Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air pollution alarm system for warning of concentrations within dangerous ranges in facilities and areas where the incorporation of specific substances into the air is regulated.

BACKGROUND OF THE INVENTION In recent years, improvements have been made in the management of living environments and workplace environments in companies, and in particular, many measures have been taken to prevent environments that are dangerous or harmful to health.

Furthermore, in the manufacturing environment of companies, environmental improvement management to improve quality is being carried out mainly at semiconductor and chemical production sites.

One way to improve the environment is to constantly detect the concentration of harmful substances in the air using an air pollution alarm device.When a predetermined standard concentration is reached, an alarm sounds and immediate measures are taken to improve the environment. However, there are ways to prevent such harm from occurring.

Conventional air pollution alarm devices of this type include a memory unit that stores a reference concentration of a harmful substance, and a control that calculates the concentration of this target substance in the air in the current environment and compares it with a certain reference concentration. The controller is equipped with a display section that displays the calculation results of this control section, and an alarm section that issues an alarm when the calculation results exceed the standard concentration. It is configured so that it can be done.

FIG. 2 shows the configuration of a conventional air pollution alarm device.

As shown in FIG. 2, as a component, 47 is a memory section in which the reference concentration of a certain substance is stored.

48 is a control unit υ, which includes a detection unit 49 for measuring the concentration of this substance in the air and an arithmetic comparison unit 60 for calculating the concentration of the eight forces of the detection unit 49 and comparing it with a reference concentration. It is configured. Reference numeral 61 is a display section for displaying the calculation results of the arithmetic comparison section 50. Reference numeral 62 denotes an alarm section that issues an alarm when the calculated result exceeds the reference concentration stored in the memory section 47.

Next, the related operations of the constituent elements of the above-mentioned conventional example will be explained. In FIG. 2, when the detection unit 49 detects a target substance in the air, the calculation and comparison unit 50 calculates the concentration of the target substance.

Thereafter, the reference concentration of the target substance is transferred from the memory section 47 to the calculation comparison section 5o, and the calculation result is compared with the reference concentration in the calculation comparison section 50.

By comparison, when the calculation result exceeds the standard concentration,
A warning signal is sent from the control section 48 to the alarm section 52. The alarm section 52 issues an alarm upon receiving this warning signal.

In this way, the conventional air pollution alarm device described above can issue an alarm for only one target substance whose concentration exceeds the standard concentration.

Problems to be Solved by the Invention However, the conventional air pollution alarm device described above only issues an alarm for one standard concentration of one target substance, and cannot handle multiple target substances. There was a problem in that the reference concentration could not be changed depending on the usage environment.

The present invention solves these conventional problems,
It is an object of the present invention to provide an excellent air pollution alarm device that can separately set reference concentrations for a plurality of target substances.

Means for Solving the Problems In order to achieve the above object of the present invention, an input section for inputting a plurality of different target substances and their respective reference concentration levels to be detected, and input information input to the input section are provided. a memory unit for storing information, a control unit for detecting that a target substance exceeding the above-mentioned reference concentration level has occurred in the current environment among the plurality of different input target substances; It consists of a display section that displays the concentration, and an alarm section that issues an alarm at the same time as this display.In the input section, multiple sets of target substances to be detected and their reference concentration levels can be registered in sequence. It is also an air pollution alarm device that displays target substances and their concentrations that exceed the reference concentration level on the display section, and issues an alarm from the alarm section.

Operation The air pollution alarm device of the present invention having the above configuration can generate an alarm by inputting a target substance whose concentration is desired to be detected and a reference concentration to be detected based on the air concentration of the target substance as a set into the input section. Multiple sets of data can be input in sequence, and based on this input data, target substances that have reached the standard concentration of sulfur are displayed and an alarm is issued. That is, the control unit constantly detects the concentration of each of a plurality of registered target substances in the air, and detects target substances exceeding the reference concentration level set for each target substance.

Based on the 8 forces of the control section, the detected target substance and its concentration are displayed on the display section, and an alarm is issued by the alarm section.

In addition, an analysis program is stored in the memory unit, and based on this analysis program, data regarding multiple target substances in the air detected in the control unit is processed, and the extraction and concentration level of the target substances are simultaneously compared.
