Detailed Description

As shown in fig. 1, the emergency light remote monitoring device according to the embodiment of the present invention includes a processor, a wireless module, and a photosensitive sensor; the photosensitive sensor detects light signals of the externally mounted emergency lamp, the detection signals are transmitted to the AD sampling end of the processor and the wireless module, the processor and the wireless module further collect battery voltage signals of the emergency lamp and LED lamp strip voltage signals of the emergency lamp through the AD sampling end, and finally wireless communication is carried out with a remote control terminal through a wireless part. The device also comprises a relay for power distribution, wherein the input end of the relay is connected with an external AC power supply; the AC output end of the relay is connected with the emergency lamp to supply power and charge the emergency lamp; the DC output end of the relay is connected with the processor and the wireless module to provide a direct current power supply for the processor and the wireless module.

The present embodiment may work with the following process:

the relay converts AC220V AC to power the emergency light and converts DC to power the processor and wireless module.

The processor monitors the voltage of the battery (AD sampling) and the voltage of the lamp strip (AD sampling) in real time, and the abnormal condition is found and sent out through the wireless module.

3. The processor regularly controls the relay to be switched off, and the photosensitive sensor detects whether the emergency lamp can be automatically lightened. If not, the exception is sent out. (basic principle of judging whether emergency light works normally)

4. The wireless module may be a wireless transmission module of various frequencies.

As shown in fig. 2 and 3, in the relay DC output section, 12V is the converted DC voltage: u2 and U3 reduce the 12V that inserts twice to the 3.3V direct current that MCU processor required, supply the processor, wireless module and photosensitive sensor use.

As shown in fig. 4, the processor and the wireless transmission module are an MCU processor integrated with a wireless module, and can perform wireless data communication with other devices and servers. The circuit shown in fig. 5 and 6 collects the voltage of the battery and the lamp strip and accesses the voltage to the MCU through the sampling port for processing. The light sensitive sensor Q1 in fig. 7, passes the different light levels to the MCU (i.e., U1) for processing. The operation state of the entire system is indicated by the indicator lamp of fig. 8.
