At present, offset press is as a kind of printing machinery of main flow, and its efficient, high-quality, low advantage originally makes it in occupation of the leading position of printing machinery.But, our discovery of always be engaged in offset press research and development, making, the communication modes of the control system of the China ink amount control in the offset press and China ink amount feedback also has incomplete place.
The communication modes of the control system of the China ink amount control in the outer offset press of Present Domestic and China ink amount feedback has following several mode
L RS-232 communication
Shortcoming: communication distance is short, speed is low etc.
L RS-485 communication
Advantage: be a kind of relatively economical, have that suitable strong noise suppresses, the communications platform of relatively high transfer rate, long transmission distance and wide common mode range.The RS-485 standard is used in many different fields, as data transmission link as a kind of electrical code of multiple spot differential data transmission.
Shortcoming: although present in the fieldbus that China uses, RS-485 half-duplex, full duplex asynchronous communication bus also are the data communication bus that is widely used.But be based on the characteristics that a main frame can only be arranged on the RS-485 bus, it often is applied between centralized Control hinge and the decentralised control unit.Because many limitation that RS-485 bus itself exists, along with the development of science and technology, the bus efficiency of RS-485 is low, the real-time of system is poor, reliability communication is low, later maintenance cost is high, network engineering debugging complicated, transmission range node undesirable, that monobus can articulate is few, use the shortcoming such as dumb coming out slowly.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of reliability, real-time, flexibility, ease of use advantages obviously and long transmission distance, efficient is high, cost is low offset printer ink amount control system.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of offset printer ink amount control system, its innovative point is: comprise CCU, China ink amount motor, China ink amount feedback potentiometer, CAN control module, CAN transceiver, CAN bus network, CCU, be used for whole system is monitored and control operation, described CCU comprises central computer and China ink amount control button China ink post show bar, and central computer is equipped with can realize the printed document data storage, call and the control of whole black keys and the ink control system software of position monitoring; China ink amount control button China ink post show bar Real-Time Monitoring China ink amount also can be carried out the control of China ink amount at any time; China ink amount motor, corresponding one by one with each black key, be used for driving black key and reciprocatingly slide along offset press ink fountain roller direction; China ink amount feedback potentiometer, corresponding one by one with each black key, be used for feeding back current black key position; The CAN control module, being used for one to one, the black amount of control motor also gathers the feedback information that China ink is measured feedback potentiometer; The CAN transceiver is used for communication man-to-man and the CAN module, and by CAN bus network and central computer communication.
Further, adopt cable completion system distribution, exchange control signal between central computer, monitor and the operating desk of described CCU inside.
Further, be equipped with modem in the described CCU, modem can connect with the telephone wire of analog signal ink control system software is carried out remote detection, revises and program is upgraded.
Further, 32 high-performance kernel MCU of the integrated CAN protocol controller of described CAN control module and by this microprocessor control China ink amount motor.
Further, described China ink amount motor is at a high speed than direct current China ink amount motor.
Further, described CAN transceiver by the CAN control module indirectly to China ink amount motor power supply and control signal is provided.
Further, adopted the isolated can transceiver module in the described CAN bus network.
The invention has the advantages that: adopt central computer to install and to realize the printed document data storage, call and the configuration software of the functions such as the control of whole black keys and position monitoring, utilize the CAN bus communication, the forward or reverse of the automatic control China ink of realization amount motor and the function of real-time China ink amount feedback, feedback and closed loop control function are measured by realization offset press printing process China and Mexico.
The CAN communication modes not only has obvious advantage at aspects such as communication capacity, reliability, real-time, flexibility, ease for use, long transmission distance, cost are low, and supports CAN2.0 A/B agreement; Bit rate (up to 1 Mbps) able to programme; Have 32 message objects; Each message object has the identifier mask off code of oneself; Comprise maskable interrupts; The CAN(TTCAN that triggers in the time) forbids automatically retransmitting the pattern of sending in the application; The self-test operation has programmable loop back mode; Has programmable fifo mode; Data length from 0 to 8 byte; By CAN0Tx and CAN0Rx pin and outside CAN PHY seamless link.When signal transmission distance reached 10KM, the CAN bus still can provide the message transmission rate up to 5Kbps.Guaranteed the stable, reliable, efficient of black amount control system information exchange.
Utilize the telephone wire of modem and analog signal to link up with regard to can be used to the system of central computer among the present invention is carried out remote detection, and can make amendment and program is upgraded software.Because the microprocessor of the system among the present invention can record the mechanical characteristic of the black key of assembling, transmission, China ink amount motor and accurately locate the needed parameter of electric machine, thereby reduced the possibility that mechanical part damages the largelyst.
