Description

  The present invention relates to a notification communication device and a notification communication system for notifying an event that has occurred in a remote place during a power failure.

  In various factories, regardless of the production scale, power supply stoppage (power outage) is not allowed. For example, production of electrical equipment that requires temperature control that strictly maintains the cold temperature or high temperature over a certain period of time, such as forming an insulating material with thermosetting resin or coating the outer box In the unlikely event of a power outage to equipment, all materials, parts, and work man-hours are all wasted, and post-processing costs for defective products increase, resulting in significant damage. Therefore, when a power failure occurs, it is necessary to provide a power failure recovery allowance promptly.

  Once a power failure occurs, restoration work cannot be performed unless it is a chief electrical engineer or a person in charge of electrical equipment maintenance. Even if the emergency contact network has a good telephone contact system, it may take several hours depending on the time of day. It is necessary to report a power outage to a technician or a person in charge of electrical equipment maintenance. To do so, the power outage must be detected quickly.

  For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-110114, title of the invention “monitoring device”) is disclosed as a device for reporting a power failure when such a power failure occurs. In the invention of Patent Document 1, an excellent device or system is constructed such as a device that provides alarm and notification means from detection of a power failure, and further arranges a device capable of finely controlling the load, a private power generation switching device, or a specialized maintenance staff. I can do it.

  Further, as another device for reporting a power failure when a power failure occurs, for example, Patent Document 2 (Japanese Patent Laid-Open No. 2002-140779, name of invention “remote integrated monitoring system”) is disclosed. In the invention of Patent Document 2, there are many monitoring items such as disaster prevention and crime prevention with respect to a completely unmanned facility, and it is a system for remotely reporting.

JP 2004-110114 A (paragraph numbers [0010], [0011], FIG. 1) JP 2002-140779 A (paragraph numbers [0009] to [0030], FIG. 1)

However, the monitoring device of Patent Document 1 and the remote integrated monitoring system of Patent Document 2 are large-scale systems that are limited to large-scale offices and important plants, and similarly, a large amount of cost is required for installation work and operation maintenance. There is a problem that it is generally difficult to spread.
Commercial power sources from electric power companies do not have frequent power outages, and business owners hesitated to install expensive equipment and systems to deal with power outages that rarely occur. Furthermore, there was a situation that it was preferable to be able to cope with various events such as a fire as well as a power failure.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide an informing communication device that informs of an event occurring in a remote place even at the time of a power failure with an inexpensive configuration. And it is providing the communication system for alerting | reporting.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a notification communication device and a notification communication system of the best mode for carrying out the present invention will be described collectively. FIG. 1 is a configuration diagram of a notification communication apparatus according to this embodiment.
The notification communication device 100 includes an input driver 10, an output driver 20, a wireless communication device 30, a wired communication device 40, a control calculation unit 50, and a UPS power supply device 60.

  The input driver 10 is connected to the control calculation unit 50 and an event detection device (not shown), receives a detection signal output from an external event detection device, and outputs the detection signal to the control calculation unit 50. This detection signal detects various events, and is, for example, an analog signal. The input driver 10 converts an analog detection signal into a digital detection signal and outputs the digital detection signal to the control calculation unit 50. Note that detection signals may be input from a plurality of event detection devices, or a large number of detection signals may be input from a single event detection device. Note that when an external event detection device is connected to the input driver 10, power from the UPS power supply device 60 may be supplied from the input driver 10 to the event detection device via a connection line. Further, the power may be supplied by connecting the power line of the UPS power supply 60 directly to the event detection apparatus. In the case where the event detection device is a sensor that does not require a power source, power is not supplied.

  The output driver 20 is connected to the control calculation unit 50 and a notification device (not shown), receives the notification signal output from the control calculation unit 50, and outputs the notification signal as a notification signal suitable for an external notification device. This notification signal is a signal for driving the notification device to perform voice notification and display notification, and is, for example, an analog signal. The output driver 20 converts the digital signal notification signal from the control calculation unit 50 into an analog notification signal and outputs the analog notification signal. In addition, a notification signal may be output to each of a plurality of notification devices, or a large number of notification signals may be output to a single notification device. In addition, when an external notification device is connected to the output driver 20, the power from the UPS power supply device 60 may be supplied from the output driver 20 to the notification device via a connection line. Alternatively, the power supply line of the UPS power supply device 60 may be directly connected to the notification device to supply power.

  The wireless communication device 30 is connected to the control calculation unit 50 and performs wireless communication. This wireless communication is configured to communicate with the wireless communication device 30 of another notification communication device 100. The wireless communication method is not particularly limited, and various methods (FM communication, infrared communication, wireless LAN communication) can be adopted.

  The wired communication device 40 is connected to the control calculation unit 50 and performs wired communication. This wired communication is configured to communicate with the wired communication device 40 of the other notification communication device 100. The wired communication method is not particularly limited, and various methods can be employed. For example, various communication lines such as RS232C, an optical fiber, and a LAN using a cable can be used.

  The control calculation unit 50 is connected to the input driver 10, the output driver 20, the wireless communication device 30, and the wired communication device 40, and performs overall signal processing. For example, it is monitored whether or not a signal is input from the input driver 10, the wireless communication device 30, and the wired communication device 40. Details of the signal processing will be described later.

  The UPS power supply device 60 is connected to the input driver 10, the output driver 20, the wireless communication device 30, the wired communication device 40, and the control calculation unit 50, and supplies power from a built-in backup power supply in the event of a power failure.

  Next, the notification communication system will be described. 2 is a diagram showing a configuration example of a notification communication system according to the present embodiment, FIG. 3 is a block diagram of an input notification communication device, FIGS. 4 and 5 are block diagrams of a relay notification communication device, and FIG. FIG. 3 is a block diagram of a notification communication device for output. As shown in FIG. 2, the notification communication system includes four notification communication devices 100A, 100B, 100C, and 100D, an event detection device 200, and a notification device 300. For example, as shown in FIG. 2, the event detection apparatus 200 can output all of the detection signals 1, 2, and 3, two of these signals, or any one of these signals. In response, the notification communication devices 100A, 100B, and 100C relay the above signals, and finally the notification communication device 100D receives all of the notification signals 1, 2, and 3 corresponding to the detection signals. Two of these signals, or one of the signals, is output to make a notification according to the signal input to the notification device. The number of detection signals and the number of notification signals can be increased or decreased in accordance with the actual situation. However, for the sake of simplification of description, these will be described simply as detection signals and notification signals.

The event detection device 200 detects various events and outputs detection signals.
The notification communication device 100A is an input notification communication device, and is configured in detail as shown in FIG. The detection signal from the event detection device 200 is input by the input driver 10 and converted into a digital signal that can be easily processed by the control calculation unit 50, and then output to the control calculation unit 50. The control calculation unit 50 outputs a detection signal to the wireless communication device 30 when the detection signal is input. The wireless communication device 30 converts the detection signal into a communication signal suitable for wireless communication, and transmits the communication signal to the notification communication device 100B by wireless communication.

  In the notification communication device 100A, the input driver 10 and the wireless communication device 30 are used. For example, the input driver 10, the output driver 20, the wireless communication device 30, and the wired communication device 40 are provided with dip switches. In the notification communication device 100A, the input driver 10 may be set as an input device, the wireless communication device 30 may be set as an output device, and the output driver 20 and the wired communication device 40 may be set as unused devices. In this case, the control calculation unit 50 monitors only the input of the input driver 10 and controls the output only to the wireless communication device 30.

  The notification communication device 100B is a relay notification communication device, and is configured in detail as shown in FIG. The wireless communication device 30 inputs a wirelessly communicated communication signal, converts it into a digital signal detection signal that can be easily processed by the control calculation unit 50, and outputs the detection signal to the control calculation unit 50. The control calculation unit 50 outputs the detection signal as it is to the wired communication device 40. The wired communication device 40 is connected to the signal cable 400, converts the detection signal into a communication signal suitable for wired communication, and transmits the communication signal to the notification communication device 100C by wired communication.

  In the notification communication device 100B, the wireless communication device 30 and the wired communication device 40 are selected. For example, the input driver 10, the output driver 20, the wireless communication device 30, and the wired communication device 40 are provided with dip switches. In the notification communication device 100B, the wireless communication device 30 is set as an input device, the wired communication device 40 is set as an output device, and the input driver 10 and the output driver 20 are set as unused devices. In this case, the control calculation unit 50 monitors the input only to the wireless communication device 30 and controls the output only to the wired communication device 40.

  The notification communication device 100C is a relay notification communication device, and is configured in detail as shown in FIG. A communication signal that is wired via the signal cable 400 is input by the wired communication device 40 and converted into a detection signal that can be easily processed by the control calculation unit 50, and the detection signal is output to the control calculation unit 50. The control calculation unit 50 outputs a detection signal to the wireless communication device 30. The wireless communication device 30 converts the detection signal into a communication signal suitable for wireless communication, and transmits the communication signal to the notification communication device 100D by wireless communication.

  In the notification communication device 100C, the wireless communication device 30 and the wired communication device 40 are selected. For example, the input driver 10, the output driver 20, the wireless communication device 30, and the wired communication device 40 are provided with dip switches. In the notification communication device 100C, the wired communication device 40 is set as an input device, the wireless communication device 30 is set as an output device, and the input driver 10 and the output driver 20 are set as unused devices. In this case, the control calculation unit 50 monitors the input only to the wired communication device 40 and controls the output only to the wireless communication device 30.

  The notification communication device 100D is an output notification communication device, and is configured in detail as shown in FIG. The wireless communication device 30 inputs a wirelessly communicated communication signal, converts it into a detection signal that can be easily processed by the control arithmetic unit 50, and outputs this detection signal to the control arithmetic unit 50. The control calculation unit 50 selects a notification signal corresponding to the detection signal, and outputs this notification signal to the output driver 20. The output driver 20 is connected to the notification device 300 and transmits a notification signal to the notification device 300.

  In the notification communication device 100D, the output driver 20 and the wireless communication device 30 are selected. For example, the input driver 10, the output driver 20, the wireless communication device 30, and the wired communication device 40 are provided with dip switches. In the notification communication device 100D, the wireless communication device 30 may be set as an input device, the output driver 20 may be set as an output device, and the input driver 10 and the wired communication device 40 may be set as unused devices. In this case, the control calculation unit 50 monitors the input only to the wireless communication device 30 and controls the output only to the output driver 20.

In the above, the construction example of the notification communication system of the notification communication apparatus 100 of the present embodiment has been described. In this example, the configuration in which the notification communication devices 100B and 100C are employed particularly for relaying has been described, but a large number of notification communication devices 100 may perform relaying wirelessly or by wire.
For example, when relaying wireless → wired → wireless → wireless, communication device 100A for notification of input → wireless communication, communication device 100B for notification of wireless → wired communication, communication device 100C for notification of wired → wireless communication, wireless → wireless A communication communication device 100E for communication and a communication device 100D for wireless → output are installed.

  Here, only the wireless communication device 30 is selected in the notification communication device 100E that communicates wirelessly to wirelessly. For example, the input driver 10, the output driver 20, the wireless communication device 30, and the wired communication device 40 are dip. A switch is provided. In the notification communication device 100E, the wireless communication device 30 may be set as an input / output device, and the input driver 10, the output driver 20, and the wired communication device 40 may be set as unused devices. In this case, the control calculation unit 50 monitors input / output only for the wireless communication device 30.

  In the notification communication devices 100A to 100F, input / output can be selected by the DIP switch. However, input, relay, and output can be set without any input / output setting. For example, if the input driver 10 is connected to the event detection device 200, the input driver 10 is connected to the event detection device 300, the output driver 20 is connected to the notification device 300, and the input driver 10 is connected to the output driver 20. If there is no relay, it can be determined that the relay is used. Therefore, the control calculation unit 50 may perform processing according to whether or not the input driver 10 or the output driver 20 is connected. Further, whether to select wired communication or wireless communication can be determined to be wired communication if the signal line is connected to the wired communication device 40, and wireless communication if not connected, and the control calculation unit 50 can determine whether the wired communication device 40 is connected. You may process so that it may determine according to the presence or absence of the connection in.

Further, when a signal cable is connected to the wired communication device 40 in the relay notification communication device 100, when the input of both the wireless communication device 30 and the wired communication device 40 is confirmed and input from the wired side May be output wirelessly, and when input from the wireless line side, it may be output by wire.
Further, when the signal communication cable 100 is not connected to the wired communication device 40 in the relay notification communication device 100, the wireless communication is dedicated, the input of the wireless communication device 30 is confirmed, and the wireless communication is performed when input from the wireless side. What is necessary is just to make it output wirelessly via the apparatus 30. FIG.
In this embodiment, it is not possible to adopt a form of inputting by wire and outputting by wire, but if necessary, it is possible to install two input and output wire communication devices 40. Such a configuration may be adopted.
As described above, various types of relay communication devices can be used.

  In such a notification communication system, since the notification communication device 100 can be configured only by arranging a plurality of notification communication devices 100 for input, relay, and output, an event that occurred in a remote place at the time of a power failure can be obtained with an inexpensive configuration. A communication system for notification for notification can be provided. In addition, since only wired communication, only wireless communication, or both wired and wireless can be used depending on the communication situation, it is possible to construct a notification communication system according to the actual situation of the installation location.

Next, a notification communication system constructed by installing a plurality of notification communication devices 100 of the present invention at a factory where a factory is located will be described. FIG. 7 is a system diagram of a notification communication system constructed in a business office. In this construction example, when an event detection device 200 is installed in a main substation and a power failure occurs in various production facilities in a factory building, the event detection device 200 of the main substation receiving power directly outputs a detection signal. This is a system for promptly reporting to an alarm device 300 in a guardhouse.
In particular, due to the presence of the office building, the main substation and the guard station cannot be dealt with by wireless communication alone. A system is adopted that is installed in a place where communication is easy and that performs wired communication only between the notification communication devices 100B and 100C, thereby providing a communication path that bypasses the office building that is an obstacle to wireless communication.

  The notification communication device 100A is an input notification communication device and is installed in the main substation. The event detection device 200 is a variety of devices that can detect a power failure, such as a current transformer. The notification communication device 100A converts a detection signal from the event detection device 200 into a communication signal, and the communication signal is transmitted to the office building by wireless communication. It transmits to the communication apparatus 100B for alerting | reporting installed.

  The notification communication device 100B is a relay notification communication device, and is installed on a rooftop of an office building where wireless communication with the notification communication device 100A is possible. The notification communication device 100B generates a communication signal for wired communication from the transmitted communication signal, and the communication signal is transmitted to the notification communication device 100C that is also installed on the roof of the office building by wired communication via the signal cable 400. Send.

  The notification communication device 100C is a relay notification communication device, and is installed on a rooftop of an office building where wireless communication with the notification communication device 100D is possible. The communication device for notification 100C generates a communication signal for wireless communication from the communication signal wired via the signal cable 400, and transmits the communication signal to the communication device for notification 100D by wireless communication.

  The notification communication device 100D is an output notification communication device, and is installed in a guardhouse. Notification communication device 100D receives a wirelessly communicated communication signal and transmits the notification signal to notification device 300.

  When a power failure occurs at a main substation in a factory such as a factory, such a notification communication system 1000 detects a power failure abnormality notified from within the main substation, and relays the detection signal by wire and wireless to protect the guard. It is possible to report to the place. In the guardhouse, it is confirmed that a power failure has occurred by the buzzer and LED display of the alarm device 300, and it is possible to promptly notify the power chief engineer and the electrical equipment maintenance staff even during a holiday or late at night. Recovery and damage can be minimized.

  In the best mode and the first embodiment described above, a power outage was specifically considered as an event. However, it is needless to say that the event is not limited to a power outage. Various events such as fires, water leaks, intrusions, and smoke that are expected to occur can be targeted. If these events are detected in addition to the power failure, the power failure can be detected more reliably.

  In the communication apparatus for notification and the communication system for notification described above, it can be laid by simply carrying out low-cost and simple construction (installing an AC outlet at a position where communication is possible) on existing facilities. It is possible to promptly and thoroughly notify the power failure that has occurred. In particular, since the installation is easy and the cost is low, it is possible to provide a notification communication device and a notification communication system especially for relatively small businesses.
