Definitions
- the present invention relates to a monitoring system and a monitoring method according to the preamble of claims 1 and 4, respectively.
- Data processing systems can be used for direct communication with users, as is the case with the data processing systems used in the workplace. They are used for data collection and
- Data output as well as a visualization of processes.
- Other possible uses of data processing systems are, for example, their use as control computers, control computers, process computers or data computers.
- Systems consisting of data processing systems with different, sometimes safety-relevant tasks are networked, particularly in railway engineering. These networked systems are described below as networks. In order to maintain high availability of these networks, all relevant data and processes are mapped redundantly.
- Typical configuration of a subsystem in the network to ensure relevant data and processes consists of three data processing systems, of which two data processing systems represent redundant processes and a third data processing system as a replacement
- Such networks can be monitored using functionally separate, specially designed data processing systems.
- monitoring processes have been established that are processed by the functionally separate data processing systems.
- the task of the monitoring separate data processing systems is to collect and process status information of the networked data processing systems. If necessary, measures can be initiated by the monitoring data processing systems.
- the disadvantage here is that in the event of a connection fault between the monitoring device and the network or if the monitoring device fails, the entire network is immediately without monitoring.
- the present invention is therefore based on the object of demonstrating a monitoring system for networked data processing systems so that the networked data processing systems are as highly available as possible and measures can thus be taken against detected errors.
- the system according to the invention integrates all networked data processing systems in the monitoring, so that each data processing system is assigned a different data processing system for monitoring.
- the allocation is made statically by pre-programmed memory at system start-up, but it can be changed dynamically during operation based on status information. There is therefore no need for additional functionally separate monitoring systems.
- the assignment of the monitoring tasks can be made freely among the data processing systems, since the monitoring process is identical in all data processing systems.
- the process is carried out in two stages, globally at the network level and locally at the data processing system level.
- status information of the networked data processing systems is collected from each data processing system. This can be initiated, for example, by sending a general request (broadcast).
- the data processing systems then report autonomously with their status information in compliance with a selected network protocol.
- An initiation of the process described by sending out a request can be dispensed with if the data processing systems are allowed to autonomously send status reports taking into account predefined time intervals.
- the information collected from each individual data processing system is then checked using defined criteria. These criteria are, for example, the presence or completeness or the error-free content of a status message.
- the content of a status message is not error-free if, for example, the content itself reveals an error by means of a bit pattern that is correct per se, or if the checksum of the content does not match the specifications.
- this method provides locally accurate status information of the networked data processing systems. Since all networked data processing systems are connected to the networked data processing systems.
- Another advantage is that the measures for correcting errors can be adapted to the current system status at any time, since this is known to networked data processing systems.
- Network can be summarized in physical and / or functional groups.
- the individual data processing systems can be partially or completely replaced by groups of data processing systems, the groups of data processing systems performing the same monitoring tasks as the individual data processing systems.
- 1 shows the general structure of coupled data processing systems as a network
- FIG. 2 shows the structure of coupled data processing systems which have been combined in redundant groups in order to increase the availability
- FIG. 3 shows the partial structure of data processing systems in a redundant design which are coupled directly to the network
- Figure 4 shows the internal process structure of a
- Figure 1 shows a typical structure of a network NW with networked data processing systems A to E.
- the data processing systems A to E are assigned processes PA to PE, which in practice can consist of many processes and functions.
- a monitoring system to be described further here provides that each individual data processing system A to E periodically checks itself in a first step.
- the self-assessment UA to UE u comprehends local processes for data integrity statically and dynamically as well
- FIG. 4 shows the process sequence in the data processing system A in somewhat more detail.
- An administration process VP which is functionally the same in all networked data processing systems A to E, monitors and controls a local and global monitoring method running on each data processing system A to E.
- the management process VP itself can consist of several independent processes.
- the local processes PA1 and PA2 check their own local data on the basis of global data DGA.
- the process operability and data integrity are then communicated to the administration process VP.
- the own global data DGA can be checked by the administration process become.
- a request BC can be sent to the networked data processing systems, which have to respond with their status information in definable time frames.
- the data processing system B responds with its status information ZB. All collected results of the data processing system A are in turn added to the own status information ZA.
- each data processing system A to E becomes one
- the data processing system B is responsible for monitoring the data processing system A
- the data processing system C for monitoring the
- Data processing system B the data processing system D for monitoring the data processing system C and so on. It is advantageous to ensure that a closed dependency arises when the monitoring function is assigned, in order not to risk an interruption in monitoring in the event of an error.
- the data processing system B detects an error due to the self-check UB, it will communicate this to all other data processing systems with the status information ZB.
- the data processing system C responsible for the monitoring will take the appropriate measures after receiving the status information ZB, for example by reinitializing the data processing unit B or by relocating the process PB in the network to free capacities, since this is achieved by the status information ZA to ZE are known or by other specifically suitable measures. In any case, these measures can take the error into account and a step-by-step approach is possible. If, due to an error, a data processing system can no longer perform its monitoring functions, the data processing system, which is responsible for this data processing system that is now switched off, now takes over the monitoring tasks of the defective ones
- FIG. 2 shows a typical structure of a network NW with networked data processing systems A to E, which in turn are constructed redundantly in order to obtain increased availability.
- the groups AX to EX of data processing systems in the network NW are designed as 2 of 2 systems for Example data processing system A and the redundant data processing system A2 with a reserve data processing system A3.
- two data processing systems AI and A2 perform the same functionality and in the event of a fault, one of the two can be replaced by the reserve data processing system A3.
- These groups in themselves already represent increased availability, since part of possible errors can be detected and eliminated within groups AX to EX by means of suitable internal communication IK.
- the described monitoring system makes it possible to verify other processes and data, and troubleshooting is not limited to specific data processing systems.
- the groups AX to EX perform the same functionality as in FIG. 1 the data processing systems A to E with the processes PA to PE.
- Each group AX to EX performs monitoring functions of another group AX to EX, so that in the event of a fault in a group AX to EX, processes and data can be transferred as easily as possible.
- Figure 3 shows an example of a possible network part in which the redundant data processing systems A2 and E2 and the replacement data processing systems A3 and E3 can be coupled directly to the network, so that the internal communication IK according to Figure 2 in the groups AX and EX by the described Monitoring procedure for networked data processing systems is replaceable.
- PA PA, PB, PC, PD, PE Process of a data processing system or a group of data processing systems in the network
- UE2 self-monitoring of a redundant data processing system UA3, UE3 self-monitoring of a replacement data processing system
