| Abstract: | The data acquisition system was introduced which was composed of AT89C52, RAM, AD574, power circuit, analog quantity input acquisition module, etc. The 8 ways data acquisition system was realized by using 12 bits high-precision parallel A/D converter chip AD574 and 8-channel fault protection analog switch. The serial real-time clock chip was used to record the time that data appeared. The data acquisition system is suitable for a variety of onsite automatic monitoring and control, with stable performance, high reliability, fast response and so on. |
