Fire Detector

Along with the rapid development of computer, IC and signal disposal technology,fire alarm system has been more integrated,intelligent and multi-functional. The method of fire detection has also changed from single signal to multiple signal. Temperature sensorPhotoelectric smog sensor and CO sensor are integrated to a compound detector for fireproof. All kinds of signal will be judged by single-chip microcomputer. NN intelligent arithmetic is applied to software design. The Multi-signal synchronization detection is simulated by MATLAB.

<pre>There are several differences between the two types of alarm systems, conventional systems and addressable systems. It is important to carefully determine the introduction of a fire alarm system according to the installation environment. Talking about the main difference relates to how the connected device communicates with the main control panel by sending a signal. Cost is another factor that can be a determinant of your chosen fire alarm system. In this paper, we proposed smart addressable fire detection system. In the proposed system, <span>IoT</span> was used and the network was constructed using <span>ZigBee</span> module. In the configured network, it consists of a local server and a control server. The local server controls the addressing sensor and sends the information obtained from the sensor to the control server. The control server receives data transmitted from the local server and enables quick fire action. In the actual implementation, the local server used the Lycra controller and <span>ZigBee</span> module. In addition, the control server used the Raspberry Pi and <span>ZigBee</span> modules and connected to the Ethernet so that the administrator could monitor or control the local server.</pre>

Abstract With the rapid development of society and economy, various laboratories have become more complete in number and equipment, but subsequent laboratory accidents frequently occur. Therefore, it is imperative to construct a laboratory safety management system to ensure the safety of laboratory personnel and complete equipment. This article intends to design a smoke alarm, which mainly includes measuring the sensitivity of the smoke sensor to the concentration of smoke in the air, and the linear change of the sensor converting the corresponding analog signal into a digital signal. By designing the fan speed to be controlled by the change of smoke density, the speed of the motor is adjusted. And the alarm module can sound an alarm when the smoke concentration is certain, and at the same time, it can automatically cancel the alarm when the smoke concentration decreases. Finally, a simulation experiment is designed to simulate the effect of the sound alarm of the smoke alarm disperser on the dispersal of smoke under different working environments.

With the rapid development of computers and aggravation of competitiveness in employment, the course content system of Microcomputer Principle and Interface Technology with 8086/8088 CPU as the core is questioned by more and more people. Based on this, the course reform of Microcomputer Principle and Interface Technology was proposed. Recombining and optimizing the contents of "Microcomputer Principle" and "Single-chip Microcomputer”. Constructing the course system with Micro Controller Unit (MCU) and embedded as the main contents. The ways of teaching reform was discussed and task-driven method, learning by doing teaching method and Proteus simulation software were applied in teaching effectively. The practice proves that the teaching reform obtains a better teaching effect, arouses students' learning initiative and improves the students' project practice ability, comprehensive application ability and innovation consciousness.
