Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent networking lighting, in particular to a high-voltage synchronous networking control power supply system. BACKGROUND

[0002] With the development of Internet of Things technology, the demand for environmental detection of intelligent lighting technology, especially for the detection of object activity in the corresponding environmental space, is becoming more and more extensive. Among them, the pyroelectric infrared sensor technology based on the partition of the corresponding detection area by the Fresnel lens to detect the cross-zone movement of the detection area and the microwave detection technology based on the Doppler effect principle are currently widely used activity detection technologies, which have wide application demand in the field of intelligent lighting. In traditional lighting equipment, based on the application demand of adding intelligent function, the object activity is detected based on the activity detection technology, and the working state of the lighting equipment is controlled according to the corresponding control logic based on the detection result, thereby realizing the intelligent control of the lighting equipment based on the object activity.

[0003] For parking lot lighting scene, highway lighting scene and staircase lighting scene, etc. cluster lighting scene, it is also necessary to control multiple lamps according to the detection results. The existing solution mainly uses wired networking to realize synchronous control networking. Specifically, the existing synchronous networking control system includes a host power supply and at least one slave power supply. The host power supply and the slave power supply respectively include a neutral input end N, a live input end L1 and a signal transmission end L'. The host power supply and the slave power supply are respectively connected to the lighting load. The neutral input end N and the live input end L1 of the host power supply and the slave power supply are respectively connected to the neutral line and the live line to adapt to the power supply of the lighting load. The signal transmission end L' of the host power supply is connected with the signal transmission end L' of the slave power supply. The host power supply is also connected with a sensor, and the power supply of the lighting load connected with the host power supply is controlled according to the detection result of the sensor. The signal transmission end L' of the slave power supply transmits signals to control the power supply of the lighting load connected with the slave power supply. Specifically, the existing synchronous networking control system outputs tri-state signals from the host power supply to the slave power supply to control the output of the slave power supply to realize the off, half-bright and full-bright states of the corresponding load. For example, the utility model patent with the patent number CN204906797U discloses a sensor and a power supply used in cooperation, which respectively output three states: 0V output, half-wave output and full-wave output to realize the full-on, half-on and off control of the load. For another example, the utility model patent with the patent number CN205546108U discloses a LED driver which can receive and convert tri-state signals to output corresponding high current, low current and no current to the LED load.

[0004] However, since the traditional power supply does not strictly distinguish the neutral input end N and the live input end L1 in the actual wiring process, it can work normally when the neutral input end N is connected to the live line and the live input end L1 is connected to the neutral line. Therefore, the operator is used to the wiring thinking of not distinguishing the neutral input end N and the live input end L1. When installing the host power supply and the slave power supply with synchronous networking function, the operator often misconnects the neutral input end N, the live input end L1 and the signal transmission end L', which often causes the burning of equipment components due to wiring errors, resulting in equipment failure accidents, commonly known as equipment explosion.

[0005] Specific reference FIG. 1A and FIG. 1BAs shown, the circuit structure of the existing host power supply is shown, the host power supply is set to turn on or off the optocoupler U7 or U8 according to the detection result of the sensor, when the live wire input end L1 and the signal transmission end L' are correctly connected, the optocoupler U7 or the optocoupler U8 is turned on, the host power supply will work normally and transmit signals to the slave power supply. When miswiring occurs, for example, the signal transmission end L' is mistakenly connected to the zero line, when the optocoupler U7 or the optocoupler U8 is turned on, the resistance R56 is electrically connected between the live wire and the zero line to form a high voltage, causing the resistance R56 to burn out, resulting in the host power supply blowing up.
