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.
The invention provides a power information sharing method based on the Internet of things. Referring to fig. 1, the power information sharing method includes steps S11 to S17.
S11, acquiring owner user information, wherein the owner user information comprises at least one electric power device bound with an owner user.
Specifically, the owner user is a user bound with at least one house identifier, and each house identifier is associated with at least one electric power device. For example, the power device may be a smart meter installed in a house, and may collect power consumption data and implement a control function, such as limiting power consumption, powering off, and the like, by receiving a control instruction of a user. The owner user binds with all the power equipment associated with the house identification by binding the house identification; the owner user information records all the electric power equipment bound with the owner user.
And S12, initiating power information sharing to a target user according to at least one power device in the owner user information.
Specifically, the power information sharing further includes a charging contract, and a payment reminder is sent to the target user according to the charging contract and a plaintext data set of the power device.
For example, the system publishes the information of the power equipment to the internet of things big data platform through the mqtt technology and the internet of things. And the house renting information is issued to the Internet of things big data platform by the owner through the equipment information. The tenants search the houses through the Internet of things platform, and place orders, sign contracts, pay for refuge house rents, pay for water and electricity charges and various miscellaneous charges are carried out. The big data platform of the Internet of things manages information of tenants in a unified mode, and the tenants can check electricity utilization conditions in real time after obtaining authorization. The user carries out the full transaction process of intelligent renting rooms through the platform, and information is completely shared. The Internet of things big data platform monitors the electricity utilization safety of the house through equipment, and feeds back the electricity utilization safety to users and tenants through socket pushing in time. Through the automatically generated equipment information sharing group, the equipment is shared, and a user obtains the control right of the house renting breaker. Sharing the conditions of real-time house renting and electricity utilization.
And S13, acquiring a data uploading request of the electric power equipment, and judging whether the electric power equipment meets a preset communication condition.
When any one of the electric power devices needs to upload information to the server, the data upload request is firstly sent to the server, so that the judgment of the communication condition by the server is triggered, and whether the asymmetric key updating steps of the steps S22 to S23 need to be executed or not is determined according to the judgment result.
Specifically, step S13 may include step S13-1 to step S13-2.
S13-1, acquiring a data uploading request of the electric power equipment, and inquiring a first public key of the electric power equipment.
Preferably, the server stores a mapping table describing a correspondence between the electric power device and the first public key, and updates the correspondence in the mapping table after receiving the first public key returned by the electric power device each time. Referring to step S13, a second asymmetric key including a second public key and a second private key is generated by the server for each of the electric devices, and the correspondence relationship between the second asymmetric key and the electric device is also described in the mapping table. Therefore, the server can determine the corresponding first public key by inquiring the mapping table according to the terminal identification information of the power equipment in the data uploading request.
S13-2, if the first public key of the power equipment is inquired and the first public key is in a preset valid period, judging that the power equipment meets the communication condition; if the first public key of the electric power equipment in the validity period is not inquired, judging that the electric power equipment does not meet the communication condition.
Specifically, the valid period may be set separately for each of the power devices, or the valid period may be set uniformly for a plurality of the power devices. The term calculation of the validity period may be from the time of generation of the first public key or from the time of reception of the first public key by the server.
The process of obtaining the first public key is referred to step S14. It is to be understood that, in the case where the flow shown in steps S11 to S17 is executed for the first time, the electric power device does not have the first public key yet, and it is determined that the electric power device does not satisfy the communication condition.
For example, it is assumed that the electric power devices include four electric power devices of electric meters a to D, in which the key validity period of the electric meter a is set to two hours (2 h). The method comprises the steps that an ammeter A sends a data uploading request to a server, the server inquires a first public key corresponding to the ammeter A in a mapping table according to an identification of the ammeter A in the data uploading request, and whether the service life of the first public key exceeds 2h or not is determined. If the time exceeds 2h, judging that the ammeter A does not meet the communication condition; and if the time does not exceed 2h, judging that the ammeter A meets the communication condition.
S14, if the power equipment does not meet the communication condition, sending a key updating signal to the power equipment to obtain a first public key returned by the power equipment; generating a second public key and a second private key, encrypting the second public key according to the first public key to obtain a public key ciphertext, and sending the public key ciphertext to the power equipment; and re-judging whether the power equipment meets the communication condition.
The power device locally generates a first asymmetric key including the first public key and a first private key after receiving the key update signal, and transmits the first public key to the server.
And after receiving the first public key, the server locally generates a second asymmetric key comprising the second public key and the second private key, encrypts the second public key by adopting the first public key to obtain a public key ciphertext and sends the public key ciphertext to the server. Preferably, each set of the second asymmetric key corresponds to a communication process of the server and one of the power devices. The asymmetric keys adopted when the server communicates with each electric power device are mutually independent, so that under the condition that a user purchases a new electric power device, the corresponding relation between the electric power device and the asymmetric keys recorded in the server can be updated by the new electric power device only needing to perform a communication process with the server once, the keys are matched without updating the asymmetric keys between the server and other electric power devices, and the access flow of the new electric power device is simplified on the basis of protecting the communication safety.
And S15, if the power equipment meets the communication condition, returning communication confirmation information.
And the communication confirmation information is used for enabling the power equipment to determine the monitoring parameters needing to be acquired according to the incidence relation so as to serve as the target parameters of the monitoring parameters needing to be acquired.
S16, acquiring an encryption parameter set sent by the power equipment according to the communication confirmation information; the encryption parameter set is an encryption data set obtained by encrypting with the first private key based on the electric power information collected by the electric power equipment.
The power equipment converts the acquired target parameters into Json format data by acquiring the target parameters, and encrypts the data by adopting the first private key to obtain the encryption parameter set.
The encrypted data set is ciphertext information obtained by encrypting each acquired target parameter by the power equipment according to a first private key corresponding to the first public key.
S17, decrypting the encrypted data set according to the first public key to obtain a plaintext data set; and sending the plaintext data set to the owner user and the target user shared by the power information.
And providing the plaintext data sets of all the bound electric equipment for the owner user according to all the electric equipment bound in the owner user information.
Specifically, the method can further include a query process of the power information, including acquiring a query instruction input by a user; and providing a plain text data set of the electric power equipment for the user according to the query instruction and the electric power information sharing joined by the user.
Specifically, the user-side process subscribes to the topics published by the APP side or the WEB side in a shared or real-time manner, and the data format is binary. Data content, such as information of TDS value, PH value, temperature, residual chlorine, voltage, current, temperature, smoke volume, positioning, opening and closing brake (manual and automatic). And after receiving the subscription information, analyzing the subscribed binary data format, and applying to the instruction of the hardware chip, so as to obtain the information of the corresponding power equipment according to the authority of the user.
Specifically, according to a preset alarm threshold of the power equipment, when the power information of the plaintext data set is judged to exceed the alarm threshold, safety alarm information is sent to the owner user and a target user shared by the power information.
According to the power information sharing method based on the Internet of things, provided by the first embodiment of the invention, whether the power equipment meets the communication condition is judged through the validity of the key of the power equipment, so that the authenticity and the reliability of the received data uploaded by the power equipment are improved; and by constructing power information sharing, convenience is provided for home owners, tenants and other home-related users to acquire home power information, and the home-related users can conveniently manage the power use of the homes.
