Wireless smoke detector based on ZYNQ7020

Abstract

The invention discloses a ZYNQ7020-based wireless smoke detector, which comprises a system architecture and hardware, and is characterized in that the system architecture comprises a single-point equipment terminal, an NB-IOT base station, an Internet of Things platform, a mobile phone terminal APP and a third-party server, the hardware comprises a power supply module, a sleep standby module, a CPU master control module, a field multi-sensor information detection module, a Zigbee wireless communication module, a binocular camera monitoring module and a remote holder control module, the sleep standby module is used for continuously monitoring a site when a fire disaster does not occur and starting a CPU control end and other modules, the Zigbee wireless communication module is used for wirelessly transmitting settlement data, and the binocular camera monitoring module is used for collecting on-site images and videos. According to the invention, the problems that a traditional smoke detector is inaccurate in monitoring parameter, complex in wiring, high in requirement for network bandwidth and the like are solved, data support and real basis are provided for predictability, timeliness and accuracy of fire scene judgment, and life and property safety of rescue workers and rescued persons is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of intelligent fire protection, and specifically relates to a wireless smoke detector, in particular to a ZYNQ7020-based wireless smoke detector. Background technique [0002] With the continuous improvement of people's living standards and rapid economic development in our country, various modern household appliances are increasing, and fire accidents that threaten our lives are also increasing. Therefore, safety problems in residential buildings, office buildings and other places are becoming more and more serious. The more it arouses people's attention, people are equipped with monitoring and alarm devices in order to be able to find out in advance to avoid significant loss of life and property. Among them, the smoke detector is one of the most important monitoring and alarm devices. [0003] Smoke detector is an important fire-fighting equipment. It realizes the function of fire warning through smoke co...

AI Technical Summary

Problems solved by technology

[0004] (1) The bus-type working method of traditional smoke detectors increases construction costs and complexity, and is not suitable for places where power supply is difficult, open and remote, and wiring space is difficult to plan.

[0005] (2) Traditional smoke detectors have a single working principle, high false alarm rate, slow response speed, and cannot perform remote alarms, requiring 24-hour personnel on duty

[0006] (3) The self-inspection ability of traditional smoke detectors is weak, and manual inspections are required for equipment failures, which increases labor costs and also creates hidden dangers of missed fire reports

[0007] (4) At present, wireless smoke detectors have achieved zero wiring, but the principle of smoke detection is still single, and the contradiction between sensor sensitivity and false alarm rate and false alarm rate still exists

[0008] (5) When using wireless smoke detectors, the video recording function is added to ensure the accuracy of the alarm, but the requirements for network bandwidth are relatively high. In addition, the transmission of on-site information in the background still requires manual visual judgment

[0009] (6) The smoke detector with video recording function consumes a lot of power, and it cannot work normally in some open places, such as forests, large-scale factories, warehouses, etc.

[0010] (7) The traditional smoke detectors are all in an independent and discrete state. When the detector fails, the host cannot be notified at the first time, and there is no linkage function between the detectors, which may cause "misjudgment" of the real situation on the scene
