Problems solved by technology

Due to performance defects of the traditional FSK / GFSK / OOK modulation technology, there are blind spots in the signal within a relatively narrow range (1 km open, less than 50 meters of diffraction), and a large number of transfer devices are required to complete a simple Communication links and related signal detection equipment can’t realize signal monitoring. The signal detection equipment in the laboratory is bulky, and field detection is not applicable at all. The detected equipment is usually equipment, not actual equipment, and the detected signal lacks authenticity.

Abstract

The invention discloses a portable spread spectrum signal sensing system. The portable spread spectrum signal sensing system comprises an intelligent terminal, a portable spread spectrum signal detecting device and a device to be detected; wherein the intelligent terminal is used for generating and issuing a sensing instruction, and for receiving and displaying the detection results returned by the portable spread spectrum signal detecting device; the portable spread spectrum signal detecting device is used for receiving the sensing instruction issued by the intelligent terminal, generating a detection instruction according to the sensing instruction, and issuing the detection instruction; and for receiving the reply data issued by the device to be detected, calculating the signal quality according to the signal quality, and sending the signal quality to the intelligent terminal as the detection results; and the device to be detected is used for receiving the detection instruction and sending the reply data including the signal strength value received by the device to be detected to the portable spread spectrum signal detecting device after receiving the detection instruction. The equipment adopted by the invention is easy to carry, therefore, the transportation cost is saved and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of signal detection, in particular to a portable spread spectrum signal detection system and method. Background technique [0002] Compared with traditional modulation technologies such as FSK / GFSK / OOK, the current spread spectrum modulation technology (LoRa) has greatly improved the reliability and distance of communication. The premise of traditional FSK / GFSK / OOK modulation technology demodulation is that the effective signal strength must be greater than the noise signal strength, while the spread spectrum (LoRa) modulation technology can demodulate the effective signal submerged in the noise. Due to performance defects of the traditional FSK / GFSK / OOK modulation technology, there are blind spots in the signal within a relatively narrow range (1 km open, less than 50 meters of diffraction), and a large number of transfer devices are required to complete a simple Communication links and related signal dete...
