Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Such as accompanying drawing 1, liquid level long-distance intelligent measurement apparatus, including liquid level sensor, power supply, data acquisition controller and PC
End, the power supply connect with data acquisition controller power supply, the signal output part and data acquisition control of the liquid level sensor
The signal input part connection of device, the signal output part of the data acquisition controller are connected with the signal input part at PC ends.
Data acquisition controller is integrated with level gauging pick-up plate, data acquisition/processing module and gsm module this 3 masters
Want module.The signal that pick-up plate transmits liquid level sensor is converted to the simulation of the rs 232 serial interface signal or 4-20mA of number format
Signal.After data processing module is responsible for the data processing that collects pick-up plate, sent via gsm module to server, so as to
Complete acquisition tasks.
Sent specifically, the data acquisition controller includes RC-LED01DR type pick-ups plate, data processing module and GSM
Module, the signal output part of the liquid level sensor are connected with the sensor interface input of RC-LED01DR type pick-up plates, institute
The transmitter communication interface data transmission of the RS485 interfaces and the data processing module of stating RC-LED01DR type pick-up plates connects
Connect, the signal output part of the 4-20mA interfaces of the RC-LED01DR types pick-up plate and the Data Detection of the data processing module
The signal input part connection of process circuit, the GSM of the gsm communication interface of the data processing module and the GSM sending modules
Communication interface data transmission connection, the GSM sending modules are connected by GSM receiving modules and the transmission of PC end signals.
Further, power supply is 12-36VDC power supplys, the 12-36VDC power supplys respectively with RC-LED01DR type pick-up plates
Power interface, data processing module power supply circuit DC-DC power supply connection, the power supply circuit DC-DC and GSM
Sending module power supply connection；The PC ends connect with the power supply of GSM receiving modules.
According to demand, 2 versions are designed：RS485 interfaces version and 4-20mA interface versions.Respectively such as the institute of accompanying drawing 2 and 3
Show.RS485 interface boards passed through 485/TTL level shifting circuits to the rs 232 serial interface signal of transmitter originally, and being converted to processor can locate
The data signal of the Transistor-Transistor Logic level of reason, processor send the data collected to server via gsm module.4-20mA connects
Mouth version passes through high-precision 4-20mA change-over circuits to the 4-20mA analog signals of transmitter, is converted to 0-5VDC simulation letter
Number, then unipolarity analog signal is converted into corresponding data signal, the data that processor will collect via high-precision adc
