The present invention discloses a transmitting control apparatus and the control method. The transmitting control apparatus includes: a dual-ported random memory, a transmitting controller, a receiving controller, a transmitting control register, a receiving control register, a transmitting state register, a receiving state register, a check computation / error-correcting coder, a check test / error-correcting encoder, a transmitting interface, a receiving interface and an inside receiving and transmitting bus. The information transmitting and receiving main control device is added with a microprocessor, a read-only random access memory, a read-write random access memory and a main control bus. The multilinked transmitting control system is composed of the transmitting medium and at least twotransmitting control devices. Otherwise, a method of controlling the transmitting between the transmitting control devices is also disclosed. In the present invention, many kinds of link modes are realized through many kinds of topological structures and the complex control requirement of lithography device and other devices can be satisfied. As a result, the performances of high speed, real timeand veracity of the data information transmitting and the diversification of the link transmitting mode are realized.
Description
technical field [0001] The invention relates to data transmission control, in particular to a transmission control device and a control method thereof. Background technique [0002] In industrial devices, due to the need for high precision and high productivity, a large number of control systems for high-speed real-time signal sampling, data acquisition, data exchange and communication transmission are distributed. These systems require us to use various methods to realize the control of sensor signal sampling control, data acquisition control, data exchange control and data transmission communication. Devices that require this control include: integrated circuit manufacturing lithography devices, liquid crystal panel lithography devices, MEMS / MOMS lithography devices, advanced packaging lithography devices, printed circuit board lithography devices, printed circuit board processing devices, and printed circuit board Device placement devices, etc. [0003] In lithography e...
