Embodiment Construction

[0022] Reference figure 1 , The implementation steps of the present invention are as follows:

[0023] Step 1. Based on the libevent framework, build a multi-concurrent server that supports 1 main thread and 4 worker threads

[0024] The libevent framework refers to an event-triggered network library, which internally uses select, epoll, kqueue, and IOCP system calls to manage the event mechanism.

[0025] Using the libevent framework used inside the server, 4 worker threads are set up in a thread pool to form multiple concurrent servers, which can serve multiple clients at the same time, such as figure 2 Shown. Different clients can send different commands to the receiver at the same time without blocking. Multiple concurrent servers will parse the commands through different threads and then send them to the receiver.

[0026] Step 2. Build a monitoring system

[0027] Connect 6 antennas, 6 receivers and clients in sequence to form a monitoring system, and connect the system to multi...

Abstract

The invention discloses a multiple concurrent wireless frequency spectrum monitoring method, mainly solving the problem that a receiver in a current frequency spectrum monitoring system only supports unidirectional connection with a client, but does not support multiple clients to simultaneously send commands to the receiver; and a current frequency spectrum analysis method is more and more difficult to truly reflect a complex frequency spectrum situation. The method comprises the steps of: (1) building a multiple concurrent server supporting one main thread and four work threads based on a libevent framework; (2) constructing a monitoring system; (3) configuring task parameters; (4) the receiver collecting data; (5) the multiple concurrent server employing the Multiquadric method in an interpolation method to stimulate the frequency spectrum data transmitted by the receiver; and (6) drafting a frequency spectrum situation graph through color mapping. According to the scheme, the method achieves the purposes of simple operation, convenient enforcement, safety and reliability, and has high use value and popularization value.

Description

Technical field [0001] The invention relates to the field of radio communication, and in particular to a spectrum monitoring method, which can be used for monitoring a strong electromagnetic environment at a limited point. Background technique [0002] Wireless spectrum is a limited, reusable natural resource, and it is also a valuable strategic resource. With the development of wireless communication technology and the continuous growth of people's demand for radio communication services, the electromagnetic environment has become increasingly complex, and the management of spectrum resources has become more and more important. [0003] A common networked small-scale spectrum monitoring system includes a receiver and a client. After the receiver receives the command sent by the client, it sequentially performs command analysis, command execution, and data collection. The client can only wait for the receiver to return the collected data. In this spectrum monitoring system, the re...
