[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0030] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] In addition, the term "multiple" should mean two or more.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 As shown, a tracked chassis information interaction device includes a housing, and inside the housing are a signal receiving circuit, an electrical frequency conversion circuit, a filtering circuit, an MCU, a protection circuit, a power supply circuit, a signal transmitting circuit, and an isolation circuit.

[0034] The signal receiving circuit is connected to the frequency conversion circuit, the frequency conversion circuit is connected to the filter circuit, the filter circuit is connected to the MCU, the power supply circuit is connected to the MCU, the protection circuit is connected to the power supply circuit, the isolation circuit is connected to the MCU, and the signal transmitting circuit is connected to the isolation circuit.

[0035] It should be noted that in this embodiment, when receiving signals, the external wireless signal is first received through a signal receiving circuit, and then the received signal is converted into an electrical frequency signal suitable for MCU processing using an electrical frequency conversion circuit. Next, the filtering circuit performs three consecutive filters on the electrical frequency signal, effectively filtering out interference signals in specific frequency bands and ensuring the purity of the useful signal. Afterwards, the MCU processes the filtered signal and controls the signal transmitting circuit to send a corresponding reply signal based on the processing result. During signal transmission, the isolation circuit uses an optocoupler to achieve electrical isolation, blocking interference signals from directly coupling to sensitive components through the circuit, thereby improving the overall circuit's anti-interference capability and communication reliability.

[0036] The specific structure of the aforementioned outer casing (not shown in the figure) can be designed according to actual application scenarios and installation requirements to ensure the stability and durability of the equipment. For example, the casing can be made of high-strength, corrosion-resistant materials to resist physical and chemical erosion in harsh environments. Simultaneously, the shape and size of the casing can be optimized to accommodate the installation space and connection interfaces of different tracked chassis equipment. Furthermore, the casing can be designed with heat dissipation holes or fins to effectively dissipate heat generated inside the equipment, ensuring normal operation in high-temperature environments. These designs further improve the adaptability and reliability of the tracked chassis information interaction equipment.

[0037] The power supply circuit provides a stable power supply to the entire device, ensuring that each circuit module can operate normally. This circuit, consisting of a voltage regulator, power supply, and filter capacitors, provides a stable DC voltage, reducing the impact of voltage fluctuations on the circuit.

[0038] The protection circuit includes fuse F1, resistor R14, and transient voltage suppressor diode D3. Working together, they quickly cut off the power supply or absorb excess energy when abnormal power conditions occur, such as overvoltage or transient pulses, thus protecting other components in the circuit from damage. Specifically, fuse F1 melts when the current is too high, cutting off the circuit and preventing overload; resistor R14, in conjunction with transient voltage suppressor diode D3, discharges excess energy to ground through the conduction of D3 when a transient voltage pulse occurs, thereby protecting the circuit from damage. This design greatly enhances the stability and reliability of the equipment.

[0039] As an optional embodiment of this utility model, the signal receiving circuit may optionally include an antenna J1, capacitors C1, C2, C3, C4, C5, a resistor R1, and a Zener diode U1.

[0040] Antenna J1's pin 1 is grounded. Antenna J1's pin 2 is connected to the negative terminal of capacitor C1.

Capacitor C2's negative terminal is connected to capacitor C3's negative terminal, Zener diode U1's pin 4, and Zener diode U1's pin 2, and is grounded.

Zener diode U1's pin 6 is connected to capacitor C4's positive terminal. Capacitor C4's negative terminal is grounded. Zener diode U1's pin 5 is connected to the input terminal of the frequency conversion circuit.

[0041] like Figure 2 As shown, in operation, the signal receiving circuit first receives external wireless signals through antenna J1. The signal received by antenna J1 is initially coupled through capacitor C1, and then stabilized by a voltage regulation circuit composed of resistor R1 and Zener diode U1 to ensure the normal operation of subsequent circuits. Capacitor C2 performs filtering to further remove high-frequency interference signals and improve signal purity. Finally, the filtered signal is output through pin 3 of Zener diode U1 to pin 4 of converter U2 in the frequency conversion circuit.

[0042] As an optional embodiment of this utility model, the frequency conversion circuit may include a converter U2, an inductor L1, a capacitor C6, a capacitor C7, a resistor R2, a resistor R3, and a resistor R4.

[0043] One end of capacitor C6, one end of resistor R2, pin 1 and pin 4 of converter U2 are all connected to the output of the signal receiving circuit. The other end of resistor R2 is connected to pin 5 of converter U2. The other end of capacitor C6 is connected to pin 2 of converter U2, one end of resistor R4, and one end of capacitor C7, and is grounded. The other end of resistor R4 is connected to one end of resistor R3 and pin 6 of converter U2. The other end of resistor R3 is connected to one end of inductor L1 and the other end of capacitor C7. The other end of inductor L1 is connected to pin 3 of converter U2.

[0044] like Figure 3 As shown, when pin 4 of converter U2 receives a signal from pin 3 of Zener diode U1, converter U2 starts working, converting the received signal from one electrical frequency to another electrical frequency that the MCU can process. Resistor R2 and capacitor C6 form an RC filter circuit to filter out high-frequency noise in the signal and improve signal stability. Meanwhile, resistors R4 and R3 and inductor L1 form an LC oscillation circuit to amplify and shape the signal, ensuring that the signal is accurately transmitted to one end of resistor R5 in the filter circuit.

[0045] As an optional embodiment of this utility model, the filter circuit may optionally include resistors R5, R6, R7, R8, R9, R10, inductors L2, L3, L4, L5, L6, capacitors C8, C9, C10, C11, and C12.

[0046] One end of resistor R5 is connected to the output terminal of the frequency conversion circuit. The other end of resistor R5 is connected to one end of capacitor C8, one end of inductor L2, one end of resistor R6, and one end of inductor L6. The other end of inductor L6 is connected to one end of resistor R7. The other end of resistor R7 is connected to one end of capacitor C9. The other end of capacitor C9 is connected to one end of capacitor C10, one end of inductor L3, one end of resistor R8, and one end of inductor L4. The other end of inductor L4 is connected to one end of resistor R9. The other end of resistor R9 is connected to one end of capacitor C11. The other end of capacitor C11 is connected to one end of capacitor C12, one end of inductor L5, and one end of resistor R10. The other end of capacitor C8 is connected to the other ends of inductor L2, one end of resistor R6, one end of capacitor C10, one end of inductor L3, one end of resistor R8, one end of capacitor C12, one end of inductor L5, and one end of resistor R10.

[0047] like Figure 4As shown, when one end of resistor R5 in the filter circuit receives the output signal from the frequency conversion circuit, the signal passes sequentially through the first filter network consisting of resistor R5, capacitor C8, inductor L2, resistor R6, and inductor L6. In this network, the resistors and inductors work together to provide initial attenuation and phase adjustment of the signal, while capacitor C8 filters out high-frequency noise. Subsequently, the signal is passed to the second filter node consisting of resistor R7 and capacitor C9, which further filters out residual interference frequency components. Finally, the signal passes through the third filter network consisting of resistor R8, inductor L3, capacitor C10, inductor L4, resistor R9, capacitor C11, inductor L5, resistor R10, and capacitor C12. In this network, the signal undergoes multi-stage filtering with a combination of resistors, inductors, and capacitors, effectively filtering out interference signals in specific frequency bands and ensuring that the signal finally transmitted to the MCU has high purity and stability.

[0048] As an optional embodiment of this utility model, the isolation circuit may optionally include diode D1, diode D2, resistor R11, resistor R12, resistor R13, capacitor C13 and optocoupler U3.

[0049] The positive terminal of diode D1 is connected to the MCU, the negative terminal of diode D1 is connected to one end of resistor R11, the other end of resistor R11 is connected to the cathode of diode D2 and pin 1 of optocoupler U3, the anode of diode D2 is connected to one end of resistor R12 and pin 2 of optocoupler U3, the other end of resistor R12 is connected to the MCU, one end of capacitor C13 is connected to one end of resistor R13 and pin 4 of optocoupler U3, the other end of resistor R13 is connected to the power supply circuit, and the other end of capacitor C13 is connected to pin 3 of optocoupler U3 and the signal transmission circuit.

[0050] like Figure 5 As shown, when the MCU sends a signal, it is first rectified by diodes D1 and D2 in the isolation circuit, converting the signal from the MCU into a DC signal suitable for processing by optocoupler U3. The voltage divider circuit composed of resistors R11 and R12 is used to adjust the voltage amplitude of the signal, ensuring that optocoupler U3 can operate normally. Pins 1 and 2 of optocoupler U3 receive the signal from the MCU and ground potential respectively. Through its internal photoelectric conversion mechanism, the electrical signal is converted into an optical signal and transmitted to the output terminal through the isolation layer. At the output terminal, the optical signal is converted back into an electrical signal and smoothed by a filter circuit composed of resistor R13 and capacitor C13 before finally being output to the signal transmission circuit.

[0051] As an optional embodiment of this utility model, the power supply circuit may optionally include a voltage regulator, a power supply, and a filter capacitor;

[0052] The input terminal of the voltage regulator is connected to the output terminal of the power supply, the output terminal of the voltage regulator is connected to one end of the filter capacitor, and the other end of the filter capacitor is connected to the MCU.

[0053] It should be noted that the voltage regulator in the power supply circuit stabilizes the power supply voltage, reduces the impact of voltage fluctuations on the circuit, and ensures that each circuit module can operate normally. The filter capacitor further smooths the power supply voltage, eliminates high-frequency noise in the power supply, and improves the overall anti-interference capability of the device. This allows the tracked chassis information interaction equipment to maintain stable performance in various complex environments.

[0054] As an optional embodiment of this utility model, the signal transmitting circuit may optionally include a DAC, a mixer, a power amplifier, and a transmitting antenna;

[0055] The input of the DAC is connected to the MCU, the output of the DAC is connected to the input of the mixer, the output of the mixer is connected to the input of the power amplifier, and the output of the power amplifier is connected to the transmitting antenna.

[0056] It should be noted that the DAC converts the digital signal output from the MCU into an analog signal, which is then fed into a mixer. In the mixer, the analog signal is mixed with a carrier signal to modulate a radio frequency (RF) signal suitable for wireless transmission. This RF signal is then amplified by a power amplifier to ensure sufficient strength for long-distance transmission. Finally, the amplified RF signal is transmitted to external devices via a transmitting antenna. This enables the tracked chassis information interaction device to effectively communicate wirelessly with external devices, improving the device's interactivity and flexibility.

[0057] As an optional embodiment of this utility model, the protection circuit may include a fuse F1, a resistor R14, and a transient suppression diode D3; one end of the fuse F1 is connected to the power supply, the other end of the fuse F1 is connected to one end of the resistor R14 and the cathode of the transient suppression diode D3, and the other end of the resistor R14 is connected to the anode of the transient suppression diode D3 and the power supply circuit.

[0058] It should be noted that when an abnormal voltage or transient pulse occurs in the power supply circuit, fuse F1 can quickly blow, cutting off the circuit and preventing damage to other components. Simultaneously, resistor R14 and transient voltage suppressor diode D3 work together to dissipate excess energy to ground through the conduction of D3 when a transient voltage pulse occurs, further protecting the circuit. This allows the tracked chassis information interaction equipment to maintain high stability and reliability even under abnormal power conditions, ensuring long-term stable operation of the equipment.

[0059] As an optional embodiment of this utility model, the converter U2 may be model number PL5903.

[0060] As an optional embodiment of this utility model, the MCU may be an STM32F407.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
