[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In addition, the technical features in the various embodiments or single embodiments provided by the present invention can be arbitrarily combined with each other to form a feasible technical solution. This combination is not subject to the constraints of the sequence of steps and / or the structural composition mode, but must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0017] Figure 1 A block diagram of an Internet-based intelligent control system provided by the present invention is shown in FIG. Figure 1 As shown, the intelligent control system includes multiple data collectors and an intelligent central controller, each data collector is connected to one or more front-end sensors through an adapter interface, the intelligent central controller and all data collectors in the local area network are connected in series using a network cable, and the cable is looped back to the intelligent central controller to form an Ethernet-based ring network structure, each data collector in the ring network structure is connected to the intelligent central controller via the Internet, and the intelligent central controller is connected to the remote platform via the network.

[0018] Each of the data collectors is used to collect sensor data collected by one or more front-end sensors connected thereto, and upload the data to the intelligent central controller; The intelligent central controller is used to analyze and process the sensor data uploaded by all data collectors, and report the analysis and processing results to the remote platform; and forward the instruction message sent by the remote platform to the front-end sensor through the data collector.

[0019] It is understandable that if Figure 1 As shown, the Internet-based intelligent control system includes an intelligent central controller and multiple data collectors, wherein the front-end sensors at multiple measuring points that are relatively close can share one data collector, and one data collector is used to upload the sensor data collected by these multiple front-end sensors to the intelligent central controller.

[0020] Among them, the front-end sensors include rain monitoring stations, termite activity monitoring stations, seepage flow / seepage pressure monitoring stations and surface deformation monitoring stations arranged at various measuring points.

[0021] Each data logger can be connected to multiple front-end sensors at the same time, and the data logger can adapt to different types of interfaces and interfaces of various sensors. For example, the adapter interface of the data logger can support RS485, RS232, DI and DO protocols.

[0022] The intelligent central controller is deployed in the smart central station and is connected in series with all data collectors in the local area network using a network cable, which is finally looped back to the intelligent central controller to form an Ethernet-based ring network structure. Each data collector in the ring network structure is connected to the intelligent central controller through a network cable. Therefore, the failure of any data collector in the ring network structure will not affect the normal operation of other data collectors.

[0023] Among them, the intelligent center controller is mainly responsible for uploading sensor data and issuing instructions. Similar to the existence of gateway devices, it is necessary to repackage and distribute sensor data and instructions to adapt to different types of equipment. At the same time, it is also necessary to analyze and process the sensor data uploaded by the front-end sensors and automatically diagnose faults, which is equivalent to having front-end edge computing capabilities. The intelligent center controller is connected to the remote platform and the data collector based on the Internet.

[0024] The data collector is the hub of the front-end sensor and the intelligent central controller. It is responsible for collecting data from each front-end sensor and reporting it to the intelligent central controller for analysis and processing. It also receives and analyzes instructions from the intelligent central controller or the platform forwarded by the intelligent central controller to the front-end sensor, and finally outputs them to the specific front-end sensor for execution. It is connected to the intelligent central controller through the Internet, and connected to the front-end sensor through RS485, RS232, DI, DO and other interfaces that are suitable for various sensors.

[0025] Figure 2 The present invention provides an intelligent control method for an Internet-based intelligent control system, comprising: Step 1: Each data collector collects sensor data collected by one or more front-end sensors connected to it and uploads it to the intelligent central controller.

[0026] Exemplarily, each data collector collects sensor data collected by one or more front-end sensors connected thereto, and uploads the data to the intelligent central controller, including: A priority is set for the sensor data collected by each front-end sensor; when congestion occurs during the process of the data collector uploading sensor data to the intelligent central controller, the data collector uploads the sensor data collected by all the front-end sensors to the intelligent central controller in order of priority based on the priority of the sensor data collected by the front-end sensors.

[0027] It is understandable that due to the densely populated areas of some front-end sensors, the amount of data from the front-end sensors is relatively large. Therefore, the amount of sensor data collected by the front-end sensors will be relatively large. Uploading all the sensor data collected by the front-end sensors to the intelligent central controller at one time will cause network congestion, so it is necessary to upload in batches.

[0028] One of the ways is to set a priority for the sensor data collected by each front-end sensor. When congestion occurs during the process of uploading sensor data to the intelligent central controller, all sensor data can be uploaded to the intelligent central controller through the data collector in priority order according to the priority of the sensor data.

[0029] Exemplarily, each of the data collectors collects sensor data collected by one or more front-end sensors connected to it, and uploads it to the intelligent central controller, including: setting a priority for the sensor data collected by each front-end sensor; in the process of the data collector uploading sensor data to the intelligent central controller, if the size of the sensor data uploaded by the data collector to the intelligent central controller exceeds the set size, the sensor data is segmented, and the segmented sensor data is uploaded to the intelligent central controller in order of priority.

[0030] Another solution to network congestion is: when the sensor data uploaded by each data collector to the intelligent central controller is greater than the set data volume, the sensor data can be segmented and uploaded to the intelligent central controller in order of priority to achieve batch transmission.

[0031] Step 2: The intelligent central controller analyzes and processes the sensor data uploaded by all data collectors, and reports the analysis and processing results to the remote platform.

[0032] It is understandable that when the front-end sensor uploads the sensor data to the intelligent central controller, the intelligent central controller analyzes and processes the sensor data to analyze whether the measuring point where the sensor is located has a fault. After analyzing and processing the sensor data, the intelligent central controller reports the analysis and processing results to the remote platform.

[0033] Exemplarily, the intelligent central controller analyzes and processes the sensor data uploaded by all data collectors, and reports the analysis and processing results to the remote platform, including: the intelligent central controller analyzes and processes the sensor data uploaded by all data collectors, packages the analysis and processing results, compresses the packaged data packets, and reports them to the remote platform; after receiving the compressed data packets, the remote platform decompresses the compressed data packets to obtain the original analysis and processing results.

[0034] It is understandable that, since the amount of data of the analysis and processing results of the sensor data by the intelligent central controller is relatively large, the intelligent central controller can first package the analysis and processing results, and then compress the packaged data packets, and upload the compressed data packets to the remote platform. When the remote platform receives the compressed data packets, it compresses the compressed data packets to obtain the original analysis and processing results.

[0035] Step 3: forward the command message sent by the remote platform to the front-end sensor through the data collector.

[0036] Exemplarily, the method of forwarding the command message sent by the remote platform to the front-end sensor through the data collector includes: when the remote platform needs to send a command message to the front-end sensor, the remote platform sends the command message to the intelligent central controller, and the command message carries the identifier of the front-end sensor to be sent; the intelligent central controller finds the data collector corresponding to the front-end sensor according to the identifier of the front-end sensor to be sent carried in the command message, and sends the command message to the data collector; according to the identifier of the front-end sensor to be sent carried in the command message, the data collector sends the command message to the corresponding front-end sensor.

[0037] It is understandable that the remote platform can also send instructions to the front-end sensor, and the process of sending instructions includes: the remote platform sends an instruction message to the intelligent center controller, and the instruction message carries the identifier of the front-end sensor to which the instruction is to be sent. After receiving the instruction message, the intelligent center controller sends the instruction message to the corresponding data collector according to the identifier of the front-end sensor carried therein, and then the data collector sends the instruction message to the corresponding front-end sensor.

[0038] The embodiment of the present invention provides an Internet-based intelligent control system and control method, which adopts the method of locally building a local area network, and realizes that all front-end sensors are unique in the local area network through the combination of an intelligent central controller and a plurality of data collectors, and all data and instructions are collected, analyzed, processed and forwarded in the intelligent central controller. The intelligent central controller and the remote platform only need one network cable and one IP to realize the reporting of all measurement point data in the area and remote control of each front-end sensor separately, so as to achieve the purpose of saving costs and network resources.
