Embodiment

Provide specific embodiment below in conjunction with accompanying drawing, further specify voice robot vehicle of the present utility model and how to realize.

Below by specific embodiment the utility model patent is described in further detail, following utility model patent is descriptive, is not determinate, can not limit the protection domain of the utility model patent with this.

A kind of voice robot vehicle, by direct supply 5V and direct supply DC24V, motor drive module (5) and Ling Yang single chip control module SPCE061A (1), detection module (2), speech processing module, LED display module (6), form the design control of voice robot vehicle, process experimental results show that it has higher security and steadiness, and realizes easily.

Show through above-mentioned finite element analogy contact analysis result, because the special design of this circuit, thereby can go to control the working direction and the speed of voice robot vehicle according to different voice.

As shown in Figure 1, it is system construction drawing of the present utility model, described single chip control module adopts Ling Yang SPAC061A system, described sensor module (2) provides process information, direct supply 5V (3) to be provided power supply to single chip control module (1) for single chip control module (1), speech processing module is controlled the motion conditions of voice robot vehicle then for gathering voice messaging by Single Chip Microcomputer (SCM) program, finally remove to control motor drive module and its information is shown by LED display module (6).Described direct supply 24V is a motor power of supplying with the voice robot vehicle.

As shown in Figure 2, be the running route figure of voice robot vehicle, adopt the starting of voice control dolly, when being the dolly name, it can be done accordingly and reply, and is ready simultaneously, when issue " advancing " order, dolly arrives the B point just from starting line A point along the black guide line.Dolly enters " bend district " after arriving the B point, arrives the C point along the circular arc guide line.In " bend district " driving process, adopt the software speed governing to guarantee that dolly passes through quickly and accurately.In the process of travelling, the time of travelling for the unit record dolly with the second.After dolly stops, playing automatically one section musical signification dolly travelled full journey, arrive safe and sound.When issue " reversing " order, dolly will prolong track slowly refunds, and when reversing finishes, also can play one section musical signification automatically and finish.

As shown in Figure 3, described single chip control module adopts Ling Yang SPAC061A system, and crystal oscillator and resonant capacitance on OSC320, OSC321 termination are getting final product work behind corresponding electric capacity and the resistance on the VCOIN termination then.The coupling capacitance of 0.1uF is to improve antijamming capability on other no vdd terminals and GND termination.
