Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to a kind of multifunctional intellectual wheelchair control system, as shown in Figure 1, comprise interconnective single-chip microcomputer and motion control circuit, described single-chip microcomputer also respectively with for unexpected wireless communication line of reporting to the police, for show distress signals display circuit, for the electric power management circuit of managing electrical power with for controlling the key circuit of wheelchair, be connected.
Described single-chip microcomputer is STC125A60S2 chip, adopts wireless communication module to carry out SMS alarm service function and is partly comprised of radiating portion and receiving terminal, the mobile phone that receiving terminal had both used for domestic monitoring people.According to user's demand, set in advance one or more alarm mobile phone numbers, when running into accident, by alarm keys intelligent wheel chair alarm, will automatically send note and report to the police to tutorial mobile phone; Guardian receives after note, can obtain the further details that meet accident by answer short message, to help to judge whether the site disposal that need to arrive in the very nick of time; The display screen simultaneously of reporting to the police shows distress signals, the on-the-spot people's that sought to meet accident help.Whether the utility model can be full of whether normal operation is monitored in real time with solar electric power supply system to rechargeable battery.According to the information feedback control motor operation of wheelchair rocking bar sensor feedback, disabled person only need to just can realize the walking freely of intelligent wheel chair lightly by rocking bar like this, and it is convenient to control.
Described wireless communication line is GSM transmission circuit; Described single-chip microcomputer is connected with XL02-232AP1 transport module by UART interface, and described XL02-232AP1 transport module is connected with GSM transmission circuit.Described GSM transmission circuit is realized by the TC35i chip of Siemens.
As shown in Figure 2, XL02-232AP1 is UART interface half-duplex wireless transport module, can be operated in the public frequency range of 433MHz.Meet European ETSI(EN300-220-1 and EN301-439-3), meet wireless control requirement, without demand frequency occupancy permit.This module aims at for the wireless telecommunications between various serial equipments, as computer, and single-chip microcomputer, various machinery and equipment serial ports etc. can directly upgrade to wireless link, without extra programming in original wired connection, compatible for wired communication serial port protocol, easy to use flexible completely.
As shown in Figure 3, described display circuit consists of 12864 LCDs with character library.Band character library 12864 LCDs display resolutions are 128 * 64, are built-in with 8192 16 * 16 Chinese characters and 128 16 * 8 ascii character-sets, can form complete Chinese man-machine interaction graphical interfaces.
Described electric power management circuit comprises charge/discharge control circuit, voltage collection circuit, current collection circuit and temperature sampling circuit, and described charge/discharge control circuit, voltage collection circuit, current collection circuit and temperature sampling circuit are connected with single-chip microcomputer respectively.
As shown in Figure 4, described charge/discharge control circuit comprises triode and the TLP250 driving circuit of series connection successively, and the output terminal of described TLP250 driving circuit is used for controlling battery feed.In this circuit, select the Power MOSFETIRF3205 of IR company as the switching tube of control of discharge.When single-chip microcomputer provides high level, triode Q5 (S9013) conducting, TLP250 exports high level, the gate source voltage of IRF3205 by clamper in 10V.Now, MOSFET conducting, accumulator powers to the load, contrary, when control of discharge end provides low level, triode cut-off, the gate source voltage of IRF3205 is less than threshold voltage, MOSFET can not conducting, is equivalent to switch in off-state, and accumulator can not power to the load.
