DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a configuration and an operation of an embodiment of the present invention will be described with reference to the accompanying drawings, and the configuration and operation of the present invention shown in and described by the drawings will be described as at least one embodiment, The technical idea of the present invention and its essential structure and action are not limited.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a fire extinguisher remote management system according to the present invention, which shows a system for remotely managing fire extinguishers disposed at multiple points.

Referring to Figure 1, the fire extinguisher remote management system according to the present invention is a plurality of fire extinguishers (10A to 10K, 20A to 20M, 30A to 30N) and repeaters (11, 21, 31), and the operation of each group network It consists of a management server (40). Here, the configuration of each fire extinguisher will be described with reference to FIG. 2.

Each fire extinguisher 10A to 10K, 20A to 20M, and 30A to 30N have unique identification information, and sensors for detecting the state of the fire extinguisher such as the state of the extinguishing agent contained in the fire extinguisher container or the pressure inside the fire extinguisher, and the sensors And a transmitter for transmitting information relating to the results detected by the fire extinguisher life counted by the internal timer. The details of these fire extinguishers 10A-10K, 20A-20M, 30A-30N are demonstrated with reference to FIG.

Meanwhile, in the present invention, multiple fire extinguishers 10A to 10K, 20A to 20M, and 30A to 30N form a group network by repeaters 11, 21, and 31 for efficient data transmission.

That is, a plurality of fire extinguishers 10A to 10K, 20A to 20M, and 30A to 30N are classified into group units, thereby forming one group network by one repeater.

1 shows an example of forming three group networks, wherein the first repeater 11 forms a first group network including fire extinguishers 10A to 10K, and the second repeater 21 includes fire extinguishers 20A to The example which forms the 2nd group network containing 20M) and the 3rd repeater 31 forms the 3rd group network containing fire extinguisher 30A-30N is shown.

The first to third repeaters (11, 21, 31) collects the data transmitted from the fire extinguishers belonging to its group network, and transfers the collected data to the operation management server (40). Here, the data collected from the fire extinguishers belonging to the group network includes the state detection result detected by the sensor and information related to the fire extinguisher life counted by the internal timer.

In particular, the first to third repeaters (11, 21, 31) may wirelessly transmit the collected data directly to the operation management server (40). However, the present invention also performs more efficient data transmission through signal relay between adjacent network groups. That is, in the present invention, data transmission between the repeater and the operation management server 40 supports both the transmission method by direct communication and the transmission method by relay communication.

However, in the present invention, the transmission method by the relay communication is applied as a default, but when the communication is disconnected between the repeaters, the transmission method is directly transmitted to the operation management server 40 at the final relay step.

In the example of FIG. 1, the first repeater 11 relays the collected data to the second repeater 21, and the second repeater 21 transmits its own second data to the data received from the first repeater 11. The data collected in the group network is added and relayed to the third repeater 31. Then, the third repeater 31 adds the data collected from the third group network to the data received from the second repeater 21 and transmits the collected data to the operation management server 40. As a result, the data received from the third repeater 31 by the operation management server 40 includes all of the data collected by the first to third repeaters 11, 21, and 31. On the other hand, each fire extinguisher is given a unique identification information, each fire extinguisher identification information is included in the information transmitted to the repeater. Accordingly, the operation management server 40 may determine the individual state of the fire extinguisher by parsing the data received from the third repeater 31.

However, if the wired / wireless communication environment between the first repeater 11 and the second repeater 21 is poor and the second repeater 21 does not receive data from the first repeater 11, the first repeater 11 ) Transmits only the data collected from its first group network to the operation management server 40, and the second repeater 21 relays the data collected from its second group network to the third repeater 31. . Then, the third repeater 31 adds the data collected from the third group network to the data received from the second repeater 21 and transmits the collected data to the operation management server 40.

As another example, if the wired / wireless communication environment between the second repeater 21 and the third repeater 31 is poor and the third repeater 31 does not receive data from the second repeater 21, the second The repeater 21 adds the data collected from its second group network to the data received from the first repeater 11 and transmits the data to the operation management server 40, and the third repeater 31 has its third Only data collected in the group network is transmitted to the operation management server (40).

In the above, it is determined whether communication between the repeaters is possible from the reception of the ACK signal. That is, the first repeater 11 receives the ACK signal from the second repeater 21 within a predetermined time after transmitting data to the second repeater 21. In addition, the second repeater 21 receives the ACK signal from the third repeater 31 within a predetermined time after transmitting data to the third repeater 31. If the ACK signal is received within a predetermined time, it is determined as normal transmission, while if it is not received within a predetermined time, it is determined as abnormal transmission. As described above, when abnormal transmission occurs between relays, data transmission is smoothly performed by additionally employing a direct communication method as a transmission method by relay communication.

As described above, the present invention adopts a transmission method based on relay communication between several group networks, and relays perform signal relay between adjacent group networks, thereby providing status detection information and life related information for each fire extinguisher. Pass in 40.

The operation management server 40 individually controls the fire extinguisher based on the data received from the repeater 11 or 21 or 31, that is, the result detected by the sensor provided in the fire extinguisher and the life extinguisher life information counted by the internal timer. Perform

On the other hand, the communication between the fire extinguisher and the repeater, or between the repeaters, or between the repeater and the operation management server may be connected by wire or wireless communication. However, hereinafter, it is described that the wireless communication scheme is adopted, and examples thereof include Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Bluetooth (Bluetooth), and Amplitude Modulation (AM). , RF (Radio Frequency) of FM (Frequency Modulation) modulation scheme may be applied.
