Embodiment
Do into a line description below in conjunction with accompanying drawing to one embodiment of the present of invention:
As depicted in figs. 1 and 2; the mining wireless sensor node of band buffering protection function of the present invention, is located at the buffer pocket 3 of spherical shell 1 bottom primarily of spherical shell 1, the wireless senser 6 be located in spherical shell 1, symmetry and the buffer bar 2 be hinged on buffer pocket 3 is formed.Buffer pocket 3 is four, is arranged symmetrically with, and the buffer bar 2 linked with buffer pocket 3 phase tilts to be fixed on base or ground, and the buffer bar 2 that described inclination is fixed becomes 60 degree with the angle of horizontal plane, forms dual crossing plane double leval jib buffer gear.
As shown in Figure 3, described spherical shell 1 is fastened by upper spherical cap 5 and lower spherical cap 7 and is welded, spherical shell 1 internal symmetry is provided with four pieces of arch sheets 4 abutted against together, the middle part of arch sheet 4 is provided with the square plate 9 of fixed wireless transducer 6, and the end face of square plate 9 is provided with the pole 8 be connected with arch sheet 4.
As shown in Figure 4, described buffer pocket 3 comprises box body, is provided with steel ball 12 in box body, and the bilateral symmetry of steel ball 12 is provided with two springs 11 be separately fixed in box body.
As shown in Figure 5, wireless senser 6 is made up of MCU microcontroller chip, UWB radio transmitting and receiving chip, FLASH extended menory, signal conditioning circuit, usb circuit, PCB antenna, clock chip and power module; The output of MCU microcontroller chip is connected with usb circuit with UWB radio transmitting and receiving chip, FLASH extended menory, the output of UWB radio transmitting and receiving chip is connected with PCB antenna, clock chip is connected with MCU microcontroller chip, and power module is connected with clock chip with MCU microcontroller chip, UWB radio transmitting and receiving chip, signal conditioning circuit.MCU microcontroller chip selects MSP430F1611 low-power chip.Clock chip selects X1226.UWB radio transmitting and receiving chip model is XS110, and the wireless signal transmission frequency of this chip is 3.1GHz, and traffic rate is 110M/S.Power module is made up of, for MCU microcontroller chip, clock chip and UWB antenna transceiving chip provide voltage of voltage regulation two joint AA batteries and TC55RP33 power management chip.FLASH extended menory model is M25P80, and capacity is 1M, for the Memory Extension of MCU microcontroller chip.Usb circuit is made up of to I/O buffer chip NC7WZ126 and corresponding peripheral circuit protocol conversion chip FT232BM.
Operation principle: when this node runs into extraneous level or vertical impact forces, this impact energy is delivered to the spring in four buffer pockets of dual crossing plane double leval jib by spherical shell, and the spring apparatus with shock absorbing in buffer pocket, weakens spherical shell inside
The vibration of wireless senser.When impact energy is excessive, such as when mine caves in, weight slump causes double leval jib to destroy, at this moment can by the inner four pieces of arch sheet apparatus with shock absorbings of spherical shell, weaken the impact of impulsive force on wireless senser, ensure that node can carry out reliable real-time dynamic monitoring, and then provide the rescue information of effect to personnel after mine disaster.
