Description
Technical field
The invention belongs to the cold rolled sheet technical field, particularly relate to method a kind of and surface detecting system and the realization communication of calibrator system.
Background technology
In cold rolled sheet was produced, surface detecting system and calibrator all were self contained instruments, and oneself independently system is arranged; System has no communication with main line control; If do not realize the communication with main line control system, can't realize the location of surveying record and actual coil of strip in surface detecting system and the calibrator system so, the coupling of measured data and corresponding coil of strip; Also can't realize simultaneously the uniformity of operating, can't measured data be uploaded the higher level and carry out data management and statistical analysis.
Summary of the invention
The object of the present invention is to provide method a kind of and surface detecting system and the realization communication of calibrator system; Having solved is not having under the situation that machinery and electric hardware changes, single in main line control system framework 3 kinds of data modules through independent research realize function that the controling of surface detecting system and calibrator, condition monitoring and communication data are transmitted.

Data transmission module is divided into two parts; The steel reel number that a part is responsible for obtaining according to actual band steel tracking data acquisition module obtains the essential information and the sequence information of this volume, is transferred to surface detecting system and calibrator system after the essential information coupling of data transmission module with this position steel reel number and this volume; Another part realizes that surface detecting system and calibrator system survey real data and signal condition through this module with instrument and return to main line control system and carry out the monitoring of measured data and meter status, and the filing management of measured data.
According to function data transmission module being divided into master data obtains, defines forwarding mechanism, definition reception mechanism, receives storage four parts; Realize the data transmission module function according to four parts separate but that connect each other; Master data is obtained and is adopted self-defining coil of strip structure of arrays; Steel reel number, essential information, sequence information are encapsulated as an extendible structure, and new if desired information transmission then can directly increase on this structure; Simple to operate; The fixing clock that triggers of forwarding mechanism definition, this clock can be adjusted according to actual needs at any time, regularly sends data message to surface detecting system and calibrator system according to triggering clock; Simple to operation, modularized design only need define input and output.Storage realizes surveying return data and product volume coupling stores in the storage system.
Monitoring and operational module are responsible for meter status and measured data that surface detecting system and calibrator system feedback are returned are monitored and operated through the mode of man-machine interface; The monitoring interface that operating personnel can control system through main line carries out control operation to instrument system independently, comprises the automatic control mode of autonomous system and manual control model.Consider the security row and the reasonability of Equipment Control, it is following that control need be satisfied service condition:
1) producing the line specific part (is that surface detecting system and calibrator are producing the position of installing on the line; Calibrator is the planisher place) when being 30 meters/minute creep speed, speed allows to drop into calibrator, and purpose is under the prerequisite that guarantees the calibrator device security, to realize the automatic input of equipment;
2) the product line breaks down and causes the parking of stove district or the broken belt signal occurs, and calibrator equipment shifts out automatically and is positioned at the off-line position, prevents damage equipment.
2, actual band steel tracking data acquisition module, data transmission module, monitoring and three kinds of modules of operational module are controlled combining of system with main line
The basic background of three kinds of data module realizations is based on main line control system; Actual band steel tracking data acquisition module is based in the main line control system and realizes on the band steel tracking communication function basis; The positional information of utilizing its band steel to follow the tracks of, the band steel reel number of the product line specific location of surface detecting system and calibrator system requirements is obtained in realization.Data transmission module is a neoteric module on the basis of the former environment of main line control system, realizes the transmission and the reception of data.The measured data that data transmission module receives is implemented in the demonstration of main line control system operation interface and controls function through monitoring and operational module.
Ethernet communication is adopted in communication of the present invention; Give special instrument system through 4 kinds of data modules with weld seam signal, coil of strip master data and order requirements transfer of data; And receive actual measurement that special instrument system returns and detect data and carry out data filing and distribution, and mate with final products.Receive the status information and the operating control signal of special instrument simultaneously in real time; Realized the unification of master control interface monitoring and operation; Operating personnel can directly just can control new special instrument through former main line operation interface, have realized the uniformity of operation, the real-time of monitoring.
Ethernet communication and DP Netcom news are adopted in communication; Arrive the before former main line of special instrument system at weld seam and automatically weld seam signal, coil of strip master data are transferred to special instrument system; Special instrument system actual measurement detection data in real time is passed the main line system back and is carried out data filing and distribution, and is complementary as the information of product volume with the final products volume.The data of passing simultaneously the main line system in real time back are presented on the master control interface; The control operation signal of special instrument system also turns back in the main line control system; Operating personnel can directly just can control new special instrument through former main line operation interface; Realized the uniformity of operation, the real-time of monitoring.
