Technical field
The present invention relates to wearable technology field, be specifically related to the application of MIPI camera lens in wearable camera-shooting and recording device, for wearable device increases shooting-recording function.
Background technology
At present, carry out in the sensor-host attachment facility of data acquisition at modal nine axle sensors that utilize, nine axle sensors, the microprocessor integrated the data of nine axle sensor collections and the wireless device transmitting the data integrated all integrate, and wherein radio data-transmission equipment is generally integrated WIFI module on circuit boards.But the existing circuit board ubiquity being integrated with the large module of nine axle sensors, microprocessor and Wireless Data Transmission three the larger problem of physical dimension, is difficult to be applied on the less exact instrument of size, especially carry-on electronic equipment.In addition, carry out data by WIFI module and transmit the support that namely inevitable common fault need third party's Virtual network operator, the dependability of product is declined.In addition, WIFI belongs to WLAN WLAN (wireless local area network), is the networking pattern that a kind of multiple terminal is transmitted simultaneously, and the magnetic interference of how to resist ambient electronics is a difficult problem equally.To this, existing sensor-main process equipment is effective solution not, only have some simple structure optimization measure and technology upgrading, fundamentally do not solve the contradiction that sensor-main process equipment itself exists, improve use cost to a certain extent on the contrary.
Dress to overcome excessive being not easy to of the physical dimension existed in existing sensor-host attachment facility, ubiquitous, the deficiency that poor anti jamming capability not easily realize Lossless transport high to third party's wireless network environment dependence of WIFI link block, the invention provides one
novelsensor-host attachment facility, the miniaturization of separate modular that what this connection device not only can break the whole up into parts realize, be convenient to carry-on use, and by replacing traditional WIFI link block, drastically increase operating performance and the reliability of data transmission module, and the quality transmitting data obtains effective guarantee.
Summary of the invention
Nine axle sensor modules and microprocessor, data transmission module are individually fixed in two pieces of circuit boards by the present invention, are connected between circuit board by FPC winding displacement, realize the transmission of data, realize the volume-diminished of sensor assembly on this basis to 0.8cm*0.8cm.In addition, the use bluetooth module of the invention, as wireless transmission hinge, perfectly solves the problems referred to above that traditional WIFI data transmission module exists.
The new design that nine axle sensors are combined with microprocessor and bluetooth module, mainly comprises four major parts: nine axle sensor modules, microprocessor module, bluetooth module and connect FPC winding displacement, the computing machine of above-mentioned module.
The present invention solves the problems of the technologies described above by the following technical programs: traditional sensor-main process equipment is by integrated to sensor, microprocessor and wireless transport module and be fixed on one piece of circuit board, and this design fundamentally determines the larger-size contradiction of sensor-main process equipment.In the present invention, microprocessor module and bluetooth module are integrated on same circuit board, jointly perform the work such as data acquisition, pre-service and transmission, nine axle sensor modules are integrated separately.Nine axle sensor modules are connected by FPC winding displacement with corresponding microprocessor module, and can realize that the data that nine axle sensors are collected are transferred to microprocessor module and process accordingly, FPC winding displacement used has good pliability and bending property.
On the other hand, the Bluetooth communication modules of the use of the present invention's innovation instead of traditional WIFI link block, and Bluetooth communication modules can realize the exchanges data between microprocessor and main frame.Bluetooth is a kind of technical manual of short-distance wireless communication.Because bluetooth has ISM (industrial, the scientificandmedi-cal) frequency range being operated in 2.4GHz, it is the connected mode exclusively enjoying fixed-bandwidth one to one that bluetooth connects, and be not subject to the interference of other equipment, reliability is stronger.In addition, the non-destructive of transmitted data effectively can be ensured by Bluetooth transmission.
The invention has the beneficial effects as follows, can realize the miniaturization of single module volume, by by integrated separately for nine axle sensor modules, the volume of module can control within 0.8cm*0.8cm, improves the usability carried with.
Connect two modules by FPC winding displacement, the requirement that can meet ergonomics simultaneously He carry with, the design of this fractionation also reduces design cost simultaneously.
Traditional WIFI link block is replaced by using bluetooth module, enhance the adaptability of wireless data transfer module, can use under any indoor and outdoor surroundings and light environment, the impact of wireless device around effective opposing, thermal adaptability is extremely strong, and classification of waterproof can reach IP63.Bluetooth module is by ISM2.4GHz radio band transmission data, and hypervelocity computation rate reaches 480fps, and can realize the Lossless transport of data.
