Description

Technical Field

[0001] This invention relates to the field of signal transmission, and more particularly to a device for optimizing primary frequency modulation signal transmission. Background Technology

[0002] Frequency deviation is dynamically adjusted to control the active power output and keep the system frequency within a safe threshold. Signal transmission is a key component of the primary frequency modulation system, and its transmission delay, anti-interference capability, and synchronization accuracy directly determine the effectiveness and timeliness of the frequency modulation response.

[0003] In the existing technology, primary frequency modulation signal transmission has many defects: First, it has weak anti-interference capability. There are strong electromagnetic interference and harmonic pollution problems in the power system field. Traditional transmission lines are easily interfered with, resulting in signal distortion and thus causing deviation in the execution of frequency modulation commands. Second, the transmission delay is large. Traditional optical fiber or cable transmission has a high delay, resulting in lag in frequency modulation action.

The clock of the signal acquisition and the receiving end are not synchronized, which easily leads to phase deviation and affects the frequency modulation adjustment accuracy.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a frequency modulation signal transmission optimization device provided by the present invention; Figure 2 for Figure 1 The diagram shows the structure of the signal input interface. Figure 3 for Figure 2 The diagram shows a cross-sectional view of the signal input interface. Figure 4 for Figure 3 The enlarged schematic diagram of part A is shown. A primary frequency modulation signal transmission optimization device includes: a chassis, a battery module, a dual-redundant power supply, a metal shielding shell, an anti-disconnection interface assembly, a cooling fan, an intelligent monitoring feedback module, a signal acquisition module, a signal preprocessing module, an optimized transmission module, a signal receiving module, and a synchronization calibration module; The output terminal of the signal preprocessing module is located at the output terminal of the signal acquisition module, the output terminal of the optimized transmission module is located at the input terminal of the signal preprocessing module, the output terminal of the signal receiving module is located at the input terminal of the optimized transmission module, and the output terminal of the synchronization calibration module is located at the input terminal of the signal receiving module.

[0021] The battery module is used to power the electronic components installed on the chassis, and is powered by dual redundant power supplies.

[0022] Signal acquisition module: It adopts a high-precision synchronous sampling chip, model AD7606, with a sampling period of ≤100ms, which meets the requirements of DL / T1870-2018 standard. It is used to acquire power grid frequency signals, unit output signals and frequency modulation command signals, convert analog signals into digital signals and output them to the signal preprocessing module. Optimized transmission module: It adopts a wired transmission structure, and the wired transmission unit uses the industrial Ethernet chip DP83848, which supports Gigabit Ethernet transmission; the module has a built-in delay compensation algorithm, which dynamically adjusts the signal transmission timing based on the transmission distance to reduce transmission delay; Signal receiving module: The corresponding signal receiving module decodes and corrects the received signal through the decoding unit. The decoding unit is adapted to the error correction coding unit of the preprocessing module to ensure the accuracy of signal restoration. Synchronization calibration module: integrates a Beidou clock synchronization unit, which controls the clock deviation between the signal acquisition end and the receiving end to within 20ms, so as to realize synchronous signal transmission; Power supply module: It adopts dual redundant power supply with an input voltage range of AC220V±10% and output DC voltages of 24V and 5V, which power each module respectively to ensure uninterrupted operation of the device.

[0023] The chassis uses a metal shielded shell, and the inside of the shell is covered with electromagnetic shielding material to reduce the impact of external electromagnetic interference on the internal modules. The surface of the chassis is equipped with heat dissipation holes and a cooling fan. The cooling fan is electrically connected to the intelligent monitoring and feedback module and automatically adjusts its speed according to the internal temperature of the chassis.

[0024] The intelligent monitoring and feedback module includes an audible and visual alarm unit and a host computer feedback interface.

[0025] The anti-detachment interface component includes a signal output interface 1, a signal input interface 2, and a limiting device 3. The limiting device 3 is disposed at one end of the output interface 1, and the signal input interface 2 is disposed at one end of the limiting device 3.

[0026] The limiting device 3 includes a limiting sleeve 31 and a mounting sleeve 32. One end of the limiting sleeve 31 is rotatably connected to one end of the signal output interface 1, and the mounting sleeve 32 is threadedly connected to the inside of the limiting sleeve 31.

[0027] The limiting sleeve 31 is a threaded sleeve, and the surface of the mounting sleeve 32 is provided with a thread that matches the limiting sleeve 31. After the limiting sleeve 31 is installed on the surface of the mounting sleeve 32, it limits the connection between the signal output interface 1 and the signal input interface 2, thereby preventing the connector from falling off.

[0028] The limiting device 3 also includes two limiting grooves 33, two limiting blocks 34 and a connecting sleeve 35. The two limiting grooves 33 are both opened inside the mounting sleeve 32. The two limiting blocks 34 are slidably connected to the inside of the two limiting grooves 33 respectively. The mounting sleeve 32 is fixedly connected to the surface of the limiting blocks 34.

[0029] One side of each of the two limiting blocks 34 is fixedly connected to the surface of the connecting sleeve 35, which is used to position the connecting sleeve 35 and increase the stability of the connecting sleeve 35 when it moves.

[0030] The limiting device 3 also includes two elastic elements 36, which are respectively fixedly installed inside the two limiting grooves 33.

[0031] The elastic element 36 is used to squeeze the limiting block 34 after it moves to a certain position inside the limiting groove 33, so that the limiting sleeve 31 moves to the appropriate position. The elastic element 36 then applies pressure to the limiting block 34, thereby applying pressure to the limiting sleeve 31 and increasing the limiting effect of the limiting sleeve 31.

[0032] The elastic element 36 can be a rubber block, a spring, a spring telescopic rod, etc.

[0033] The working principle of the frequency modulation signal transmission optimization device provided by this invention is as follows: In use, when connecting signal output interface 1 and signal input interface 2, the connecting sleeve 35 at one end of output interface 1 is inserted into the interior of mounting sleeve 32, while the two limiting blocks 34 are respectively inside the two limiting grooves 33. At the same time, the limiting sleeve 31 is rotated to one side, so that the limiting sleeve 31 moves to one side on the surface of mounting sleeve 32, thereby causing the connecting sleeve 35 to move to one side inside mounting sleeve 32. When the limiting sleeve 31 moves to the appropriate position, the connection between signal output interface 1 and signal input interface 2 is completed.

[0034] When disassembling the signal output interface 1, the signal output interface 1 can be removed by rotating the limiting sleeve 31 in the opposite direction to separate the limiting sleeve 31 from the mounting sleeve 32.

Through a signal acquisition module, a signal preprocessing module, an optimized transmission module, a signal receiving module, and a synchronization calibration module, the device transmits signals, thereby effectively improving the power signal transmission speed, reducing signal delay to 80ms, significantly enhancing anti-interference capabilities, effectively resisting electromagnetic interference and harmonic pollution in the power field, reducing the signal error rate by more than 40%, ensuring the integrity of signal transmission, and through a clock device, ensuring that the clock deviation between the signal transmitter and receiver is within 20ms.

[0039] A sealing block 6 is fixedly connected to one side of the sealing plate 5, and a fixing device 7 is provided inside the mounting sleeve 32. The fixing device 7 is used to limit the position between the sealing block 6 and the sealing block 6.

[0040] The fixing device 7 can also be a magnet, a buckle, a lock, etc., used to limit the movement between the sealing block 6 and the sealing block 6.

[0041] The fixing device 7 includes a fixing groove 71 and a fixing ring 72. The fixing groove 71 is formed inside the mounting sleeve 32, and the fixing ring 72 is disposed inside the fixing groove 71.

[0042] The inner wall surface of the fixing ring 72 is fixedly installed on the surface of the sealing block 6.

[0043] The fixing ring 72 is a sealing ring and is semi-circular. It is used to limit the sealing block 6 while increasing the sealing effect of the sealing block 6 after the fixing ring 72 enters the interior of the fixing groove 71.

[0044] The working principle of the frequency modulation signal transmission optimization device provided by this invention is as follows: When in use, when the signal input interface 2 is not in use, the sealing block 6 is inserted into the inside of the mounting sleeve 32, and the fixing ring 72 is inserted into the inside of the fixing groove 71 to limit the sealing block 6.

[0045] When using the signal input interface 2, the sealing block 6 is moved to one side by moving the sealing plate 5 to one side, and then separated from the sealing plate 5.
