Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In this embodiment, a control system of a jet fan based on 5G is provided, and please refer to fig. 1 specifically, where the control system of the jet fan based on 5G includes a control server, a control node, and a jet fan. For example, a tunnel, a parking lot, or an application scenario corresponds to one control server, each control server is correspondingly connected to one or more control nodes, and each control node is correspondingly connected to one or more jet fans, for example, the jet fans may be disposed at various positions in the tunnel. In this embodiment, the jet fan is connected with the control node, and the control node is connected with the control server, that is to say, the jet fan does not need to be directly connected with the control server, that is to say, the jet fan only needs to be connected with the control node that is set up in the tunnel equally. In a specific embodiment, the connection between the jet fan and the control node may be through a 5G network connection, the jet fan corresponds to the UE terminal, the control node corresponds to the base station, and the jet fan and the control node are connected through the 5G network connection and perform data communication. Then, the control node is connected with the control server through a wire or other modes to carry out communication between the control node and the control server.

Specifically, referring to fig. 2, the jet fan includes an environmental sensor and a first communication module.

The environment sensor is arranged outside the jet flow fan and used for collecting environment parameters around the jet flow fan, and the environment parameters comprise wind power detection data, temperature detection data and noise detection data. Wherein, can set up one or more environmental sensor on the efflux fan, can include temperature sensor, sound sensor, wind sensor etc. can detect the environmental parameter that corresponds in the environment that the efflux fan is located, can detect the environmental parameter that efflux fan itself and surrounding environment correspond to can make follow-up can be based on the effectual efflux fan of controlling of the environmental parameter that detects.

Further, after the environmental parameters are detected by the environmental sensor, the acquired environmental parameters may be further sent to the control node, so that the control node performs subsequent further processing. Specifically, the first communication module is used for sending the environmental parameters acquired by the sensor to a control node connected with the jet flow fan through the first communication module, wherein the communication module at least comprises a 5G communication unit. That is to say, the jet fan is connected with the second communication module in the control node through the first communication module, so that data communication, for example, transmission of data and instructions, can be performed between the jet fan and the control node.

It should be noted that, in order to ensure the communication quality of the internet of things corresponding to the jet fan, the jet fan includes not only the 5G communication unit but also other communication units, such as a 4G communication unit or a WIFI communication unit. And preferentially adopts the 5G communication unit to carry out communication, and switches to other communication unit to carry out communication when the 5G communication is not smooth. Specifically, the first communication module is further configured to detect a 5G connection state corresponding to the 5G communication unit, and determine whether to switch to another communication unit for communication according to the 5G connection state; wherein the 5G connection state comprises one or more of signal strength, signal bandwidth and channel idle rate. If the 5G connection state cannot meet the preset condition, it indicates that there is a certain unsmooth communication through the 5G network under the current condition, and in order to ensure the communication quality, it is necessary to switch to another communication unit for communication, so as to ensure the stability and communication quality of communication, and improve the accuracy of the control of the jet fan.

Further, referring to fig. 2, the control node includes a second communication module and a second processing module, where: the second communication module is connected with the first communication module of the jet fan and used for receiving data sent by the jet fan; and the second processing module is used for packaging the environment parameters of each connected jet fan and then sending the packaged environment parameters to the control server through the second communication module.

And the control node is communicated with the jet flow fan through a second communication module and is also communicated with the control server through second communication. The second communication module is used for receiving data uploaded by the jet fan, and the data are uploaded to the control server through the second communication module.

Furthermore, the control node also processes the environment parameters uploaded by each connected jet flow fan through a second processing module, and then uploads the processed data to the control server, so that the control server controls the jet flow fans according to the environment parameters. That is, the data corresponding to the environmental parameter acquired by the jet flow fan is not directly uploaded to the control server, but the data needs to be processed, for example, encryption processing, data feature extraction processing, or the like, and is not limited herein.

Further, referring to fig. 2, the control server includes a third communication module and a third processing module. The control server is connected with the second communication module through the third communication module to realize data communication between the control server and the control node, so that the control server can receive data (such as environmental parameters) sent by the control node, and the control node can receive data or instructions sent by the control server.

The control server processes the received environment parameters through the third processing module and calculates the environment parameters to determine control parameters of each jet flow fan, wherein the control parameters are used for controlling the jet flow fans, so that the jet flow fans can work according to the control parameters to achieve corresponding control effects.

Further, the control server calculates a target control parameter corresponding to each jet flow fan based on a preset control parameter calculation model according to the received environment parameter of each jet flow fan and the position information of the jet flow fan prestored in the control server, and according to the environment parameter corresponding to the current environment where each jet flow fan is located and the position parameter corresponding to each jet flow fan. Wherein the control parameters comprise one or more of air volume, wind pressure, noise, frequency, power and wind direction. That is, the air volume, air pressure, noise, frequency, power, wind direction, etc. of the jet fan can be controlled by the target control parameters.

Further, the control server is further configured to forward the target control parameter to the jet fan via the control node (not directly sent to the jet fan by the control server), so that the jet fan is controlled to operate according to the received target control parameter.

In a specific embodiment, how to calculate the target control parameter for each jet fan is further described.

Firstly, when calculating the target control parameter, not only the environmental parameter detected by the environmental sensor but also the position information corresponding to each jet flow fan need to be considered, because the position of the jet flow fan directly affects the control of the jet flow fan, for example, the control of the jet flow fan in the middle of the tunnel is different from the control of the jet flow fan at the exit of the tunnel, and the influence of the environment and the influence of other jet flow fans are also different. The position information of the jet flow fan comprises an environment map set by the jet flow fan, such as a tunnel map, and the height, direction, influence area and the like set by each jet flow fan, so that the target control parameters of the jet flow fan can be calculated more accurately.

In specific implementation, the environmental parameters of each jet flow fan need to be determined, and the position information of each jet flow fan needs to be determined; and then, calculating a target control parameter corresponding to each jet flow fan according to the environmental parameter and the position information of each jet flow fan and a preset air channel control effect parameter and a preset control parameter calculation model. It should be noted that, because each of the jet flow fans are mutually influenced and not independent, when calculating the target control parameter of each of the jet flow fans, all the jet flow fans need to be considered comprehensively, that is, the environmental parameters and the corresponding position information of the plurality of jet flow fans are taken as a set as a whole, and the target control parameter of each of the jet flow fans is calculated according to the parameter corresponding to the control effect of the air duct that needs to be achieved as a whole.

In a specific embodiment, the preset control parameter calculation model may be a neural network model, which may better handle the calculation of multiple inputs and multiple outputs. Specifically, the control parameter calculation model includes a plurality of submodels, and a first model and a second model connected to each submodel, where each jet fan corresponds to one submodel, and the submodels, the first model, and the second model may be neural network models.

Specifically calculating, namely respectively inputting the environment parameter corresponding to each jet flow fan into the sub-model corresponding to each jet flow fan so as to obtain the environment characteristic of each jet flow fan; then, performing characteristic splicing on the environmental characteristics output by each sub-model and the position information corresponding to the jet flow fan, inputting the environmental characteristics and the position information into a first model, and outputting a master control parameter through the first model; the spliced position information may be feature position information after feature extraction has been performed. Since the position information of each jet fan is set in advance, the feature extraction of the position information may be position information after feature extraction has been performed in advance according to a preset position feature extraction model to obtain corresponding feature position information. Further, the total control parameters and the position information corresponding to each jet flow fan need to be input into the second model, and the target control parameters corresponding to each jet flow fan are determined. That is to say, first, feature extraction is performed on the relevant data of each jet flow fan, and then the data are respectively input into the first model to be calculated based on a desired air duct control effect (preset air duct control effect parameter) so as to obtain a total control parameter for controlling the plurality of jet flow fans. And then further splitting the total control parameter based on the environmental parameter and the position information of each jet flow fan, namely inputting the environmental characteristic and the characteristic position information corresponding to each jet flow fan and the total control parameter into a second model, and then calculating the target control parameter corresponding to each jet flow fan through the second model, thereby completing the calculation of the control parameter of the jet flow fan.

On the other hand, in order to fully utilize the advantages of the 5G network, data communication of the internet of things of the jet fan is performed through the 5G network, and in order to further improve the stability of the data, the data needs to be encrypted and the like to prevent tampering and improve the stability and accuracy of the data.

The first step is as follows: and the jet flow fan processes the environment parameters according to a preset hash function to obtain a first hash value. Here, the first hash value may characterize the environmental parameter, and the first hash value is also used for subsequent data verification. Then, the environment parameter and the first hash value are combined, for example, data splicing processing, data addition processing, or convolution processing is performed to obtain the first environment data after combination, and then the first environment data is sent to the connected control node. That is to say, the jet fan does not directly send the acquired environmental parameters to the control node, but sends the corresponding first environmental data obtained after processing the environmental parameters to the control node for further processing.

The second step is that: the control node stores preset keys corresponding to each jet flow fan, wherein after receiving first environment data corresponding to one jet flow fan, the control node needs to obtain the corresponding keys, then encrypts the first environment data corresponding to the current jet flow fan based on the keys, and generates encrypted second environment data.

Then, merging the encrypted second environment data and the merged first environment data to obtain merged third environment data; the third environment data can be further sent to the control server for subsequent processing.

Further, in this embodiment, the position information of each jet fan may be stored in the control node, and therefore, here, the position information of the jet fan may be further combined with the first environmental data and the second environmental data to obtain a third environmental treatment.

In another embodiment, in order to further improve the stability of the data, when the control node uploads the data to the control server, the control node uploads the third environment data to the block link point corresponding to the control node, and stores the third environment data in a storage region corresponding to each jet fan under the block link point; each control node corresponds to one block chain node, and each block chain node comprises a storage area corresponding to one or more jet flow fans connected with the control node. And then, the control server acquires the environment data corresponding to each jet fan by accessing the block chain nodes. That is, for each jet fan in the storage area under the block link point, the corresponding control node and the corresponding control server respectively have data uploading (i.e. editing) authority and data reading authority. The corresponding authority may be to dispense drops at the time of setting up the jet blower and then to verify the authority at each data processing.

The third step: and the control server is connected with the block chain nodes, acquires third environment data corresponding to each jet fan from the block chain nodes, and analyzes and processes the third environment data to obtain the environment parameters corresponding to each jet fan.

In this embodiment, the control server needs to perform the anti-hash process and the decryption process corresponding to the hash process and the encryption process for the analysis process of the third environment data. Specifically, the third environmental data is subjected to inverse combination processing to obtain the first environmental data, the second environmental data and the position information of the jet fan. And then, based on the key corresponding to each jet flow fan stored in the control server, carrying out decryption processing on the second environment data. The key corresponding to each jet fan is generated by the control server and issued to the control node, so that the key corresponding to each jet fan is stored in the control server, and when decrypting, the corresponding key is obtained and decrypted, and the decrypted data is obtained. Here, the second environment data is decrypted, because the second environment data is obtained by encrypting the first environment data, it is necessary to compare the data obtained by decrypting the second environment data with the first environment data to determine whether the corresponding data is tampered. And if the comparison result is consistent, continuing to perform inverse combination processing on the first environment data, performing inverse hash processing, comparing the environment parameters after the inverse hash processing with the environment parameters obtained by the inverse combination processing of the first environment processing, and if the comparison result is consistent, acquiring the environment parameters corresponding to the jet flow fan.

And if any one of the comparison results is inconsistent, discarding corresponding data, and controlling the jet flow fan corresponding to the current data communication of the terminal so as to wait for the next acquisition of the environmental parameters, data transmission and the like of the jet flow fan and perform the next control of the jet flow fan.

That is to say, in this embodiment, through 5G network, data encryption processing and block chain technology, multiple guarantee is provided to the data transmission of the thing networking of efflux fan to guarantee the reliability of data, improved the accuracy of efflux fan control, and guaranteed the low time delay of data based on 5G network, improved the real-time of efflux fan control.

Because the jet fan is used for continuously collecting the environmental parameters of the surrounding environment, the environmental parameters are generally changed slightly in a short time, and if a large amount of sensor data needs to be transmitted every time, the burden of network transmission is not caused. Thus, in this embodiment, the slowly varying nature of the environmental parameter may be utilized, and after each sensor data acquisition, the incremental data (also referred to as modified data) between the last acquired sensor data may be further calculated. That is to say, after the jet flow fan acquires the environmental parameters through the environmental sensor, modified data between the currently acquired environmental parameters and the environmental parameters acquired last time is determined as the environmental parameters for subsequent processing; therefore, the data transmission quantity of each time is reduced, the burden of data transmission is reduced, and the possibility of data transmission blockage and packet loss is further reduced.

In another embodiment, the data size of the incremental data transmitted each time may be further considered, and the data size transmitted each time may be large or small, and the corresponding data transmission and communication modes may be given according to the data size. Specifically, according to the data volume of the incremental data, the network (for example, whether the network is a 5G network) currently performing communication, the data protocol format, the channel for data transmission, and the like are determined, and then the data is encapsulated, transmitted, received, and parsed based on the determined parameters of the communication.

Because a communication network, a data protocol format, a data transmission channel, and the like can be selected, in this embodiment, the control node packages the merged first environment data, the encrypted second environment data, and the position information of each jet fan according to a corresponding preset package format, where in a package after the package, the data length of the merged first environment data, the encrypted second environment data, and the position information of each jet fan corresponds to the preset data protocol format; that is to say, the content and format corresponding to each piece of data are defined in the data protocol format, and in this embodiment, corresponding data encapsulation needs to be performed according to the size of the data volume, so as to ensure the stability of the data in the transmission process. Further, a target communication channel can be determined based on a preset data protocol format; and uploading the data packet obtained by encapsulation to the blockchain node for storage based on the determined target communication channel. Or determining a communication channel corresponding to each communication according to the communication conditions of all the current radio frequency fans and the communication nodes of all the control nodes, and then transmitting data based on the determined communication signals so as to further guarantee the stability of data transmission and improve the stability of the Internet of things of the jet flow fan.

After the control system of the jet fan based on the 5G is adopted, the jet fan is in communication connection with the control node through the 5G communication unit, and the control node is in communication connection with the control server, so that the jet fan detects environmental parameters around the jet fan through the environmental sensor and then sends the environmental parameters to the control node through the 5G network, the control node further packages the data related to the environmental parameters and then sends the data to the control server, the control server analyzes the received packaged data to obtain the environmental parameters of the jet fan, the target control parameters of each jet fan are calculated by combining the position information of the jet fan, and the target control parameters are forwarded to the jet fan through the control node, so that the control of the jet fan based on the calculated target control parameters is realized. The target control parameters of each jet flow fan are calculated in a linkage manner based on the surrounding environment and in combination with the position information of the jet flow fans, so that the control accuracy of the jet flow fans can be improved; moreover, an Internet of things system of the jet flow fan is constructed through a 5G network, so that the stability and low time delay of data transmission of the jet flow fan under the Internet of things can be improved, and the accuracy and real-time performance of control of the jet flow fan are improved; in addition, the jet fan does not need to be directly in communication connection with the control server, but is in communication through the control node which is also arranged in the tunnel, so that the requirements on the communication environment of the jet fan in the closed environment such as the tunnel can be reduced, the packet loss rate of data communication is reduced, and the control precision of the jet fan is improved.
