Description
Technical Field
The invention relates to the field of smart city lighting, in particular to a smart city lighting ecosystem.
Background
The urban landscape lamp can reflect historical interest of a city, and meanwhile, the elements of the city, such as the humanity, the national features, the historical culture and the like, provide rich design materials for landscape lighting. In order to integrate landscape lighting into cities, and into human lives, it is necessary to design urban landscape lighting systems that conform to different cities.
The overall overview of the development trajectory of urban lighting control can be summarized in three major stages.
In the first stage, the main characteristics of the lighting control of the city are as follows: the traditional strong current circuit switch is used as an execution effect, and the automatic control of a single lamp or a local area is used as an execution mode. The main representative scheme takes clock timing switch control, light sensing loop control and PLC loop control as main marks. The control defects of the traditional control mode are obvious, for example, the control cannot be systematized, the control cannot be linked, the effective and simple real-time operation cannot be realized, and once the lighting state is set, the modification must be carried out one by one, which wastes time and labor. In addition, the working state of the field lighting equipment can not be fed back at all, and the field lighting equipment can not be monitored conveniently and effectively;
in order to overcome the problems, the urban lighting control is rapidly developed and enters a second stage, remote control is taken as a main function representative in the second stage, and the remote control of the tail-end lighting equipment is realized by linking the tail-end lighting equipment to the Internet through media such as a GPRS network, a 3G network and power line carrier waves of the tail-end lighting equipment; the control solves the problem that the first stage of urban lighting control is more prominent to a great extent, and the urban lighting equipment can complete the lighting control function of the first stage under the condition of reducing manpower patrol to the maximum extent. The control scene that can realize still is more single at this moment, and the richness of scene content itself is also pale, and the urban lighting control system protocol and the interface of this stage do not have unified standard, and the construction is also respectively for government, and construction standard and standard are also disorderly and unordered, and do not rise to the height of city management from the management and control theory yet.
In addition, the standardization of the whole market is still insufficient in the second development stage, and the problems of equipment type selection in the construction design process are firstly shown, a lot of design and implementation units move industrial control modules or indoor lighting control schemes to the outdoor lighting control field, move street lamp RTU management modes to the landscape lighting field, and the problems that the stability is extremely poor due to different use environments, the expected effect cannot be achieved due to single function, and the like are caused, so that the later-stage equipment operation and maintenance are difficult. Various field data acquisition and monitoring information feedback are also seriously lost; secondly, on the aspect of electrical design problems in the re-construction process, a plurality of electrical designs have serious unreasonable design problems, for example, the problems that the subsequent loop control is regular and difficult due to excessive control loop design, the power consumption safety capacity value of the distribution box is designed to ignore the power mutation of media and the like; secondly, the disorder of on-site electric box configuration wiring is also brought by the non-standardization of a plurality of electrical designs, and the problem of later-stage operation maintenance parties is more caused because the construction party identifies the line sign less strictly for own convenience. In addition, various problems exist in the aspects of construction and lamp production, firstly, due to the quality problem of constructors, a construction unit cannot completely ensure that wiring is finished according to an electric system diagram, and the phenomenon of private connection and disorderly connection occurs, and further, the non-specification of the construction process brings about a plurality of potential problems. In addition, lamp manufacturers often have certain technical barriers, which causes the color, the line diameter and the like of the signal line not to follow the national standard, and brings technical barriers for unified linkage control.
Therefore, the development of the urban lighting control market in this period is not only greatly disordered, but also cannot be calculated at the urban level, and further cannot realize urban intelligent management. In the development process at this stage, another change can be seen, that is, the controlled object of urban lighting has also happened progressive change silently, which is mainly expressed in the development trend of 'stage' of urban night scene in addition to the traditional lighting requirement, wherein laser, light show deduction, LED multimedia dynamic deduction and interactive light are used as a salient representation, at this time, the original simple scene composition and scene control are not conscious from the realization mode or from the intelligent control, and the following complex scene management and linkage requirement continue to catalyze the forward development of the whole industry.
Based on the contradiction in the development of the second stage of urban lighting control, the urban lighting control quickly enters the third stage of intelligent control management, and the control requirements of the current stage of the urban manager are mainly reflected in three aspects; firstly, carrying out a first treatment; network information security, second; the operation is stable. Thirdly, performing secondary filtration; intelligent control and fine management. The intelligent control of the urban landscape lighting at the stage is based on the intelligent management of a new generation communication technology combined with the Internet and the Internet of things, and the intelligent management covers a plurality of characteristics such as large-area linkage control, wide multi-unit access, gorgeous and colorful scene deduction performance and the like. At the moment, the urban illumination control management gets rid of the traditional strong current circuit switch early, and is richer in accessing weak current animation deduction, street lamp illumination adaptive self-adjustment, autonomous offline operation after network abnormity, mobile remote interconnection control, illumination scene linkage switching flexibility and real-time monitoring of a rear-end platform.
The pleasible progress of the third stage is seen, the problem of the third stage also has the special points of different first two stages, due to the rapid disordered development of the second stage, the disorder of interfaces and protocols of different controlled lighting devices is caused, and the disorder also buries a great hidden danger for the development of the third stage of urban lighting control. Besides the problem of compatibility upgrading caused by the development of the second stage, the urban lighting has integration difficulty in the development process of the third stage; in addition, under the large background of wide access to the internet and the internet of things, the development of the third stage also has the outstanding problem, and the obvious problem is the potential safety hazard caused by high dependence on the internet.

Such a differentiated information amount is very huge in a city unit area, and is different from a show, a scene or a street, which is a union of a plurality of such shows, scenes or streets.

Several application examples are provided below
Example 1
Intelligent lighting control application scheme
Intelligence lighting control equipment is given first place to functional illumination, requires that lighting equipment has characteristics like: the system has the advantages of uniform load loop management capability and real-time monitoring capability of the working state of single-lamp equipment, and in addition, the system also provides scene requirements with great differentiation for different application scenes, such as landscape lighting scene requirements, indoor lighting scene requirements or street lamp lighting scene requirements, in addition to the control of the lighting equipment. The mainstream of lighting control in the current market still mainly adopts power carrier communication and GPRS, and the communication bandwidth and the communication stability are greatly limited. Newly arising 5G and NB-IoT have been greatly developed in recent years, and NB-IoT is a new narrowband cellular communication (LPWAN long distance communication technology) proposed in the 3GPP standards organization in 2015 and 9 months, and is an innovative technology, and is a narrowband internet of things technology based on a cellular network defined by 3 GPP. The intelligent lighting system has the inherent advantages of deep coverage capability, low power consumption, low operation and maintenance cost, and is very suitable for the intelligent lighting field of smart cities; in addition, optical fiber and Ethernet communication are commonly used, the traditional construction mode which simply depends on public network is also broken away among network nodes, more special physical networks can be used for safety, and the basic network foundation and the important safety foundation can be provided for constructing an intelligent lighting control network. The importance of the solution of the system application architecture is naturally highlighted when the network basis and the security basis of the intelligent lighting control are both based on the original basis, since this is an important ring for the flexible and efficient operation of the system. All links are distributed in a star shape by taking a cloud platform as a core point, and in an intelligent lighting control center, the biggest difference between the cloud platform and the conventional control center is that the intelligent lighting control center requires a system to have better human-computer interaction, more flexible and rich application scene setting, strict hierarchical application management authority setting and flexible combination capability with linkage and independence; powerful systems also require the intelligent control center to be able to master the working state, abnormal alarm and real-time picture monitoring of the on-site controlled facilities in real time. The cloud platform can periodically provide data reports of system operation, comprehensive multi-node multi-index evaluation can be performed on the operation condition of the system, and the reliability and the predictability of the system operation are ensured.
According to the technical requirements of the intelligent lighting control center, in a framework which relies on a cloud platform as a core node, all terminal intelligent lighting controllers can be linked to the cloud platform through optical fibers, Ethernet, 4G or NB-IoT. The intelligent lighting controller is required to be capable of being connected with various general sensors, such as GPS geographic coordinate sensing, illumination intensity sensing, abnormal door opening and closing sensing, temperature sensing, video transmission and the like, the intelligent lighting controller conducts primary collection and processing on the data, then the data, the circuit opening and closing state, electric energy information and the like are transmitted to the cloud platform through a network connected with the cloud platform, and then the cloud platform conducts deep processing and integration on the data.
Except the intelligent lighting control center, the mobile control terminal can be openly accessed to the cloud platform, the mobile control terminal takes a tablet personal computer and a smart phone as main carriers, field debugging control or one-button linkage control and the like which are separated from the control center can be realized, temporary timeliness control during visitors watching and visiting is realized, the original simple centralization principle is separated from the control mode, and the control is more flexible and more applicable.
Example 2
Multimedia screen and landscape brightening control application scheme
The multimedia screen and the landscape brightening control are characterized in that the multimedia screen is subject illumination of the brightening control and is in the main status of the whole brightening illumination control, and basic illumination and functional illumination matched with the multimedia screen can be matched and set off the effect of the main illumination to the maximum extent, so that the framework of the system needs to have stronger coordination and linkage capacity of an operation processing unit of the system besides a server group, a node end industrial personal computer, an LED controller and the like which are more than those of a pure illumination control system.
Different ordinary basic illumination or function illumination, the multi-media screen needs to control a large amount of pixel points, pixel lamp strips, and the serial shift communication of SPI and the DMX protocol of the extension type are commonly used at present. Brands based on PC software such as; the MADRIX, Visual, Sunlite, Chromatec and the like are applied to respective subdivision fields, and domestic brands such as Mingrui, Yuming Xin and the like are provided. Most LED terminal controller manufacturers in the market adopt a 'variant' DMX512 protocol, and control equipment and lamp protocols self-defined by international brands, such as Philips and Oselan, also appear as non-standard protocols; these products and brands are the major product sources for multimedia screen designs. At present, the great application of the domestic landscape brightening LED pixel lamp is realized, and the Artnet, the ACN and the like based on the TCP/IP are supplemented to the application protocol so as to increase the larger control capacity. The domestic technology of the LED control system software and hardware completely surpasses foreign products; the method has the characteristics that the hardware volume is small, the software function is complete, the method gradually becomes the mainstream of the market, and the method also opens wider space for the design of future multimedia screens.
The multimedia screen generally uses a special physical network due to the safety consideration of application, and the 4G type wireless network also uses a special VPN network channel, so the basic characteristic of the network architecture is that the private network is special, and the interference or the intrusion from an external network is avoided. The server group of the whole network can be arranged near the location of a project, a master control room realizes real-time supervision and operation of the whole system, and in order to ensure the time difference problem when a terminal node industrial personal computer and a matrix intelligent control terminal are linked, terminal network nodes are provided with additional time service devices so as to ensure the clock synchronization of each terminal unit in the whole system; in addition, linkage backup is carried out in linkage performance so as to avoid temporary runaway caused by sudden disconnection of the terminal equipment. The network connection in the theme show is not limited to 4G networks only, but ethernet and fiber optics are also optional. In the theme lighting part, the node end industrial personal computers of heavy current loop management and control and performance effect control operate independently respectively, but are linked and controlled in a server group through a system unified 'one-key', the heavy current loop management and control is responsible for power supply and power safety management, the node end industrial personal computers are responsible for performance effect performance, and the two operate synchronously under the coordination of a master control room server to finish effect performance. The basic lighting part does not have deduction animation, so that strong current circuit control and tail end monitoring are completed only through a matrix intelligent control terminal; besides basic loop control and end monitoring capabilities, the functional lighting part also needs to have single-lamp dimming, color mixing functions and the like.
The linkage management of the theme lighting, the basic lighting and the function lighting is uniformly coordinated and finished by the server group, and the linkage centralized control of the areas is required to be finished. The master control room can realize good man-machine interaction besides the comprehensive monitoring and operation management capabilities of the project and portable transplantation of partial control functions, and through the portable function transplantation, the on-site management and control and linkage operation can be more convenient and fast, and the on-site linkage control is convenient. In addition, the stability of the system is also required, the stability of the system operation is mainly ensured through two aspects, on one hand, the standard limit value of equipment strictly selected in the process of system architecture must be higher than or equal to the industrial grade requirement, on the other hand, the construction of a special network creates a good intranet environment for the stability of the system, and the existence of possible interference elements is avoided.
Example 3
Lamplight brightening control scheme
The lamplight show is mainly formed by depending on a large-scale outdoor place, a beautiful natural landscape or a large-scale building group to cooperate with various projection animation deductions or picture projection of a large-scale projector, the effect scene is converged by cooperating with an acousto-optic and electric technology, and in addition, various laser performance effects, holographic projection, adjustable elements such as a music fountain, a large-scale outdoor screen, an LED spliced screen and the like are matched, so that a brand new city night scene is created in an all-dimensional and multi-angle mode, and the beautiful city night sky is dressed up.
In order to realize the light show effect in a matching manner, the brightening management system needs to organically combine remote monitoring, intelligent illumination control technology, multimedia demonstration technology and light show art, adopts the method of combining optical fiber + Ethernet +4G wireless network networking, centralized control and edge control, and ensures that each essential point of a site is monitored in real time and each scene is refined and soft in deduction and switching among scenes by means of strong cloud processing capability.
The core of the light show control system is centralized in a multimedia light control platform and an intelligent control cabinet, wherein the intelligent control cabinet is a main control device at the site of the tail end, the unified coordination management of various light show elements at the site is completed, information is fed back to the control platform, the intelligent control cabinet is required to be compatible with various communication protocols TCP/IP, Art-net, ACN, RDM, DMX512 and the like, and the wide access of the tail end show elements including a special effect lamp, a laser lamp, a projection lamp, a music fountain and the like is realized. A multimedia light control platform in the system is connected with an intelligent control cabinet through optical fibers (DMX 512& RDM & Art-Net) to form a communication network, information transmission such as control instructions, field effect animation and terminal information feedback is completed, in addition, a high-definition camera transmits video information to the intelligent control cabinet through an RTP protocol, and then the video information is fed back to the light control platform, so that remote real-time video monitoring is realized. The multimedia control platform in the system outputs video and audio information to the outside, the video and audio information respectively reaches the sound system and the video server, and the video and audio information are decoded and played by allocating the video server and the sound system, so that the linkage deduction of sound effect animation and the like is completed.
In the light show control system, a portable mobile control carrier is additionally arranged for facilitating early debugging and testing of projects, a tablet personal computer is mainly used, and each element of the light show projects can be flexibly controlled and controlled in an area linkage mode through the portable control interface, so that the initial debugging of the projects is efficient and convenient. In addition, regional linkage control and one-button triggering operation can be realized when the scene is deduced, so that the whole light show project has more concise and efficient operation and monitoring experience.
