The utility model has the advantages that: by applying the TFT serial port color screen, the user experience of the gas ultrasonic flowmeter is improved, and meanwhile, the investment of production enterprises is reduced.
Description
Technical field
This utility model belongs to flow measurement technology field, particularly relates to a kind of gas ultrasound ripple transducer applying serial ports color screen.
Background technology
At present, field of flow meters at home, segment code type liquid crystal display screen is widely used because of the advantage having price low, low in energy consumption.But the technical field of electronic equipment TFT color screen at other high speed developments such as mobile phone, computer is commonly used already.
Current industry dog-eat-dog, effusion meter demand is gradually increased, and releases high-performance timely, the product of low cost is the most important thing.By contrast, segment code type liquid crystal shortcoming gradually highlights: color is single, and resolution is low, and outward appearance is the most attractive in appearance；R&D cycle is long, and human input is big；Need the higher MCU of dominant frequency to drive, add hardware cost；Complicated with the connection line of MCU, interference free performance is poor；Trouble shoot difficulty is big, complex operation.
Such as some industry spot, because there is Electricity Generation equipment, the duty of effusion meter is more vulnerable to interference, now liquid crystal display screen and the most distances of MCU control signal wire are the biggest, liquid crystal is easily disturbed, and the problems such as colored screen flash screen even cannot start occurs, once goes wrong, the workload that line fault is got rid of is big, operation complexity.
Utility model content
The problems such as this utility model is complicated for current segment code type liquid crystal display weak effect, circuit, be easily disturbed, a kind of gas ultrasound ripple transducer applying serial ports color screen is provided, by application TFT serial ports color screen, improve the Consumer's Experience of Ultrasonic Wave Flowmeter, reduce every input of manufacturing enterprise simultaneously.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of gas ultrasound ripple transducer applying serial ports color screen, it is characterised in that include that TFT color screen system and flowmeter system, described TFT color screen system are connected by connection with described flowmeter system.
Described TFT color screen system includes that power circuit, controller, LED power process circuit, internal memory, clock, display screen, described power circuit is connected with described controller, described LED power process circuit, described internal memory, described clock respectively, described controller respectively with described LED power process circuit, described display screen, described Memory linkage, described clock respectively with described controller, described Memory linkage.
Described flowmeter system includes that power-supply system, MCU, described power-supply system are connected with described MCU.
Described power-supply system is connected with described power circuit, and described MCU is connected with described controller.
Described power-supply system provides the voltage of 5V to described power circuit.
The beneficial effects of the utility model are: TFT color screen, from tape controller, i.e. need not send parsing data from MCU by data wire, both reduced the workload of MCU, and decreased the programming amount of this functional module, shorten the R&D cycle；Using Transistor-Transistor Logic level and the connected mode of two line communications, enormously simplify the connection between display screen and MCU, make PCB fabric swatch more rationally efficiently, capacity of resisting disturbance is strong.Power-supply system is that power supply processing circuit provides 5V DC voltage, it is to avoid voltage surge fluctuation and the risk of noise jamming, makes the out-put supply more stable effectively.LED power processes circuit part can realize 64 grades of brightness by instruction, so that display screen color is more rich, it is easy to distinguish different parameters.It is the most attractive in appearance that this utility model makes often to show screen display parameter, improves MCU work efficiency, and reduces purchase cost, and trouble shoot simple possible is easy to use, simple to operate.

Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of detailed description of the invention of the present utility model is explained.
As it is shown in figure 1, this utility model provides a kind of gas ultrasound ripple transducer applying serial ports color screen, including TFT color screen and flowmeter system, described TFT color screen is connected by connection with described flowmeter system.Described TFT color screen includes that power circuit 1, controller 2, LED power process circuit 3, internal memory 6, clock 7, display screen 8, described power circuit 1 is connected with described controller 2, described LED power process circuit 3, described internal memory 6, described clock 7 respectively, described controller 2 is connected with described LED power process circuit 3, described display screen 8, described internal memory 6, and described clock 7 is connected with described controller 2, described internal memory 6 respectively.
Described flowmeter system includes that power-supply system 4, MCU5, described power-supply system 4 are connected with described MCU5.Described power-supply system 4 is connected with described power circuit 1, and described MCU5 is connected with described controller 2.
Described power-supply system 4 provides the voltage of 5V to described power circuit 1.
Operation principle: effusion meter power-supply system exports 3.3V DC voltage to MCU5, exports 5V DC voltage to TFT color screen system, it is ensured that whole flowmeter system and TFT color screen system worked well；The power circuit 1 that TFT color screen system comprises processes circuit 3, internal memory 6 and clock 7 to controller 2, LED power and exports 3.3V DC voltage, it is ensured that working power needed for controller 2.It is mutual that MCU5 carries out data message by two connections and controller 2, the signal received is sent to LED power by processor and processes circuit 3, internal memory 6 and display screen 8 by controller 2, LED power processes circuit 3 according to the signal received, control the change of LED luminance, thus reach the function of colored display.
Fig. 2 is this utility model TFT color screen circuit theory diagrams.In Fig. 2 U33 be the MCU of flowmeter system, P10 be TFT color screen module.The two is connected by two connections, i.e. 57 feet of U33 connect 3 feet of P10 as the MCU data sending terminal TX to TFT color screen module；56 feet of U33 connect 2 feet of P10 as the MCU data receiver RX to TFT color screen module.Additionally 4 feet of P10 are TFT color screen module for power supply end, connect+5V DC voltage, 1 foot ground connection.
