[0003] Existing technology and its shortcomings: 1. Environmental sensitivity: Optical sensor systems are very sensitive to ambient light; for example, dust particles or liquid droplets falling on the optical path may block the light propagation, resulting in reduced measurement accuracy.

[0004] 2. Susceptible to interference: Since the optical probe system relies on infrared light for data transmission, in actual applications, if it encounters other infrared light sources or obstacles, it is easy to cause signal interference, affecting the reliability and accuracy of the data.

[0005] 3. Limited transmission distance: The effective transmission distance of optical probe systems is relatively short, which limits their scope of application, especially when used on large machine tools and other equipment that need to cover a wide working area.

[0006] 4. Poor deployment flexibility: Compared with radio probes, optical probe systems are not flexible enough to be deployed in different machine tool configurations and changing working environments, and are difficult to adapt to complex on-site conditions.

[0007] 5. Not suitable for simultaneous measurement of multiple points: In situations where multiple probes need to work simultaneously, such as online measurement of multi-spindle machine tools, optical probe systems are prone to not functioning properly due to mutual light interference.

[0008] Therefore, the prior art has deficiencies and needs further improvement. Summary of the invention

[0042] Battery wide voltage input → anti-reverse protection circuit → DC-DC conversion circuit.

[0043] Figure 3 :The probe detection module is to pass the detection voltage between the two probe electrodes. After the external force is applied, the distance between the two probe electrodes is changed, so that the resistance between the two probe electrodes changes. Because the detection voltage is passed, the voltage between the probe electrodes also changes when the resistance changes. The changed voltage reaches the voltage comparison circuit after RC filtering and hysteresis circuit to compare with the reference voltage. If the input voltage is higher than the reference voltage, the level output module outputs a high level to the system, otherwise the level output module outputs a low level to the system.

[0044] The voltage comparator is connected to the voltage filtering hysteresis circuit, the reference voltage regulator and the level conversion circuit respectively, and the level conversion circuit is connected to the level output circuit.

[0045] Figure 4 The wireless communication module consists of a communication interface for communicating with the MCU system unit, a transmission buffer, a receiving buffer, a register mapping unit, a baseband unit, a GFSK / FSK frequency modulation and demodulation unit, a PA power amplifier unit, an RF PLL, a power management unit, and an LNA low noise amplifier unit. In the transmission mode, the data received from the host is stored in the transmission buffer. The baseband unit modulates the data to be sent according to the specified frequency through the GFSK modulator, amplifies it through the PA power amplifier, and then transmits it into the air. In the receiving mode, the wireless signal in the air that meets the specified frequency is detected, amplified by the LNA low noise amplifier, and sent to the GFSK demodulator to demodulate the real data information. After the baseband unit notifies the MCU host, the host actively reads the relevant registers to obtain the received data.

[0046] in: GFSK / FSK: This is a type of modem used in wireless communications to convert digital signals into analog signals suitable for transmission over wireless channels (modulation), and to restore received analog signals into digital signals (demodulation). GFSK stands for Gaussian Frequency Shift Keying and FSK stands for Frequency Shift Keying.

[0047] Send buffer: used to temporarily store data to be sent in order to provide a stable and continuous data flow during the sending process.

[0048] PA (Power Amplifier): Used to amplify the modulated signal to ensure that the signal has sufficient power to be transmitted to the receiving end.

[0049] Communication interface: used to connect the wireless communication module with other electronic devices, such as microcontrollers or computers.

[0050] The baseband unit (BBU) is a key component in mobile communication systems. It is responsible for processing baseband signals, which are the most basic signal forms, usually referring to signals with a frequency range near zero frequency (from DC to several hundred kHz). The main functions of the baseband unit include digital signal processing, modulation and demodulation, signal encoding and decoding, channel coding, signaling processing, etc. It is also responsible for managing and controlling wireless resources, such as allocating frequencies and time slots to ensure that the transmitted signals can be transmitted at a specific time and frequency.

[0051] Power management: responsible for managing the power supply of the module, ensuring that each part of the module receives appropriate voltage and current.

[0052] RF PLL (Radio Frequency Phase Locked Loop): Used to generate a stable RF signal to ensure the stability and accuracy of wireless communication.

[0053] Register mapping: Mapping the addresses of hardware registers in software so that the software can control the hardware by reading and writing these addresses.

[0054] LNA (Low Noise Amplifier): Used to amplify weak received signals while minimizing noise amplification.

[0055] Receive buffer: used to temporarily store received data to provide a stable and continuous data flow during processing.

[0056] Demodulator: The opposite of modulator, its function is to convert the received analog signal into a digital signal.

[0057] Connection relationship: The data in the send buffer is modulated by the modulator, amplified by the PA, and finally sent out through the communication interface. The receiving end receives the signal through the communication interface, amplifies it through the LNA, demodulates it by the demodulator, and finally stores it in the receive buffer.

[0058] Working process: 1. Power on: It will automatically power on when receiving valid power on data via wireless signal. After power on, the green indicator light will flash at a frequency of 1Hz.

[0059] 2. Probe detection: The probe detection module detects the resistance change between the probe electrodes in real time. After filtering and hysteresis, if the voltage between the probe electrodes is lower than the reference voltage, it outputs a high level, otherwise it outputs a low level.

[0060] 3. The MCU system unit detects the output level signal of the probe detection module. If it changes from low level to high level, the MCU system unit sends trigger data to the wireless communication module. The wireless module is selected and modulated by the GFSK / FSK unit and then amplified by the PA power amplifier to transmit the RF signal. The red indicator light is always on and the green indicator light is off. If it changes from high level to low level, the MCU system unit sends reset data to the wireless communication module. The wireless module is selected and modulated by the GFSK / FSK unit and then amplified by the PA power amplifier to transmit the RF signal. The red indicator light is off and the green indicator light flashes at a frequency of 1Hz.

[0061] 4. Shutdown: When receiving effective shutdown data through wireless signals, it will automatically shut down, all indicator lights will go out, and the MCU system unit will turn off the power supply of other units and enter the sleep mode to extend the usage time.

[0062] How it works Power on: When the system receives a valid wireless power-on signal, it automatically starts up. At this time, the green LED indicator will flash at a frequency of 1Hz, indicating that the system has entered normal working state.

[0063] Probe detection: The probe detection module monitors the resistance change between the two probe electrodes in real time. When an external force acts on the probe, the distance between the two electrodes changes, resulting in a change in resistance.

[0064] The resistance change is converted into a voltage signal, which is then processed by RC filtering and hysteresis circuits and compared with a preset reference voltage.

[0065] If the voltage between the probe electrodes is lower than the reference voltage, a high level is output; otherwise, a low level is output.

[0066] Data processing and wireless transmission: The embedded MCU system unit continuously monitors the output level signal of the probe detection module.

[0067] When the MCU system unit detects a change from low level to high level, it means that the probe has been triggered, and the MCU system unit will send trigger data to the 2.4G wireless RF transmitter and receiver module.

[0068] The wireless communication module modulates the trigger data at the specified frequency through the GFSK / FSK modulator, and transmits it after being amplified by the PA power amplifier. At this time, the red LED indicator is always on and the green LED indicator is off.

[0069] If the MCU system unit detects that the level changes from high to low, it means that the probe has been reset, and the MCU system unit will send reset data to the wireless communication module. Similarly, the data is modulated and amplified before being transmitted. At this time, the red LED indicator turns off and the green LED indicator resumes flashing at a frequency of 1Hz.

[0070] Shutdown: When the system receives a valid wireless shutdown signal, it executes the shutdown procedure. All indicators go out, and the MCU system unit turns off the power supply to other units and enters sleep mode to extend the battery life.

[0071] Automatic frequency hopping communication: The wireless communication module adopts automatic frequency hopping technology, which can avoid signal interference and ensure stable data transmission in an environment where multiple probes work simultaneously.

[0072] The system can automatically switch between different channels to avoid possible interference sources and ensure communication quality.

[0073] Power Management: The DC power module is responsible for stepping down the wide voltage input from the battery to the 3.3 volt voltage required by the system, and provides reverse connection protection, voltage regulation, overvoltage protection, overcurrent protection and short circuit protection.

[0074] In the shutdown state, the MCU system unit will cut off the power supply to other units and enter a low-power sleep mode to save power.

[0075] Through the above steps, the present invention realizes accurate measurement of workpieces in complex and changeable working environments, supports simultaneous online measurement of multiple probes, and improves the flexibility and reliability of the system.
