Description

Technical Field

[0001] This application belongs to the technical field of water level monitoring and early warning, and specifically relates to a two-point water level alarm device. Background Art

[0002] Today, with frequent natural disasters, extreme weather events such as floods and heavy rains pose a huge threat to human society. Timely and accurately monitoring water level changes and taking corresponding early warning measures are of great significance for reducing disaster losses and ensuring people's safety. Traditional water level monitoring methods often have problems such as low accuracy, slow response, and difficult maintenance, making it difficult to meet the needs of modern disaster prevention and mitigation.

[0003] With the progress of technology, float-type water level sensors have gradually been widely used in the field of water level monitoring due to their simple structure, high reliability, and low cost. However, a single water level monitoring method often fails to meet the complex and changeable monitoring requirements, especially in situations where multi-level early warning is required. Utility Model Content

[0004] The purpose of this application is to provide a two-point water level alarm device. By setting two float switches at different heights, multi-level monitoring and early warning of the water level are achieved, which can more accurately reflect the change of the water level and provide more timely and accurate information support for disaster prevention and mitigation work.

[0005] The technical solution adopted by this application to solve the above technical problems is: propose a two-point water level alarm device, including: a first float switch for outputting a first float detection signal when the water level reaches a first threshold;

[0006] A second float switch for outputting a second float detection signal when the water level reaches a second threshold, and the second threshold is greater than the first threshold;

[0007] A control module connected to the first float switch and the second float switch for outputting a first control signal and a second control signal respectively when receiving the first float detection signal and the second float detection signal;

[0008] An alarm system connected to the control module for sounding an alarm when receiving the first control signal and the second control signal;

[0009] A power supply module for providing electrical energy for the float switch assembly and the control module.

[0010] Through the above technical features, when the water level rises to the set first threshold, the floating ball rises due to buoyancy, triggering the internal mechanism of the switch, thereby outputting the first floating ball detection signal, indicating that the water level has reached the primary warning line; when the water level continues to rise to the set second threshold (higher than the first threshold), the second floating ball switch is triggered, outputting the second floating ball detection signal, indicating that the water level has reached a higher warning line, which may mean a more serious flood risk. After receiving the detection signal from the floating ball switch, the control module determines the current water level status according to the source of the signal (the first floating ball or the second floating ball), and outputs corresponding control signals (the first control signal or the second control signal) respectively. To instruct the alarm system to perform corresponding actions, and the alarm system issues different levels of alarms according to the level of the signal (the first control signal or the second control signal) after receiving the control signal from the control module.

[0011] Therefore, by setting two floating ball switches at different heights in this application, multi-level monitoring and early warning of the water level are realized, which can more accurately reflect the change of the water level and provide more timely and accurate information support for disaster prevention and reduction work. Compared with a single water level monitoring method, the two-point water level alarm device can more accurately judge the rising speed and trend of the water level, so as to issue an early warning signal in advance and gain more time to cope with natural disasters such as floods.

[0012] Preferably, the alarm system includes:

[0013] An alarm module, connected to the control module, for emitting a first alarm signal and a second alarm signal respectively when receiving the first control signal and the second control signal;

[0014] A short message notification module, connected to the control module, for sending a first short message notification and a second short message notification respectively when receiving the first control signal and the second control signal.

[0015] With the above technical features, when the control module issues the first control signal, it indicates that the water level has reached the first threshold. At this time, the alarm module receives the first control signal and issues the first alarm signal for alarm. At the same time, the SMS notification module sends the first SMS notification to the preset mobile phone number to inform the relevant personnel that the water level has reached the first threshold; when the control module issues the second control signal, it indicates that the water level has reached the second threshold. At this time, the alarm module receives the second control signal and issues the second alarm signal for alarm. At the same time, the SMS notification module sends the second SMS notification to the preset mobile phone number to inform the relevant personnel that the water level has reached the second threshold. The alarm module can immediately issue an alarm signal when the water level reaches the warning line, reminding the on-site personnel to pay attention, which helps to quickly respond and take measures to prevent the expansion of the disaster; the SMS notification module can send the water level information to the relevant remote personnel or management department in real time, so that they can obtain important information in a timely manner no matter where they are, so as to make decisions and scheduling faster. By combining the two methods of on-site alarm and remote notification, the alarm system can significantly improve the efficiency of emergency response, ensure that the emergency plan can be quickly activated in case of disaster, and reduce the disaster losses.

[0016] Preferably, the alarm module includes a first controller, a second controller, and an alarm component. The input end of the first controller is connected to the output end of the control module. The output end of the first controller is respectively connected to the input ends of the second controller and the alarm component. The output end of the second controller is connected to the input end of the alarm component;

[0017] The first controller is used to issue a third control signal when receiving the first control signal. The second controller is used to issue a fourth control signal when receiving the third control signal. The alarm component is used to issue a first alarm signal when receiving the fourth control signal;

[0018] The first controller is used to issue a fifth control signal when receiving the second control signal. The alarm component is used to issue a second alarm signal when receiving the fifth control signal.

[0019] Through the above technical features, when the control module detects that the water level reaches the first threshold and issues the first control signal, the signal is transmitted to the input end of the first controller. After receiving the first control signal, the first controller performs preliminary processing and issues the third control signal. The third control signal is sent to the input end of the second controller. After receiving the third control signal, the second controller issues the fourth control signal. When the alarm component receives the fourth control signal, it issues the first alarm signal to immediately remind the relevant personnel on site; when the water level continues to rise and triggers the second float switch, and the control module issues the second control signal, the signal is transmitted to the input end of the first controller. The first controller directly issues the fifth control signal to the alarm component. When the alarm component receives the fifth control signal, it issues the second alarm signal to immediately remind the relevant personnel on site. Through the coordinated work of the first controller and the second controller, more complex alarm logic and signal processing can be achieved, enabling the alarm signal to be flexibly customized according to actual needs, such as adjusting the volume, frequency of the alarm sound or the flashing mode of the optical signal, etc. Moreover, the two-stage control structure can shorten the time interval from receiving the control signal to issuing the alarm signal, improving the emergency response speed. Especially in emergency situations, a faster alarm response can gain more time for personnel evacuation and disaster response.

[0020] Preferably, the first controller is configured to issue a sixth control signal when receiving the second control signal, the second controller is configured to issue a seventh control signal when receiving the sixth control signal, and the alarm component stops issuing the first alarm signal when receiving the seventh control signal.

[0021] Through the above technical features, when the water level continues to rise and triggers the second float switch, the control module will issue the second control signal. After receiving the second control signal, the first controller issues the sixth control signal. After receiving the sixth control signal, the second controller issues the seventh control signal. After receiving the seventh control signal, the alarm component will immediately stop issuing the first alarm signal. By stopping the first alarm signal when the water level reaches a higher threshold, false alarms or redundant alarms generated when the low water level alert has been lifted but the high water level alert has not been triggered can be avoided, helping to reduce unnecessary panic and chaos and improving the efficiency of emergency response.

[0022] Preferably, the alarm component includes a sound alarm and an alarm light, and the input ends of the sound alarm and the alarm light are both connected in parallel to the output ends of the first controller and the second controller.

[0023] With the above technical features, after the sound alarm receives the control signal, it will issue a corresponding sound alarm according to the instructions of the signal. Similarly, after the alarm light receives the control signal, it will light up or flash according to the instructions of the signal to give an alarm in the form of optical signals. By using the sound alarm and the alarm light simultaneously, it can ensure that the alarm signal can be clearly perceived in various environments. The sound signal can cover a wider area, while the optical signal can provide an effective alarm prompt in noisy or line-of-sight restricted environments.

[0024] Preferably, the horn of the sound alarm is a high-pitched horn, the sounding distance of the sound alarm is L, 150m ≤ L ≤ 300m, and the alarm light is a red light alarm.

[0025] With the above technical features, the long-distance sounding ability of the high-pitched horn (150m ≤ L ≤ 300m) ensures that the sound alarm signal can be clearly heard within a large range. The red optical signal of the red light alarm also has good long-distance visibility and can attract people's attention at a relatively long distance.

[0026] Preferably, the control module includes a time-delay relay.

[0027] With the above technical features, when the water level rises to the first threshold and the second threshold, the time-delay relay will be triggered. The time-delay relay outputs the first control signal and the second control signal, and stops signal output after reaching the preset time.

[0028] Preferably, the power supply module includes a solar panel and a solar battery controller. The solar panel is connected to the input end of the solar battery controller, and the output end of the solar battery controller is respectively connected to the input ends of the control module, the first float switch, and the second float switch.

[0029] With the above technical features, the solar panel collects solar energy and converts it into electrical energy, and then the solar charge and discharge controller conducts charge and discharge management to provide stable electrical energy for the entire device. There is no need for an external power supply, which is both energy-saving and environmentally friendly, convenient and practical, and can ensure the stable power supply of the alarm device under bad weather conditions, improving the reliability of the alarm system.

[0030] In summary, the present application has the following beneficial effects:

[0031] (1) By setting two float switches at different heights, the present application realizes multi-level monitoring and early warning of the water level, can more accurately reflect the change of the water level, and provides more timely and accurate information support for disaster prevention and mitigation work. Compared with a single water level monitoring method, the two-point water level alarm device can more accurately judge the rising speed and trend of the water level, so as to issue an early warning signal in advance and gain more time to cope with natural disasters such as floods.

[0032] (2) The alarm module of this application can immediately send an alarm signal when the water level reaches the warning line, alerting the on-site personnel and helping to quickly respond and take measures to prevent the expansion of disasters; the SMS notification module can send the water level information to relevant remote personnel or management departments in real time, enabling them to obtain important information in a timely manner regardless of their location, thus making decisions and dispatching more quickly. By combining on-site alarms and remote notifications, the alarm system can significantly improve the efficiency of emergency response, ensure the rapid activation of emergency plans in the event of disasters, and reduce disaster losses.

[0033] (3) By stopping the first alarm signal when the water level reaches a higher threshold in this application, false alarms or redundant alarms generated when the low water level warning has been lifted but the high water level warning has not been triggered can be avoided, which helps to reduce unnecessary panic and chaos and improve the efficiency of emergency response.

Detailed Embodiment

[0037] The following are specific embodiments of this application in combination with the drawings to further describe the technical solutions of this application, but this application is not limited to these embodiments.

[0038] As Figure 1 、 Figure 2 shown, this application discloses a two-point water level alarm device, including: the first float switch 1, the second float switch 2, the control module 3, the alarm system 4, and the power supply module 5.

[0039] The first float switch 1 is used to output a first float detection signal (ready to transfer) when the water level reaches the first threshold; the second float switch 2 is used to output a second float detection signal (immediately transfer) when the water level reaches the second threshold, and the second threshold is greater than the first threshold.

[0040] The control module includes a time-delay relay. The output ends of the first float switch 1 and the second float switch 2 are connected in parallel with the input end of the time-delay relay. When the water level reaches the threshold for ready transfer, the time-delay relay receives the first float detection signal, the time-delay relay is triggered, and the time-delay relay sends out a first control signal. In this application, the time set for each trigger of the extension relay is two minutes; when the water level reaches the threshold for immediate transfer, the time-delay relay receives the second float detection signal, the time-delay relay is triggered for two minutes, and the time-delay relay sends out a second control signal.

[0041] The alarm system 4 includes an alarm module 42 and a short message notification module 41. The input ends of the alarm module 42 and the short message notification module 41 are connected in parallel to the output end of the control module 3, and both can receive the first control signal and the second control signal of the control module 3. When the control module 3 sends out the first control signal, it indicates that the water level has reached the first threshold (ready to transfer). At this time, the alarm module 42 receives the first control signal and sends out a first alarm signal. At the same time, the short message notification module 41 sends a first short message notification to the preset mobile phone number to inform the relevant personnel that the water level has reached the first threshold; when the control module 3 sends out the second control signal (immediate transfer), it indicates that the water level has reached the second threshold. At this time, the alarm module 42 receives the second control signal and sends out a second alarm signal. At the same time, the short message notification module 41 sends a second short message notification to the preset mobile phone number to inform the relevant personnel that the water level has reached the second threshold.

[0042] The alarm module 42 includes a first controller 421, a second controller 422, and an alarm component 423. The input end of the first controller 421 is connected to the output end of the control module 3. The output end of the first controller 421 is respectively connected to the input ends of the second controller 422 and the alarm component 423. The output end of the second controller 422 is connected to the input end of the alarm component 423.

[0043] When the control module 3 detects that the water level reaches the first threshold and sends out the first control signal, this signal is transmitted to the input end of the first controller 421. After receiving the first control signal, the first controller 421 performs preliminary processing and sends out a third control signal. The third control signal is sent to the input end of the second controller 422. After receiving the third control signal, the second controller 422 sends out a fourth control signal. When the alarm component 423 receives the fourth control signal, it sends out a first alarm signal to immediately remind the relevant personnel on site; when the water level continues to rise and triggers the second float switch 2, and the control module 3 sends out the second control signal, this signal is transmitted to the input end of the first controller 421. The first controller 421 directly sends out a fifth control signal to the alarm component 423. When the alarm component 423 receives the fifth control signal, it sends out a second alarm signal to immediately remind the relevant personnel on site.

[0044] Upon receiving the second control signal, the first controller 421 issues a sixth control signal. Upon receiving the sixth control signal, the second controller 422 issues a seventh control signal. Upon receiving the seventh control signal, the alarm component 423 ceases issuing the first alarm signal. By suspending the first alarm signal when the water level reaches a higher threshold, false alarms or redundant alerts can be avoided when the low water level alert has been released but the high water level alert has not yet been triggered. This helps reduce unnecessary panic and confusion and improves the efficiency of emergency response.

[0045] In this application, the alarm component 423 includes an audible alarm 4231 and an alarm light 4232. The input ends of the audible alarm 4231 and the alarm light 4232 are both connected in parallel to the output ends of the first controller 421 and the second controller 422. The speaker of the audible alarm 4231 is a tweeter. The activation distance of the audible alarm 4231 is L, 150m≤L≤300m. The alarm light 4232 is a red light alarm light 4232, which can ensure that the alarm signal can be clearly perceived in various environments. The sound signal can cover a wider area, while the light signal can provide an effective alarm prompt in noisy or limited-viewing environments.

[0046] The power supply module 5 includes a solar panel 51 and a solar cell controller 52. The solar panel 51 is connected to the input end of the solar cell controller 52, and the output end of the solar cell controller 52 is respectively connected to the input ends of the control module 3, the first float switch 1 and the second float switch 2. Charging and discharging management is performed through the solar charge and discharge controller to provide stable power for the entire device without the need for an external power supply. It is energy-saving, environmentally friendly, convenient and practical, and can ensure stable power supply to the alarm device under severe weather conditions, thereby improving the reliability of the alarm system 4.

[0047] Working principle: When the water level rises to the first threshold, the first float switch 1 outputs the first float detection signal. When the delay relay receives the first float detection signal, it triggers the issuance of the first control signal. When the SMS notification module 41 receives the first control signal, it sends a first SMS notification to the preset mobile phone number, informing relevant personnel that the water level has reached the first threshold and notifying relevant personnel to prepare for transfer. When the first controller 421 of the alarm module 42 receives the first control signal, it outputs the third control signal. After receiving the third control signal, the second controller 422 outputs the fourth control signal. When the sound alarm 4231 and the alarm light 4232 receive the fourth control signal, they emit a sound signal: the first alarm signal of preparation for transfer and a corresponding light signal. The sound signal and light signal alarm last for two minutes.

[0048] When the water level rises to the second threshold, the second float switch 2 outputs a second float detection signal, and the delay relay triggers and issues a second control signal when receiving the second float detection signal. The SMS notification module 41 sends a second SMS notification to a preset mobile phone number when receiving the second control signal, informing relevant personnel that the water level has reached the second threshold and notifying them to transfer immediately; the second controller 422 of the alarm module 42 outputs a fifth control signal when receiving the second control signal, and the sound alarm 4231 and the warning light 4232 emit a sound signal: the second alarm signal of "transfer immediately" and the corresponding optical signal, and the alarm of the sound signal and the optical signal lasts for two minutes. At the same time, the first controller 421 is used to issue a sixth control signal when receiving the second control signal, and the second controller 422 issues a seventh control signal when receiving the sixth control signal, and the sound alarm 4231 and the warning light 4232 stop emitting the first alarm signal when receiving the seventh control signal.

[0049] The specific embodiments described herein are merely illustrative of the present application. Those skilled in the art to which the present application pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the scope defined by the present application.
