Actual strip tracking data acquisition module is responsible for the signal data of on-the-spot each section actual acquisition is uploaded in the main line control system, realize the trace information with steel at collection surface detection system and calibrator system requirements the transmission of data position place, when the arrival of band steel taping head requires the position, from the signal data of actual acquisition, take out current steel reel number and the weld seam signal of taking the lead to arrive this position by this module.
Data transmission module is divided into two parts, a part is responsible for obtaining according to the steel reel number that actual strip tracking data acquisition module is obtained 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 surface detecting system and the calibrator system by this module instrument is surveyed real data and signal condition returns to the monitoring that the main line control system is carried out measured data and meter status, and the filing management of measured data.
According to function data transmission module is divided into that forwarding mechanism is obtained, defined to master data, definition reception mechanism, receive data are stored 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, if need new communication, then can directly increase in 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 send data message to surface detecting system and calibrator system according to triggering clock, simple to operation, modularized design only needs to define input and output.The data 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 by the mode of man-machine interface, operating personnel can be by the main line control system monitoring interface instrument system is independently carried out control operation, comprise the automatic control mode of autonomous system and manual control model.Consider security row and the reasonability of equipment control, it is as follows that control need to be satisfied service condition:
1) produces the line specific part (position of producing line and install for surface detecting system and calibrator, calibrator is the planisher place) when being 30 m/mins creep speed, speed allows to drop into calibrator, and purpose is to realize the automatic input of equipment under the prerequisite that guarantees the calibrator device security;
2) the product line breaks down and causes the parking of stove district or the broken belt signal occurs, and calibrator equipment automatically shifts out and is positioned at the off-line position, prevents damage equipment.
2, the combination of actual strip tracking data acquisition module, data transmission module, monitoring and three kinds of modules of operational module and main line control system
The basic background of three kinds of data module realizations is based on the main line control system, actual strip tracking data acquisition module is based in the main line control system and realizes on the strip tracking communication function basis, utilize the positional information of its strip tracking, 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 neoteric module on the basis of the former environment of main line control system, realizes the sending and receiving of data.The measured data that data transmission module receives is implemented in demonstration and the operation control function of main line control system operation interface by monitoring and operational module.
Ethernet communication is adopted in communication of the present invention, give special instrument system by 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 in real time simultaneously status information and the operating control signal of special instrument, realized the unification of master control interface monitoring and operation, operating personnel can directly just can operate control to new special instrument by 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, former main line system is transferred to special instrument system with weld seam signal, coil of strip master data automatically before weld seam arrives special instrument, special instrument system actual measurement detection data are passed in real time the main line system back and are carried out data filing and distribution, and are complementary as the information of product volume with the final products volume.The data of passing in real time simultaneously the main line system 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 operate control to new special instrument by former main line operation interface, realized the uniformity of operation, the real-time of monitoring.
