Description

  The present invention is used in an existing network environment such as a government office, a school, a factory, a private company, etc., receives an external signal related to emergency information such as an emergency earthquake warning, a fire alarm, a security sensor information, etc. by a server, and The present invention relates to an emergency information network display system that instantly displays voice and images on the upper client terminal to convey the emergency information.

  In public offices, schools, factories, private companies, etc., in-house broadcasting has been used to transmit emergency information such as earthquakes and fires throughout the facility. Some factories have dedicated transmission devices for transmitting emergency information. Also, in these facilities and the like, in recent years, each employee's PC (Personal Computer) is often connected by a network such as an in-house LAN (Local Area Network) to enable mutual exchange of information. Using this, for example, when a fire occurs, a specific monitoring department judges the fire situation and sends instructions to the employee's PC by e-mail, etc. ing.

  Conventional systems for displaying and transmitting emergency conditions using a network include emergency cameras, computers with programmed video distribution and motion detection sensor functions, database servers, WEB servers, mail transmission servers, hub nodes, etc. A situation notification system is disclosed (see Patent Document 1). This is based on the above system constructed by a network including a server, compared to a simple system in which even the first level surveillance camera administrator knows the notification of emergencies such as illegal entry and obstacles. The notification is made even to the first level and the second level notifiers such as the residents of the whole town, area, and housing complex. As a result, many people recognize the occurrence of crimes and disasters, and the entire region can grasp accurate information in real time, so that the occurrence of secondary and tertiary emergencies can be suppressed.

  However, there are cases in which information is missed depending on the situation in the in-house broadcasting. In addition, when a dedicated transmission device or a network such as a LAN is newly introduced only for transmitting emergency information, the cost increases and cannot be easily introduced. In addition, when mail is transmitted via a network, information can be transmitted to each individual, but there is a problem that emergency information cannot be transmitted instantaneously because there is a time lag until the mail check, such as when another work is being performed on a PC.

  In addition, in a conventional emergency information notification means via a network or a system such as Patent Document 1, it is necessary to first analyze an emergency state by an administrator / monitorer or a server. There is a problem that it may not be possible to notify. In addition, the system of Patent Document 1 requires image data transfer via a network, and depending on the communication speed, there is a possibility that a large time lag occurs before information is transmitted.

  The present invention has been made to solve such problems, and can be easily used in facilities and the like using an existing network environment, such as emergency earthquake warning, fire alarm, security sensor information, etc. An object of the present invention is to provide an emergency information network display system capable of instantaneously displaying and transmitting emergency information on each person's PC in the facility.

  An emergency information network display system of the present invention comprises a server capable of receiving an input signal from at least one emergency information notification device, and a plurality of client terminals connected to the server via a network. Is a server that, when receiving an input signal from the emergency information notification device, transmits a display command signal corresponding to the signal source emergency information notification device to the plurality of client terminals, and the client terminal is a display device When the display command signal is received from the server, the terminal displays an image registered in the terminal corresponding to the display command signal on the display device. In particular, the display command signal is a packet signal having a maximum packet length of 9 characters.

  In the present invention, “network” refers to an electronic communication line capable of transmitting and receiving electronic signals such as the display command signal, and corresponds to a LAN, a WAN (Wide Area Network), or the like. In the present invention, unless otherwise specified, “register” means saving (storing) in a predetermined format in a storage device such as a hard disk drive (HDD) of a server or a client terminal. .

  In the client terminal, the operation of receiving the display command signal from the server and displaying the image corresponding to the signal is performed by a program executed on the terminal.

  In the client terminal, the image is displayed on the forefront of the display device even when a program other than the program is being executed.

  The server has a display device, and when receiving an input signal from the emergency information notification device, displays an image registered in the server corresponding to the emergency information notification device of the signal source on the display device. It is characterized by.

  The program includes means for registering the image in the client terminal and / or the server while confirming the content of the image for each frame listed on the screen displayed on the display device. To do.

  In the emergency information network display system of the present invention, when the server receives an input signal from an emergency information notification device such as an alarm device, the server transmits a display command signal corresponding to the signal source device to a plurality of client terminals. When the terminal receives this display command signal, it displays an image that conveys an emergency, so there is no intervention by an administrator on the way, analysis of emergency conditions on the server, transfer of image data, etc. -Signal transmission such as a packet signal between the server and the client terminal is instantaneously performed and the above display is performed. For this reason, emergency information generated in the facility can be instantly transmitted to each person using the client terminal with little lime lag from occurrence.

  Since the operation of receiving the display command signal from the server and displaying the image corresponding to the signal in the client terminal is performed by a program executed on the terminal, the server is added to the existing network. The emergency information network display system of the present invention can be introduced at low cost simply by installing the program on the existing terminal.

  In the client terminal, the image is displayed on the foreground of the display device even when a program other than the program is being executed, so that emergency information is generated without being overlooked even during other work. You can know from the time lag.

  An embodiment of the emergency information network display system of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram showing a configuration of an emergency information network display system. As shown in FIG. 1, the emergency information network display system includes a server 2 that can receive an input signal from the emergency information notification device 1, and a plurality of client terminals 4 connected to the server 2 via the network 3. Prepare. The emergency information notification device 1 is an alarm device, a fire alarm, a security sensor, an emergency earthquake warning unit, and the like, and is connected to the server 2 via an external input interface of the server 2. One or more emergency information notification devices 1 may be connected at the same time.

  The client terminal 4 includes a storage device that stores data such as an OS (Operating System), a display device (display) that displays an image that conveys emergency information, and the like. This display device may be externally connected to the terminal or may be integrated with the terminal (see FIG. 1). The storage device of the client terminal 4 stores, in addition to data such as the OS, an image that conveys an emergency, a sound corresponding to the image, a program that controls the display operation, and the like. As the client terminal 4, an existing PC used on an existing network can be used as it is. The above image / sound and program can be installed by installing them.

  The server 2 includes an external input interface for connecting to the emergency information notification device 1, a storage device for storing data such as an OS, and a display device 2a. As the storage device, an HDD, an SSD (Solid State Drive), or the like can be adopted. Since the server 2 operates continuously for a long time due to its nature, it is preferable to employ an SSD in order to reduce the failure rate. The storage device of the server 2 stores a program for controlling operations such as transmission of display command signals (described later (S1) to (S3)) in addition to data such as the OS. Further, when displaying an image that conveys emergency information similar to that of the client terminal 4 on the display device 2a of the server 2, a control program similar to that of the terminal 4 is also stored in the storage device.

  The network 3 that connects the server 2 and the client terminal 4 can be easily introduced at low cost, and therefore, it is preferable to use an existing LAN such as a government office, a school, a factory, or a private company. Note that a WAN or the like via the Internet network may be used as necessary. As will be described later, since the signal transmitted and received between the server 2 and the client terminal 4 is a short packet signal, the communication speed of the network 3 is slow (for example, 10 Mbps in the existing LAN). Can be used without stress.

  The connection between the server 2 and the client terminal 4 is performed according to the following procedure. (1) The server 2 waits in a reception state. (2) The client terminal 4 transmits a connection request to the IP address / port number of the server 2. (3) The client terminal 4 repeats connection request transmission every 30 seconds until it connects to the server 2. (4) The server 2 that has received the connection request stores the socket object with which the client terminal 4 is connected in the memory of the server 2, and the connection is completed. The above (1) to (4) are performed for all of the client terminals 4 on the network 3, and the socket object corresponding to each client terminal 4 is stored in the memory of the server 2.

  When the server 2 is powered off or the OS is terminated, the socket objects for all the client terminals 4 are released, so that all the client terminals 4 are not connected. In addition, when the client terminal 4 is powered off or the OS is terminated, the server releases only the socket object corresponding to the terminal, so that only the terminal is in an unconnected state, and the other terminals are maintained in a connected state.

  The flow from the occurrence of an emergency to the display on the client terminal will be described with reference to FIG. First, the emergency information notification device 1 such as a fire alarm or an earthquake early warning unit detects the occurrence of an emergency and sends a signal to the server 2 (S1). When the server 2 receives the input signal from the emergency information notification device 1, the server 2 determines the signal source device from the difference in the location (channel number) of the connected external input interface (S2). The server 2 stores the display command signal information corresponding to each connected emergency information notification device in the storage device. Therefore, after the signal reception / device determination, the server 2 corresponds to the signal source device. A display command signal is transmitted to each client terminal 4 via the network 3 (S3). For example, when the server 2 receives the fire alarm input signal, the server 2 transmits a packet signal indicating the channel number to which the fire alarm is connected to the client terminal 4.

  The display command signal transmitted from the server 2 to each client terminal 4 is a short packet signal (such as “IRQ XXX line feed”) having a maximum packet length of 9 characters. Further, the information of the client terminal 4 to which the display command signal is transmitted is based on the socket information of each client terminal 4 stored in the memory of the server 2.

  The operations of (S2) and (S3) are performed by the server 2 being automatically controlled by a program executed on the OS of the server. As the server OS and the language used for the program, known ones can be adopted as long as the operations of (S2) and (S3) can be realized.

  The display command signal from the server 2 can be transmitted to the client terminal 4 by manual control. For example, the display device 2a of the server 2 is used as a touch panel, a list of emergency displays registered in advance as shown in FIG. 3 is displayed, and the administrator or the like presses any button to display the registered emergency display. A display command signal is transmitted to the client terminal 4. Further, it is possible to access the server 2 from an arbitrary client terminal 4 and operate the client terminal to transmit a display command signal from the server 2 to each client terminal.

  When receiving the display command signal from the server 2, the client terminal 4 immediately displays an image corresponding to the display command signal on the display device (S4). An image corresponding to the display command signal is registered in advance in the terminal. For example, when a packet signal indicating a channel number connected to a fire alarm is received, an image indicating a fire occurrence registered in advance for the packet signal is displayed (see FIG. 4A). When a packet signal indicating the channel number to which the earthquake early warning unit is connected is received, an image indicating the occurrence of an earthquake registered in advance for the packet signal is displayed (see FIG. 4B). . As an image to be registered, an arbitrary image corresponding to the type of emergency information notification device or the like can be used. For example, an image as shown in FIG.

  Further, the client terminal 4 includes a sound reproduction device such as a speaker as necessary, and can reproduce the sound registered corresponding to the image simultaneously with the display of the image. By combining audio output, it is possible to prevent oversight of images.

  The operation (S4), audio reproduction, and the like are controlled by a program running on the OS of the client terminal 4. As the OS of the client terminal 4 and the language used for the program, known ones can be adopted as long as the operation of (S4) can be realized.

  The operation setting for the time for displaying the image can be arbitrarily set in the program. Further, as an operation setting, even if another program such as an editor other than this program is being executed, it can be set to be displayed on the forefront of the screen of the display device. By displaying the interrupt in the foreground, it is possible to prevent overlooking of the image. In order to be able to receive a display command signal whenever the terminal is activated, it is preferable that the program is resident at the same time as the OS activation.

  When displaying an image that conveys emergency information similar to that of the client terminal 4 on the display device 2a of the server 2, a program similar to the above program is executed on the OS of the server 2. In this case, when the server 2 receives an input signal from the emergency information notification device 1, the server 2 displays an image registered in the server corresponding to the emergency information notification device 1 of the signal transmission source on the display device 2a.

  In addition to the above-described operation control such as image display, a program having a function of performing the above-described image and sound registration itself will be described. This program has means for registering the image in the client terminal and / or the server while confirming the contents of the image for each frame listed on the screen displayed on the display device. An example of the registration screen is shown in FIG. In each of the enumerated frames in FIG. 6, a serial number is assigned corresponding to the display command signal, and can be registered by clicking each frame and inputting an image storage destination. The contents of the image to be registered can be confirmed on this list screen.

  Once the server 2 or any of the client terminals 4 performs image / sound registration and operation settings, the other terminals are installed with the program and configured with the registered files and the like. By duplicating the folder itself, the same operation can be performed.

  The operations (S1) to (S3) are performed by signal transmission between the emergency information notification device and the server and packet signal transmission between the server and the client terminal. Since there is no emergency analysis work, it can be executed instantly. The operation (S4) is immediately executed when the client terminal 4 receives the display command signal. For this reason, operations ((S1) to (S4)) from the occurrence of an emergency to the display on the client terminal are instantaneously performed, and emergency information generated in the facility is generated for each person using the client terminal. Can transmit less lime lag.

  The emergency information network display system of the present invention can be easily used by utilizing an existing network environment, and emergency information can be instantly displayed and transmitted to each person's PC in the facility. In a facility such as a private company, it can be suitably used as a security system against fire, earthquake, illegal intrusion, or other information transmission system.
