Description
Technical Field
The utility model relates to an environment check out test set technical field, concretely relates to dust concentration test and alarm device based on STM32 that refractory material mill dust concentration detected and reported to police.
Background
Along with the rapid development of the information era, intellectualization increasingly becomes the mainstream trend of the development of the era, and meanwhile, a large amount of dust exists in workshops of refractory material factories, and if the dust cannot be timely and effectively detected and discharged, the life health safety of workers can be seriously threatened. Therefore, the intelligent detection capability of the dust content in the workshop environment becomes one of the important indexes for evaluating the intellectualization of the workshop. Therefore, timely and sensitive detection of dust concentration in factories becomes a very important task, especially in some refractory factories, which are in a high temperature state for a long time, and since a large amount of dust is generated by high-temperature calcination, a dust measuring device with high sensitivity is needed, which can accurately measure the dust concentration and can timely give an alarm and perform treatment. However, in terms of the existing dust measuring device, many factories adopt direct measurement methods, sampling is carried out by using a sampler, and then detection is carried out by using a biological method, the method is complex to operate, the time required by the test is long, the situation of the dust concentration on site cannot be detected at any time, meanwhile, the dust concentration is influenced by many factors such as emission sources and weather, the change is very rapid, and the direct test method cannot meet the requirement.
Disclosure of Invention
The utility model aims at providing a can be very big improvement the sensitivity of dust concentration test and accuracy based on STM32 dust concentration test and alarm device.
The invention is realized by the following technical scheme:
the utility model discloses a dust concentration test and alarm device based on STM32, a serial communication port, include the dust collector who comprises dust removal exhaust fan and atomizer, its characterized in that still includes singlechip STM32, AD converter, alarm, display and the power that is connected with singlechip STM32 respectively, the signal amplification circuit who is connected with the AD converter, the gas sensor who is connected with signal amplification circuit, the power still is connected with gas sensor, singlechip STM32 still with dust collector's dust removal exhaust fan and atomizer electric connection.
Further, the gas sensor is arranged in a production workshop of a refractory material factory and used for detecting the dust concentration.
Furthermore, the alarm is an audible and visual alarm, and comprises a buzzer and an alarm indicator light.
Further, the exhaust fan and the sprayer are installed at the top and one side of a production workshop of a refractory material factory and are used for reducing the dust concentration.
Further, the A/D converter is an ADS1256 converter.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a STM32 microprocessor, very big improvement the sensitivity and the accuracy of dust concentration test, the very big improvement of audible-visual annunciator of adoption in the past the unobvious defect of device warning, the dust collector that sets up can in time adjust the humidity of mill's air after the alarm sends the police dispatch newspaper to the control air discharge fan removes dust, has greatly improved the injury that the dust concentration of mill caused to the staff. The use of converter ADS1256 has improved conversion rate and precision greatly, and simultaneously, the device low in production cost, installation and maintenance are convenient, and intelligent level is high, great improvement the accuracy and the sensitivity of dust concentration test.
Drawings
Fig. 1 is the utility model discloses a dust concentration test and alarm device block diagram based on STM 32.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, but the embodiments of the invention are not limited thereto.
The utility model discloses a dust concentration test and alarm device based on STM32, its characterized in that, include the dust collector who comprises dust removal air discharge fan and atomizer, its characterized in that still includes singlechip STM32, the A/D converter, alarm, display and the power that are connected with singlechip STM32 respectively, the signal amplification circuit who is connected with the A/D converter, the gas sensor who is connected with the signal amplification circuit, the alarm be audible-visual annunciator, including bee calling organ and alarm indicator; the power still is connected with gas sensor, singlechip STM32 still with dust collector's dust removal air discharge fan and atomizer electric connection.
The utility model discloses be provided with signal amplification circuit between gas sensor and AD converter, but the dust concentration signal of gas sensor collection can be outgassed through signal amplification circuit to in the more accurate information that obtains dust concentration, gas sensor set up in the workshop of refractory material mill, be used for detecting dust concentration, converter ADS 1256's use has improved conversion rate and precision greatly.
Exhaust fan and atomizer install at the workshop top and one side of refractory material mill for reduce dust concentration. When the dust concentration is more than or equal to 10 mg/m, the alarm gives an alarm, otherwise, the alarm is not given, after the audible and visual alarm gives an alarm, the fan and the dust removal device of the dust removal module are started to start dust removal, air is humidified and cooled, and meanwhile, the display always displays the concentration value in the whole test.
