Description

Technical Field

[0001] The utility model relates to a DALI intelligent system, belonging to the technical field of DALI lighting systems. Background Art

[0002] LED (Lighting Emitting Diode) lighting is light emitting diode lighting. A light emitting diode is a semiconductor solid-state light-emitting device that uses a solid semiconductor chip as a light-emitting material. The excess energy released by carrier recombination in the semiconductor causes photon emission, directly emitting red, yellow, blue, green, cyan, orange, purple, and white light.

[0003] LED lighting products are lighting devices that use LED as a light source. Using LED as a light source, different lamp types are combined to form a lighting system. Existing building exteriors and outdoor landscapes, as well as office interior lighting, home interior and garden lighting, hotel and shopping mall lighting, etc. mostly use area division to control lighting, while the lighting of building exteriors and outdoor landscapes is simply turned on or off, using simple lighting effects to present the shape and color of buildings and outdoor landscapes.

[0004] However, the existing systems for controlling LEDs are relatively cumbersome, difficult to connect, and unable to achieve large-scale centralized control of DALI devices. The number of devices controlled by a single DALI bus is limited, the number of devices controlled by a single system is small, and the response efficiency is low. Utility Model Content

[0005] The purpose of the utility model is to provide a DALI intelligent system, which can realize large-scale DALI equipment centralized control, break through the number of single DALI bus control equipment limit, increase the number of single system control exponentially, effectively reduce the centralized control delay and improve the response efficiency. At the same time, it combines the advantages of DALI control reliability and RS485 communication mode (Modbus communication) high compatibility, and has significant advantages in large-scale integrated control scenarios.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A DALI intelligent system comprises a main controller, a host computer, a switch panel, at least one DALI host, multiple DALI drivers and multiple load LEDs, wherein the host computer, the switch panel, each DALI host and the main controller communicate in an RS485 communication mode; each DALI host communicates with multiple DALI drivers in a DALI protocol; multiple DALI drivers are respectively connected to multiple load LEDs in a one-to-one correspondence; wherein the host computer is used to remotely or locally control the load LEDs through the DALI host and the DALI driver; and the switch panel is used to control the load LEDs in real time through the DALI host and the DALI driver.

[0008] Preferably, the RS485 communication method adopts Modbus protocol.

[0009] The beneficial effects of the utility model are:

[0010] 1. The system is simple, easy to connect, and saves installation costs; it can realize large-scale DALI device centralized control, breaking the limit on the number of devices controlled by a single DALI bus, and the number of single-system controls has doubled, effectively reducing centralized control delay and improving response efficiency. At the same time, it combines the advantages of DALI control reliability and RS485 communication mode (Modbus communication) high compatibility, and has significant advantages in large-scale integrated control scenarios.

[0011] 2. The host computer and switch panel can be controlled separately, accurately positioned, and save labor costs;

[0012] 3. DALI protocol has the characteristics of high reliability and strong control specificity as the terminal control device communication, but it is not conducive to the integration of general function control, and requires a dedicated controller to realize the centralized control function. Therefore, modbus protocol is used as the main communication method; modbus protocol is mature, reliable, widely used, and widely used in the field of industrial control equipment. This controller system adopts modbus RTU communication protocol, which has good compatibility as the master and slave ends. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is specifically introduced below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown: This embodiment is a DALI intelligent system, including a main controller, a host computer, a switch panel, at least one DALI host, multiple DALI drivers and multiple load LEDs. Among them, the host computer, the switch panel, and each DALI host are connected to the main controller; each DALI host is respectively connected to multiple DALI drivers, and multiple DALI drivers are respectively connected to multiple load LEDs in a one-to-one correspondence.

[0018] The DALI host and DALI driver use the standard DALI communication protocol, and each DALI host can connect to up to 64 DALI drivers; the main controller and DALI host use RS485 communication and standard Modbus protocol (modbusRTU communication protocol), and each main controller can connect to up to 128 DALI hosts; the switch panel is an optional accessory, and it uses RS485 communication with the main controller, which can adjust the load LED in real time; the host computer is an optional accessory, and it uses RS485 communication with the main controller, which can remotely or locally adjust the load LED in real time, and also has functions such as time calibration and fault recording.

[0019] The DALI host is connected to the bus centralized control through Modbus. The main controller implements the main business logic, divides the data point table of the control device (DALI host) into three memory units: "real-time data", "control data" and "configuration data", and performs data mapping in the main controller to achieve the purpose of standardized and unified control. The mapping of data is protected by a specific private internal protocol. The control data is secondary protected on the basis of the general modbus communication to ensure the reliability and anti-intrusion of the data. The control strategy and core algorithm are integrated in the main controller, which uses the performance of the high-performance processor and the precise processing of memory data to generate control recipes in a shorter time. Combined with the advantages of multiple RS485 buses, the control strategy is issued to the DALI device synchronously.

[0020] This system can realize large-scale DALI device centralized control, breaking through the limitation of the number of devices controlled by a single DALI bus, and doubling the number of single system control, effectively reducing the centralized control delay and improving the response efficiency. At the same time, it combines the advantages of DALI control reliability and high compatibility of conventional Modbus communication, and has significant advantages in large-scale integrated control scenarios.

[0021] In this embodiment, the main controller, the host computer, the switch panel, the DALI host, the DALI driver and the load LED are all existing devices, and those skilled in the art can purchase them according to their needs.

[0022] The above is only a preferred implementation of the utility model patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model patent. These improvements and modifications should also be regarded as the protection scope of the utility model patent.
