As shown in FIG. 1, the facility management system according to the first embodiment of the present invention uses a plurality of detection sensors 100 for detecting state data of facilities and information detected by the plurality of detection sensors 100. The management device 200 for analyzing and processing the same, the interface 300 for providing a result processed by the management device 200 to a user, and relaying data transmission / reception between the detection sensor 100 and the management device 200. It is configured to include a gateway 400.

Here, the plurality of detection sensors 100 is installed in a wide area at the main part of the main facility of a predetermined area. Therefore, each detection sensor 100 can detect various data regarding the installed facility.

The plurality of detection sensors 100 as described above not only detects the state of the installed facilities by configuring the sensor node in the sensor network and the node detection sensor 110 for detecting the state of the installed facilities by configuring the sensor node in the sensor network, The node detection sensor 110 and the gateway 400 is divided into a reference node detection sensor 120 for relaying data transmission and reception.

To this end, each of the plurality of sensing sensors 100 is measured by measuring the communication environment (including whether the communication with the surrounding sensing sensor and the communication quality) with respect to the surrounding sensing sensor sharing the same small block ID Save and broadcast your environment.

Each of the plurality of sensing sensors 100 sets a reference node by referring to the collected communication environment by collecting the measured communication environment broadcasted from the surrounding sensor that share the same small block ID.

Subsequently, each of the plurality of sensing sensors 100 that set the reference node as described above performs data transmission and reception via the set reference node when transmitting and receiving data with the management apparatus 200.

The sensing sensor set as the reference node among the plurality of sensing sensors 100 notifies the fact to the gateway so as to transmit and receive data via itself when transmitting and receiving data with other sensing sensors.

Meanwhile, the plurality of detection sensors 100 transmit and receive data by passing through the reference node when transmitting and receiving data with the gateway 400.

In this case, when it is difficult to directly transmit / receive data with the reference node, the plurality of detection sensors 100 transmit and receive data via the hopping node using another detection sensor having excellent communication environment as a hopping node. do.

Meanwhile, the management device 200 may include a server unit 210, a database 230, and a data processor 220.

On the other hand, when the hopping setting unit 60 is difficult to directly transmit and receive data with the reference node, it sets another detection sensor having excellent communication environment in the surrounding as the node detection sensor for hopping.

As such, when the surrounding detection sensor is set as the hopping node detection sensor, the hopping setting unit 60 notifies the fact that the node is configured as the hopping node detection sensor so that the hopping node detection sensor can relay the data.

In such a configuration, as another embodiment, the communication environment test unit 10 tests a communication speed with respect to detection sensors that share the same small block ID of the surroundings. At this time, the communication environment test unit 10 may measure the network speed by transmitting and returning a ping signal or by uploading and downloading a file of a specific size to measure the network speed.

In addition, the communication environment test unit 10 creates a test result of the communication speed into a table as shown in FIG. 5 (in FIG. 5, a table value is a value obtained by converting a network speed between nodes into a predetermined time value). ) Is stored in a memory (not shown), and the test result is passed to the test result broadcaster 20 to broadcast to a sensing sensor sharing the same small block ID.

In addition, the communication environment test unit 10 receives data from the same small block ID of the surroundings, measures the communication speed, stores the table created by preparing the measured communication speed as a table, and stores the test result in the test result broadcast unit 20. ) And broadcast it to a sensor that shares the same small block ID.
