Fig. 2 is a flowchart of an intelligent lighting control method according to a second embodiment of the present invention, and as shown in fig. 2, the intelligent lighting control method includes:
The characteristic information at least comprises a node type, a node ID and a current working state of the node.
Specifically, the intelligent lighting control system comprises a central control system, at least one area control system, at least one lighting control node corresponding to the area control system and a lighting system, wherein the lighting system comprises at least one lighting lamp, the central control system is connected with the area control system through a communication network, and the area control system is connected with the lighting control node through the communication network. After the intelligent lighting control system is powered on, the central control system performs initialization operation and self-check on the self state so as to perform fault detection; meanwhile, the regional control system performs initialization operation and self-checking on the self state so as to perform fault detection; meanwhile, the lighting control node performs initialization operation and self-checks the self state to perform fault detection. And then, constructing a communication network so that the central control system is connected with the regional control system through the communication network, and the regional control system is connected with the lighting control nodes through the communication network. The communication network CAN adopt a wired connection mode or a wireless connection mode, the wired connection mode includes but is not limited to a CAN bus and a 485 bus connection mode, and the wireless connection mode includes but is not limited to a ZigBee, wifi, Bluetooth (Bluetooth) and 2G \3G \4G connection mode. Preferably, in this embodiment, the communication network uses wifi or CAN bus as the communication link. Specifically, after each system and node perform initialization operation and construct a communication network, the lighting control node sends a registration packet to a corresponding regional control system through the communication network. Since practical problems such as link connection failure, frame loss, link congestion, etc. are likely to occur in the actual communication process, it is preferable that the lighting control node sends the registration data packet to the corresponding area control system through the communication network at regular intervals, for example, once every 1 second, to ensure that the lighting control node can successfully register.
Specifically, the area control system analyzes the registration data packet uploaded by the lighting control node, analyzes the node type, the node ID and the current working state of the node of the lighting control node, and determines the correctness of the registration data packet according to the node type, the node ID and the current working state of the node of the lighting control node, if the data packet uploaded by the lighting control node is determined to be a correct data packet without artificial tampering, the area control system performs secondary processing, such as cleaning, screening, filtering and the like, on the characteristic information of the lighting control node, and then packages the characteristic information of the lighting control node subjected to the secondary processing, and executes step 203.
Specifically, the regional control system transmits a registration packet to the central control system through the communication network, and at this time, the registration packet includes the characteristic information of the lighting control node subjected to the secondary processing.
And step 204, the central control system judges the correctness of the registration data packet according to the characteristic information of the lighting control node, if the registration data packet is judged to be the correct data packet, the step 205 is executed, and if not, registration failure information is returned to the lighting control node.
Specifically, the central control system analyzes the registration data packet uploaded by the regional control system, analyzes the node type, the node ID and the current working state of the node of the lighting control node, and judges the correctness of the registration data packet according to the node type, the node ID and the current working state of the node of the lighting control node, if the data packet uploaded by the lighting control node is judged to be a correct data packet which has not been artificially tampered, step 205 is executed, otherwise, registration failure information is returned to the lighting control node.
And step 205, the central control system returns registration success information to the lighting control nodes.
After the illumination control node receives the communication echo of the registration success information, the illumination control node is indicated to be successfully registered, in the subsequent process, the illumination control node does not send a registration data packet to the regional control system any more, but sends a heartbeat packet to the regional control system, and the regional control system uploads the heartbeat packet of the illumination control node to the central control system, wherein the heartbeat packet comprises the current working state of the illumination control node.
And step 206, the central control system sends a starting control instruction to the regional control system corresponding to at least one region according to a preset control strategy.
In this embodiment, each area corresponds to one area control system, the predetermined control policy includes a preset use state of each area in each set time period, and the use state includes a use state and an idle state. Specifically, if the use state of at least one area in a certain set time period is in the use state, the central control system sends a starting control instruction to the area control system corresponding to the at least one area when the set time period starts; and if the use state of at least one area in a certain set time period is in an idle state, the central control system sends a closing control instruction to the area control system corresponding to the at least one area when the set time period starts. For example, region a has a ratio of 07 on monday to friday: 00 to 22: the use state of the 00 time period is in the use state, and the ratio of area a to area b in the range of 00:00 to 07: time period 00, 22: 00 to 24: when the usage status of the time period 00 and the saturday is in the idle status, the usage status of the mobile terminal is 07: 00 to 22: when the time period 00 begins, the central control system sends a starting control instruction to the area control system corresponding to the area A, and the starting control instruction is set in the range from 00:00 to 07: time period 00, 22: 00 to 24: at the beginning of the 00 time period and the saturday, a shutdown control command is sent to the zone control system corresponding to the zone a.
In this embodiment, the predetermined control policy may be set by a manager with authority, and when the intelligent lighting control system of this embodiment is applied to a school lighting control system, the predetermined control policy may be set according to a teaching curriculum schedule of a school, and this embodiment does not limit the predetermined control policy at all. In this embodiment, a manager with authority records a predetermined control policy into the central control system in advance.
And step 207, the area control system sends a starting control instruction to at least one lighting control node corresponding to the area control system, wherein the at least one lighting control node comprises a light control node, a curtain control node, a people number detector and a light detection node.
Specifically, if the central control system issues a start control instruction, the regional control system sends the start control instruction to at least one lighting control node corresponding to the regional control system; and if the central control system issues a closing control instruction, the regional control system sends the closing control instruction to at least one lighting control node corresponding to the regional control system. Preferably, the at least one lighting control node includes, but is not limited to, a light control node, a shade control node, a people detector, and a light detection node.
And step 208, the curtain control node opens all the curtains in the area according to the starting control instruction.
Specifically, the shade control node opens all shades in the area according to the start control instruction, or the shade control node closes all shades in the area according to the close control instruction. The curtain control node comprises a curtain control circuit, specifically, the curtain control circuit opens all curtains in the area according to the starting control instruction, or the curtain control circuit opens all curtains in the area according to the closing control instruction. In this step, whether the window covering in the area needs to be opened or not may be determined according to the actual situation, and is not limited herein.
And step 209, the light control node starts the corresponding light illumination system according to the starting control instruction.
Specifically, the light control node turns on the corresponding light illumination system according to the start control instruction, or the light control node turns off the corresponding light illumination system according to the turn-off control instruction. The time length of turning on the lighting system may be from a time period before the start of the set time period to a time period after the end of the set time period, for example, the set time period is 7:00 to 22:00, and the time period is 30 minutes, then the time length of turning on the lighting system is 6:30 to 22: 30. That is, when the use state of the area in the set time period 7:00 to 22:00 is the use state, the central control system may also send a start control instruction to the area control system at 6:30, so that the area control system controls the corresponding lighting system to be turned on through the lighting control node according to the start control instruction, and send a turn-off control instruction to the area control system at 22:30, so that the area control system controls the corresponding lighting system to be turned off through the lighting control node according to the turn-off control instruction.
And step 210, detecting the number of the personnel in the area and the position area of the personnel by the number of people detector according to the starting control instruction, and uploading the number of the personnel in the area and the position area of the personnel to an area control system.
And when the closing control instruction is received, the people number detector does not work according to the closing control instruction.
And step 211, if the area control system judges that the number of the personnel in the area is greater than the set value, acquiring the current illumination value of the area where the personnel are located through the light detection node.
Specifically, if the area control system determines that the number of people existing in the area is greater than a set value, the current illumination value of the area where the people are located is obtained through the light detection node. Wherein the set value may be 0. Specifically, if the area control system determines that the number of people existing in the area is greater than 0, the light detection node is started, and the brightness of the light of the environment in the area where the people are located is detected through the light detection node, so that the current illuminance value of the area where the people are located is obtained.
And when the closing control instruction is received, the light detection node does not work according to the closing control instruction.
In step 212, the area control system determines whether the absolute value of the difference between the current illuminance value and the preset standard illuminance value is greater than a preset threshold, if so, step 213 is executed, and if not, no brightness adjustment is performed on the current lighting system.
Specifically, if the area control system determines that the absolute value of the difference between the current illuminance value and the preset standard illuminance value is greater than or equal to the preset threshold, it indicates that the difference between the current illuminance value and the standard illuminance value is large, and therefore, the brightness of the current lighting system needs to be adjusted, and therefore, step 213 is executed. If the area control system judges that the absolute value of the difference value between the current illumination value and the preset standard illumination value is smaller than the preset threshold value, the difference value between the current illumination value and the standard illumination value is smaller, and therefore the brightness of the current lighting system does not need to be adjusted.
And step 214, the area control system adjusts the brightness of the lighting system in the area where the person is located through the lighting control node until the current illumination value of the area where the person is located is equal to the standard illumination value.
In this embodiment, in the operation process of the lighting system, some functions of personalized control may not be implemented in the predetermined control strategy, and therefore, some areas with personalized control requirements need to be temporarily adjusted in a personalized manner. For example, in some areas, there may be a special area where a projector is used, and at this time, the area may not need to turn on the lighting system when the projector is used, and at this time, the manager with authority may manually control the lighting control node to turn off the corresponding lighting system. When the working state of the lighting control node is manually controlled, for example, a lighting control node is manually controlled to turn off a corresponding lighting system, the lighting control node uploads manually-operated control information to the central control system through the regional control system, and the central control system records the control information and optimizes the control means of the central control system according to the control information to obtain a personalized control means. In the subsequent control process, a prompt is given on a human-computer interface terminal connected with the central control system so that a manager with authority can control the illumination of the area corresponding to the illumination control node. It is understood that the intelligent lighting control of the embodiment can be realized by an automatic control mode of the central control system and a manual control mode of the lighting control nodes, the two control modes are compatible, the central control system can control the working state of the lighting control nodes through a control strategy to realize the intelligent lighting control, and the lighting control nodes can also upload the characteristic information such as the working state of the lighting control nodes to the central control system in real time for managers with authority to make lighting decisions, so that the real-time and personalized lighting requirements are met. In this embodiment, the human-machine interface terminal may be configured to display information such as a use state of each area at each set time and an illumination condition of the lighting system in each area.
In this embodiment, the intelligent lighting control method may be applied to a lighting control system of a school, and in this case, each area may include, but is not limited to, a teacher area, a corridor area, a conference room area, an office area, a laboratory area, and a fire passage area. The at least one zone control system may include, without limitation, a teacher zone control system, a hallway zone control system, a conference room zone control system, an office zone control system, a laboratory zone control system, a fire passage zone control system.

On the other hand, adopt central control system, regional control system and lighting control node three layer construction, control whole lighting system, not only can control opening and closing of light lighting system, can also adjust the luminance of light, through adopting the mode of closed-loop control illumination intensity, can carry out accurate control to the illuminance of ambient light. Meanwhile, the system is compatible with an automatic control mode of a central control system and a mode of manually controlling the lighting control nodes, and meets the requirements of real-time and individualized lighting.
