Description

Technical Field

[0001] This invention relates to the field of turntable controller technology, and in particular to an embedded architecture turntable controller. Background Technology

[0002] Currently, many turntables adopt a centralized control method based on PCs. PC-based control systems offer advantages such as powerful hardware and software capabilities, abundant development resources, and easy achievement of high performance. However, they also have some unavoidable problems. For example, PCs were originally designed for data processing and file management, resulting in a relatively complex structure, high cost, and many of the functions they provide are unnecessary for real-time control. Furthermore, PC system hardware is not designed for real-time control and cannot adequately meet its requirements. The operating systems and hardware modules relied upon by PC-based turntable control platforms, such as Windows, lack independent intellectual property rights. Therefore, PC-based turntable control systems actually increase costs and waste resources. Based on this, this invention proposes an embedded architecture turntable controller to solve the above-mentioned technical problems. It possesses unique advantages such as small size and low power consumption, improving the stability, reliability, and flexibility of the control system. More importantly, it allows for upgrades and updates to the control kernel, hardware platform, control algorithm, and operating system according to actual needs, effectively solving problems related to cost and independent controllability of turntable controllers. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an embedded architecture turntable controller with unique advantages such as small size and low power consumption, which improves the stability, reliability, and flexibility of the control system. More importantly, the control kernel, hardware platform, control algorithm, and operating system can be upgraded and updated according to actual needs, effectively solving problems such as cost and independent controllability of turntable controllers.

[0009] As a preferred embodiment, the angle measurement processing module collects turntable angle data through an angle measurement signal cable and sends it to the FPGA processor via parallel communication to provide angle feedback for the turntable closed-loop control.

[0010] As a preferred embodiment, when the FPGA chip performs angle acquisition, it acquires signals through sensors and extracts angle information about the target from them. The main role of the FPGA in this process is to efficiently perform signal synchronization, sampling, and preprocessing. Furthermore, the FPGA can process data streams from multiple sensors in parallel. These sensors typically acquire data at different angles, times, or locations.

The drive module drives the turntable's axes to run, realizing closed-loop control of the turntable. This turntable controller has an embedded architecture, which can be configured and programmed as needed. The control core, hardware platform, control algorithm, operating system, etc. can be upgraded and updated according to actual needs, effectively solving the problems of cost and independent controllability of turntable controllers.
