Description
Technical field
The utility model relates to a kind of Multi-function display units.
Background technique
The industrial instrument of tradition on the market, is shown using charactron segment encode mode, the disadvantage of numeral method mostly
It is that readability is low, man-machine interaction experience is poor, user's setup parameter needs to hold specification setting.And user carries out meter reading process
When need instrument installation site carry out meter reading, or by wiring 485 communication meter readings, for some distances farther out, installation
The measure field of operating condition complexity, user's meter reading, wiring difficulty are substantially improved, and operability is not strong.
Utility model content
The purpose of the utility model is to overcome the deficiencies in existing product, provide a kind of Multi-function display unit.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of Multi-function display unit, including primary processor, 485 sensors, Internet of Things communication module, power-supply battery, letter
Number Acquisition Circuit, hardware watchdog, button inputting circuits, 485 communicating circuits, 4-20mA signal output apparatus, relay output
Circuit, colour or monochromatic display circuit, Internet of Things communication module, power-supply battery, signal acquisition circuit, hardware watchdog, key
Input circuit, 485 communicating circuits, 4-20mA signal output apparatus, outputting circuit for relay, colour or monochromatic display circuit all with
Primary processor connection, 485 sensor connection signal Acquisition Circuits.
Signal for being wirelessly emitted to Internet of Things cloud platform by Internet of Things communication module.
Signal acquisition circuit is used to acquire the accurate data of 485 sensor measurements.
Button inputting circuits are used for parameter setting.
Outputting circuit for relay exports on-off model.
The electric current of 4-20mA signal output apparatus output is 4-20mA.
The display mode of colored or monochromatic display circuit is colored or monochromatic.
The beneficial effects of the utility model are as follows: the utility model is anti-interference extremely strong, long transmission distance, can be in any networking
Equipment reads meter information, and display interface is abundant, and man-machine interaction experience is good, applied widely.
Detailed description of the invention
Fig. 1 is the system module figure of the utility model.
Specific embodiment
The technical solution of the utility model is described further with reference to the accompanying drawings of the specification:
As shown in Figure 1, a kind of Multi-function display unit, including primary processor 1,485 sensors 2, Internet of Things communication module

Output circuit 11, colored or monochromatic display circuit 12 are all connect with primary processor 1,485 sensor, 2 connection signal Acquisition Circuit 6.
Signal for being wirelessly emitted to Internet of Things cloud platform 4 by Internet of Things communication module 3.Signal acquisition circuit 6 is for acquiring 485 sensings
The accurate data that device 2 measures.Button inputting circuits 8 are used for parameter setting.Outputting circuit for relay 11 exports on-off model.4-
The electric current that 20mA signal output apparatus 10 exports is 4-20mA.The display mode of colored or monochromatic display circuit 12 is colored or single
Color.
Working principle: the command information and signal acquisition circuit 6 that the primary processor 1 inputs button inputting circuits 8 are defeated
It is shown after the information processing entered by colored or monochromatic display circuit 12, and number will be measured by Internet of Things communication module 3
Internet of Things cloud platform 4 is accessed according to wireless issue, passes through 10 output current signal of 4-20mA signal output apparatus, relay output electricity
Road 11 exports on-off model, carries out host computer wire communication by 485 communicating circuits 9；It is connected on the primary processor 1 hard
Part house dog 7.The above circuit is powered by power-supply battery 5.
The utility model the utility model is anti-interference extremely strong, long transmission distance, can read instrument letter in any networked devices
Breath, display interface is abundant, and man-machine interaction experience is good, applied widely.
It should be noted that listed above is only a kind of specific embodiment of the utility model.Obviously, the utility model is not
It is limited to above embodiments, it can also be there are many deformation, in short, those skilled in the art can be from disclosed by the utility model
All deformations that content is directly exported or associated, are considered as the protection scope of the utility model.
