Fig. 4 is the electrical schematic diagram of alarm;

Fig. 5 is the control circuit figure of junction box;

Fig. 5 is the observation circuit figure of junction box.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents total figure of the present utility model, and piece number 1 expression is installed in the aviation obstruction beacon on television tower shown in Figure 2 10, chimney 11, electric transmission pole tower 12 and the skyscraper 13.Every road aviation obstruction beacon is loaded on indoor junction box 2 by one and monitors, and all the monitoring of aviation obstruction beacon is undertaken by the watch-dog 3 that is loaded on central control room.Photosensitive probe 4 is loaded on outside the buildings, by reception environment brightness, is to close night daytime to open aviation obstruction beacon is carried out opening and closing.

Fig. 3 represents the electrical schematic diagram of watch-dog 3, and Fig. 3 top is control circuit, and the bottom is an observation circuit.Control circuit adopts dual time base circuit NE556, and previous time base circuit (the diagram left side) is connected into Schmidt trigger, and a back time base circuit is connected into multivibrator.When hand switch K closure (being the photoelectricity automatic control state), utilize the photosensitive probe 4 reception environment brightness that are connected to Schmidt trigger 2,4 pin, by regulating R ₁Resistance, make light-operated between the 5-250 Lux.Put one's cards on the table when environment and to be lower than light-operated point and promptly to need aviation obstruction beacon when flicker, it is big that photosensitive probe 4 resistance become, 2 pin of Schmidt trigger are low level, 5 pin are output as high level, 10 pin of the multivibrator of 5 foot control systems are high level, and the square wave that the output of 9 pin is certain drives each road junction box 2 work, shown in figure right-hand member arrow, glimmer to reach each road aviation obstruction beacon.When 9 pin output high level, triode 9013 conductings, LED and aviation obstruction beacon glimmer synchronously, to indicate.When ambient brightness greater than the return difference of light-operated point in limited time, photoresistance diminishes, 2 pin are high level, 5 pin are output as low level, 10 pin of 5 foot control systems are low level, 9 pin are output as 0, i.e. flicker free signal, aviation obstruction beacon stops flicker.Resistance R behind 9 pin ₂And capacitor C ₁For improving coupling effect and anti-interference the setting.Be connected to after 9 jiaos and be subjected to environmental interference setting for eliminating photosensitive probe with the preceding triode 9013 of Schmidt trigger 2 pin, when 9 jiaos of output high level, this triode conducting, 2 pin are low level, the circuit steady operation.

Observation circuit is seen the bottom of Fig. 3, by power supply, and 555, composition such as LED, relay.When the monitor signal (shown in the left end arrow of Fig. 3 bottom) from junction box 2 is a high level, represent promptly that this junction box monitors out that a certain small cup or many are broken down and when not glimmering, previous 555 2 pin are high level, and 3 pin are low level, and LED is bright to show that certain lamp breaks down.These 3 pin output levels of 555 through after one 555 reverse, make next 555 3 pin output high level, warning circuit 6 is connected in the relay J adhesive, sends sound and light alarm.

Warning circuit is seen Fig. 4, is made up of power supply, 555, controllable silicon 8, alarm lamp and loudspeaker etc.When relay adhesive shown in Figure 3, the power connection of warning circuit, 555 3 pin output positive pulse, controllable silicon 8 is opened, the alarm lamp flash of light, loudspeaker sends the pulse chimes of doom.

Warning circuit only just needs in running order when aviation obstruction beacon glimmers, and this is to realize afterwards by 5 pin that 555 4 pin in the observation circuit are connected in control circuit 556, referring to Fig. 3.When the aviation obstruction beacon flicker was 556 5 pin output high level, 555 4 pin were high level, 555 work, and observation circuit is in running order.

When the multichannel aviation obstruction beacon, every road junction box need establish 555 and LED, is parallel to the front portion of watch-dog observation circuit, and Fig. 3 only expresses the state of two road aviation obstruction beacons, when surpassing two the tunnel, adds 555 required and led circuit at dotted portion and gets final product.

The electric part of junction box comprises control circuit and observation circuit, and control circuit is that every lamp of this junction box of control glimmers, and observation circuit is that certain lamp of this junction box of monitoring is passed to watch-dog with fault-signal when breaking down and carried out sound and light alarm.

Fig. 5 represents the control circuit of junction box, is made up of two 555 impact dampers of forming 5, power supply, photoelectricity coupling 4N35 and power discharging transistors 9015 etc.2 pin that the start pulse signal that sends from watch-dog 3 enters impact damper 555 cushion amplification, through the 4N35 coupling, pass to each aviation obstruction beacon 1 trigger pip of this road through 9015 after amplifying again.

Fig. 6 represents the observation circuit of junction box, is made up of photosensitive device 7,556, integration timing circuit 9, LED, triode 9013 and 555, and photosensitive device places in every aviation obstruction beacon.When obstruction light 1 normal flash of light, the photosensitive device resistance reduces when flash of light, forms negative pulse, 6 pin of input 556, the capacitor C that 5 pin output positive pulse is given the integration timing circuit ₂Charging, 556 9 pin output low levels, LED does not work, and triode 9013 ends, 555 3 pin output low levels.When obstruction light 1 did not glimmer because of breaking down, the photosensitive device class value was constant, 556 5 pin no pulse output, and the integration timing circuit begins discharge, to capacitor C ₂When voltage is lower than 5V, 9 pin output high level, LED is bright, the triode conducting, 555 2 pin are low level, 3 pin output high level is same as shown in Figure 3, the relay adhesive, the warning circuit 6 of connection sends sound and light alarm.

Fig. 6 only expresses a junction box and monitors 1 the aviation obstruction beacon state in this road, during the monitoring multi-lamp, increases corresponding circuit at the diagram dotted portion and gets final product.

The utility model contrast prior art has following advantages: filled up monitoring device Blank; Connection dodges control ratio flexibly and is reliable; Every road control lamp number is more.
