Description
Technical Field
The invention relates to the field of fire fighting, in particular to a fire fighting management system.
Background
When a fire occurs, the on-site fire protection system cannot immediately notify related personnel to go to rescue, which can lead to serious work safety incidents. Therefore, there is a need to build fire protection systems that can be immediately managed.
The existing fire fighting system can be divided into a traditional (P type) central office and an intelligent (R type) central office. The difference between the traditional credit exchange and the intelligent credit exchange is as follows:
traditional credit exchange: as shown in fig. 1a, the conventional credit exchange is of a loop type, each loop is connected to a set of devices 10, wherein each set of devices 10 is composed of a plurality of sensors, such as a fire alarm sensor 12, a fault sensor 14, a smoke detection sensor 16, and a power failure sensor 18. Taking the conventional credit exchange as an example, each conventional credit exchange can be connected to about 200 loops, that is, 200 sets of devices 10 are connected, and the signal of each set of devices 10 is transmitted to the credit exchange 20 by a solid line connection. When a particular set of equipment 10 is triggered (e.g., a fire alarm occurs), the central office 20 receives the corresponding loop signal and issues an alarm 30 to notify the relevant personnel to identify which sensor within the set of equipment is experiencing the problem.
Intelligent credit exchange: as shown in fig. 1b, the intelligent central office may transmit the signal of each sensor, such as the fire sensor 12, the fault sensor 14, the smoke sensor 16, and the power failure sensor 18, in the equipment 10 to the central office 20 through the network communication card and/or the module card in a network transmission manner, so that the central office 20 may scan the status of each sensor in all the equipment 10. When the respective sensor is triggered, the credit exchange 20 immediately sends out an alarm, and the management and control unit 40 notifies the person associated with the sensor to go to rescue.
The problems of the traditional credit exchange and the intelligent credit exchange are as follows:
for the conventional credit exchange, each set of equipment includes a plurality of sensors, and as long as one of the sensors fails or is triggered, the equipment will transmit a signal to the exchange and send an alarm, so that the dilemma that the alarm is frequently triggered but which sensor fails to be known immediately occurs will occur. In addition, because the wiring loops of the traditional credit exchange must be returned to the credit exchange, compared with the intelligent credit exchange, the wiring is wasted, and extra manual wiring and cost are required, and when the system has a problem, the line inspection cost of the traditional credit exchange is higher than that of the intelligent credit exchange. For the intelligent credit exchange, the current central control unit can not know the increase or decrease of the sensors from the transmitted signals. For example, if the newly added fire sensor is not reported to the central control unit, when a fire occurs and the newly added fire sensor is triggered, the central control unit cannot know the overall situation, so that the relevant person cannot be dispatched to rescue.

According to an aspect of an embodiment of the present invention, there is provided a fire management system. Fig. 2a is a schematic block diagram of a fire management system according to an embodiment of the present invention. Referring to fig. 2a, the fire management system 1000 includes a credit exchange 200. The credit exchange 200 is electrically connected to at least one device 100. The credit exchange 200 may be connected to the equipment 100 through a physical signal transmission line, and the equipment 100 may include a plurality of sensors, such as a fire sensor 102, a fault sensor 104, a smoke sensor 106, and a power failure sensor 108.

Referring to fig. 6a, a first device of the first loop, i.e., a sensor Detector L1D1, is illustrated. Each Address (Address) has a corresponding Tag Name (Tag Name) and Description (Description). Information such as device name, floor, system identification, etc. may be substituted into the Tag (Tag). For example, address 40001.10 corresponds to a tag name of K23_ B2F _ BMS _ ALM _ Detector _ L1D1_ ENB, which states that K23B 2F fire protection system alarm sensor L1D1 is enabled. Referring to FIG. 6b, the device status may be determined according to the obtained data Value, for example, according to the item ID (item ID) with the data Value (Value) of 1, the device status may be detected (IACT) and Enabled (ENB).
In some embodiments, the Kepware empty point totals may be established as corresponding tags. When building a site, information such as the device name, floor, system type, etc. may be substituted into the Tag (Tag). The JOB program is written so that the Kepware host can fix the device signals of all the dots scanned daily to confirm the device addition or removal status.
In some embodiments, the management unit may determine the addition or removal status of the device by comparing the scanned device signal with a Mapping (Mapping) table of the original on-line device.
Specifically, as shown in fig. 7, the device list scanned on the current day is compared with the online device mapping table, and if the device list scanned on the current day is not matched with the online device mapping table, a device transaction is detected (S702). It is then determined whether there is a device removal (S704). If the setting value of 255 occurs from bit 0 to bit 7, it means that there is a device removed.
If it is determined that no device is removed (S704). If the scanned list of devices is compared with the on-line device mapping table, and the new device is found, it is determined at S706 whether the new device is displayed for a certain period of time (e.g., three days) (the new device signal that can be scanned in two days may be only the device that has been set by the on-line host but is not installed in the field, or the device that is still under test).
If it is determined at S704 that the device is removed or it is determined at S706 that the newly added device is detected for three consecutive days, the service person in charge of the management and control unit may ask the relevant fire person to issue a response sheet (S708), which is why the fire person responds to the removal of the device (S710). The mapping table of the device online device may be updated by the service responsible person (S712), confirmed by the fire responsible person (S714), and then a single contingency may be replied to (S716). Therefore, the new and removed states of the equipment can be detected by increasing the scanning of all the equipment every day and using the setting values of the bits 0 to 7 of the equipment signals, thereby realizing the management of all the states of the equipment in a centralized management mode.
The fire-fighting equipment management system provided by the invention is improved aiming at the traditional credit exchange and the intelligent credit exchange, so that the control unit can immediately know the fire-fighting management condition of each equipment, the traditional distributed management mode is changed into the centralized management mode of the control unit, and the advantages of real-time detection, automatic notification and systematic management of faults, fire events and equipment addition or removal can be achieved.
