The main controller 1301 is connected to the flexible display layer 10 through the display control interface 1306, and outputs display data and control signals to the flexible display layer 10. The power module supplies power to the flexible display layer 10 through the display control interface 1306. Fig. 4 shows the structure of the flexible display layer 10. The flexible display layer comprises a transparent flexible plastic base layer 1001, an ITO transparent conductive film 1002, an organic polymer electroluminescent material layer 1003, an ITO transparent conductive film 1004 and a transparent flexible plastic surface layer 1005. The transparent flexible plastic base layer 1001 and the transparent flexible plastic surface layer 1005 are made of polyetheretherketone, polyethylene terephthalate, or Polyethersulfone (PES). And composite waterproof layers 1000 and 1006 are respectively stacked on the outer surfaces of the transparent flexible plastic base layer 1001 and the transparent flexible plastic surface layer 1005, the composite waterproof layers 1000 and 1006 refer to fig. 5, the composite waterproof layer 1000 is formed by alternately stacking a plurality of polymer layers 1000-1 and nitride layers 1000-2, the polymer layers are acrylic resin, and the nitride layers are Si3N4Preferably, each composite waterproof layer is formed by overlapping 10 polymer layers and 10 nitride layers with each other alternately. The nitride layer has stronger moisture-proof and waterproof capabilities, and the polymer layer can effectively block the micro-pore channels in the nitride layer, so that the waterproof effect in rain is enhanced. The composite waterproof layer 1006 has the same structure as the composite waterproof layer 1000. Preferably, a transparent flexible plastic substrate 1001 and a transparent flexibleThe boron fiber with the diameter of nanometer (150-500 nanometers) is uniformly doped in the surface layer 1005 of the plastic and the composite waterproof layers 1000 and 1006 on the surface of the surface layer, the mass of the doped boron fiber respectively accounts for 0.2-0.5 percent of the total mass of each base layer, the surface layer and the composite layer, the nanometer boron fiber has high strength and toughness and light weight, the nanometer diameter and the accurate control of the doping ratio of the fiber do not influence the light transmittance, the bending performance can be obviously improved, the base layer and the surface layer can still be kept flat and wrinkle-free after the folding of more than 100000 times, and therefore the waterproof performance and the light transmittance are well guaranteed.

The flexible display layer 10 with the structure has the characteristics of low manufacturing cost, suitability for large-area full-color display, low driving voltage, wide applicable temperature range, good waterproof performance, good flexibility and repeated folding resistance. As mentioned above, the flexible display layer 10 covers the outer surface of the umbrella cloth 9, and the area of the umbrella cloth 9 covering the flexible display layer 10 is transparent, so that the user can see the display content of the flexible display layer 10 from the inside of the umbrella.
The main controller 1301 connects the buzzer 1307 and the keypad 1308, so that the buzzer 1307 can be controlled to give a buzzer alarm, and user input instructions can be obtained and executed in response to a user's touch to the keypad 1308.
The multifunctional intelligent umbrella can realize the control switching of the display mode, the display content and the display brightness of the flexible display layer based on the surrounding environment state, thereby giving a prompt to a user of the umbrella on one hand, enhancing the visibility of the umbrella user in the environments of darkness, heavy rain and the like on the other hand, prompting the attention of surrounding vehicles and enhancing the safety. On the basis of hardware configuration and functions of the multifunctional intelligent umbrella, an intelligent umbrella application system is developed to realize the functions. Fig. 6 is a schematic structural diagram of the multifunctional intelligent umbrella application system applying narrowband internet of things communication. The application system comprises a distributed large number of multifunctional intelligent umbrellas U1-Un positioned at the front end of the system, an NB-IoT base station BS responsible for covering a cell, a cell server SC connected with the NB-IoT base station, and a platform server SP at the network side.
As described above, the multifunctional intelligent umbrella U1-Un can obtain the real-time position information of the intelligent umbrella through the GPS locator 1303, the ambient illuminance information of the intelligent umbrella from the illumination sensor 1304, and the ambient state information sensed by the selected type of sensor through the selectable integral sensor group 1305, for example, the multifunctional intelligent umbrella U1 of fig. 6 can sense the ultraviolet index information and the temperature information, and the multifunctional intelligent umbrella U2 can sense the humidity information, the rainfall information, and the wind speed information. Each multifunctional intelligent umbrella accesses to the cell provided by the NB-IoT base station BS through the NB-IoT communication module 1302, and uploads the real-time location information and various types of environmental status information sensed by the umbrella to the NB-IoT base station BS through a wireless uplink channel of the cell. And the NB-IoT base station BS stores the real-time position information and the environmental state information uploaded by each multifunctional intelligent umbrella in the cell in a cell server SC connected with the base station. And, the NB-IoT base station BS also sends the estimated environmental status information to the multifunctional intelligent umbrella in the local cell periodically (for example, once every five minutes) through the wireless downlink channel of the cell in a broadcast, multicast or unicast message manner. In the cell broadcast mode, the cell server SC calculates an average value of the cell environment state information as an estimated value of each type of environment state information according to each type of environment state information uploaded by each multifunctional intelligent umbrella U1-Un in the cell, and sends a broadcast message to all multifunctional intelligent umbrellas U1-Un in the cell through the NB-IoT base station. Under the multicast mode, a cell server SC divides a cell into a plurality of subareas, determines the multifunctional intelligent umbrellas located in each subarea according to the real-time position information of the multifunctional intelligent umbrellas U1-Un, takes the multifunctional intelligent umbrellas of each subarea as a group, calculates the average value of the environmental state information of the subarea as the estimated value of the environmental state information of the type according to the environmental state information of each type uploaded by the multifunctional intelligent umbrellas of each group, and sends multicast messages to the multifunctional intelligent umbrellas U1 in the corresponding group of the subarea through an NB-IoT base station. And in a unicast mode, when calculating an estimated value of certain type of environment state information, facing a certain target multifunctional intelligent umbrella in a cell, the cell server SC determines 3-5 adjacent multifunctional intelligent umbrellas which are closest to the target multifunctional intelligent umbrella and can provide the sensing value of the type of environment state information according to the real-time position information, calculates a weighted average value of the environment state information according to the type of environment state information uploaded by the 3-5 adjacent multifunctional intelligent umbrellas, and independently sends a message to the target multifunctional intelligent umbrella. For example, if the multifunctional intelligent umbrella U1 cannot sense rainfall information, it is determined that the distances between U2, U3 and U4 are closest to U1 among the intelligent umbrellas that can sense rainfall information in the local cell according to the real-time location information, and the cell server SC calculates a weighted average value according to the sensed values of the rainfall information uploaded by U2, U3 and U4:
whereinIs the weighted average, RU2、RU3、RU4the rainfall induction value beta uploaded by U2, U3 and U4U1U2、βU1U3is, betaU1U4The calculated weighted average value is a weighted coefficient inversely proportional to the distance between each neighboring multi-functional intelligent umbrella U2, U3, U4 and the target multi-functional intelligent umbrella U1, and is transmitted to the target multi-functional intelligent umbrella U1 as an estimated value of environmental status information.
For each multifunctional intelligent umbrella, the main controller 1301 obtains the ambient illumination information and the environmental status information of the selected type by using the sensor carried by the intelligent umbrella itself. For the type of environmental status information that the intelligent umbrella cannot sense itself, the main controller 1301 receives the NB-IoT base station broadcast, multicast or unicast environmental status information through the NB-IoT communication module 1302, and obtains the type of environmental status information that cannot sense itself from the broadcast, multicast or unicast message. For example, the multifunctional intelligent umbrella U1 can obtain the ambient illuminance information, the ultraviolet index information and the temperature information by using its own sensor, and can obtain humidity information, rainfall information and wind speed information which cannot be sensed by itself by receiving broadcast, multicast or unicast messages. As for the uv index information and the temperature information contained in the broadcast/multicast message, since U1 can directly sense the uv index information and the temperature information of its environment, it is not extracted from the broadcast/multicast message.
Further, the main controller 1301 determines a display mode, display content, and display brightness according to the environmental illumination information sensed by itself and the environmental status information obtained from the broadcast, multicast, and unicast messages, and outputs display data and a control signal to the flexible display layer 10 through the display control interface. For example, the main controller 1301 displays the flexible display layer as blue and slowly flashes in a sunny day according to the rainfall information and the humidity information; if the humidity is high, the flexible display layer is made to display blue and red alternately and slowly twinkle when the humidity is judged to be cloudy; if the raininess is judged through the rainfall information, controlling the flexible display layer to display red and flash rapidly; if judge through rainfall information and be heavy rain at present, then control flexible display layer and send white light to according to environment illuminance information, white light's display brightness is big when the surrounding environment is darker more, thereby plays certain illumination and increase self visibility's effect, in order to improve visibility, can also carry out the scintillation and show, in order to remind vehicle around to notice, increases user self security. In addition, characters or graphics can be displayed by using the flexible display layer 10, for example, according to the ultraviolet intensity value or the temperature value, a character prompt can be displayed on the flexible display layer 10; and displaying the current wind speed and the current wind direction on the flexible display layer according to the wind speed information.
The platform server SP on the network side is mainly responsible for registering and logging in authentication of users of the intelligent umbrellas, and the NB-IoT base station allows the intelligent umbrellas to access the cell after the authentication. The platform server SP can also push platform messages, such as traffic road condition prompts, weather early warning and even advertisements, to each intelligent umbrella through each NB-IoT base station.
In summary, the invention provides a multifunctional intelligent umbrella and an application system thereof. Compared with the existing intelligent umbrella, the invention makes a plurality of innovative improvements, including: the intelligent umbrella can be matched with various sensors of different types for sensing the environmental information, and adaptability to various application scenes expected by a user is provided. The intelligent umbrella can obtain the information pushed by the application system through the cell base station, and obtain various types of environment information which cannot be directly sensed by the intelligent umbrella, so that the intelligent umbrella is not required to be provided with all types of sensors, the cost is reduced, and various types of environment information prompt can be supported, for example, although the umbrella of a user is only provided with an ultraviolet sensor, the prompt of rainfall can be realized when the user rains. The intelligent umbrella is directly accessed to the cellular cell by adopting a low-power consumption NB-IoT communication mode. According to the intelligent umbrella, the display part of the intelligent umbrella is innovatively manufactured into the flexible display layer which covers the surface of the umbrella cloth, so that planar display is realized, the striking and visible effect of display is improved, the intelligent umbrella is easily noticed by surrounding vehicles in a heavy rain and dark environment, the display content is visible in the umbrella, and the flexible display layer has a special waterproof and folding-resistant design. In the aspect of mechanical structure, through setting up transmission post one, two integrated into one piece structures of transmission seat and transmission post, can guarantee that the umbrella stand is driving umbrella cloth and is strutting completely, and the structure is more stable, because umbrella cloth surface covering flexible display layer, thickness and hardness still need more than pure canvas umbrella face, therefore this kind of mechanical structure's support with open the effect more ideal, the problem of anti-umbrella in the time of also can not appearing the strong wind has made things convenient for people to use. The application system is designed based on an NB-IoT honeycomb architecture, can take a cell as a basic unit, takes the intelligent umbrella as a collection and sharing source of environmental information, and can also push various network messages. The invention solves the problems that the existing intelligent umbrella in the market usually has only a single function or the configuration cost of the sensor is too high, the intellectualization is not enough, the display effect is not good and the application is inconvenient.
