A) data generator is connected with wherein system equipment wireless network as standard device, inserts tested network;
B) data generator sends Frame to system equipment equably with maximum rate, and is counted the number of data frames Ns of transmission by data generator;
C) option is confirmed in the appointment of the Frame of transmission, and with data-analyzing machine monitor channel Frame, the statistics access device is confirmed the number of data frames Nr of reception, and calculating packet loss is (Ns-Nr)/Ns;
D) network connection of data generator disconnection and system equipment, after 5 minutes, repeating step is a) to c at interval) test 5 times;
E) average packet loss ratio of the each test of record, position, distance, frequency, signal strength signal intensity, data generator signal strength signal intensity;
F) respectively according to different frame lengths (comprising: 8,16,32,64,128 Byte) repeating step is a) to e);
G) respectively according to different transmission ranges (comprising: 50,75,100,125 m) repeating step is a) to f).
5, the real-time demonstration of test process: the application server of central platform is display network layout plan and topology diagram, energy and other parametric line figure, data transfer path etc. in real time, and is transferred to client computer and checks for the client.
6, test record: the test data that the data server storage test network of central platform sends, the test instruction of OAMAgent record.
One of ordinary skill in the art will appreciate that all or part of step in the whole bag of tricks of above-described embodiment is to instruct relevant hardware to finish by program, this program can be stored in the computer-readable recording medium, storage medium can comprise: read-only memory (ROM, Read Only Memory), random access memory (RAM, Random Access Memory), disk or CD etc.
More than high speed sensor network test macro that the embodiment of the invention is provided be described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
