All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Consider that an elderly person needs to be quickly located to a specific location after falling. At present, the positioning modes mainly include GPS positioning, UWB positioning, WIFI, bluetooth, RFID, Zigbee positioning, and the like. The GPS positioning is mainly applied to outdoor positioning, indoor positioning is easily affected by buildings, and the precision is very low; the UWB positioning precision is higher, but the price is very expensive and the cost is higher; the application provides an indoor falling detection wrist guard device which comprises a wrist guard body, a flexible battery, a falling detection component, a processor and a LoRa positioning communicator, wherein the falling detection component, the processor and the LoRa positioning communicator are respectively arranged in the wrist guard body; the fall detection assembly comprises: at least one acceleration sensor and at least one barometric pressure sensor; acceleration sensor, baroceptor, flexible battery, loRa location communicator respectively with communication connection between the treater, can realize wearing personnel's tumble detection and location to the wrist band that is located indoor scene, can effectively improve wearing personnel and when accuracy and the precision that detects and fix a position tumble indoor, effectively reduce tumble detection and positioner's setting and application cost, the device has characteristics such as low power dissipation, and is with low costs, wide coverage, can accurately detect the condition of tumbleing, and fix a position indoor concrete position fast, make the early warning, and through using great flexible battery, make the device wear the comfort level good, the electric quantity is sufficient and the stand-by time is of a specified duration, satisfy the long-time user demand of old person.
In one or more embodiments of the present application, the processor may specifically be a single chip Microcomputer (also referred to as a MCU), and the number of the single chip Microcomputer may be an existing single chip Microcomputer model, such as an STM32F4x9 and an STM32F401 in a Kinetis L series MCU set, a new ARM Cortex-M0+ processor, an EFM32Giant Gecko, a JZ4775, an SC7710, and a Cortex-M4.
In one or more embodiments of the application, the flexible battery may be one of a flexible lithium ion battery or a flexible solar battery, and the flexible lithium ion battery and the flexible solar battery may also be used simultaneously, so as to further improve the power supply reliability of the indoor fall detection wrist guard device.
It can be understood that the flexible lithium ion battery is a bendable lithium ion battery, and the working principle of the flexible lithium ion battery is the same as that of the lithium ion battery, but the flexible lithium ion battery uses a flexible current collector, so that the flexible lithium ion battery exhibits flexibility, and the characteristics of bending and stretching, so that the flexible lithium ion battery can be used as a power source of the indoor fall detection wrist protection device. In one example, the flexible lithium ion battery may be composed of various conductive current collectors (e.g., carbon nanotubes, graphene, carbon cloth, etc.).
In addition, the flexible solar cell may be made of amorphous silicon, copper indium gallium selenide, an organic semiconductor, or dye sensitization. In one example, the amorphous silicon three-junction laminated cell structure comprises three p-n junction absorption layers with different band gaps, and the top cell absorbs blue light by using amorphous silicon a-Si with a band gap of 1.8 eV. The intermediate cell uses silicon-germanium alloy a-SiGe with a band gap of 1.6eV, green light is absorbed, and the content of Ge is 10% -15%. The bottom cell uses silicon germanium alloy a-SiGe with 1.4eV band gap, which absorbs red light and infrared light by 40% -50% and has higher Ge content. After sunlight sequentially passes through the three semiconductor absorption layers, a part of light which is not absorbed is reflected by the Al/ZnO back reflection layer and returns to the three semiconductor absorption layers, the absorption process is carried out again, and the back reflection layer plays a role in light trapping. Therefore, the amorphous silicon flexible battery can absorb incident light more effectively, improves conversion efficiency and output power, and has better performance under the conditions of low incident light and scattered light.
In one or more embodiments of the present application, the LoRa positioning communicator may be specifically an LoRa chip, and the LoRa chip may be an existing LoRa core model, for example, a model such as sx1272 to sx1279 may be selected according to a difference of an operating frequency band and a spreading factor. The specific mode of the LoRa positioning communicator for realizing positioning is as follows: the LoRa locating communicator carries out data communication with the pre-authorized LoRa gateways in an indoor scene, when any LoRa locating communicator sends a data packet, the data packet is received by all LoRa gateways in the network range where the LoRa locating communicator is located, and each message is reported to the server. All LoRa gateways receive signals at all data rates on all channels at all times. This means that there is no overhead on the LoRa location communicators because they do not need to scan and connect to a specific LoRa network gateway, all LoRa gateways will send the same received packet to the server, capturing the arrival time with high accuracy using dedicated hardware and software built into the last generation LoRa gateway. The algorithm of the server side compares the arrival time, the signal strength, the signal to noise ratio and other parameters to calculate the most possible position of the LoRa positioning communicator, and then positioning of the LoRa positioning communicator is achieved.
In one or more embodiments of the present application, the acceleration sensor is a sensor capable of measuring acceleration. The damper is generally composed of a mass block, a damper, an elastic element, a sensitive element, an adjusting circuit and the like. In the acceleration process, the sensor obtains an acceleration value by measuring the inertial force borne by the mass block and utilizing Newton's second law. Common acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric, etc. depending on the sensor sensing element. That is, when an old person wearing the indoor fall detection wrist guard falls indoors, whether the old person wearing the indoor fall detection wrist guard falls can be determined by the acceleration data collected by the acceleration sensor during the period.
In one or more embodiments of the present application, the air pressure sensor is a thin film sensitive to the intensity of air pressure and a thimble control, and is electrically connected with a flexible resistor. When the pressure of the gas to be detected is reduced or increased, the film is deformed to drive the thimble, and the resistance value of the resistor is changed. The resistance value of the resistor changes. The signal voltage of 0-5V is obtained from the sensing element, is received by the data collector through A/D conversion, and then the data collector transmits the result to the processor in a proper form. That is to say, when the old person wearing the indoor fall detection wrist guard falls indoors, the air pressure sensor can collect air pressure data according to the air pressure change of the air in the corresponding extruded detected space, so as to judge whether the old person wearing the indoor fall detection wrist guard falls according to the changed air pressure data.
