Description

  The present invention relates to a wireless signal scan detection device capable of adjusting an optimal reception position of the wireless Internet and preventing voyeurism and eavesdropping.

  Today, our lives are almost inseparable from the world of wireless signals, and various radio signals are constantly present around us, including the most universally used mobile phones and radios. And even the Internet has been upgraded from the wired world to the wireless domain, which has always played a big role for those who are in different places because of their work needs, but radio signals are always building It is obstructed by the object, affected by the direction of the transmitting station, the received signal is deteriorated, causing inconvenience to the user. Therefore, in order to obtain better reception quality, the user purchases a wireless signal detector having a detectable network bandwidth of 2.4 G to 2.483 GHz, and the signal receives the optimum reception quality in any direction. It must detect if possible and avoid interrupting the network connection due to signal continuity.

  Furthermore, some detection electronic products such as micro cameras and wiretapping devices may be illegally applied to malicious persons, and the privacy of others is damaged. In order to protect the privacy while going out, many people have purchased more wireless detectors for preventing voyeurism and eavesdropping (the detection range is approximately 50 M to 2.5 GHz).

  The above-mentioned two wireless signal detectors are mainly used to determine the direction of the signal source by detecting the strength of the received signal, in order to prevent the optimal wireless Internet direction and voyeurism and wiretapping. It is necessary to purchase two types of wireless detection devices, and the purchase cost of the user becomes very high, and it is also inconvenient for the user to carry two types of wireless devices at the same time.

  The inventor feels imperfection about the above-mentioned lack of conventional signal detection devices, aiming to research and overcome, and using the experience accumulated in this industry for many years, adjust the optimal receiving position of the wireless Internet Developed a wireless signal scan detection device that can prevent voyeurism and eavesdropping.

  The main object of the present invention is to design a wireless signal scan detection device, adjust the optimal reception position of the wireless Internet, and achieve an effect of preventing voyeurism and eavesdropping.

  In order to achieve the above object, the present invention includes at least a signal processor, a signal detection module, a power supply module, an antenna, a display device, a switching module, a battery, and the like, and detects the strength of the wireless Internet signal using the switching module. Can select whether to detect high-frequency signals in a large range, and control the type of detection signal using the power module, which can adjust the optimal receiving position of the wireless Internet, The wireless signal scan detection device can achieve the effect of preventing eavesdropping.

〔Example〕
In order that the purpose, characteristics, and effects of the present invention can be understood, specific examples are introduced herein, and the present invention is described in detail as follows with reference to the accompanying drawings.

  FIG. 1 is a circuit block diagram of the present invention. As shown in the figure, this wireless signal scan detection device includes at least an antenna 1, a signal detection module 2, a power supply module 3, a switching module 4, a display device 5, a battery 6 and a signal processor 7, of which the antenna 1 is used to receive a radio signal, and the signal detection module 2 includes a main amplifier 21 coupled to the antenna 1, and first and second filters 22 and 23 ( The first filter is connected to a bandpass filter that restricts the passage of 2.4 G to 2.483 GHz, and the main rear amplifier 24 is also connected to the rear end of the first filter 22, and the main rear amplifier 24 is enlarged. The signal is sent to the detection amplifier 25, and the rear end of the second filter 23 is directly connected to the detection amplifier 25. Amplifier 25 sends signals directly to the signal processor 7 or waveform shaping amplifier 26, the waveform shaping amplifier 26 also sends the final signal to the signal processor 7. The power supply module 3 mainly controls and selects the power supply to the main amplifier 21 and the main rear amplifier 24 and continues to supply power to the detection amplifier 25 and the wave rectification amplifier 26. The switching module 4 is mainly used to select the type of detection signal (for example, detection of the optimal signal reception direction of the wireless Internet, or prevention of voyeurism and eavesdropping), and displays from among liquid crystal, light emitting diode, buzzer, etc. One type of display system of the device 5 can be selected. The display device 5 is used to display the intensity of the detected signal, and can be a liquid crystal LCD, a light emitting diode LED, or a buzzer, respectively. The battery 6 is used to provide a normal working power source. The signal processor 7 notifies the power supply target of the power supply module 3 according to the selection of the switching module 4, analyzes the received signal, reflects it on the display device 5, and detects whether the voltage of the battery 6 is stable at any time. The signal processor can also be connected to the threshold reference voltage adjustment buttons 71 and 72 to adjust the sensing intensity and the threshold height.

  The design of the device of the present invention is that when the switching module 4 selects the wireless network (WIFI) detection, the signal processor 7 connects the power supply module 3 to the main amplifier 21, the first filter 22, and the main rear amplifier 24. Notifying the power supply, setting the signal detection range between 2.4G and 2.483GHz, passing through the detection amplifier 25 and the rectifying amplifier 26, sending the data and signal intensity level to the signal processor 7 and its reference potential, and collating them, The obtained result is immediately reflected in the display module 5, and since the detection distance of the wireless Internet signal is relatively long, the received signal is relatively weak. Further clarify.

  When the switching module 4 selects the detection of the abnormal signal (SPY), the signal processor 7 is notified of the power supply to the main amplifier 21 and the second filter 22, and the detection range is approximately 50 M to 2.5 GHz. The signal is sent to the signal processor 7 and its reference potential through the amplifier 25 and collated, and the obtained result is immediately reflected in the display module 5, and the detection signal necessary for preventing voyeurism and eavesdropping is short-range. If the received signal is relatively strong, the threshold reference voltage adjustment button 71 lowers the sensing distance, and the device further reveals only the response status of the signal in the neighborhood. This achieves the effects of optimal reception position adjustment, voyeurism and wiretapping prevention on the wireless Internet.
