In order to facilitate timely finding of the problem, it is preferable that S3 further includes: and S4, monitoring the display condition of the video playing picture and the presentation condition of the lighting equipment, generating a monitoring text material and outputting the monitoring text material to the management terminal. As shown in fig. 3, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs include light control instructions and video playing pictures; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; s3, displaying video playing pictures on the media vertical surface, and synchronously adopting a light control instruction to control light equipment; and S4, monitoring the display condition of the video playing picture and the presentation condition of the lighting equipment, generating a monitoring text material and outputting the monitoring text material to the management terminal. For example, the display state of a video playing picture and the presentation state of lighting equipment are monitored to obtain monitoring video data, a caption extracting mode and the on-off state of the lighting equipment are adopted to generate monitoring text materials, and the monitoring text materials are output to a management terminal. Or, intelligently identifying video playing pictures and converting the video playing pictures into a keyword mode and a synchronous on-off state of lighting equipment to generate monitoring text materials, and outputting the monitoring text materials to the management terminal. Therefore, problems can be found and treated in time when the problems occur; and because the characters are used as materials, the transmission speed is high, the system overhead is low, and the energy consumption can be saved.
In order to prompt the administrator, preferably, in S4, the display status and the presentation status are compared to determine whether the synchronization between the display status and the presentation status is abnormal, and when the synchronization is abnormal, a warning signal is output to the management terminal. As shown in fig. 4, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs include light control instructions and video playing pictures; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; s3, displaying video playing pictures on the media vertical surface, and synchronously adopting a light control instruction to control light equipment; and S4, monitoring the display condition of the video playing picture and the presentation condition of the lighting equipment, generating a monitoring text material, outputting the monitoring text material to the management terminal, comparing the display condition with the presentation condition, judging whether the synchronism of the display condition and the presentation condition is abnormal or not, and outputting a warning signal to the management terminal when the synchronism is abnormal. For example, comparing the display condition with the presentation condition, and determining whether the synchronicity of the two conditions is abnormal according to predefined trigger conditions, wherein the predefined trigger conditions include, but are not limited to, picture comparison, letter comparison, voice matching, light triggering and the like. Therefore, whether the display condition and the presentation condition are abnormal or not can be simply and automatically judged, namely whether the synchronism of the video playing picture and the lighting equipment is abnormal or not can be judged, and once the abnormality occurs, the management terminal is immediately informed. The management terminal includes but is not limited to a computer terminal and a mobile phone terminal. So that problems can be quickly discovered, notified in place, and then resolved.
To simplify the control, it is preferable that the light control command and the video play picture are packaged in a file of one program in S1. As shown in fig. 5, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs comprise light control instructions and video playing pictures, and the light control instructions and the video playing pictures are packaged in a program file; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; and S3, displaying video playing pictures on the media vertical surface, and synchronously controlling lighting equipment by adopting a lighting control instruction. That is, a program file can simultaneously have a light control instruction and a video playing picture, which is designed for convenient control and simplified control, so that time synchronization can be conveniently realized, and data processing can be conveniently carried out in a data center, and then the data is transmitted to a remote playing position, such as a position outside thousands of miles, namely a landscape lighting position, to respectively control a media facade and a light device to synchronously output, wherein the media facade comprises but is not limited to a building outer wall or a vertical display surface and the like provided with an LED display screen or decorative lighting; light fixtures include, but are not limited to, light bars, light strings, light strips, light points, modules, and the like.
In order to avoid the problem of synchronization error in the file arrangement process, it is preferable that in S1, the light control command and the video playing picture are clock-synchronized. As shown in fig. 6, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs comprise light control instructions and video playing pictures, the light control instructions and the video playing pictures are packaged in a program file, and the light control instructions and the video playing pictures are subjected to clock synchronization; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; s3, displaying video playing pictures on the media vertical surface, and synchronously adopting a light control instruction to control light equipment; and S4, monitoring the display condition of the video playing picture and the presentation condition of the lighting equipment, generating a monitoring text material, outputting the monitoring text material to the management terminal, comparing the display condition with the presentation condition, judging whether the synchronism of the display condition and the presentation condition is abnormal or not, and outputting a warning signal to the management terminal when the synchronism is abnormal. Clock synchronization is an important function because the light deductive program is scheduled at a position which may be far away from the landscape site, and the data remote transmission amplifies the error or error times, so that the one-quarter error may be amplified and presented infinitely, and landscape lighting ultra-large programs are mixed and thus are less error-tolerant, and once the error often involves huge economic loss or claim, clock synchronization is very necessary and very important.
To avoid errors, it is preferable that the light deductive program is uniformly programmed using a unique control device in S1. As shown in fig. 7, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging the light deductive programs by using the only control equipment, wherein the programs comprise light control instructions and video playing pictures, and the light control instructions and the video playing pictures are packaged in a program file; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; and S3, displaying video playing pictures on the media vertical surface, and synchronously controlling lighting equipment by adopting a lighting control instruction. That is, for the same program, only one unique control device is used to uniformly schedule a specific light deduction, which is similar to the previous embodiment, mainly to ensure data accuracy and avoid errors; but also has the advantage of flexible programming in the early stage.
In order to improve the data accuracy and ensure the synchronization effect, it is preferable that in S2, the video playing picture of each frame corresponds to or includes a light control command. As shown in fig. 8, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs include light control instructions and video playing pictures; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device, the video playing picture of each frame corresponds to the light control instruction or contains the light control instruction; and S3, displaying video playing pictures on the media vertical surface, and synchronously controlling lighting equipment by adopting a lighting control instruction. For example, the light control instructions are uniformly output by the animation output equipment, and the light control instructions realize the DMX console function and are synchronous and accurate to frames. Because the control of the media facade tends to have higher complexity compared with the control mode of the lighting equipment, under the guidance of the principle described in the foregoing embodiment, the embodiment shown in fig. 8 above can also be used alone, or the embodiment shown in fig. 8 and the foregoing embodiment are combined together to be used as the landscape lighting ultra-large program mixing method. The series of embodiments all have a common goal of improving the synchronization accuracy, which is an important technical problem to be solved by the present invention.
In order to design the fault-tolerant correcting way, preferably, in S3, when the lighting equipment is controlled by the lighting control command synchronously, the method further includes the steps of: insert or modify light control instructions. As shown in fig. 9, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs include light control instructions and video playing pictures; s2, the animation output device analyzes the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; and S3, displaying video playing pictures on the media vertical surface, synchronously controlling lighting equipment by adopting the lighting control command, and inserting or modifying the lighting control command. Therefore, when the light control instruction is wrong or the light control instruction does not meet the requirement of a video playing picture, a certain degree of freedom is given to workers, and the workers can insert or modify the light control instruction on site or remotely.
Preferably, in S2, the animation output device parses each frame of the program. As shown in fig. 10, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging programs with light deduction, wherein the programs include light control instructions and video playing pictures; s2, the animation output device analyzes each frame of the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the light device; and S3, displaying video playing pictures on the media vertical surface, and synchronously controlling lighting equipment by adopting a lighting control instruction. That is to say, the landscape lighting ultra-large program mixing arrangement method of the invention accurately controls each frame synchronization, which is also the key point of the invention, integrates various animations and control signals into a complete program file, such as arrangement/analysis by general or special equipment or software, unified control, simplifying the program arrangement process, solving the problem of coordination and synchronization between equipment, greatly reducing the labor and hardware cost, and effectively improving the working efficiency.
As shown in fig. 11, an embodiment of the present invention is a landscape lighting super-large program mixing method, which includes the following steps: s1, uniformly arranging the light deductive programs including the light control instruction and the video playing picture by using the unique control equipment, packaging the light control instruction and the video playing picture in a program file, and carrying out clock synchronization on the light control instruction and the video playing picture; s2, the animation output device analyzes each frame of the program, outputs the video playing picture to the media vertical surface, and outputs the light control instruction to the lighting device, and the video playing picture of each frame corresponds to or contains the light control instruction; s3, displaying video playing pictures on the media vertical surface, synchronously adopting a light control instruction to control light equipment, and inserting or modifying the light control instruction; and S4, monitoring the display condition of the video playing picture and the presentation condition of the lighting equipment, generating a monitoring text material, outputting the monitoring text material to the management terminal, comparing the display condition with the presentation condition, judging whether the synchronism of the display condition and the presentation condition is abnormal or not, and outputting a warning signal to the management terminal when the synchronism is abnormal. And so on. For example, in S2, the video playing picture and the light control command are both transmitted using UDP messages, so that the method is applicable to PC devices or lightweight embedded devices, and for remote data transmission, a data encryption algorithm and a data verification algorithm may be used to perform security control of data transmission.
For example, designers can uniformly arrange the light deduction programs, uniform control equipment can be used for uniformly arranging the light deduction programs, and animation and light control instructions are packaged in a program file to be uniformly arranged, so that the program arrangement is more flexible and accurate; the animation output equipment analyzes each frame of the program, and each frame of picture can contain a light control instruction; the pictures are output to the media vertical face, the light control instructions are output to the lighting equipment, the animation and the lighting effect are completely synchronous, the complete lighting show is presented, the light control instructions can be inserted or modified in the program deduction process, and the animation output equipment can be animation software or special software operated on a common PC (personal computer), or can be embedded equipment which is independently developed and the like.
For very large presentation systems, the media facade may comprise a plurality of building facades forming a cluster of nodes, each building facade acting as a node, i.e. a display node, comprising several light points, e.g. thousands or more; the node cluster of media facades includes N building facades, N being a natural number greater than 1, for example N includes but is not limited to 2, 10, 87, 100, 1000, and the like. In order to ensure the quality of mixed playing of landscape lighting ultra-large programs, when the media facade displays a video playing picture, the monitoring of the node cluster of the media facade needs to be realized, or in S3, the monitoring of the node cluster of the media facade needs to be realized. For example, S3 further includes: s31, each building facade of the landscape lighting is respectively used as a node, and each node is connected with a control device in advance; s32, the control equipment of all the nodes respectively compress and pack the picture data output to the corresponding building facade to obtain the compressed data of each node; s33, the control equipment of all nodes adopts a user datagram protocol packet mode to return the compressed data to the server in real time; s34, decompressing each compressed data by the server to obtain picture data, and outputting the picture data of all the nodes to a master control large screen in real time; and S35, monitoring the display picture of the master control large screen in real time, and processing when abnormality occurs. That is to say, all node control equipment compress and pack the picture that is output to the building facade dynamically, and all nodes pass through self-defined network transmission protocol, adopt user datagram protocol subcontracting mode, return the picture back server in real time, and the server decompresses the data, outputs all node pictures to total accuse large-size screen in real time, and the large-size screen can set up the node number of show wantonly, the picture size, fortune dimension personnel real-time supervision picture data, makes necessary response when unusual. Therefore, all the nodes in the cluster are synchronously returned in real time through each node for optimally designing landscape lighting, so that the monitoring efficiency can be improved, the abnormity can be captured at the first time, the occupied bandwidth is reduced, the storage resources are reduced, operation and maintenance personnel can conveniently monitor and quickly respond to the abnormal condition, the network utilization rate is greatly improved, the cost is reduced, and the working efficiency is improved.
Effective monitoring may also be achieved in conjunction with S4. Specifically, there are many anomalies, which are mainly divided into two aspects, namely system failure and content control. The system failure can also be understood as hardware failure or software error, and the content control mainly comprises content runaway, illegal content monitoring and the like. This is to meet the requirements of regulatory legislation and to ensure the rights and interests of the owner from being compromised. For example, in S35, the total control screen is divided into a plurality of display sub-screens, and the screen data of all the nodes are respectively displayed in real time; when the display sub-picture corresponding to one node is selected, the display sub-picture is adjusted according to the adjustable magnification scale and is covered on part or all of other display sub-pictures. Therefore, the problem that multiple nodes cannot synchronously observe in the existing scheme is solved. For example, in S35, the total screen is divided into a plurality of display scales, each display scale corresponds to a different number of display sub-screens, and when any one display scale is selected, the corresponding number of display sub-screens are displayed according to the selected display scale. Therefore, the important view of the management and control personnel for displaying the sub-pictures can be realized. For example, the picture data of each node is sequentially displayed in a first-in first-out manner according to the selected display scale according to the node sequence number of each building facade of landscape lighting. Therefore, different quantities of display pictures can be realized, the picture data of each node can be displayed more clearly, and management and control personnel or AI program monitoring is facilitated.
A landscape lighting system, also referred to as landscape lighting system, may have a plurality of building facades, each of which may have a plurality of lighting sources, such as LED lighting modules or LED point sources. A building vertical face and all the lighting sources thereof are taken as a node, and all the building vertical faces illuminated by the landscape are respectively and independently taken as a node. A control device is provided for each node individually, often in the building in which the building facade is located. Preferably, for two adjacent building facades, if the distance between the two adjacent building facades is judged to be smaller than the special distance, two nodes corresponding to the two building facades are connected with the same control device in advance, and the two nodes can belong to the same landscape lighting system, namely a landscape lighting system, and also can belong to two different landscape lighting systems; similarly, for a plurality of adjacent building facades, if the radius of the circle where the building facades are located is judged to be smaller than the special distance, each node corresponding to the building facades is connected with the same control device in advance, and the nodes can belong to the same landscape lighting system, namely a landscape lighting system, and also belong to a plurality of different landscape lighting systems. That is to say, when a building has two building facades to be used in the same or different landscape lighting systems respectively, the two nodes can be connected with the same control device, so that not only is the cost saved, but also the occupation of the field can be reduced, and therefore, the competitiveness of the product can be improved, and the application is facilitated.
The control device of each node outputs its own picture data to the building facade, dynamically compresses and packages the picture data as compressed data of the node, and the compressed data can be encrypted or not. Preferably, the control device of each node dynamically compresses and packs the picture data output to the corresponding building facade in a rolling frame mode to obtain compressed data of each node; the Frame rolling mode is that a certain number of frames (Frame) are taken in a first-in first-out (FIFO, FirS3t Input FirS3t Output) sequence, and the dynamic compression packing is that a certain number of frames are compressed and packed each time; the certain number is the number of frames of the preset value, and each frame is a piece of picture data output to the corresponding building facade. For example, the number is 1, 2, 3, 4 or 5, that is, the number of frames is 1 frame, 2 frames, 3 frames, 4 frames or 5 frames; preferably, the certain number is a set of two or three natural numbers, which is not a constant number but a random number, and in this case, the rolling frame mode is a frame in which the picture data output to the corresponding building facade are sequentially taken as random numbers in a first-in first-out mode, and the random numbers are selected from 1 and 2, or the random numbers are selected from 2 and 3, or the random numbers are selected from 1, 2, 3, 4 and 5; and so on. This is to simplify the amount of computation and data, and provide some ways to compensate for the unreliability of the data, and in the following steps, the compressed data received by the server is regular and approximately in a multiple relationship. Therefore, the calculation amount of the control equipment at the node can be simplified, some redundant data are provided for the server, and the defects that a user Datagram Protocol (UDP, US3er Datagram Protocol) is too simple and the data is unreliable are overcome; the invention totally adopts UDP messages for transmission, is suitable for being implemented by PC equipment or lightweight embedded equipment, and simultaneously occupies less bandwidth and storage resources compared with the prior art under the condition of the same number of nodes.
And a master control large screen is adopted to simultaneously display the picture data of a plurality of nodes or simultaneously display the picture data of all the nodes. The simultaneous display of the main control large screen is necessary, the number of monitoring personnel or the number of monitoring equipment can be reduced, and therefore the cost of the whole system is reduced. Preferably, in S34, the server outputs the picture data of all the nodes to the main control large screen in real time according to the time point; for example, the time point is 5 seconds to 60 seconds or more before the display, such as 5 seconds to 300 seconds, preferably, in S32, the control devices of all nodes respectively output the picture data to the corresponding building facade, and perform dynamic compression and packaging in advance to obtain the compressed data of each node; for example, dynamic compression packaging is performed 5 seconds to 60 seconds ahead or 5 seconds to 300 seconds ahead, that is, 5 seconds to 60 seconds ahead of the building facade display, the display data are sent to the server, in S34, the server outputs the picture data of all the nodes to the total control large screen in real time according to the time points, at this time, the total control large screen displays the picture data of each node at a future time point, unless the picture data is played in real time, the monitoring personnel can find problems in advance, give control, for example, the node with problems will be played, and the content to be played will be switched to a predetermined advertisement or other pictures.
To implement data transmission, for example, S31 may be preceded by: and S30, respectively establishing network connection and presetting a network protocol for each building facade of the landscape lighting. Preferably, the number of the synchronous backhaul nodes is set to be unlimited in the preset network protocol. The specific network connection mode and the setting of the network protocol are set according to the conventional setting.
In order to ensure the normal operation of the whole system, for example, the landscape lighting ultra-large program mixing arrangement method of the present invention needs to perform operation debugging before uniformly arranging the light deductive program or before displaying the video playing picture on the media facade, for example, in S31, each node is pre-connected to a control device, or in S30, network connections are respectively established for each building facade of landscape lighting, or before S1, the landscape lighting ultra-large program mixing arrangement method further includes a step of detecting a point light source structure diagram of the building facade for maintenance; the method specifically comprises the following steps: s301, building a wireless network so that the handheld device is connected with the control device through a communication medium; s302, operating the handheld device in front of the building facade, controlling the control device, and lighting a point light source appointed on the building facade; s303, recording the port of the controller where the current point light source is located, the serial number of the lamp point and the coordinate of the current point light source corresponding to the building facade; s304, returning to execute the S302 until all the point light source detection records are finished; s305, drawing a point light source structure diagram. Therefore, the operation and maintenance debugging process can be optimized, the human resources can be saved, the operation and maintenance debugging work is simplified, the whole process is convenient to operate, and the debugging efficiency of debugging personnel can be improved; and many steps can be realized by combining an automatic technical means, so that the operation and maintenance debugging of a large-scale landscape lighting system, particularly an ultra-large-scale landscape lighting system, is greatly simplified, a large amount of repeated labor consuming manual labor or communication of two rushing places is simplified into one handheld device, and compared with the prior art, the operation and maintenance debugging of the ultra-large-scale landscape lighting system is greatly facilitated.
For example, in S301, the wireless network uses the internet, radio, wifi, 4G or 5G for data transmission. The invention is the biggest difference from the prior art, the communication medium can be a router, a signal repeater, a remote server, or two routers connected by wire, and the like, because the debugging and testing personnel operating the handheld device in front of the building have a certain distance with the position of the control device, such as a machine room, which is often hundreds of meters or even thousands of meters, under the condition, the wireless network must adopt the communication medium to realize the connection between the handheld device and the control device, which is a blind area of wireless connection, and the prior technical personnel cannot realize the connection but cannot realize the connection due to the limited self-capability of the wireless connection. Preferably, S301 further includes that the control device is provided with a built-in wireless communication module, encapsulates the display data for debugging to form a data packet, and opens the protocol control command. Preferably, all the display data are encapsulated in the control device to form a data packet; and when the control device is controlled in S302, that is, when a control instruction is received, the control device sends a display data frame in the form of a data packet to light up a designated point light source connected to a corresponding controller port on the building facade. Preferably, the protocol control command forms a command combination and has a simplified command identifier, and the control device sends a display data frame in the form of a data packet according to the command combination when receiving the command identifier, and lights a designated point light source connected to a corresponding controller port on the building facade. In this way, by combining the instruction identification or the control instruction or the combination thereof with the data volume of not more than 30 bytes in other embodiments, the operation of operating the handheld device in front of the building construction can be greatly simplified, thereby simplifying the specific mode of controlling the control device and improving the debugging efficiency.
The handheld device is also a handheld terminal, and can be a mobile phone, a tablet, a notebook computer and the like, and the handheld device is wirelessly connected with the control device through a communication medium, so that the application is convenient, and the control is very convenient. The LED lamp can be used as a point light source, a plurality of point light sources, a module or a lamp string. From the perspective of improving efficiency, only one point light source is basically not made at a time, because the ultra-large landscape lighting device can have hundreds of thousands or millions of point light sources; therefore, the light sources are usually grouped at a time, for example, all the light sources connected in series to the same port are simultaneously lighted, so that in other embodiments, the serial number of the light source, that is, the lamp point, needs to be recorded so as to be accurately identified during maintenance. For example, the operation of APP in the handheld device in front of the building construction is also included in S302. That is, the mobile phone can be used for controlling, and the APP of the mobile phone can also be used for controlling; preferably, the APP can also be controlled by voice. Preferably, in S302, the control device is controlled by the handheld device, and a control instruction or a combination thereof is sent to the control device, where the data size is not higher than 30 bytes; for example, the handheld device sends an instruction identifier to the control device, and the instruction identifier is used for identifying the instruction combination. Preferably, the data size is not higher than 30 bytes by using basic or simple control instructions or a combination thereof; preferably, the data amount is not more than 20 bytes. For example, handheld device and automated inspection equipment unite into one, as a whole, for example install automated inspection APP procedure on the cell-phone, join in marriage a support similar to live platform and fix, just can simplify the personnel's of debugging work greatly. This is an important innovative design of the present invention, not only to simplify the connection, but also to simplify the control, and unlike various known control methods, we only transmit a very small amount of control commands, e.g., start playing segment 1, stop, next port, next light point or light string, start playing segment 2 … …; the existing debugging method is to transmit a large amount of display data and complex control instructions, for example, a video or a large number of pictures, what is displayed in what time period in the row and column, and so on. For example, the mobile phone APP receives a control word of a user, converts the control word into a control instruction or a combination of the control instruction and the control instruction or the combination of the control instruction and the control instruction is sent to the control device, and the data volume is not higher than 30 bytes. The small data volume is an important advantage worth emphasizing, the control efficiency can be improved, the transmission efficiency can be improved, and the control equipment can quickly and timely illuminate the designated point light source on the building facade.
The specific recording mode can refer to the previous mode and the implementation mode in the prior art, for example, one port of the controller can be connected with a plurality of LED point light sources in series, so that the port of the controller, namely the port number of the controller, and the serial number of the lamp point of the controller need to be recorded; and for the convenience of presentation, the coordinates of the current point light source corresponding to the building facade are recorded. The current point light source can be a point light source, a plurality of point light sources, a module or a string of lights. After the point light source designated on the building facade is lightened, manual recording or recording in a photographing mode can be carried out, and in cooperation with the repeated cycle of S304, a plurality of photographing records can be automatically superposed as high-pixel pictures by a computer and applied to drawing of S305. Because the pixels of the existing camera can be made very high, the difference between two point light sources with small point distance can be accurately presented when the camera shoots tens of meters or hundreds of meters away, so that the controller port and the lamp point serial number where the current point light source is located and the coordinates corresponding to the building facade can be accurately identified and recorded, for example, the controller port and the lamp point serial number where the current group of point light sources is located and the coordinates corresponding to the building facade are identified and recorded. For example, in S303, a rectangular plane coordinate system is used to record coordinates of the point light source corresponding to the building facade; in practice, for the landscape lighting device arranged in a plane, a plane rectangular coordinate system is preferably adopted; for other layout shapes, besides the plane rectangular coordinate system, other reference systems, such as a circular coordinate system or a space coordinate system, can be adopted according to the layout condition of landscape lighting, and the layout can be set according to actual requirements.
S304 is to operate the handheld device in a circulating way, because the number of the point light sources is large, the human error is possible, and the method is preferably performed by adopting an automatic device, but the cost is relatively higher. In practice, a large amount of work is manually completed, and then the manual work may be slowly converted into automatic recording, so that a survey worker or a construction worker can lay a recording environment on the site, and the automatic recording has the main advantages of low error rate and no fatigue.
For example, in S305, the positions of the point light sources in the point light source structure diagram are drawn in a two-dimensional manner and the numbers of the light points are represented, and the connection combinations of the point light sources in the point light source structure diagram and the connection relationships between the point light sources and the controller ports are drawn in a three-dimensional manner. Preferably, the point light source structure diagram is drawn in a machine-readable form, so that the point light source position in the point light source structure diagram can be read by the target program, and the serial number of the light point, the connection combination of the point light sources and the connection relation between the point light source connection combination and the controller port are reflected during reading. Therefore, when operation and maintenance are needed, for example, when a fault occurs and maintenance is needed, automatic judgment can be realized, and in an ultra-large landscape lighting device with tens of thousands, hundreds of thousands or millions of point light sources, the point light sources needing to be repaired or the controller ports thereof can be quickly determined, which is another maintenance index which cannot be realized in the prior art.
For example, S305 is followed by: s306, disconnecting the wireless network. That is, after the point light source detection recording is finished, the network is disconnected, and the dedicated debugging equipment, the communication medium and the like are recycled.
For example, S305 is followed by: s307, establishing a source tracing graph of the corresponding relation of the position of the point light source, the port of the controller and the serial number of the lamp point. Preferably, the corresponding relationship traceability graph presents the following relationship: operating the handheld device in front of the building facade to control the control device, lighting a designated point light source on the building facade, and recording a controller port where the current point light source is located, a lamp point serial number and coordinates corresponding to the building facade; that is, after recording the controller port where the light source of the current point is located, the serial number of the light point, and the coordinates corresponding to the building facade, then, when drawing the point light source structure chart, the point light source structure chart is considered for future maintenance, a back-stepping proof clue is given to the point light source structure chart recorded by the method, the function of checking to prevent errors can be achieved, the function of quickly tracing when problems occur can be achieved, a solution way is found, and also, responsibility can be defined because very large landscape lighting is often a problem, i.e., a big problem, and is likely to malfunction in large numbers, e.g., thousands of light points go wrong together, in actual use, the advertisement playing function plays an important role in advertisement putting, relates to the problems of multiple aspects and large expense distribution, it is therefore necessary to have clear responsibility to minimize the risk of operation and maintenance debugging, which has never been proposed in the prior art. Preferably, S305 and S307 are performed synchronously.
For example, in S32, the control device of each node compresses the minimum value of the data amount according to the display resolution of the total control large screen to increase the compression ratio. Preferably, the node displays the resolution of the window of the picture content at the local self-adaptive monitoring end, and the minimum value is taken for compression, so that the compression ratio is effectively improved. Improving the compression ratio can help to reduce the transmission data volume, improve the transmission rate and properly reduce the operation cost.
For example, in S33, the control devices of the nodes respectively use the user datagram protocol message for transmission. The UDP packetization mode is a key point of each embodiment of the present invention, which is only provided for illustration, and the control device of each node transmits the compressed data to the server in real time in the UDP packetization mode, because the server is like a parent nest, and the data is like going home, which is called backhaul. The invention solves the problem of the limitation of the number of the traditional ftp postback nodes, and also solves the problem that part of professional equipment does not have common protocols such as ftp and the like or cannot be transmitted due to too high implementation cost.
For example, in S35, the display screen of the main control panel is monitored in real time on the spot or through the mobile phone APP, and when an abnormality occurs, the mobile phone APP is used to connect the control device of the corresponding node in real time to pause or replace the playing. The display picture of the total control large screen is monitored on site or in real time through the mobile phone APP, the mobile phone APP is connected with the control equipment of the corresponding node in real time when the abnormity occurs, the playing is paused or replaced, the display picture of the total control large screen is monitored in real time, and the processing is carried out when the abnormity occurs. For example, the data path formed by the control device, the server and the master control large screen of each node performs encryption check on each transmitted data packet, performs real-time error correction retry in the transmission process to ensure the integrity of data transmission, and encrypts the transmission content by using the MD 5. The pause or the alternative play is mainly used for avoiding the risk of laws and regulations and maintaining the owner rights and interests; the encryption can avoid the illegal invasion of hackers or malicious persons, that is, the data path carries out encryption verification on each data packet, error correction retry can be carried out in real time in the transmission process, the integrity of data transmission is ensured, and the transmission content is encrypted by MD5, so that the information safety is ensured.
