Abstract

A server in electronic communication with at least one data acquisition unit via a wireless receiver. The server measures energy consumption and productivity of a machine. The machine is installed with a current analyzer and a detection unit, and wirelessly connects to the at least one data acquisition unit. The current analyzer measures the energy consumption of the machine. The detection unit calculates the productivity of the machine. After a search command is sent to the wireless receiver, a usable data acquisition unit collects the energy consumption and the productivity of the machine. The server analyzes the energy consumption and productivity of the machine and generates an analysis chart. The analysis chart is displayed on a display screen.

Claims

1. A server in electronic communication with at least one data acquisition unit via a wireless receiver, the server comprising:

a sending module operable to send a search command to the wireless receiver to search a data acquisition unit near a machine, and send a data collection command to the wireless receiver to obtain energy consumption and productivity of the machine collected by the data acquisition unit;

a receiving module operable to receive the energy consumption and the productivity of the machine, and convert data format of the energy consumption and the productivity of the machine;

a data transmission module operable to transmit the converted energy consumption and productivity of the machine to a database;

an analysis module operable to analyze the converted energy consumption and productivity of the machine to generate an analysis chart; and

a displaying module operable to display the analysis chart on a display screen of the server.

2. The system as claimed in claim 1, wherein the at least one data acquisition unit is wirelessly connected to the machine installed with a current analyzer and a detection unit.

3. The system as claimed in claim 2, wherein the current analyzer uses an energy consumption calculation unit to measure energy consumption during predetermined intervals of the machine, and accumulate the energy consumption measurements of the machine of each interval to obtain a total energy consumption of the machine.

4. The system as claimed in claim 1, wherein the detection unit uses a counter to count the number of items produced or manufactured by the machine, to obtain the productivity of the machine.

5. The system as claimed in claim 1, wherein the wireless receiver is connected to the data acquisition unit via a router.

6. The system as claimed in claim 1, wherein the data acquisition unit stores a correction parameter for correcting the energy consumption of the machine.
