Description

TECHNICAL FIELD

[0001] The utility model relates to electrical fire monitoring technical field especially relates to a kind of electrical fire monitoring management system. BACKGROUND

[0002] With the development of science and technology, electrical fire monitoring and early warning are paid more and more attention, and the traditional electrical fire monitoring system has obvious limitations in functional architecture, and the core problem is reflected in the split design of management function and monitoring capability. The traditional monitoring host is usually only used as a data collection and display terminal, and all real-time monitoring of fire hazards, parameter collection and primary analysis functions completely depend on various detector devices installed in the front end.

[0003] This functional separation architecture exposes multi-dimensional defects in actual application: first, the system functionality is split by physical devices, resulting in monitoring sensitivity and response speed being subject to detector performance. When the detector has communication delay or data loss, the host cannot effectively compensate for data or make intelligent judgments, forming a monitoring blind area. Second, the system linkage control capability is weak, and the host lacks a reverse control channel for the front-end devices, making it difficult to achieve intelligent linkage of fire warning and fire-fighting facilities (such as automatic power-off devices and emergency lighting systems). Third, the system has poor network expansion, and different manufacturers' devices have compatibility problems due to communication protocol differences. When new monitoring points are added, special lines often need to be re-deployed, significantly increasing construction costs and system complexity. SUMMARY

DETAILED DESCRIPTION

[0020] Figure 1 is the system structure schematic diagram of the utility model. Detailed Implementation

[0021] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, an electrical fire monitoring and management system includes: multiple electrical fire monitors, each electrical fire monitor including a host management module, a slave monitoring module, and a master-slave switching module. The host management module and the slave monitoring module switch the dominant control authority through the master-slave switching module. The host management module is used to manage and upload all collected electrical branch fire monitoring data, and the slave monitoring module is used to monitor fire data of multiple electrical branches. The slave monitoring module is communicatively connected to the electrical fire monitor whose dominant control authority is the host management module.

[0023] The electrical fire monitors in this utility model are uniformly designed, integrating master and slave functions. The master-slave switching module controls the switching of the dominant control authority of the electrical fire monitors. The working mode of the same electrical fire monitor is only one of master or slave. That is, the electrical fire monitors in the electrical fire monitoring and management system are either the electrical fire monitor with the master management module as the dominant control authority or the electrical fire monitor with the slave monitoring module as the dominant control authority.

[0024] When the electrical fire monitor is used as the host management module with the primary control authority, i.e., when the working mode is host, the address needs to be configured as a host-specific address, the device type needs to be configured as host type, and a polling mechanism needs to be enabled. Multiple detectors are connected via a 485 line, and the Modbus protocol is used to sequentially read and write data to the connected detectors. This achieves orderly management while ensuring stable and efficient data transmission.

[0025] When the electrical fire monitor is used as the master control module and the slave monitoring module is in slave mode, the address is configured in sequence, the device type is configured as slave, the polling mechanism is turned off, and it connects to the master and waits for the master to give commands to perform the corresponding operations.

[0026] The slave monitoring module includes a slave controller and multiple detectors. The slave controller is electrically connected to each detector, collecting and aggregating monitoring data from each detector. The master management module communicates with the slave controller in the slave monitoring module via the RS485 communication protocol. By connecting multiple slaves to a single master unit, fire data from multiple electrical branches can be managed simultaneously, reducing the lag and dispersion of data acquisition in the monitoring network.

[0027] The master-slave switching module is internally provided with an address configuration module for configuring the address of the electrical fire monitor. The address of the electrical fire monitor includes a master-specific address and a slave ordering address. The setting of the address ensures that the cloud can distinguish the working mode of the electrical fire monitor in the system. The cloud and the working mode are in communication connection with the master management module and the master-slave switching module in the electrical fire monitor serving as the master, collect the data collected by the master management, issue instructions to the master management module of the master, and then convey the instructions from the master to the slave monitoring module of the plurality of slaves connected to the master. When the working mode of a certain electrical fire monitor in the system needs to be switched due to actual needs, the cloud or the master receiving the instruction from the cloud transmits the master-slave switching instruction to the corresponding master-slave switching module, so that the working mode is switched, and the address is changed accordingly after the switching, and the system updates the address. Since the electrical fire monitor in the utility model is uniformly designed, the functions and communication protocols can still be quickly adapted and connected after switching, thereby greatly increasing the expansibility and usability of the fire monitoring networking.

[0028] The master-slave switching module is internally provided with a polling module for acquiring the detector data of the electrical fire monitor with the master control authority as the master management module. When the working mode is the master, the master management module sequentially performs data reading, writing and other operations on the connected detectors, and acquires the electrical branch fire monitoring data.

[0029] The types of the electrical branch fire monitoring data include current, voltage, residual current, temperature, power, balance degree, power factor and sensor short-circuiting and the like. Correspondingly, the plurality of detectors in the slave monitoring module include a current sensor, a voltage sensor, a residual current sensor, a temperature sensor and the like. The current sensor is used for detecting the current data of the electrical line. The voltage sensor is used for detecting the voltage data of the electrical line. The residual current sensor is used for detecting the residual current data of the electrical line. The temperature sensor is used for detecting the temperature data of the environment. Through the combined use of the sensors and the related technical means, the frequency data of the voltage and the power data of the electrical line can be monitored. The model of the detector involved in the utility model is not specifically limited. The detector type is welded on the hardware according to the actual functional needs of the user, and the corresponding functions are realized after being connected through electrical connection. The implementation mode of the detector function is all prior art.

[0030] The slave monitoring module further includes a fault arc sensor. The fault arc sensor is used for detecting the fault arc data of the electrical line.

[0031] The electrical fire monitor is provided with a display module and an interactive module. The display module can be an LCD display screen, and the interactive module can be a physical button with corresponding functional instructions. The voltage, current, residual current, temperature data and generated alarm fault records can be displayed on the screen in real time, and the data interaction with the device can be realized through the operation of the four physical buttons on the screen.

[0032] The electrical fire monitor is provided with an alarm module, which is used to send an audible and light alarm signal when the electrical branch fire monitoring data exceeds a set threshold value. The electrical fire monitor performs real-time alarm monitoring on the fire data of the electrical branch, the host management module polls alarm information of the connected slave monitoring modules, when a certain monitoring data of a certain slave monitoring module exceeds a set threshold value, corresponding alarm information is uploaded, the alarm information is summarized to the host management module of the corresponding host, and the host management module controls to generate an audible and light alarm.

[0033] The electrical fire monitor is provided with a wired network interface and a UPS interface.

[0034] The slave monitoring module is provided with a correction module, which calibrates the detector.

[0035] The above-mentioned embodiments only express several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
