The available sensor information includes the number of sensor nodes and identifiers, the type and weight of sensor nodes , Status and installation time information. And available unit information may include personnel information, previous operational performance and status information for each operable unit.

Table 1 shows an example of the field information that can be included in the available sensor information, available terminal information, and incident information stored in the resource DB 100.

The resource DB 100 can update available terminal information, available sensor information, and available bag information in real time according to information applied from the command control unit 200 or at least one portable terminal 300, It is possible to update at least one portable terminal 300 and at least one sensor node 400 and personal information in association with each other according to the status of the deployment operation. For example, when the command DB 200 selects a unit to execute an operation for arranging a sensor node together with a sensor node to be arranged from the available sensor information in the command and control unit 200, And the corresponding manpower information of the available bag information. Also, the identifiers of the portable terminals corresponding to the manpower information and the available terminal information are matched with each other so that the statuses are changed together, so that the statuses of the respective information are changed organically in the same operation. In addition, the resource DB 100 matches availability information and available sensor information with map information about an operation area where the sensor node is to be arranged, and matches the movement path of the unit that performs the operation with the placement position of each sensor node.

Meanwhile, the resource DB 100 can receive and store the sensor node layout plan and the sensor node layout status information from the command and control unit 200.

The command and control unit 200 sets up a sensor node arrangement plan, transmits the set sensor node arrangement plan to at least one portable terminal, communicates with at least one portable terminal 300 and at least one sensor node 400 Monitoring the situation where the sensor node is disposed, performing communication with the deployed sensor node after the sensor node is deployed, and performing unmanned ground surveillance by operating the sensor node.

When the subordinate identifier is input as user information, the input subordinate identifier is guided along with the identifier of the portable terminal To the control unit 200, and notifies that the corresponding portable terminal is assigned to the corresponding member. The command and control unit 200 may transmit the transferred subscriber identifier and the identifier of the portable terminal to the resource DB 100 so that the identifier of the portable terminal corresponding to the available information of the portable terminal matches the information of the portable terminal.

At least one portable terminal 300 may communicate with the command and control unit 200 to receive a sensor node allocation plan. In some cases, the sensor node deployment plan may be transmitted via a separate recording medium. At this time, each of the at least one portable terminal 300 may receive the entire sensor node allocation plan, but only some information corresponding to the current user in the sensor node allocation plan may be received. The portable terminal 300 displays a map corresponding to the received sensor node layout plan and the sensor node layout plan so that the user can recognize the operation to be performed by the user. In addition, the current location information including the location information confirmation function such as GPS can be displayed on the map displayed on the screen and transmitted to the command and control unit 200.

In particular, in the present invention, at least one portable terminal 300 can perform a check on a sensor node by performing communication with at least one sensor node 400 to be disposed at a designated position according to the sensor node placement plan. That is, the sensor node 400 may be pre-checked to prevent the occurrence of an error in the sensor node allocation plan due to the failure of the sensor node or the like.

At least one sensor node 400 performs a target detection operation in a designated manner and transmits a detection signal to the command and control unit 200 when a target is detected. Here, the at least one sensor node 400 may have the same detection method or may have different detection methods.

In the monitoring mode, at least one sensor node 400 detects the target and transmits a detection signal to the command control unit 200, while in the test mode, the sensing signal is transmitted to at least one portable terminal 300 send.

2 illustrates a method of arranging and operating a sensor node in an unmanned ground monitoring sensor node system according to an embodiment of the present invention.

Referring to FIG. 1, the method for arranging and operating the unmanned terrestrial monitoring sensor node in FIG. 2 will be described. First, the command and control unit 200 sets a sensor node allocation plan in response to a user command, The plan is called up, corrected and set, and the set sensor node layout plan is transmitted to at least one portable terminal (S100). Here, the sensor node placement plan may include information on the location of the sensor node, such as surveillance zone information, deployment operation information, operation start time, and cluster information.

At least one portable terminal checks at least one sensor node 400 to be placed based on the transmitted sensor node placement plan, displays a movement path and a return path to a placement position of the sensor node, The command and control unit 200 can monitor the execution state of the batch operation, and each sensor node displays the placement position and the placement direction so that the sensor node is designated at a designated position (S200).

After that, the command and control unit 200 communicates with at least one sensor node 400 disposed in a designated direction in the detection direction, and operates the unmanned aerial surveillance system in operation S300. The command and control unit 200 communicates with at least one sensor node to monitor whether or not a target is generated for the monitoring area and also determines whether an error occurs in the sensor node in operation based on the communication state with the sensor node Perform monitoring tasks.

If it is determined that the sensor node needs to be replaced due to an abnormality in the sensor node, the sensor node collection plan is set based on the sensor node layout plan, The nodes are collected, checked for repair and managed (S400).

FIG. 3 is a detailed view of the sensor node layout plan setting step of FIG. 2. FIG.

In the sensor node allocation plan setting step, the resource DB 100 first obtains available resource information (S110). As described above, the resource DB 100 collects and stores available terminal information, available sensor information, available bag information, and map information as available resource information, and transmits the collected information to the command control unit 200 or the at least one portable terminal 300, And updates the available terminal information, available sensor information, and available bag information in real time.

 The command and control unit 200 displays the available resource information collected in the resource DB 100 in response to the sensor node placement plan setting command applied by the user command, A layout plan is generated (S120). The command and control unit 200 can set the arrangement area information, the arrangement object information, the operation start time information, and the collection point information, in which the sensor node is to be arranged first. Table 2 shows an example of setting items of the batch operation information.

The command and control unit 200 may first call the map information in the resource DB 100 to display the called map and set the area selected on the displayed map as the location area information according to the user command.

On the other hand, the placement object information can be set by selecting a location where the sensor node is placed in the selected area of the map on which the collected information is displayed according to the sensor node placement purpose. In this case, the purpose of deploying the sensor node can be set in response to a user command, which is classified as an attack purpose or a defense purpose. In the case of an attack, the collected information displayed in the map selection area may be enemy position and danger area information, For defensive purposes, it may be friendly defense area information and defensive facility information.

When the placement area in which at least one sensor node 100 is to be placed is selected from the displayed map information according to the purpose of placement of the sensor node, the command and control unit 200 determines the time and location at which the unit, The operation start time information and the collection site information.

When the sensor node placement plan is generated, the command and control unit 200 selects at least one sensor node 400 to be placed in the placement region region, sets the placement position and the placement direction of each selected sensor node, (S130). Table 3 shows an example of the sensor node property setting items.

As shown in Table 3, each of the at least one sensor node 400 is different from the sensing method and the sensing direction and the sensing range according to the type and the characteristic. Therefore, if all the sensor nodes are arranged in accordance with a rule set in advance in a collective manner, the unmanned terrestrial sensing performance is greatly deteriorated. When the at least one sensor node 400 to be placed in the deployment area is selected, the command and control unit 200 displays the sensing method, the sensing direction, and the sensing range together with the selected sensor node. In response to the user command, the position and direction of the selected sensor node are adjusted and arranged at a designated position within the placement area displayed on the map. That is, the user can easily set the placement position and the placement direction in consideration of the characteristics of each sensor.

When the arrangement position and direction of each sensor node is set, the command and control unit 200 determines the position and orientation of each sensor node based on the arrangement area, the collection point information, the operation start time, Detailed operation information is set (S140).

The command and control unit 200 receives and displays operational information that can be executed from the resource DB 100, and selects a unit to perform an operation in response to a user command. Here, the command and control unit 200 may analyze at least one unit suitable for the operation by analyzing the information of the members of each unit, the type, quantity, weight, and movement path of each sensor to be deployed. Table 4 shows an example of detailed operational information setting.

As shown in Table 4, the command and control unit 200 can set the limit weight and the movable distance of the sensor node that can be held per each party, and can display the number and placement range of sensor nodes that can be installed in each unit . The number of sensor nodes to be placed by each group is within the limited weight, and each sensor node arrangement task is divided into a plurality of sensor node groups (for example, And the time to be completed is set as uniform as possible. Here, the time at which the batch operation is completed can be calculated by adding the installation time of each sensor node of the movement time according to the movement route. In addition, when grouping, it is possible to classify each unit as to make the installation ability of each sensor node as equal as possible by taking into consideration whether or not there is experience of deploying previous sensor nodes, and rank.

When detailed operation information is set, the command and control unit 200 analyzes precautions to be taken during the sensor node placement operation and includes it in the sensor node placement plan (S150). These precautions may include landmine burial areas, enemy landing areas, and hazardous terrain information.

If the attention information is included in the sensor node placement plan, the command control unit 200 transmits the set sensor node placement operation to the portable terminal 300 that is provided to the unit for performing the sensor node placement operation (S160). The sensor node placement operation can be transmitted to and stored in each group of portable terminals and only the operation contents corresponding to the operation to be performed in each group can be transmitted instead of the entire sensor node placement operation. And in some cases may be delivered via a separate memory device rather than through wireless communication.

When the sensor node to be deployed and a unit to perform an operation are determined and then the command and control unit 200 transmits the selected sensor node information and the manpower information to the resource DB 100 so that the identifier of the sensor node and the manpower information Match it. Also, the command and control unit 200 may transmit the identifier of the at least one portable terminal 300 to the resource DB 100 to be matched with the manpower information. At least one portable terminal 300 to be provided to the unit may be arbitrarily selected by the command and control unit 200. However, if the portable terminal 300 has been paid in advance to each unit, And may be stored in the resource DB 100. Also, when a portable terminal is newly provided to each unit, personal information may be input through the paid portable terminal, so that the identifier of the portable terminal and the personal information may be matched.

FIG. 4 is a detailed view of the sensor node field arrangement management step of FIG. 2. FIG.

In the sensor node field layout management step, at least one portable terminal 300 displays the sensor node layout plan transmitted and stored in the command and control unit 200 (S210). That is, each member who performs the sensor node placement plan can confirm the sensor node placement plan. At least one portable terminal 300 displays the matched group member information so that it can be confirmed whether the payment has been made in accordance with the set specified in the portable terminal 300. The types, identifiers, and quantities of the sensor nodes to be disposed are displayed in each group Allows you to identify the sensor node to be paid for deployment. And displays the travel route, the expected travel time, the start time of the operation, and the precaution, etc., so that the sensor node placement plan can be recognized in advance so that it can be safely performed within the designated time. Table 5 shows an example of the details of the sensor node placement plan displayed on the portable terminal 300.

Thereafter, at least one portable terminal 300 communicates with at least one sensor node 400 to be placed in the deployment area to check whether the sensor node performs a normal operation (S220). At least one portable terminal 300 provided to each group performs communication with a sensor node to be placed and confirms whether the sensor node performs a normal operation or receives an identifier of the sensor node to perform a normal operation Can be confirmed.

At this time, at least one portable terminal 300 can set the sensor node to a test mode or a monitoring mode, and it can receive the operation information of the sensor node in the test mode and confirm whether the sensor node is operating normally. Here, setting the sensor node to the test mode is performed by transmitting a detection signal generated at the sensor node to the command and control unit 200 during a check operation performed to determine whether the sensor node is operating normally, It is for this reason.

At least one portable terminal 300 analyzes whether sensing information corresponding to detection information artificially generated by a member of a team or the like is generated and transmitted in the sensor node set in the test mode, transmits a predetermined control command to the sensor node, It is possible to determine whether the sensor node is normal or not by analyzing whether an acknowledgment corresponding to the command is transmitted.

The at least one portable terminal 300 transmits the location information of the portable terminal 300 to the command and control unit 200 while the sensor node placement planning is performed from the collection site to place the sensor node, The unit 200 receives the location information and monitors the movement status of each of the plurality of sensor nodes (S230). Also, when at least one portable terminal 300 arrives at a designated position in which the sensor nodes are moved, the sensor nodes are arranged to be disposed and the placement direction and the placement direction are arranged so that the sensor nodes are arranged easily. Also, the user can input the arrangement item data from the user and transmit the arrangement data to the storage and command controller 200.

The at least one portable terminal 300 or the command and control unit 200 activates the deployed sensor node in the test mode and communicates with the activated sensor node to monitor the normal operation and normal deployment of each sensor node (S240). The command and control unit 200 checks the number of sensor nodes that have been checked for normal operation and normal placement at the designated placement position so far as the total number of sensor nodes to be placed, Or a graph or the like. At this time, the command and control unit 200 can check whether the sensor node placement plan is delayed and the estimated time when the sensor node placement plan is completed by comparing the scheduled time and the current progress ratio in the sensor node placement plan that is not performed have.

At least one of the portable terminal 300 and the command and control unit 200 determines whether all of the sensor nodes set in the sensor node placement plan are located (S250). If it is determined that all the sensor nodes are located, it is checked whether the position of the portable terminal 300 has returned to the collection place (S260). In other words, check whether the unit returned safely.

5 is a detailed view illustrating a sensor node operation management step of FIG.

4, the command and control unit 200 activates all the deployed sensor nodes in the surveillance mode to perform the unmanned ground surveillance operation after all the sensor nodes are disposed or returned to the site. That is, the sensor node is operated to monitor the placement area (S310). The command and control unit 200 analyzes the detection signal transmitted from the deployed sensor node to determine whether or not the target has entered.

Meanwhile, the command and control unit 200 determines whether or not an abnormality has occurred in the sensor node disposed during the unmanned aerial surveillance operation (S210). The command and control unit 200 may transmit a warning message such as an abnormal signal such as an excessive detection signal or a battery exchange request from the sensor node or transmit a control signal to the sensor node, If it is determined that the sensor node has occurred, the corresponding sensor node is deactivated and a sensor node replacement request is displayed.

The command and control unit 200 sets up a sensor node layout plan in response to a user command applied according to the sensor node replacement request indication (S340). Then, the replacement plan is transmitted to the portable terminal of the member who performs the replacement operation so that the sensor node having the abnormality is collected and the other sensor node is arranged according to the set replacement plan, and the portable terminal displays the travel path, (S350). At this time, the portable terminal can perform the operation check in advance for the sensor node to be newly disposed. In addition, when a warning such as a low battery is generated, only the battery other than the sensor node may be displayed to be replaced.

In operation S360, the command and control unit 200 checks whether the replaced sensor node is located in the designated position and direction, activates the replaced sensor node in the monitoring mode, and performs the unmanned ground monitoring operation together with the existing sensor nodes.

On the other hand, the command and control unit 200 analyzes the position of the portable terminal, confirms return of the member who performed the replacement operation, transmits information of the collected sensor node and the newly disposed sensor node to the resource DB 100, (S370). In this case, the collected sensor node is the sensor node in which the abnormality occurs, so it can be stored in the state of the sensor node as being under repair or the like.

FIG. 6 is a detailed view of the sensor node collection management step of FIG. 2. FIG.

In the sensor node collection management step, the command control unit 200 first determines whether the unmanned terrestrial monitoring mission for the deployment area in which the sensor node is located is terminated (S410). If it is determined that the unmanned ground surveillance mission is terminated, the command delivery unit 200 sets up a sensor node collection plan (S420). The sensor node collection plan can be set by the command and control unit 200 in response to a user command in a manner similar to the sensor node placement plan. However, since the sensor node collection plan is in a state in which the sensor node is already disposed in the deployment area, unlike the deployment plan, only the unit for performing the collection operation and the operation start time information and the cluster information may be set. The troops that carry out the collecting operation here are preferably set to the same unit as the unit that carried out the deployment operation, but other units may be set.

Then, the sensor node collection plan is transmitted to the portable terminal of the unit performing the collection operation, and the movement path and the position of the sensor node to be collected are displayed (S430). The portable terminal transmits the position information to the command and control unit 200 during the movement so that the command and control unit 200 can monitor the sensor node collection status at step S440.

When the collection of the sensor nodes is completed, the command and control unit 200 confirms that the unit performing the collection operation returns to the collection site, and the portable terminal 300 operates the collected sensor nodes in the test mode to check the status of the sensor node , And transmits the check result to the command and control unit 200 (S450).

The command and control unit 200 transmits the check result of the collected sensor node to the resource DB 100 to update the information of the resource DB 100 (S460)
