Description

[Technical Field]

[0001] The present disclosure relates to an on-site operation panel for a fire extinguishing system, which is a disaster prevention system, that selects either an automatic water discharge mode or a manual water discharge mode to perform water discharge operations. [Background technology]

[0002] In buildings and other structures, there are on-site control panels that are installed in positions that allow direct observation of the target fire and allow fires to be extinguished manually. These on-site control panels are installed near the protected area.

[0003] This on-site control panel is installed in a sprinkler system or the like having a water-discharge head as fire extinguishing equipment. In this system, the water discharge mode can be selected between automatic and manual modes, and fire extinguishing work can be carried out by discharging water.

[0004] In sprinkler systems with this type of water-discharge head, fire extinguishing is controlled by a water-sprinkler control panel installed in the disaster prevention center. The water-sprinkler control panel is configured to allow selection between an automatic water-spray mode, which activates fire-extinguishing means such as sprinklers in conjunction with the activation of fire detection means installed in the protected area, and a manual water-spray mode, which allows remote operation of the fire-extinguishing means based on manual operation from an operation panel installed on the panel surface (see, for example, Patent Documents 1 and 2, and Non-Patent Document 1).

[0005] The on-site control panel installed in the protected area has the same configuration and functions as this sprinkler control panel. [Prior art documents] [Patent documents]

[0007] [Non-Patent Document 1] Nohmi Fire Prevention Co., Ltd. website, Nohmi Fire Detection and Suppression System NH100 Overview Manual for Water-Discharge Head Sprinkler Equipment (URL: https: / / www.nohmi.co.jp / shoka01 / 021 / rqim3400000018mw-att / TN20291R5.pdf) Summary of the Invention [Problem to be solved by the invention]

[0008] However, since the on-site control panel is installed in a location that is easily accessible to those who are not authorized to perform firefighting operations, such as general visitors to the facility, the on-site control panel is often housed in a cabinet with a door to prevent tampering.

[0009] Unlike fire hydrants, local control panels are not intended to be operated by ordinary outsiders, and are operated by an administrator. Therefore, a dedicated key owned by the administrator is required to operate the panel. In the following explanation, the person with authority over firefighting work will be referred to as the administrator.

[0010] In the unlikely event of a fire, if firefighting operations are to be carried out at the local control panel, the manager who detects the fire must take a special key stored at a disaster prevention center, etc., and go to the local control panel to operate it. However, the manager does not always start from the disaster prevention center, etc.

[0011] In addition, when a fire breaks out, many emergency response matters are concentrated on the manager, and for these reasons, the manager who happens to be present at the dedicated key storage location may not always be able to rush to the local control panel near the fire site.

[0012] For example, if a fire breaks out while a manager is patrolling a building and is near the fire site, he or she must manually operate the fire extinguishing equipment, such as opening and closing valves or setting water discharge zones, using the local control panel. This requires going to a storage location to retrieve a special key.

[0013] Therefore, operations that allow manual operation using a dedicated key stored in a specific location can sometimes result in inefficient operations, which can hinder a rapid response to fires.

[0014] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an on-site control panel that allows an administrator to manually perform fire-fighting operations at the desired timing using biometric authentication. [Means for solving the problem]

[0015] The local operation panel of the present disclosure is a local operation panel connected to a sprinkler control panel equipped with a control unit that selects either an automatic water-spraying mode in which the fire extinguishing means is activated in conjunction with the operation of the fire detection means, or a manual water-spraying mode in which the fire extinguishing means can be remotely operated based on manual operation from the panel and performs water-spraying operations, and further comprises a biometric authentication unit that reads the biometric authentication data of an administrator, and a memory unit in which an authorization table that associates the administrator with the biometric authentication data of the administrator and that grants operation authority in the manual water-spraying mode is pre-stored, and the control unit refers to the authorization table stored in the memory unit, and if the biometric authentication data of the administrator pre-stored in the authorization table contains data that matches the biometric authentication data read by the biometric authentication unit, enables manual operation from the panel. [Effects of the Invention]

[0016] According to the present disclosure, it is possible to obtain a local operation panel that allows a manager to manually perform fire extinguishing work at a desired timing using biometric authentication. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, preferred embodiments of the on-site control panel of the present disclosure will be described with reference to the drawings. The on-site control panel disclosed herein has a technical feature that, if it is confirmed through a biometric authentication function that the person in question is an administrator with specific authority, firefighting operations can be performed manually.

[0019] Embodiment 1 First, a fire extinguishing system to which a local operation panel according to the present disclosure is applied will be described. Fig. 1 is an explanatory diagram showing the overall configuration of a fire extinguishing system to which a local operation panel according to embodiment 1 of the present disclosure is applied. The fire prevention object in Fig. 1 is divided into three sections A, B, and C.

[0020] Each section is equipped with a fire detector 3 dedicated to the fire extinguishing system as a fire detection means, and a fixed head 4 as a fire extinguishing means. The units in a fire-protected structure where fires are extinguished, such as sections A, B, and C, are called protected sections.

[0021] The fixed head 4 is connected to a pipe. A remote control valve 5 is provided at the base end of the pipe, and a pressurized water supply device 6 consisting of a pump, a water tank, etc. is provided at the primary side of the pipe.

[0022] In addition, a local control panel 7 equipped with functions such as controlling the opening and closing of the remote control valve 5 is installed in a nearby location where people can directly monitor the fire prevention object in order to manually and remotely operate the fire extinguishing system.

[0023] The object of fire prevention is also equipped with fire detectors 1 and 2 for an automatic fire alarm system having a warning area that encompasses the protected area. The fire detectors 1 and 2 are connected via signal lines to a fire receiver 8 installed in a centralized control facility such as a disaster prevention center.

[0024] The fire detector 2 illustrated in FIG. 1 is a type of fire detector known as a photoelectric separation detector, which is divided into a light-receiving unit 2a and a light-emitting unit 2b, and monitors for fires between the light-receiving unit 2a and the light-emitting unit 2b.

[0025] Meanwhile, a fire detector 3 dedicated to the fire extinguishing system is connected via a signal line to a sprinkler control panel 10 (hereinafter referred to as a fire extinguishing system control panel) installed in a centralized management facility such as a disaster prevention center. Furthermore, this fire extinguishing system control panel 10 is connected to a fire receiver 8, a local operation panel 7, and a pump control panel 9 via signal lines.

[0026] The pump control panel 9 is installed in the fire pump room together with the pressurized water supply device 6. Note that Fig. 1 shows only one example of a fire extinguishing system, and the number of fire detectors and compartments will vary depending on the size of the fire prevention object. In addition to the fixed head 4, a movable head or the like may also be used as a fire extinguishing means.

[0027] The fire extinguishing system control panel 10 can receive fire signals from the fire receiver 8 and fire signals from the fire detector 3 dedicated to the fire extinguishing system. When a protected area in which the fire detector 3 dedicated to the fire extinguishing system has been activated is contained within a warning area in which the fire detector 1 or 2 for the automatic fire alarm system, which is the source of the fire signal sent via the fire receiver 8, has been activated, the fire extinguishing system control panel 10 executes control to automatically extinguish the fire in the protected area.

[0028] The mode in which the remote control valve is opened and water is automatically discharged when the AND condition is met between the fire detector 1 or 2 of the automatic fire alarm system and the fire detector 3 dedicated to the fire extinguishing system is met is called the automatic water discharge mode.

[0029] The fire extinguishing system control panel 10 and the local operation panel 7 are also equipped with a function that allows fires to be extinguished manually. This is called the manual water discharge mode. As mentioned above, the local operation panel 7 is installed in a location that is easily accessible to an unspecified number of people, including general visitors to the facility, who are not authorized to perform fire extinguishing work.

[0030] Therefore, in this disclosure, in order to increase the convenience of the local operation panel 7 for the manager, a function is added that allows the manager to manually perform fire extinguishing work at a desired timing without operating a dedicated key. Therefore, the functions of the local operation panel 7 included in the fire extinguishing system shown in Figure 1 will be described in detail.

[0031] Fig. 2 is a functional block diagram of the local operation panel 7 according to the first embodiment of the present disclosure. Fig. 2 shows a state in which the local operation panel 7 is connected to the fire extinguishing system control panel 10 so as to be consistent with the configuration shown in Fig. 1.

[0032] 2 is configured to include a biometric authentication unit 71, an operation input / output unit 72, an authorization table storage unit 73, and a control unit 74. The control unit 74 also has an input / output control function 74a and a mode switching function 74b.

[0033] Among these components, the main components related to new functions that can be realized by the local operation panel 7 according to the first embodiment are the biometric authentication unit 71, the authorization table storage unit 73, and the mode switching function 74b. Therefore, these functions will be mainly described in detail.

[0034] The operation input / output unit 72 and the input / output control function 74a are substantially the same as the prior art described in Patent Document 1 or Non-Patent Document 1, and a detailed description thereof will be omitted.

[0035] The biometric authentication unit 71 reads the biometric authentication data of the administrator. Examples of the biometric authentication data include face authentication data and fingerprint authentication data that can be used to identify the administrator.

[0036] An operation panel is provided at a position recessed from the front of the main body door of the local operation panel 7. An operation input / output unit 72 is provided on this operation panel, and serves as a human interface that displays output to the administrator and receives operation inputs from the administrator.

[0037] The operation of switching between the automatic water-discharge mode and the manual water-discharge mode is also performed manually using this operation input / output unit 72, and details will be described later with reference to FIGS.

[0038] The authorization table storage unit 73 corresponds to a storage unit that stores in advance an authorization table that associates administrators who are given the operation authority in the manual water discharge mode with the administrator's biometric authentication data.

[0039] 3 is an explanatory diagram showing a specific example of an authorization table stored in the authorization table storage unit 73 of the local operation panel 7 according to the first embodiment of the present disclosure. The authorization table stores in advance biometric authentication data for each administrator in association with each administrator to whom operation authority for the operation input / output unit 72 provided on the operation panel of the local operation panel 7 is given.

[0040] The input / output control function 74a in the control unit 74 communicates with the fire extinguishing system control panel 10, and thereby performs appropriate input / output control according to the situation via the operation input / output unit 72. In addition, the input / output control function 74a executes input / output control related to the operation input / output unit 72.

[0041] The mode switching function 74b in the control unit 74 utilizes the biometric authentication unit 71 and the authorization table storage unit to enable the administrator to operate the local operation panel 7 based on the biometric authentication result.

[0042] Furthermore, if necessary, it may be possible to control switching from the automatic water-discharge mode to the manual water-discharge mode, but normally the water-discharge mode switching control is performed by a mode switching signal from the fire extinguishing system control panel 10.

[0043] For example, when the AND condition of the above-mentioned sensors is satisfied on the fire extinguishing system control panel 10, a water discharge start timer (not shown) is activated to start a countdown to start water discharge. After the countdown ends, the remote control valve for the area is automatically opened, water discharge begins, and at the same time, the mode is automatically switched to manual mode.

[0044] Specifically, the mode switching function 74b refers to the authorization table stored in advance in the authorization table storage unit 73, and determines whether the biometric authentication data of the administrator stored in the authorization table includes data that matches the biometric authentication data read by the biometric authentication unit 71.

[0045] If data matching the biometric authentication data read by the biometric authentication unit 71 has been pre-registered in the authorization table, the mode switching function 74b enables the administrator to manually operate the operation input / output unit 72 without performing operations using a dedicated key.

[0046] When the fire extinguishing system control panel 10 is set to manual mode, the local operation panel 7 can be operated by operating the key switch with a dedicated key to switch the panel operation from disabled to enabled, but even if the dedicated key is not operated, if the administrator operating the panel is determined to be a person registered in the authorization table memory unit through biometric authentication, the local operation panel can be operated in the same way.

[0047] As described above, the on-site control panel 7 according to the present disclosure has a technical feature in that, by utilizing the biometric authentication function using the biometric authentication unit 71, if it is confirmed through biometric authentication that the person is an administrator with specific authority, fire extinguishing work can be performed by manual operation without operating a dedicated key. Therefore, this technical feature will be specifically described using Figures 4 and 5.

[0048] 4 is an explanatory diagram showing a biometric authentication unit 71 and an operation input / output unit 72 provided on the operation panel of the local operation panel 7 according to the first embodiment of the present disclosure. An acrylic door 7a is provided on the surface of the local operation panel 7 as a panel door to protect the operation panel. When the acrylic door 7a is in an open state, the administrator can operate the operation input / output unit 72.

[0049] A biometric authentication unit 71 is provided on the operation panel of the local operation panel 7 according to the first embodiment, together with an operation input / output unit 72. In Fig. 4, the portion of the operation input / output unit 72 that switches between the automatic water-discharge mode and the manual water-discharge mode is shown as a switching operation input / output unit 720. Fig. 4 also illustrates a case where the biometric authentication unit 71 is provided near the switching operation input / output unit 720.

[0050] 5 is an explanatory diagram showing an enlarged view of the biometric authentication unit 71 and the switching operation input / output unit 720 provided on the operation panel of the local operation panel 7 according to the first embodiment of the present disclosure. The switching operation input / output unit 720 is provided with a key switch 721 that enables manual operation of a remotely controlled object. The key switch 721 is designed so that a dedicated key 721a that is paired with the key switch 721 can be inserted therein.

[0051] In FIG. 5, when the keyhole of the key switch 721 is in the upper right direction, it means that the automatic water-discharge mode is selected, and when the keyhole of the key switch 721 is in the lower right direction, it means that the manual water-discharge mode is selected.

[0052] When the dedicated key 721a is not inserted in the key switch 721, the automatic water discharge mode is always selected, and the disable indicator light 722, which indicates that operation is disabled, is lit. In other words, while the disable indicator light 722 is lit, manual operation is prohibited, and the input / output control function 74a in the control unit 74 controls so that remote operation by the operation input / output unit 72 cannot be performed.

[0053] On the other hand, if it is desired to switch to manual water discharge mode, the administrator inserts the dedicated key 721a into the key switch 721 and turns it clockwise by approximately 90 degrees. As a result, the input / output control function 74a in the control unit 74 turns off the disabled indicator light 722 and turns on the enabled indicator light 723, thereby enabling remote operation by the operation input / output unit 72.

[0054] The key switch 721 is configured in such a way that the dedicated key 721a cannot be attached or detached when it is in an operating position where the remotely controlled object can be manually operated, and manual operation is not possible without the dedicated key 721a, so that manual operation of the remotely controlled object is reliably prohibited under normal circumstances.

[0055] In this way, it has been possible for an administrator to perform water spraying operations by selecting either an automatic water spraying mode, in which the fire extinguishing means is activated in conjunction with the operation of the fire detection means, or a manual water spraying mode, in which the fire extinguishing means can be remotely operated based on manual operation from the panel, by operating the dedicated key 721a.

[0056] In contrast, the local control panel 7 according to the first embodiment further includes a biometric authentication unit 71 in addition to the switching operation input / output unit 720 that conventional local control panels have. As a result, when switching from automatic water-discharge mode to manual water-discharge mode, the biometric authentication unit 71 can be used instead of a dedicated key 721a.

[0057] In other words, if the biometric authentication data is registered in advance in the authorization table and an administrator is granted specific authority, they can immediately perform firefighting operations manually based on the confirmation results of the biometric authentication function, without having to operate a dedicated key.

[0058] As a result, the inefficient operation that allows manual operation only with a dedicated key 721a stored in a specific location has been improved, and if a manager is given specific authority, when the fire detection means is activated and the timer for water discharge is counting, the manager can open the remote control valve 5 early in manual mode on-site and quickly perform initial fire extinguishing, etc., by manual operation.

[0059] Furthermore, by allowing manual operation based on biometric authentication only to administrators whose biometric authentication data has been registered in advance, manual operation by ordinary visitors to the facility can be prohibited. This makes it possible to prevent the local control panel installed near the protected area from being operated by anyone other than the administrator, thereby improving the convenience of operation by the administrator and ensuring security at the same time.

[0060] A supplementary explanation will be given regarding the authorization table. The authorization table shown in Fig. 3 associates the administrator name with the administrator's biometric authentication data, but the authorization table available in the local operation panel 7 according to the present disclosure is not limited to the configuration shown in Fig. 3.

[0061] 6 is an explanatory diagram showing a specific example of the second authorization table stored in the authorization table storage unit 73 of the local operation panel 7 according to the first embodiment of the present disclosure. The second authorization table is associated with each administrator to be given operation authority for the operation input / output unit 72 provided on the operation panel of the local operation panel 7, and stores in advance specific work contents for which authority is to be given to the administrator together with biometric authentication data for each administrator.

[0062] In FIG. 6, the following two tasks are shown as work contents. Task X: A task that can be performed as long as the need for water discharge can be confirmed. Work Y: Work that requires skill and proficiency

[0063] Specific examples of operation X include operations such as stopping the timer, starting water discharge, and stopping water discharge, and specific examples of operation Y include operations such as changing the water discharge section and changing the nozzle direction.

[0064] In addition, we will provide additional explanation about stopping the timer included in task X and changing the water discharge area included in task Y.

[0065] When a fire is detected, water is sprayed from the water discharge head, but the water is not sprayed "immediately"; a "timer" is started, and the water is sprayed after, for example, 100 seconds. During this 100 seconds, the manager will go to the site where the fire detector was activated and investigate whether it is a real fire.

[0066] If there is no real fire, the timer can be stopped by pressing a timer stop switch (not shown) on the local control panel 7, which prevents the open signal from being sent to the remote control valve 5 and prevents water from being discharged. Therefore, stopping the timer in this way is also included in the operable work X as long as the need for water discharge can be confirmed.

[0067] Furthermore, as shown in Figure 1, if multiple protected areas A to C are installed, a fire may occur that spans multiple protected areas. When a fire has broken out across multiple protected areas like this, the task of changing the area to a protected area that is not being sprayed with water in automatic water spray mode and spraying water in manual water spray mode corresponds to changing the water spray area, and is included in task Y as it can only be done by an experienced person.

[0068] The second authorization table shown in Figure 6 illustrates a case in which Nomi Ichiro, an expert, is given the authorization for both Task X and Task Y, while Nomi Jiro and Nomi Saburo, who are not experts, are given the authorization for Task X only.

[0069] The mode switching function 74b in the control unit 74 refers to the second authorization table stored in advance in the authorization table storage unit 73, and determines whether the biometric authentication data of the administrator stored in the second authorization table contains data that matches the biometric authentication data read by the biometric authentication unit 71.

[0070] If data matching the biometric authentication data read by the biometric authentication unit 71 is pre-registered in the second authorization table, the mode switching function 74b enables manual operation using the operation input / output unit 72 without performing operation using a dedicated key 721a.

[0071] At this time, the administrator who is now able to operate the system can also switch from automatic water-discharge mode to manual water-discharge mode, or conversely, switch from manual water-discharge mode to automatic water-discharge mode.

[0072] However, when manual operation is enabled, the mode switching function 74b controls the administrator who has performed biometric authentication so that only manual operations related to work content for which authority has been granted by the second authority granting table are possible.

[0073] As a result, by utilizing the biometric authentication function using the biometric authentication unit 71, if it is confirmed through biometric authentication that the administrator is an administrator with specific authority, it becomes possible to perform firefighting work manually, limited to the work content for which the administrator has been granted authority, without performing operations using the dedicated key 721a.

[0074] Task X and Task Y are merely examples. Other examples include granting authority over specific tasks only to those with special qualifications.

[0075] In other words, the manual operation tasks to which authority is to be granted can be restricted for each administrator who is pre-registered in the second authorization table, thereby preventing an inexperienced administrator from manually performing tasks that they are unfamiliar with.

[0076] A switch for returning to automatic water-discharge mode after the biometric authentication unit 71 has been used to switch to manual water-discharge mode can be provided on the operation panel adjacent to the biometric authentication unit 71. Alternatively, it is also possible to switch back to automatic water-discharge mode after a certain period of time has elapsed after the biometric authentication unit 71 has been used to switch to manual water-discharge mode.

[0077] Furthermore, after the manual water-discharge mode is set using the biometric authentication unit 71, it is possible to return to the automatic water-discharge mode by operating the dedicated key 721a.

[0078] As described above, according to the first embodiment, the on-site control panel installed near the protected area where general visitors to the facility pass through is configured to enable manual operation of firefighting operations without operating a dedicated key if it is confirmed through the biometric authentication function that the person in charge is an administrator with specific authority.

[0079] As a result, it is possible to improve the convenience for the administrator when performing manual operations, and to ensure security by prohibiting manual operations by unauthorized persons.

[0080] Furthermore, by utilizing the authorization table, it is possible to limit the work content to which authorization is granted for each authorized person who is permitted to perform manual operations. As a result, when manual operations are permitted based on biometric authentication, only manual operations related to work content appropriate for each administrator are permitted, and it is possible to prevent unfamiliar manual operations from being performed by mistake.
