DOSAT H04 is an integral automatic control system for the production and sales management of premixed concrete in cyclical operation gravimetric plants. This system is a tool that guarantees to obtain an stable quality in the production of premixed concrete, and also to control the material resources and invoicing issues of the company. The system is implemented on a PC with Windows98, Windows Me, Windows NT 4.0, Windows 2000 or Windows XP using a TCP/IP protocol for data transmission.

DOSAT H04 is modularly designed so that it can be installed in companies with one plant or more than one plant, covering from the placing of the order, the automatic control of concrete production, inventory control of raw materials, transportation, up to the invoicing to the client. In the case of companies with more than one plant the system includes:

• Weighing system: formed by string gates, manual control desk, and measuring terminal. • PC and control software: the computing system presents an intuitive and easy to handle graphic interface that allows to introduce an unlimited amount of recipes, and strong and efficient control program with three types of controllers including a PID, compensation of humidity, etc. • Global Orders Module: this software attends the creation of contracts of Global Orders that are to be sent to the production plants or to the dispatcher via e-mail, internet, intranet, floppies, etc. • Daily Orders Module: this software was designed for companies with a dispatcher who divides Global Orders into Daily Orders and distributes them among the different Plants according to their geographical location, production capacity, etc. • Reporting and Invoicing Module: this software receives information from the different plants and issue more than 90 reports itemized as Production Process Reports, Raw Material Reports, General Transportation Reports, and Client Invoicing Reports.

For companies with only one plant:

In this case the software of control undertakes the functions of the other programs, thus providing all the necessary reports, including the client invoicing information.

Since 1998, with this system 18 plants have been installed in Cuba obtaining the following advantages:

• Quality stabilization of concrete production • A more rational use of labor • Reduction in human errors • Increase in the production rate of the plant • Increase of operation hours between maintenance stops • A more strict control of the resources • Reliable and up-to-date invoicing of the concrete production
