Lingchen Technology IO Module Pressure Displacement Acquisition Application
Lingchen Technology's independently developed LCTE-MINI-C2A4 module, with its multi-channel synchronous acquisition capability and high-precision data processing characteristics, provides an efficient solution for monitoring physical quantities such as pressure, displacement, and torque in industrial scenarios. This module integrates encoder acquisition, analog input, threshold triggering, and latching functions, making it particularly suitable for scenarios requiring simultaneous recording of displacement and force, such as button testing and precision mechanical motion analysis.
I. Core Functions and Technical Parameters
1. Multi-channel synchronous acquisition capability: Encoder acquisition: Supports 2-channel differential input (AB phase signals), receiving frequency 20MHz. Analog input: 4-channel 16-bit resolution, supports ±10V voltage input, sampling rate up to 20kHz.
2. Intelligent triggering and latching voltage threshold triggering: 2 channels support ±10V threshold setting. When the analog voltage exceeds or falls below the threshold, a level inversion is triggered. This level signal can be connected to the driver limit switch, thereby triggering the shaft to stop immediately. Position latching function: 2 latching channels (LTC+/-). Upon detecting a 5V voltage difference, the current encoder position is immediately stored in the FIFO queue, ensuring accurate capture of critical displacement data.
3. Flexible working modes: Polling mode: Real-time reading of 2-channel encoder position coordinates and 4-channel analog voltage values, suitable for routine monitoring. Continuous acquisition mode: The main function, enabling synchronous acquisition of encoder position and analog data, ensuring one-to-one correspondence between the two sets of data. A single continuous acquisition sample size can reach 200K, with a maximum sampling rate of 20kHz.
II. Analysis of Typical Application Scenarios
Scenario 1: Button Pressure and Displacement Monitoring Background: To test the relationship between spring force and displacement during button pressing, verifying product durability and tactile consistency. Implementation: The encoder records the displacement of the pressing shaft in real time and outputs an AB phase differential signal to the C2A4 module; the pressure sensor converts the button spring force into a voltage signal, which is transmitted to the C2A4 through the analog channel. Advantages: Synchronous acquisition ensures a complete pressure-displacement curve; 200K sample size supports long-cycle motion analysis.
Scenario 2: Laptop Flip Angle and Torque Monitoring Background: To detect torque changes in the flip hinge at different angles and optimize the structural design. Implementation: The encoder monitors the flip angle and outputs real-time position data through AB phases; the torque sensor converts the torque value into a voltage signal, which is synchronously acquired by the C2A4. Advantages: 20kHz sampling rate accurately captures dynamic changes; threshold trigger function allows setting torque alarm thresholds.
III. Driving the Intelligent Upgrading of Industry
Lingchen Technology's LCTE-MINI-C2A4 module solves the challenge of collaborative analysis of displacement and force signals in industrial scenarios through high-precision synchronous acquisition technology and intelligent functional design. Its multi-channel, high sampling rate, and large-capacity data storage characteristics make it suitable not only for precision manufacturing and quality control but also extend to fields such as robot motion control and automated testing, providing reliable data support for equipment status monitoring and product optimization.
