[0033] The present disclosure is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] In order to solve the technical problems of high manual detection cost and operational safety risks in the prior art, the present disclosure provides a road waterlogging early warning method, system and related devices based on power line transmission.

[0035] Figure 1 The flowchart of the road flooding warning method based on power line transmission provided by the present disclosure is shown as follows: Figure 1 As shown, the road waterlogging early warning method based on power line transmission includes the following steps:

[0036] S101, acquiring an ultrasonic signal, where the ultrasonic signal is an ultrasonic signal reflected from a flooded road surface.

[0037] In this step, an ultrasonic signal is acquired, where the ultrasonic signal is an ultrasonic signal reflected from a flooded road surface.

[0038] Specifically, water level monitoring sensors are installed on sections of urban roads that are prone to flooding; preferably, the sensors are non-contact sensors. At the same time, considering that the water level on urban roads usually does not exceed 3 meters, ultrasonic sensors can be selected, for example; such selection is conducive to improving measurement accuracy and reducing costs.

[0039] S102: Determine water depth information of the flooded road surface based on the ultrasonic signal.

[0040] After completing the above step S101, in this step, the water depth information of the flooded road surface is determined based on the ultrasonic signal.

[0041] Further, Figure 2 The flowchart of the steps of determining the water depth information of a flooded road surface based on ultrasonic signals provided by the present disclosure is shown as follows: Figure 2 As shown, the method of determining the water depth information of the flooded road surface based on the ultrasonic signal includes the following steps:

[0042] S201, determining the operation time of the ultrasonic wave based on the ultrasonic wave signal.

[0043] In this step, the operation time of the ultrasonic wave is determined based on the ultrasonic wave signal.

[0044] Specifically, after the transmitting end of the ultrasonic sensor emits an ultrasonic wave, the ultrasonic wave is transmitted toward the water surface, and is reflected on the water surface and then transmitted back. The receiving end of the ultrasonic sensor receives the transmitted ultrasonic wave. At this time, the running time of the ultrasonic wave is calculated based on the time when the transmitting end of the ultrasonic sensor emits the ultrasonic wave and the time when the receiving end receives the transmitted ultrasonic wave. That is, the time when the receiving end receives the transmitted ultrasonic wave minus the time when the transmitting end of the ultrasonic sensor emits the ultrasonic wave is the running time of the ultrasonic wave.

[0045] S202: Calculate water depth information of the flooded road surface based on the ultrasonic operation time.

[0046] After completing the above step S201, in this step, the water depth information of the flooded road surface is calculated based on the ultrasonic running time.

[0047] Specifically, Figure 3 The schematic diagram of the ultrasonic sensor distance measurement provided by the present disclosure is shown in FIG. As shown in the figure, the ultrasonic running time t is proportional to the distance S, S = (C*t) / 2, where C represents the speed of sound. After determining the time from the emission to the reception of the ultrasonic wave, the distance between the sensor and the water surface can be calculated according to the above formula, and then the distance S is subtracted from the distance L between the ultrasonic sensor and the ground to obtain the real water depth information W.

[0048] S103, transmitting the water depth information to a cloud server via a power line.

[0049] After completing the above step S102, in this step, the water depth information is transmitted to the cloud server via the power line.

[0050] Further, Figure 4 The flowchart of the steps of transmitting the water depth information to the cloud server via the power line provided by the present disclosure is shown as follows: Figure 4 As shown, the transmitting of the water depth information to the cloud server via the power line comprises the following steps:

[0051] S301, transmitting the water depth information to the concentrator based on the power line carrier technology.

[0052] In this step, the water depth information is transmitted to the concentrator based on the power line carrier technology.

[0053] Specifically, after determining the water depth information, the signal transmitting component transmits the water depth information to the substation meter reading concentrator through power line carrier communication, and uses the existing power lines to transmit signals through carrier communication. There is no need to specially arrange transmission lines or set up wireless communication equipment. Signal transmission can be achieved using existing power lines, without increasing costs, which is also conducive to the layout of equipment.

[0054] S302, the concentrator transmits the water depth information to a cloud server based on wireless transmission technology.

[0055] After completing the above step S301, in this step, the concentrator transmits the water depth information to the cloud server based on wireless transmission technology.

[0056] Specifically, the area meter reading concentrator can collect water depth information at various locations in the area, and use the existing wireless communication network of the area meter reading concentrator to transmit the water depth information to the cloud server. The area meter reading concentrator itself needs to transmit the power consumption data of the area through the wireless communication network. Using the area meter reading concentrator to transmit water depth information can further broaden the data transmission range and help reduce equipment costs.

[0057] S104: The cloud server determines road surface water warning information based on the water depth information.

[0058] After completing the above step S103, in this step, the cloud server determines the road surface water warning information based on the water depth information.

[0059] Further, Figure 5 The flowchart of the steps of determining the road surface flooding warning information based on the water depth information provided by the cloud server of the present disclosure is shown as follows: Figure 5 As shown, the cloud server determines the road surface water warning information based on the water depth information, including the following steps:

[0060] S401, comparing the water depth information with a first threshold, and generating first warning information when the water depth information is greater than or equal to the first threshold.

[0061] In this step, the water depth information is compared with a first threshold value, and when the water depth information is greater than or equal to the first threshold value, a first warning information is generated; wherein, the first warning information is used to prompt danger information to pedestrians and vehicles to prohibit pedestrians and vehicles from passing, and the first threshold value is set according to road administration requirements.

[0062] S402, comparing the water depth information with a second threshold, and generating second warning information when the water depth information is less than the first threshold and greater than or equal to the second threshold; wherein the first threshold is greater than the second threshold.

[0063] In this step, the water depth information is compared with the second threshold value. When the water depth information is less than the first threshold value and greater than or equal to the second threshold value, a second warning information is generated; wherein, the first threshold value is greater than the second threshold value, and the second warning information is used to alert pedestrians and vehicles to pass with caution.

[0064] S105, generating prompt information and operator deployment instructions based on the warning information.

[0065] After completing the above step S104, in this step, prompt information and operator deployment instructions are generated based on the warning information.

[0066] Specifically, after the cloud server determines the road surface waterlogging warning information based on the water depth information, it generates prompt information based on the level of the warning information, wherein the prompt information can be given through sound and light, or through voice broadcast, information prompt light, etc., to remind pedestrians and vehicles to pay attention to the water depth. At the same time, based on the warning information, an operator deployment instruction is generated to instruct the surrounding operators and operating vehicles to go to the waterlogged location in time to deal with the waterlogging.
