Abstract: A data collecting system includes a management server, a number of data collecting chains. Each data collecting chain includes a computer connected to the management server, at least one sensor and a data acquisition (DAQ), coupled to the sensor(s) and connected to the computer through RS485, configured to acquire sensing data from the sensor(s) and transmit the sensing data to the computer. The DAQs are connected to the computers through a wireless backup transmission interface. The management server sends a first confirmation signal to the computers. When at least one of the computers does not respond to the first confirmation signal, the management server indicates the computers which have responded to the first confirmation signal to receive the sensing data from the DAQ(s) corresponding to the computer(s) which doesn't respond to the first confirmation signal through the wireless backup transmission interface.

Abstract: Remote monitoring systems for remotely monitoring execution status of a PLC (Programmable Logic controller) program of a machine include a storage module, a parameter retrieval module and a monitoring module. The storage module stores ladder diagram information corresponding to a PLC source program, wherein the ladder diagram information includes PLC signal address relation information, a plurality of logic switches and a responsive collect command of each logic switch of a ladder diagram. The PLC signal address relation information indicates the relations of the logic switches on the ladder diagram. The parameter retrieval module respectively retrieves parameter data corresponding to the logic switches using the responsive collect commands. The monitoring module generates a status of ladder diagram according to the logic switches, the parameter data and the PLC signal address relation information to display the parameter data corresponding to each logic switch when the machine is executing the PLC source program.

Abstract: A monitoring system applied to a shaping machine having a high speed electricity meter. The monitoring system includes a current obtaining device and an analyzing device. The current obtaining device is coupled to the high speed electricity meter to obtain a plurality of current signals from the operated shaping machine and in respond to the shaping machine executes a machining program, the current obtaining device extracts current variation data from the current signals. The machining program corresponds to a piece of the current variation data. The piece of the current variation datum comprises a maximum current and an occurring time that the maximum current being recorded. The analyzing device is configured to calculate a gap, based on the maximum currents and the occurring times corresponding to at least two successive machining programs. In respond to the gap time exceeding a predetermined threshold, the analyzing device generates a warning signal.
