When this resistor is turned on, the steadied-wave board works on exaggerated current state, then measure and test whether conform with the design requirements. The MCU system mainly tests 10 pieces of analog signals, including 15V,24V and 48V voltages form the Z157, and 5V,±15V,±24V voltages form the Z33. In general, it is more suitable to select ADC0816 for use.
In order to automatically test multi-channel analog signals and switching signals,an intelligent testing instrument based on MSP430F149 MCU is designed.
In computer controlled digital servo system, analog quantity signal is transformed into digital signal of control system by means of sychro-to-digital converters (SDC) of integrated ZSZ-01 series.
The communicate controller was made up of ATMEGA128L and RTL8019AS, realized of technique based on embedded Internet. The communicate controller could achieve bi-directional conversion between RS232, digital signal, analog signal and Internet, and also realized remote monitoring of NC machine tool based on Web.
MC33993 is a new programmable low-power multichannel detection interface chip developed by America Motorola Company, which mainly applied in automobile electronic product. lt can not only detect automobile multichannel-switch state-variables, but also supply power for many automobile sensors, input analog signal and drive MOSFET/LED and so on.
The man-machine interface software(MMISP) is designed to configure the console software of PLS-60MeV LINAC control system. The control system is of distributed type which includes the main computerantel 310),four local stations and two sets of industrial level console computers.
In the second case, the amplitude of analog signals coming from the output of the linear amplifier is changed by the thermoresistor supplied with a heating winding.
