BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 1 1 is a flow chart of a signal anti-interference method applied to a robot boundary system provided by one embodiment of the present invention;

[0044] Figure 2 It is a structural diagram of a specific example of the present invention;

[0045] Figure 3 、 4 5 are schematic diagrams of the timing structure of the feedback signal of a specific example of the present invention. DETAILED DESCRIPTION

[0046] The present invention will be described in detail below with reference to the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0047] The robot of the present invention can be a lawn mower robot, a sweeping robot, a snow blower, a leaf vacuum, a golf course ball picker, etc. Various robots can automatically walk in the working area and perform corresponding work. In the specific example of the present invention, the robot is a lawn mower as an example for specific description. Accordingly, the working area can be a lawn.

[0048] During the operation of the robot, the working area of ​​the lawn mower is limited by arranging boundary lines. Accordingly, there may be adjacent working areas outside the working area of ​​the robot. In addition, when the robot of the present application is operating in the working area set in the present application, the adjacent working areas synchronously transmit interference signals. The present invention is mainly used to adjust its own transmitting electric pulse signal when the adjacent working areas synchronously transmit interference signals, so that the waveform of the real-time feedback signal received at the predetermined position of the predetermined period is consistent with the waveform formed by the theoretical feedback signal at the predetermined position of the predetermined period; thereby avoiding the interference of the robot of the present application by the interference of the interference signals synchronously transmitted from the adjacent working areas.

[0049] like Figure 1 As shown, the signal anti-interference method applied to the robot boundary system provided by the first embodiment of the present invention includes the following steps:

[0050] S1. Receive the real-time feedback signal and compare it with the theoretical feedback signal generated by the current transmitted electrical pulse signal.

[0051] S2. determining whether a waveform of the real-time feedback signal received at a predetermined position in a predetermined period is consistent with a waveform formed by the theoretical feedback signal at the predetermined position in the predetermined period;

[0052] S3. If not, adjust the transmitted electrical pulse signal so that the waveform of the real-time feedback signal received at the predetermined position of the predetermined period is consistent with the waveform formed by the theoretical feedback signal at the predetermined position of the predetermined period;

[0053] If so, keep the transmitting electric pulse signal unchanged.

[0054] In a specific embodiment of the present invention, a magnetic field induction sensor is provided in a signal generator, the signal generator is used to transmit an electrical pulse signal, and the magnetic field induction sensor is used to receive a feedback signal and feed back the feedback result to the signal generator.

[0055] Combine Figure 2As shown, two adjacent work areas are shown: the work area Q1 of the present invention on the left and the adjacent other work area Q2 on the right. The work area Q1 of the present invention is formed by a signal generator 1 and a boundary line 2 that connects the two ends of the signal generator to form a closed loop. The signal generator 1 is provided with a magnetic field sensing sensor 3. The robot 4 operates within the work area Q1. After the signal generator 1 is started, it transmits an electric pulse signal along the boundary line 2, thereby generating a continuous magnetic field signal near the boundary line 2. The robot 4 senses the magnetic field signal through the sensor on it to maintain operation within the boundary line. However, due to the existence of the adjacent work area Q2, if the signal generator 1' in the work area Q2 transmits the same electric pulse signal as the signal generator 1 in the work area Q1, within a certain period of time, the magnetic field signal generated by the signal generator 1' on its boundary line 2' may interfere with the magnetic field signal generated on the boundary line 1 of the work area Q1.

[0056] In a specific embodiment of the present invention, by judging whether the waveform of the real-time feedback signal received at a predetermined position in a predetermined period is consistent with the waveform formed by the theoretical feedback signal at a predetermined position in the predetermined period, it is indirectly judged whether the magnetic field signals in the two areas interfere with each other, and adjustments are made based on the judgment result.

[0057] For ease of understanding, continue Figure 2 As shown, the following specific examples are described for reference. In the following example, A is the theoretical feedback signal that should theoretically be received after the signal generator 1 in the working area Q1 transmits the electric pulse signal, B is the interference feedback signal formed after the signal generator 1' in the adjacent working area Q2 transmits the electric pulse signal, and A+B is the real-time feedback signal actually received by the magnetic field sensing sensor 3.

[0058] like Figure 3 The example shown is: the theoretical feedback signal A and the interference feedback signal B have the same period, opposite pulse directions, and a phase difference of one pulse. The amplitude of the interference feedback signal B is smaller than the amplitude of the theoretical feedback signal A. After signal superposition, the actual feedback signal formed has an unchanged period and partially distorted amplitude compared to the theoretical feedback signal. Specifically, the falling edge at time t1 is extended; in the interval t1-t2, the amplitude in the opposite direction increases; and the falling edge at time t3 is extended. In this way, it is confirmed that the waveform received by the real-time feedback signal at a predetermined position in the predetermined period is inconsistent with the waveform formed by the theoretical feedback signal at the predetermined position in the predetermined period.

[0059] In the implementation methods of the present invention, there are multiple ways to implement step S3; step S3 adjusts the transmitted electrical pulse signal, including: adjusting the phase and / or period of the transmitted electrical pulse signal so that the waveform received by the real-time feedback signal at a predetermined position in a predetermined period is consistent with the waveform formed by the theoretical feedback signal at a predetermined position in the predetermined period.

[0060] In a specific embodiment of the present invention, the following schemes can be used to implement step S3:

[0061] Specifically, in the first preferred embodiment of the present invention, step S3 of adjusting the transmitted electrical pulse signal includes: preconfiguring a periodic signal group, wherein the periodic signal group includes a plurality of periods of different sizes;

[0062] Adjusting the period of the transmitted electrical pulse signal so that a waveform of the real-time feedback signal received at a predetermined position in a predetermined period is consistent with a waveform formed by the theoretical feedback signal at the predetermined position in the predetermined period includes:

[0063] M1. Randomly select any period from the periodic signal group, and use the currently selected period to adjust the transmitted electrical pulse signal, and determine whether the waveform of the real-time feedback signal received at a predetermined position in the predetermined period is consistent with the waveform formed by the theoretical feedback signal at the predetermined position in the predetermined period.

[0064] If so, keep transmitting the electric pulse signal at the current cycle;

[0065] If not, loop and execute M1.

[0066] In a second preferred embodiment of the present invention, step S3 of adjusting the transmitted electrical pulse signal includes: N1, alternately adjusting the period and phase of the transmitted electrical pulse signal, and determining whether the waveform of the real-time feedback signal received at a predetermined position in a predetermined period is consistent with the waveform formed by the theoretical feedback signal at the predetermined position in the predetermined period,

[0067] If so, keep transmitting the electric pulse signal at the current cycle or the current phase;

[0068] If not, loop and execute N1.

[0069] In a third preferred embodiment of the present invention, step S3 of adjusting the transmitted electrical pulse signal includes: P1, adjusting the period of the transmitted electrical pulse signal, and determining whether the waveform of the real-time feedback signal received at a predetermined position in a predetermined period is consistent with the waveform formed by the theoretical feedback signal at the predetermined position in the predetermined period,

[0070] If they are consistent, the electric pulse signal is continuously transmitted at the current cycle;

[0071] If not, proceed to step P2;

[0072] P2, looping step P1 N times. If, after the Nth execution of step P1, the waveform of the real-time feedback signal received at the predetermined position of the predetermined period is still inconsistent with the waveform formed by the theoretical feedback signal at the predetermined position of the predetermined period, then executing step P3;

[0073] P3. cyclically adjust the phase of the transmitted electrical pulse signal until the waveform of the real-time feedback signal received at the predetermined position of the predetermined period is consistent with the waveform formed by the theoretical feedback signal at the predetermined position of the predetermined period.

[0074] In a fourth preferred embodiment of the present invention, step S3 of adjusting the transmitted electrical pulse signal includes: continuously adjusting the transmitted electrical pulse signal by adjusting one of the period or the phase;

[0075] If within the predetermined time, the waveform of the real-time feedback signal received at the predetermined position of the predetermined period is still inconsistent with the waveform of the theoretical feedback signal formed at the predetermined position of the predetermined period, then the transmission electric pulse signal is adjusted by adjusting the period or the phase.

[0076] Wherein, within each predetermined period, the selected period and phase are different.

[0077] To facilitate understanding, two examples are described for reference.

[0078] Combine Figure 4 As shown, Figure 4 exist Figure 3 Based on the example shown, the transmitted electric pulse signal is adjusted by adjusting the period of the transmitted pulse signal. Before the adjustment, the real-time feedback signal received by the magnetic field sensing sensor 3 is A+B. Correspondingly, the waveform of the signal A+B is inconsistent with the waveform of the theoretical feedback signal A at a predetermined position of the predetermined period. At this time, the waveforms are made consistent by adjusting the period of the transmitted pulse signal. Specifically, the period of the transmitted pulse signal is adjusted from T1 to T2, where T2 is less than T1. In other real-time methods of the present invention, T2 may also be not less than T1. C is the theoretical feedback signal generated by the transmitted electric pulse signal with a period of T2. C+B is the real-time feedback signal actually received by the magnetic field sensing sensor 3. As shown in the figure, after the feedback signal formed by the transmitted electric pulse signal with a period adjusted from T1 to T2 is interfered by the interference feedback signal, the waveform of the real-time feedback signal C+B received at the predetermined position of the predetermined period is consistent with the waveform formed by the theoretical feedback signal C at the predetermined position of the predetermined period. At this time, when the robot is working in the working area Q1, it will not be affected by the magnetic field signal in the Q2 area, and the magnetic field signal in the area Q1 can be accurately identified to achieve robot positioning.

[0079] Combine Figure 5 As shown, Figure 5 exist Figure 3Based on the example shown, the transmitted electric pulse signal is adjusted by adjusting the phase of the transmitted pulse signal. Before the adjustment, the real-time feedback signal received by the magnetic field induction sensor 3 is A+B. Correspondingly, the signal A+B is inconsistent with the waveform of the theoretical feedback signal A at a predetermined position in a predetermined period. At this time, the waveforms are made consistent by adjusting the phase of the transmitted pulse signal. Specifically, the transmitted pulse signal is delayed; C is the theoretical feedback signal generated by the delayed transmitted electric pulse signal; C+B is the real-time feedback signal actually received by the magnetic field induction sensor 3. It can be seen from the figure that after the feedback signal formed by the delayed transmitted electric pulse signal is interfered by the interference feedback signal, the waveform of the real-time feedback signal C+B received at the predetermined position in the predetermined period is consistent with the waveform formed by the theoretical feedback signal C at the predetermined position in the predetermined period. At this time, when the robot works in the working area Q1, it will not be affected by the magnetic field signal in the Q2 area, and the magnetic field signal in the area Q1 can be accurately identified to achieve robot positioning.

[0081] In addition, the magnetic field sensing sensor 3 is also used to implement steps S1 and S2 in the signal anti-interference method applied to the robot boundary system, and the signal generator 1 is also used to implement step S3 in the signal anti-interference method applied to the robot boundary system, which will not be repeated here.
