The invention discloses a
communication control circuit for a
laser tracker, which comprises a
digital signal processor, an acquisition module, a communication module, and a
signal driving module. The control part of the
digital signal processor of the
communication control circuit only shoulders closed-
loop control of the outermost layer position, and speed control and current closed-
loop control are realized by the communication module in outer
servo driving. In addition, the
communication control circuit of the invention also adopts a
modular design, and a
testability design and an
extensibility design are introduced. The circuit of the invention has complete integrated functions, the control part only shoulders closed-
loop control of the outermost layer position, computational burden and real-time performance are reduced after
decomposition, and hardware foundation is laid for adopting advanced
control algorithm and improving the control frequency; monitoring on operation states of each module and the overall body is enhanced, and the debugging efficiency and the
troubleshooting efficiency are improved; and the
servo system which does not have a high real-time
performance requirement can be directly used a current, speed and position three-
closed loop integrated control and
communication unit.
