Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage power grids, and more specifically to a perimeter protection high-voltage power grid device based on strike electricity. Background Art

[0002] The perimeter defense high-voltage power grid device is an AC device installed at the perimeter of the protection area of ​​specific high-security places such as prisons and detention centers. Its live network can strike the objects that touch the network by controlling the strike electricity. It is the only device with strike effect and deterrence. It is the last line of defense for specific high-security places such as prisons and detention centers. The high-voltage power grid is generally fixed on the wall at different angles. The number of high-voltage wires is 5 wires with a spacing of 20 cm. A high-voltage generator (referred to as a high-voltage control box) is equipped for each 100-150m section. The output voltage (effective value) between the equipment and the ground wire should be in the range of 4000V to 6000V, and the output voltage (effective value) between adjacent live metal wires should be in the range of 8000V to 12000V. When someone touches the high-voltage wire network, high-voltage discharge can be generated to the human body, making it unable to move, thereby preventing criminals from illegally crossing the border.

[0003] At present, the perimeter protection high-voltage power grid equipment used in prisons adopts the common high-voltage transformer boosting technology, which does not have the ability to output sustainable striking power when the network is touched or short-circuited. If someone illegally crosses the boundary and puts iron wire or other conductors on the high-voltage network, the high-voltage network voltage will be short-circuited and lose its electric striking ability. Long-term short circuit will also cause the transformer of the high-voltage control box to burn out.

[0004] In recent years, there have been many cases of prisoners escaping successfully due to short circuits in the perimeter power grid. Therefore, there is an urgent need for a perimeter defense high-voltage power grid device that can control the amount of electricity struck.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a perimeter protection high-voltage power grid device based on strike electricity is provided, in order to achieve a more practical purpose. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a perimeter protection high-voltage power grid device based on strike electricity, which can realize high-voltage electricity protection for protective places, and has a fast response speed and a long action time of the high-voltage power grid, thus solving the drawback of high-voltage network voltage short circuit and effectively improving the safety of specific places such as prisons.

[0024] Furthermore, in the control software of the low-voltage power grid control host, when the set strike power mC is adjusted:

[0025] The larger the strike power value is, the shorter the strike interval is and the longer the strike duration is.

[0048] Embodiment 1:

[0049] See also Figure 1 - Figure 6 A perimeter protection high-voltage power grid device based on strike electricity includes a low-voltage power grid control host, a plurality of composite high-voltage boxes and a high-voltage metal mesh. The low-voltage power grid control host, a plurality of composite high-voltage boxes and a high-voltage metal mesh constitute a high-voltage power grid system. The entire high-voltage power grid system can realize high-voltage electrical protection for the protection site, and has a fast reaction speed and a long action time of the high-voltage power grid, which solves the disadvantage of high-voltage network voltage short circuit and effectively improves the safety of specific places such as prisons.

[0050] A high-voltage control extension and two high-voltage control boxes are arranged inside the composite high-voltage box, and the two high-voltage control boxes are arranged in opposite phases. The first output port of the high-voltage control extension is provided with a power supply line, and the high-voltage control extension is connected to the power supply control port of the high-voltage control box through the power supply line. The second output port of the high-voltage control extension is provided with a horizontal number conversion line, and the high-voltage control extension is connected to the signal port of the high-voltage control box through the horizontal number conversion line;

[0051] The power supply port of the low-voltage power grid control host is connected to the extension power supply line, and the low-voltage power grid control host is respectively connected to the corresponding composite high-voltage box through the extension power supply line, and is connected to the high-voltage control extension. The signal port of the low-voltage power grid control host is connected to the CAN control bus, and the low-voltage power grid control host is connected to a plurality of sentry tower alarm extensions through the CAN control bus. The sentry tower alarm extensions are arranged in a one-to-one correspondence with the composite high-voltage box, and the sentry tower alarm extension is connected to the high-voltage control extension inside the composite high-voltage box through the CAN control bus.

[0052] The high-voltage metal mesh is divided into several defense zones, and two groups of high-voltage insulating wires are arranged between the high-voltage metal mesh in each defense zone and the corresponding composite high-voltage box, and the two high-voltage control boxes are respectively connected to the high-voltage metal mesh in the defense zone through a group of high-voltage insulating wires;

[0053] Each defense zone of the high-voltage metal mesh is independently provided with a warning light, and the warning light is connected to a solar power supply device.

[0054] See also Figure 1 and Figure 2 Specifically, the number of defense zones of the high-voltage metal mesh is no more than sixteen, and each defense zone forms a bus extension with the corresponding composite high-voltage box and guardhouse alarm extension.

[0055] Each extension and its matching high-voltage control box form an independent system. The bus-based extension uses a high-reliability single-chip microcomputer as the control component, which can independently control the operation of a section of high-voltage power grid. It uses an A / D converter to collect the voltage and current on the high-voltage power grid, and makes judgments on normal, grid-connected and other states based on the measured data, and transmits the measured data and working status to the industrial computer of the main cabinet through the CAN bus.

[0056] Specifically, the power grid structure arranged in the bus-system extension is a differential pressure power grid;

[0057] Two high-voltage control boxes with opposite phases are arranged in the composite high-voltage box inside the differential pressure power grid.

[0058] Each bus extension can select its own extension address according to the DIP switch in the extension. When the extension address matches the address called by the low-voltage power grid control host, data communication can be carried out to complete data transmission and control.

[0059] See also Figure 1 and Figure 3 Specifically, the low-voltage power grid control host receives the data signal of the composite high-voltage box and the alarm signal of the sentry tower alarm extension, and displays it on the computer screen.

[0060] The low-voltage power grid control host uses an industrial computer as the control center. Through the instructions of the power grid management software, the instructions are transmitted to the corresponding high-voltage control extension through the CAN bus interface, and the measurement data and status of each bus extension are collected and displayed on the computer screen. The data, status and electronic map, if there is an alarm, can be displayed on the screen and reported by voice.

[0061] The specific functions of the low-voltage power grid control host include:

[0062] (1) Provide independent isolated voltage signals to the high voltage control box;

[0063] (2) Receive the detection signal transmitted by the front-end extension and decide whether to alarm. If an alarm occurs, it will alarm in sections in the form of sound and light and voice reading;

[0064] (3) Sending control strike instructions to the extension via the CAN bus;

[0065] (4) Display the real-time voltage and current values ​​of each extension;

[0066] (5) Provide multi-way switch signals to link with other devices;

[0067] (6) Display electronic map and alarm log query;

[0068] (7) Record the deployment and withdrawal time of the high-voltage power grid;

[0069] (8) Patrol and monitor the operation of each defense zone at any time;

[0070] (9) Share power grid information with computers in the network by connecting computers to the local area network;

[0071] (10) Connect several extensions with voice announcement and police reporting positions through CAN bus;

[0072] (11) The power supply and data of each defense zone can be cut off and connected to facilitate system inspection and maintenance;

[0073] (12) Reduce voltage control in rainy and foggy days.

[0074] See also Figure 1 and Figure 4 , specifically, the composite high-voltage box provides an AC voltage of 10000V between the live wires of the high-voltage metal mesh or the live wires;

[0075] The composite high-voltage box provides an AC voltage of 5000V between the live wire or the ground wire of the high-voltage metal mesh.

[0076] The specific functions of the composite high-voltage box include:

[0077] (1) Transmit the detection signal of the high-voltage power grid front end to the high-voltage control extension through a 3*0.5 cable;

[0078] (2) Convert the analog signal sent from the high-voltage control box into digital form, perform digital processing, and transmit it to the low-voltage power grid control host through the bus;

[0079] (3) Receive instructions from the low-voltage power grid control host and control the high-voltage control box;

[0080] (4) With warning light and siren output interface, 220V or switch quantity optional;

[0081] (5) Can display voltage and current values ​​in real time;

[0082] (6) Provide power supply voltage to the high voltage control box.

[0083] Specifically, a transformer is provided inside the high-voltage control box, and the transformer converts the input voltage of 220V into a high voltage of 5000V.

[0084] The transformer performs voltage transformation operations, and the high-voltage control box has an A / D converter inside. The A / D converter collects the voltage and current on the high-voltage metal mesh in the corresponding defense zone and transmits them back to the low-voltage power grid control host in the control center through the high-voltage control extension. The low-voltage power grid control host in the control center sets parameters for the control extension in the front-end composite high-voltage box, and executes the work after the high-voltage control extension receives the control parameters.

[0085] See also Figure 1 , Figure 5 and Figure 6 Specifically, the strike power range set in the control software of the low-voltage power grid control host is 30-150mC, and the strike interval time range is 300-1000ms.

[0086] The low-voltage power grid control host of the control center directly transmits the set parameters to the single-chip microcomputer of the high-voltage control extension, and the high-voltage control extension determines the current value, voltage value, and strike interval time output by the high-voltage box. When the target triggers the high-voltage metal mesh to touch the mesh, short the mesh, and other actions, the high-voltage box outputs the strike power to the high-voltage metal mesh. No matter how large the current is when the electric shock occurs, or how long the electric shock lasts, as long as the integral of time and current reaches the strike power setting mC, the equipment automatically completes the first strike, and repeats the second, third, and... strikes after the strike interval time (ms) until the person who touches the mesh leaves the power grid.

[0087] In the low voltage grid control host, the strike interval time can be readjusted.

[0088] Embodiment 2:

[0089] Based on the above embodiment 1, further description is given.

[0090] Specifically, the high-voltage control extension uses the dip switch to select the machine number of the bus-based high-voltage control extension. The dip switch is located in the middle of the right side of the bus-based extension control unit: The address setting is shown in the table below:

[0091]

[0092] Among them, high-voltage power grid equipment supports a maximum of 16 partitions.

[0093] Embodiment 3:

[0096] First, make an electronic map and name the file →electronic map.jpg. The file size is not limited. Copy and paste the finished file into the C:\Program Files\High Voltage Power Grid Software directory to replace the original file.

[0097] See also Figure 7 , enter the system and run the "Tianquan Smart Grid Client" executable file.

Enter the dialog box, and each parameter is displayed as the default value. If no modification is required, only the opening or closing of each device can be selected.

[0101] The following are the default values ​​of various parameters:

[0102] a: Extension status: open;

[0103] b: Network contact current: 50mA, high voltage current>50mA, triggering network contact alarm;

[0104] c: Open circuit current: 1mA, high voltage current <1mA, triggering open circuit alarm;

[0109] Each parameter can be modified, and the modification range is provided by the system. You can click the item to be changed with the mouse, and the system will pop up the optional values. Move the mouse to make the selected parameter turn blue, and click the mouse to confirm.

[0112] After entering this interface, click on the opened extension box to adjust it and adjust it to the required electronic map position.

[0113] See also Fig.12 In the map part, the real-time current and voltage values ​​of the four defense zones are displayed, and the alarm information of network contact, network short, network disconnection, communication failure, etc. of each defense zone can be displayed. The alarm information is on the left side of the screen.

[0114] Embodiment 4:

[0115] Based on the above-mentioned Embodiment 1 and Embodiment 2, further description is given.

[0116] See also Fig.13 , in the control software of the low-voltage power grid control host, the strike power set is adjusted.

[0117] The larger the strike power value is, the shorter the strike interval is and the longer the strike duration is.

[0118] The smaller the strike power value is, the longer the strike interval is and the shorter the strike duration is.

[0119] Among them, in the path from one hand to both feet, the specific situation of the time / current area of ​​AC 15Hz to 100Hz is as follows:

[0120]

[0121] The duration of the current is below 200 ms and ventricular fibrillation can only be triggered during the vulnerable period if the relevant threshold is exceeded. Regarding ventricular fibrillation, this figure is related to the effect of the current flowing in the path from the left hand to the feet. For other current paths, the cardiac current coefficient needs to be considered.

[0122] When selecting the output current of the power grid, if the current is selected between 10mA and 500mA, in order to control the power grid strike area within the AC-3 zone, the time requirement should be between 10ms and 10000ms. The C1 curve is the dividing line that causes ventricular fibrillation.

[0123] Once the strike power is determined, the requirements for current I and time t are also determined. The power increases with the increase of current I and time t. Therefore, when the power reaches the value you designed, the current and time must be zero. Otherwise, the power value will continue to increase until it enters the AC-4 zone.

[0124] The most effective way to make the current I=0 is to cut off the power supply. If the power supply is cut off by an AC contactor, there is a problem of cut-off time. The time for the domestic AC contactor to disconnect the contact is 0.32s~0.38s, and the start-up time of the imported AC contactor is 0.30s~0.35s. Theoretically, the output current of the power grid is limited to between 30mA and 200mA.

[0125] According to the above, the maximum output current of the high-voltage power grid device should be between 40mA and 500mA.

[0126] A perimeter protection high-voltage grid device based on strike power has a maximum output current of about 200mA.

[0127] Specifically, a recording system is established in the low-voltage power grid control host, and the information recorded by the recording system includes real-time and historical information, deployment and withdrawal time, and an electronic map of the site.

[0128] Specifically, the low-voltage power grid control host is provided with a plurality of output interfaces and input interfaces, and is connected to a remote control terminal through the output interfaces, the input interfaces and the network;

[0129] The output interface and input interface adopt 485 interface, and the network selects one or more of LAN and CAN bus.

[0130] Through the 485 interface, LAN, and CAN bus, it has powerful network functions, and can upload various technical parameters and alarm conditions in the operation of the high-voltage power grid segmentation alarm system, and transmit them to various competent departments and sentinels within 10KM that need to obtain information. According to future development needs, the system can smoothly transition to hardware expansion and system upgrades.

[0131] The nature of the perimeter high-voltage power grid segmented alarm system determines the requirement for uninterrupted operation of the system. The system adopts technological innovation measures, so that the system can basically achieve non-stop maintenance. The necessary power outage maintenance is also simplified board-level maintenance, which effectively reduces the system's maintenance complexity and maintenance time and cost.

[0132] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
