More Information
Summary:An intelligent test platform of an analysis device based on site programmable peripheral chips includes a single-chip processor, a PSD and a ROM connected with the PSD via the system bus, the PSD realizes input and output devices to outboard and is connected with data collection module, which is an A/D converter, the input of which is connected with a data collection channel, the output of A/D converter controls the port to connect with PSD and expand input/output port, a remote communication on-line monitor module, the analog volume trend output circuit generates PWM signal and HSO signal from the single-chip processor and outputs 4~20mA trend output via high frequency photoelectric isolation and v/2 conversion circuit to realize the control to the output by regulating the duty ratio.
