1747-L553 SLC 5/05 Processor

The ultimate goal of the 1747-L553 data collection is not only to display the required data (e.g., daily volume) on the interface, but also to record the data into a database for later query. The process of displaying the data is easy to realize, which is to take out the contents of the receive buffer in a pre-agreed order. To record the data to the database you need to use the database binding control, used in this project is the adodc control, this control is not included in the common toolbox, still have to follow the method of adding the mscomm control to the toolbar microsoft ado data control6.0 (sp4) (oledb) to add to the toolbox, and then you can drag this control into the form. Then you can drag the control into the form.

1747-L553 In this work, the adodc control is placed in the query screen that is not displayed when the program is running, so that the recording to the database and the query can be completed at the same time, through the setting of the connectionstring of adodc1 (which is required to be connected to the address stored in the database that has been built beforehand), commandtype (which is set because it is necessary to write data to the database), and the commandtype (which is set because it is necessary to write data to the database). The binding is completed by setting the connectionstring (to be connected to the address stored in the pre-established database), commandtype (to be set to 2-adcmdtable because data is written to the database), and recordsource (to be selected as a table corresponding to this adodc1 if the specified database contains more than one table) attributes (other attributes can be set with default values).

1747-L553 control system is a contacted control system consisting of relay logic circuits, large air contactors, and speed measuring generators. After years of development, tkd-a series of hoisting machine electric control system has formed its own characteristics, however, its shortcomings are also obvious, its electrical circuit is too complicated, the system intermediate relay, electrical contacts, electrical linkage more, resulting in the hoist due to electrical faults stopping accidents continue to occur. Using plc technology of the new electronic control system have been more successfully used in mine hoisting practice, and has achieved a better operating experience, overcoming the defects of the traditional electronic control system, represents the trend of the development of electronic control technology of AC mine hoist.
