Detailed description of the invention
Fig. 1 is the intelligence sensor functional block diagram of invention；
Specific embodiment
The embodiment of the present invention is described more fully below, the examples of the embodiments are shown in the accompanying drawings.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.Phase
Instead, the embodiment of the present invention include the spirit for falling into attached claims and all changes within the scope of intension, modification and
Equivalent.
Intelligence sensor functional block diagram referring to Fig.1, the invention provides the following technical scheme: a kind of air compressor machine and the main electricity of water pump
Machine special intelligent sensor, including AI chip, temperature sensor, pressure sensor and vibrating sensor；The AI chip includes
MCU processing, telecommunication circuit, adc circuit and 4-20mA analogue quantity output circuit module；The adc circuit, telecommunication circuit, 4-
20mA analogue quantity output circuit module is electrically connected with MCU processor；The temperature sensor, pressure sensor and vibrating sensing
Device is connected to the adc circuit together；Integral type is made in the temperature sensor, pressure sensor and vibrating sensor, uses
One metal body is integrated.
As currently preferred, the 4-20mA analogue quantity output circuit module configuration dry contact, point three tunnels output 4-
20mA signal.
As currently preferred, the telecommunication circuit is provided with communication interface, includes RS485 and Ethernet interface, can be with
Dock Internet of Things；The RS485 uses two-wire system, further includes MODBUS-RTU agreement, which is worked using RS485.
In order to better understand the present invention, the principle of the invention is further illustrated below:
AI chip is configured, adc circuit is accessed in the signal acquisition pin of the chip, by temperature sensor, pressure sensor
It is connect with the output end of vibrating sensor with the adc circuit, the analog signals that temperature, pressure, vibrating sensor export are through ADC
Circuit conversion is digital quantity signal (current/voltage), is focused on through MCU processor, then exported by RS485 communication port,
An interface is thus only needed, it is easy for installation, reduce leakage point.Need to provide modbus address table and the communication of standard herein
Corresponding address, variable name and function description is arranged in format.
Further, as an example, the signal after centralized processing can be conveyed to by MCU processor by RS485
PLC, PLC are arranged corresponding parameter and are controlled or shown (PLC should compile corresponding program, be not described herein).It is passed with temperature
Sensor is as an example, the temperature of motor at this time is transferred to PLC by temperature sensor, if PLC only shows the temperature, that
The number can only be shown in display screen, not do any control, and pressure and the corresponding numerical value of vibration similarly, only can be aobvious
It is shown in display screen, if PLC setting control program, the temperature simulation amount of temperature sensor output carry out mould through adc circuit
Number conversion, then it is transmitted to PLC after being focused on by MCU processor, when the temperature exceeds the temperature of PLC setting, then PLC
Corresponding control (program controls portions are not described herein) is made, PLC can transmit signals to MCU processor by RS485, pass through
The output of 4-20mA analogue quantity output circuit module, if the module connects frequency converter analog input interface, PLC is become by control
Frequency device controls motor (air compressor machine, water pump), certainly, can not can also have to PLC according to field control demand.
