Description

Technical Field

[0001] The present invention relates to the field of geological disaster deformation monitoring, and particularly to a method and system for controlling the working mode of a Beidou terminal based on rainfall. Background Technique

[0002] The Beidou high-precision positioning terminal is a machine widely used in the deformation monitoring of geological disasters, usually installed at potential landslide hazard points. At these hazard points, most terminals cannot be powered by mains electricity, so basically they are powered by solar energy. The power supply method of solar energy is relatively simple, but its power supply effect completely depends on the weather. Once there is a long period of rainy weather, the Beidou terminal is very likely to have a power feed situation. Therefore, in order to save power, the Beidou terminal needs to have the functions of automatic sleep and wake-up, so as to reserve sufficient power to cope with rainy weather. However, although the automatic sleep and wake-up mechanism of the Beidou terminal can save the power of the solar battery, it cannot output high-precision positioning data information in real time during the sleep period. This is because the Beidou terminal cannot perform high-precision positioning calculation in the sleep state, and thus cannot output relevant data.

[0003] Under the background of the prior art, in thunderstorm weather, the Beidou terminal needs to obtain high-precision positioning data information in real time, so as to quickly and timely grasp the actual deformation situation of the current hazard point to be monitored. Therefore, there is a contradiction between the power saving of the Beidou terminal during sleep and the real-time output of high-precision positioning data information. Summary of the Invention

[0004] The present invention aims to provide a method and system for controlling the working mode of a Beidou terminal based on rainfall, so as to solve the above technical problems, avoid the problem that high-precision positioning data information cannot be output in real time due to power saving during sleep, and ensure that the Beidou terminal can control the sleep working mode of the terminal according to the current rainfall, and balance the contradiction between power saving during sleep and real-time output of high-precision positioning data information.

[0005] To solve the above technical problems, the present invention provides a method for controlling the working mode of a Beidou terminal based on rainfall, including the following steps:

[0006] Respond to the real-time obtained rainfall data, calculate and judge the current rainfall situation in the environment, determine the rainfall trend based on the rainfall data, and then obtain the rain-time sleep wake-up duration ratio of the Beidou terminal according to the rainfall trend;

[0007] Generate a rain-time sleep wake-up duration ratio signal command based on the rain-time sleep wake-up duration ratio, and send the rain-time sleep wake-up duration ratio signal command to the whole machine power supply to control the whole machine power supply to supply power to the Beidou terminal at a fixed time, so as to realize the automatic switching of the working mode of the Beidou terminal between the sleep state and the working state.

[0008] In the above solution, the rainfall trend is determined by the real-time obtained rainfall data, and the rain-time sleep wake-up duration ratio of the Beidou terminal is obtained according to the magnitude of the rainfall trend. On the premise of ensuring the monitoring effect of the Beidou terminal, the energy utilization can be optimized, and at the same time, early warning measures can be taken in a timely manner to provide guarantee. A rain-time sleep wake-up duration ratio signal instruction is generated according to the rain-time sleep wake-up duration ratio and sent to the whole machine power supply. Furthermore, the Beidou terminal can switch between the sleep state and the working state according to the real-time rainfall data, balancing the contradiction between power saving during sleep and real-time output of high-precision positioning data information.

[0009] Furthermore, it also includes:

[0010] If it does not rain, the normal sleep wake-up duration ratio of the Beidou terminal is obtained;

[0011] The normal sleep wake-up duration ratio is 8:2;

[0012] Based on the normal sleep wake-up duration ratio, a normal sleep wake-up duration ratio signal instruction is generated, and the normal sleep wake-up duration ratio signal instruction is sent to the whole machine power supply to control the whole machine power supply to supply power to the Beidou terminal at regular intervals, realizing the automatic switching of the working mode of the Beidou terminal between the sleep state and the working state.

[0013] In the above solution, through generating and sending the normal sleep wake-up duration ratio signal instruction, the automatic control of the Beidou terminal is realized. When it does not rain, the Beidou terminal can sleep longer and work shorter, and the normal sleep wake-up duration ratio is 8:2. The Beidou terminal can automatically enter the sleep state or the working state according to the preset duration ratio, and can accurately control the sleep and working time of the Beidou terminal. In the sleep state, the power supply can reduce the power supply to the Beidou terminal, reducing energy consumption; in the working state, sufficient power is provided to the Beidou terminal in a timely manner to ensure its normal operation, and it can continuously collect and transmit data of the monitoring point.

[0014] Furthermore, in response to the real-time obtained rainfall data, calculate and judge the rainfall situation in the current environment, and determine the rainfall trend based on the rainfall data. Furthermore, obtain the rain-time sleep wake-up duration ratio of the Beidou terminal according to the rainfall trend, specifically:

[0015] In response to the real-time obtained rainfall data, calculate the daily accumulated rainfall data, and determine the rainfall trend based on the daily accumulated rainfall data: when the daily accumulated rainfall data is less than 10 mm, the rainfall trend is light rain; when the daily accumulated rainfall data is 10 - 25 mm, the rainfall trend is moderate rain; when the daily accumulated rainfall data is greater than 25 mm, the rainfall trend is heavy rain;

[0016] Obtain the rain-time sleep wake-up duration ratio of the Beidou terminal according to the rain intensity: when the rain intensity is light rain, the rain-time sleep wake-up duration ratio is 6:4; when the rain intensity is moderate rain, the rain-time sleep wake-up duration ratio is 4:6; when the rain intensity is heavy rain, the rain-time sleep wake-up duration ratio is 2:8.

[0017] In the above solution, a quantization standard for rain intensity is defined. By dividing the daily accumulated rainfall data into different intervals to define light rain, moderate rain, and heavy rain, it provides a clear and objective basis for adjusting the working mode of the Beidou terminal according to different rain intensities, enabling the system to make differential responses according to different rainfall degrees. As the rain intensity increases, the sleep duration is gradually shortened and the working duration is extended, ensuring that when the possibility of geological disasters increases due to the increasing rain intensity, the Beidou terminal can perform real-time positioning at a high frequency and timely monitor the deformation of the point to be monitored.

[0018] Furthermore, it also includes:

[0019] Control the Beidou terminal to perform real-time positioning in the working state to obtain Beidou high-precision positioning data information, and upload the Beidou high-precision positioning data information to the early warning service platform.

[0020] In the above solution, when the Beidou terminal is awakened and enters the working state, control it to perform real-time positioning to obtain Beidou high-precision positioning data information. These data are the key basis for judging whether the monitoring point has deformed. Uploading the obtained Beidou high-precision positioning data information to the early warning service platform can enable the platform to analyze the data in a timely manner. Once it is found that there are abnormal deformations or other situations that may cause geological disasters at the monitoring point, an early warning can be quickly issued so that relevant personnel can take measures in a timely manner to ensure the safety of people's lives and property.

[0021] The present invention provides a system for controlling the working mode of a Beidou terminal based on rainfall, including a central control processing module, a sleep wake-up timing control module, a whole machine power control module, and a Beidou positioning module, where:

[0022] The central control processing module is used to respond to the real-time obtained rainfall data, calculate and judge the rainfall situation in the current environment, determine the rain intensity based on the rainfall data, and then obtain the rain-time sleep wake-up duration ratio of the Beidou positioning module according to the rain intensity;

[0023] The central control processing module is also used to generate a rain-time sleep wake-up duration ratio signal instruction based on the rain-time sleep wake-up duration ratio, and send the rain-time sleep wake-up duration ratio signal instruction to the sleep wake-up timing control module;

[0024] The sleep wake-up timing control module is used to receive the rain-time sleep wake-up duration ratio signal instruction, and based on the rain-time sleep wake-up duration ratio signal instruction, control the whole machine power control module to supply power to the Beidou positioning module at regular intervals, so as to realize the automatic switching of the working mode of the Beidou positioning module between the sleep state and the working state.

[0025] The system structure of the Beidou terminal machine based on rainfall data provided by the above solution is simple. In actual application, it only needs to accurately analyze the rainfall data obtained in real time through the central control processing module to judge the rainfall situation of the current environment, and provide a basis for obtaining the rain-time sleep wake-up duration ratio of the Beidou positioning module. Then, when it is raining, the central control processing module determines the rain intensity based on the rainfall data, and obtains the corresponding rain-time sleep wake-up duration ratio according to different rain intensities, ensuring that when the possibility of geological disasters increases, the Beidou positioning module can work more frequently and obtain monitoring data in a timely manner. After the central control processing module completes the decision-making of the working mode, it transmits the decision-making information to the sleep wake-up timing control module by sending a rain-time sleep wake-up duration ratio signal instruction, providing an indication for subsequent timed power supply and Beidou positioning module wake-up operations. Then the sleep wake-up timing control module receives the rain-time sleep wake-up duration ratio signal instruction and controls the whole machine power control module according to this signal instruction. By accurately controlling the whole machine power control module to supply power to the Beidou positioning module at regular intervals, the sleep duration and working duration of the Beidou positioning module are controlled, so that the Beidou positioning module works according to the preset rain-time sleep wake-up duration ratio, thus realizing the goal of energy saving while ensuring the monitoring effect of geological disasters.

[0026] Further, if it does not rain, the central control processing module is used to obtain the normal sleep wake-up duration ratio of the Beidou positioning module;

[0027] The normal sleep wake-up duration ratio is 8:2;

[0028] The central control processing module is further used to generate a normal sleep wake-up duration ratio signal instruction based on the normal sleep wake-up duration ratio, and send the normal sleep wake-up duration ratio signal instruction to the sleep wake-up timing control module;

[0029] The sleep wake-up timing control module is used to receive the normal sleep wake-up duration ratio signal instruction, and based on the normal sleep wake-up duration ratio signal instruction, control the whole machine power control module to supply power to the Beidou positioning module at regular intervals, so as to realize the automatic switching of the working mode of the Beidou positioning module between the sleep state and the working state.

[0030] In the above solution, the central control processing module realizes the automatic switching of the working mode of the Beidou positioning module by generating and sending a signal instruction for the ratio of normal sleep wake-up duration. When the central control processing module determines that it is not raining, the Beidou positioning module can sleep longer and work shorter, and the ratio of normal sleep wake-up duration is 8:2. The Beidou positioning module can automatically enter the sleep or wake-up state according to the obtained ratio of normal sleep wake-up duration, and can accurately control the sleep and working time of the Beidou positioning module. In the sleep state, the power supply can reduce the power supply to the Beidou positioning module and reduce energy consumption; in the working state, it can provide sufficient power to the Beidou positioning module in time to ensure its normal operation and continuously collect and transmit data at the monitoring point.

[0031] Furthermore, the central control processing module is configured to calculate and determine the current rain situation in response to the rainfall data obtained in real time, determine the rain intensity based on the rainfall data, and then obtain the ratio of rain-time sleep wake-up duration of the Beidou positioning module according to the rain intensity, where:

[0032] The central control processing module is configured to calculate the daily accumulated rainfall data in response to the rainfall data obtained in real time, and determine the rain intensity based on the daily accumulated rainfall data: when the daily accumulated rainfall data is less than 10 mm, the rain intensity is light rain; when the daily accumulated rainfall data is 10 - 25 mm, the rain intensity is moderate rain; when the daily accumulated rainfall data is greater than 25 mm, the rain intensity is heavy rain;

[0033] Obtain the ratio of rain-time sleep wake-up duration of the Beidou positioning module according to the rain intensity: when the rain intensity is light rain, the ratio of rain-time sleep wake-up duration is 6:4; when the rain intensity is moderate rain, the ratio of rain-time sleep wake-up duration is 4:6; when the rain intensity is heavy rain, the ratio of rain-time sleep wake-up duration is 2:8.

[0034] In the above solution, a quantization standard for rain intensity is defined. By dividing the daily accumulated rainfall data into different intervals to define light rain, moderate rain and heavy rain, it provides a clear and objective basis for adjusting the working mode of the Beidou positioning module according to different rain intensities, enabling the system to make different responses according to different rainfall degrees. Obtaining the corresponding ratio of rain-time sleep wake-up duration for different rain intensities is a specific implementation method to balance the contradiction between power saving during sleep and real-time output of high-precision positioning data information. As the rain intensity increases, the sleep duration is gradually shortened and the working duration is extended to ensure that when the possibility of geological disasters increases, the Beidou positioning module can upload high-precision positioning data at high frequency and monitor the deformation of the point to be monitored in time.

[0035] Furthermore, the Beidou positioning module is further configured to perform real-time positioning and output high-precision Beidou positioning data information to the central control processing module when in the working state.

[0036] In the above solution, the Beidou positioning module can perform real-time positioning, accurately present the position of the monitoring point, and output Beidou high-precision positioning data information to the central control and processing module, providing a strong basis for the early warning of geological disasters.

[0037] Furthermore, it also includes a rain sensor module and a 4G network module:

[0038] The rain sensor module is used to obtain rainfall data in real time;

[0039] The 4G network module is used to transmit the Beidou high-precision positioning data information processed by the central control and processing module to the early warning service platform.

[0040] In the above solution, the 4G network module is responsible for transmitting the Beidou high-precision positioning data processed by the central control and processing module to the early warning service platform, realizing the circulation of data from the monitoring terminal to the platform. This enables these scattered data to quickly converge to the early warning service platform, providing a basis for subsequent analysis and processing.

[0041] Furthermore, it also includes:

[0042] Before responding to the real-time obtained rainfall data, the central control and processing module, the sleep / wake-up timing control module, the whole machine power control module, the rain sensor module, and the 4G network module are initialized first.

[0043] In the above solution, the central control and processing module, the sleep / wake-up timing control module, the whole machine power control module, the rain sensor module, and the 4G network module are initialized first, which can make the parameters and configurations of each module return to the initial set state. At the same time, when each module is initialized, the system resources will be reasonably allocated to ensure that subsequent operations can be accurately executed according to the predetermined logic.

[0045] Figure 2 It is a system architecture diagram of a system for controlling the working mode of a Beidou terminal based on rainfall provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0047] This embodiment provides a method for controlling the working mode of a Beidou terminal based on rainfall. For the specific steps, please refer to Figure 1 , including:

[0048] Step S1: In response to the rainfall data obtained in real time, calculate and determine the current rainfall situation in the environment, determine the rainfall trend based on the rainfall data, and then obtain the rainfall-time sleep wake-up duration ratio of the Beidou terminal according to the rainfall trend;

[0049] Step S2: Generate a rainfall-time sleep wake-up duration ratio signal instruction based on the rainfall-time sleep wake-up duration ratio, and send the rainfall-time sleep wake-up duration ratio signal instruction to the whole machine power supply to control the whole machine power supply to supply power to the Beidou terminal at regular intervals, so as to realize the automatic switching of the working mode of the Beidou terminal between the sleep state and the working state.

[0050] In this embodiment, aiming at finding a balance between the energy saving of the Beidou terminal and the frequency of uploading high-precision data, a method is proposed to determine the rainfall trend based on the rainfall amount, and then control the ratio of the sleep duration to the working duration of the Beidou terminal, so as to achieve both energy saving and ensuring that high-precision positioning data can be uploaded to the early warning service platform in a timely manner at critical times, producing an early warning effect. First, the MPU determines the rainfall trend through the rainfall data obtained in real time, and obtains the rainfall-time sleep wake-up duration ratio of the Beidou terminal according to the magnitude of the rainfall trend, which can optimize energy utilization on the premise of ensuring the monitoring effect, and can also take early warning measures in a timely manner to provide guarantee. Generate a rainfall-time sleep wake-up duration ratio signal instruction through the rainfall-time sleep wake-up duration ratio and send it to the whole machine power supply, so as to realize that the Beidou terminal can switch between the sleep state and the working state according to the current rainfall data, and balance the contradiction between sleep power saving and real-time output of high-precision positioning data information. Through the above steps, it is possible to save battery energy storage when the possibility of a disaster is low, and have sufficient battery energy storage to ensure that the host works for a long time and uploads high-precision positioning data information to the early warning service platform at a high frequency when the possibility of a disaster is high.

[0051] Furthermore, it also includes:

[0052] If there is no rainfall, obtain the normal sleep wake-up duration ratio of the Beidou terminal;

[0053] The normal sleep wake-up duration ratio is 8:2;

[0054] Generate a normal sleep wake-up duration ratio signal instruction based on the normal sleep wake-up duration ratio, and send the normal sleep wake-up duration ratio signal instruction to the whole machine power supply to control the whole machine power supply to supply power to the Beidou terminal at regular intervals, so as to realize the automatic switching of the working mode of the Beidou terminal between the sleep state and the working state.

[0055] In this embodiment, by generating and sending a signal instruction of the conventional sleep wake-up duration ratio by the MPU, the automatic control of the Beidou terminal is realized. The Beidou terminal can automatically enter the sleep state or the working state according to the preset duration ratio, and can accurately control the sleep and working time of the Beidou terminal. When the MPU determines that it is not raining, such as on a sunny day or a cloudy day, the probability of deformation at the monitoring point in the geological disaster site is relatively small, and the frequency of uploading high-precision positioning data information by the Beidou terminal can be lower. Therefore, the sleep time of the Beidou terminal can be longer and the working time can be shorter. The conventional sleep wake-up duration ratio is 8:2. For example, within 10 minutes, the Beidou terminal sleeps for 8 minutes and works for 2 minutes. And the sleep wake-up cycle is not fixed, but can be changed according to actual needs. In the sleep state, the power supply can reduce the power supply to the Beidou terminal and reduce energy consumption; in the working state, it can provide sufficient power for the Beidou terminal in time to ensure its normal operation and be able to continuously collect and transmit data of the monitoring point.

[0056] Further, in response to the rainfall data obtained in real time, calculate and judge the current rainfall situation in the environment, and determine the rainfall intensity according to the rainfall data. Then, obtain the rain-time sleep wake-up duration ratio of the Beidou terminal according to the rainfall intensity, specifically:

[0057] In response to the rainfall data obtained in real time, calculate the daily accumulated rainfall data, and determine the rainfall intensity based on the daily accumulated rainfall data: when the daily accumulated rainfall data is less than 10 mm, the rainfall intensity is light rain; when the daily accumulated rainfall data is 10 - 25 mm, the rainfall intensity is moderate rain; when the daily accumulated rainfall data is greater than 25 mm, the rainfall intensity is heavy rain;

[0058] Obtain the rain-time sleep wake-up duration ratio of the Beidou terminal according to the rainfall intensity: when the rainfall intensity is light rain, the rain-time sleep wake-up duration ratio is 6:4; when the rainfall intensity is moderate rain, the rain-time sleep wake-up duration ratio is 4:6; when the rainfall intensity is heavy rain, the rain-time sleep wake-up duration ratio is 2:8.

[0059] In this embodiment, a quantitative standard for rainfall intensity is defined. When the weather is bad, such as when it is raining or even raining heavily, the probability of deformation occurring at the monitoring points in the geological disaster area is relatively high. At this time, the need for the Beidou terminal to upload high-precision positioning data information is more frequent, and it may even be necessary to upload positioning data information in real time every second to ensure that the deformation of the monitoring points can be detected in a timely manner. Therefore, at this time, the Beidou terminal needs to have a shorter sleep time and a longer working time, or even not sleep at all and keep working. The MPU defines light rain, moderate rain, and heavy rain by calculating the daily accumulated rainfall data and dividing it into different intervals, providing a clear and objective basis for adjusting the working mode of the Beidou terminal according to different rainfall intensities, enabling the system to make differential responses according to different rainfall levels. When the MPU determines that it is light rain, the sleep time of the Beidou terminal can be appropriately shortened, and the working time can be appropriately extended. The sleep-wake-up duration ratio during rain is 6:4. For example, within 10 minutes, the Beidou terminal sleeps for 6 minutes and works for 4 minutes. When the MPU determines that it is moderate rain, the sleep time of the Beidou terminal is further shortened, and the working time is further extended. The sleep-wake-up duration ratio during rain is 4:6. For example, within 10 minutes, the Beidou terminal sleeps for 4 minutes and works for 6 minutes. When the MPU determines that it is heavy rain, the sleep time of the Beidou terminal is ensured to be the shortest, and the working time is the longest. The sleep-wake-up duration ratio during rain is 2:8. For example, within 10 minutes, the Beidou terminal sleeps for 2 minutes and works for 8 minutes. And the sleep-wake-up cycle is not fixed but can be changed according to actual needs. As the rainfall intensity increases, the MPU gradually shortens the sleep duration and extends the working duration to ensure that when the likelihood of geological disasters increases due to the increase in rainfall intensity, the Beidou terminal can monitor the deformation of the monitoring points at a high frequency, and there is sufficient battery energy storage when the likelihood of disaster occurrence is high to ensure that the Beidou terminal works for a long time and uploads high-precision positioning data information to the early warning service platform at a high frequency.

[0060] Further, it also includes:

[0061] Control the Beidou terminal to perform real-time positioning when it is in the working state to obtain Beidou high-precision positioning data information, and upload the Beidou high-precision positioning data information to the early warning service platform.

[0062] In this embodiment, when the Beidou terminal is awakened and enters the working state, control it to perform real-time positioning to obtain high-precision positioning data information, which is the key basis for judging whether the monitoring point has deformed. Uploading the obtained high-precision positioning data information to the early warning service platform enables the platform to analyze the data in a timely manner. Once it is found that there are abnormal deformations or other situations that may trigger geological disasters at the monitoring point, an early warning can be quickly issued so that relevant personnel can take measures in a timely manner to ensure the safety of people's lives and property.

[0063] Please refer to Figure 2, this embodiment provides a system for controlling the working mode of a Beidou terminal based on rainfall, including a central control and processing module, a sleep and wake-up timing control module, a whole-machine power control module, and a Beidou positioning module, where:

[0064] The central control and processing module is configured to respond to the rainfall data obtained in real time, calculate and judge the current rainfall situation in the environment, determine the rainfall trend based on the rainfall data, and then obtain the rainfall-time sleep and wake-up duration ratio of the Beidou positioning module according to the rainfall trend;

[0065] The central control and processing module is further configured to generate a rainfall-time sleep and wake-up duration ratio signal instruction based on the rainfall-time sleep and wake-up duration ratio, and send the rainfall-time sleep and wake-up duration ratio signal instruction to the sleep and wake-up timing control module;

[0066] The sleep and wake-up timing control module is configured to receive the rainfall-time sleep and wake-up duration ratio signal instruction, and control the whole-machine power control module to supply power to the Beidou positioning module at a fixed time based on the rainfall-time sleep and wake-up duration ratio signal instruction, so as to realize the automatic switching of the working mode of the Beidou positioning module between the sleep state and the working state.

[0067] The system for controlling the working mode of the Beidou terminal based on rainfall data provided in this embodiment has a simple structure. In practical applications, only the central control and processing module needs to accurately analyze the rainfall data obtained in real time to judge the rainfall situation in the current environment, providing a basis for setting the rainfall-time sleep and wake-up duration ratio of the Beidou positioning module. The central control and processing module can control all other modules and receive the original data information of all other modules, parse, process and make decisions on each data information. When it rains, the central control and processing module defines the rainfall trend based on the rainfall data, and sets the corresponding rainfall-time sleep and wake-up duration ratio according to different rainfall trends, ensuring that when the possibility of geological disasters increases, the Beidou positioning module can work more frequently to obtain monitoring data in a timely manner. After the central control and processing module completes the decision-making of the working mode, it transmits the decision-making information to the sleep and wake-up timing control module by sending a rainfall-time sleep and wake-up duration ratio signal instruction, providing an indication for subsequent timed power supply and Beidou positioning module wake-up operations. Then the sleep and wake-up timing control module receives the decision of the central control and processing module, and controls the whole-machine power control module according to the rainfall-time sleep and wake-up duration ratio signal sent by the central control and processing module to achieve the sleep and wake-up duration required by the central control and processing module. By accurately controlling the whole-machine power control module to supply power to the Beidou positioning module at a fixed time according to the current sleep and wake-up duration ratio, the sleep duration and working duration of the Beidou positioning module are controlled, so that the Beidou positioning module works according to the preset rainfall-time sleep and wake-up duration ratio, thereby achieving the goal of energy conservation while ensuring the monitoring effect of geological disasters.

[0068] Further, if it does not rain, the central control processing module is used to obtain the normal sleep wake-up duration ratio of the Beidou positioning module;

[0069] The normal sleep wake-up duration ratio is 8:2;

[0070] The central control processing module is further used to generate a normal sleep wake-up duration ratio signal instruction based on the normal sleep wake-up duration ratio, and send the normal sleep wake-up duration ratio signal instruction to the sleep wake-up timing control module;

[0071] The sleep wake-up timing control module is used to receive the normal sleep wake-up duration ratio signal instruction, and control the whole machine power control module to supply power to the Beidou positioning module at regular intervals based on the normal sleep wake-up duration ratio signal instruction, so as to realize the automatic switching of the working mode of the Beidou positioning module between the sleep state and the working state.

[0072] In this embodiment, the central control processing module realizes the automatic switching of the working mode of the Beidou positioning module by generating and sending a normal sleep wake-up duration ratio signal instruction to the sleep wake-up timing control module. The Beidou positioning module can automatically enter the sleep state or the working state according to the preset duration ratio, and can accurately control the sleep and working time of the Beidou positioning module. When the central control processing module determines that it does not rain, the Beidou positioning module can sleep longer and work shorter. Specifically, the normal sleep wake-up duration ratio is set to 8:2. For example, within 10 minutes, the Beidou positioning module sleeps for 8 minutes and works for 2 minutes. And the sleep wake-up cycle is not fixed, but can be changed according to actual needs. In the sleep state, the power supply can reduce the power supply to the Beidou positioning module and reduce energy consumption; in the working state, sufficient power is provided to the Beidou positioning module in time to ensure its normal operation and continuously collect and transmit data of the monitoring point.

[0073] Further, the central control processing module is used to respond to the real-time obtained rainfall data, calculate and judge the current environmental rainfall situation, determine the rainfall intensity according to the rainfall data, and then obtain the rainfall-time sleep wake-up duration ratio of the Beidou positioning module according to the rainfall intensity, where:

[0074] The central control processing module is used to respond to the real-time obtained rainfall data, calculate the daily accumulated rainfall data, and determine the rainfall intensity based on the daily accumulated rainfall data: when the daily accumulated rainfall data is less than 10 mm, the rainfall intensity is light rain; when the daily accumulated rainfall data is 10 - 25 mm, the rainfall intensity is moderate rain; when the daily accumulated rainfall data is greater than 25 mm, the rainfall intensity is heavy rain;

[0075] Obtain the rain-time sleep wake-up duration ratio of the Beidou positioning module according to the rain intensity: when the rain intensity is light rain, the rain-time sleep wake-up duration ratio is 6:4; when the rain intensity is moderate rain, the rain-time sleep wake-up duration ratio is 4:6; when the rain intensity is heavy rain, the rain-time sleep wake-up duration ratio is 2:8.

[0076] In this embodiment, a quantization standard for rain intensity is defined. By dividing the daily accumulated rainfall data into different intervals to define light rain, moderate rain, and heavy rain, it provides a clear and objective basis for adjusting the working mode of the Beidou positioning module according to different rain intensities, enabling the system to make differential responses according to different rainfall degrees. Obtaining the corresponding rain-time sleep wake-up duration ratio for different rain intensities respectively is a specific implementation method to balance the contradiction between sleep power saving and real-time output of high-precision positioning data information. When the central control processing module determines that it is light rain, appropriately shorten the sleep time of the Beidou positioning module and appropriately extend the working time of the Beidou positioning module. The rain-time sleep wake-up duration ratio is 6:4. For example, within 10 minutes, the Beidou positioning module sleeps for 6 minutes and works for 4 minutes; when the central control processing module determines that it is moderate rain, further shorten the sleep time of the Beidou positioning module and further extend the working time of the Beidou positioning module. The rain-time sleep wake-up duration ratio is 4:6. For example, within 10 minutes, the Beidou positioning module sleeps for 4 minutes and works for 6 minutes; when the central control processing module determines that it is heavy rain, ensure that the sleep time of the Beidou positioning module is the shortest and the working time is the longest. The rain-time sleep wake-up duration ratio is 2:8. For example, within 10 minutes, the Beidou positioning module sleeps for 2 minutes and works for 8 minutes. And the sleep wake-up cycle is not fixed but can be changed according to actual needs. As the rain intensity increases, the central control processing module gradually shortens the sleep duration and extends the working duration to ensure that when the rain intensity increases and the possibility of geological disasters increases, the Beidou positioning module can monitor the deformation of the monitoring point at a high frequency, and there is enough battery energy storage when the possibility of disaster occurrence is high to ensure that the Beidou positioning module works for a long time and uploads high-precision positioning data information to the early warning service platform at a high frequency.

[0077] Furthermore, the Beidou positioning module is also used to perform real-time positioning in the working state and output Beidou high-precision positioning data information to the central control processing module.

[0078] In this embodiment, the Beidou positioning module can perform real-time positioning and accurately present the position of the monitoring point. When the central control processing module detects a large rain intensity, it can obtain accurate Beidou high-precision positioning data and output Beidou high-precision positioning data information to the central control processing module. These data are the direct basis for judging whether the monitoring point has deformed and the degree of deformation, providing a strong basis for the early warning of geological disasters.

[0079] Furthermore, it also includes a rain gauge sensor module and a 4G network module:

[0080] The rain sensor module is used to obtain rainfall data in real time;

[0081] The 4G network module is used to transmit the Beidou high-precision positioning data information processed by the central control processing module to the early warning service platform.

[0082] In this embodiment, the rain sensor module detects the rainfall data of the current environment in real time and transmits the rainfall data to the central control processing module. The 4G network module is responsible for transmitting the Beidou high-precision positioning data processed by the central control processing module to the early warning service platform, realizing the circulation of data from the monitoring terminal to the platform, so that the platform can quickly and accurately prepare for the possible disaster warning of the monitoring point and make timely processing.

[0083] Furthermore, it further includes:

[0084] Before responding to the rainfall data obtained in real time, the central control processing module, the sleep / wake-up timing control module, the whole machine power control module, the rain sensor module and the 4G network module are first initialized.

[0085] In this embodiment, the central control processing module, the sleep / wake-up timing control module, the whole machine power control module, the rain sensor module and the 4G network module are first initialized, which can make the parameters and configurations of each module return to the initial set state. At the same time, when each module is initialized, the system resources will be reasonably allocated to ensure that the subsequent operations can be accurately executed according to the predetermined logic.

[0086] The above is the preferred implementation mode of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
