Description

  The present invention prevents the surge current from GPS / terrestrial digital broadcasting and mobile phone radio waves and noise (lightning / static electricity / magnetism / electromagnetic waves) from entering all the wires, preventing the destruction of electronic components in electronic devices. In order to prevent malfunctions of software and noise, noise filters and noise counters in power circuit distribution boards and outlet circuits that are protected against noise (lightning, static electricity, electromagnetic waves) by SPD (gap, zinc oxide, and other elements) The circuit and the SPD circuit are connected in parallel, and are also mounted on the power circuit inside the electronic device, and the SPD (gap, zinc oxide or , Other elements) are connected in parallel, and if there are multiple floors inside the building, the horizontal grounding pole and the vertical grounding pole are near-by grounded, and the vertical ground between the buildings on the site All the earth electrodes in the horizontal formation to the equipotential bonding earth ground electrode, which is near-by-grounded, and all the noise is passed to the equipotential bonding earth electrodes of the horizontal and vertical formations in the earth, in all computers, mobile phones and EVs. The present invention relates to a system for erasing data stored in a storage device in a computer and removing a computer virus. In particular, data stored in a hard disk (HDD) or solid state drive (SSD) is easily deleted in a short time. In addition, the present invention relates to a system that protects a computer, a portable terminal, a television with a storage device, a precision device with a communication system, and a tablet terminal by fundamentally deleting a computer virus.

  Currently, as a power generation technology for building a low-carbon emission society, solar power, wind power, hydropower, hydrogen, geothermal, water level tidal power generation systems that use natural energy, and microwaves coming from space are received by antennas. A system for converting the radio wave into electric power has been developed.

  On the other hand, automobiles, ships, aircraft, etc., equipped with engines driven using fossil fuels such as gasoline, are becoming increasingly electrified by storage batteries and motors, or hybridized by combining fossil fuel engines and motors. Yes. By the way, in the United States, a technology for managing an experiment of power supply for managing generated power by optical communication or wireless using an optical communication or high-speed communication network has already begun.

In this way, with the promotion of the removal of energy resources from fossil fuels, new problems have arisen when power generated by natural energy is stored in storage batteries or managed by optical communication or wireless systems. .

The problem is
(1) In Japan and overseas, especially in Japan, lightning countermeasures have been legalized in recent years, and SPD (Class 1 and Class 2 connected in parallel) are installed in the distribution board, and equipotential bonding earth bars are installed. It was obliged to install. This is a law to attach an equipotential grounding electrode inside the outlet branched from the distribution board, but the power circuit in the electronic board inside the OA tap outlet has a low level surge current or noise current below static electricity, Only a surge absorber SPD is installed that protects against the noise current when the breaker is on and off. Therefore, a circuit in which elements having large capacitances (large, medium, small, and extremely small) that can control a high level and a low level of excess current of lightning, static electricity, and electromagnetic waves are not mounted.
Moreover, in the cable circuit for connecting the AC circuit wires, one or a plurality of SPDs having the same operating voltage, which are designed on the premise of a base operating with a conventional voltage, are attached between the positive and negative electrodes. At present, lightning surges, electrostatic surges, and electromagnetic waves are also connected to a single earth electrode with equipotential bonding connections in PCs, tablet terminals, mobile phone smartphones, LED lighting, solar power generation bases, wind power generation bases, and EV charging systems. No measures are taken to allow surge current to flow.
(2) In order to reduce global power consumption, the power consumption of parts in electronic boards has been improved and improved to low voltage and low current specifications. While radio waves are transmitted, data intrudes from electric wires and malfunctions in electronic equipment, it is vulnerable to excess current such as static electricity and lightning surge current, hackers against information management data, Basic measures against computer viruses transmitted by crackers and the like are scarce. Furthermore, the noise current from the inverter circuit for storing the direct current generated from the wind power generation / solar power generation in the building or home from the neighborhood in home / business storage batteries (including EV / PHV) and converting it into alternating current However, no countermeasures are taken in the board of the electronic device because the frequency varies depending on the region where the power generation industry, EV industry and electronic equipment industry are installed.
Therefore, the frequency transmitted from the inverter circuit for storing in the storage battery the digital broadcasting radio wave, the mobile phone radio wave, and the direct current generated from the solar power / wind power generation that converts direct current to alternating current or alternating current to direct current, and thunder・ Countermeasures against electrostatic surge currents are not enough for power circuits and communication, sensor circuits, surveillance cameras, and other power supply circuits, so hardware as well as software has been destroyed.
In addition, the current status of computer viruses entering the storage device that manages the information and communication data, which is the heart of the smart grid system, and destroying the data as a method for disposing of the storage device that has received the virus. In order to achieve this, it is mechanically pulverized, and a new data destruction technique is indispensable from the viewpoint of adversely affecting the body of the pulverizer.

  The present inventor has applied for a patent for lightning countermeasure technology of an optical communication system and technology for preventing static electricity charged on a human body from being discharged to an electronic device from 2000 to 2003. Patent Document 1 proposes a technique for reliably flowing (grounding) currents having different surge current capacities to the ground. In addition, lightning currents in buildings are allowed to flow evenly over the ground, and excess currents such as electromagnetic waves and static electricity are connected to free access iron plates, floor rebars and beam rebars, and steel frames in the floor. By connecting the reinforcing bars and the earth plate of the earth pole in parallel, the foundation piles are connected to the free-access iron plates in the building, the floor reinforcing bars and the beam reinforcing bars, the steel frames, the column reinforcing bars, the column steel frames, and buried in the ground. Patent Document 2 also proposes a technology that can protect an electronic device in a building by connecting an internal reinforcing bar and a ground plate of a ground electrode in parallel.

On the other hand, the “equipotential bonding method” promoted by the IEC standard has been adopted worldwide since 2005, but it is difficult to adopt the IEC standard as it is in Japan and other Asian countries where earthquakes frequently occur. is there. Accordingly, the present inventors, when bolting nut Damping device between the skeleton and the basal, with one ground cable length took sign of shaking width caused by an earthquake to the bolt and the base side of the skeleton side Lightning strikes on buildings and solar power generators by connecting between the damping bolts and the fixed bolts of the swing damper and connecting the earthing pole embedded in the ground and the metal fittings in the foundation pile. Protects against electric current or electronic equipment placed indoors, EV charging equipment installed outdoors and EV, lightning surge current flowing in cables or wires connected to PHV, static electricity that is charged and discharged by contractors, A system that generates power in cooperation with electromagnetic waves and magnetic fields and stores the generated electricity in a storage battery has also been proposed.

  However, as described above, in recent electronic parts, the voltage and current values are set to be extremely low, and conventional SPD (lightning arrester) class 1 and class 2 elements do not fit in the electronic board and cannot be stored. In the first place, there is a problem that the response start voltage and the response speed are not strictly considered.

  Furthermore, CPUs, memories, solid state drives (SSDs), and hard disks (HDDs) in electronic devices are shifting to compact and energy-saving types and require less power consumption. Noise countermeasures for power generation systems that supply power to electronic devices, distribution boards and outlets that distribute the generated power, and power supplies inside electronic devices are combinations of large, medium, and small elements of noise filters and SPD elements. It is preferable to carry out by. However, even if the size of the SPD element is large enough to be mounted inside the electronic device, the reflected wave (continuous current) penetrates the electronic board, and a surge current flows through the power circuit of the electronic device. The electronic components in the electronic board are adversely affected, and there are problems such as destruction at an instant, destruction at the elapse of time, and terminal deterioration due to corrosion. For this reason, it has been avoided to install SPD elements of 10/350 μs, 8/20 μs, and 1.2 / 50 μs in the electronic substrate. In other words, although electronic circuit designers are obsessed with techniques for reducing the power consumption of electronic components, they are not interested in destroying a substrate due to noise current. Therefore, if the shielded wire was laid on the wire in the building, and if it was inside the distribution board, outlet circuit, and LED lighting, all noise countermeasures were also taken in the electronic board, and it flowed to the intrusion prevention and avoidance circuit Shielding, holding, and earth grounding, which do not allow all noise to enter from the electric wire, are now indispensable for zone defense of systems that can see this.

  One problem in this situation is countermeasures against computer viruses in data centers, PCs, and mobile phones. For example, when managing the amount of power generated by a solar power generation device (including wind power generation, vibration power generation, etc.) installed in a general household, there is a risk that the power generation amount data may be rewritten by a cyber attack. That is, the billing data is rewritten and a problem occurs in settlement.

  Conventional computer virus countermeasures include, for example, a step of selecting and loading an operating system in which an anti-virus module is arranged from among a plurality of operating systems of the computer when the computer is started, and an anti-virus module. A system including a step of detecting a computer virus in a partition of a plurality of operating systems other than the operating system in which the virus module is arranged, and deleting or isolating the detected computer virus has been proposed (see Patent Document 3). ).

Japanese Patent No. 4441724 Japanese Patent No. 4599884 JP 2009-37618 A

  However, it is extremely difficult to specify the time when a computer virus was transmitted and the device from which it was transmitted, and every time a new virus occurs, it is a drastic measure to counter it with anti-virus application software. Is hard to say.

  The inventor stores electricity generated by solar power generation, wind power generation, noise power generation, optical fiber power generation, vibration power generation, and the like in a storage battery, and flows electric power from which noise current has been removed to an AC circuit. The PHV power circuit is open to lightning (lightning current, induced lightning), switching surges when the power is turned on and off, and all surge currents of static electricity and electromagnetic waves (radio waves of digital terrestrial broadcasting and digital mobile phones). In addition, the conventional SPD (lightning arrester) element has designed the lightning current and the response voltage to the induced lightning surge current. However, the lowest response is achieved by reducing the operating voltage by developing an electronic energy-saving board and components. It is pointed out that the starting voltage is too high and the response speed is slow. Such a system equipped with a storage battery, motor, computer and communication system and monitored in the data center is vulnerable to excess current. In other words, the memory in personal computers and automobiles is unprotected against surge currents such as lightning, and the conventional SPD (lightning arrester) element has a response start voltage level (1400 V to 5000 V) against the surge current that is too high. Point out that the response speed is slow. Moreover, because digital terrestrial broadcasting and mobile phones have shifted to technology that transmits video from phone calls and text transmission, the rooftop of a nearby building can transmit radio waves in a high-frequency / ultra-high frequency band that is close to a straight line. Is always transmitted as if the lightning surge current is discharged. The closer the radio station is, the more radio waves enter the adjacent building and intrude from the electric wire, which adversely affects the electronic board, and bugs of unknown cause are beginning to occur not only hardware but also software.

  The present invention includes all noise and computer viruses that attack stored data in electronic devices such as personal computers in precision machines, all personal computers, LED lighting and communication networks, and EV and PHV storage devices. When a surge current containing lightning flows through a cable that communicates with the rated voltage current at an ordinary (intentional) time, it is blocked by the SPD, and the voltage at which the SPD does not respond only when a virus enters. This is a system that destroys and disinfects only virus data by discharging current and destroys and erases stored data in storage devices such as HDDs and SSDs that are discarded. Another object of the present invention is to provide a useful computer virus intrusion prevention system and a storage system data deletion system.

Therefore remove system memory storing data of an electronic apparatus of the present invention, a power supply circuit, a counter circuit having a counter display section, electrons storage peripherals including hard disk (HDD) or solid state drive (SSD) is mounted the AC circuit connection terminals of the two poles arranged on the electronic board of the appliance (single-phase three-wire) or tripolar (three-phase three-wire),
An ultra-high frequency noise filter, a first lightning arrester that reacts from a protection level 230V of class 3 response start voltage, a second lightning arrester that responds from a protection level 2.5KV of class 2 response start voltage, and class 1 In parallel with a third lightning protection element that reacts from a protection level of 1.4 KV of the limit voltage of
A surge current discharge circuit capable of discharging to the storage device is attached to the electronic board,
When a surge current including lightning flows, the surge current is blocked by the first to third lightning arresters, and only when virus data enters the first to third By discharging voltage and current to the storage device that does not react to the protection level of the lightning protection element ,
The first feature is that virus data stored in the storage device of the electronic device is destroyed .

In addition, a lightning arrester (rated 1.2 / 50 μs or rated 1.2 / 50 μs or a rated flashover voltage that reacts from 230 V and discharges to an impulse discharge current of 20 KA due to the size of the SPD element connected in parallel with the low frequency / high frequency noise filter in the power circuit. And a combination of a plurality of lightning protection elements selected from lightning protection elements having a rating of 8/20 μs or 10/350 μs capable of discharging to a flash discharge voltage of 40 KA by reacting from a flashover voltage of 1.4 KV. Two features.

Installed in a distribution board, lighting circuit or cooler circuit, EV / PHV charging box or vehicle connected to a power circuit drawn from an electric power company or a power circuit connected to photovoltaic power generation / wind power generation / storage battery It is provided in a network circuit or a network communication circuit connected to an electronic device or a television .

  Attach multiple surge current avoidance elements with different response start voltages to the communication network or TV cable or wireless cable and power circuit, and connect the grounding poles with different grounding resistances to near-by-earth, as well as communication, antenna, and sensor DC Attach multiple surge current avoidance elements with different response start voltages to the circuit and power circuit cable, connect the negative pole of the surge current avoidance element to the negative pole of the surge current avoidance circuit of the power circuit, and counter the equipotential bonding cable A fourth feature is that a circuit current sensor is attached, a counter display unit and a discharge circuit switch are attached, and a surge current is discharged to the storage device to destroy stored data.

  A storage device of at least three servers is installed in a server rack that stores network communication equipment, and a second storage device and a first storage device connected to a communication cable drawn from outside are connected to the first storage device via a hub. When a third storage device is arranged and a computer virus enters the server, one of the three storage devices is turned off, and one of the remaining two devices is turned on. A fifth feature is that all the stored data of the server is destroyed by discharging an excessive current to the storage device into which the virus has entered, and at the same time, the stored data is backed up to the storage device turned on.

  The sixth feature is that the stored data is destroyed by discharging a surge current having a voltage lower than the response start voltage of the lightning arrester arranged between the cables connected to the network hub.

  A seventh feature is that a plurality of connectors are branched from the surge current discharge circuit, a storage device to be disposed of is connected to each of the connectors, and then discharged, and data stored in the plurality of storage devices are simultaneously erased.

  In other words, electronic hardware and data software are protected from computer viruses, digital broadcast radio waves, mobile phone radio waves, GPS radio waves, and radio wave frequencies emitted from solar and wind power inverters. In order to disinfect the virus fundamentally only, the surge current such as lightning current is intentionally discharged directly to a storage device such as HDD or SSD, or connected to a communication cable. By discharging or radiating electromagnetic waves, unnecessary stored data including computer viruses is destroyed and erased, and the electronic board and necessary data are automatically backed up and protected.

The present invention has the following excellent effects.
(1) Wired / wireless (including mobile phones), low-frequency / high-frequency / ultra-high frequency of all noise in EV and PHV power circuits, including coolers for electronic devices connected to the network, TVs and LED lighting Blocks hardware (electronic parts) and software data in electronic devices from frequency bands and low surge currents (switch opening / closing surges), medium pressure (electrostatic surges), and high voltage (lightning surges), and is connected to communication systems Protects the DC power supply circuit transmitted to the cable and the stored data in the storage device inside the electronic device with a surge current that attacks the computer virus, and destroys only the virus data by discharging a surge voltage that does not respond. It can be erased fundamentally.
(2) Data stored in storage devices such as HDDs and SSDs that are disposed of can be easily deleted without relying on physical destruction means, and can be used for information management by preventing information leakage. It is.

  The present invention includes a plurality of types of lightning protection devices having different response start voltages, noise filters, counter circuits, and lightning arresters installed in an electronic device connected to an outlet, and in an electronic substrate of a power generation device (including a storage battery), and noise A filter is installed inside the distribution board, and is further built in the outlet circuit or OA tap outlet circuit, and an element having a different removable capacity is inserted into the outlet circuit or OA tap outlet circuit. The gist is to install all frequency noise and lightning / static electricity / electromagnetic wave surge suppression devices at multiple locations such as electronic devices, LEDs, storage batteries, and EVs.

  A plurality of motherboards are supplied in a power supply circuit box of a circuit in which an AC circuit of an electric circuit inside an electronic device and an element having a different response start voltage are connected in series or in parallel to the DC circuit and flow to the equipotential bonding earth electrode. Because of the structure of only the power supply circuit, the response start voltage of the SPD attached to the power supply and communication cable is connected to the communication network and the data collected by data communication is connected to the communication terminal of the hard disk (HDD) or solid state drive (SSD). By discharging the low area or passing current through the antenna in the case, the lightning surge current during data communication does not destroy the power circuit and communication circuit board, but within the data communication algorithm promised for data communication In terms of time, only data that takes too much time is discharged to the communication cable and the data is destroyed.

  Therefore, an arbitrary number of network circuits, for example, three or more A, B, and C circuits are installed automatically or manually, and the servers of the three systems connected to each circuit can be switched in order. If the data communication system of the C network and the C server circuit is put on standby while the B server is receiving the next data, the data received in is switched to the B network. Even when the current flows through the communication cable between the power circuit and the power circuit, it responds and flows through the earth ground electrode, protecting the substrate and communication data.

  If data enters a virus and takes a certain amount of communication time, the noise current below the lightning surge will be broken by the communication cable or hard disk (HDD), or the hacker's algorithm will be destroyed with a current that does not destroy the data. Providing a system that protects electronic equipment and leads to a system that can protect against cyber attacks. In other words, from the technology that throws away the noise current to protect the electronic board from lightning, static electricity, and electromagnetic waves, it is also possible to recycle and generate power from the discarded noise current, applying the noise current of the electronic board to the power generation system, The SPD technology is applied to a technology that discharges the limit voltage as a noise current against hackers and crackers. In addition to computers and communication devices, home appliances and power generation systems are also equipped with storage devices that store and communicate data. However, data stored in storage devices in the event of a failure or replacement How to erase will be a major issue in the future. Compact size mobile phones and tablet terminals spread around the world, and GPS, EV and PHV data erasing technologies installed in vehicles have not been established at this stage.

Embodiments of the present invention will be described below based on examples shown in the drawings.
For example, as shown in FIG. 1 (a), a noise / leakage counter circuit, a low frequency noise filter and an SPD (6a, 6b, 6c) are housed in a distribution board, and a noise / leakage counter circuit is placed in an OA tap outlet. By attaching a high-frequency filter and SPD, the electronic equipment can protect against lightning and static electricity, but when the super-high frequency noise flows, the filter does not react, only the super-high frequency noise flows in the board, the electronic board malfunctions, and the data Destroyed.
In particular, because digital terrestrial broadcasting and mobile phones have shifted to technology that transmits video with a large amount of data from call and character transmission, radio waves are transmitted in high frequency and ultra high frequency bands that are close to straight lines. As a property of the radio wave, a reflected wave is also generated, which easily flows to the electric wire in the building near the transmitting station.
In other words, the current power situation is that there is an accident in which noise current from the inverter of the solar power generation or wind power generation system affects the electronic equipment in the company building or home from the vicinity on the rooftop, on the site, or in the vicinity. It occurs frequently. As shown in FIG. 1, the storage data erasure and computer virus erasure system of the storage device according to the present invention includes a low frequency noise filter with a noise / leakage counter circuit inside the distribution board and an OA tap outlet inside the noise / leakage leak. A low-frequency or high-frequency noise filter with a counter circuit and an SPD are stored in an OA tap outlet, a power circuit 1 inside the electronic device, a counter circuit 2 with a counter display 2a, a hard disk (HDD), a solid state drive (SDD), etc. A high-frequency noise filter or a super-high-frequency noise filter and a plurality of SPDs having different ratings are connected to a two-pole or three-pole AC circuit connection terminal 5 arranged on an electronic substrate (motherboard) 4 of an electronic device on which the storage device 3 is mounted. While connecting the lightning arresters (SPD) 6a, 6b, 6c in parallel, It is constructed by the attached surge current discharge circuit 7 to the electronic substrate 4 in the storage device 3. In addition, in FIG. 1 (a), an outlet receptacle circuit in which a ground electrode is attached to this SPD circuit is connected in parallel, and an outlet into which an electronic device plug is inserted (it is also possible to connect a lightning arrester for a communication cable and a connection connector in parallel). It is configured together.

As shown in FIG. 2 (a), or mounted inside the outdoor box for connection to the vehicle, or the outdoor outlet circuit, in order to protect the double in both vehicles (EV · P H V) 8 , the vehicle or provided a surge current discharge circuit 7 in the mounted electronic device-accommodating box in (EV · P H V) 8 , as shown in FIG. 2 (b), the power supply circuit 1 of a personal computer (PC) 9, counter A circuit 2 and a surge current discharge circuit 7 are provided for use.

Here, the SPD (6a, 6b, 6c) connected to the distribution board interiors 1 and 2a shown in FIG. 6 reacts from the flashover voltage of 230V and the impulse discharge current as shown in the graphs of FIGS. Lightning arrester capable of discharging up to 20 KA (rated 1.2 / 50 μs or rated 8/20 μs) and lightning arrester rated 10/350 μs capable of reacting from a flashover voltage of 1.4 KV and discharging to an impulse discharge current of 40 KA A plurality of lightning protection elements 6a, 6b, and 6c referred to as class 1, class 2, and class 3. It can also be applied to a type of box in which either class 2 or class 3 is received in a box and 50 KA of class 1 and 40 KA of class 2 are inserted.

  As shown in FIG. 7, a plurality of surge current avoidance elements 6a, 6b, and 6c having different response start voltages are combined with an AC power supply circuit of a communication network, a television cable, a sensor system, or a wireless cable including the optical communication network 10. Mounting, grounding pole G of horizontal strata and vertical strata with different grounding resistance and horizontal grounding cable of the ground cable of each floor and vertical grounding cable of each floor are connected by near-by grounding, and cables for communication, antenna and sensor DC circuits One or a plurality of surge current avoidance elements 6a, 6b, 6c having different response start voltages are attached, and the negative poles of the surge current avoidance elements 6a, 6b, 6c are connected to the negative pole of the surge current avoidance circuit 7 of the power circuit 1. Current sensor of counter circuit 2 to equipotential bonding cable Mounting, mounting the discharge circuit switch and counter display unit 2a, destroying data stored by discharging the surge current to the storage device 3.

As shown in FIG. 7, a network communication device and a server rack 11 for storing servers are arranged with one main system and two subsystems, and at least three storage devices 3 are also installed in the server rack 11. computer, and the first storage device connected to the communication cable drawn from the outside, to communicate via the hub, further, the second storage device and a third storage device is disposed, to the server 1 When a virus enters, one of the three storage devices 3 is turned off, one of the remaining two devices is turned on, and the network cable of one storage device into which the virus has entered or By discharging excessive current to the storage device main unit, data that has entered the main server is isolated, and switching the sub server does not affect normal communication. To build the beam. As a result, it is possible to carefully analyze the virus intrusion route and the contents of the virus software without affecting normal communication. Therefore, in the past, when a virus invades, it is impossible to determine how long it will spread, and the date and time of contamination cannot be specified, but this can be solved. Previously, a countermeasure was taken to delete all stored data, so deleting the stored data after a virus leaked outside through the network did not provide a drastic solution. it can. By discharging excess current, such as surge current, and discharging the network in an isolated state, all viruses can be eliminated in an isolated state, for example, even if a subcircuit is attacked Since normal operation can be performed in the following sub-circuit, data communication is not affected. In other words, by rotating and using three data circuits and one server main circuit and two sub-circuits in total, a storage device that is powered on for the stored data while destroying only the virus Back up to

  Further, the stored data is destroyed by discharging a surge current having a voltage lower than the response start voltage between the lightning protection elements 6a, 6b, 6c arranged between the cables connected to the network hub. It is also possible to branch a plurality of connectors from the surge current discharge circuit 7 and connect a storage device to each of these connectors to discharge, and simultaneously erase the stored data of the plurality of storage devices.
