The communication module of wired mode adopts RS-232 or RS-485 or CAN or Ethernet.
The communication module of wireless mode adopts ZigBee or GPRS or CDMA.
The major function of notebook data acquisition controller is to carry out the collection of analog input signals collecting, on-the-spot Modbus instrumented data, and sends to the center by communication module.Module itself can be set to arbitrarily main frame and slave mode, and can switch wireless communication modes.Module also can directly use RS-485 isolation communication interface to use as wired acquisition module.Module has 4 tunnel AI differential path, and each group differential path also can be configured to 2 tunnel single-ended input channel, to satisfy different occasion demands, is applicable to gather the various voltage and current signals of industry spot, and sampling resolution is 12; Module also has analog output, digital quantity input and digital output subsidiary function.Module has 2 tunnel analog output channel, can independently control output, also can export synchronously, and output resolution ratio is 12; Module also has 8 road DI and 8 road DO passages.Module has also possessed the collection that two-way thermal resistance input interface can be realized scene temperature in addition.
Acquisition controller is achieved as follows function:
1. the collection of in-site modeling signal
System possesses the AD converter of isolation, directly the analog voltage/current signal (1-5V/0-10V/4-20ma) of measure field instrument, sensor and transmitter output.Can directly measure two-way two line thermal resistance signals.Also making the Modbus agreement on communication protocol, is that each road AD input all possesses independent register address, and the user just can gather by the data of Modbus agreement to instrument like this.System can be set to single-ended and the difference input pattern is accepted respectively on-the-spot single-ended and differential analog signal.
2. the data acquisition of field digital instrument
System possesses the RS-485 interface, can realize communicating by letter of RTU and on-the-spot Modbus instrument, directly can carry out reading of data by the Modbus agreement.
3. the output of the I/O of switching value
The I/O output of switching value can realize that the detection of external unit switching signal output reaches the control function to external unit, all input and output amounts are all hinted obliquely at the register for Modbus, use the mode of reading the Modbus register to realize to the collection of input signal amount, adopt the mode of writing the Modbus register to realize to the control of peripherals.
4. analog output
