Description

Technical Field

[0001] The present invention relates to the technical field of fire protection systems, and more specifically, to a method and system for quickly accessing a user information transmission device to a fire protection system platform. Background Art

[0002] The user information transmission device is the core front-end device of the urban fire remote monitoring center, which is used to obtain and transmit various user alarm information and equipment status information obtained from the user fire control host. Due to the large number of existing traditional fire protection system brands, various host models, and no unified host access methods and access protocols, the user information transmission device is the core link of the access capability of the traditional fire protection system in the urban fire remote monitoring center. Its compatibility, adaptability and maintainability are extremely important.

[0003] Figure 1 The basic architecture diagram of the user information transmission device is shown. The user information transmission device generally uses a wired method (such as CAN / Ethernet / RS232 / RS485 serial port) to connect and obtain data from the fire alarm host, and transmits this data to the city fire remote monitoring center through a wired network or a wireless network (such as 2G / 4G / 5G);

[0004] like Figure 2 As shown, the process of developing existing user information transmission devices to adapt to the protocols of various brands of fire alarm hosts is as follows:

[0005] 1. Construction workers usually use a computer to connect to the alarm host through the serial port on site, and manually trigger the alarm host to alarm. At this time, the original data of the alarm message is collected through the serial port.

[0006] This process has the following disadvantages:

[0007] a. Construction personnel need to master the method of collecting the original data of alarm messages through the serial port, and have certain requirements on the serial port software configuration and operation capabilities of construction personnel.

[0008] b. Due to the performance issues of the computer serial port tool, the collected data may be incomplete or disordered.

[0009] 2. The construction personnel will send the original data and alarm host protocol to the manufacturer of the user information transmission device on site, and the manufacturer's developers will develop and adapt it.

[0010] 3. Since the adaptation program takes several days to develop, the construction workers temporarily leave the construction site after installing the user information transmission device, connecting the equipment to the alarm host, and connecting to the city remote monitoring center through the network.

[0011] This process has the following disadvantages:

[0012] a. The manufacturer's developers cannot verify the integrity of the collected data in a timely manner and can only verify it after obtaining the collected data.

[0013] b. When the manufacturer's developers are developing the adapter program, if they find that the collected data is incomplete, the construction personnel will need to return to the site to collect data again. This will not only increase the construction and debugging costs, but also extend the development time.

[0014] 4. The manufacturer of the user information transmission device sends the adapter program to the construction personnel, who then go to the site to upgrade the program.

[0015] This process has the following disadvantages:

[0016] a. Construction personnel need to be trained on program upgrades, which not only increases communication costs, but also places certain requirements on the software operation capabilities of construction personnel.

[0017] b. There is a possibility of upgrade failure during the program upgrade process, which may cause the system to crash and make it impossible to start the system.

[0018] c. If the system cannot be started, the device needs to be returned to the factory for repair.

[0019] 5. The construction personnel conduct debugging on site and feedback the problems to the manufacturer of the user information transmission device.

[0020] This process has the following disadvantages:

[0021] a. Problem location and debugging are very troublesome. The manufacturer's developers cannot remotely connect to the device to locate the problem, and can only guide the construction personnel to do some simple problem location and log collection through remote guidance.

[0022] b. It takes a certain amount of time for the manufacturer to fix the program problem. After the manufacturer fixes the program problem, the new program still needs to be sent to the construction personnel. The construction personnel need to go to the site again to upgrade the program and do testing.

[0023] c. Since the manufacturer's developers cannot remotely connect to the device to locate the problem, they can only guess the problem based on communication with the construction personnel and make program repairs. Since there may be deviations in the communication between the two parties, it may be necessary to modify the program multiple times, and the construction personnel may have to go to the site to upgrade the program multiple times.

[0024] In order to solve the above problems, a new method and system for quickly accessing a user information transmission device to a fire protection system platform is needed. Summary of the invention

[0087] A method and system for quickly accessing a fire protection system platform through a user information transmission device in a preferred embodiment of the present invention, such as Figure 3 See also Figure 4-Figure 6 , the method comprises the steps of:

[0088] S01: Before installing the user information transmission device on site, send the alarm host protocol to the manufacturer of the user information transmission device;

[0089] S02: After the user information transmission device is installed on site, the device is connected to the external network. According to the settings, the user information transmission device establishes a network communication connection with the manufacturer's platform by default to perform data encryption transmission;

[0090] S01 and S02 specifically include:

[0091] Before going to the site, the construction personnel will send the alarm host protocol to the manufacturer of the user information transmission device in advance, so that the manufacturer's developers can be familiar with the alarm host protocol in advance.

[0092] The construction personnel install the user information transmission device on site, connect the device to the alarm host, and access the external network. At this time, the user information transmission device will be connected to the manufacturer's equipment management platform by default.

[0093] The user information transmission device and the manufacturer's equipment management platform support multiple communication methods such as wired network, 2G / 4G / 5G wireless network, etc.

[0094] The user information transmission device provides HTTPS POST+JSON or MQTT+SSL+JSON to establish a communication connection with the manufacturer's equipment management platform, and performs encrypted data transmission to ensure data integrity and secure transmission.

[0095] The data transmitted between the user information transmission device and the manufacturer's equipment management platform includes the user information transmission device equipment information and status, alarm host alarm data, fire protection facility data, reverse connection instructions, control instructions, upgrade programs, etc.;

[0096] S03: Actively trigger the alarm host to alarm, and automatically send the collected original data of the alarm host to the manufacturer's equipment management platform according to the set user information transmission device, so that the integrity of the data can be obtained and verified in real time on the manufacturer's equipment management platform;

[0097] Specifically include:

[0098] The user information transmission device provides AK (Access Key ID), SK (Secret Access Key) and encryption algorithm to the manufacturer's equipment management platform.

[0099] The manufacturer management platform uses the AK / SK authentication mechanism in its authorization verification process. When the user information transmission device reports data, it will bring AK and signature (the signature obtained by encrypting the content using SK) for request.

[0100] The manufacturer management platform decrypts the request according to the algorithm and verifies the content of the request. Only requests that pass the verification will be executed.

[0101] When construction workers manually trigger the alarm host to alarm on site, the user information transmission device will automatically send the collected original data of the alarm host to the manufacturer's equipment management platform through an encrypted channel.

[0102] The manufacturer's equipment management platform stores the original data of the alarm host collected by the user's information transmission device locally for the manufacturer's developers to obtain.

[0103] Manufacturer developers can obtain and verify the integrity of data in real time on the manufacturer's equipment management platform;

[0104] S04: After developing the script according to the alarm host protocol and the original data of the alarm host, the adaptation script is published to the manufacturer's equipment management platform;

[0105] S05: After the upload is completed, the management platform detection program automatically verifies the script syntax of the adaptation script. When the script passes the verification, it is officially released and the MD5 value and version number of the file are automatically generated;

[0106] S06: The user information transmission device communicates with the manufacturer's equipment management platform to obtain the latest version number of the specified adaptation script, and compares it with the current version number of the local script. If it is detected that the version number of the adaptation script of the management platform has been updated, it automatically requests the management platform to download the adaptation script, otherwise no action is taken;

[0107] S04, S05 and S06 specifically include:

[0108] The manufacturer's developers will publish the adaptation script to the manufacturer's equipment management platform. After the upload is completed, the management platform detection program will automatically perform a syntax check on the script. Only scripts that pass the check will be officially released, and the MD5 value and version number of the file will be automatically generated.

[0109] The user information transmission device communicates with the manufacturer's equipment management platform, regularly obtains the latest version number of the specified adaptation script, and compares it with the current version number of the local script. If it detects that the version number of the management platform's adaptation script has been updated, it automatically requests the management platform to download the adaptation script. The management platform's adaptation script supports downloading via HTTP, FTP, etc.

[0110] After the user information transmission device downloads the latest version of the adaptation script to the local computer, before the script takes effect, the detection program automatically performs a syntax check on the script, and after the syntax check passes, an integrity check is also performed. The new version of the adaptation script will only be loaded and take effect by the main program after passing the syntax check and integrity check;

[0111] Compared with the existing technical solutions, the present invention only needs to install the user information transmission device, and the device will be connected to the manufacturer's platform by default as long as it is connected to the external network. The construction personnel only need to manually trigger the alarm host alarm on site, and the device will automatically send the collected alarm host original data to the manufacturer's platform; the alarm host original data collected by the present invention will be transmitted to the manufacturer's platform in real time, and the manufacturer's developers can obtain and verify the integrity of the data in the manufacturer's platform in real time;

[0112] It has at least the following advantages:

[0113] 1. The original data collection of the alarm host is relatively convenient, the cost of docking and adapting the alarm host protocol is low, and the requirements for construction personnel are relatively low;

[0114] 2.Equipment program debugging and upgrading are simple;

[0115] 3. The program framework ensures system security and data security, and prevents system crashes caused by abnormal adaptation scripts.

[0116] The method also includes:

[0117] S07: remotely debug the user information transmission device;

[0118] Specifically include:

[0119] The user information transmission device is generally installed in the on-site LAN environment, and the manufacturer's developers cannot directly access the device remotely in the external network. Therefore, the present invention adopts SSH reverse tunnel technology to realize remote access to the device.

[0120] The developer sends a reverse SSH connection instruction to the user information transmission device through the device management platform. The instruction contains information such as the remote SSH server address, port, user name, and password.

[0121] After receiving the reverse SSH connection instruction, the user information transmission device initiates an SSH connection to the remote SSH device and establishes a reverse SSH tunnel.

[0122] Developers can remotely access the user information transmission device through the reverse SSH tunnel on the remote SSH server to remotely locate and fix problems.

[0123] The specific implementation is described as follows:

[0124] like Figure 4As shown in the figure, the specific steps of the alarm host raw data collection process are as follows:

[0125] 1. After the user information transmission device is installed and connected to the external network, it will send a connection request to the manufacturer's equipment management platform by default.

[0126] 2. After receiving the device connection request, the manufacturer's device management platform verifies the request and establishes a network communication connection after the verification passes.

[0127] 3. The manufacturer's equipment management platform returns a connection success response to the user's information transmission device, and the two parties can subsequently perform encrypted data transmission through the connection.

[0132] 8. The manufacturer's equipment management platform stores the original data of the alarm host collected by the user information transmission device locally for the manufacturer's developers to obtain.

[0133] like Figure 5 As shown, the specific steps of the remote upgrade process of the user information transmission device are as follows:

[0134] 1. The manufacturer's developers publish the adaptation script to the manufacturer's device management platform.

[0135] 2. After the adaptation script is uploaded, the management platform detection program automatically verifies the script syntax. Only scripts that pass the verification will be officially released.

[0136] 3. The management platform passes the verification and returns a successful response to the script release.

[0137] 4. The user information transmission device communicates with the manufacturer's equipment management platform and regularly requests the latest version information of the specified adaptation script.

[0138] 5. The management platform returns the latest version information of the specified adaptation script, which includes the version number, file MD5 value, etc.

[0139] 6. The user information transmission device compares the latest version number of the adaptation script with the current version number of the local script. If the latest version number is greater than the current version number, it is considered that the adaptation script has been updated.

[0140] 7. If the user information transmission device detects that the version number of the management platform adaptation script has been updated, it will automatically request the management platform to download the adaptation script, and supports downloading via HTTP, FTP, etc.

[0141] 8. The management platform returns the latest version of the script file.

[0142] 9. After the user information transmission device downloads the latest version of the adaptation script to the local computer, the detection program automatically performs a syntax check on the script before the script takes effect. After the syntax check passes, an integrity check is also performed. The new version of the adaptation script will only be loaded and take effect by the main program after passing the syntax check and integrity check.

[0143] like Figure 6 As shown, the specific steps of the remote debugging process of the user information transmission device are as follows:

[0144] 1. The developer operates the device management platform interface and requests remote debugging operations.

[0145] 2. The device management platform sends a reverse SSH connection instruction to the user information transmission device, which contains information such as the remote SSH server address, port, user name, password, etc.

[0146] 3. After receiving the reverse SSH connection instruction, the user information transmission device verifies the instruction.

[0147] 4. After the user information transmission device verifies the instruction, it initiates a reverse SSH connection request to the remote SSH server.

[0148] 5. The remote SSH server receives the reverse SSH connection request and establishes a reverse SSH tunnel connection.

[0149] 6. The remote SSH server sends a reverse SSH connection success response to the user information transmission device.

[0150] 7. The user information transmission device sends a successful command execution response to the device management platform.

[0151] 8. The device management platform pops up a prompt "Remote debugging preparation is complete" in the interface.

[0152] 9. The developer operates the device management platform interface to open the remote debugging interface.

[0153] 10. The device management platform sends an SSH connection request to the remote SSH server.

[0154] 11. The remote SSH server forwards the SSH connection request of the device management platform to the user information transmission device through the reverse SSH tunnel.

[0155] 12. The user information transmission device receives the SSH connection request and returns a successful response to the connection request to the remote SSH server through the reverse SSH tunnel.

[0156] 13. The remote SSH server sends a successful SSH connection response to the device management platform.

[0157] 14. The remote debugging interface of the device management platform prompts the developer that "remote debugging is started successfully". Subsequent developers enter standard SSH commands in the remote debugging interface, which will be forwarded to the user information transmission device through the reverse SSH tunnel previously established on the remote SSH server. The user information transmission device receives the SSH command and returns the result of executing the command to the device management platform through the tunnel and displays it in the remote debugging interface.

[0181] The program framework of the user information transmission device in the present invention includes two parts: one is the main application program, which is developed in C language. No matter what brand of alarm host is connected, the same set of main application programs are run; the other is the alarm host protocol adapter program, which is a script program written in Lua and runs in a specially constructed safe Sandbox environment. Each alarm host brand corresponds to an adapter script. This has the following advantages:

[0182] 1. The adapter is developed in the Lua scripting language and can be run directly without compilation, making it convenient for developers to quickly debug and modify.

[0183] 2. Sandbox is a security mechanism that allows programs to run in a relatively independent and isolated environment so that they do not affect external programs and ensure system security. When the adapter runs in a sandbox environment, even if the adapter has serious defects, it will not affect the external main program and operating system, and will not cause the system to crash.

[0184] 3. The adapter program supports remote upgrades. When upgrading, you only need to update the adapter program without upgrading the entire main program. At the same time, the program upgrade does not need to be restarted to take effect. This not only avoids the problem of construction personnel needing to upgrade the program on site, but also avoids the problem of upgrading the main program version incorrectly.

[0185] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
