Technical Field

The invention relates to a sensing control system, in particular to a DALI addressable intelligent sensing control system.

Background

Light and illumination control technology is continuously developed along with the development of electronic technology and computer technology. In the 60's of the 20 th century, direct digital control technology (DDC), which emerged to improve control accuracy and flexibility, was then applied to automatic lighting control; in the late 80 s and 90 s of the 20 th century, Distributed Control (DCS) rapidly dominates the field of industrial control as computer network technology is developed and applied in control systems. Then, in order to realize the communication between the distributed control system and the controllers and sensors, the industrial control technology of the field bus is rapidly developed into the mainstream technology. The intelligent light and illumination control system based on the field bus technology is characterized in that a field bus is used as a link to connect single scattered lamps or sensing measuring devices, so that the lamps or the sensing measuring devices communicate information with each other, the intelligent control tasks of local light and illumination are jointly completed, and the intelligent light and illumination control in a remote or larger range can be realized by further combining the internet technology. The intelligent light and illumination control adapts to the direction of the development of the light and illumination control to decentralization, networking and intelligence.

The combination of intelligent lighting control technology with the rapidly developed LED lighting technology will have a great impact on lighting products and lighting engineering applications. Meanwhile, the illumination energy conservation also develops from light source energy conservation, lamp controller and other parts energy conservation and lamp energy conservation to illumination engineering intelligent management energy conservation with more obvious energy-saving effect, which can generate great promotion effect on the development of the illumination industry.

With the gradual coming of the information age, the IOT internet of things is gradually improved, a perfect way is provided for the storage and transmission of information, the sensing technology is an important component of the internet of things, and the construction of the sensing technology becomes the key for the construction of the internet of things. The sensor network is formed by a plurality of micro sensor nodes in a wireless or wired networking mode, so that information can be stored and transmitted by groups, different application effects are achieved, application experience in the intelligent application field of the sensing technology is improved, and a self-adaptive intelligent sensing effect is generated.

Usually, the sensor technology network is implemented in the following ways: 1) and carrying out networking control in a wireless mode (such as 2.4G, wifi, Bluetooth and the like). 2) A wired networking mode is adopted, and one inductor controls a plurality of lamps to be networked in a wired mode. 3) And networking is performed by adopting a wired DALI bus through a DALI addressable lighting interface system.

The control mode of wireless networking is adopted, and the communication among groups is realized by using mainstream control signals such as mainstream 2.4G, wifi and Bluetooth, the mode of wireless networking is relatively convenient, the control mode of a master machine and a slave machine can be defined in a design by a software algorithm, the positions of master lamps and slave lamps are randomly defined in application, but due to the uncertainty of wireless space propagation, the environmental interference is large, the situations of data packet drop or crash are easy to occur, and the stability is poor.

Adopt wired mode, through a plurality of lamps of inductor control, this kind of wiring degree of difficulty is than higher, and the response contact is only one, and the response scope is narrower, and user experience effect is relatively poor, and later maintenance is more difficult moreover, needs reinstallation if the response contact position changes.

The method adopts a wired DALI bus, carries out networking through a DALI addressable lighting interface system, and mainly comprises the following two realization modes at present:

(1) an off-line DALI sensor, which uses an AC input mode to output DALI signals to control a plurality of LED DALI power supplies and provide power supply for a DALI network, is advantageous in that it can operate off-line without an additional PS power supply or DALI host as shown in fig. 5. The defects that grouping control cannot be carried out, the DALI host and the lamps cannot be simultaneously accessed into a DALI network, grouping setting of the lamps cannot be carried out, only one inductor can be arranged in the same network, an induction blind area is large, and actual installation requirements cannot be conveniently met.

(2) The DC type online DALI inductor adopts a DC input mode, supplies power to the inductor through a DALI bus, outputs a control signal by the DALI inductor, and supplies power supply of the DALI bus by a PS power supply or a DALI host. The wiring diagram is shown in fig. 6, which overcomes the defects of an off-line DALI sensor, the DALI host can be used for setting the DALI sensors in groups, and a plurality of DALI controllers can be accessed into one network to realize a plurality of contacts, so that the sensing blind area is greatly reduced. However, since the inductor is powered by the DALI bus, the inductor consumes a significant amount of current in the DALI network, since a standard PS power supply or DALI master can typically only supply around 200mA of current, each DALI power supply consumes around 3mA, and normally a network can be connected to 64 lamps for a total current consumption of 192 mA. And the DALI sensors normally consume about 30mA, and according to the standard, when 1 DALI sensor is accessed, one network can only be connected with 54PCS power supplies at most, 2 DALI sensors can only be accessed with 44PCS power supplies, so that 5 DALI sensors can also be accessed in one network at most, and at the moment, about 15 DALI power supplies can only be accessed. However, according to the characteristics of the DALI network, a DALI network can be divided into 16 independent groups, and this function is greatly castrated, and the main advantages of DALI are not fully realized.

From the above, it can be seen that there are not small drawbacks when using DC type online DALI inductors: DALI sensors are limited by the DALI sense bus current and are not convenient to use. Accordingly, one skilled in the art provides a DALI addressable smart sensor control system to solve the problems set forth in the background above.
