Description
Technical Field
The invention relates to the technical field of low-voltage power grid communication, in particular to a device and a method for testing the quality of a wireless channel of a low-voltage power grid.
Background
With the continuous improvement of the distribution network and metering automation level of power grids and enterprises, a public network wireless communication channel becomes the most main transmission channel of low-voltage power grid monitoring data. Because the noise of a wireless communication channel is more and is greatly influenced by the actual geographic position, the on-line test of a wireless signal is an important work for troubleshooting the instability of a network before the position selection of a monitoring point and in the operation process.
At present, a perfect wireless network operation and maintenance system is not established in power enterprises, and a common wireless network signal test has three technical schemes, wherein the first scheme is to use a mobile phone as a simple test tool and judge the network condition through a signal intensity index on the mobile phone; the second scheme is that signal intensity information is sent to a master station at regular time through a wireless communication module, and the master station judges the network condition; the third scheme is that the timing and non-timing calling and testing are carried out through the service channel of the main station end, and the wireless network condition is judged according to the calling and testing result. The first and second schemes have obvious disadvantages that the monitoring index is too single, only one signal intensity is provided, only the power intensity of the signal between the wireless base station and the monitoring point can be explained, but the channel condition between the wireless base station and the master station is not monitored, and the actual condition of the current wireless network cannot be represented comprehensively and accurately; every three schemes are used for reversely deducing the quality condition of the wireless network according to the condition of a service channel from the perspective of service application, however, due to the interruption of the service channel, besides the wireless network fault, various reasons such as monitoring equipment fault, main station front channel blockage, wireless transmission module fault and the like exist, and therefore evaluation cannot be carried out through a one-sided test result.
In the prior art, the invention of China with the publication number of CN105451261A specially facilitates 2016, 3 and 30, and discloses a VoLTE wireless network testing method based on a mobile intelligent terminal. The method comprises the following steps: step (1): acquiring wireless network data through a data acquisition module of a wireless protocol stack of the mobile intelligent terminal; the data comprises layer 3 signaling, SIP signaling, wireless network parameters and cell parameters; step (2): and generating a LOG file by the data, importing the LOG to a post-analysis platform, analyzing KPI indexes of 7 elements according to the data, and generating a report file. The method realizes accurate acquisition of the Volte signaling of the wireless network and the parameters of the wireless network through the mobile intelligent terminal, can timely and effectively complete the integrity acquisition of the wireless network data, but does not relate to the test of the low-voltage power grid wireless network, and does not solve the problems existing in the low-voltage power grid wireless network test.
