Example one
As shown in fig. 1, the present application provides a stability testing method for a landscape lighting control system, the method being applied to a stability testing system, the method comprising:
step S100: the method comprises the steps of building a stability test platform of the landscape lighting control system, wherein the stability test platform integrates a client, a wireless network transmission terminal and a gateway node control terminal;
step S200: acquiring data of LED lighting programs of a target landscape area to determine a layout program file of the target landscape area;
specifically, to address the problems existing in the prior art: when utilizing landscape lighting control system to control landscape lighting, be difficult to carry out complete stability to this system and detect, lead to appearing delaying, paralyzing etc. trouble to the control of landscape lighting to solve, the stability test method of landscape lighting control system that this application provided. An actual field application platform is built through software and hardware of the landscape lighting control system, an actual test effect is given, complete stability detection of the landscape lighting control system is guaranteed, and stable data transmission is guaranteed.
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 lighting of the target landscape area, including lighting time control, lighting 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 is used for issuing a control instruction to the gateway node control end in a remote control mode to realize remote control of a scene area by taking an upper computer as an visualized explanation and a client operation end capable of realizing remote control management and remote program updating as an understandable, and the wireless network transmission end is used for realizing uninterrupted data transmission based on a common TCP/IP transmission control protocol and is used for carrying out terminal control on each lamp control node managed under jurisdiction so as to further realize the 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 certain park or a scenic spot, and the layout program file is designed for a light change logic of the landscape lighting area, and may specifically be, for example: the greening area of 100m by 50m of a certain park is an actual scene, the LED lamps on the trees slowly flicker from 6 o' clock at night in the greening area, and then different lighting effects including 7-color gradual change, sporadic flicker and three-color hopping lamp video effects are performed every fifteen minutes.
Step S300: making the layout program file based on file making software to generate a making program file set;
step S400: decomposing the production program file set by utilizing an upper computer program of the gateway node control end and the distribution of each lamp control node so as to determine each lamp control node program file;
particularly, after obtaining the light change logic of a certain park, file making is needed to be carried out on the light change logic, namely software design is carried out on the well-arranged change logic, so that the well-arranged logic can be effectively operated, specifically, Mr Player software can be utilized, corresponding program files are made according to customer requirements and the arrangement of LED lamps, specifically, the Mr Player software is LED lamp decoration system debugging software, the functions are powerful, simple and practical, a user can easily link an LED display screen by adapting to the software, the displayed programs are rapidly managed and played, and a plurality of playing windows are supported to be edited and regulated on the same computer, so that the park light change logic is very convenient. And the program file set is an animation file set for carrying out software on the well-laid lamplight change logic. Facilitating the subsequent treatment thereof.
After the overall lighting change animation file is manufactured, the lighting change animation file needs to be embodied to the lighting change logic of each light control node. Therefore, the production program file set can be decomposed by utilizing the upper computer program of the gateway node control end and the distribution of each lamp control node, so as to determine each lamp control node program file. Illustratively, a program making interface of the upper computer program can be opened, the made program file is decomposed into corresponding terminal nodes, and the program file of each terminal node is 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, sending the program file of the node to the lamp control gateway through CAT.1, sending the program file to the specified lamp control node through the WSN by the lamp control gateway, and storing the data after receiving the full program data by the lamp control node. And the program files of the lamp control nodes are files received by the control nodes for directly controlling the LED lamps.
Step S500: setting a playing program list and playing time based on the client;
step S600: and sending the playing program list and the playing time to the gateway node control end through the wireless network transmission end, triggering the lamp control gateway, carrying out synchronous time playing on the program files of the lamp control nodes, and carrying out stability test on 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: acquiring sending frame data of the wireless network transmission end, wherein a CRC check code field is embedded in the sending frame data;
step S632: sending the sending frame data to the gateway node control end, and simultaneously carrying out CRC (cyclic redundancy check) on the sending frame data to obtain a check result;
step S633: according to the check result, if the check 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 terminal 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 to a BIOS program, wherein the frame data are verified successfully;
step 636: after receiving all the frame data through the BIOS program, uniformly verifying the update data frame of all the frame data to obtain an update frame verification result;
step S637: and according to the updated frame check result, if frame loss data exists, returning the frame loss data to the wireless network transmission end for retransmission check.
Specifically, after determining each lamp control node program file, stability detection of port transmission of data may be performed thereon. Firstly, a playing program list and playing time can be set based on the client, wherein the playing program list is the manufactured lighting change animation file, and the playing time covers the starting time and the ending time of the lighting change of the landscape area, the time interval of the middle switching of the lighting change, the duration of each lighting, and the like. And then, the playing program list and the playing time are sent to the gateway node control end through the wireless network transmission end, the lamp control gateway is triggered, the synchronous time playing is carried out on the program files of the lamp control nodes, and the stability test is carried out on the landscape lighting control system. Specifically, because a data transmission protocol common to the wireless network transmission end is different from a lamp control node transmission protocol, a gateway is required to perform protocol conversion during data transmission.
When the lamp control gateway is triggered to perform cross-network data transmission, the gateway node control end is provided with a DMX512 signal transmission protocol for signal transmission, and the wireless network transmission end is provided with a TCP/IP network transmission protocol, wherein the DMX512 is an international universal protocol for high-speed data output, and an rs485 hardware circuit is adopted, which is different from general rs485 communication. Firstly, one-way communication is adopted; secondly, the DMX512 communication needs to transmit 88us of low-level data as a starting frame header of a packet of data, a gap detection circuit at a receiving party needs to find the starting frame header of the data, and no communication check exists; thirdly, the fixed baud rate of DMX512 communication is 250kbps, and because the communication protocol is open, the efficiency and the reliability are high, the DMX512 communication interface is widely applied in the traditional stage industry, and is a 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 layered protocol hierarchies that support 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 service 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 data received by the light control gateway, a frame loss retransmission mechanism is added to CAT.1 transmission. Especially, when the program is updated, if a bit of error occurs in the transmission process, the program update may fail, so a frame loss retransmission mechanism with double-layer protection is adopted during the program update, and the stability of data transmission is ensured. Fig. 3 is a schematic diagram of a frame loss retransmission mechanism for remote procedure update.
The first layer of protection is that each frame of data has a response mechanism. The mechanism is updated based on a serial port program, a CRC (cyclic redundancy check) code field is arranged in data of each frame, a lower computer carries out CRC after receiving the data, and a confirmation frame is sent back to an upper computer program after the CRC is successful. The upper computer waits for the confirmation frame sent by the lower computer to send next frame data, and if the upper computer receives the retransmission information instead of the confirmation information or does not receive the reply for a long time, the upper computer retransmits the data. CRC, i.e. cyclic redundancy check code, is a kind of error checking code most commonly used in the field of data communication, and is characterized in that the lengths of the information field and the check field can be arbitrarily selected. Cyclic Redundancy Check (CRC) is a data transmission error detection function that performs polynomial calculations on data and appends the resulting result to the frame, and the receiving device also performs similar algorithms to ensure the correctness and integrity of the data transmission. The basic idea is to add a number (this is the check code used for checking, but it should be noted 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 it is intended to divide the new frame generated by an integer number of a particular number selected in common by the transmitting end and the receiving end (note that here, instead of using binary division directly, a so-called "modulo-2 division" is used). Upon arrival at the receiving end, the received new frame is divided (again by "modulo-2 division") by the selected divisor. Since the "remainder" process is done by appending a number (i.e., it is already divisible) before the data frame is transmitted by the transmitting end, the result should be no remainder. If the remainder is available, the frame is indicated to have errors in the transmission process.
The second layer protection is to check all the updated data frames once after all the data frames are received but before the program update of the BIOS program. If the lost frame occurs, the lost frame is sent to the upper computer to require retransmission, then verification is carried out, and the BIOS can not update the program until the verification is successful. After all the copied and inserted frame data are finished, before the operation of updating command, the verification operation of updating data frame integrally is needed. The BIOS is an abbreviation of the English Basic Input Output System, and the Chinese name after translation is the Basic Input Output System. It shall be referred to as ROM-BIOS, meaning ROM BIOS. In fact, it is a set of programs solidified on a ROM chip on the main board of the computer, and it stores the most important basic input and output programs of the computer, system setting information, power-on self-test program and system boot bootstrap program. Its primary function is to provide the lowest level, most direct hardware setup and control for the computer. The BIOS setup program is stored in the BIOS chip and can be set only when the computer is powered on. The BIOS setting program mainly manages and sets the skill basic input and output system, so that the system runs in the best state, and system faults can be eliminated or system problems can be diagnosed by using the BIOS setting program. By adopting a double-layer protection frame loss retransmission mechanism, the stability of data transmission is ensured, and thus the communication stability optimization 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 lamp control gateway and the distribution of each lamp control node;
step S720: and performing functional test on the distribution of each lamp control node by using the network topological structure and the upper computer program, wherein the functional test comprises information display modification, playing state setting, playing time reservation and video play list reservation of the lamp control nodes.
As shown in fig. 4, step S720 includes:
step S721: the playing time is subjected to characteristic classification to determine absolute time playing and relative time playing;
step S722: acquiring hardware local time between the lamp control nodes by using a local hardware clock of the lamp control nodes and a time synchronization request initiated by the lamp control gateway;
step S723: judging whether the hardware local time between the lamp control nodes is consistent with the set playing time or not;
step S724: if the hardware local time between 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 utilizing the lamp control gateway;
step S726: setting the 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 playing of the relative time of the playing program list.
Specifically, in addition to the above-mentioned test of the data transmission stability of the system, the test of the client light control software is also required. 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 must be 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 microcontroller and CAT.1 module communicate through the serial ports, so the essence of two kinds of connected modes is in fact that the host computer program passes through serial ports and connects lamp accuse gateway. And further, the network topology structure and the upper computer program can be utilized to perform functional test on the distribution of each lamp control node, wherein the functional test comprises information display modification, playing state setting, playing time reservation and video play list reservation of the lamp control nodes.
For the first, for the display and modification of the 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 of the node (including the local time of the node hardware, the hardware address, the software address and the program being played) can be read, and the state information is displayed. And node information can be modified through the upper computer and then sent to the designated node. However, when the hardware and software addresses of the nodes are modified, the nodes cannot be connected through the original light control gateway after the hardware addresses are modified, and if the original gateway is used, the hardware address of the light control gateway is also changed into the corresponding address. The software address may not be modified to be repeated to prevent confusion of data.
Secondly, for setting the playing state of the lamp control nodes and the reserved playing, since the setting of the playing state of the lamp control nodes 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 nodes work normally or not. A complete landscape lighting control system also needs to be able to achieve the playing time of the reservation lamp, and the playing time of the reservation lamp can be divided into absolute time and relative time. The absolute time is reserved through a local hardware clock of the node, and as a 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 of the lamp control gateway after receiving the playing time setting data, and then the lamp control gateway calculates the playing time and sends the playing time to all the lamp control nodes to realize synchronous playing.
Thirdly, for updating the lamp control node video playing list, the traditional landscape lighting control system adopts the SD card to store the video playing file, the system adopts the internal Flash of the chip to store the video file, so that the traditional landscape lighting control system does not need to pull out and insert the SD card off line and then insert a computer to update when the video file is replaced, and only needs to connect the lamp control gateway through an upper computer program to send the video playing data to each node in a wireless mode, thereby reducing the later maintenance cost of the system. And comprehensively, the test of the client light control software is realized.
