Intelligent formaldehyde alarm device

Abstract

The invention provides an intelligent formaldehyde alarm device; the intelligent formaldehyde alarm device not only can be used for intelligently splitting and splicing, thereby improving the detection efficiency, but also is provided with a walking mechanism capable of automatically walking under the control of a controller, the controller is used for carrying out comparison and judgement according to the received formaldehyde concentration information and judging the formaldehyde concentration relation between the split sub-alarm devices, the walking mechanism is used for controlling the whole formaldehyde alarm device body and the walking routes of all the sub-alarm devices under the indication of the controller, the formaldehyde alarm device is ensured to continuously move towards theposition with higher formaldehyde concentration, and therefore the formaldehyde leakage position is determined; accordingly, the intelligent formaldehyde alarm device in the invention can be used forchanging system setting, so that the walking mechanism is used for controlling the whole formaldehyde alarm device body and the walking routes of all the sub-alarm devices under the indication of thecontroller, and the formaldehyde alarm device is ensured to continuously move towards the position with lower formaldehyde concentration, so that an optimal evacuation route during the formaldehyde leakage is determined.

Description

technical field [0001] The invention belongs to the field of alarm device equipment, and in particular relates to an intelligent formaldehyde alarm device. Background technique [0002] Long-term exposure to low-concentration formaldehyde vapor may cause headaches, weakness and other symptoms. According to foreign reports, 14% to 16% of workers have digestive disorders, excitement, tremors, and visual disturbances after exposure to formaldehyde. In workshops where the concentration of formaldehyde reaches 0.2-0.7mg / m3, workers who work for a long time have symptoms such as loss of appetite, weight loss, fatigue, headache, palpitations and insomnia. According to reports, formaldehyde can also cause tactile, pain and temperature disturbances, excessive perspiration on one side of the body, and unequal skin temperature on both sides of the body. The proportions of eye and throat irritation and chest pressure in workers exposed to low concentrations of formaldehyde for a long ...

Problems solved by technology

[0003] The application with the application number CN201711204576.X discloses an alarm signal output device, detection and alarm equipment, and a detection and alarm platform system. The wireless external output device outputs an alarm signal by detecting the voltage or current change of the device to be tested. The alarm signal output device It can be placed in the battery position of the device, which is convenient for installation and small in size, but the alarm device can only perform formaldehyde alarm detection on a specific device, and cannot be applied to a complex environment of multiple devices. At the same time, because the alarm device is fixedly installed on one device For complex and large equipment, the specific location of formaldehyde leakage cannot be determined, which will cause troubles for subsequent maintenance work

[0004] The application document with the application number CN201721089358.1 discloses a high-efficiency purifiable air gas detector. A formaldehyde sensor is installed on the side wall of the air monitor, and an air purification device is also provided to purify the air. Although the gas detector It can be moved, but it cannot intelligently move according to the concentration change of the detected gas, and does not have the function of intelligent detection

[0005] Existing formaldehyde alarm devices have the defect of not being intelligent. On the one hand, they cannot intelligently detect formaldehyde leakage on large-scale equipment. Generally, they are fixedly installed or manually carried to a specific location for detection, and cannot intelligently determine a specific location. Leakage problem, on the other hand, requires manual installation and fixing of detectors. It is obviously unrealistic to install the above-mentioned equipment in workshops where formaldehyde leakage may occur. Therefore, formaldehyde alarm detection equipment urgently needs to be intelligently improved in the above aspects
