To ensure that the lighthouse operates reliably, lighthouses of the present disclosure may include multiple light bulbs, which may also be controlled by the lighthouse monitoring system.
When the lighthouse comprises a plurality of bulbs, the bulbs are connected in parallel and then connected in series with the normally closed contact and the coil of the second relay 31.
Referring to fig. 3, the lighthouse monitoring system further includes a control sub-circuit 40, wherein the control sub-circuit 40 is connected to each of the light bulbs, and controls light bulbs in each of the light bulbs to be powered on after the th normally closed contact is closed.

The prompter 32 may include a warning light, among other things. The alarm 32 may also include an audible and visual alarm or the like.
In order to further clarify the implementation principle of the present disclosure at , the present disclosure uses the circuit block diagram shown in fig. 2 as an example to illustrate the working flow of the present disclosure.
In the present disclosure, the light detector 10 may be a photoreceptor, for convenience of description, the th relay is referred to as relay M1, the second relay 31 is referred to as relay M4, the third relay is referred to as relay M2, the fourth relay is referred to as relay M3, and the prompter 32 may be an alarm lamp.
Based on the above structure, under the condition that the sunlight is normal (the brightness of the external light reaches the threshold value), the photoreceptor senses that the coil (namely, the coil M1 in FIG. 2) of the light relay M1 is electrified, the normally closed contacts M11 and M12 are disconnected, the lighthouse is not electrified, and the alarm lamp does not work. When the light is too dark (the brightness of the external light does not reach the threshold value), the photoreceptor disconnects the connecting circuit, the coil of the relay M1 is powered off, the normally closed contacts M11 and M12 are switched on, the lighthouse is powered on, and the alarm lamp loop starts to work.
lamp towers can be installed with a plurality of bulbs at the same time, bulbs are broken, the circuit can be automatically switched to other bulb circuits, taking three bulbs installed in the lamp towers as an example, after a normally closed contact M11 is closed, the lamp towers start to work, a 1# bulb circuit is electrified to work, because a coil (namely a coil M2 in figure 2) of a relay M2 is electrified, normally closed contacts M21 and M22 are disconnected, a 2# bulb circuit and a 3# bulb circuit are disconnected, only the 1# bulb is on at the moment, because of the problems of service life and the like, if the 1# bulb fails, the 1# bulb circuit is powered off, a coil of a relay M2 is powered off, a normally closed contact M21 is closed, the 2# bulb circuit is connected, the 2# bulb is on, a coil (namely a coil M3 in figure 2) of the relay M3 is electrified, a normally closed contact M3 is disconnected, the 3# bulb circuit is still in a power-off state, only the 2# bulb is powered on at the moment, and if the subsequent 2# bulb fails, the normally closed contact M3 is powered off, the relay M3 is powered on, the bulb circuit.
When the lighthouse works, the fault alarm loop starts to work. I.e. after the normally closed contact M11 is closed, the lighthouse starts to work, while the normally closed contact M12 in the malfunction alerting circuit is also closed. If the lighthouse works normally, namely a bulb loop is electrified, so that a coil (namely a coil M4 in figure 2) of the relay M4 is electrified, a normally closed contact M4 in the fault alarm loop is disconnected, and an alarm lamp is not lighted. If all bulb return circuits of the lighthouse are not electrified, the coil of the relay M4 is electrified, the normally closed contact M4 in the fault alarm return circuit is closed, and the alarm lamp is on to inform operation and maintenance personnel to overhaul.
In order to conveniently show the time length of the fault of the lighthouse, when the prompter 32 comprises an alarm lamp, the alarm lamp can comprise a timer and a plurality of indicator lamps, and the indicator lamps respectively display light with different colors after being turned on, correspondingly, the second normally closed contact is closed, and when the lighthouse is not electrified, indicator lamps in the indicator lamps are turned on, the timer is used for timing, and after the timing is different in time length, whether the lighthouse is still not electrified is judged, if the lighthouse is still not electrified, the indicator lamps corresponding to the time length are controlled to be turned on, so that the fault time length of the lighthouse is marked according to the light with different colors.
For example, when the beacon is detected to be abnormally working initially, a green indicator lamp is correspondingly turned on, when the beacon is obtained to be abnormally working in th time period, a yellow indicator lamp is correspondingly turned on, when the beacon is obtained to be abnormally working in the second time period, a red indicator lamp is correspondingly turned on, and the like.
It should be understood that the indication of the abnormal duration of the lighthouse may also be accomplished in other ways. For example, the prompter 32 may include a timer that counts the length of the lighthouse anomaly and a display through which it is displayed. The display is selected for display, abnormal duration of the lighthouse can be visually displayed, and therefore user experience is improved.
Referring to fig. 4, the lighthouse monitoring system may further include a solar power generation assembly, the solar power generation assembly is mounted outside the lighthouse, and the solar power generation assembly is connected to the rechargeable battery 53 and charges the rechargeable battery 53.
The rechargeable battery 53 may be used as a backup power source for the lighthouse monitoring system to supply power to the lighthouse monitoring system. Thereby ensuring reliable operation of the lighthouse monitoring system.
The solar power generation assembly comprises a solar panel 51 and a rectifying circuit 52, the solar panel 51 is installed outside the lighthouse, the rectifying circuit 52 is electrically connected between the solar panel 51 and the rechargeable battery 53, and the electric energy generated by the solar panel 51 is processed by the rectifying circuit 52 and then transmitted to the rechargeable battery 53, so that the rechargeable battery 53 is charged.
On the basis, the disclosure also provides lighthouse monitoring methods, which are applied to the lighthouse monitoring system, the method comprises the steps that a light detector 10 detects external light in the environment where a lighthouse is located, when the brightness of the external light reaches a threshold value, a master control loop 20 is triggered to disconnect the power supply from the lighthouse, so that the power supply stops supplying power to the lighthouse, and when the brightness of the external light does not reach the threshold value, the light detector 10 triggers the master control loop 20 to connect the power supply with the lighthouse, so that the power supply supplies power to the lighthouse and triggers the fault detection circuit 30 to work.
The fault detection circuit 30 monitors whether or not the lighthouse is lit, and prompts when the lighthouse is not lit
The lighthouse monitoring system and the lighthouse monitoring method have the advantages that by the arrangement of the light detector 10, the master control loop 20 and the fault detection circuit 30, light in the environment where the lighthouse is located can be detected by the light detection equipment, when the external light brightness does not reach the threshold value, the power is connected with the lighthouse through the master control loop 20, the power is supplied to the lighthouse, and therefore the lighthouse is lightened when the external light brightness does not reach the threshold value. And when the external light brightness reaches the threshold value, the power supply for the lighthouse is stopped, and the lighthouse is closed, so that unnecessary energy consumption is avoided. After supplying power to the lighthouse, the fault detection circuit 30 is triggered to work, whether the lighthouse is lightened or not is monitored through the fault detection circuit 30, and prompt is given when the lighthouse is not lightened, so that related personnel can maintain the lighthouse in time, and reliable work of the lighthouse is ensured.
