Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a testing device for an electric bicycle anti-theft system. Background Art

[0002] Electric bicycles, as an environmentally friendly and convenient means of transportation, have gained widespread use in cities. However, as their popularity grows, so too has the problem of electric bicycle theft. Electric bicycle theft has become a common and frequent crime, not only causing inconvenience to owners but also posing a threat to public security. While existing technologies offer a certain degree of protection for the exterior of electric bicycles, they neglect the security system's ability to identify and defend against illegal signals, making them susceptible to widespread and potentially vulnerable attacks. Therefore, we propose a test device for electric bicycle anti-theft systems. Utility Model Content

[0003] In order to make up for the above deficiencies, the present application provides an electric bicycle anti-theft system testing device, which aims to improve the problem of illegal signal identification testing.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0016] See also Figure 1-2The present application provides an electric bicycle anti-theft system test device, including a replay test device 10, wherein a signal acquisition unit 110 is provided in the replay test device 10. The signal acquisition unit 110 is the basis of the entire remote control system, which is responsible for capturing the signal from the remote control 30. The signal acquisition unit 110 is electrically connected to a signal judgment unit 120, and the signal judgment unit 120 is electrically connected to a signal replay unit 130 and a signal tampering unit 140. It also includes an electric bicycle body 20 and a remote control 30. The remote control 30 transmits a signal to the electric bicycle body 20. Specifically, when performing a signal test, the remote control 30 is used to transmit a signal to the electric bicycle body 20, and then the signal transmitted by the remote control 30 is intercepted by the signal acquisition unit 110, so that the signal is transmitted to the signal judgment unit 120. It should be noted that the core function of the signal judgment unit 120 is to detect the captured remote control signal. It uses a specific algorithm to identify the characteristics of the signal, such as frequency, amplitude and pulse width, and judges the similarity of multiple signals to identify repeated or similar remote control commands, and then judges the intercepted remote control signal. The remote control signal is then transmitted to the signal replay unit 130, so that the signal replay unit 130 replays the previously captured or processed signal to confirm whether the electric bicycle body 20 responds. This process is mainly used to verify the integrity and validity of the signal to ensure that the signal is not tampered with or damaged during transmission. After determining that the electric bicycle body 20 responds, the signal judgment unit 120 transmits the signal to the signal tampering unit 140, so that the signal tampering unit 140 tampered with the signal, and then sends a signal to the electric bicycle body 20, thereby confirming whether the electric bicycle body 20 responds to complete the test purpose.

[0017] See Figure 2 The signal acquisition unit 110 includes several signal receivers 1110, which intercept the signals transmitted by the remote control 30. When set, the several signal receivers 1110 are used to capture electromagnetic wave signals transmitted in multiple frequency bands. The signal receivers 1110 are connected to the mainboard of the signal acquisition unit 110.

[0018] See Figure 2 The signal acquisition unit 110 also includes an A / D converter 1120, which converts the analog signal received by the signal receiver 1110 into a digital signal. Specifically, an interface is provided on the main board of the signal acquisition unit 110, which is connected to the signal judgment unit 120 through the interface to transmit the intercepted signal to the signal judgment unit 120, and the signal judgment unit 120 determines whether the intercepted signal is the remote control signal transmitted by the remote controller 30.

[0019] See Figure 2The signal replay unit 130 includes a first D / A converter 1310 and a first signal transmitter 1320. The first D / A converter 1310 converts the digital signal transmitted by the signal judgment unit 120 into an analog signal, and the first signal transmitter 1320 transmits the analog signal to the electric bicycle body 20. In the specific setting, after the signal judgment unit 120 confirms that the intercepted signal is a remote control signal, it transmits the signal to the signal replay unit 130. The signal replay unit 130 converts the digital signal into a remote control signal through the first D / A converter 1310, and transmits the remote control signal to the electric bicycle body 20 through the first signal transmitter 1320 to confirm whether the electric bicycle body 20 responds.

[0020] See Figure 2 The signal tampering unit 140 includes a second D / A converter 1410 and a second signal transmitter 1420. The second D / A converter 1410 converts the digital signal transmitted by the signal judgment unit 120 into an analog signal. The second signal transmitter 1420 transmits the analog signal modified by the signal tampering unit 140 to the electric bicycle body 20. Specifically, after the electric bicycle body 20 receives the remote control signal transmitted by the signal replay unit 130 and confirms that there is a response, the recorded signal is transmitted to the signal tampering unit 140. After the signal tampering unit 140 tampers with the signal, the digital signal is converted into a remote control signal through the second D / A converter 1410, and the remote control signal is transmitted to the electric bicycle body 20 through the second signal transmitter 1420, so that whether the electric bicycle body 20 responds can be observed to complete the test.

[0021] When using this electric bicycle anti-theft system test device: first turn on the device, set it to recording mode, and repeatedly press any function button of the remote control 30 at least 3 times. At this time, the device signal acquisition unit 110 will intercept the signal sent by the key each time and demodulate it into a digital signal, and then pass the intercepted signal to the signal judgment unit 120 to judge the similarity of the signals. If the similarity is high, the next step of signal replay is performed, and the recorded signal is directly replayed through the signal replay unit 130 to observe whether the electric bicycle body 20 responds. After confirming that the electric bicycle body 20 responds, tamper replay is performed, and the recorded signal is passed to the signal tampering unit 140. The signal tampering power supply is tampered with and replayed according to the rules that have been mastered to observe whether the electric bicycle responds, and the test is completed.

[0022] It should be noted that the specific model and specifications of the remote control 30 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0023] The power supply and principle of the remote controller 30 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
