[0048] Specifically, in the above embodiment, the power supply module includes a lithium battery and a charging management circuit; the lithium battery is connected to the control module for power supply; and the charging management circuit is connected to the lithium battery for charging the lithium battery.

[0049] In this embodiment, the power supply module is specifically powered by a rechargeable lithium battery, which has a long battery life and stable power output, and may also include a charging management circuit that can charge the lithium battery safely and efficiently.

[0050] Further, such as Figure 2 As shown, the power supply module also includes a voltage conversion unit, a voltage stabilizing unit, a protection circuit, an external power supply unit and a battery management unit; the output end of the lithium battery is connected to the control module through the protection circuit, the voltage stabilizing unit and the voltage conversion unit in sequence; the output end of the external power supply unit is connected to the input end of the voltage conversion unit for connecting to an external power supply to supply power to the control module; the battery management unit is connected to the lithium battery for monitoring the power supply status of the lithium battery.

[0052] Specifically, in the above embodiment, the alarm module includes a buzzer and / or an indicator light; when the control module detects that the environmental monitoring parameter exceeds the preset environmental parameter threshold, the control module controls the buzzer to sound an alarm; and / or the control module controls the indicator light to flash.

[0053] In the present embodiment, the alarm module adopts a design method of either a buzzer or an indicator light or both, which can provide immediate visual and auditory warnings when the environmental monitoring parameters exceed the preset threshold value; specifically, when the environmental monitoring parameters exceed the threshold value, the buzzer and / or the indicator light can immediately sound an alarm to remind the user to take action. The immediate feedback helps to respond quickly to potential dangerous situations and reduce reaction time. In addition, the alarm is issued by combining sound and vision, which can more effectively attract the user's attention.

[0055] Furthermore, the microcontroller chip is also provided with an extended data transmission port for connecting to external expansion devices or other sensors.

[0056] In this embodiment, a high-performance embedded microcontroller chip is selected, which has powerful processing capabilities and rich peripheral resources, and can meet various functional requirements of the environmental monitor. For example, a microcontroller with a 32-bit ARM core has high operating speed and low power consumption. Specifically, the 32-bit microcontroller chip is STM32F103C5T6-LQFP-48, in which the GND ground pin and the +3.3V power pin are used as the power start control bit of the OLED12864 liquid crystal display in the display module, and the stable operation of the display is ensured through precise power control. At the same time, the PB12 of the chip The I / O port and PB13 I / O port are used as display data transmission ports to effectively control the data of the OLED12864 liquid crystal display screen, so as to realize the accurate display of the actual parameter values ​​of each measured acquisition; in terms of the key port, the PB5 port, the PB8 port and the PB9 port are respectively the manual threshold setting key interface, which play an important role. Specifically, they can be used to modify the set values ​​of various measured parameters, including the threshold increase key interface and the threshold decrease key interface, which is convenient for users to flexibly adjust the alarm threshold according to actual needs; and the sensor data transmission port is used as the sensor data bit access, and the PA7 port is used as the data bit access port of the smoke sensor and the carbon monoxide sensor respectively, which can accurately receive the data collected by these two sensors.

[0057] Among them, as a microcontroller based on the ARM Cortex-M3 core, the STM32F103C5T6-LQFP-48 has the characteristics of high performance. Its maximum main frequency can reach 72MHz, with high computing speed and powerful processing power. It can quickly process various environmental parameter data, and has excellent performance in low power consumption. It adopts advanced low-power technology, has low power consumption and excellent power consumption management capabilities, and is suitable for application in various embedded systems, especially for battery-powered environmental monitors, which can extend the use time of the equipment; and the rich peripheral resources give it a great advantage in environmental monitoring. It supports a variety of communication interfaces, such as SPI, I2C, UART, etc., which is convenient for data communication and integration with other devices. It also has multiple timers and PWM outputs and other peripherals to meet different control requirements. In addition, large-capacity storage is also a highlight of the chip. It has 64KB Flash memory and 20KB RAM memory, which can meet the needs of large-capacity data storage and can store a large amount of environmental parameter data and program code; a variety of packaging forms can provide more choices, suitable for different application scenarios, whether in small embedded devices or in more complex systems, you can find a suitable packaging form, which brings greater flexibility to design and application.

[0058] Among them, the display module specifically adopts an OLED display screen, which has the advantages of high contrast, low power consumption, and fast response speed. It can clearly display environmental parameter information, such as temperature, humidity, air pressure, light intensity, smoke concentration, carbon monoxide content, etc. It can also display time, date, alarm information, etc., so that users can understand the working status of the environmental monitor conveniently; specifically, the OLED12864 liquid crystal display is a widely used display device that adopts organic light emitting diode technology, also known as organic electric laser display. Its self-luminous characteristics make it unnecessary for a backlight source. It adopts a thin organic material coating and a glass substrate. When current passes through, these organic materials will emit light, and the OLED12864 display screen has the advantages of a large viewing angle and low power consumption.

[0059] Specifically, in the above embodiment, a data processing unit is provided in the sensor module; the data processing unit is used to receive the original environmental data collected by the sensor module, preprocess and calibrate the original environmental data, obtain environmental monitoring parameters, and send the environmental monitoring parameters to the control module.

[0060] In this embodiment, a data processing unit is provided in the sensor module. Different acquisition functions are set according to sensors with different functions. Taking the temperature data acquisition function as an example, the function name is getTemperature(), and its function is to collect ambient temperature data through the temperature sensor and perform preliminary processing, such as unit conversion, data verification, etc. There are no input parameters, and the output parameter is the ambient temperature value in degrees Celsius. The specific implementation steps are to first initialize the temperature sensor, then send a temperature reading command, then receive the data returned by the temperature sensor, and then verify and process the data, convert it into degrees Celsius, and finally return the processed temperature value. The functions of sensors with other functions are similar to the temperature data acquisition function, and the data processing A data fusion and calibration function is also set in the processing unit. The function name is dataFusionAndCalibration(), which is used to fuse and calibrate the data collected by multiple sensors to improve the accuracy and reliability of environmental parameter measurement. The input parameters are temperature, humidity, air pressure, light intensity, smoke concentration, and carbon monoxide concentration. The output parameters are the fused and calibrated environmental parameter values. The specific implementation steps are to determine the weights of each parameter according to the accuracy and reliability of the sensor, and use algorithms such as weighted average to fuse parameters such as temperature, humidity, and air pressure. Considering the error and drift of the sensor, data calibration is performed, such as temperature compensation and zero point calibration, and finally the fused and calibrated environmental monitoring parameters are returned.

[0061] Specifically, in the above embodiment, the control module is used to receive multiple environmental monitoring parameters sent by the sensor module, and compare each environmental monitoring parameter with the corresponding preset environmental parameter threshold; when any environmental monitoring parameter is greater than the corresponding preset environmental parameter threshold, the control module controls the alarm module to generate alarm information, and sends the alarm information to the display module for display.

[0062] In this embodiment, the control module can set an independent threshold for each environmental monitoring parameter and perform a one-to-one comparison, so as to ensure that each parameter is accurately monitored. By setting different thresholds for different parameters, a multi-level security protection system can be constructed to cover a variety of possible environmental risks. Once any parameter is detected to exceed the preset threshold, the control module can immediately trigger the alarm mechanism and sound an alarm through a buzzer or indicator light to ensure that the user can be informed of the abnormal situation in time. The instant response mechanism reduces the time difference between discovering the problem and taking action, thereby improving the efficiency of the action. In addition to controlling the alarm module to emit sound or light signals, the control module will also generate detailed alarm information and display it through the display module. The user can clearly see which parameter exceeds the normal range and the specific value. The clear alarm information can help the user quickly judge the severity of the problem and make reasonable countermeasures accordingly. By setting reasonable thresholds and independently verifying each parameter, the occurrence of false alarms can be effectively reduced and the accuracy of the alarm can be improved.

[0063] Specifically, in the above embodiment, Figure 3 As shown, a preset data acquisition number times is set in the control module; the control module is used to obtain the environmental monitoring parameters sent by the sensor module and display them through the display module, and record the data acquisition number time; the control module is also used to compare the data acquisition number time with the preset data acquisition number times; when the data acquisition number time reaches the preset data acquisition number times, the control module saves the environmental monitoring parameters and processes the environmental monitoring parameters; when the data acquisition number time does not reach the preset data acquisition number times, the control module controls the sensor module to collect the original environmental data again, and obtains the environmental monitoring parameters sent by the sensor module again, and superimposes the environmental monitoring parameters and the data acquisition number time obtained for multiple times, until the data acquisition number reaches the preset data reading number times, and the control module saves and processes the superimposed environmental monitoring parameters.

[0064] In this embodiment, the specific working process of the control module is as follows: Figure 3As shown in the figure, by superimposing or averaging a certain number of data, data anomalies caused by instantaneous fluctuations or measurement errors can be smoothed out, thereby obtaining more stable monitoring results. The average value after multiple sampling is usually closer to the true value than the result of a single sampling, which helps to improve the accuracy and reliability of the monitoring data. In the process of continuously acquiring multiple data, data points that are obviously deviated from the normal range can be identified and eliminated, thereby ensuring that the final saved and processed data are more effective. By collecting multiple data within a certain period, the changing trends of environmental parameters can be better observed and analyzed, which is very important for predicting possible environmental changes in the future. By reasonably setting the number of data acquisitions, unnecessary data transmission and processing can be reduced while ensuring the quality of monitoring, thereby ensuring that the data meets the needs of users and ensures the validity of the data. If a certain data acquisition fails or the data is abnormal, the system can still make up for it through subsequent multiple acquisitions, which can also ensure the quality of the overall data set. When the number of data acquisitions reaches the preset value, batch processing is performed. Compared with each data acquisition, this method can improve the efficiency of data processing.

[0065] The multifunctional environmental monitoring instrument provided in this application provides strong support for the safety of the nuclear industry environment. It can monitor key parameters such as temperature, humidity, air quality concentration, carbon monoxide gas concentration, smoke concentration, atmospheric pressure and photosensitivity in real time to ensure the safe and stable progress of the nuclear industry production process. On this basis, it can be considered to upgrade the core main control chip to a 64-bit processor chip in the future to further improve the performance of the system. After the frequency of the main control chip is upgraded to 180MHz, the data transmission speed will be greatly improved, and the delay can be shortened to a maximum of 200ms, thereby making the system more efficient and faster in processing large amounts of environmental data, providing stronger technical support for real-time monitoring and rapid response. In addition, the multifunctional environmental monitoring instrument can also be widely used in various industrial production fields. For example, on construction sites, it can monitor environmental parameters in real time to provide construction personnel with a safe and comfortable working environment. By monitoring temperature and humidity, the construction plan can be reasonably adjusted to avoid construction under extreme weather conditions. Monitoring smoke concentration and The concentration of harmful gases can be monitored to detect fire hazards and toxic gas leaks in time to ensure the safety of construction workers. In storage rooms, the temperature, humidity and concentration of harmful gases can be monitored to prevent goods from getting damp, mildewed and corroded by harmful gases. At the same time, by monitoring smoke concentration and fire risks, fire-fighting measures can be taken in time to protect the safety of stored materials. In agricultural vegetable greenhouses, the monitor can monitor parameters such as temperature, humidity, light intensity and carbon dioxide concentration in real time to provide the best environmental conditions for the growth of crops. Through intelligent control of ventilation equipment, irrigation systems and lighting equipment, precision agricultural production can be achieved to improve the yield and quality of crops. In nuclear power plants and thermal power plants, the monitor can monitor parameters such as temperature, humidity, air pressure, concentration of harmful gases and smoke concentration to ensure the safe operation of the power plant. By real-time monitoring of environmental parameters, potential safety hazards can be discovered in time, and corresponding measures can be taken to deal with them to ensure the safety of power plant workers and the stable operation of equipment. Therefore, it has a wide range of application scenarios.
