A multichannel multiplexed signal automatic acquisition apparatus with a manual-comparison measurement function

A multichannel multiplexed signal automatic acquisition apparatus with a manual-comparison measurement function comprises a microprocessor, a data acquisition module, a sensor interface, a communication module, a data storage module, a display module, a channel switching module and a manual-comparison measurement module. The data acquisition module, the data acquisition module, the channel switching module, the communication module, the data storage module, the display module and the manual-comparison measurement module are all connected to the microprocessor. The manual-comparison measurement module and a plurality of sensor interfaces are all connected to the channel switching module. The sensor interfaces are used for connecting to a vibratory string type sensor, a differential resistance type sensor, a voltage signal sensor and an RS485 signal sensor. Sensor signals are input to the channel switching module through the sensor interfaces. After the channel switching module selects on-off, the sensor signals are connected to a corresponding sensor reading instrument via the manual-comparison measurement module. According to the utility model, problems of a unitary acquisition form, a relatively small number of channels and low intelligent degree of engineering monitoring equipment are solved, and characteristics of high reliability, function strong and high efficiency are realized.
