Embodiment
Clearer for making the utility model implement object, technical scheme and advantage, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment is as follows:
1. collectivity Scheme Design
General system proposal (functional block diagram as shown in Figure 1) testing mobile phone adopts SAGEM OT76M type.Transmitting terminal sends data with single-chip microcomputer intercepting testing mobile phone, is packaged into basket tooth Frame and transmits and store in CF card by the wireless connections of basket tooth.Transmitting terminal is 89C2051, storage end 89C52 for single-chip microcomputer.Bluetooth chip adopts the ROK101007 of Ericsson, defers to bluetooth 1.1 standards, and authenticates by FCC/ETST type.Radio frequency is output as class2 level, supports USB, DART, and the interfaces such as PCM voice, I2C, support point-to-point and point-to-multipoint.Module is containing the radio-frequency module of baseband controller, flash memory and global general-use 2.4～2.5GHz ISM band, internal structure principle (functional block diagram as shown in Figure 2).
Testing mobile phone data sending terminal sends instruction to mobile phone, and by wireless sending module, sends the data of mobile phone output to storage device.Sending instruction is completed by 89C2051 machine.Wireless transmission completes by bluetooth module.Because 89C2051 only has a serial ports, so its P1.2 mouth is made to simulative serial port transmitting terminal (STXD).During normal operation, for sending instructions to mobile phone and receiving mobile phone feedback data, the data of mobile phone are added to blue-teeth data frame head so that bluetooth module identification simultaneously.Before normal operation, single-chip microcomputer also needs bluetooth module initialization, and now microcontroller serial port need receive the information that bluetooth module returns, and after initialization, microcontroller serial port need be switched to and mobile communication.So also need a channel switching signal S1 (being served as by single-chip microcomputer P1.3 mouth) (functional block diagram as shown in Figure 3,4)
This programme mobile phone, single-chip microcomputer, wireless transmission end common source line and ground wire, power supply is provided by battery of mobile phone, to reduce volume.
Storage device termination is received the data that send and is write CF card.Data with bluetooth frame head are removed frame head in PC.
2. the control of single-chip microcomputer to bluetooth module
Bluetooth specification has defined Host Controler Interface (HCI), for Bluetooth baseband controller and Link Manager provide command interface, realizes the access to hardware state Register and control register.Master controller transport layer provides the HCI transparent switch system of information, makes main frame can send HCI order, ACL or SCO data to basket tooth module.Main frame also can be received event, ACL or the SCO data that basket tooth module sends.HCI agreement has been stipulated four kinds of packet formats of HCI order, event and data: instruction grouping, event packets, ACL packet and SCO packet.Indication difference packet type for HCI packet frames, this indication should be sent before HCI grouping, as following table.
| HCI packet type | HCI divides into groups to indicate |
| HCI instruction grouping | 0x01 |
| HCI ACL packet | 0x02 |
| HCI SCO packet | 0x03 |
| HCI event packets | 0x04 |
HCI transport layer has USB, UART, PCM to transmit sublayer.This programme sends HCI by HCI UART layer and divides into groups.And RS232 is set is stop bit in 8 bit data positions, 1, no parity position, use Little-Endian form.Because HCI has HCI instruction, HCI event and HCI data-flow-control making mechanism, and single-chip microcomputer is directly connected with the short distance of basket tooth module, therefore without RST/CTS current control.
ROK 100 007 module bluetooth chipset comprise wireless receiving and dispatching layer, baseband layer, link manager layer and master control preparative layer.Because main frame is completely separated on hardware with master control preparative layer, need to connect bluetooth module and bluetooth host by HCI, for application provides support.Single-chip microcomputer, by bluetooth module initialization, sends data to mobile phone and adds the processing of bluetooth frame head, controls and sends to bluetooth module, and monitor the event that bluetooth module returns by HCI layer with HCI instruction.Single Chip Microcomputer (SCM) program adopts C Programming with Pascal Language, program circuit (functional block diagram as shown in Figure 5).
Bluetooth module initialization, first initialization is from equipment, and the main equipment that reinitializes, comprises that bluetooth module resets, reads bluetooth module address, state parameter is set and is initialized as principal and subordinate's module.If be initialized as from module, need to wait for that primary module connects.If be initialized as primary module, send order bag and go to connect from module.Successful connection, just can send data.If it is unsuccessful to return to event indication connection, primary module reconnects, until success.Can a successful connection in general 10m communication context.Transceiving data is complete, disconnects, concurrent reset command bag.Information format is with 16 transmission, and while sending packet, once maximum can send 127 characters.At receiving terminal, data are divided into parcel and receive, and receive form similar with data format, one by one.If it is synchronous that main frame or master controller lose in UART communication, need to reset, master controller is told main frame by transmission hardware fault event, main frame will send HCI_RESET instruction with reset master controller.
3. data transfer procedure
After linking bluetooth success, test data sends from mobile phone with 9600bps, then adds bluetooth frame head by single-chip microcomputer, with 57600bps, by simulative serial port, sends to bluetooth module to launch.Storage end bluetooth module is received data, sends storage end single-chip microcomputer to deposit CF card in 57600bps.The network operating state data of CF card storage, is finally sent to PC through storage device serial ports or USB interface.PC analysis software finally completes the CQT test of mobile communications network.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the illustrated technical scheme of aforementioned each embodiment, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the illustrated technical scheme of each embodiment of the utility model.
