Example 1
As shown in fig. 1, the present application provides a stability testing method of a landscape lighting control system, the method being applied to a stability testing system, the method comprising:
step S100: building a stability test platform of a landscape lighting control system, wherein the stability test platform integrates a client, a wireless network transmission end and a gateway node control end;
Step S200: data acquisition is carried out on the LED lighting programs of the target landscape area, so as to determine layout program files of the target landscape area;
Specifically, in order to solve the problems existing in the prior art: when the landscape lighting control system is used for controlling the landscape lighting, the system is difficult to perform complete stability detection, so that the problems of delay, paralysis and the like in the control of the landscape lighting are solved. The actual field application platform is built through software and hardware of the landscape lighting control system, and an actual test effect is given, so that complete stability detection of the landscape lighting control system is ensured, and stable transmission of data is ensured.
Specifically, the stability test platform is built based on the landscape lighting control system, wherein the landscape lighting control system is used for intelligently controlling the lighting of the target landscape area, and comprises lighting time control, light color switching and the like. The stability test platform integrates a client, a wireless network transmission end and a gateway node control end, wherein the client, the visual interpretation is an upper computer, can be understood as a client operation end supporting remote control management and program remote update, is used for issuing control instructions to the gateway node control end through the wireless network transmission end, and realizes remote control of a landscape area in a remote control mode, wherein the wireless network transmission end, the common TCP/IP transmission control protocol, realizes uninterrupted transmission of data, and the gateway node control end, the visual interpretation is a lower computer, is used for controlling a terminal of each lamp control node managed under jurisdiction, and further realizes instant control of each lamp control node on an LED illuminating lamp.
The target landscape area may be understood as a landscape lighting area of a park or a scenic spot, and the layout program file is a design of light change logic of the landscape lighting area, and may be specifically: the greening area of 100m 50m of a park is an actual scene, the greening area needs to be internally provided with LED lamps which slowly flash from 6 points at night, and then different lamplight effects including 7-color gradual change, sporadic flashing and three-color jumping lamp video effects are deduced every fifteen minutes.
Step S300: creating the layout program files based on file creation software to generate a created program file set;
Step S400: decomposing the set of the program files by using an upper computer program of the gateway node control end and the distribution of each lamp control node, so as to determine the program files of each lamp control node;
Specifically, after the lamplight change logic of a park is obtained, file production is needed, namely, the laid change logic is subjected to software design, so that the laid logic can be effectively operated, specifically, mr Player software can be utilized to produce corresponding program files according to the requirements of clients and the layout of LED lamps, specifically, mr Player software is LED lamp decoration system debugging software, the functions are powerful, simple and practical, user adaptation software can easily link an LED display screen, programs displayed by the LED display screen are rapidly managed and played, a plurality of play windows are supported to be edited and regulated on the same computer, and the method is very convenient. And the program file set is the animation file set which is formed by performing software on the well-laid light change logic. And the subsequent treatment is convenient.
After the overall light change animation file is produced, the light change animation file needs to be specific to the light change logic of each light control node. Therefore, the set of the program files can be decomposed by using the upper computer program of the gateway node control end and the distribution of each lamp control node, so as to determine the program files of each lamp control node. For example, a program making interface of the upper computer program may be opened, the made program file may be decomposed into corresponding terminal nodes, and the program file of each terminal node may be decomposed according to the condition that each terminal node controls the LED lamp. And opening a remote connection terminal interface of the upper computer, utilizing the remote connection lamp control gateway, then sending the program file of the node to the lamp control gateway through CAT.1, and then sending the program file to the appointed lamp control node through the WSN by the lamp control gateway, wherein the lamp control node can store the data after receiving the whole program data. The program files of each lamp control node are files received by a control node for directly controlling the LED lamp.
Step S500: setting a play program list and play time based on the client;
Step S600: and sending the play program list and the play time to the gateway node control end through the wireless network transmission end, triggering the lamp control gateway, playing the program files of each lamp control node in synchronous time, and testing the stability of the landscape lighting control system.
Further, step S600 includes:
Step S610: setting a DMX512 signal transmission protocol based on the gateway node control end;
Step S620: setting a TCP/IP network transmission protocol based on the wireless network transmission terminal;
step S630: and setting a double-layer protection frame loss retransmission mechanism between the TCP/IP network transmission protocol and the DMX512 signal transmission protocol to ensure the stability of the received data of the lamp control gateway.
As shown in fig. 2, step S630 includes:
step S631: obtaining sending frame data of the wireless network transmission end, wherein the sending frame data is embedded with a CRC check code field;
step S632: transmitting the transmission frame data to the gateway node control end, and performing CRC (cyclic redundancy check) on the transmission frame data to obtain a check result;
step S633: according to the verification result, if the verification is successful, the gateway node control end feeds back a confirmation frame to the wireless network transmission end;
Step S634: based on the confirmation frame, the wireless network transmission end sends the next frame data;
step S635: the gateway node control end performs data management on all received frame data and stores the frame data into a BIOS program, wherein the frame data is checked successfully;
step S636: after receiving all frame data through the BIOS program, uniformly checking the updated data frames of all frame data to obtain updated frame checking results;
Step S637: and according to the updated frame verification result, if frame loss data exists, the frame loss data is transmitted back to the wireless network transmission end for retransmission verification.
Specifically, after each light control node program file is determined, it may be subjected to stability detection of port transmission of data. Firstly, a play program list and play time can be set based on the client, wherein the play program list is the manufactured light change animation file, and the play time covers the starting time, the ending time, the time interval for switching each light change in the middle, the duration time of each light and the like of the light change in the landscape area. And then, the broadcasting program list and the broadcasting time are sent to the gateway node control end through the wireless network transmission end, a lamp control gateway is triggered, synchronous time broadcasting is carried out on the program files of all the lamp control nodes, and stability testing is carried out on the landscape lighting control system. In particular, since the data transmission protocols and the lamp control node transmission protocols common to the wireless network transmission end are different, the gateway is required to perform protocol conversion when data transmission is performed.
When the lamp control gateway is triggered to perform cross-network data transmission, a DMX512 signal transmission protocol is set at the gateway node control end to perform signal transmission, and a TCP/IP network transmission protocol is set at the wireless network transmission end, wherein the DMX512 is an internationally-used high-speed data output protocol, and an rs485 hardware circuit is adopted and is different from the general rs485 communication. Firstly, adopting unidirectional communication; secondly, the DMX512 communication needs to transmit low-level data of 88us as a start frame head of a packet of data, and a receiving party has a gap detection circuit and needs to find the start frame head of the data without communication verification; thirdly, the fixed baud rate of the DMX512 communication is 250kbps, and the communication protocol is open, so that the efficiency and the reliability are high, the DMX512 compatible communication interface is widely applied in the traditional stage industry, and the DMX512 compatible communication interface is the default choice in a high-power led lighting control system. The Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte stream based transport layer communication protocol. TCP is intended to accommodate a layered protocol hierarchy that supports multiple network applications. Reliable communication services are provided by means of TCP between pairs of processes in host computers connected to different but interconnected computer communication networks. TCP assumes that it can obtain simple, possibly unreliable datagram services from lower level protocols.
Furthermore, a double-layer protection frame loss retransmission mechanism can be set between the TCP/IP network transmission protocol and the DMX512 signal transmission protocol, so that the stability of the received data of the lamp control gateway is ensured. In order to ensure the stability of the received data of the lamp control gateway, a mechanism of frame loss retransmission is added to CAT.1 transmission. Especially, when the program is updated, if a bit of error occurs in the transmission process, the program may fail to update, so that a double-layer protection frame loss retransmission mechanism is adopted when the program is updated, and the stability of data transmission is ensured. As shown in fig. 3, a schematic diagram of a remote procedure update frame loss retransmission mechanism is shown.
The first layer of protection is that each frame of data has a response mechanism. The mechanism is updated based on serial port program, and has CRC check code field in the data of each frame, and the lower computer will perform CRC check after receiving the data and send back one confirmation frame to the upper computer program after successful check. The upper computer waits for the acknowledgement frame sent by the lower computer to send the next frame of data, and if the upper computer receives not acknowledgement information but retransmission information or does not receive a reply for a long time, retransmission is performed. The CRC is a cyclic redundancy check code, which is the most commonly used error checking check code in the field of data communication, and is characterized in that the lengths of an information field and a check field can be arbitrarily selected. Cyclic Redundancy Check (CRC) is a data transmission error detection function that performs polynomial computation on data and attaches the resulting result to the back of the frame, and the receiving device also performs a similar algorithm to ensure the correctness and integrity of the data transmission. The basic idea is to first append a number (this is the check code used for checking, but note that the number here is also a binary sequence, the same applies below) after the frame to be transmitted, and generate a new frame to be transmitted to the receiving end. Of course, this additional number is not arbitrary, and is intended to enable the new frame generated to be divided by a certain number selected jointly by the sender and the receiver (note that here, instead of directly using binary division, a so-called "modulo-2 division") is used. Upon arrival at the receiving end, the new received frame is divided (again using "modulo 2 division") by the selected divisor. Since the "discard" process (i.e., the integer division) is performed by appending a number before the sender sends the data frame, the result should be no remainder. If there is a remainder, this indicates that the frame has an error in the transmission.
The second layer of protection is that after all data frames are received, but before the BIOS program is updated, a check of all updated data frames needs to be performed once. If the frame is lost, the lost frame is sent to the upper computer to request retransmission, then the verification is carried out, and the BIOS can not update the program until the verification is successful. After all copying and inserting frame data, before the operation of updating command, the checking operation of the whole updating data frame is needed. Wherein BIOS is an abbreviation of English "Basic Input Output System", and the Chinese name is "basic input output System" after being translated. It should be referred to as ROM-BIOS, meaning read-only memory basic input output system. It is a set of programs solidified on a ROM chip on the main board in the computer, and it can save the most important basic input and output programs of computer, system setting information, power-on self-checking program and system start-up bootstrap program. Its main function is to provide the lowest, most direct hardware setup and control for the computer. The BIOS setting program is stored in the BIOS chip, and can be set only when the BIOS chip is started. The BIOS setting program is used to manage and set the basic input/output system of skill, so that the system operates in best state and the BIOS setting program may be used to eliminate system fault or diagnose system problem. By adopting a double-layer protection frame loss retransmission mechanism, the stability of data transmission is ensured, and therefore, the optimization of the communication stability of the lamp control gateway and the cloud is realized.
Further, the present application further includes step S700:
Step S710: constructing a network topology structure based on the distribution of the lamp control gateway and each lamp control node;
Step S720: and carrying out functional tests on the distribution of each lamp control node by utilizing the network topology structure and the upper computer program, wherein the functional tests comprise information display modification, play state setting, play time reservation and video play list reservation of the lamp control node.
As shown in fig. 4, step S720 includes:
Step S721: the playing time is subjected to feature classification to determine absolute time playing and relative time playing;
Step S722: acquiring the hardware local time among the lamp control nodes by utilizing the local hardware clock of the lamp control nodes and the time synchronization request initiated by the lamp control gateway;
Step S723: judging whether the hardware local time among the lamp control nodes is consistent with the set playing time;
Step S724: if the hardware local time among the lamp control nodes is consistent with the set playing time, the absolute time playing of the playing program list is realized;
step S725: setting a delay time interval by using the lamp control gateway;
step S726: setting playing time and the delay time interval through the receiving of the lamp control gateway, and calculating the relative playing time of the lamp control gateway;
Step S727: and sending the relative playing time to the lamp control node to realize the relative time playing of the playing program list.
Specifically, in addition to the above-mentioned test for the stability of data transmission of the system, the test needs to be performed on the client light control software. Because the system adopts the lamp control gateway to control the network topology structure of all the lamp control nodes, the management and control of the nodes are connected with the lamp control gateway through an upper computer program, and then the lamp control nodes are managed by forwarding data through the lamp control gateway. Because the microcontroller and the CAT.1 module communicate through the serial port, the essence of both connection modes is that the upper computer program is connected with the lamp control gateway through the serial port. Furthermore, the network topology and the upper computer program can be utilized to perform functional tests on the distribution of the light control nodes, wherein the functional tests comprise information display modification, play state setting, play time reservation and video play list reservation of the light control nodes.
Firstly, for the display and modification of node information, after the upper computer is connected with the lamp control gateway, the upper computer program can indirectly communicate with the appointed lamp control node through the lamp control gateway, and then the state (including the local time of node hardware, hardware address, software address and playing program) of the node can be read, and the state information is displayed. The node information can be modified by the upper computer and then sent to the appointed node. However, when the hardware and software addresses of the nodes are modified, the nodes can not be connected through the original lamp control gateway after the hardware addresses are modified, and if the original gateway is used, the hardware addresses of the lamp control gateway are also required to be changed into corresponding hardware addresses. The software address may not modify the repetition to prevent the scrambling of the data.
Secondly, for setting the playing state of the lamp control node and reserving playing, since the playing state of the lamp control node is the most basic function of the system, the states of all the lamp control nodes need to be set by one key to check whether the lamp control node works normally. A complete landscape lighting control system also needs to be capable of reserving the playing time of the lamp, and the playing time of the reserved lamp can be divided into absolute time and relative time. The absolute time is reserved through the local hardware clock of the node, and because the time synchronization request is initiated through the lamp control gateway, the hardware local time of each node is approximately the same, and when the hardware local time is the same as the set playing time, the playing is started at the same time, so that the effect of synchronous playing is achieved; the relative time is delayed by setting the time after the lamp control gateway receives the play time setting data, and then the lamp control gateway calculates the play time and sends the play time to all the lamp control nodes to realize synchronous play.
Thirdly, for updating the lamp control node video play list, the traditional landscape lighting control system adopts the SD card to store video play files, and the system adopts the internal Flash of the chip to store the video files, so that the SD card is not required to be pulled out and plugged in a computer to update when the traditional landscape lighting control system changes the video files, and only the lamp control gateway is connected through an upper computer program to send video play data to each node in a wireless mode, thereby reducing the later maintenance cost of the system. Comprehensive, the test of the client light control software is realized.
