Description

Technical Field

[0001] The present invention relates to the technical field of cement curing, and in particular to a monitoring and management system applied to a constant-temperature standard curing box for cement test blocks. Background Art

[0002] Accurately monitoring and controlling humidity within a constant-temperature standard curing chamber for cement specimens is crucial in its design and use. Traditionally, a single humidity sensor has been installed within the chamber, but this approach has limitations. Because humidity distribution can be uneven within the chamber, a single sensor cannot fully reflect humidity conditions throughout the entire space. To address this issue, the industry has begun installing multiple humidity sensors at various locations within the chamber to monitor humidity changes in each area. By averaging or weighting the data from multiple sensors, more accurate and comprehensive overall humidity information can be obtained.

[0003] However, this improved approach still faces some challenges. In particular, large temperature differences between the inside and outside of the chamber can lead to condensation. This condensation can create localized areas of high humidity within the chamber, affecting the sensor's measurement accuracy. The presence of condensation can cause localized variations in humidity within the sensor's environment, making it impossible for the sensor to accurately capture the actual humidity level throughout the chamber. This phenomenon not only affects the accuracy of humidity control but can also adversely affect the standard curing process for the cement specimens, further compromising the reliability of the test results.

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Reference Figures 1 to 3 The present invention proposes a monitoring and management system for a constant temperature standard curing box for cement test blocks, the system comprising: an internal temperature detection module 10, an external temperature detection module 20, a controller 30, a switch module 40, and a plurality of humidity sensors 50; The controller 30 is respectively connected to the internal temperature detection module 10, the external temperature detection module 20, and the switch module 40. The switch module 40 is respectively connected to the plurality of humidity sensors 50 and a power supply. The plurality of humidity sensors 50 are distributed at different positions in the constant temperature standard curing box for cement test blocks to monitor the humidity in different areas. The in-box temperature detection module 10 is used to detect the ambient temperature in the curing box and output an in-box temperature electrical signal corresponding to the ambient temperature to the controller 30; The external temperature detection module 20 is used to detect the ambient temperature outside the curing box and output an external temperature electrical signal corresponding to the ambient temperature to the controller 30; The controller 30 is configured to calculate the difference between the voltage value corresponding to the internal temperature electrical signal and the voltage value corresponding to the external temperature electrical signal, and output a shut-off signal of the humidity sensor 50 on the inner wall of the box to the switch module 40 when the difference is greater than a preset temperature difference; The switch module 40 is used to disconnect the humidity sensor 50 located on the inner wall of the box from the power supply when receiving a shutdown signal from the humidity sensor 50 on the inner wall of the box; The humidity sensor 50 is used to detect the ambient humidity of various parts of the curing box when the power supply is turned on, and output an electrical signal corresponding to the ambient humidity to the controller 30; The controller 30 is further used to determine the ambient humidity data of each part in the curing box based on the electrical signal corresponding to the ambient humidity, and to average or weight the ambient humidity data of each part, and to adjust the humidity in the curing box based on the processed ambient humidity data.

[0021] It should be noted that the function of the in-box temperature detection module 10 is to detect the ambient temperature in the constant temperature standard curing box for cement test blocks. Its function is to convert the detected in-box ambient temperature into a corresponding in-box temperature electrical signal and output the signal to the controller 30. The function of the out-box temperature detection module 20 is to detect the ambient temperature outside the constant temperature standard curing box for cement test blocks. Its function is to convert the detected out-box ambient temperature into a corresponding out-box temperature electrical signal and output the signal to the controller 30. The function of multiple humidity sensors 50 is to be distributed at different positions in the curing box and to detect the ambient humidity in each area of ​​the box. Its function is that when the power supply connection is turned on, the humidity sensor 50 detects the ambient humidity at the corresponding position, converts it into a corresponding humidity electrical signal, and outputs it to the controller 30. The controller 30 serves as the core control unit of the system, responsible for data processing and decision control. Its function is to receive the temperature electrical signals from the in-box temperature detection module 10 and the out-box temperature detection module 20, and calculate the difference between the corresponding voltage values ​​of the two. When the temperature difference exceeds the preset temperature difference, a shutdown signal is output to the switch module 40 for the humidity sensor 50 on the inner wall of the cabinet to prevent condensation from affecting the sensor's measurement accuracy. The switch module 40 receives the humidity electrical signal from the humidity sensor 50 and determines the ambient humidity data for each location within the curing cabinet. The humidity data for each location is averaged or weighted to generate overall humidity data. Based on the processed humidity data, a control signal is output to adjust the humidity within the curing cabinet. The switch module 40 controls the power connection between the humidity sensor 50 and the power supply. Upon receiving a shutdown signal from the controller 30 for the humidity sensor 50 on the inner wall, the switch module disconnects the humidity sensor 50 located on the inner wall from the power supply to prevent condensation from affecting the sensor's normal operation. The switch module maintains power to other humidity sensors 50 to continue monitoring humidity in other areas of the cabinet. The power supply provides the necessary operating power for the humidity sensors 50. The switch module 40 controls the power supply to humidity sensors 50 at different locations, ensuring their normal operation. The temperature detection module works in conjunction with the controller 30 to monitor and calculate the temperature difference between the inside and outside of the cabinet in real time. Controller 30 uses temperature and humidity data to determine whether to shut down certain sensors to prevent condensation from affecting measurement accuracy. Switch module 40 controls the power supply to humidity sensor 50 based on instructions from controller 30, ensuring system stability and reliability. The entire system forms a closed loop, accurately monitoring and automatically adjusting the humidity in the cement block constant temperature standard curing chamber based on actual environmental changes.

[0022] Furthermore, the system further comprises: a status display module 60; The status display module 60 is connected to the controller 30; The controller 30 is further configured to output a status display signal to the status display module 60 when the humidity sensor 50 on the inner wall of the box is disconnected from the power supply; The status display module 60 is configured to display the disconnection status of the humidity sensor 50 on the inner wall of the box when receiving the status display signal.

[0023] It should be noted that the status display module 60 is used to display the operating status of each key component of the system in real time, particularly the power supply status of the inner wall humidity sensor 50. It connects to the controller 30 and receives status display signals from the controller 30. When the inner wall humidity sensor 50 is disconnected from the power supply, the controller 30 outputs a status display signal to the status display module 60. Upon receiving the status display signal, the status display module 60 displays the disconnected status of the inner wall humidity sensor 50, alerting the user that the sensor has been de-energized, possibly due to condensation caused by a large temperature difference between the inside and outside of the cabinet. The status display module 60 in the system serves a monitoring and feedback function: it provides intuitive feedback on system operation, allowing users to understand the real-time status of the inner wall humidity sensor 50. Abnormality alerts: When a large temperature difference between the inside and outside of the cabinet is detected, indicating that the sensor may be affected by condensation, the system will proactively disconnect the power supply to the relevant sensor. The status display module 60 will immediately display this status, alerting the user to possible environmental changes. User operation guidance: Through the status display module 60, the user can obtain the working status of the sensor in a timely manner, and take further actions as needed, such as checking the environmental conditions or adjusting the system settings. The status display module 60 works in synergy with other modules. When the system detects that the temperature difference between the inside and outside of the box is too large, resulting in a potential risk of condensation, the controller 30 will disconnect the power supply connection of the humidity sensor 50 on the inner wall of the box and send a status display signal to the status display module 60. After receiving the signal, the status display module 60 immediately displays the disconnection status, and the user can understand the power supply status and working status of the sensor in real time. This design ensures the transparency of the system and the user's timely grasp of the system operation status, further improving the system reliability and user experience. By adding the status display module 60, the entire system is more intelligent and user-friendly, and can provide timely feedback and prompts when problems arise, helping users to better manage and maintain the operation of the cement test block constant temperature standard curing box.

[0024] Furthermore, the system further comprises: a wireless communication module 70; The wireless communication module 70 is connected to the controller 30 and the terminal device respectively; The controller 30 is further configured to output a humidity sensor 50 disconnection signal to the wireless communication module 70 when the humidity sensor 50 on the inner wall of the box is disconnected from the power supply; The wireless communication module 70 is configured to send the humidity sensor 50 disconnection signal to the terminal device via wireless transmission upon receiving the humidity sensor 50 disconnection signal.

[0025] It should be noted that the wireless communication module 70 is used to enable wireless communication between the system and external terminal devices, transmitting key status information to the user in real time. It connects to the controller 30 and receives various signals from it, including a disconnection signal from the humidity sensor 50 when the inner wall humidity sensor 50 is disconnected from the power supply. The wireless communication module 70 wirelessly transmits the disconnection signal to the user's terminal device (such as a mobile phone, tablet, or computer). This allows users to remotely monitor the status of the curing box in real time and receive prompt alerts or notifications when problems arise. The wireless communication module 70 in the system enables remote monitoring: Through the wireless communication module 70, users can obtain real-time status information about the cement block constant temperature standard curing box without having to visit the site. This greatly facilitates remote monitoring and management of the equipment. Timely alarms: When the system detects an excessive temperature difference between the inside and outside of the box and automatically disconnects the power supply to the humidity sensor 50, it immediately sends an alarm to the user terminal via the wireless communication module 70, ensuring that users are promptly informed and can take appropriate measures. Data Transmission: In addition to abnormality alarm information, the system can also transmit daily operating data via the wireless communication module 70, allowing users to remotely access and analyze key parameters such as the curing chamber's temperature and humidity. The wireless communication module 70 works in conjunction with other modules, enabling the controller 30 to monitor and determine the temperature and humidity conditions within the system. When an abnormality is detected and the power to the chamber's inner wall humidity sensor 50 is disconnected, the controller 30 sends a disconnection signal to the wireless communication module 70. Upon receiving the disconnection signal, the wireless communication module 70 transmits the information to the user's terminal device via the wireless network. Users can access this information in real time through their terminal device and remotely monitor system operation. After receiving the information, the terminal device can perform remote operations or on-site inspections as needed, further enhancing system safety and reliability. The introduction of the wireless communication module 70 not only provides powerful local monitoring and automated adjustment capabilities, but also expands remote monitoring and management capabilities. This is a very useful feature for users who frequently monitor multiple curing chambers or cannot operate on-site for extended periods. This further enhances the overall system's intelligence and significantly improves the user experience.

[0026] Furthermore, the system further comprises: an alarm module 80; The alarm module 80 is connected to the controller 30; The controller 30 is further configured to calculate the difference between the voltage value corresponding to the internal temperature electrical signal and the voltage value corresponding to the external temperature electrical signal, and output an alarm signal to the alarm module 80 when the difference is greater than a preset maximum temperature difference; The alarm module 80 is used to issue an alarm when receiving the alarm signal if the temperature difference between the temperature inside the box and the temperature outside the box is too large.

[0027] It should be noted that the alarm module 80 is designed to issue an alarm to the user when the temperature difference between the inside and outside temperatures exceeds a preset maximum, allowing the user to promptly address any potential abnormalities. It connects to the controller 30 and receives alarm signals from it. When the controller 30 detects that the difference between the voltage corresponding to the internal and external temperature signals exceeds a preset maximum temperature difference, the controller 30 sends an alarm signal to the alarm module 80. Upon receiving the alarm signal, the alarm module 80 immediately issues an audible, visual, or other form of alarm to notify the user of the excessive temperature difference between inside and outside the chamber, potentially impacting the normal operation of the system or causing environmental control failure. The role of the alarm module 80 in the system is as follows: Abnormal notification: The alarm module 80 is a key safety mechanism in the system, providing timely alarms when the temperature difference between inside and outside the chamber is excessive, preventing system failures or cement block curing quality issues caused by such a large temperature difference. User notification: Through the alarm module 80, the system promptly notifies the user of any abnormalities, prompting the user to take swift action and avoid further problems. Diverse Alarm Methods: The alarm module 80 can communicate alarm information through various means (such as sound, light, and on-screen prompts), ensuring that users receive timely alerts in a variety of environments. The alarm module 80 works in conjunction with other modules, enabling the controller 30 to monitor and calculate temperature signals inside and outside the chamber. When the temperature difference exceeds a preset safety threshold, the controller 30 generates an alarm signal and sends it to the alarm module 80. Upon receiving the signal, the alarm module 80 immediately triggers an alarm device, notifying the user through audible and visual alarms or other means, reminding the user that the temperature difference requires immediate inspection and adjustment. This alarm mechanism, combined with the wireless communication module 70 and the status display module 60, synchronizes local alarms with remote notifications, further ensuring system security and reliability. The addition of the alarm module 80 enhances system security and responsiveness. Users can quickly receive system alerts in the event of an abnormally large temperature difference, allowing them to take necessary measures to protect the curing quality of the cement test blocks and the normal operation of the system. This design significantly enhances the system's intelligence and user experience, making the entire monitoring and management system more comprehensive and reliable.

[0028] Furthermore, the system further comprises: a voltage dividing module 90 and a voltage stabilizing module 100; The voltage dividing module 90 is connected to the power supply and the voltage stabilizing module 100 respectively, and the voltage stabilizing module 100 is connected to the internal temperature detection module 10 and the external temperature detection module 20 respectively; The voltage dividing module 90 is used to divide the power voltage provided by the power supply to obtain a divided voltage, and send the divided voltage to the voltage stabilizing module 100; The voltage stabilizing module 100 is used to stabilize the divided voltage and send the stabilized divided voltage to the internal temperature detection module 10 and the external temperature detection module 20; The box temperature detection module 10 is further used to adjust the divided voltage after stabilization to obtain the box temperature electrical signal; The external temperature detection module 20 is further configured to adjust the stabilized divided voltage to obtain the external temperature electrical signal.

[0029] It should be noted that the voltage divider module 90 is responsible for reducing the power supply voltage to a level suitable for use by other parts of the system, preventing damage to system components caused by excessive voltage. The voltage regulator module 100 ensures the stability of the system's supply voltage, preventing voltage fluctuations from affecting the accuracy and reliability of the temperature detection module. Stable voltage input is crucial for accurate temperature detection, especially in applications requiring precise measurement. Through precise voltage control, the temperature detection module can operate more stably, ensuring the accuracy of internal and external temperature measurements, thereby providing reliable data support for other system functions (such as triggering the alarm module 80). The voltage divider module 90 and the voltage regulator module 100 work in synergy with other modules. The power supply provides the original voltage, which the voltage divider module 90 reduces to a level suitable for system use. The voltage regulator module 100 further stabilizes the divided voltage to ensure that the voltage received by the temperature detection module is not affected by fluctuations. The internal and external temperature detection modules 10 and 20 use this stabilized voltage to measure temperature and feed the temperature signal back to the system for further processing (such as temperature difference calculation and alarm signal generation by the controller 30). By introducing the voltage divider module 90 and the voltage regulator module 100, the system's power management capabilities are significantly enhanced. This not only improves system stability and reliability, but also ensures that the temperature detection module receives an accurate and stable power supply during measurement, thereby improving the measurement accuracy and response speed of the entire system. This is a crucial improvement for the overall system performance and user experience.

[0030] Furthermore, the box internal temperature detection module 10 includes: a first resistor R1, and the box external temperature detection module 20 includes: a second resistor R2, and the first resistor R1 and the second resistor R2 are thermistors; The first end of the first resistor R1 is connected to the power supply through the voltage stabilizing module 100 and the voltage dividing module 90 , and the second end of the first resistor R1 is connected to the controller 30 ; A first end of the second resistor R2 is connected to the power supply through the voltage stabilizing module 100 and the voltage dividing module 90 , and a second end of the second resistor R2 is connected to the controller 30 .

[0031] It should be noted that when the temperature inside and outside the box changes, the resistance values ​​of the first resistor R1 and the second resistor R2 will change accordingly. Since these two thermistors are connected between the stabilized power supply voltage and the controller 30, the controller 30 can calculate the corresponding temperature signals by detecting changes in the current or voltage passing through the thermistors. These temperature signals are used for subsequent functions such as temperature difference calculation and alarm triggering. The thermistors are directly involved in temperature detection and are key components in generating temperature signals in the system. By monitoring changes in resistance value, the system can accurately measure the temperature inside and outside the box. The stable voltage provided by the voltage stabilization module 100 allows the thermistors to more accurately reflect temperature changes, ensuring the accuracy of temperature measurement. The temperature signals generated by the thermistors provide the necessary data input for the controller 30, which uses these signals to calculate temperature differences and identify abnormal conditions. The thermistors work synergistically with other system modules, including the voltage divider module 90 and the voltage stabilization module 100, to provide the thermistors with a stable operating voltage, ensuring the reliability of their output signals. The controller 30 receives the temperature signals from the thermistors, analyzes and processes them, and determines whether to trigger an alarm or adjust system parameters. Alarm module 80 determines whether to issue an alarm for excessive temperature differences based on the controller 30's analysis of the thermistor signal. By using thermistors in the internal and external temperature detection modules, the system can accurately detect temperature changes inside and outside the enclosure. Combined with the voltage stabilization module 100 and the voltage divider module 90, this design ensures accurate and stable temperature measurement, further enhancing the system's reliability and intelligence. This makes the entire system more efficient in temperature monitoring and exception handling, providing users with reliable operational assurance.

[0032] Furthermore, the voltage dividing module 90 includes: a third resistor R3, a fourth resistor R4, a fifth resistor R5 and a sixth resistor R6; Wherein, a first end of the third resistor R3 is connected to the power supply, a second end of the third resistor R3 is connected to a first end of the fourth resistor R4, and a second end of the fourth resistor R4 is grounded; A first end of the fifth resistor R5 is connected to the power supply, a second end of the fifth resistor R5 is connected to a first end of the sixth resistor R6, and a second end of the sixth resistor R6 is grounded.

[0033] It should be noted that, through the voltage divider circuit formed by the third resistor R3, the fourth resistor R4, the fifth resistor R5, and the sixth resistor R6, the voltage divider module 90 can effectively reduce the power supply voltage to the operating voltage range required by various components of the system. This design not only ensures the flexibility and stability of the system power supply, but also provides a good foundation for subsequent voltage stabilization and temperature detection, ensuring that the entire system can operate at an accurate and stable voltage.

[0034] Furthermore, the voltage stabilizing module 100 includes: a first capacitor C1 and a second capacitor C2; Wherein, the first end of the first capacitor C1 is connected to the second end of the third resistor R3 and the first end of the fourth resistor R4, and the second end of the first capacitor C1 is grounded; A first end of the second capacitor C2 is connected to the second end of the fifth resistor R5 and the first end of the sixth resistor R6 , and a second end of the second capacitor C2 is grounded.

[0035] It should be noted that by introducing the first capacitor C1 and the second capacitor C2 into the voltage stabilization module 100, forming an RC filter circuit with the voltage divider circuit, the system can effectively filter out high-frequency noise and fluctuations in the voltage, providing a more stable power supply voltage. This design not only enhances the measurement accuracy of the temperature detection module and the overall stability of the system, but also ensures reliable operation of the system in various operating environments.

[0036] Furthermore, the switch module 40 includes: a plurality of first switch tubes Q1 and a plurality of seventh resistors R7; Among them, the control ends of multiple first switching tubes Q1 are connected to the controller 30, the input ends of multiple first switching tubes Q1 are connected to the first ends of multiple seventh resistors R7, the second ends of multiple seventh resistors R7 are connected to the power supply, and the output ends of multiple first switching tubes Q1 are respectively connected to the multiple humidity sensors 50.

[0037] It should be noted that the control terminal (gate or base) of the first switching transistor Q1 (such as a MOSFET or BJT transistor) is connected to the controller 30. The controller 30 can control the switching state of the switching transistor by sending a signal to the control terminal. The input terminal (drain or collector) is connected to the first end of the seventh resistor R7. The output terminal (source or emitter) is respectively connected to the humidity sensor 50 for controlling the power supply to the humidity sensor 50. The first end of the seventh resistor R7 is connected to the input terminal of the first switching transistor Q1. The second end is connected to the power supply. The function of the seventh resistor R7 is to limit the current passing through the first switching transistor Q1, protecting the switching transistor and the subsequent humidity sensor 50 from damage caused by current surges.

[0038] Specifically, the controller 30 sends control signals (e.g., high or low level signals) to the control terminals of multiple first switching transistors Q1. By varying the control signals, the controller 30 controls the on / off switching of the first switching transistors Q1. When the controller 30 applies an on signal to the control terminal of a first switching transistor Q1, the switching transistor is turned on, forming a path between its input and output terminals, allowing current to flow from the power supply through the seventh resistor R7 to the humidity sensor 50, and the humidity sensor 50 begins operation. When the control signal is an off signal, the switching transistor is disconnected, and the humidity sensor 50 loses power and ceases operation. The seventh resistor R7 is used to limit the current flowing through the first switching transistor Q1, preventing transient current from damaging the humidity sensor 50 and the switching transistor. It also serves to limit the operating current of the humidity sensor 50 to a safe range.

[0039] Furthermore, the status display module 60 includes: a light emitting diode; The anode of the light emitting diode is connected to the controller 30 , and the cathode of the light emitting diode is grounded.

[0040] It should be noted that the status display module 60 provides intuitive system status indication via a simple light-emitting diode (LED). The controller 30 controls the LED's on and off to display system operating status or events to the user. This design is simple and effective, providing users with timely and clear system status feedback.
