Embodiment
The utility model is described in further detail in embodiment below in conjunction with accompanying drawing
As shown in Figure 1, need according to practical application, the Hardware Design of wireless measuring system is host computer one a slave computer structure, promptly is divided into collector and control end two parts.Collector require to select different sensors to come the acquisition monitoring parameter according to monitoring, realize to desired parameters real-time collection, processing, with the Bluetooth wireless communication of control end; Controller can adopt PC or bluetooth PDA etc., realizes the control to collector, and image data is received, extracts, handles, stores, analyzes and shows.Collector hardware mainly is made up of signals collecting and conversion module, processor module, bluetooth communication, power supply module and DLL (dynamic link library).Signals collecting and conversion module: comprise sensor and ADC, finish collection and A/D conversion to the multiple sensor simulating signal; Processor module: the core of collector, adopt the AVR single-chip microcomputer as controller, realize control to other modules, bluetooth communication is handled and be submitted to the multiple signals of gathering carry out wireless transmission; Bluetooth communication: communicate with the communication protocol of control end, mainly realize the wireless receiving and dispatching of control end to the controlled in wireless and the image data of collector according to system's agreement; Power supply module: be each module for power supply of system, guarantee that collector systems can long-time steady operation.
As shown in Figure 2, controller module is the core of collector systems, and the control module of collector is selected the ATmega128L microcontroller of Atmel company for use among the design, and it adopts 8 low-power consumption microcontrollers based on risc architecture of COMS explained hereafter.
Power supply: employing+3V powered battery, for the coupling bluetooth module+the 3V operating voltage, single-chip microcomputer adopts same supply voltage with it, thereby makes interface circuit simple, need not voltage transitions.Simultaneously, adopt low-voltage power supply also can satisfy the low-power consumption requirement of system.
Modes such as external crystal-controlled oscillation, outside RC oscillator, inner RC oscillator, external clock reference can be chosen in the work clock source of clock: ATmega128L.The selection in work clock source designs by the internal fuse position of ATmega128L, and modes such as fuse bit can be programmed by JTAG, ISP programming are provided with.This patent adopts external crystal-controlled oscillation, and frequency is 7.3728MHz, can satisfy the processing power requirement, can satisfy the low-power consumption requirement again.
Reset: adopt electrify restoration circuit, because system works is under unattended situation, so need not the hand-reset function.
Storage: have the program storage (Flash) of 128KB, the data-carrier store (SRAM) of 4KB and the EEPROM of 4KB in the sheet, can satisfy native system program and data storage requirement, need not to expand External memory equipment.
Interface: external interface comprises jtag interface, UART interface and sensor interface.Carry out the download and the debugging of program by jtag interface; Carry out exchanges data and control by UART interface and bluetooth module; Link to each other with sensor by the ADC input channel.
The design of antenna is most important in the performance history of blue tooth products, and the quality of its design often is related to the distance and the quality of transmission.Present modal Bluetooth antenna has dipole antenna, inverted F shaped antenna and small ceramic antenna etc.Because these antenna has approximate isotropic radiation pattern and advantage simple in structure, that cost of manufacture is low, so be fit to very much the use of embedded Bluetooth device.Adopt the Rufa 2.4GHz pottery Bluetooth antenna of gigaAnt company in this patent, packing forms is a Surface Mount.
As shown in Figure 3, in order to reach impedance matching and good filtering effect, balun TDK HHM-1517 and wave filter Soshin MDR 771F have been adopted in the junction of antenna and master chip.The bluetooth communication of collector systems is connected by standard UART mouth with the ATmega128L controller.
As shown in Figure 4, collector software flow.At first, behind system's electrifying startup, carry out system initialization; Then, whether the inquiry bluetooth module sets up correct connection, sets up the Bluetooth communication path; Wait for the acquisition that control end sends, adopt interrupt mode to start a data acquisition and process of transmitting; After sending end, whether inquiry has the termination acquisition, if having, then finishes master routine, otherwise continues to wait for acquisition; Whether in data acquisition or process of transmitting, it is sufficient to detect battery electric quantity, if the electric weight deficiency then finishes master routine.
