High-precision turntable control system core board

Abstract

The invention discloses a high-precision turntable control system core board which comprises a power circuit, a main control circuit, a parameter storage circuit, an EtherCAT communication circuit, a 422 serial communication circuit, a CAN bus communication circuit, a 485 serial communication circuit, a 232 serial communication circuit, an IO interface circuit, a first 16-bit AD conversion circuit and a second 16-bit DA conversion circuit. According to the invention, a circuit susceptible to interference and a circuit with external radiation are staggered during PCB layout, an analog signal is filtered by an inductor, an EMC experiment can be carried out after a finished product is completed, and the design is optimized after problems are found, so that the use stability and continuity of the rotary table are improved, and the rotary table has universality for different rotary table control systems and is suitable for popularization and application. And the overall design efficiency of the turntable and the debugging efficiency of debugging personnel are improved.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to a core board of a high-precision turntable control system. Background technique [0002] The high-precision turntable is a measuring instrument used in the basic disciplines of engineering and technical science. In recent years, it has been widely used in national defense and military industry, intelligent manufacturing, geological exploration, and marine exploration. The high-precision turntable has high requirements on the control system based on its own high-performance indicators, and in view of the diversification of control requirements, it also has great requirements on the compatibility of control methods, which puts forward higher requirements for the core of the control system - the control board. Require. The control boards currently available on the market have the following disadvantages. Although the price is cheap, the function is single, which is refle...

Problems solved by technology

The control boards currently available on the market have the following disadvantages. Although the price is cheap, the function is single, which is reflected in the fact that it cannot meet the needs of different customers with different control methods; the control is convenient but the logic is simple, and some complex control commands cannot be executed; the environment Poor adaptability, the main reason is that devices with narrow temperature and width are selected for cost reduction during design; the failure rate is high in the application of high-precision turntable control system, the reason is that the crosstalk between hardware systems and the ability of the entire control board to resist external interference are not considered during design , no follow-up experiment

It is proved that no effective solution has been proposed for the problems in related technologies
