[0015] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. It is obvious that the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0016] Unless otherwise specified, the relative arrangement, numerical values ​​of the components set forth in these embodiments do not limit the scope of the present disclosure.

[0017] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0018] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0019] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0020] In order to solve the shortcomings of the traditional lighting system, the present disclosure proposes a venue lighting control system. Figure 1The present invention is a schematic diagram of an embodiment of a lighting control system for a venue disclosed herein, which specifically includes a first system for non-crowded areas of the venue and a second system for densely populated areas of the venue; wherein densely populated areas are areas with a large area and a large number of people gathered at the same time (see Article 73 (iv) of the Fire Protection Law of the People's Republic of China and Article 5.5.19 of the Code for Fire Protection Design of Buildings GB50016-2014), and vice versa, they are non-crowded areas.

[0021] Figure 1 In an embodiment of the present invention, the first system includes a tree network and a control platform, the control platform is connected to the root node of the tree network, some leaf nodes of the tree network are a first brightness sensing device, a human body sensing device, and a first actuator for controlling the turning on and off of a lamp, and the first brightness sensing device, the human body sensing device, and the first actuator for controlling the turning on and off of a lamp are arranged in a non-crowded area.

[0022] It should be noted that for areas with low pedestrian flow, lighting control needs to be considered from two aspects, namely, the lighting of the scene environment and whether there are people. In the first system, control can be performed based on these two factors. The control method is relatively conventional, that is, comparing the collected information with the threshold, and then performing corresponding control.

[0023] For example: when the light intensity is less than or equal to the first threshold (such as 20LX), turn on the lamp; when there is someone and the light intensity is less than or equal to the second threshold (such as 100 LX), turn on the lamp; when there is someone and the light intensity is greater than the second threshold (such as 100 LX), turn off the lamp; when there is no one and the light intensity is greater than the first threshold (such as 20LX), turn off the lamp.

[0024] That is, when no one is around, a smaller threshold is used to control the switch of the light fixture, and when someone is around, a larger threshold is used to control the switch of the light fixture. This control is a conventional existing control method, which can be implemented using a program and specifically loaded into the control platform. The first brightness sensing device and the human body sensing device will respectively sense the brightness (i.e., light) and whether there is someone around, and send these sensed data to the control platform through a tree network. The control platform sends corresponding instructions to the actuator according to the above control, thereby controlling the light to turn on and off.

[0025] It should be noted that the first brightness sensing device uses a light sensor, the manufacturer is ROHM, the model is BH1750FVI, which has the advantages of high sensitivity, wide range, low price, small size, etc., and is widely used in indoor and outdoor light detection scenes. The human body sensing device uses a human body infrared sensor, the manufacturer is Yatai Yingke, the model is HC-SR501, which has the advantages of high sensitivity, strong reliability, ultra-low voltage working mode, etc., and is widely used in various automatic sensing electrical equipment. The first actuator is a controllable switch, which can use a relay module, the manufacturer is Songle, the model is SRD series, which has the advantages of strong environmental adaptability, high stability, and long working life.

[0026] It should be noted that the control platform can be directly a server, which can be arranged in the computer room, or a computer. The data uploaded by the sensing device can be viewed in real time on the display screen, and the status of each component of the system can be viewed. The lighting equipment can be automatically (through program automatic control) or manually (such as by clicking the button on the display screen) controlled. Of course, the control platform can also use the existing network cloud platform. When the network cloud platform is used, the site manager can view the data and status at any time through computers, mobile phones, tablets and other terminal devices, and can also manually control the lighting equipment.

[0027] In some embodiments, when a server is used as a control platform, the server is connected to a router via Ethernet, the router is connected to an intelligent gateway via Ethernet, and the intelligent gateway is connected to the root node of the tree network via a USB data cable. This wired connection can ensure the stability of data transmission and improve data reliability. When a network cloud platform is used as a control platform, computers, mobile phones, tablets and other terminal devices are connected to the network cloud platform via the internet, the network cloud platform is connected to the intelligent gateway via the internet, and the intelligent gateway is connected to the root node of the tree network via a USB data cable.

[0028] ZigBee is a relatively mature wireless communication technology with eight major advantages: low power consumption, low rate, short delay, short distance, large capacity, low cost, high security, and license-free frequency band. In some embodiments, a tree network constructed using ZigBee wireless communication technology, that is, all nodes in the tree network are wirelessly connected through ZigBee modules, mainly including a coordinator, multiple routing nodes, and multiple terminal nodes. Figure 2 The coordinator is the root node of the tree network, the routing node is the child node and / or leaf node of the tree network, and the terminal node is the first brightness sensing device, the human body sensing device, and the first actuator, which are the leaf nodes of the tree network. Figure 2 Among them, 1 is the root node, 2 is the child node, and 3 is the leaf node.

[0029] It should be noted that the coordinator and routing node in the tree network can directly use ZigBee modules, and the leaf nodes are leaf nodes installed with ZigBee modules, that is, the first brightness sensing device, human body sensing device, and first actuator installed with ZigBee modules. This tree network can adapt to all current venues, and it is convenient for the system to expand or shrink according to changes in venue conditions, such as directly increasing or decreasing leaf nodes, or increasing or decreasing branches of the tree network.

[0030] It should be noted that the terminal node can be connected to the coordinator, or to the routing node as a child node, or to the routing node as a leaf node; the specific connection can adopt the principle of proximity, that is, the terminal directly connects to the nearest node. The tree network is used to facilitate system expansion.

[0031] Figure 1 In the embodiment, the second system is arranged in a crowded area, and includes a communication control module, a second brightness sensing device and a second actuator for controlling the lighting of the lamp, and the second actuator and the second brightness sensing device are both connected to the communication control module.

[0032] It should be noted that for crowded areas, it can be assumed that there are people in the area in real time, so when controlling, the second threshold can be directly used for control, that is, when the light is less than or equal to the second threshold, the lamp is turned on, and when it is greater than the second threshold (such as 100 LX), the lamp is turned off. This control is also a conventional existing control method.

[0033] The first system uses background control, that is, control platform control. This type of control will inevitably have a certain delay. Because of the control of lamps in crowded areas, in order to avoid equipment control delays and waste of network resources, the background can be directly separated. In other words, the above control method can be implemented directly in the communication control module. Such control has basically no delay, which means that the fastest lighting control is achieved.

[0034] It should be noted that the communication control module here can use a ZigBee module, the manufacturer is Newland, with a built-in CC2530 chip. In addition to wireless communication, it also supports embedded development to achieve point-to-point communication between modules.

[0035] The second brightness sensing device is consistent with the first brightness sensing device in terms of model and manufacturer, and the second actuator is consistent with the first actuator in terms of model and manufacturer, which are not fully described here.

[0036] The second brightness sensing device and the second actuator are both equipped with ZigBee modules, and the modules are wirelessly connected. The second brightness sensing device senses brightness (i.e., light) and sends the sensed data to the communication control module. The communication control module sends corresponding instructions to the second actuator according to the above control, thereby controlling the lighting of the lamp.

[0037] The first system of the utility model adopts a tree-like network structure, and the network root node is connected to the control platform. The platform uniformly performs intelligent lighting control on the lamps in the venue. Due to the tree-like network structure, when adding equipment, only a new device needs to be added as a leaf node, without changing the structure of the entire network. When reducing equipment, only the corresponding leaf nodes need to be removed. This system structure solves the problem that traditional lighting control systems are difficult to expand or reduce in the later stage. The second system realizes independent intelligent lighting control through the communication control module, and can be flexibly deployed according to specific areas in the venue (such as crowded areas), solving the problem of low lighting efficiency in traditional lighting control systems.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
