Abstract

A system is described for monitoring an industrial cleaning process or machine. A plurality of operating devices are used for controlling the process or operation of the machine. The system comprises a processing unit and a plurality of sensors for sensing operating parameters of the process or machine. The sensors provide parameter dependent signals to the processing unit. At least one set of at least two sensors sensing mutually dependent parameters is provided and the processing unit is programmed with at least one algorithm using as input signals the parameter dependent signals of a set of sensors sensing mutual dependent parameters. The algorithm comprises an alarm setting for at least one of the input signals and this alarm setting is activated by at least the other input signal. The processing unit generates an alarm message if the input signal matches the alarm setting

Claims

1. System for monitoring an industrial cleaning process or machine, wherein a plurality of operating devices are used for controlling the process or operation of the machine, the system comprising a processing unit and a plurality of sensors for sensing operating parameters of the process or machine, the sensors providing parameter dependent signals to the processing unit, characterized in that at least one set of at least two sensors sensing mutually dependent parameters is provided, and in that the processing unit is programmed with at least one algorithm using as input signals the parameter dependent signals of a set of sensors sensing mutual dependent parameters, wherein the algorithm comprises an alarm setting for at least one of the input signals, said alarm setting being activated by at least the other input signal, wherein the processing unit generates an alarm message if said one input signal matches the alarm setting.

2. System according to

claim 1

, further comprising a timer means, wherein at least one algorithm uses a time signal as one of the input signals or as a further input signal, wherein the alarm setting depends on the time dependency of an input signal.

3. System according to

claim 1

, wherein the processing unit is programmed to make a connection to a service centre computer in case of an alarm message and to send the alarm message to the service centre computer.

4. System according to

claim 1

, wherein the processing unit is programmed to make a connection to a service centre computer if, when an alarm message was sent to the service centre computer, the corresponding input signal does not match the alarm setting anymore and to send a message “

alarm cancelled”

to the service centre computer.

5. System according to

claim 1

, wherein the service centre computer is programmed to send a control signal to the processing unit from which an alarm message was received, wherein the processing unit actuates an operating device to correct the alarm situation.

6. System according to

claim 1

, wherein the processing unit provides an alarm message including a process or machine identification, an alarm identification and time/date of occurrence of the alarm message.

7. System according to

claim 1

, comprising an alarm signalling device, wherein the processing unit is programmed with at least one algorithm also causing the processing unit to actuate the alarm signalling device if the input signal matches the alarm setting.
