Abstract

To separate a module as a description of a service from another that gains access to sensors and actuators used in the module. The present invention provides cooperated filtering with realtime and non-realtime system including a realtime system to which sensors and actuators are coupled and a non-realtime system coupled to a network, wherein processes to determine operations by the non-realtime system or the realtime system are performed by each of input processing units that process input information from the sensors coupled to the realtime system, service processing units that determine operations of the actuators on the basis of data initialized by the non-realtime system, and output processing units that prepare data used for operating the actuators.

Claims

1. Cooperated filtering with realtime and non-realtime system comprising a realtime system to which sensors and actuators are coupled and a non-realtime system coupled to a network,

wherein processes to determine operations by the non-realtime system or the realtime system are performed by each of input processing units that process input information from the sensors coupled to the realtime system, service processing units that determine operations of the actuators on the basis of data initialized by the non-realtime system, and output processing units that prepare data used for operating the actuators.

2. The cooperated filtering with realtime and non-realtime system according to claim 1,

wherein there are provided redundancy processing units that perform the processes of the input processing units and the output processing units together.

3. The cooperated filtering with realtime and non-realtime system according to claim 1,

wherein there are provided module selection units that select which of a hardware input processing unit and a hardware output processing unit realized in the realtime system and a software input processing unit and a software output processing unit realized in the non-realtime system is to be used by using parameters determined on the basis of a data size, a performance, and electric power usage necessary for the service processing units.

4. The cooperated filtering with realtime and non-realtime system according to claim 3,

wherein there is provided a status notification unit that changes each processing content of the hardware input processing unit, the hardware output processing unit, the software input processing unit, and the software output processing unit on the basis of a load status and power consumption of the realtime system or the non-realtime system in which the processing units are installed and an instruction from another computer coupled to the network.
