Definitions

  • the invention relates to a computing system and a method for the maintenance of a plant for the production of goods, preferably in the food and beverage industry, e.g. a coffee roaster.
  • the invention is based on the object of developing a computational system and a method for the maintenance of such a system, by means of which on the one hand the technical-economic outlay for the maintenance of the system can be reduced, and furthermore an increase in the availability of the system is to be achieved. Both operational reliability and process reliability of the system should be guaranteed; The desired process should also be designed as flexibly as possible, leaving a lot of room for innovations, and thus simplifying the future-oriented of the plant as a whole.
  • a computing system is to be specified that not only enables plants in the food and beverage industry for which it is particularly suitable, but also other plants to optimize and bill for the maintenance of industrial plants. In particular, success-based billing of maintenance should be possible.
  • the specification of the computing system is the overarching task of the invention, while the method for maintenance is a special task.
  • the overall task is carried out according to the wording of the
  • Claim 1 solved.
  • a relative database ie a database in which changes in a position are adopted in all areas of the database, means that a database form that is particularly suitable for solving the task is selected. It is ensured that the information about the system, system components and their individual parts is always up to date.
  • Such databases are already known per se, their use for the maintenance of a system is particularly advantageous.
  • the use of a main tool is also known in computing technology, e.g. in the form of the program “Navision ⁇ .
  • a program such as the Navision program in the form of a relational database together with other system-specific tools has been combined to form a software tool that, in combination with a suitable business model, enables optimal maintenance of a system, particularly in the food and beverage industry.
  • the computing system has a system model in list form for, machines and machine parts in the relational database, which is constructed, for example, according to SAP specifications. This makes it possible to work with software that is widely used in the industrial sector and that includes all the individual parts of a system. The commercial side of plant management and logistics can also be included in maintenance with this program. Overall, there is a new, fully functional system with software combined in a new way.
  • the computing system is designed to work with standardized data on the usability, utilization and consumption of the machines. It also contains lists of service life and lists for the maintenance measures required, depending on the service life of machines and the actual operating times. This creates a list of the system status from which the necessary measures, reorders etc. can be generated.
  • the main tool is advantageously designed for the special handling of individual trades, the measures for the individual trades being entered into the main tool in a task-specific manner. This is how maintenance is organized in a new way.
  • the computing system contains illustrations of the maintenance processes in list form. It is particularly advantageous for the system to be operated by people who do not need to overlook the individual logical processes in the system.
  • the use of the relational database ensures that the individual maintenance processes are also shown in the lists in which they have not been recorded. Overall, this always results in an up-to-date picture of the maintenance processes.
  • the system for handling the maintenance processes is set up on the basis of electronic order cards that can be displayed.
  • the order cards form the basis of the individual maintenance processes and are particularly securely controllable.
  • the maintenance processes themselves are processed using flow charts that are computationally constructed and do not need to be shown.
  • the computer system Since the computer system is also used for billing while recording the actual machine stress, it advantageously has machine-operated operating data terminals or machine sensors for data acquisition. So there is an objective basis for accounting and behavioral prediction.
  • the individual operating data terminals or the machine sensors can also be carried out by means of corresponding detections in a plant control system, if such exists. Data from individual machines, machine groups and the entire system are recorded and output. If, as is so often the case, the system only has machine groups networked with funds (stand-alone operation), which, moreover, often come from different manufacturers and are of different ages, the system control system will only collect data for which it is accessible. The rest of the data is recorded by the operating data terminals or by records from the supervisory staff. Overall, however, there is a comprehensible basis for the billing and forecast data.
