Signal processing method and alarming device

Abstract

The invention provides a signal processing method and an alarming device. The signal processing method is applied to the alarming device, and the alarming device is used for monitoring safety situations of a security and protection region. The signal processing method includes the steps that first signals and second signals in the at least one security and protection region are received by a first interface and a second interface of the alarming device, wherein the first signals and the second signals are different in type; the first signals and the second signals are analyzed to obtain third signals and fourth signals for indicating whether the security and protection region is invaded or not; the third signals and the forth signals are fused based on the preset logic operation to obtain fusing signals, an alarm unit connected with the alarming device is controlled to give an alarm according to the fusing signals, and alarming by analyzing the multiple signals in different types is achieved. Compared with the existing mode of alarming by analyzing single signals, the information of the security and protection region can be collected in different modes through the multiple signals in the different types for confirming whether invasions exist or not, and the accuracy of multi-type signal invasion detection is higher than that of single-signal invasion detection.

Description

technical field [0001] The invention relates to the technical field of alarm equipment, in particular to a signal processing method and alarm equipment. Background technique [0002] With the deepening of people's awareness of safety, people's demand for alarm equipment has also increased. At present, various types of alarm equipment produced by major manufacturers include: infrared detection alarm equipment, microwave detection alarm equipment and intelligent video alarm equipment. [0003] The working principle of the above-mentioned various types of alarm equipment is: receive the signal sent by the sensor arranged in the security zone, analyze the signal to determine whether an alarm is required; if it is determined that an alarm is required, generate an alarm signal to control the alarm device Make an alarm. The security zone is a place to be monitored. [0004] For example, the above-mentioned infrared detection and alarm equipment can receive the infrared signal se...
