METHOOD, SYSTEM, AND COMPUTER-READABLE RECORDING MEDIUM FOR SUPERVISING REAL-TIME FIRE USING ZIGBEE WIRELESS COMMUNICATION}

The present invention relates to a method, system and computer readable recording medium for fire monitoring using ZigBee wireless communication technology. More specifically, methods, systems, and computer readings for fire monitoring using ZigBee wireless communications technology installed within wireless sensors that monitor the status of multiple wireless sensors and distribution panels in real time and quickly respond to fires to prevent fires. It relates to a possible recording medium.

In recent years, as the industrialization is advanced, the elements of improved fire are increasing due to the irregular energy use and the sharp increase in the use of electricity in high-rise office buildings, complex industrial factories, apartments, and houses. In particular, in the case of a multi-use building such as a multi-purpose building and a department store, the fire occurrence factor is higher, and when a fire occurs, many people suffer from damage to human and physical properties due to residence and transportation.

Representative fire generating factors include overload, short circuit, and contact heating due to the increase of electricity consumption. When an overload, a short circuit, contact heating occurs in this way, it is necessary to quickly detect the fire to prevent the spread of the fire. To this end, conventionally, a wireless sensor is installed where a fire may occur, and a fire monitoring system for monitoring a fire condition is established by checking information related to a fire-prone factor transmitted through a wireless sensor network.

However, the conventional fire monitoring system does not accurately understand the state parameter of the fire sign, and the routing technique of the wireless sensor network (commonly referred to as ad-hoc routing technique as the routing technique of the wireless sensor network) is related to the fire occurrence. Inefficient aspects such as loss of information, delay, high power consumption, etc. caused a failure to monitor the fire condition in real time.

For example, a typical conventional ad-hoc routing technique applied between wireless sensors is a planar routing technique. Conventional request-based hierarchical routing techniques include Direct Diffusion, Sensor Protocol for Information via Negotiation (SPIN), Sequential Assignment Routing (SAR), Minimum Cost Forwarding Algorithm for Sensor Networks, etc. It is classified in a table-based manner. However, the on-demand planar routing technique generates path request messages for hundreds to thousands of nodes to find a path, which consumes a lot of power energy, delays in information movement, and loss. There have been many problems in terms of efficient transmission of information related to occurrence.

On the other hand, table-driven planar routing techniques have limitations in keeping nodes of a wireless sensor route to nodes of numerous wireless sensors in a wireless sensor network. That is, since the memory capacity of the node of the wireless sensor is about hundreds of kilobytes, it is virtually impossible to maintain and manage a routing table with information about hundreds to thousands of nodes of the wireless sensor.

Therefore, a routing technique that accommodates a collection of information to reduce energy waste caused by the distribution of energy consumption and the overlapping transfer of similar information between nodes of adjacent wireless sensors in the process of transmitting collected information, and a method of reducing information loss and delay, etc. It is required.

Example Routing Process in a Wireless Sensor Network

4A and 4B illustrate an exemplary routing process in a wireless sensor network according to an embodiment of the present invention, in which a wireless sensor node includes four child nodes 510, 520, 530, and 540. Only when the parent node 550 that manages the child node will be described by way of example.

4A illustrates a state where node cost values of nodes 510, 520, 530, 540, and 550 of all wireless sensors are set to infinity before power is applied. At this time, a node of each wireless sensor is assigned a unique identification number (ID), which is exemplified by numbers 0 to 4. In FIG. 4B, when power is applied, nodes 510 to 550 of each wireless sensor are assigned a unique node cost value, and a unique link cost value may also be allocated between the nodes of two wireless sensors.

Thus, as shown in Figure 4b, the routing process in the wireless sensor network according to an embodiment of the present invention is optimal routing so that any child node to collect the collected fire monitoring information to the parent node detected by the object in any child node In the process of setting the path, the routing path is established using neighboring child nodes having a minimum total link cost value until the node cost value assigned to any child node is transmitted to the parent node. Will be chosen.

For example, if the child node 540 with identification number 4 selects an optimal routing path to carry stored fire monitoring information with parent node 550 with identification number 0, identification number 4 with a node cost of 40 The child node 510 selects the child node 520 having the identification number 2 having the minimum link cost value 10 among the connected links as the routing path 511. Subsequently, the child node 520 having the identification number 2 selects the child node 540 having the identification number 3 having the minimum link cost value 15 among the connected links as the routing path 521. Subsequently, the child node 540 having the identification number 3 selects the case where the neighboring node cost is small when the connected link has the same minimum link cost value, but here the actual parent node 550 having the identification number 0 is used. Since the final destination is the parent node 550 having the identification number 0 as the final routing path 540 it is possible to transmit the fire monitoring information.
