The management device 30 communicates with the communication device 10 via the management output unit 42b and the management reception unit 12a, and switches the communication device 10 to the mapping mode. When the mode is switched to the mapping mode via the management reception unit 12a, the output unit 12b of the communication device 10 temporarily reduces the output.

After disconnecting the communication with the communication device 10, the signal receiving unit 42a of the management device 30 receives the identification information output by the output unit 12b of the communication device 10 switched to the mapping mode. The first acquisition unit 43 of the management machine 30 acquires the identification information received by the signal reception unit 42a. The management machine 30 confirms whether the radio wave reception intensity of the identification information acquired by the first acquisition unit 43 is equal to or higher than a predetermined threshold value based on the threshold value stored in advance in the management storage unit 46.

To determine the point where the radio wave reception intensity (radio wave intensity) is equal to or higher than a predetermined threshold value, the field 3 is divided into a grid (mesh), and the radio wave intensity of each communication device 10 is compared for each mesh 3a. Specifically, as shown in FIG. 9, the management machine 30 is stored in the field information or the management storage unit 46 acquired from the storage unit 52 of the server 50 via the server output unit 51b and the signal receiving unit 42a. Move in the field 3 based on the field information. The reception strength of the identification information of each communication device 10 received by the signal receiving unit 42a is compared, and the position of the communication device 10 is estimated. For example, the numerical value in each mesh 3a shown in FIG. 3D indicates the radio wave intensity of the communication device 10 arranged at the B-3 point in each mesh 3a. In this case, it is presumed that the communication device 10 is installed at the B-3 point where the radio field intensity received by the management device 30 shows the maximum value.

As shown in FIG. 3A, when the management machine 30 is in the mapping mode, the position detection unit 41 detects a position at a point where the radio field intensity acquired by the first acquisition unit 43 is equal to or higher than a predetermined threshold value. The second acquisition unit 44 acquires the positioning information detected by the position detection unit 41.
The association unit 45 associates the positioning information at a point where the radio field intensity acquired by the first acquisition unit 43 is equal to or higher than a predetermined threshold value with the updated identification information. The association information (positioning information, identification information) is stored in the management storage unit 46. Alternatively, it is temporarily stored in the management storage unit 46 and transmitted to the server 50 via the management output unit 42b and the fourth acquisition unit 51a. The registration unit 53 of the server 50 associates the association information with the field information such as the field name and the field position and registers the association information in the storage unit 52.

The management machine 30 requests the communication device 10 for which the registration of the field information has been completed to update the identification information via the management output unit 42b and the reception unit 12a. The communication device 10 updates the identification information in response to the request of the management device 30.
After disconnecting the communication with the communication device 10, the management device 30 starts detecting the output of the other communication device 10. The management machine 30 determines whether or not the position information has been registered based on the updated identification information stored in the management storage unit 46 or the storage unit 52. That is, as shown in FIG. 3B, in the mapping mode, the management device 30 does not request the communication device 10 that outputs the updated identification information to be connected. In other words, the management device 30 requests a connection only to the communication device 10 that outputs the identification information before the update. The management machine 30 ends the mapping mode if there is no communication device 10 that outputs the identification information before the update.

In the present embodiment, the output unit 12b outputs the identification information and the notification information by radio waves, but may be such that the output unit 12b outputs by light. For example, the output unit 12b outputs a light emitting pattern indicating identification information of a plurality of communication devices 10. As shown in FIG. 3C, the position detection unit 41 detects positioning information at a point where the reciprocal of the horizontal distance between the light acquired by the first acquisition unit 43 and the first acquisition unit 43 is equal to or greater than a predetermined threshold value. The association unit 45 associates the positioning information at a point where the reciprocal of the horizontal distance between the light acquired by the first acquisition unit 43 and the first acquisition unit 43 is equal to or greater than a predetermined threshold value and the updated identification information. The association information is stored in the management storage unit 46. Alternatively, it is temporarily stored in the management storage unit 46 and transmitted to the server 50 via the management output unit 42b and the fourth acquisition unit 51a. The registration unit 53 of the server 50 associates the association information with the field information and registers them in the storage unit 52.

Next, the monitoring mode will be described. The monitoring mode detects dynamic abnormalities such as the invasion of a person who has invaded the field 3 and the invading animal. In this mode, the management machine 30 is dispatched to the detection location of the abnormality based on the position information. The instruction to switch to the monitoring mode is operated from the mobile terminal 60 or the like connected to the server 50.
Specifically, for example, as shown in FIG. 14, the monitoring button 103 of the home screen Q1 of the mobile terminal 60 or the like is selected. When the monitoring button 103 is selected, the monitoring status screen Q2 is displayed as shown in FIG. 16C. When the monitoring button 204 on the monitoring status screen Q2 is selected, the mobile terminal 60 instructs the server 50 to switch to the monitoring mode. The monitoring instruction unit 51b3 of the server 50 issues a switching instruction (monitoring instruction) to the monitoring mode to the management machine 30 via the signal receiving unit 42a and the server output unit 51b. The management machine 30 that has received the monitoring instruction stands by, for example, at a predetermined waiting place 3b such as around the field 3 shown in FIG. 2A. When the instruction to switch to the monitoring mode is completed, the screen display of the display unit 62 transitions to the home screen Q1 as shown in FIG.

The communication device 10 initializes the output of the output unit 12b and initializes the determination conditions. The physical quantity detection unit 11 starts detecting the physical quantity. The notification creation unit 12c determines whether or not the physical quantity detected by the physical quantity detection unit 11 meets any of the notification determination conditions.
When the first condition (quasi-danger) of the notification determination condition is met, the notification creation unit 12c creates the first notification information indicating that the notification is quasi-danger. The output unit 12b of the communication device 10 outputs the first notification information created by the notification creation unit 12c. When the second condition (danger) of the notification determination condition is met, the notification creation unit 12c creates the second notification information indicating that it is dangerous. If the second condition (danger) of the notification determination condition is met and the third condition (urgent) is not met, the output of the output unit 12b is initialized. The output unit 12b of the communication device 10 outputs the second notification information created by the notification creation unit 12c.

When the third condition (urgent) of the notification determination condition is met, the notification creation unit 12c creates the third notification information indicating that it is urgent. The communication device 10 confirms whether there is a connection request from the dispatch unit 20. When there is no connection request from the dispatch unit 20, the output unit 12b of the communication device 10 sets the output of the third notification information created by the notification creation unit 12c, and does not output the third notification information. The state in which the output unit 12b sets the output of the third notification information and does not output the third notification information is also referred to as "stealth mode".

When the fourth condition (ERROR) of the notification determination condition is met, the notification creation unit 12c creates the fourth notification information indicating that the ERROR has occurred. The output unit 12b of the communication device 10 outputs the fourth notification information created by the notification creation unit 12c.
If any of the notification determination conditions is not met, the output unit 12b of the communication device 10 sets the identification information. The output unit 12b outputs the identification information.

The output unit 12b of the communication device 10 outputs the first notification information, the second notification information, and the fourth notification information created by the notification creation unit 12c with different radio wave outputs. Specifically, the first notification information and the fourth notification information are output with a radio wave output smaller than that of the second notification information.
The second communication unit 21 of the dispatch unit 20 detects the notification information of the communication device 10. The call determination unit 21c determines whether the notification information is output. When the call determination unit 21c determines that the notification information is not output from any of the output units 12b of the plurality of communication devices 10, the signal reception unit 42a receives the activation information from the server 50 or the mobile terminal 60. Check if it is done. When the signal receiving unit 42a receives the activation information from the server 50 or the mobile terminal 60, the dispatching unit 20 starts detecting the communication device 10 that does not output the notification information. The dispatch unit 20 makes a connection request to the detected communication device 10. The communication device 10 that meets the third condition connects in response to the connection request. The second communication unit 21 of the dispatch unit 20 requests the communication device 10 to increase the output of the output unit 12b. If there is a request for the output of the output unit 12b to increase, the communication device 10 increases the output of the output unit 12b and outputs the third notification information from the output unit 12b. The second communication unit 21 disconnects the communication after the request for the increase in the output. The communication device disconnects the communication after confirming the request for the output of the output unit 12b to increase. When the communication device 10 determines that there is no request from the second communication unit to increase the output, the communication device 10 disconnects the communication.

If the notification information is not output from any of the output units 12b of the plurality of communication devices 10 and the activation information is not acquired, the call determination unit 21c determines that the management machine 30 is not called. ..
When the call determination unit 21c determines that the notification information is output from any of the output units 12b of the plurality of communication devices 10, the third acquisition unit 21a of the dispatch unit 20 acquires the notification information. .. When the third acquisition unit 21a determines that the third notification information has been acquired, the call determination unit 21c calls the third notification information based on the third notification information acquired by the third acquisition unit 21a due to an emergency. 3 Create call information.

If the notification information acquired by the third acquisition unit 21a is not the third notification information, the call determination unit 21c confirms whether the notification information acquired by the third acquisition unit 21a is the first notification information. If the notification information acquired by the third acquisition unit 21a is the first notification information, it detects whether there is notification information of another communication device 10. The call determination unit 21c confirms whether the other communication device 10 has output the second notification information. When it is determined that the second notification information has not been output, the call determination unit 21c creates the first call information based on the first notification information. In other words, when the notification information acquired by the third acquisition unit 21a is only the first notification information, the call determination unit 21c creates the first call information to be called due to the occurrence of a quasi-danger based on the first notification information. do. On the other hand, when the third acquisition unit 21a detects the first notification information and detects the second notification information output by the other communication device 10, the call determination unit 21c is based on the second notification information having a high degree of risk. Create the second call information to be called when a danger occurs.

Further, when the notification information acquired by the third acquisition unit 21a is not the first notification information and the third notification information, the call determination unit 21c confirms whether the notification information is the second notification information. When the notification information is the second notification information, the call determination unit 21c creates the second call information based on the second notification information.
When the notification information acquired by the third acquisition unit 21a does not correspond to any of the first notification information, the second notification information, and the third notification information, and when the fourth notification information is acquired, the fourth notification information is obtained. The management output unit 42b transmits the notification information to the server 50.

Hereinafter, the management machine 30 that responds to the call of the dispatch unit 20 will be described.
When neither the mapping mode nor the determination condition update mode is applicable, the management machine 30 detects whether the first call information, the second call information, and the third call information are output. The management machine 30 that has acquired the call information via the signal receiving unit 42a transmits the call information to the server 50. The management machine 30 requests the server 50 to transmit the positioning information of the communication device 10 that has output the notification information.

When the fourth acquisition unit 51a acquires the call information, the server 50 responds to the connection request of the management machine 30. The server 50 identifies the positioning information of the communication device 10 that outputs the notification information based on the call information acquired by the fourth acquisition unit 51a, the association information stored in the storage unit 52, and the field information. The server output unit 51b outputs the positioning information to the management machine 30. The signal receiving unit 42a receives the positioning information, and the management device 30 moves to the installation location of the communication device 10 that outputs the notification information based on the positioning information. In this way, the management device 30 is called to the installation location of at least one or more communication devices 10 among the plurality of communication devices 10 that output the notification information.

After moving to the installation location of the communication device 10, the management device 30 takes a predetermined action based on the call information. For example, the management machine 30 performs a warning action by the warning unit 48 and / and a monitoring action by the monitoring unit 47. Specifically, as shown in FIG. 2A, the warning unit 48 issues a warning sound to warn the intruder M2. When the monitoring unit 47 is a video camera that captures moving images, it captures moving images around the communication device 10 at the destination. The captured moving image data is associated with the identification information and stored in the management storage unit 46.

After moving to the predetermined standby location 3b, the management machine 30 transmits the information associated with the moving image data and the identification information to the server 50 via the management output unit 42b and the fourth acquisition unit 51a. The fourth acquisition unit 51a acquires the information. The registration unit 53 associates the information acquired by the fourth acquisition unit 51a with the field information and registers it in the storage unit 52. The information may be transmitted to the server 50 at the same time as the moving image is captured, or the information may be transmitted to the server 50 after the moving image is captured.

On the other hand, when the management machine 30 determines that the first call information, the second call information, and the third call information are not output, it confirms whether the fourth notification information is output. When the fourth notification information is received, the management machine 30 transmits the fourth notification information to the server 50.
If there is no field registration instruction and none of the first call information, the second call information, and the third call information is received, the server 50 confirms whether the fourth notification information is output from the management machine 30. When the server 50 acquires the fourth notification information, the registration unit 53 associates the fourth notification information with the field information and stores it in the storage unit 52.

Next, the determination condition update mode will be described. The determination condition update mode is a mode for updating the notification determination condition of the communication device 10. Specifically, the mobile terminal 60 is operated, and the update instruction unit 51b1 of the server 50 transmits an update instruction (update information) of the notification determination condition to the dispatch unit 20 or the management machine 30. The dispatch unit 20 or the management machine 30 that has received the update information from the server 50 transmits the update information to the communication device 10. The communication device 10 updates the notification determination condition based on the received update information. In the present embodiment, the values of the predetermined threshold values F1, F2, and F3 of the notification determination condition are changed.

When the setting button 106 of the home screen Q1 is selected, the screen display of the display unit 62 changes as shown in FIG. 20, and the setting screen Q4 as shown in FIG. 15 is displayed. When the condition change button 409 on the setting screen Q4 is selected, the monitoring change screen Q5 is displayed. In the present embodiment, "high" 501, "medium" 502, and "low" 503 of the monitoring change screen Q5 indicate the accuracy of the notification determination condition. If "high" 501 on the monitoring change screen Q5 is selected, the values of the predetermined thresholds F1, F2, and F3 are set smaller than the values of the predetermined thresholds F1, F2, and F3 of the "medium" 502. Further, when "low" 503 of the monitoring change screen Q5 is selected, the values of the predetermined threshold values F1, F2, and F3 are set to be larger than the values of the predetermined threshold values F1, F2, and F3 of the "medium" 502. That is, if "high" 501 is selected, the monitoring accuracy is set high, and if "low" 503 is selected, the monitoring accuracy is set low. If "Medium" 502 is selected, the monitoring accuracy is set between "High" 501 and "Low" 503.

When any of "high" 501, "medium" 502, and "low" 503 of the monitoring change screen Q5 is selected, the selected update information is transmitted from the mobile terminal 60 to the server 50. In the present embodiment, the notification determination condition is updated to a predetermined threshold value set in advance, but the threshold value can be freely changed, such as by directly inputting the threshold value. good. When the transmission of the update information is completed, the display unit 62 of the mobile terminal 60 shifts the screen display of the display unit 62 to the home screen Q1 as shown in FIG.

When the server 50 receives the update information from the mobile terminal 60, the update information is transmitted from the update instruction unit 51b1 of the server 50 to the management machine 30 and / or the dispatch unit 20. That is, the notification determination condition of the communication device 10 can be updated via either the management device 30 or the dispatch unit 20.
Hereinafter, a case where the notification determination condition is updated via the management machine 30 will be described.
The management machine 30 updates the notification determination condition of the communication device 10 in the same procedure as the mapping mode. For example, the management machine 30 that has received the update information from the update instruction unit of the server 50 moves to the field 3 where the communication device 10 is installed. The management machine 30 that has moved to the field 3 detects the identification information output from the communication device 10. The management machine 30 requests a connection to the communication device 10 that matches the identification information recorded in the management storage unit 46 or the storage unit 52. The communication device 10 requested to be connected connects with the management device 30. The management machine 30 designates the determination condition update mode to the communication device 10. The management device 30 and the communication device 10 disconnect the communication. Based on the threshold value stored in advance in the management storage unit 46, the position detection unit 41 acquires the positioning information at the point where the intensity of the identification information (radio wave) acquired by the first acquisition unit 43 is equal to or higher than the threshold value. The management machine 30 confirms whether it is in the mapping mode. In the case of not the mapping mode, that is, in the determination condition update mode, the management machine 30 outputs the update information.

The communication device 10 confirms whether the determination condition update mode is set. In the determination condition update mode, the communication device 10 receives the update information from the management device 30, and the determination update unit 13 updates the notification determination condition.

The communication device 10 updates the identification information in response to the request of the management device 30. The management device 30 and the communication device 10 disconnect the communication. The association unit 45 associates the positioning information of the communication device 10 for which the update of the notification determination condition has been completed with the updated identification information. The associated information is stored in the management storage unit 46. Alternatively, it is temporarily stored in the management storage unit 46 and transmitted to the server 50 via the management output unit 42b and the third acquisition unit 21a. The registration unit associates the information with the field information and registers the information in the storage unit 52. The management machine 30 may be configured to transmit update information to the dispatch unit 20 and update the notification determination conditions via the dispatch unit 20.

The notification creation unit 12c creates the second notification information (S27), and after shifting to the stealth mode setting process, the notification creation unit 12c determines whether or not the third condition of the notification determination conditions is met (S31). ).

When the second condition is met and the third condition is not met (S31, No), the output of the output unit 12b is initialized and the communication output is increased (S32). When the third condition is met (S31, Yes), the notification creation unit 12c sets (creates) the third notification information (S33). The communication device 10 confirms whether there is a connection request from the dispatch unit 20 (S34).
When there is no connection request from the dispatch unit 20, the output unit 12b of the communication device 10 reduces the communication output of the third notification information created by the notification creation unit 12c (S35).

If there is a connection request from the dispatch unit 20, the connection is made in response to the connection request (S36). If the dispatching unit 20 requests the receiving unit 12a to increase the output of the output unit 12b (S37, Yes), the communication device 10 raises the output of the output unit 12b and sends the third notification information from the output unit 12b.

Next, the connection process of the communication device 10 will be described with reference to FIG. 5C. When there is a connection request from the dispatch unit 20 or the management machine 30, the communication device 10 shifts to the connection process and determines whether or not it is in the mapping mode (S51). When it is determined that the mapping mode is set (S51, Yes), the output unit 12b of the communication device 10 temporarily reduces the output (S52). When the output unit 12b of the communication device 10 temporarily reduces the output, the management device 30 updates the identification information to the communication device 10 for which the registration of the field information is completed via the management output unit 42b and the reception unit 12a. Upon request, the communication device 10 updates the identification information in response to the request of the management device 30 (S53).

When it is determined that the mode is not the mapping mode (S53, No), the communication device 10 confirms whether the mode is the determination condition update mode (S54). In the determination condition update mode (S54, Yes), the receiving unit 12a receives the update information from the management machine 30 (S55), and the determination updating unit 13 updates the notification determination condition (S56). When the determination update unit 13 updates the notification determination condition, the management device 30 requests the communication device 10 for which the update of the notification determination condition has been completed to update the identification information, and the communication device 10 requests the management device 30. The identification information is updated accordingly (S53).

When it is determined that the determination condition update mode is not set (S54, No), the communication device 10 disconnects the communication and ends the connection process.
Next, a series of operations of the dispatch unit 20 will be described with reference to FIG. When the dispatch unit 20 is activated, the second communication unit 21 detects the notification information of the communication device 10 (S61). The call determination unit 21c determines whether the notification information is output (S62).

As a result, the management machine 30 is called.

When the call determination unit 21c determines that the notification information is not output from any of the output units 12b of the plurality of communication devices 10 (S62, No), the signal reception unit 42a is the server 50 or the mobile terminal 60. It is confirmed whether or not the activation information is received from (S64). When the signal receiving unit 42a receives the activation information from the server 50 or the mobile terminal 60 (S64, Yes), the dispatching unit 20 requests the communication device 10 set in the stealth mode to connect (S66). The communication device 10 requested to be connected connects to the dispatch unit 20 (S67). The second communication unit 21 of the dispatch unit 20 requests the communication device 10 set in the stealth mode to increase the output of the output unit 12b (request to output the third notification information) (S68). The second communication unit 21 disconnects the communication after the request for the increase in the output (S69). After disconnecting the communication with the communication device 10, the dispatch unit 20 detects the notification information of the communication device 10 again (S61).

When the dispatch unit 20 has not received the notification information and the activation information of the communication device 10 (S64, No), the dispatch unit 20 confirms whether the update information has been received from the server 50 or the management machine 30 (S70).
