Detailed ways

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 , the present invention designs a wave elimination system based on the Internet of Things, including several regional wave elimination networks 4 , a cloud platform 2 and a server 1 . The regional wave elimination network accesses the network through the signal base station 3 , and communicates with the cloud platform 2 and the server 1 through the signal base station 3 .

The several regional wave elimination networks 4, wherein each wave elimination network includes several wave elimination equipment such as A, B, C and an equipment control device; the wave elimination equipment is arranged on the water surface and establishes communication with the equipment control device connection; the equipment control device, as shown in FIG. 2 , includes a power supply module, a sensor module, an abnormality detection module, a main control module, a communication module, and a dispatch control module, wherein the power supply module is used to supply power to the device; the control module, It is used to output the first control signal to drive each wave elimination equipment to move to the water surface position, and to control the water level and wave height data collected by the sensor module and the operation data of the wave elimination equipment detected by the abnormal detection module to be uploaded to the server and the cloud platform through the communication module, The dispatching control instruction sent by the server is received through the communication module, and a second control signal is generated accordingly and output through the dispatching control module to drive the corresponding wave elimination equipment to run.

The server 1 is used to receive and display the water level and wave height data collected by each wave elimination network and the detected operation data of the wave elimination equipment, and judge whether the wave elimination equipment is abnormal according to the operation data of the wave elimination equipment. It is used for early warning; and it is used to receive the dispatching plan of wave elimination equipment sent by the cloud platform and generate dispatch control instructions to the corresponding wave elimination network accordingly.

The cloud platform 2 is used to pre-establish an evaluation index of wave elimination equipment wave elimination ability composed of wave height data, wave elimination coefficient, wave elimination performance coefficient of wave elimination knot equipment, and wave resistance ability of bank protection, and to eliminate wave elimination equipment. The wave capacity evaluation index is combined with the dispatching cost to obtain the wave elimination equipment dispatch plan; and it is used to count the maximum wave height data according to the received water level and wave height data collected by each wave elimination network, and calculate the wave elimination coefficient. The wave elimination performance of the equipment is mapped to the evaluation index of the wave elimination ability of the wave elimination equipment, and the required wave elimination equipment scheduling scheme is selected from the wave elimination equipment scheduling scheme in combination with the dispatch cost, and the wave elimination equipment dispatch scheme is sent to the server.

Specifically, the cloud platform calculates the maximum wave height data according to the uploaded wave height data, and then according to the revetment capability, that is, the acceptable maximum wave height, calculates the required minimum wave elimination coefficient through the following formula:

Among them, K is the wave extinction coefficient, the unit is %; h ₀ is the incident wave height before the wave is eliminated by the wave-proof forest, the unit is m; h is the wave height after the wave is eliminated by the wave-proof forest, the unit is m. The larger the wave absorption coefficient, the greater the attenuation of the waves by the vegetation, that is, the better the wave elimination effect of the wave prevention forest; on the contrary, the smaller the wave absorption coefficient, the smaller the attenuation degree of the vegetation to the wave, and the worse the wave elimination effect of the wave prevention forest. .

Then, according to the wave-dissipating performance of each wave-dissipating structure and the dispatching cost, several feasible dispatching schemes are obtained. For example, the wave elimination equipment using wave elimination structure is A, B, C, its wave elimination capacity α is 20%, 40%, 60%, the operating cost β is 50,100,200 yuan, and the minimum wave elimination coefficient α0 is ₃₀ %, at this time, scheduling scheme 1: B can be used; scheduling scheme 2: C; and then according to the preferred formula Y = β/α, Y1 is 250, Y2 is 333.33, so scheme 1 is selected as the final scheduling scheme output and transmitted to server.

Therefore, according to the received real-time upload data, the cloud platform optimizes the scheduling scheme of the wave elimination equipment in combination with the wave elimination capability evaluation index of each wave elimination equipment and the wave resistance capability of the bank protection. Realize remote control and automatic management of wave elimination equipment; in addition, the server control terminal is also responsible for real-time monitoring of the operation status of each wave elimination equipment and the remaining power of the power supply system, and timely maintenance according to early warning to ensure normal operation.

According to the wave elimination coefficient obtained by the wave height difference before and after wave elimination of a single wave elimination equipment compared with the initial incident wave, the wave elimination ability evaluation index is constructed, and then combined with economic cost, maintenance cost, terrain conditions and other factors, a variety of wave elimination equipment are selected according to local conditions. Combine waves.

After the AC transformer detects it, the main control chip sends an alarm signal to the server control end, and the control relay disconnects the power supply line and uploads abnormal data to the server through the communication module. And when scheduling is required, the communication module receives the scheduling control instruction sent by the server, and generates a second control signal based on this, and outputs the second control signal to the connected wave-eliminating equipment through the scheduling module to output control to drive the corresponding wave-eliminating equipment to run.

The communication module includes a local area network communication module, a wide area network communication module and an RS485 interface module, all of which are electrically connected with the main control chip. The local area network communication module is to wirelessly form a local area network with each wave elimination device in the regional wave elimination network; the wide area network communication module is to form a local area network with wireless communication between the local area network and the signal base station to connect to the Internet and communicate with the server control terminal. The LAN communication module adopts 433 wireless module or ZigBee module; the WAN communication module adopts GPRS module, 4G module or NB-IOT module.

The power supply module supplies power to each module by the solar power supply system, and is electrically connected to the main control module. When the remaining power of the power supply device is detected to be lower than the built-in threshold, the main control chip sends an alarm signal to the server control terminal, and alarms as the power decreases. The level of the signal will be enhanced, and the threshold value should ensure sufficient time for the replenishment of the battery to ensure the normal operation and communication requirements of the wave elimination network in the IoT area.

The device may also include a button control module and an indicator light for manual control to perform operations such as opening, closing, and resetting, and the indicator light is used to display the working status and power status of the wave elimination equipment; When the ambient temperature is too high, the main control module sends an alarm signal to the server control terminal; the storage module caches the data received and processed by the main control module through the memory chip, including storage water level and wave height data and wave elimination equipment operation data.

The broadcast control mode is realized by the concentrator. By operating the concentrator in a certain area, you can send instructions to all the devices in the area. The two methods respectively realize large-area unified control and single-point precise control, with strong flexibility. In this way, the dispatching control instruction of the wave elimination equipment scheduling scheme is generated to the corresponding wave elimination network.

The server receives and displays the water level and wave height data collected by each wave elimination network and the detected operation data of the wave elimination equipment, and judges whether the wave elimination equipment is abnormal according to the operation data of the wave elimination equipment, and gives an early warning when it is judged that there is an abnormality; Parameter setting is used to set the overvoltage, voltage loss, and overcurrent parameters of three-phase power, as a reference for sending out alarm information. It is also used to query and obtain the historical record report data of the wave elimination equipment in each wave elimination network, and select the wave elimination equipment according to the frequency of use and upload it to the cloud platform. Query data of usage report, built-in and external energy report, energy meter history report and controller energy meter record report. Upload its data to the cloud platform. Based on big data analysis, the cloud platform obtains the most frequently used and least frequently used wave elimination equipment in each area, and allocates equipment between regions to avoid inventory retention or vacancy, and make full use of each wave elimination equipment. To ensure the continuous operation of the wave elimination system. For example, according to the alarm rate and usage rate of wave elimination equipment A, B, and C, the survival of the fittest can be achieved. If the alarm rate of area A is small and the usage rate is small, then the wave elimination equipment A in area A is extracted and controlled for wave elimination; if the alarm rate of area B is small and the utilization rate is high, then the wave elimination equipment in area B is Equipment B is not selected, and other equipment with low utilization rate such as A or C is considered; the excess B in area A can be given to B area, and the excess A in B area can be given to A area.

The cloud platform stores the water level and wave height data, and responds to the dispatch plan generation request. If the wave height data does not exceed the wave resistance capacity of the bank protection, it will not start; if it exceeds, the difference between the measured wave height and the wave resistance capacity is used to compare the measured wave height. , calculate the required minimum wave elimination coefficient, and then combine the wave elimination capability evaluation index of each wave elimination equipment to select the optimal cost-effective wave elimination equipment combination scheduling scheme that meets the revetment requirements. The cloud platform returns the scheduling result to the server control terminal, and the decision maker agrees or fine-tunes the result and then returns the result to the scheduling control module to drive the wave elimination equipment to run.
