Description

Information gathering devices, remote monitoring systems, cubicles

[0001] The present invention relates to an information collection device, and a remote monitoring system or cubicle using the information collection device.

[0002] In the field of power receiving and transforming, equipment is monitored to ensure safety. As an example, Patent Document 1 discloses an earth leakage breaker having a function of informing a user.

[0003] Japanese Patent Application Laid-Open No. 2007-299727

[0004] The technology disclosed in Patent Document 1 alerts people in the vicinity when a ground fault is detected. Meanwhile, in the field of power receiving and transforming, there are a wide variety of devices and items to be monitored. For this reason, safety has traditionally been confirmed and ensured through periodic inspections, etc., based on the Electricity Business Act, particularly through direct human inspections.

[0005] However, in the maintenance and inspection of power receiving and transforming equipment, as the equipment ages, the aging of chief electrical engineers, who are legally qualified personnel involved in electrical safety, and a labor shortage due to a decrease in the number of people entering the electrical safety field are becoming serious.For this reason, the smart safety announced by the Ministry of Economy, Trade and Industry, that is, labor-saving in maintenance and inspection work, has become an urgent social demand.

[0006] In light of the above, an object of the present invention is to provide an information collection device that can easily realize remote monitoring of devices.

[0007] An example of a means for solving the above problem is as follows.

[0008] An information collection device having a power supply unit, a communication unit, a control unit, and a terminal block within a housing, and capable of collecting various information from the terminal block in the control unit and transmitting the information from the communication unit.

[0009] According to the present invention, since information on various monitored devices can be collected and transmitted by an information collection device, installation work can be simplified compared to when information is collected and transmitted individually for each device. Furthermore, since information on each monitored device can be checked centrally at the site, monitoring work can be speeded up.

[0010] Further means and effects of the present invention will become apparent throughout the entire specification below.

FIG. 14 is a diagram illustrating an example internal structure of an information collection device according to the present invention. FIG. 15 is a diagram for explaining embodiment 6.

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings as needed.

[0013] The external appearance of an information collection device according to an embodiment of the present invention will be described with reference to Fig. 1. Fig. 1A is a front view, Fig. 1B is a side view, Fig. 1C is a rear view, and Fig. 1D is a top view.

[0014] The information collection device 10 has a front door 13 and a main body 15. The front door 13 may be provided with a handle 11 for opening and closing the front door. An inlet may be provided on the rear side for introducing cables to connect to the monitored device. The inlet may also be provided on the underside of the main body 15. Alternatively, individual holes may be drilled to accommodate the wiring.

[0015] The exterior of the information collection device 10 can also be made of metal. However, as will be described later, in the present invention, a communication unit 20 is installed inside the information collection device 10, and wireless communication is performed using a mobile phone line, a dedicated line, or the like. Therefore, in order to improve the transmission of radio waves, it is more desirable to make the exterior of the information collection device 10 out of a waterproof non-metallic material such as plastic or resin. Examples of desirable materials include polycarbonate, ABS resin, or a combination thereof. In this embodiment, as an example, the exterior is made of a combination of polycarbonate and ABS resin.

[0016] The information collection device 10 can be installed in a variety of ways, but it can be easily installed by, for example, providing a magnet on the back and attaching it to a magnetic flat plate such as the outer panel of a cubicle or switchboard. This also makes it easy to replace.

[0017] 2 is an explanatory diagram of an information collection device according to an embodiment of the present invention with the door open. The front door 13 rotates open relative to the main body 15 via a hinge 52. Reference numeral 50 denotes a main body waterproof section, and 51 denotes a front door waterproof section. When the front door 13 is closed to the main body 15, these two protrusions overlap, thereby providing a waterproof effect against rainwater intrusion. Note that while the illustration shows an example in which the door opens by rotating clockwise, the invention also includes cases in which the door opens by rotating counterclockwise or upward.

[0018] As will be described later in FIG. 3, the information collection device of the present invention is equipped with a communication function. For this reason, it is desirable to take measures to prevent illegal access from outside. As a countermeasure, a function to issue an alarm when the front door 13 is opened unexpectedly may be provided. Alternatively, a door switch may be provided, and when the door is opened, the state of the door switch may be transmitted via the communication unit 20 to the server 60 described later in FIG. 6, and the server 60 may issue an alarm or send an email notification. This is because the security of the device can be improved.

[0019] 3 is an explanatory diagram of the device configuration of an information collection device according to an embodiment of the present invention, and explains the devices built into the main body 15.

[0020] The information collection device 10 includes a communication unit 20, a control unit 21, a power supply unit 23, and a terminal block 24. If the information collection device 10 includes a display unit 22, it is more preferable because it allows the information collection device 10 itself to display various information.

[0021] The communication unit 20 is, for example, an industrial wireless router, and transmits the information collected by the information collection device 10 to the outside via a mobile phone line.

[0022] The control unit 21 is a part that aggregates, formats, or organizes various pieces of information input to the terminal block 24 so that the information can be transmitted to the outside via the communication unit 20, and for the purpose of this processing, it has an arithmetic circuit such as a CPU and a temporary storage medium such as a memory. The memory may be built into the CPU.

[0023] The display unit 22 may be provided integrally with the control unit 21 or separately. It is a so-called display. It is a display unit for checking the information collected by the information collection device 10, the operating status of the information collection device 10, etc. on the spot. Various types of displays, such as a liquid crystal display or a self-luminous element, can be applied. In either case, in order to use the display unit 22 also as a simple operation device, it is desirable that the display unit 22 has a touch panel. Furthermore, it may have a function for switching between multiple pieces of information, be able to display imported information, and be able to display maintenance information.

[0024] The control unit 21 and the display unit 22 may be combined or integrated into one unit and called a monitoring unit.

[0025] The power supply unit 23 is a part for supplying power to the communication unit 20, the control unit 21, the display unit 22, etc. Note that this power supply unit 23 may have a simple configuration of only a breaker. It may also have an outlet, a voltage conversion circuit, etc. Furthermore, it may also supply power to external devices connected to the information collection device 10.

[0026] The terminal block 24 is used to connect to external devices to be monitored and input information from the external devices to the information collection device 10. This has the advantage of facilitating wiring work from various sensors. The information input to the terminal block 24 is sent as an input signal 30 to the control unit 21. The control unit 21 aggregates, formats, or organizes the information, and then sends it as a transmission signal 31 to the communication unit 20, from which the information is transmitted to an external server or the like.

[0027] The cables connected to the input side 24A of the terminal block 24 may be collected and connected to a connector, which can facilitate the wiring work.

[0028] 4A is an explanatory diagram of a terminal block according to an embodiment of the present invention, where 24A is the input side and 24B is the output side.

[0029] FIG. 4B is an explanatory diagram of input signals to a terminal block in one embodiment of the present invention. Examples include voltage V, current I, low-voltage leakage current detected by ZCT, contact status, pulse signal, analog input, and temperature input. Examples of voltage include R-S and S-T, and examples of current include R, S, and T phases. Analog signals also include minute currents such as DC 4 to 20 mA. Temperature includes resistance temperature detector values ​​such as Pt 100 Ω. Note that the input signals are merely examples. This is not limited to cases where terminals corresponding to all signals are provided or where inputs corresponding to all signals are made, but also includes cases where some of those terminals are provided or some of those signals are input.

[0030] It is also possible to input analog or digital signals from various sensors, the concentration of combustible gases contained in the insulating oil of transformers, and values ​​from sensors attached to other equipment.

[0031] The information collection device 10 in this embodiment can also be described as an information collection device equipped with a signal acquisition unit that acquires information that contributes to preventive maintenance, such as the electrical quantity and environmental conditions of equipment (parts) that cannot be easily accessed while charging, as electrical signals from various sensors, a control unit that organizes the acquired information, and a communication unit that outputs the acquired information to the outside.

[0032] The information collection device of this embodiment integrates the functions necessary for monitoring multiple devices into a single housing, making it easy to remotely monitor the devices. While the information collection device of Patent Document 1 only alerts the surrounding area when a ground fault is detected, the information collection device of this embodiment makes it easy to remotely monitor the devices. Furthermore, even if the number of devices or items to be monitored increases, the information collection device enables remote monitoring without the need for additional equipment or functions, making it a key tool for reducing the labor, costs, and efficiency of monitoring operations. Furthermore, since the necessary functions are contained in a single housing, installation is easy and remote monitoring can be quickly implemented.

[0033] This embodiment is basically the same as embodiment 1. Fig. 5 is a diagram corresponding to Fig. 4 of embodiment 1. In contrast to Fig. 4, Fig. 5 shows an example in which image information 33 from a camera 40 is sent as image information 32 to a communication unit 20 via a wired or wireless hub 26, and the camera image is then transmitted from the communication unit 20 to the outside.

[0034] This includes not only cases where image information and the like is transmitted directly from the hub 26 to the communication unit 20, but also cases where it is transmitted to the control unit 21. However, because the image information from the camera 40 contains a large amount of information, the arithmetic unit installed in the control unit 21 may not have the performance to handle complex processing, or installing a arithmetic unit capable of handling this would be expensive. Therefore, it is desirable to transmit the image information from the camera 40 from the communication unit 20 to an external device such as a server basically as is, without processing, or after undergoing only the minimum conversion necessary to make it communicable.

[0035] In this embodiment, in addition to the effects of the first embodiment, it is possible to realize image monitoring using camera images.

[0036] This embodiment describes the external information transmission of the information collection device of the first or second embodiment, and the resulting remote monitoring or maintenance.

[0037] FIG. 6 is an explanatory diagram of remote monitoring using the information collection device of the present invention. Information collected by the information collection device 10 is transmitted to a server 60 via a communication line 70. The server 60 may be implemented using specific hardware or on the cloud. The communication line 70 is preferably a dedicated line other than the Internet, such as a mobile phone line or a dedicated line. The information exchanged between the information collection device 10 and the server 60 is raw data, and may include sensitive information that can be interpreted to reveal the operating status of a company's equipment or the status of its activities. Therefore, it is desirable to ensure high security.

[0038] The information may be output to various destinations as required, such as direct output or connection to a customer's PC or the like via a WIFI function.

[0039] Here, for the purpose of reducing the amount of information or the number of packets transmitted from the communication unit 20 of the information collection device 10 to the server 60 via the communication line 70, the control unit 21, the communication unit 20 itself, or a dedicated processing device may be provided separately inside the information collection device 10 to perform data compression processing and transmit the compressed data to the server 60. This is because the amount of data transmitted to the server 60 can be reduced, making it possible to prevent congestion and delays in communication traffic and the expansion of the storage medium on the server 60 side.

[0040] Furthermore, the control unit 21, the communication unit 20 itself, or a separate dedicated processing device provided inside the information collection device 10 may perform desired processing such as pattern recognition or template matching on the data obtained from the camera 40, and transmit only information and color information about a specific object (suspicious person, animal) to the server 60. Alternatively, only data from a specific time period may be transmitted. This is because the amount of data transmitted to the server 60 can be reduced, thereby preventing congestion and delays in communication traffic and the expansion of the storage medium on the server 60 side.

[0041] The data that has not been transmitted to the server 60 may be deleted after being stored for a certain period in the control unit 21, the communication unit 20 itself, or a separately provided dedicated processing device. Alternatively, the data may be deleted immediately after being transmitted to the server 60.

[0042] Data stored for a certain period of time in the control unit 21, the communication unit 20 itself, or a separately provided dedicated processing device can be transmitted to the server 60 later along with time information in response to a request from an external source such as the server 60, a request from the control unit 21, or a program within the information collection device 10, as long as it is within the storage period, i.e., if it is in a temporary storage state.

[0043] Based on information from the information collection device 10, the server 60 monitors the operating status and facility status of each device that is the monitoring target of the information collection device. This type of monitoring realizes remote monitoring. Such monitoring work is performed in the form of the server 60, on standalone hardware, or by monitoring software built on the cloud. This monitoring work becomes a business called a remote monitoring service, and replaces conventional human monitoring to the extent possible. The remote monitoring service can also include a predictive diagnosis service. Note that AI may be used for this remote monitoring and predictive diagnosis service.

[0044] The server 60 stores the information from the information collection device 10 on its hardware or on the cloud, and a user who owns the monitored device can access the server 60 from a user terminal 61 via the Internet network 71 to obtain the necessary information. 72 denotes user terminal compatible information.

[0045] This allows users to access the information they need from anywhere, and also allows them to easily check and monitor the operating status and condition of their own equipment remotely. In other words, it allows for visualization.

[0046] When an abnormality or a sign of an abnormality occurs in the monitored equipment, the server 60 automatically notifies the user by e-mail or the like, thereby supporting the user's equipment monitoring.

[0047] Reference numeral 62 denotes a management company terminal. Depending on the type of contract, this may be a terminal of a company that operates monitoring software on the server 60 or a company that undertakes remote monitoring services. Reference numeral 73 denotes management company terminal correspondence information.

[0048] Figure 7 is a diagram based on Figure 6 that explains the situation when a sign of an abnormality is detected. The server 60 detects the sign of an abnormality and contacts the user by email or issues an alarm to the user terminal 61. The user makes an inquiry 75 to the management company by phone, email, or using the inquiry function on the user terminal 61. Note that this inquiry 75 also includes cases where a response request is made.

[0049] The management company checks the situation on the management company terminal 62 and contacts the user as support 74. Contact can be made in various forms, such as by telephone, email, or via the user terminal 61. The content of the support can vary depending on the situation, such as suggestions for how to deal with the problem or suggestions for equipment repair. In addition, with regard to such support suggestions, many cases from many users are accumulated in the server 60, and as the number of managed devices increases and as time passes, the support capabilities of the management company improve.

[0050] In this case, if a judgment is made based only on information from a single device, as in the past, it may take time to identify the true cause, but by using the information collection device 10 of the present invention, the cause can be investigated while simultaneously checking or evaluating various pieces of information, which has the advantage of enabling the cause to be identified and a response to be made quickly.

[0051] Furthermore, conventional electrical safety personnel's responses have been based on tacit knowledge, so to speak. However, by using the information collection device 10 of the present invention, it is possible to store, manage, judge, and accumulate response cases in the server 60, and convert this information into collective intelligence, so to speak. This not only contributes to labor savings, but also has the advantage of realizing a high level of standardization of response content.

[0052] 8 is an example of a management screen on the user terminal 61. Reference numeral 80 denotes an example of a screen display, 81 denotes a driving status display area, 82 denotes a detailed status display area, 83 denotes a target selection area, 84 denotes a camera image selection area, and 85 denotes a support call area.

[0053] The user can get an overview of the equipment's operating status in the operating status display area 81. As an example, the operating status may be displayed in an easy-to-understand manner using colors or icons. The figure shows an example of icon display, with 90A being a warning icon, 90B being a caution icon, and 90C being a normal icon. Currently, the normal icon 90C is shown lit up.

[0054] By selecting the target selection area 83 with a mouse or the like, it becomes possible to select the target equipment to be displayed in the operating status display area 81. Even if another target equipment is displayed in the operating status display area 81, if an emergency trouble or abnormality sign is detected in another target equipment, the screen will automatically switch to display that equipment.

[0055] 84 is a camera image selection area, which switches between camera image display and emergency display. If camera images are displayed all the time, it takes up space in the display area for other information, so this is made selectable. 85 is a support call area. Clicking this allows you to contact the management company or request support via 75 in Figure 7. It may also be automatically linked to web chat or web conferences.

[0056] A detailed status display area 82 displays detailed status and numerical values.

[0057] 9 is an example of information displayed in the detailed status display area 82. Various pre-set information can be displayed. The items shown in FIG. 9 can also be referred to as the information collection items of the information collection device 10 in the first and second embodiments. However, it is not essential that all items are monitored simultaneously; what is meant is that the collection of this information is prepared in advance.

[0058] As described above in detail, in this embodiment, or by using the information collection device of embodiment 1 or embodiment 2, information on various monitored devices can be aggregated and transmitted by the information collection device. This makes it possible to simplify installation work compared to when information is collected and transmitted individually for each device. Furthermore, since information on each monitored device can be centrally checked on-site, monitoring work can be expedited.

[0059] 10 shows an example of the information collection device 10 according to the first or second embodiment. The built-in devices are all unitized. This allows the internal components of the information collection device 10 to be easily attached and detached.

[0060] The information collection device 10 also has a wiring routing section 55, through which various wiring is routed, thereby preventing the wiring from becoming disorganized and improving the cooling efficiency of the information collection device 10.

[0061] In this embodiment, in addition to the effects described in the first to third embodiments, the information collection device 10 can be easily assembled, modified, and remodeled to improve performance.

[0062] This embodiment is basically the same as the first and second embodiments.

[0063] This embodiment is an example of a case where the information collection device 10 is installed inside a separate metal housing. The separate metal housing may be, for example, a switchboard or a cubicle. In this case, the switchboard or the cubicle housing is made of metal, which blocks or weakens radio waves from the communication unit 20 built into the information collection device 10.

[0064] Therefore, in this embodiment, an external antenna is provided that is connected by wire to the communication unit 20, and the external antenna is attached to the outside of a separate metal housing. The communication unit 20 and the external antenna are connected by passing a wire for wired connection through a cutout in a part of the door gasket of the separate metal housing. The area near the cutout is sloped so that the outside is lower, thereby preventing rainwater from entering.

[0065] A sixth embodiment will be described. This embodiment is characterized in that the active component of leakage current is monitored inside the information collection device 10 using the obtained signal. More specifically, for example, a control unit 21 disposed inside the information collection device 10 obtains the active component of leakage current using a voltage signal obtained from a terminal block and a signal from a ZCT (zero-phase current transformer).

[0066] 11 is a diagram for explaining the functional configuration of this embodiment. Although not shown, power can be supplied from the power supply unit 23 so that each component in FIG. 11 operates correctly.

[0067] The voltage signal 108 and the signal 109 from the ZCT are signals obtained from a measurement object (circuit under test) outside the information collection device 10 .

[0068] A zero-crossing detection circuit 104 detects zero-crossing points in the voltage waveform of the object to be measured and generates a sampling start signal 110. A storage unit 105 stores digital data of a sine waveform in which the effective value of the sampling start signal 110 is 1. An amplifier circuit 101 amplifies a signal 109 from the ZCT.

[0069] The digital sampling unit 102 performs digital sampling on the amplified leakage current signal waveform.

[0070] The memory unit 103 stores the sampled digital waveform. The stored digital waveform can be used for power calculation together with the sinusoidal waveform data with an effective value of 1 stored in the memory unit 105.

[0071] Leakage current power P is the product (power factor) of voltage V, current I, and phase angle φ. The calculation formula can be expressed as P = VI cos phi (phi is the Greek letter). The leakage current power P divided by voltage V is the active current. In addition, leakage current power p in the sampling method can be expressed as the average of the product (p = vi) of the instantaneous values ​​of voltage v and current (leakage current) i. This average calculation is performed at 106.

[0072] The effective portion of the leakage current is obtained by dividing this average leakage current power p by the voltage v. This calculation is performed at reference numeral 107. The obtained effective portion of the leakage current is output to the outside of the information collection device 10. In this way, it becomes possible to detect undesired incidents early or capture their symptoms while reducing the processing load on the external server.

[0073] Furthermore, information before obtaining the effective component of leakage current may be transmitted to an external device, and analyzed by an external cloud server, etc. This information includes at least one of information on the zero-crossing point, a sampling start signal 110, digital data of a sine waveform with an effective value of 1, a digital waveform stored in the memory unit 103, and average data obtained by the code 106.

[0074] The effective component of the leakage current may be obtained by any other feasible method, not limited to the above method, for example, by the following procedure.

[0075] Process 1: Separation and removal of harmonic components by Fourier analysis. This process involves extracting only desired frequency components, for example, 50 Hz and 60 Hz components that indicate the power supply frequency, from the signal 109 from the ZCT (or other signals).

[0076] Process 2: Separation and removal of desired components (e.g., capacitor components) by phase vector analysis.

[0077] It is also within the scope of the disclosure of this specification that the frequency components or component components separated by the above-described processes 1 and 2 may be output to the outside of the information collection device 10 and analyzed by an external terminal such as a cloud server. It is also within the scope of the disclosure of this specification that the effective portion of the leakage current may be obtained on the cloud server side.

[0078] As described in detail in each of the above embodiments, the information collection device 10 of the present invention can centrally manage the collection and transmission of information necessary for monitoring operations with just one device, making it a trump card for remote security and labor-saving security operations, and meeting the needs of society.

[0079] Furthermore, while the ideas and concepts of the present invention have been described using various examples, the scope of the present invention also includes cases where the examples are combined to realize the invention. Furthermore, as long as the disclosed ideas and concepts are used, the scope of the present invention also includes modifications and similar examples.
