It illustrates below in conjunction with the accompanying drawings：
In Fig. 1, there is APP intelligent control temperature-sensitive advertisement umbrella schematic diagrames, the umbrella is by solar panel, heating plate, temperature
The components such as controller, lithium battery, intelligent terminal are constituted.
Solar panel on umbrella cover can provide electric energy for entire temperature-control discoloring circuit, and after energization, heating plate can be to umbrella
It is heated in face.Intelligent terminal is controlled by bluetooth connection mode, to entire heater circuit into trip temperature.When the Temperature Quantity of variation
When reaching the temperature spot of temperature sensing material discoloration of umbrella cover coating, umbrella cover color changes, to make umbrella cover pattern become
Change.When solar panel not enough power supply, electric energy supplement can be carried out by the lithium battery built in umbrella handle, to realize solar energy
With the complementation between lithium battery energy, to meet the needs of temperature sensing material temperature change.
Fig. 2 shows, when temperature becomes from pattern when changing to 40 degrees Celsius of this room temperature variation ranges for 20 degrees Celsius
Change situation.When temperature reaches 20 degrees Celsius, the pattern of McDonald is presented；Circuit works on, when temperature rise is Celsius to 25
When spending, temperature sensing material color changes, McDonald's pattern loss, and KFC pattern is presented in umbrella cover；When circuit continues to heat, reach
When to 30 degrees Celsius, due to the intrinsic temperature-sensitive characteristic of temperature sensing paint, color continues to change, and will present out other enterprises
LOGO。
Patent of the present invention shows only three kinds of change in pattern of the temperature-sensitive advertisement umbrella with APP intelligent controls, but this hair
Bright patent can continue to replicate the advertisement umbrella for being expanded into multicolor pattern variation, be allowed to realize the more abundant reality of color pattern
Border advertisement applications scene.
It is and how temperature to be realized by intelligent terminal about between solar panel of the present invention and lithium battery below
Control, to realize advertisement umbrella cover pattern variation specific implementation circuit design.
As shown in figure 3, using microcontroller as bottom kernel control module, realize that temperature is examined by digital temperature sensor
It surveys；It is modulated by its PWN to be controlled into trip temperature；And be attached with bluetooth module using serial ports, to realize APP to circuit temperature
The control function of degree；And each passage temperature is transmitted by bluetooth, and temperature display is carried out by display device, with clear not equality of temperature
The pattern presented when spending is different.
It is APP intelligent temperature control circuit design of Simulation figures shown in Fig. 4.Microcontroller U1 is powered on first, and by its
The power supply and normal off of respective pins and relay, normally opened control terminal are attached.Because the design invention needs to change three group pictures
Case changes, therefore uses three groups of heater circuits, and controls the temperature of three groups of circuits, so using four tunnel relay module,
Another way is used for controlling the break-make of integrated circuit.
Three DS18B20 are the temperature sensor of three groups of heater circuits.When circuit works and is heated, temperature sensing
The continuous monitoring temperature variation of device, and the temperature of current heater circuit is shown by display device, to learn current temperature
Whether degree reaches the condition of temperature sensing material color change.
As shown in Figure 7：U2, U3, U4 are respectively the temperature sensor on three groups of heater circuits, on current heater circuit
Heating film into trip temperature detection, and by data feedback to microcontroller.
As shown in Figure 8：RL1, RL2, RL3, RL4 are control device --- the relay of heater circuit.
RL1 is that lithium battery is switched with solar cell for supplying power switching control, when electric quantity of lithium battery deficiency, can pass through APP
Control RL1 switches to solar powered, also can switch to battery powered from solar energy.
RL2, RL3, RL4 are respectively the control switch of three groups of heater circuits.
When the temperature that first group of temperature sensor detects is insufficient to allow temperature sensing material color to change, relay connects
Logical, circuit continues to heat, when the temperature data of temperature sensor feedback is enough that temperature sensing material color is made to change, relay
It disconnects, circuit stops heating, and the first width figure color change pattern changes.
Continue to heat to second group of circuit at this time, when the temperature data of temperature sensor feedback is enough to make temperature sensing material color
When changing, relay disconnects, and circuit stops heating, and the second width figure color change pattern changes.
Third group circuit is still in continuous heating at this time, when the temperature data of temperature sensor feedback is enough to make third group temperature-sensitive
When material color changes, relay disconnects, and circuit stops heating, and third width figure color change pattern changes.
P1 is bluetooth module, is communicated with microcontroller by serial ports.It is carried out on the APP of the intelligent terminal write
Corresponding operating, you can make relay carry out connecting and disconnecting, to realize the through and off of circuit, and then change umbrella cover temperature, make
Umbrella cover pattern changes.
The design invention only lists three groups of heater circuits and three groups of change in pattern, but heater circuit and the figure of variation
Case, which can infinitely extend, is extended to multigroup heating module and multiple patterns variation, is allowed to that more abundant pattern level is presented
Variation.
Fig. 5 is system circuit design schematic diagram, illustrates the theory structure of entire circuit, using which component, and
Connection type between each component, to realize circuit power conversion and temperature controlled function.
Fig. 6 is that PCB design domain and PCB circuit board design and produce domain, and for the design and fabrication of whole system, provide must
It will foundation.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
