[0008] The detector further comprises a 24V switch power supply circuit, and the 24V switch power supply circuit respectively supplies power to the MCU, the linear amplifier, and the magnetic sensor array.

[0009] The detector comprises a shell, the MCU, the magnetic sensor array and the linear amplifier are all arranged in the shell, and the probes of the magnetic sensor array are arranged in a row on one side of the shell.

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same technical meanings as those commonly understood by those skilled in the art to which the present application belongs. The wire bead in the present invention is a rigid ring made of rubber-coated steel wire arranged in a certain cross-sectional shape, and its function is to give the tire bead the necessary strength and rigidity so that the tire is firmly fixed on the rim.

[0024] like Figure 1 As shown, a tire bead ring front and back detector includes an MCU, a magnetic sensor array, and a linear amplifier. The probe signal on the magnetic sensor array is sent to the MCU through the linear amplifier.

[0025] The magnetic sensor array includes a plurality of magnetic sensors, and the plurality of magnetic sensors are arranged in a same plane.

[0026] Preferably, six magnetic sensors are used in the present invention, each of which is connected to the MCU via a linear amplifier. The MCU is also connected to an alarm display system.

[0027] The alarm display system includes a warning light, which is composed of a secondary light and has the function of distinguishing different results, and has the function of emitting red light or green light.

[0028] The detector further comprises a 24V switch power supply circuit, and the 24V switch power supply circuit respectively supplies power to the MCU, the linear amplifier, and the magnetic sensor array.

[0029] The detector comprises a shell, the MCU, the magnetic sensor array and the linear amplifier are all arranged in the shell, and the probes of the magnetic sensor array are arranged in a row on one side of the shell.

[0030] The MCU is connected to the host computer through a built-in Bluetooth module.

[0031] A detection method using the tire bead ring front and back detector, the method comprising: Aligning the probe of the magnetic sensor array in the detector with the wire ring; Each magnetic sensor in the magnetic sensor array collects the data signal of the wire ring below it to obtain a voltage sequence data; The wire ring data is amplified by a linear amplifier and then converted into a digital signal by an ADC built into the MCU; After filtering the digital signal, the detection result is obtained by comparing it with the data pre-stored in the MCU calibration library.

[0032] The data pre-stored in the MCU calibration library include the voltage sequences measured by the magnetic sensor array when the wire ring is placed normally and in reverse. When placed normally, the distance between the magnetic sensor and the wire ring gradually decreases from left to right, and the measured voltage gradually increases. When placed in reverse, the distance between the magnetic sensor and the wire ring gradually increases from left to right, and the measured voltage gradually decreases.

[0033] When the detection result is normal placement, the MCU outputs a signal to control the green light in the alarm display circuit to light up; when the detection result is reverse placement, the MCU outputs a signal to control the red light in the alarm display circuit to light up.

[0034] like Figure 3 and Figure 4 As shown, the detector includes a shell, the MCU, the magnetic sensor array, and the linear amplifier are all arranged in the shell, and the probes of the magnetic sensor array are arranged in a row on one side of the shell.

[0035] like Figure 2 As shown, before use, the 24V switch power supply circuit is used to supply power to the Bluetooth chip, high-precision linear amplifier, magnetic sensor, and alarm display system. Then each module is initialized. When in use, the 6 magnetic sensors collect the wire ring data signal, and after the signal is amplified by the high-precision linear amplifier, the obtained signal is converted into a digital signal through the built-in ADC of the MCU. After multiple data sampling, the data is filtered and processed. The final data after filtering is compared with the data pre-stored in the MCU calibration library to obtain the detection result. The detection result is that when the wire ring is placed normally, the MCU controls the green light of the alarm display system to light up, otherwise the red light is on.

[0036] The host computer calibration library pre-stores the voltage sequences measured by the six magnetic sensors when the wire ring is placed normally and reversely. When the wire ring is placed normally, Figure 5 As shown in the figure (1-6 represent magnetic sensors, and the circle below the magnetic sensor represents the steel wire inside the wire ring), the distance between the 6 magnetic sensors and the wire ring gradually decreases from left to right, and the measured voltage gradually increases, such as Figure 6 As shown in the figure, when placed in reverse, the distance between the six magnetic sensors and the wire ring gradually increases from left to right, and the measured voltage gradually decreases.

[0037] On the whole, the present invention is safe and reliable and can achieve accurate detection. The use of MCU and sensors ensures the precise execution of the entire working process, detects the tire rim in real time, and realizes monitoring by transmitting data to the host computer.

[0038] In summary, the present invention is simple to operate, safe and reliable, and can achieve accurate detection. The use of MCU and sensors ensures the precise execution of the entire working process and real-time detection of tire rims.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
