Abstract
The present invention relates to a kind of remote data acquisition device for supporting Modbus protocol-intelligent instrument, wherein, including signal modulator, A/D converter, RS485 modules, microprocessor, GPRS module and police guard at as entrance's circuit module, wherein, signal modulator, A/D converter, RS485 modules, microprocessor and GPRS module are sequentially connected, police guard at as entrance's circuit module connection microprocessor；By connecing the RS485 interfaces of intelligence instrument are relative with collector, the remote server that the instrumented data signal collected is transmitted by GPRS module after treatment；Possess police guard at as entrance's alarm function, current situation can be recognized in time for controllers by the mobile phone of alarm short message sending to controllers when alarm occurs.The huge investment for setting up wireless network can be eliminated, and transmission short message is also relatively cheap at present, and the stability and real-time of transmission can also be ensured.
Description
Technical field
The present invention relates to data acquisition technical field, more particularly to a kind of support Modbus agreement intelligence based on GPRS
The remote data acquisition device of energy instrument.
Background technology
The intelligence instrument of Modbus agreements is supported to be applied in fields such as Industry Control, power communication, petrochemical industries in recent years
It is more and more.It is all live meter reading that current instrumented data inquiry mode is most of, is copied using the transmission of remote signal
It is also fewer that table is counted；Some are to utilize common telephone wire, and also some are to utilize power transmission line, but use both
Method controllers not at the scene when can not understand the running situation of system in real time, while using the mode of wire transmission
Wiring and maintenance are all relatively difficult；The problem of this respect being solved using wireless GPRS technology.
So, how to design a kind of Wireless data acquisition unit of wireless GPRS, the problem of currently being solved as us.
The content of the invention
Present invention aim to address appeal problem, there is provided a kind of teledata for supporting Modbus protocol-intelligent instrument

RS485 modules, microprocessor and GPRS module are sequentially connected, police guard at as entrance's circuit module connection microprocessor；
By connecing the RS485 interfaces of intelligence instrument are relative with collector, the instrumented data signal collected leads to after treatment
Cross the remote server of GPRS module transmission；Possess police guard at as entrance's alarm function, can be by alarm short message sending to control when alarm occurs
On the mobile phone of personnel processed, current situation is recognized in time for controllers.
Further, described microprocessor model is STM32F103.
Further, described RS485 modules use MAX485.
Further, described GPRS module supports GSM and CDMA2000 network formats, the communication module type used simultaneously
Number be SIM800C and SIM2000C.
The beneficial effects of the invention are as follows：
Using GPRS technologies, the huge investment for setting up wireless network can be eliminated, and transmission short message is also relatively cheap at present,
The stability and real-time of transmission can also be ensured, so the system has the reality in Industry Control, power communication, petrochemical industry etc.
When monitoring in terms of there is very high promotional value.GSM and CDMA2000 network formats are supported simultaneously, and aspect selection is most suitable
Virtual network operator.
