Patent ID: 8175818

Claim:
A device for monitoring one or more values of an environmental parameter of an environment surrounding a system, the device comprising: a sensor to measure said values; a circuit for transmitting said values; a processing unit comprising a microprocessor and a program memory for receiving said values, and processing said values in order to determine a percentage of consumed life of the system, the percentage of consumed life being the result of the environment to which the system is subjected; a means for transmission, in real time, of said values to the processing unit; wherein the processing unit further comprises: a means for simplifying the transmitted values to provide simplified values, a means for determining cycles based on the simplified values to provide determined cycles, and a means for calculating, in real time, the percentage of consumed life of a system, from the determined cycles, the means for calculating comprising: a preconfigured memory comprising a faulty cycle matrix for converting the determined cycles into a deterioration value from the number of faulty cycles contained in said faulty cycle matrix, the preconfigured memory composed of lines wherein addresses of the lines represent average values of the cycle and columns wherein addresses of the columns represent differences in extreme values forming the cycle, the intersection of the lines and the columns supplying a number of faulty cycles, convertible to deterioration values of the cycle, which is opposite to the number of faulty cycles, a means for adding up deterioration values to provide a total, and a means for at least one of warning, interpreting, or alarming, according to the total.
