Handheld Internet-of-Things signal analyzer with equipment debugging function

Abstract

The invention discloses a handheld Internet-of-Things signal analyzer with an equipment debugging function, and mainly solves the problems that a signal analyzer in the prior art can only test a single operator and does not have a function of directly communicating with Internet-of-Things equipment. The signal analyzer comprises a main control MCU for detecting an NB-IOT signal, and a PCB carriercalculation antenna circuit, an infrared transmitting and receiving amplification circuit, an LCD screen display circuit, a Bluetooth communication module, a key control circuit and three SIM card communication circuits which are all connected with the main control MCU, and the SIM card communication circuit comprises an intelligent SIM logic switch, an SIM card seat and an SIM card chip which areconnected with the main control MCU. Through the design, the signal intensity of three operators of mobile, Unicom and telecom can be inquired at the same time, so that the analyzer can be directly communicated with equipment such as an intelligent water meter and the like. Signal intensity of three operators of mobile, Unicom and telecom can be inquired without changing a machine and a card, andconfiguration and modification of parameters of the Internet-of-Things equipment are realized.

Description

technical field [0001] The invention relates to an Internet of Things signal analyzer, in particular to a hand-held Internet of Things signal analyzer with a device debugging function. Background technique [0002] Today, as the Internet of Things technology is becoming more and more mature, a large number of Internet of Things products have emerged from the market. Smart devices such as IoT electricity meters and water meters have entered people's field of vision and are closely related to the lives of ordinary people. If these devices want to remotely report and receive data through the network, they cannot do without NB-IOT signals. Usually, construction personnel are installing the equipment. When the NB-IOT signal strength is detected at the current location to determine whether it meets the installation requirements, the existing NB-IOT signal analyzers on the market have a single function: they can only detect the signal of one operator; poor portability: volume It i...
