Example two

Fig. 6 is a flowchart of a road water monitoring method provided by the second embodiment of the present invention. The method can be applied to the road accumulated water monitoring terminal provided by any embodiment of the invention, and has the corresponding method flow and beneficial effects of the monitoring terminal. The method can be executed by the road ponding monitoring device provided by the embodiment of the invention, and the device can be realized by hardware and/or software and can be integrated in a monitoring terminal. As shown in fig. 6, the method specifically includes the following steps:

s61, receiving first measurement data collected by the water level measurement module, and determining a first water level risk factor according to the first measurement data.

Specifically, in the process of using the monitoring terminal to monitor the accumulated water, the water level measuring module can be used for measurement by conventional default, namely, only the water level measuring module is used for collecting data, and the collected first measurement data is trusted. When the first measurement data appears unstable and jumps, if the water level suddenly and rapidly changes, or the water level measurement module collects errors and other conditions, the pressure sensor can be used for measurement at the same time, so that the water level is measured in a double-backup mode, and the stability, effectiveness and reliability of the final water level data are ensured. The first water level risk factor may be determined in real time from the first measurement data during the measurement using the water level measurement module, so as to determine whether the measurement using the pressure sensor is currently required, i.e. the first water level risk factor may be used to measure the current stability of the first measurement data.

Optionally, the determining a first water level risk factor according to the first measurement data includes: determining first real-time water level data and a first unit time water level change value according to the first measurement data; and determining the first water level risk factor according to the first real-time water level data and the first unit time water level change value. Specifically, the first real-time water level data, that is, the current latest water level data, may be determined according to the latest received first measurement data, and the current first water level change value per unit time may also be determined according to a certain amount of latest historical first measurement data (which may include the latest data), and then the first real-time water level data and/or the first water level change value per unit time may be directly used as the first water level risk factor. The larger the first real-time water level data is, the more serious the current water accumulation condition is, the water level change is usually faster, meanwhile, the user pays more attention to the current water level data, and at the moment, a pressure sensor can be added for measurement to ensure accuracy. The larger the water level change value in the first unit time is, the sudden and abrupt change of the water level is possible, or errors may occur in the acquisition of the water level measurement module, and at the moment, a pressure sensor can be added for measurement so as to ensure accuracy.

S62, judging whether power needs to be supplied to the pressure sensor according to the first water level danger factor, if so, supplying power to the pressure sensor, receiving second measurement data acquired by the pressure sensor, and determining a second water level danger factor according to the second measurement data.

Specifically, after the first water level risk factor is determined, as described above, it may be determined whether a pressure sensor needs to be added for measurement according to the first water level risk factor, for example, the first real-time water level data may be compared with a preset water level threshold, the water level change value in the first unit time may be compared with a preset water level change value, and the comparison result is then integrated for determination. If the pressure sensor is required, the micro control unit can control the power management module to supply power to the pressure sensor so as to enable the pressure sensor to work, and therefore second measurement data collected by the pressure sensor can be received. Similarly, then, a second water level risk factor may be determined in real time from the second measurement data, which may be used to measure the current stability of the second measurement data for subsequent adjustment of the acquisition frequency and reporting frequency.

Optionally, the determining a second water level risk factor according to the second measurement data includes: determining second real-time water level data and a second unit time water level change value according to the second measurement data; and determining the second water level danger factor according to the second real-time water level data and the second unit time water level change value. Specifically, the second real-time water level data, that is, the current latest water level data, may be determined according to the latest received second measurement data, and the current second water level change value per unit time may also be determined according to a certain amount of latest historical second measurement data (which may include the latest data), and then the second real-time water level data and/or the second water level change value per unit time may be directly used as the second water level risk factor. The larger the first real-time water level data and the second real-time water level data are, the more serious the current water accumulation condition is, the water level change is usually faster, meanwhile, the user pays more attention to the current water level data, and the acquisition frequency and the reporting frequency can be adjusted to meet the user requirements. The larger the water level change value in the first unit time and the water level change value in the second unit time are, the water level may suddenly and rapidly change, at this time, the requirement of the user on the water level data is dense, and the acquisition frequency and the reporting frequency can be adjusted to meet the requirement of the user.

S63, determining water level data according to the first measurement data and the second measurement data, and reporting the water level data to an external terminal through a wireless transmission module.

Specifically, after the first measurement data and the second measurement data are obtained, the water level data may be determined according to the first measurement data and the second measurement data, for example, the current latest first measurement data and the current latest second measurement data may be directly used as the water level data, two water level values may be calculated according to a certain number of latest historical first measurement data (which may include the latest) and a certain number of latest historical second measurement data (which may include the latest) as the water level data, one of the current latest measurement data or the water level value may be selected as the water level data, and the like. After the water level data is determined, the current water level data can be reported to an external terminal through a wireless transmission module in real time so as to be conveniently checked by a user.

Optionally, the determining water level data according to the first measurement data and the second measurement data includes: determining the weights of the first measurement data and the second measurement data according to the first water level change value per unit time and the second water level change value per unit time; and filtering the first measurement data and the second measurement data according to the weight to obtain the water level data. Specifically, the final water level data can be determined by referring to the stability of the measurement data acquired by the water level measurement module and the pressure sensor, and if the first measurement data acquired by the water level measurement module jumps and the second measurement data acquired by the pressure sensor is relatively stable, the second measurement data can be given a larger weight, and the first measurement data can be given a smaller weight, that is, the second measurement data is more trusted. Then, the two measurement data can be integrated, and filtering processing is carried out according to respective weights, so as to obtain final water level data. The filtering method may include a median filtering method, an arithmetic mean filtering method, a median mean filtering method, a weighted mean filtering method, and the like, wherein the median mean filtering method may be preferably adopted, that is, a specified number of historical measurement data are sorted, the maximum value and the minimum value are removed, and the average value of the remaining measurement data is calculated as the final value, so that error data which occasionally occur can be effectively rejected.

And S64, determining a comprehensive water level danger factor according to the first water level danger factor and the second water level danger factor, and adjusting the acquisition frequency and the reporting frequency according to the comprehensive water level danger factor.

Specifically, as described above, the integrated water level risk factor may include at least one of the first real-time water level data, the first unit time water level variation value, the second real-time water level data, and the second unit time water level variation value, so as to determine the current water level condition or water level variation condition, and adjust the collection frequency and the reporting frequency in real time according to the user requirement.

Optionally, the adjusting the collection frequency and the reporting frequency according to the comprehensive water level risk factor includes: respectively comparing the first real-time water level data and the second real-time water level data with a first preset dynamic threshold value, and respectively comparing the first unit time water level change value and the second unit time water level change value with a second preset dynamic threshold value; if the first real-time water level data or the second real-time water level data is greater than the first preset dynamic threshold value, or if the first unit time water level variation value or the second unit time water level variation value is greater than the second preset dynamic threshold value, the acquisition frequency and the reporting frequency are increased. Specifically, the comprehensive water level risk factor may include first real-time water level data, a first water level change value per unit time, second real-time water level data, and a second water level change value per unit time, and first, for the water level measurement module, if the first real-time water level data is greater than or equal to a first preset dynamic threshold, the collection frequency and the report frequency may be increased to a first level, if the first real-time water level data is less than the first preset dynamic threshold and the first water level change value per unit time is greater than or equal to a second preset dynamic threshold, the collection frequency and the report frequency may be increased to a second level, otherwise, the collection frequency and the report frequency may be kept unchanged. Then, aiming at the pressure sensor, if the second real-time water level data is greater than or equal to a first preset dynamic threshold value, the acquisition frequency and the reporting frequency can be increased to a first level, if the second real-time water level data is less than the first preset dynamic threshold value and the water level change value in the second unit time is greater than or equal to a second preset dynamic threshold value, the acquisition frequency and the reporting frequency can be increased to a second level, otherwise, the acquisition frequency and the reporting frequency can be kept unchanged.
