Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment discloses a position of sitting reminiscences of exempting from to wear, its structure is shown in fig. 1 to fig. 4, mainly includes the casing, and whole casing small in size, the casing outside are equipped with charactron display screen and switch, and an ultrasonic ranging module is respectively laid at the positive upper and lower both ends of casing, and the back of casing is equipped with fixture, and this fixture mainly used is with the position of sitting reminiscences centre gripping on the back of the chair. The casing is inside to be equipped with central control module, power module and miniature shock dynamo, and power module gives the power supply of ultrasonic ranging module, and power module gives central control module power supply after stepping down through the step-down circuit, and two ultrasonic ranging modules, charactron and miniature shock dynamo all are connected with central control module electricity.
The power module in this embodiment adopts the 5V lithium cell as the input, and this 5V power directly supplies power for two ultrasonic ranging modules. The voltage of 5V is reduced to 3.3V by the ASM1117 voltage stabilizer, and then the central control module is supplied with power. R1 in the ASM1117 circuit of FIG. 4 is a current limiting resistor of the LED D1, which is used to make D1 work under normal condition when it is powered; c1 and C2 are output filter capacitors and are used for reducing output voltage Wen waves and inhibiting self-oscillation of ASM1117, C2 is a high-frequency filter capacitor, and C1 is a low-frequency filter capacitor.
The central control module of this embodiment adopts the STM32F103C8T6 chip, and two ultrasonic ranging modules adopt the HC-SRO4 module, and this module has 5 pins, and pin VCC connects the power module positive pole, and pin GND connects the power module negative pole, and pin Trig is trigger signal input pin, and pin Echo is the data output pin. The whole module adopts IO mouth to trigger the range finding, STM32F103C8T6 inputs a high level signal more than 10 microseconds for trigger signal input end (Trig), and the supersound transmitting port receives the automatic 8 40Hz square waves of sending of signal, starts the timer simultaneously, waits that the module receives the echo then stops timing and output the reverberation signal, and the reverberation signal pulse width is directly proportional with the distance of surveying, can calculate the distance according to the time interval, promptly: distance (high level time sound velocity)/2.
