Pump system

Abstract

Pump system with at least one pump, in particular a vacuum pump or a compressor, a controller connected to the at least one pump, wherein the controller comprises: a first processing unit directly connected to the at least one pump for providing low level services to the at least one pump, and a second processing unit connected to the first processing unit to provide high level services to the pump system, wherein the second processing unit is connectable to an external network.

1 . A pump system with at least one pump, in particular a vacuum pump or a compressor,
 a controller connected to the at least one pump, wherein the controller comprises: a first processing unit directly connected to the at least one pump for providing low level services to the at least one pump, and a second processing unit connected to the first processing unit to provide high level services to the pump system, wherein the second processing unit is connectable to an external network.   
     
     
         2 . The pump system according to  claim 1 , characterized in that the second processing unit not directly connected to the at least one pump and the first processing unit is not directly connectable to the external network. 
     
     
         3 . The pump system according to  claim 1 , characterized in that the first processing unit is configured to provide low level services by exchanging control signals with the at least one pump. 
     
     
         4 . The pump system according to  claim 1 , characterized in that the first processing unit is configured as deterministic processing unit, providing responses between 90 ms and 110 ms, preferably between 99 ms and 101 ms and most preferably 100 ms. 
     
     
         5 . The pump system according to  claim 1 , characterized in that the second processing unit is configured to provide one or more of data exchange with a cloud, an interface for controlling the pump system, security access, optimization calculation, update handling of the first processing unit as well as the second processing unit as high level services. 
     
     
         6 . The pump system according to  claim 1 , characterized in that the first processing unit is configured to reboot the second processing unit in case of failure of the second processing unit. 
     
     
         7 . The pump system according to  claim 1 , characterized in that the second processing unit is configured to reboot the first processing unit in case of failure of the first processing unit. 
     
     
         8 . The pump system according to  claim 1 , characterized in that the at least one pump comprises a sensor, wherein the sensor is directly connected to the first processing unit to transmit sensor data to the first processing unit. 
     
     
         9 . The pump system according to  claim 1 , characterized in that the at least one pump comprises a sensor, wherein the sensor is directly connected to the second processing unit to transmit sensor data to the second processing unit. 
     
     
         10 . The pump system according to  claim 1 , characterized by a fieldbus unit connected to the first processing unit or the second processing unit to provide fieldbus communication.
