Wireless sensitivity test method and device based on radio frequency technology

Abstract

The invention discloses a wireless sensitivity test method based on radio frequency technology, which comprises the following steps of: setting an initial value of radio frequency power of a radio frequency signal source, and analyzing a message sent by the radio frequency signal source; if the bit error rate of the message is less than or equal to a preset threshold value, reducing the radio frequency transmitting power at 1dbm / time; when the bit error rate of the message is greater than the preset threshold value, increasing the current radio frequency transmitting power by 1dbm to serve as wireless sensitivity; if the bit error rate of the message is greater than the preset threshold value, increasing the radio frequency transmitting power at 1dbm / time; and when the bit error rate of the message is less than or equal to the preset threshold value, taking the current radio frequency transmitting power as the wireless sensitivity. The problem that the wireless sensitivity of a radio frequency signal is not accurately tested in the prior art is solved.

Description

technical field [0001] The present application relates to the field of low-voltage communication, in particular to a wireless sensitivity testing method based on radio frequency technology, and to a wireless sensitivity testing device based on radio frequency technology. Background technique [0002] Under the background that power grid companies are vigorously promoting electric energy data collection, carrier wave and wireless communication methods rely on price advantages and can realize functions such as power outage reporting, and are gradually favored by the market, and are more and more widely used in centralized copying systems. Due to the complexity of the external environment, it will affect the radio frequency performance, and then affect the equipment communication. The module with low wireless sensitivity will have the problem of poor communication effect, and the size and position of the patch components are fixed when the stencil is made. If the device is chang...

Problems solved by technology

[0003] At present, there is no easy way to test the wireless sensitivity. The existing test method is to hold the module in an open space and keep it away from the receiving device, and judge the wireless sensitivity according to the distance. There are many uncertain factors and then Affect the accuracy of data, resulting in inaccurate value of wireless sensitivity
