Description

Technical Field

[0001] This invention belongs to the field of computer system operation and maintenance technology, and specifically relates to an operation and maintenance method and system for an electrical fire monitoring center. Background Technology

[0002] Electrical fires are disasters caused by combustion resulting from electrical causes. Short circuits, overloads, and electrical leaks can all lead to fires. Direct causes of electrical fires include equipment defects, improper construction and installation, poor electrical contact, and high temperatures, arcs, and sparks caused by lightning strikes and static electricity. The characteristics of electrical fires are the distributed, continuous, and concealed nature of their fire hazards. Because electrical systems are widely distributed and operate continuously for extended periods, electrical wiring is usually laid in concealed locations (such as ceilings and cable trenches), making it difficult for fire alarm systems to detect in the early stages of a fire, and also difficult to observe with the naked eye. The danger of electrical fires is also closely related to electricity usage; when the electrical load increases, overcurrent can easily cause electrical fires. Currently, the most commonly used fire alarm control solutions are distributed automatic fire alarm systems or wireless automatic alarm systems. Both require fire alarm devices to be installed in electrical distribution cabinets. Although they can alarm and extinguish fires based on collected data, current system maintenance is cumbersome, system upgrade costs are too high, and the system's compatibility and scalability need further improvement. Summary of the Invention

[0003] This invention provides examples of various operation and maintenance methods for electrical fire monitoring centers. Generally, the server communicates with several back-end / control room terminals and a management terminal via TCP / IP protocol; the back-end / control room terminals communicate with the fire suppression control unit via RS485 protocol; the fire suppression control unit communicates with the server via GSM protocol and also with the fire suppression controller via a short-range wireless communication protocol; at least one fire suppression controller communicates with the fire suppression control unit via RS485 protocol; each fire suppression controller is electrically connected to a fire suppression device and is located in a fire-fighting position; each back-end / control room terminal and its managed subordinate machines are located in a fire-fighting zone.

[0004] The steps for updating the software and hardware versions of the fire suppression host on the backend / control room side include:

[0005] i. Obtain the current software version installation package name and the current hardware version installation package name from the upgrade directory of the storage space of the fire extinguishing host; download the upgradeable software version installation package and the upgradeable hardware version installation package from the server;

Modify the name of the upgradeable software version installation package that contains the name of the current software version installation package to the name of the updated software version installation package, and send it to the upgrade directory of the storage space of the fire extinguishing host and delete the current software version installation package. Then the fire extinguishing host completes the software version upgrade. Otherwise, if the name of the current software version installation package is not included, proceed to iv.

[0008] iv. Among all the names of the most recent upgradable hardware versions corresponding to the name of the software version installation package that does not contain the name of the current hardware version installation package, modify the names of the upgradable hardware version installation packages that contain the name of the current hardware version installation package to update the hardware version installation package name, delete the current hardware version installation package, and then send it to the upgrade directory of the fire extinguishing host's storage space. The fire extinguishing host then completes the hardware version upgrade. Otherwise, if the name of the current hardware version installation package is not included, return i.

[0009] The steps for updating the hardware version of the fire suppression controller at the back-end / control room end include:

[0010] i. Obtain the name of the current hardware version installation package in the upgrade directory of the storage space of the fire extinguishing controller; download the name of the upgradeable software version installation package and the name of the upgradeable hardware version installation package from the server;

[0011] ii. Match the current hardware version installation package name with the name of the upgradeable hardware version installation package downloaded from the server;

[0012] iii. Modify the name of the upgradeable hardware version installation package that contains the name of the current hardware version installation package to the name of the updated hardware version installation package, and send it to the upgrade directory of the fire extinguishing controller's storage space and delete the current hardware version installation package. Then the fire extinguishing controller completes the software version upgrade. Otherwise, if the name of the current hardware version installation package is not included, return to i.

[0013] This invention provides an operation and maintenance system for various electrical fire monitoring centers. The system includes at least one processor and a memory storing instructions that, when executed by the at least one processor, implement the method described in the foregoing method examples.

[0022] Please continue to refer to this. Figure 1 In some embodiments, the steps for updating the software and hardware versions of the fire suppression system on the back-end / control room side include:

[0023] i. Obtain the current software version installation package name and the current hardware version installation package name from the upgrade directory of the storage space of the fire extinguishing host; download the upgradeable software version installation package and the upgradeable hardware version installation package from the server;

[0024] ii. Match the name of the current software version installation package with the name of the upgradeable software version installation package downloaded from the server;

[0025] iii. Modify the name of the upgradeable software version installation package that contains the name of the current software version installation package to the name of the updated software version installation package, and send it to the upgrade directory of the fire extinguishing host's storage space and delete the current software version installation package. Then the fire extinguishing host completes the software version upgrade. Otherwise, if the name of the current software version installation package is not included, proceed to iv.

[0026] iv. Among all the names of the most recent upgradable hardware versions corresponding to the name of the software version installation package that does not contain the name of the current hardware version installation package, modify the names of the upgradable hardware version installation packages that contain the name of the current hardware version installation package to update the hardware version installation package name, delete the current hardware version installation package, and then send it to the upgrade directory of the fire extinguishing host's storage space. The fire extinguishing host then completes the hardware version upgrade. Otherwise, if the name of the current hardware version installation package is not included, return i.

The upgradeable software version installation package downloaded from the server is v1.0.2.0, and the upgradeable hardware version installation package is G2.1.2.2. After the software version matches, the current software version v1.0 is changed to v2.0. After the hardware version matches, the current hardware version G2.1 is changed to G2.2.

[0028] Please continue to refer to this. Figure 1 In some embodiments, the steps for updating the hardware version of the fire suppression controller at the back-end / control room end include:

[0029] i. Obtain the name of the current hardware version installation package in the upgrade directory of the storage space of the fire extinguishing controller; download the name of the upgradeable software version installation package and the name of the upgradeable hardware version installation package from the server;

[0030] ii. Match the current hardware version installation package name with the name of the upgradeable hardware version installation package downloaded from the server;

[0031] iii. Modify the name of the upgradeable hardware version installation package that contains the name of the current hardware version installation package to the name of the updated hardware version installation package, and send it to the upgrade directory of the fire extinguishing controller's storage space and delete the current hardware version installation package. Then the fire extinguishing controller completes the software version upgrade. Otherwise, if the name of the current hardware version installation package is not included, return to i.

[0032] In some embodiments, the backend / control room terminal updates the software and hardware versions of the fire extinguishing host based on the host ID of the fire extinguishing host, and the backend / control room terminal updates the hardware version of the fire extinguishing controller based on the host ID of the fire extinguishing host or the fire extinguishing controller ID. Compared to some scenarios that require manual programming of the fire extinguishing host or fire extinguishing controller based on RS232 protocols, the anti-collision requirements for host ID and controller ID are not high. However, for scenarios that require a more intelligent architecture to integrate fire extinguishing controllers developed based on microcontrollers and those based on intelligent systems, the anti-collision requirements for host ID and controller ID are a problem that must be solved.

[0033] In some embodiments, the step of obtaining the host ID of the fire suppression host at the back-end / control room includes:

[0034] i. Obtain the host serial number of the fire extinguishing host and generate the host ID. If the host serial number fails the verification, proceed to ii.

[0035] ii. Obtain the port of the host ID in the software installation program of the fire extinguishing host and the port list maintained by the host computer, and obtain the host ID from the port;

[0036] The steps for obtaining the controller ID of the fire suppression controller at the back-end / control room end include:

[0037] i. Obtain the port of the controller ID of the fire extinguishing controller or the port list maintained by its host computer, obtain the controller ID from the port, and if the verification fails, proceed to ii.

[0038] ii. Obtain the alarm history data of the fire extinguishing controller and calculate the hash value to obtain the device ID. The alarm history includes at least one alarm history containing fire location data, temperature data, smoke detector data, fire extinguisher data, and serial number data. For example, an alarm history might be: "Location: Power Distribution Center 1 Temperature: 028 Smoke Detector: Abnormal Fire Extinguisher: Activated Serial Number: 10". In a preferred embodiment, the alarm history data is sent from the fire extinguishing host to the backend / control room via the GSM protocol. The backend / control room verifies the alarm history data obtained using different transmission methods, which can increase the data's anti-tampering performance.

[0039] In a further preferred embodiment, calculating the hash value further includes one or more of the following: timestamp, port number, channel number, and the current hardware version name of the fire suppression controller.

[0040] The hash value of the alarm history data at time i is calculated, where i is a direct proportional function of the number of fire extinguishing controllers. The duration of "time i" is not limited in this invention; for example, 24 hours, with one historical record per minute, would result in 1440 historical data records, which is sufficient for fewer than 100 fire extinguishing controllers. If the number of fire extinguishing controllers increases to 300, 72 hours can be selected. In a preferred embodiment, the direct proportional function can be preset in the program, and the system will automatically adjust time i according to the number of fire extinguishing controllers.

[0041] In some embodiments, the controller ID of the fire extinguishing controller is generated by the fire extinguishing host based on the entered information; when the backend / control room saves the controller ID, it also adds the host ID. For fire extinguishing controllers that have just joined the network or have no alarm history, a temporary controller ID can be generated in this way to meet the requirements of device initialization. Once the conditions of the aforementioned "step of obtaining the controller ID of the fire extinguishing controller on the backend / control room side" are met, a formal controller ID is generated.

[0042] In some embodiments, the fire suppression host has multiple preset channels. When any channel detects a fire suppression controller, the fire suppression host assigns a temporary controller ID to that controller. When the backend / control room obtains the temporary controller ID, if it detects that a fire suppression host or controller on the same channel is invalid, it refuses to generate a device ID according to the conditions of the aforementioned "step of obtaining the controller ID of the fire suppression controller by the backend / control room". The method for verifying the invalidity of the fire suppression host or controller is not limited in this invention. For example, a password table for the fire suppression host, the upper limit of fire suppression controllers managed by a fire suppression host, and the hardware models of the fire suppression host and controller can be maintained on the server side.

[0043] In some embodiments, the method for channel allocation at the back-end / control room end is as follows: the ports A1 / B1 of the fire extinguishing host traverse the ports A / B of the fire extinguishing controller via the RS485 protocol; the channel and controller ID of the fire extinguishing controller are modified. This method can achieve temporary modification of the channel and controller ID.

[0044] In some embodiments, the architectural logic reference of the electrical fire monitoring center Figure 2 As shown: with Figure 1In addition, it also includes a fire protection zone formed by the server 100 communicating with several intelligent controllers 401 via TCP / IP protocol 3. The intelligent controllers 401 can be installed in an intelligent operating system to control the placement of fire extinguishing equipment in fire-fighting positions (not shown in the figure). In this way, the server 100 can manage different types of fire extinguishing controllers at the same time, which is very convenient for equipment upgrades and iterations.

[0045] In some embodiments, the controller ID of the smart controller 401 can be based on IMEI, MAC, Google identifier, operating system version, Android identifier, APP application, application process data (process data of other APPs in the operating system where the fire extinguishing APP is located), and hard disk serial number to enhance the anti-collision performance and security performance of the controller ID.

[0046] The operation and maintenance method of the electrical fire monitoring center of the present invention can be applied to different automatic alarm and fire extinguishing information platforms, such as... Figure 3 The diagram illustrates a typical application topology of this invention, where a remote alarm server and a backend alarm server are used in a given scenario. The remote alarm server and the backend alarm server receive data from the alarm and fire suppression system host, the alarm and fire controller, and the automatic fire extinguishing device, and provide services to these lower-level devices. The alarm and fire suppression system host includes a communication module, an alarm display module, and an audible and visual alarm module. The alarm and fire controller monitors the environment through smoke detection and temperature detection modules, triggers an alarm through the audible and visual alarm module, performs logical judgments through a logic judgment module, and then controls the automatic fire extinguishing device through the fire extinguishing control module. (Reference) Figure 4The diagram shows the GUI interface of the remote alarm server and the backend alarm server, featuring modules for port settings, location settings, telephone settings, warning logs, and alarm clearing. In this system, the data communicating with several automatic fire suppression system hosts is real-time monitoring data, including temperature data, smoke detection data, and fire extinguisher status data. Each automatic fire suppression system host is assigned a port, and a port option (com4) button is generated in the power distribution center GUI interface. Several power distribution centers are constructed for each automatic fire suppression system host, and at least location data, telephone data, warning log data, and alarm clearing data are mapped to the data of any constructed power distribution center. Address setting buttons, telephone setting buttons, warning setting buttons, and alarm clearing data buttons are generated in the power distribution center GUI interface. The telephone data is collected from several automatic fire suppression system hosts or several real-time monitoring PCs, and the location data is the location matched based on the power distribution center name. Each line of alarm history includes: controller location data, temperature data, smoke detection data, fire extinguisher status data, and controller number data. This system uses distributed remote sensing modules to quickly monitor changes in the surrounding environment. Once a fire is detected, the system will quickly send an alarm signal via wireless communication, indicating the location and time of the fire. While supporting remote communication and fire alarm, it can also automatically extinguish fires, ensuring that the fire is extinguished as soon as possible.
