Description

Distributed all-in-one servo driving device Technical Field The application relates to the technical field of servo driving, in particular to a distributed all-in-one servo driving device. Background In the industrial automatic production process, the multi-axis control technology is widely applied to the fields of various mechanical equipment such as a numerical control machine tool, an automatic production line, a robot and the like, and plays a key role in realizing high-precision, high-speed and high-reliability operation of the equipment. Early, multi-axis control relied primarily on a centralized control architecture. In this centralized mode, a central controller takes over the entire control task of the plurality of motor shafts. It needs to process feedback information from the individual axes and issue control commands to the individual axes. However, this architecture has a number of problems that are difficult to overcome. With the increase of the number of axes, the operation load of the central controller is increased sharply, so that the data processing speed cannot follow the actual demand, and the control response is delayed. For example, in a large-scale automatic production line, a plurality of motor shafts cooperatively operate, and a centralized controller faces mass data and cannot accurately regulate and control each shaft in time, so that the production efficiency is low. Moreover, once the central controller fails, the whole multi-axis control system falls into paralysis, and the reliability of the system is extremely poor. In order to overcome the disadvantages of centralized control, distributed servo drives have been developed. The distributed architecture disperses multiple servo drives in different positions, each of which is independently responsible for controlling one motor shaft. The drivers realize data interaction and cooperative work through a high-speed communication network. The mode greatly reduces the operation pressure of a single controller and improves the control response speed. Because each driver is close to the controlled motor, the distance of signal transmission is reduced, the signal attenuation and interference risks are reduced, and the synchronous control precision during multi-axis linkage is greatly improved. Meanwhile, the distributed architecture has good fault tolerance, and when an individual driver fails, other drivers can still work continuously, so that the continuous operation of the system is ensured. However, the existing distributed servo driver still has a plurality of technical problems in multi-axis control. On one hand, the communication among the shafts of the traditional distributed servo driver has delay, so that accurate synchronous control is difficult to realize during multi-shaft linkage, and the operation precision and efficiency of equipment are seriously affected. On the other hand, when the system needs to expand the number of axes, the architecture of the existing distributed servo driver often faces compatibility difficulties, and the cost of adding a new axis is high and the implementation difficulty is high. Meanwhile, when applied to the head of the device, vibration problems can be brought due to frequent movements, data communication can be affected, and the like. These problems limit the further development and application of distributed servo drives in the field of multi-axis control. Disclosure of utility model Aiming at the technical problems, the application provides a distributed all-in-one servo driving device which can realize distributed multi-axis precise control and has the advantages of small volume, vibration resistance and the like. The application aims to solve the technical problems, and adopts the technical scheme that the distributed all-in-one servo driving device comprises a shared interface board and a plurality of servo drivers, wherein each servo driver comprises an interface board, a control board and a power board, the interface board of each servo driver is connected with the shared interface board, each interface board is provided with a communication port, the shared interface board is provided with an input network port and an output network port, and the input network port, the communication ports on each interface board and the output network port are sequentially connected in series. In one embodiment of the present application, the two sides of the input net mouth are provided with anti-vibration columns, and +. Or, vibration-proof columns are arranged on two sides of the output net mouth. In an embodiment of the present application, any one of an IO port, an encoder port, and a USB port is provided on each interface board, and any one of an IO interface, an encoder interface, and a USB interface is provided on the common interface board, where the IO interface is connected to the IO port, the encoder interface is connected to the encoder port, and the USB interface is connected to the U
