Description

Technical Field

[0001] This invention relates to the field of anti-interference technology for the Internet of Things (IoT), specifically to an anti-interference device based on IoT technology. Background Technology

[0002] The Internet of Things (IoT) refers to the use of various information sensors, radio frequency identification (RFID) technology, global positioning systems (GPS), infrared sensors, laser scanners, and other devices and technologies to collect real-time information on any object or process that needs to be monitored, connected, or interacted with. This information includes sound, light, heat, electricity, mechanics, chemistry, biology, location, and other necessary data. Through various possible network access methods, it enables ubiquitous connectivity between things and between things and people, achieving intelligent perception, identification, and management of objects and processes. The IoT is an information carrier based on the Internet, traditional telecommunications networks, etc., which allows all ordinary physical objects that can be independently addressed to form an interconnected network.

[0003] Application number CN202222186454.5 discloses an anti-interference device based on Internet of Things (IoT) technology, including a housing. A cover plate is slidably and sealed to the upper end of the housing. An anti-electromagnetic wire mesh is fixedly connected to the bottom end of the cover plate. A rectangular movable hole is opened through the upper right side of the cover plate. An anti-electromagnetic wire mesh is fixedly connected to the inner wall of the housing. The right side of a dehumidifying plate is slidably and sealed to the cover plate through the movable hole. The right side of a dehumidifying plate is slidably and sealed to the left side of the dehumidifying plate. The cover plate is slidably and sealed to the left side of the dehumidifying plate. A rack and pinion are fixedly connected to the front ends of the dehumidifying plates, respectively. Gears mesh on the left and right sides of the racks, respectively, and the gears are rotatably connected to the upper side of the inner front wall of the housing. In use, the combined action of the dehumidifying plates, racks, and gears causes the dehumidifying plate to rise when the dehumidifying plate is pressed down, allowing for alternating use of the dehumidifying plates to maintain a dry environment inside the device.

[0004] During the current use of the device, interference signals emitted by internal or external interference sources can affect the internal signal transmission and external signal exchange, resulting in the inability to receive the interfered signals and transmit the correct commands, which is very inconvenient. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-interference device based on Internet of Things technology to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: an anti-interference device based on Internet of Things (IoT) technology, comprising a device housing, a heat dissipation hole on the top of the device housing, a heat dissipation rod at the bottom of the heat dissipation hole, a ventilation groove on the inner side of the device housing, an anti-interference zone inside the device housing, a heat dissipation device on the side of the anti-interference zone, the heat dissipation device being disposed on the side of the ventilation groove, a plug plate fixedly connected to the bottom of the device housing, the plug plate being movably connected to the anti-interference zone, and an anti-interference device being disposed inside the anti-interference zone.

[0007] Furthermore, a heat dissipation rod is installed at the location of the heat dissipation hole, and a cooling device is installed at the bottom of the heat dissipation rod. The heat dissipation rod is fixedly connected to the cooling device, and its top passes through the cooling device. A heat-absorbing shell is installed at the bottom of the cooling device, and the heat dissipation rod is fixedly connected to the heat-absorbing shell. The cooling device is filled with cooling water. When the device is working, it can absorb part of the heat inside the device through the heat-absorbing shell, and then transfer the heat outward through the heat dissipation rod fixedly connected to the heat-absorbing shell. During the heat transfer process, the heat dissipation rod comes into contact with the cooling water inside the cooling device, and the cooling water absorbs part of the heat, and then the heat is discharged through the heat dissipation hole, so that the inside of the device will not overheat and the service life of the device will be extended. At the same time, the heat dissipation device installed on the side of the anti-interference area can dissipate heat from the inside of the device after the device is started, and can also blow out the dust inside the device, so as to prevent the accumulation of dust inside the device and affect the performance of the internal electronic components.

[0008] Furthermore, the device housing is made of a low-resistance metal material, the heat-absorbing housing and heat sink are heat-absorbing materials, and the insert plate is made of a low-resistance elastic material. The device housing can isolate some external signals and play a certain role in preventing interference to the transmission of signals inside the device. The insert plate can absorb some heat after the device is started and expand after absorbing heat, which improves the coverage of the bottom of the anti-interference zone. At the same time, after the insert plate expands, it will be tightly attached to the bottom of the anti-interference zone, which improves the sealing performance of the device.

[0009] Furthermore, the anti-interference device includes a transmitting unit, an election unit, a receiving unit, a judgment unit, and an anti-interference unit.

[0010] Furthermore, the transmitting unit is used to transmit dedicated frequency band signals to realize information exchange based on the Internet of Things.

[0011] Furthermore, the election unit is used to determine the master device and slave device in the Internet of Things system, and to determine the information sender and information receiver in information exchange.

[0012] Furthermore, the receiving unit is used to receive the set interference control rules and the signal information sent by the master device and the slave device. It is equipped with a demodulator, which can recover the message from the modulated signal carrying the message.

[0013] Furthermore, the judgment unit is used to determine whether there is interference between the master device and the slave device or between each slave device based on the signal information, and can determine the frequency of the interference signal after interference, and collect the interference signal.

[0014] Furthermore, the anti-interference unit is used to coordinate the interfering devices according to interference control rules when interference is present. The anti-interference unit is internally equipped with a modulation device, a mixer, a bandpass filter, and a low-noise amplifier. The modulator can inject a carrier wave into the initial signal and use this signal to modulate the carrier wave in order to convert the initial signal into a radio wave signal suitable for transmission. The function of modulation is to place the message into a message carrier for easy transmission or processing. The mixer is located after the low-noise amplifier and directly processes the radio frequency signal amplified by the low-noise amplifier. The bandpass filter is a device that allows waves of a specific frequency band to pass through while blocking other frequency bands. The low-noise amplifier can amplify weak signals and reduce the signal-to-noise ratio.

[0015] When transmitting signals, the device first amplifies the signal using a low-noise amplifier, simultaneously reducing the signal-to-noise ratio of weak signals during amplification. The signal then passes through a bandpass filter, which attenuates frequency components within a defined frequency range to extremely low levels, filtering out some external interference signals and providing a certain degree of anti-interference capability. Next, a mixer converts the transmitted signal and the local oscillator signal to the same frequency. The two signals are then added or multiplied to obtain an intermediate frequency (IF) signal. The judgment unit determines whether interference exists between the master and slave devices or among slave devices based on the signal information. If interference is detected, the frequency of the interfering signal is determined and collected. The interfering signal is then converted to the IF signal to obtain a new signal with a different frequency than the interfering signal, enabling faster, interference-free propagation. A modulation device processes the signal source information and adds it to the carrier wave, transforming it into a form suitable for channel transmission. Finally, the signal is transmitted through the transmitting unit, reducing the probability of interference during transmission and improving anti-interference capability.

[0016] While transmitting the signal, the judgment unit also transmits the interference signal through the transmitting unit. After the receiver receives the two signals, it performs demodulation once through the demodulation device, compares the interference signal to demodulate the intermediate frequency signal, and extracts the interference signal to obtain the mixed intermediate frequency signal. Then, it performs secondary demodulation through the demodulation device to extract the local oscillator signal of the modulation device, thereby obtaining the original signal and thus improving the anti-interference capability of the device.

[0017] Beneficial effects:

[0018] 1. This anti-interference device based on IoT technology can absorb some of the heat inside the device through the heat-absorbing shell when the device is working. Then, the heat is transferred to the outside through the heat dissipation rod fixedly connected to the heat-absorbing shell. During the heat transfer process, the heat dissipation rod comes into contact with the cooling water inside the cooling device. The cooling water absorbs some of the heat and then discharges some of the heat through the heat dissipation holes, so that the inside of the device will not overheat and the service life of the device will be extended. At the same time, the heat dissipation device on the side of the anti-interference area can dissipate heat from the inside of the device after the device is started, and also blow out the dust inside the device to prevent the accumulation of dust inside the device from affecting the performance of the internal electronic components.

[0019] 2. This anti-interference device based on IoT technology first amplifies the signal using a low-noise amplifier, simultaneously reducing the signal-to-noise ratio of weak signals during amplification. The signal is then passed through a bandpass filter, which attenuates frequency components within a set frequency range to extremely low levels, effectively filtering out some external interference signals and providing a certain degree of anti-interference capability. Next, a mixer converts the frequency of the transmitted signal and the local oscillator signal, converting them to the same frequency. Finally, the two signals are added or multiplied to mix them. By obtaining an intermediate frequency (IF) signal, the judgment unit determines whether there is interference between the master device and the slave device, or between the slave devices, based on the signal information. After interference is detected, the frequency of the interference signal is determined and collected. The interference signal and the IF signal are then frequency-converted to obtain a new signal. This new signal has a different frequency than the interference signal, enabling faster and interference-free propagation. The signal source information is then processed by a modulation device and added to the carrier wave to make it suitable for channel transmission. Finally, the signal is transmitted by the transmission unit, reducing the probability of interference during signal transmission and improving anti-interference capability.

[0020] 3. This anti-interference device based on Internet of Things technology transmits signals while simultaneously transmitting interference signals through the judgment unit. After the receiver receives both signals, it performs demodulation once through a demodulation device, compares the interference signals to demodulate the intermediate frequency signal, and extracts the interference signals to obtain the mixed intermediate frequency signal. Then, it performs secondary demodulation through a demodulation device to extract the local oscillator signal of the modulation device, thereby obtaining the original signal and thus improving the device's anti-interference capability.

[0034] The judgment unit is used to determine whether there is interference between the master device and the slave device or between the slave devices based on the signal information. After interference occurs, it can determine the frequency of the interference signal and collect the interference signal.

[0035] The anti-interference unit is used to coordinate the devices involved in interference according to interference control rules when interference is present. The anti-interference unit is equipped with a modulation device, a mixer, a bandpass filter, and a low-noise amplifier.

The low-noise amplifier can amplify weak signals and reduce the signal-to-noise ratio.

[0036] When transmitting signals, the device first amplifies the signal using a low-noise amplifier, simultaneously reducing the signal-to-noise ratio of weak signals during amplification. The signal then passes through a bandpass filter, which attenuates frequency components within a defined frequency range to extremely low levels, filtering out some external interference signals and providing a certain degree of anti-interference capability. Next, a mixer converts the transmitted signal and the local oscillator signal to the same frequency. The two signals are then added or multiplied to obtain an intermediate frequency (IF) signal. The judgment unit determines whether interference exists between the master and slave devices or among slave devices based on the signal information. If interference is detected, the frequency of the interfering signal is determined and collected. The interfering signal is then converted to the IF signal to obtain a new signal with a different frequency than the interfering signal, enabling faster, interference-free propagation. A modulation device processes the signal source information and adds it to the carrier wave, transforming it into a form suitable for channel transmission. Finally, the signal is transmitted through the transmitting unit, reducing the probability of interference during transmission and improving anti-interference capability.

[0037] While transmitting the signal, the judgment unit also transmits the interference signal through the transmitting unit. After the receiver receives the two signals, it performs demodulation once through the demodulation device, compares the interference signal to demodulate the intermediate frequency signal, and extracts the interference signal to obtain the mixed intermediate frequency signal. Then, it performs secondary demodulation through the demodulation device to extract the local oscillator signal of the modulation device, thereby obtaining the original signal and thus improving the anti-interference capability of the device.
