Fifth embodiment, as shown in fig. 5, which is a first embodiment of the present invention, is a top view of a general household, and a main control unit is used in the system, and is composed of a single chip microcomputer stm32f4504, a WiFi module 505, and an external memory 506; the system comprises three

slave control units

501, 502 and 503, namely slave control units 1, 2 and 3, wherein the slave control unit 1(501) comprises a singlechip stm32f1507, a WiFi module 508, an infrared module 509, an ultrasonic module 1510 (position 524 is marked in the schematic diagram due to special position, the same below), an ultrasonic module 2511 (position 525 in the schematic diagram) and an illumination module 512; the slave control unit 2(502) is composed of a singlechip stm32f1513, an infrared module 515, a sound module 516 and a lighting module 517; the slave control unit 3(503) is composed of a single chip microcomputer stm32f1519, an infrared module 520, a photosensitive module 521, a sound module 522 and an illumination module 523.

Since the main control unit 504 can be placed at any position, a specific position is not shown in the drawing. The following scenario description is made:

firstly, the master control unit 504 performs networking, and accesses all the

slave control units

501, 502 and 503 to the network to perform initialization preparation; after initialization is finished, first communication between the master control unit and the slave control unit is carried out, and information such as whether a manual mode is set, whether a current sensor of each slave control unit works normally, whether a lighting module works normally and the like is counted; and entering a standby mode after all the sensors are ready, and waiting for the sensor group of the slave control unit to be triggered.

At this point, no people are in the entire room, so all room lighting fixtures are off.

When a person enters or exits from the gate 526, the ultrasonic module 1524 is triggered first, meanwhile, the infrared module 509 of the slave control unit 501 detects that the person enters or exits, the two sensors simultaneously sense that the slave control unit 501 controls the lighting module 512 to be turned on according to the current time (supposing that the night) and the environment after the person enters or exits, and simultaneously sends the information to the master control unit 504, and the master control unit sends early warning information to the

slave control units

502 and 503 through analysis and prediction, so that the

lighting modules

517 and 523 are turned on slightly and record the information in a user database, and the information is used for making a user habit table.

If no next action of the user is detected, the

slave control units

502 and 503 will extinguish the slightly lit lighting modules after a period of time; if the user enters the door 529, the ultrasonic sensor 1524 detects the distance change and the infrared module 509 of the slave control unit 1 loses the sensing, and at this time, the message is sent to the master control unit 504; the master control unit 504 warns the slave control unit 3503 again, and when the infrared module 520 and the sound module 522 of the slave control unit 503 simultaneously detect that an object enters, the lighting module 523 is turned from slight lighting to full lighting, and meanwhile, the lighting module 512 of the slave control unit 1501 enters into a turn-off countdown. The user enters 528 the same thing and returns to the vicinity of the slave unit 501.

If the current day is the daytime, the data collected by the photosensitive module 521 is used to determine whether the day is cloudy, and the data is uploaded to the main control unit 504 to determine whether the lamp needs to be turned on.

The master control unit can predict the user movement according to the recorded user data, for example, when a user arrives at home between 9 o 'clock and 9 o' clock in the evening, the master control unit controls the lighting unit of the slave control unit 501 to be slightly bright during the period from 9 o 'clock to 9 o' clock, and detects that someone enters the slave control unit to be fully bright; for example, since a user normally enters only room 529 when he or she is at home, only the light of room 527 and the room where slave control unit 501 is located are notified of the slight lighting without slightly lighting the light of room 528 when it is detected that the user leaves room 529.

Sixth embodiment a second embodiment of the invention is shown in fig. 6, which illustrates an example of a warehouse application. The basic architecture of the master and slave units in this example is the same as that in example five except that the sensors used are slightly different and will not be described herein. In FIG. 6, 601 and 602 are two gates entering a warehouse, and 603-610 are all slave control units.

When no one is left in the warehouse, the lighting modules of all the slave control units are in a closed state, when someone opens the

gate

601 or 602, the lighting modules of 603, 605 and 606 are lighted, and the master control unit is informed, and in the case of no day or night, the lighting problem does not exist for the closed warehouse, so that the lighting is convenient when someone enters the warehouse. When the

slave control unit

603 or 606 detects that a person or a vehicle enters, the lighting module of the slave control unit to which the predicted path belongs is turned on.

In the scene, the system can be supplemented with a warehouse query system, namely when the goods to be searched are queried, a navigation road is formed by using light, the light belonging to the path from the personnel position to the front of the goods shelf is turned on, and the light at other places is turned off.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
