
One of important composition equipment, its winding is in series connection constant current major loop, each according to voyage aid of the airport lamp system by dimmer
Lighting level sets, Secondary Winding power to aid-to-navigation light；Each isolating transformer is all connected to each other by plug and socket, thus forms
Aid-to-navigation light supply network.The functional reliability of voyage aid of the airport lamp system is closely related with aircraft safety, but the performance meeting of aid-to-navigation light
Because the factor such as surrounding and its shelf-life goes wrong, thus affect the properly functioning of airport, therefore to aid-to-navigation light working condition
It is monitored particularly significant.Present domestic a lot of airports all use aid-to-navigation light cruising inspection system to examine aid-to-navigation light working condition
Survey, but current this aid-to-navigation light cruising inspection system is general and aid-to-navigation light shares Secondary Winding, the most once aid-to-navigation light cruising inspection system
Breaking down and will directly affect the normal work of aid-to-navigation light, if it addition, isolating transformer secondary side open circuit, aid-to-navigation light is patrolled and examined and is
System is impossible to be monitored aid-to-navigation light state, and therefore in aid-to-navigation light is monitored, isolating transformer fault detect is a difficult point.
Current this aid-to-navigation light cruising inspection system is not easy to judge the open-circuit condition of isolating transformer, and aid-to-navigation light is once opened a way, to confession
Electricity major loop can have a great impact.
Summary of the invention
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of aid-to-navigation light isolating transformer open-circuit condition
Monitoring device.
In order to achieve the above object, in the aid-to-navigation light isolating transformer open-circuit condition monitoring device that this utility model provides
The vice-side winding of isolating transformer is constituted double winding output, isolating transformer former by mutually isolated main winding and auxiliary winding
Two ends, limit are connected with two terminals of main circuit power supply respectively；Described aid-to-navigation light isolating transformer open-circuit condition monitoring device
Including detection sensor, power switch, supply module and single-chip microcomputer monitoring means；Wherein, main winding and current sensor, power
Switch and aid-to-navigation light form aid-to-navigation light loop, and power switch is in parallel with aid-to-navigation light, and current sensor is serially connected in main winding and merit
Between the parallel branch of rate switch and aid-to-navigation light composition；Auxiliary winding is connected with single-chip microcomputer monitoring means by supply module, uses
In providing power supply for single-chip microcomputer monitoring means, single-chip microcomputer monitoring means is connected with detection sensor and power switch respectively.
Aid-to-navigation light loop and detection in the aid-to-navigation light isolating transformer open-circuit condition monitoring device that this utility model provides
Unit current supply circuit is individually power supply, and the two is independent of each other；And can interpolate that out that aid-to-navigation light isolating transformer is opened a way；When
Detecting when aid-to-navigation light is opened a way, single-chip microcomputer monitoring means controls power switch Guan Bi, thus avoids aid-to-navigation light open circuit main to power supply
Loop impacts；When aid-to-navigation light or detector unit break down, main circuit power supply still can normally work.
Accompanying drawing explanation
The structural representation of the aid-to-navigation light isolating transformer open-circuit condition monitoring device that Fig. 1 provides for this utility model.
Detailed description of the invention
The aid-to-navigation light isolating transformer open-circuit condition prison with specific embodiment, this utility model provided below in conjunction with the accompanying drawings
Survey device is described in detail.
As it is shown in figure 1, the isolation in the aid-to-navigation light isolating transformer open-circuit condition monitoring device of this utility model offer becomes
The vice-side winding of depressor 2 is constituted double winding output, the former limit of isolating transformer 2 by mutually isolated main winding 4 and auxiliary winding 3
Two ends are connected with two terminals of main circuit power supply 1 respectively；Described aid-to-navigation light isolating transformer open-circuit condition monitoring device
Including detection sensor 5, power switch 6, supply module 7 and single-chip microcomputer monitoring means 8；Wherein, main winding 4 and current sensor
5, power switch 6 and aid-to-navigation light 9 form aid-to-navigation light loop, and power switch 6 is in parallel with aid-to-navigation light 9, and current sensor 5 is serially connected in
Between the parallel branch of main winding 4 and power switch 6 and aid-to-navigation light 9 composition；Auxiliary winding 3 is by supply module 7 and single-chip microcomputer
Monitoring means 8 connects, for providing power supply for single-chip microcomputer monitoring means 8, single-chip microcomputer monitoring means 8 respectively with detection sensor 5
