Description

[Technical Field]

[0001] The present disclosure relates to an inspection support system that enables inspection operations of a group of disaster prevention equipment using a fire receiver remotely via a mobile terminal. [Background technology]

[0002] Various types of fire detectors, fire alarms, etc. are used as disaster prevention equipment for detecting and reporting fires. Fire detectors monitor changes in conditions caused by an increase in ambient temperature or the generation of smoke, and output a fire signal when they detect the occurrence of a fire.

[0003] A specific example of a system equipped with such fire detectors is an automatic fire alarm system that is configured by placing fire detectors, fire receivers, transmitters, repeaters, sound devices, etc. in appropriate locations within a building to be protected from fire, thereby protecting people inside the building from fire (see, for example, non-patent document 1).

[0004] In an automatic fire alarm system, a fire detector detects heat, smoke, or flames and sends a fire signal to a fire receiver. The fire receiver that receives the fire signal issues an alarm and activates an audio device depending on the location of the fire, thereby notifying people in the building of the occurrence of a fire. The automatic fire alarm system disclosed in Non-Patent Document 1 can be configured as an appropriate system depending on the use and size of the building to be protected from fire.

[0005] The installation standards for such automatic fire alarm systems are determined according to the purpose and scale of the fire protection target. Furthermore, automatic fire alarm systems are required to undergo legal inspections when newly installed and during regular inspections.

[0006] Inspection of automatic fire alarm systems has traditionally been carried out by at least two inspectors. Specifically, one inspector operates a fire receiver installed within the facility to create a simulated fire at the fire detector being inspected. The other inspector waits near the fire detector to check whether it properly activates the alarm.

[0007] Each inspection worker will repeatedly carry out the above-mentioned work while communicating with each other for all the fire detectors that are to be inspected.

[0008] It is enough if the two people required for the inspection work can be secured without any problems. However, as the construction of a new property nears the end, situations arise where many inspections must be carried out within a limited time. Furthermore, in recent years, overtime regulations have become stricter, making it difficult to secure sufficient personnel. Therefore, there is a strong demand for more efficient inspection work.

[0009] Therefore, in order to improve the efficiency of inspection work, a system has been proposed that allows a fire receiver to be remotely operated using a mobile terminal, enabling inspection work to be carried out by one person (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0011] [Non-Patent Document 1] Nohmi Bosai Co., Ltd. website, Automatic Fire Alarm System (URL: https: / / www.nohmi.co.jp / product / materiel / fid.html) Summary of the Invention [Problem to be solved by the invention]

[0012] In Patent Document 1, in order to solve the problem that being able to operate the fire receiver remotely may result in the wrong operation being performed to restore the system in the event of a fire, remote operation is only possible in the vicinity of the fire receiver.

[0013] However, in Patent Document 1, if someone is near the fire alarm receiver, they can remotely control it using a mobile terminal at any time. Therefore, there is a problem that the receiver can be remotely controlled even after the installation is completed and the automatic fire alarm system has started to operate.

[0014] Furthermore, in Patent Document 1, the fire alarm cannot be operated using a mobile terminal unless the person is close to the fire alarm, so the area in which remote operation is possible is quite limited.

[0015] Furthermore, if one worker wants to remotely operate multiple fire alarms, he or she must go near each of the fire alarms. Therefore, Patent Document 1 has strict limitations on remote operation and is inconvenient in practical terms, so it is desirable to further improve the convenience of remote operation.

[0016] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an inspection support system that can improve work efficiency and convenience through remote operation when inspecting automatic fire alarm equipment, and can prevent disaster prevention equipment from malfunctioning through remote operation. [Means for solving the problem]

[0017] The inspection support system according to the present disclosure is an inspection support system comprising a plurality of automatic fire alarm systems, a server, and a mobile terminal, each of which is configured to have a disaster prevention equipment group including a plurality of fire detectors and a fire receiver that manages the disaster prevention equipment group, the server is communicatively connected to each of the fire receivers included in the plurality of automatic fire alarm systems via a communication network, and manages, for each fire receiver, whether it is a fire receiver to be remotely controlled using the mobile terminal, the mobile terminal is communicatively connected to each of the fire receivers and the server via the communication network, and installs dedicated application software that enables the disaster prevention equipment group connected to a fire receiver with which a connection state has been established via the communication network to be remotely operated in place of inspection operations using the fire receiver, or makes the application software available via the communication network, and it is possible to establish a connection state via the communication network only for fire receivers among the fire receivers that are managed by the server as fire receivers to be remotely controlled, and the disaster prevention equipment group connected to a fire receiver with which a connection state has been established can be remotely controlled using the dedicated application software. [Effects of the Invention]

[0018] According to the present disclosure, an inspection support system can be obtained that can improve work efficiency and convenience through remote operation when inspecting automatic fire alarm equipment, and can prevent disaster prevention equipment from malfunctioning due to remote operation.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, preferred embodiments of the inspection support system of the present disclosure will be described with reference to the drawings. The inspection support system of the present disclosure has the technical feature of centrally managing multiple automatic fire alarm systems that can be remotely controlled using a mobile terminal on a server, and enabling remote control of one or more automatic fire alarm systems that can be remotely controlled by running dedicated application software on the mobile terminal.

[0021] Embodiment 1 First, the automatic fire alarm system that is the target of remote control will be described. 1 is a diagram illustrating the overall configuration of an automatic fire alarm system that is a target for remote operation by an inspection support system according to embodiment 1 of the present disclosure. A fire receiver 110 included in the automatic fire alarm system 100 shown in FIG. 1 is connected to an addressable transmitter 120, fire detectors 131 and 132, a detector repeater 140, and a smoke prevention and exhaust control repeater 150 via a signal line SG.

[0022] A plurality of fire detectors are connected to the detector repeater 140. In Fig. 1, four fire detectors 141 to 144 are shown as an example. In addition, a fire door 151, a smoke exhaust machine 152, a shutter 153, and a hanging wall 154 are connected to the smoke prevention and exhaust control repeater 150.

[0023] Here, the fire detectors 131, 132 and the fire detectors 141 to 144 correspond to a plurality of fire detectors that detect the occurrence of a fire in each of the preset fire monitoring areas. A plurality of fire detectors constitutes a detector group.

[0024] Additionally, the fire door 151, the smoke exhauster 152, the shutter 153, and the hanging wall 154 correspond to a plurality of terminal equipment that operate in conjunction with the detection results of the plurality of fire detectors and function to prevent the spread of fire, smoke, etc. A terminal equipment group is made up of a plurality of terminal equipment.

[0025] Address information for identifying each individual fire detector is assigned in advance to each of the multiple fire detectors. Each of the multiple fire detectors can transmit fire-related information including the address information assigned to it to the fire receiver 110. Meanwhile, the fire receiver 110 can transmit necessary information to a desired fire detector by adding address information to the information.

[0026] Furthermore, each of the multiple terminal devices is assigned address information in advance to identify the individual terminal device. Therefore, the fire alarm receiver 110 can transmit a command to operate the desired terminal device by adding the address information and transmitting the information.

[0027] With this configuration, the fire receiver 110 collects fire-related information from a plurality of fire detectors installed in various predetermined fire monitoring areas and the addressable transmitter 120. Then, the fire receiver 110 can issue a fire alarm and activate a group of terminal equipment based on the collected fire-related information.

[0028] It is to be noted that each terminal equipment included in the terminal equipment group is specified in advance as to which fire detector detection result it should operate in conjunction with. For example, by setting in advance the correspondence between the interlocking operations of multiple fire detectors and multiple terminal equipment as an interlocking table, the fire receiver 110 can identify the appropriate terminal equipment from the interlocking table based on the detection results of each of the multiple fire detectors and perform interlocking operations.

[0029] Also, although not shown in the figure, the fire receiver 110 can output an alarm signal based on the collected fire-related information, activate fire extinguishing equipment to begin fire extinguishing operations, issue a fire alarm or provide evacuation guidance using an emergency broadcast device, output an audio signal using a local sound device, and transmit fire-related information to a higher-level device via a network.

[0030] Such automatic fire alarm systems 100 are required to undergo statutory inspections when newly installed and during periodic inspections. To perform the statutory inspections, an inspector operates the fire receiver 110 to check the operation of the fire prevention devices that are the subject of the inspection.

[0031] Here, the fire prevention equipment group includes the detector group and terminal equipment group shown in Figure 1, as well as fire extinguishing equipment, emergency broadcast equipment, local sound equipment, etc., which are not shown, and includes all equipment that can be operated from the fire receiver 110 in inspection mode.

[0032] Next, we will explain in detail the inspection support system of the present disclosure, which enables remote operation of a group of fire prevention equipment using a mobile terminal during construction when installing a new automatic fire alarm system 100 such as that shown in Figure 1 in a fire prevention facility.

[0033] 2 is an overall configuration diagram of an inspection support system according to the first embodiment of the present disclosure. The inspection support system according to the first embodiment is configured to include a plurality of automatic fire alarm systems 100(1) to 100(N), a server 200, and a mobile terminal 300.

[0034] Here, each of the multiple automatic fire alarm systems 100(1) to 100(N) corresponds to the automatic fire alarm system 100 shown in Fig. 1, but the specific configuration of the fire prevention equipment group differs depending on the building to be protected from fire. Note that Fig. 2 illustrates an example in which the automatic fire alarm system 100(1) and the automatic fire alarm system 100(N) include fire sensors 131 and 132.

[0035] In other words, each of the multiple automatic fire alarm systems 100(1) to 100(N) is configured to have a disaster prevention equipment group including multiple fire detectors and a fire receiver 110 that manages the disaster prevention equipment group, and the specific configuration of the disaster prevention equipment group varies depending on the building that is the target of fire protection. In the following explanation, the building or the like that is the target of fire protection will be referred to as the fire protection object.

[0036] The server 200 is communicably connected to each of the fire receivers 110 included in the multiple automatic fire alarm systems 100(1) to 100(N) via a communication network 400. The server 200 manages whether each of the fire receivers 110 is a fire receiver 110 that can be remotely controlled using a mobile terminal 300.

[0037] Specifically, data relating to each of the fire receivers 110 installed in all fire prevention objects is registered in the server 200. Furthermore, in a specific example in the first embodiment, it is assumed that only the fire receivers 110 installed in fire prevention objects under new construction (construction) are registered in the server 200 as remotely operable fire receivers 110.

[0038] Renovation work on an existing fire prevention object is generally carried out while the object is in use. If remote control is performed in this state, there is a risk that a shutter or the like may be inadvertently operated, resulting in an accident involving the user. To prevent such an accident, in the first embodiment, the server 200 manages the fire receiver 110 installed in the fire prevention object under renovation as one that cannot be remotely operated.

[0039] On the other hand, during new construction work, there is no problem if all functions of the fire receiver 110 can be remotely controlled. Therefore, in the first embodiment, as described above, only the fire receivers 110 installed in fire prevention objects under new construction work are registered in the server 200 as fire receivers 110 that can be remotely controlled.

[0040] In addition, a person who has the authority to change the management information of the server 200 can, for example, change the settings of a fire receiver 110 installed in a specific fire prevention object undergoing renovation work so that it can be remotely operated.

[0041] In addition, a person with the authority to change the management information of the server 200 can change the settings of a fire receiver 110 installed in a fire prevention object under construction, for example, so that it cannot be remotely operated during periods when the general public is entering the fire prevention object for preview events, etc.

[0042] Furthermore, if it is desired to limit the remotely operable items, it is also conceivable to associate each fire receiver 110 with the operation items that can be remotely controlled and manage them as management information in the server 200.

[0043] In other words, according to the inspection support system of this embodiment 1, the fire receivers 110 that can be remotely controlled and the operation items that enable remote control of each fire receiver 110 can be centrally managed by the server 200 as management information, and the settings can be changed as necessary.

[0044] The mobile terminal 300 is communicably connected to each of the fire receivers 110 and the server 200 via the communication network 400. Furthermore, in the specific example of the first embodiment, the mobile terminal 300 has the following functions.

[0045] <Function 1> The mobile terminal 300 has the function of using dedicated application software that enables remote operation of a group of disaster prevention equipment connected to the fire receiver 110, which has established a connection via the communication network 400, instead of inspection operations using the fire receiver 110.

[0046] The dedicated application software may be of either the type that uses application software that runs on a web browser using the mobile terminal 300 (a so-called "WEB application"), or the type that runs directly on the mobile terminal 300 by being installed on the mobile terminal 300 in each terminal environment (native environment) (a so-called "native application").

[0047] That is, the dedicated application software according to the present disclosure may be of any type as long as it can be used by a remote operator using the mobile terminal 300. In the following, a specific example will be described in which a "native app" type is adopted as the dedicated application software and the dedicated software can be installed on the mobile terminal 300.

[0048] <Function 2> The mobile terminal 300 can establish a connection state via the communication network 400 only with the fire receivers 110 that are managed by the server 200 as fire receivers to be remotely controlled, among the fire receivers 110 included in the multiple automatic fire alarm systems 100(1) to 100(N).

[0049] <Function 3> By using dedicated application software, the mobile terminal 300 can remotely control the disaster prevention equipment connected to the fire receiver 110 with which a connection has been established, instead of performing inspection operations using the fire receiver 110.

[0050] Here, in the following explanation, the state in which communication is established between the fire receiver 110 to be remotely controlled and the mobile terminal 300 using function 2, and the state in which the fire receiver 110 to be remotely controlled can be remotely controlled from the mobile terminal 300 using function 3, will be referred to as ``synchronization'' or ``synchronized state.''

[0051] The fire receiver 110, server 200, and mobile terminal 300 work together, and the fire receiver 110 and mobile terminal 300 to be remotely controlled are synchronized, making it possible to remotely control the mobile terminal 300 with dedicated application software installed.

[0052] A series of processes relating to remote control executed in cooperation with the fire receiver 110, the server 200, and the mobile terminal 300 in the inspection support system according to the first embodiment will now be described with reference to FIGS.

[0053] Fig. 3 is a flow diagram showing a first series of processes related to remote operation executed in the inspection support system according to the first embodiment of the present disclosure, and Fig. 4 is a flow diagram showing a second series of processes related to remote operation executed in the inspection support system according to the first embodiment of the present disclosure.

[0054] 3 and 4 show a representative example in which the multiple automatic fire alarm systems 100 are composed of two systems, a first automatic fire alarm system 100(1) and a second automatic fire alarm system 100(2), and the first fire receiver 110(1) in the first automatic fire alarm system 100(1) and the second fire receiver 110(2) in the second automatic fire alarm system 100(1) are linked to the server 200 and the mobile terminal 300.

[0055] In addition, the first series of processes shown in Figure 3 and the second series of processes shown in Figure 4 differ in the procedures for achieving synchronization between the mobile terminal 300 and the fire receiver 110 to be remotely controlled, but the remote control procedures after achieving synchronization are the same.

[0056] In the description using FIGS. 3 and 4, it is assumed that dedicated application software has already been installed on the mobile terminal 300.

[0057] In addition, the first automatic fire alarm system 100(1) including the first fire receiver 110(1) and the second automatic fire alarm system 100(2) including the second fire receiver 110(2) are in a newly installed state, and both the first fire receiver 110(1) and the second fire receiver 110(2) are managed by the server 200 as fire receivers 110 that can be remotely controlled using the mobile terminal 300.

[0058] First, a description will be given of the first series of processes shown in Fig. 3. In step S301, the mobile terminal 300 starts dedicated application software and transmits to the server 200 a synchronization request regarding the first fire receiver 110(1) and the second fire receiver 110(2) that are to be remotely controlled.

[0059] Next, in step S302, the server 200 that has received the synchronization request refers to management information that manages which fire receivers 110 are remotely controlled using the mobile terminal 300, and determines whether or not the first fire receiver 110(1) and the second fire receiver 110(2) can be synchronized.

[0060] 3, the first fire receiver 110(1) and the second fire receiver 110(2) are both managed by management information as fire receivers 110 to be remotely controlled using the mobile terminal 300. Therefore, the server 200 generates synchronization permission information for the first fire receiver 110(1) and the second fire receiver 110(2) that permits synchronization, and returns the synchronization permission information to the mobile terminal 300.

[0061] Next, in step S303, the mobile terminal 300 receives the synchronization possibility information as a reply to the synchronization request, and can establish a connection state via the communication network 400 with each of the first fire receiver 110(1) and the second fire receiver 110(2) for which synchronization permission has been obtained.

[0062] In addition, a mobile terminal 300 running dedicated application software is not able to establish a connection with a fire receiver 110 that has been denied synchronization due to failure to obtain synchronization permission from the server 200.

[0063] In this way, through the series of processes from step S301 to step S303, the mobile terminal 300 can establish a connection state with each of the first fire receiver 110(1) and the second fire receiver 110(2) that have received synchronization permission from the server 200, and achieve synchronization.

[0064] In addition, while synchronization is established, the first fire receiver 110(1) and the second fire receiver 110(1) can notify the operator of each fire receiver 110 that remote operation is possible by displaying an identification that the receiver is "remotely synchronized."

[0065] Next, in step S304, the mobile terminal 300 executes dedicated application software to remotely operate desired disaster prevention equipment included in the group of disaster prevention equipment that can be operated from the first fire receiver 110(1) with which synchronization has been established, instead of performing inspection operations from the first fire receiver 110(1).

[0066] Similarly, in step S304, the mobile terminal 300 executes dedicated application software to perform remote control of desired disaster prevention equipment included in the group of disaster prevention equipment that can be operated from the second fire receiver 110(2) with which synchronization has been established, instead of inspection operations from the second fire receiver 110(2).

[0067] In step S305, the first fire receiver 110(1) performs remote operation based on the remote operation command for the first fire receiver 110(1) received from the synchronized mobile terminal 300.

[0068] Similarly, in step S306, the second fire receiver 110(2) performs remote operation based on the remote operation command for the second fire receiver 110(2) received from the synchronized mobile terminal 300.

[0069] In step S307, if the state in which synchronization is established between the first fire receiver 110(1) and the mobile terminal 300 has elapsed for a predetermined time corresponding to a preset remote control allowable time, the first fire receiver 110(1) can forcibly cancel synchronization, thereby making it impossible to remotely control the first fire receiver 110(1) from the mobile terminal 300 after the predetermined time has elapsed.

[0070] Alternatively, in step S307, even if the operator of the first fire receiver 110(1) operates a forced release switch to disable remote operation, the first fire receiver 110(1) can forcibly release synchronization, thereby disabling remote operation from the mobile terminal 300 even if it is within a specified time.

[0071] Similarly, in step S308, if the second fire receiver 110(2) is in synchronization with the mobile terminal 300 for a predetermined time period corresponding to a preset remote control allowable time period, the second fire receiver 110(2) can forcibly cancel synchronization, thereby disabling remote control from the mobile terminal 300 even within the predetermined time period.

[0072] Alternatively, in step S308, even if the operator of the second fire receiver 110(2) operates a forced release switch to disable remote operation, the second fire receiver 110(2) can forcibly release synchronization, thereby disabling remote operation from the mobile terminal 300 even if it is within a specified time.

[0073] The forced release switch may be a hardware switch or a software switch operated by a touch panel. In steps S307 and S308, a synchronization release command is output from fire control device 110 to mobile terminal 300 to notify that the fire control device 110 has released synchronization and is no longer accepting remote control commands.

[0074] Furthermore, when the mobile terminal 300 receives a synchronization release command and is released from synchronization, the mobile terminal 300 performs the operations of steps S301 to S303 again to establish synchronization again.

[0075] Next, a description will be given of the second series of processes shown in Fig. 4. In the first series of processes shown in Fig. 3, a series of processes from step S301 to step S303 was executed as an operation for establishing synchronization.

[0076] In contrast, the second series of processes shown in FIG. 4 differs in that a series of processes from step S401 to step S405 is executed as an operation for establishing synchronization, instead of step S301 to step S303.

[0077] Note that the remote control after synchronization is established is the same as steps S304 to S308 in Figures 3 and 4. Therefore, the following description will focus on steps S401 to S405, which are the differences.

[0078] In step S401, the server 200 refers to management information that manages which fire receivers 110 are remotely controlled using the mobile terminal 300, and determines whether the first fire receiver 110(1) and the second fire receiver 110(2) can be synchronized.

[0079] 4, the first fire receiver 110(1) and the second fire receiver 110(2) are both managed by management information as fire receivers 110 to be remotely controlled using the mobile terminal 300. Therefore, the server 200 notifies each of the first fire receiver 110(1) and the second fire receiver 110(2) in advance that they are both managed as being in a synchronization-permitted state.

[0080] Next, in step S402, the mobile terminal 300 starts dedicated application software and transmits a synchronization request to the first fire receiver 110(1) and the second fire receiver 110(2) that are to be remotely controlled.

[0081] Next, in step S403, the first fire receiver 110(1) that has received the synchronization request from the mobile terminal 300 can return synchronization permission information indicating that synchronization is permitted to the mobile terminal 300, since synchronization permission has been obtained from the server 200 in the previous step S401.

[0082] In addition, if the first fire receiver 110(1) does not receive synchronization permission from the server 200, it will return synchronization permission information indicating that synchronization is denied to the mobile terminal 300 that sent the synchronization request.

[0083] Similarly, in step S404, the second fire receiver 110(2) that receives the synchronization request from the mobile terminal 300 can return synchronization permission information indicating that synchronization is permitted to the mobile terminal 300, since synchronization permission has been obtained from the server 200 in the previous step S401.

[0084] In addition, if the second fire receiver 110(2) does not receive synchronization permission from the server 200, it will return synchronization permission information indicating that synchronization is denied to the mobile terminal 300 that sent the synchronization request.

[0085] Next, in step S405, the mobile terminal 300 receives the synchronization possibility information as a reply to the synchronization request, and can establish a connection via the communication network 400 with each of the first fire receiver 110(1) and the second fire receiver 110(2) for which synchronization permission has been obtained.

[0086] It should be noted that the mobile terminal 300 running the dedicated application software is not able to establish a connection with the fire control panel 110 for which synchronization permission has not been obtained and synchronization has been refused.

[0087] In this way, through the series of processes from step S401 to step S405, the mobile terminal 300 can establish a connection state with each of the first fire receiver 110(1) and the second fire receiver 110(2), which are managed by the server 200 as being in a synchronization-permitted state, and achieve synchronization.

[0088] In addition, while synchronization is established, the first fire receiver 110(1) and the second fire receiver 110(1) can notify the operator of each fire receiver 110 that remote operation is possible by displaying an identification that the receiver is "remotely synchronized."

[0089] Regarding the remote control after synchronization is established in steps S401 to S405, the series of processes in steps S304 to S308 described above with reference to FIG. 3 are executed, and detailed description thereof will be omitted.

[0090] The features of the inspection support system according to the first embodiment, which can execute the first series of processes shown in steps S301 to S308, or the second series of processes shown in steps S401 to S405 and steps S304 to S308, can be summarized as follows:

[0091] Feature 1: Remote operation can be performed only by the mobile terminal 300 dedicated to construction. As a result, operators who can perform remote operation using the mobile terminal 300 can be easily limited.

[0092] Feature 2: Dedicated application software can be used to perform remote control processing and synchronization establishment processing. As a result, the operator can more easily execute the series of processes.

[0093] By utilizing dedicated application software, all inspection operations can be performed using the fire control panel. However, if you want to limit the items that can be operated remotely, you can set restrictions using the server 200, each fire control panel 110, or dedicated application software.

[0094] Feature 3: The server 200 can manage the status of multiple fire receivers so that remote control is limited to fire receivers installed in fire prevention buildings under construction. As a result, it is possible to prevent situations in which remote control is inadvertently performed during periodic inspections, and all fire receivers managed by the server 200 can be remotely controlled.

[0095] Feature 4: In a fire receiver that is in a synchronized state that allows remote operation, it is possible to clearly display "remote synchronization in progress" on the display, etc. As a result, the operator of the fire receiver 110 can know that remote operation is being performed, and can also recognize a situation in which synchronization should be forcibly interrupted, if necessary.

[0096] Feature 5: Even after synchronization is established, the synchronized state can be forcibly released after a predetermined time has elapsed or by operating a switch. As a result, it is possible to prevent the remote control from being left in a state where it can be operated remotely, and to prevent it from being operated carelessly or more than necessary.

[0097] Feature 6: In addition to forcibly canceling synchronization, synchronization can also be canceled if the radio wave signal between the mobile terminal and the fire alarm receiver is poor and the signal is interrupted. As a result, remote control can be performed only when the radio wave signal is good, ensuring stable operation performance.

[0098] Feature 7: When resynchronizing the mobile terminal 300 that has been desynchronized by the above-described feature 5 or feature 6, the mobile terminal 300 can be configured to re-establish a synchronized state in cooperation with the server 200 and the fire control panel 110. As a result, the synchronized state can be managed in strict procedures under the management of the server 200.

[0099] As described above, according to the first embodiment, an inspection support system can be constructed that can realize Features 1 to 7. As a result, there is no need to place restrictions on the locations where remote operation is possible, and it is possible to improve work efficiency and convenience by remotely operating a plurality of fire alarm receivers under the management of a server, and to prevent disaster prevention equipment from malfunctioning due to remote operation.

[0100] In the first embodiment, the mobile terminal 300 and the fire receiver 110 communicate directly with each other. However, the communication between the mobile terminal 300 and the fire receiver 110 may be performed via the server 200. In this case, the mobile terminal 300 and the server 200 are synchronized, and the fire receiver 110 and the server 200 are synchronized with each other. The server 200 relays remote control of a desired disaster prevention device from the mobile terminal 300, allowing the remote control to be performed in place of an inspection operation from the fire receiver 110.

[0101] In this case as well, the server 200 is involved, but the mobile terminal 300 and the fire control panel 110 are synchronized. [Explanation of symbols]
