Technical field

The utility model is a kind of scatter channel test data memory module in the communications field, is specially adapted to the unmanned no computing machine long-term test on duty of scatter channel, and is easy to use.

Background technology

At present the scatter channel integral test system measures that project is many, function is strong, automaticity is high and ability real-time analysis test data and provide the result; But being this scatter channel integral test system, its shortcoming need one to overlap independently system; Need the cooperation of computing machine, cost is high, uses inconvenience.So, develop online detection of a kind of small-sized scatter channel test data and automatic memory module just highly significant.This testing apparatus is portable, and on-line testing does not influence other business.

The utility model content

The purpose of the utility model is to provide a kind of automaticity height, small volume and less weight, easy to use, the real-time online scatter channel test data collection and the memory module that do not influence proper communication.

The purpose of the utility model is achieved in that

A kind of scatter channel test data memory module; Comprise scatter channel test data collection module 1, processing and memory module 2, demonstration and control module 3, time module 4 and power module 5; It is characterized in that: the 1st input port of described scatter channel test data collection module 1 carries out after filtering, amplification, detection, the A/D conversion the 2nd output port through scatter channel test data collection module 1 with the signal of outside input and exports to and handle and the 1st input port of memory module 2; Processing and memory module 2 are controlled data storage on storage facilities through processors, file management; Handle and memory module 2 exports the data message of handling, temporal information to and shows and the 1st input port of control module 3 through the 2nd output port, show and the control information of control module 3 exports to through the 2nd output port and handles and the 3rd input port of memory module 2; The temporal information of time module 4 exports the 4th input port of processing and memory module 2 to through the 1st output port.

Wherein, described scatter channel test data collection module 1 comprises filtration module 6, amplification module 7, detection module 8 and A/D conversion module 9; Wherein the outside signal of the 1st input port of filtration module 6 connection is gone into; Export the 1st input port of amplification module 7 after the filtering to through the 2nd output port; Signal after the amplification exports the 1st input port of detection module 8 to through the 2nd output port; Be connected to the 1st input port of A/D conversion module 9 after the detection through the 2nd output port, export to through the 2nd output port after the A/D conversion and handle and the 1st input port of memory module 2.

Wherein, described processing and memory module 2 comprise processor 10, file management control module 11 and memory device 12; Wherein the 1st input port of processor 10 connects scatter channel test data collection module the 2nd output port; Processor 10 is handled the back exports file management control module 11 to through the 2nd output port the 1st input port; Export the 1st input port of memory device 12 to through the 2nd output port of file management control module 11, data are saved in memory device 12.

The utility model is compared with background technology has following advantage:

1. automaticity height, small volume and less weight, easy to use.

2. do not influence proper communication, real-time online detects.

3. can realize unmanned, automatically storage.

Embodiment

With reference to Fig. 1; The utility model scatter channel test data collection module; Handle and memory module; Demonstration and control module, time module, power module; Wherein the outside signal of the 1st input port of scatter channel test data collection module connection is gone into, and the 2nd output port of scatter channel test data collection module is connected to the 1st input port of processing and memory module, and the 2nd output port of processing and memory module is connected to the 1st input port of demonstration and control module; The 2nd output port of demonstration and control module is connected to the 3rd input port of processing and memory module, and the 1st output port of time module is connected to the 4th input port of processing and memory module.Power supply go out end+V ,+the V2 voltage end is connected with each modular circuit respective electrical source port respectively.

With reference to Fig. 2, the effect of this practical scatter channel test data collection module 1 is the signal of sending here to be carried out filtering, amplification, detection, A/D conversion give and handle and the processor of memory module is handled.

With reference to Fig. 3, this practicality is handled and the effect of memory module 2 is that the data of sending here are handled, and leaves in the memory device with document form through the file management control module.File memory format adopts the TXT form, sets up catalogue with current date, and the current time is set up filename, creates a file in per 2 minutes, and writes image data in the newly-established file, and is easy-to-look-up like this, conveniently checks.

The utility model power supply 5 provides parts WVs at different levels, implements to adopt general integrated regulated power supply to make, and output+V voltage is+1.2V voltage that output+V2 voltage is+3.3V voltage.

Storage time is relevant with memory rate according to memory capacity, is example with the SD card of a 8G capacity, and sampling rate is 200Hz; Figure place is 16bit; Then requiring writing speed is 3.2KB/s, and the card of a 8G capacity can be 8 000 000/3.2=28.9 days storage time, nearly one month; If the employing high capacity SD card time can be longer, really realized long-term unmanned.Scatter channel information is gathered in accumulation in test, and to understanding and grasping scattering properties, the development scatter communication plays an important role.
