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.

Simple multimeter can not measure True RMS of power frequency if there mixed harmonic components. In order to solve this problem, a method is adopted to design a measurement system by using STC Single Chip Microcomputer (SCM). It changes current into voltage by using I/V conversion circuit. Then analog signal turns into digital signal through AD converter. Finally, the Single Chip Microcomputer treats and calculates the data by the RMS algorithm. Sampling frequency of the system is set as 6400sps by Single Chip Microcomputer. This kind of designment uses software instead of hardware and reduces the costs. The realization of the system shows the validation and transportability of the algorithm. The testing data show that this system can measure True RMS of power frequency. The relative full scale error is smaller than 1.284%.
