As shown in fig. 6, the working flow of the intelligent energy-saving system for tunnel lighting of the present invention includes the following steps:
step S10, detecting whether there is vehicle entering the tunnel, if so, executing step S20;
in step S10, detecting and judging whether the vehicle is about to enter the tunnel is realized through the ground induction coil detecting component;
step S20, starting a vehicle speed detector to measure the speed of the vehicle and acquiring the average speed of the vehicle;
step S30, obtaining the illumination intensity outside the tunnel; in step S30, illumination intensity acquisition is achieved by the illumination detector.
Step S40, the ZigBee controller receives the illumination intensity and the average speed through the 4G communication module;
step S50, the ZigBee controller confirms the corresponding first power supply signal according to the illumination intensity; the first power supply signal comprises a first power supply voltage, and the corresponding relation between the illumination intensity and the first power supply signal is stored in the storage module; for example, the intensity of light includes low light and high light; the first power supply signal includes a high voltage corresponding to low illumination and a low voltage corresponding to high illumination. For example, the high voltage is 220V, the low voltage is 110V, and high illumination indicates that the external brightness is high, such as in a daytime state; low illumination means that the external brightness is low and the lamp is in a night state; the ZigBee controller sends high voltage to the power supply module, the power supply module outputs the high voltage to the LED lamp to shine with high brightness, and if the ZigBee controller sends low voltage to the power supply module, the power supply module outputs the low voltage to the LED lamp to shine with low brightness.
In step S50, preferably, the ZigBee controller confirms the corresponding first power supply signal according to the illumination intensity, and the ZigBee controller calculates the power supply duration according to the detected vehicle speed. The power supply duration represents the duration of time that the power supply module provides the output voltage to the LED lamp; the main functions are as follows: after the vehicle enters the tunnel, the LED lamps in the tunnel area are gradually turned off, and energy-saving control is achieved. For example, the detection speed is 40 km/h, and the corresponding power supply duration is 10 seconds; detecting the vehicle speed to be 80 km/h, and correspondingly, the power supply duration time to be 5 seconds; the luminous duration of the LED lamps in the tunnel is controlled, and the intelligent power-saving technical effect is achieved.

where v is the detected average vehicle speed, vmAt a preset maximum vehicle speed, T1For a preset power supply duration; l isoIndicating the length of the LED lamp from the tunnel entrance. Based on the formula utilized above, the duration of the corresponding power supply to the respective power supply module connected to each LED lamp in the tunnel can be accurately calculated. Is favorable for intelligently saving electricity.
Step S60, the ZigBee controller sends a first power supply signal to each power supply module connected with the LED lamp through the lora communication module;
for step S60, more preferably, the ZigBee controller transmits the first power supply signal to each power supply module connected to the LED lamp according to the distance of the LED lamp from the tunnel entrance through the lora communication module; it can be understood here that the closer the power supply module is to the tunnel entrance, the earlier the first power supply signal is received; more specifically, the ZigBee controller sends the first power supply signal to each power supply module connected to the LED lamp according to the distance from the LED lamp to the tunnel entrance through the lora communication module specifically includes:
step S61, the ZigBee controller calculates the sending time according to the distance between the LED lamp and the tunnel entrance; the sending time represents the time when the ZigBee controller sends the first power supply signal to the power supply module connected with the LED lamp;
wherein the second formula utilized in step S61 is:
specifically, v is the detected vehicle average speed, vmAt a preset maximum vehicle speed, ToThe method comprises the steps that preset time for sending a first power supply signal is adopted, t is sending time, the sending time represents the time for actually sending the first power supply signal, the sending time is increased according to a set time interval, t is more than or equal to 0 and less than or equal to L/v, and L is the length of a tunnel.

The principle is that the power supply module corresponding to the LED lamp closer to the tunnel entrance receives the power supply signal earlier, so that the LED lamps in the tunnel are sequentially lightened according to the distance from the tunnel entrance. The one-by-one illumination takes the condition of each LED lamp into consideration, and has an intelligent power-saving effect.
And step S62, the ZigBee controller sends the first power supply signal to each power supply module connected with the LED lamp according to the sending time. And the power supply module triggers the duration countdown of each power supply module after receiving the first power supply signal, and resets the duration countdown if the corresponding LED lamp is in the lighting state.
The preferred embodiment can precisely control the time when each first power supply signal reaches the corresponding power supply module through the settings of the steps S61 and S62; namely, the starting time of each LED lamp in the tunnel can be different according to the position of the vehicle in the tunnel; the power-saving effect can be effectively improved.
Step S70, judging whether the LED lamp is on; if not, step S80 is performed; if yes, resetting a light-out countdown;
step S80, the ZigBee controller sends the power supply duration time to each power supply module connected with the LED lamp through the lora communication module;
for step S80, it is more preferable that: the ZigBee controller sends power supply duration time to each power supply module connected with the LED lamp according to the distance between the LED lamp and the tunnel entrance through the lora communication module;
in step S80, the power supply duration time has been calculated in advance in step S50; the power supply duration is the same for each LED lamp; only the sending time is different; step S80 has the effect that the ZigBee controller sends the power supply duration time to each power supply module connected with the LED lamps in sequence according to the arrangement sequence of the LED lamps in the tunnel through the lora communication module; the specific sending time may refer to the second formula adopted in step S61; and will not be described in detail herein.
Step S90, the power supply module outputs corresponding voltage to the LED lamp according to the first power supply signal, and triggers lamp-out countdown; the display brightness of the corresponding LED lamp is controlled according to the illumination intensity outside the tunnel.
And step S100, the power supply module stops outputting the corresponding voltage according to the power supply duration time, namely, the light-off countdown is finished, and the corresponding voltage is stopped outputting.
In step S100, after each power supply module supplies power to the LED lamp connected thereto according to the power supply duration; and stopping outputting the corresponding voltage so that each LED lamp is orderly turned off. The LED lamp in the intelligent control tunnel is turned off, and a better power saving technical effect is achieved.
