INTRODUCTION
With
the growing popularity of Internet technology, the processing ability of cloud
data becomes more powerful, and the interaction among various data is more
diverse. Therefore, the exploitation of the artificial intelligence instruments
based on the data interaction is blooming. As a typical field of intelligence
instruments, the intelligent vehicle system can be integrated into the speech
recognition technology to improve the intelligent level [1]. On the one hand,
it is convenient to convey various commands of the operator accurately, on the
other hand, the smart vehicle could implement the operator’s command
efficiently and orderly. In the next section, the structure analysis of the
intelligent vehicle for the distribution system is introduced, and the hardware
and software subsystems will be constructed to complete the specific
assignments in the section ċ
and Črespectively.

followed by the conclusion.
As a
consequence, the handled information will be transmitted to the SCM MSP430F169
through Bluetooth wireless communications. B.Single Chip Microcomputer As the
core component of the whole hardware system, the SCM MSP430F169 collects all
kinds of input information, refine rough data and control the external
equipment. Texas instruments (TI) had introduced the low power consumption
microprocessor MSP430 series at the end of the twentieth century. As one member
of them, the SCM MSP430F169 has the advantage of strong capacity of handling
data, fast operation speed, high on-chip resources integration, low power
consumption, stable operation and flexible peripheral interface [5]. The SCM
MSP430F169 consists of many function modules: the 16-bit central processor CPU;
16-bit timer/counter B7 with seven kinds of capture Comparator; the timer A;
Direct memory access (DMA) controller; 12-bit AD/DA converter; Multiplier; All
kinds of memory (flash memory, random access memory, etc..); 6 separate 8-bit
parallel ports; Crystals and clock circuit; watchdog circuit and so on.
According to this structure, encapsulation of MSP430F169 is 64 pin, which can
be connected with all kinds of external interface components to realize the
interaction of information [6]. Therefore, connecting the Bluetooth wireless
transmission module, the SCM MSP430F169 will receive the recognized digital
information by means of serial communication. C.Bluetooth Wireless Communication
Bluetooth is a kind of wireless transmission technology standards, data can be
transmitted among the fixed hardware devices, mobile devices and Local Area
Network (LAN) in the short distance by using Bluetooth technology. Moreover,
Bluetooth protocol supports RS-232 serial data transmission standards [7].
The
internal hardware structure of Bluetooth chip includes the Link Manager (LM),
Link Controller (LC) and the wireless transceiver. The working frequency of the
chip is 2.4G HZ to 2.48G HZ which is decided by the wireless transceiver. LM is
mainly responsible for real-time monitoring and safety control of Bluetooth
device link. LC follows the provisions of the agreement to complete the
packaging of data and the monitoring of service [8]. The data transmission
modes of Bluetooth technology are packet switching mode and circuit switching
mode. Therefore, using the Bluetooth technology, both digital data and voice
data can be transmitted. Here, we choose the module DX-BT05 4.0, which includes
the TI CC2541 chip, has 256K storage space, follows V4.0HL Bluetooth
specification, and supports the AT command. The device name, password, and baud
rate of serial communication can be set according to user requirements. The Pin
figure is presented in the figure 3.
As shown in the figure 3, the pins
of UART_RX and UART_TX denote the receiving and transmitting of data
respectively. The pins of SDA and SCL represent data port and clock port
respectively. The SCM can receive digital speech information by connecting with
the Bluetooth chip. The processed data can be applied to control the DC motor
driver to actuate the DC motor running.
