Description

Technical Field

[0001] This invention relates to the field of environmental monitoring equipment technology, and in particular to an automatic alarm device for preventing heatstroke. Background Technology

[0002] Heatstroke, also known as severe heat exhaustion, is a serious clinical syndrome caused by exposure to hot and humid environments, which leads to a rapid increase in the body's core temperature, exceeding 40°C, accompanied by burning skin, altered consciousness (such as delirium, convulsions, and coma), and damage to multiple organ systems.

[0003] Metallic and colored backgrounds in the environment can increase the ambient temperature through significant heat reflection, and can also release harmful elements, such as lead, mercury, and arsenic in the colors, under high temperatures. Workers who work in high-temperature environments for extended periods are more susceptible to heatstroke. Therefore, a portable device is needed to monitor the temperature in the work environment at all times and promptly alert workers to evacuate when the temperature reaches a set value, thus preventing workers from developing heatstroke due to prolonged exposure to high temperatures. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-6 As shown, an automatic alarm device for preventing heatstroke includes a rear shell 1, a front cover 3 fixed to the front side of the rear shell 1, and two symmetrical lifting lugs 2 fixed to the upper end of the rear shell 1 for easy hanging with ropes. A fixing buckle 11 is fixed to the inner wall of the rear shell 1, and a main board 13 is fixed to the fixing buckle 11. The main board 13 uses an STC89C51 microcontroller. The STC89C51 is an 8051 core ISP (In-System Programmable) chip with a maximum operating clock frequency of 80MHz. It contains 8KBytes of Flash read-only programmable memory that can be repeatedly erased and rewritten 1000 times. The device is compatible with the standard MCS-51 instruction set and 80C51 pin structure. The chip integrates a general-purpose 8-bit central processing unit and an ISP Flash memory unit, and has in-system programmable (ISP) characteristics. A battery 16 is fixed at the bottom to provide power. A display screen 8 is embedded at the upper part of the front surface of the front cover 3 to display the ambient temperature, humidity and time information. An indicator light 9 and a control button 7 are set below the display screen 8. A speaker 6 is set in the middle of the front surface of the front cover 3 to emit voice reminders. A buzzer 17 is fixed on the inner wall of the front cover 3 to one side of the speaker 6 to emit simple sound reminders. A temperature sensor 4 and a humidity sensor 5 are embedded on the lower surface of the front cover 3. The temperature sensor 4 is a PT100 and the humidity sensor 5 is an HR202. A timer 15 is fixed on the main board 13. The temperature sensor 4, humidity sensor 5, speaker 6, control button 7, display screen 8, indicator light 9, timer 15, and buzzer 17 are electrically connected to the main board 13 and the battery 16.

[0024] In this embodiment, at least one fixing hole 12 is formed on the rear wall of the rear shell 1 for easy fixing with screws, and at least two magnetic pieces 10 are embedded in the rear wall of the rear shell 1 for easy fixing with magnetic attraction. Multiple fixing methods are convenient for use in different work spaces.

[0025] In this embodiment, a locator 18, which is electrically connected to the motherboard 13 and the battery 16, is fixed on the inner wall of the front cover 3. The locator 18 is a MAP76 model, which facilitates the confirmation of the device's position.

[0026] In this embodiment, a wireless signal transmitter 14 electrically connected to the motherboard 13 is fixed on the motherboard 13. If the device does not move within a set time after multiple alarms, the wireless signal transmitter 14 can transmit an alarm signal to a remote monitoring center, which will facilitate the staff of the monitoring center to promptly arrange for someone to go to the site to check the status of the staff in the workspace. In the event of heatstroke fainting, it can be detected and treated in a timely manner.

[0027] In this embodiment, a lighting lamp 19 electrically connected to the motherboard 13 is embedded on the rear shell 1, which facilitates temporary lighting for the rechargeable flashlight.

[0028] The working principle of this invention is as follows: During use, the device is fixed in the workspace by rope suspension, screw fixing, or magnetic attraction. Temperature sensor 4 automatically detects the temperature in the workspace, and humidity sensor 5 automatically detects the humidity. When the temperature in the workspace exceeds 45°C, the first alarm is triggered. The main board 13 controls the buzzer 17 to sound, and the indicator light 9 flashes red to alert personnel and prompt them to evacuate. When the temperature in the workspace rises to 56°C, the second alarm is triggered. When the temperature in the workspace rises to 64.4°C, the third alarm is triggered. The position of the device can be automatically detected by the locator 18. When the first alarm sounds... If the device does not move within one hour, half an hour after the second alarm, or ten minutes after the third alarm, the mainboard 13 controls the speaker 6 to issue a voice reminder to evacuate staff to a safe area as soon as possible. At the same time, it sends an alarm signal to the remote monitoring center via the wireless signal transmitter 14, allowing staff at the remote monitoring center to promptly go to the site to understand the cause of the alarm and guide personnel in the workspace to evacuate, reducing the probability of heatstroke among staff in the workspace. In addition, it can combine temperature and humidity information to comprehensively assess the probability of heatstroke caused by the workspace environment, thereby shortening the alarm time when the temperature and humidity are high, further preventing staff from suffering from heatstroke.

[0029] The circuit connection involved in this invention is a conventional method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0030] Components not described in detail in this article are existing technologies.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
