How to shorten the design cycle and save design costs? --Comparison of common automation design schem

For the development of an automated system, there are many development platforms that can be used. Common ideas include the following: 1. A control system with an embedded programmable chip such as a single-chip computer, DSP, etc. as the core. 2. A...

Solve the problem of analog input of the capture card

Solve the problem of analog input of the capture card

Analog input mode: (1) Differential mode: In differential mode, the DAQ device measures the differential voltage between two AI signals. as the picture shows. (2) Single-ended mode: In single-ended mode, the DAQ device measures the voltage of the AI...

Characteristics of single-ended signals, differential signals and pseudo-differential signals

Characteristics of single-ended signals, differential signals and pseudo-differential signals

1. Single-ended signal As shown in the figure, the characteristic is that a signal line is enough. The reference voltage of the reference is ground. When the voltage is greater than VH, it is 1 (high level); if it is less than VL, it is 0 (low level)...

How to choose a data acquisition card?

How to choose a data acquisition card?

Select the communication interface of the data acquisition card, that is, the interface mode. The communication method of data acquisition and computer is mainly composed of serial port (485 module, RS232), parallel port (PCI interface), USB and Ethe...

Thermocouple and RTD sensor

Thermocouple and RTD sensor

(1) Thermal resistance temperature sensor: The nature of a thermal resistance temperature sensor is a resistance that changes with temperature. As long as the resistance value of the thermal resistance is known, its ambient temperature can be calcula...

Function of data acquisition card

Function of data acquisition card

(1) The data acquisition card can be connected to external sensors. Such as temperature sensors, pressure sensors, rotary encoders, etc. Therefore, the use of data acquisition card can complete the measurement link in the measurement and control syst...
