The present invention will be described in detail with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic diagram of a charging and refunding method of a public rental house hydroelectric gas meter.
In the drawings: 1 is a water and electricity gas meter, 2 is a mobile phone, and 3 is a background server.
Detailed Description
Referring to the attached figure 1, the invention provides a charging and fee refunding method for a hydropower gas meter in a public rental house, which is based on the hydropower gas meter 1, a mobile phone 2 and a background server 3 and comprises a charging step and a fee refunding step.
In the application, direct data interaction does not exist between the water-electricity gas meter 1 and the background server 3, and the mobile phone APP in the mobile phone 2 is used as a medium for data interaction between the water-electricity gas meter and the background server. And keys are matched and arranged in the hydroelectric gas meter 1 and the background server 3 to ensure the safety of charging and returning.
The recharging step comprises the following steps:
and step c1, the user scans the two-dimensional code on the hydroelectric gas meter 1 through the mobile phone APP arranged in the mobile phone 2, so that the background server 3 binds the hydroelectric gas meter 1 and the mobile phone APP.
And c2, initiating a recharging operation to the background server 3 through the mobile phone APP, after confirming that the recharging amount is received, the background server 3 encrypts the recharging amount by using the public key and returns the recharging code generated by encrypting the public key to the mobile phone APP.
And c3, inputting the recharging code into the hydroelectric gas meter 1 through a key on the hydroelectric gas meter 1, decrypting the recharging code by the hydroelectric gas meter 1 by using a private key, displaying the recharging amount after decryption is successful, and supplying power, water or gas to a public rental house, otherwise, prompting the failure of recharging.
The above refund procedure includes the following two embodiments.
The first embodiment is as follows: and step t1, the user initiates a fee refunding operation to the background server 3 through the mobile phone APP, and the background server 3 sends a fee refunding authentication code to the mobile phone APP after obtaining a fee refunding request.
And step t2, inputting the refund authentication code into the hydroelectric gas meter 1 through a key on the hydroelectric gas meter 1, calculating the residual amount after the hydroelectric gas meter 1 identifies the refund authentication code, encrypting the residual amount by using a private key to generate a refund confirmation code, stopping supplying power, water or gas to a public rental house, and simultaneously clearing data in the meter.
And step t3, inputting the refund confirmation code into the mobile phone APP and sending the refund confirmation code to the background server 3, and after the background server 3 decrypts successfully, returning the remaining amount to the payment account bound with the mobile phone APP and simultaneously removing the binding with the mobile phone APP.
Example two: step t 1: a random number R1 used as a fee refunding request code is generated through a fee refunding key of the water and electricity gas meter 1, the random number R1 is sent to the background server 3 while fee refunding operation is initiated to the background server 3 through the mobile phone APP, the background server 3 generates a random number R2 after obtaining the random number R1, and the random number R2 is returned to the mobile phone APP as a fee refunding authentication code.
The step can also be that a fee refunding operation is initiated to the background server 3 through the mobile phone APP, and the background server 3 prompts and inputs a fee refunding request code generated through a fee refunding key of the water and electricity gas meter 1 through the mobile phone APP; a random number R1 serving as a fee refunding request code is generated through a fee refunding key of the water and electricity gas meter 1, then the random number R1 is sent to the background server 3 through the mobile phone APP, the background server 3 generates a random number R2 after obtaining the random number R1, and the random number R2 serves as a fee refunding authentication code and is returned to the mobile phone APP.
Step t 2: inputting a random number R2 into the hydroelectric gas meter 1 through a key on the hydroelectric gas meter 1, carrying out XOR operation on the random number R1 and the random number R2 by the hydroelectric gas meter 1 to obtain a result symmetric key M1, carrying out signature on the result symmetric key M1 by the hydroelectric gas meter 1 through a private key, encrypting the signed result symmetric key M1 and the residual amount to generate a refund confirmation code S1, displaying the refund confirmation code S1 through a display screen of the hydroelectric gas meter 1 (the display screen can display a period of time to ensure that a user has enough time to operate), stopping supplying power to a public rental house, supplying water or gas, and clearing data in the meter.
Step t 3: the charge returning confirmation code S1 is sent to the background server 3 through the mobile phone APP, the background server 3 decrypts the charge returning confirmation code S1 by using a public key to obtain a signed result symmetric key M1 and the residual amount, then exclusive OR operation is carried out on the R1 and the R2 to obtain a result symmetric key M1 ', signature verification operation is carried out on the signed result symmetric key M1 by using the result symmetric key M1', if signature verification is successful, the residual amount is returned to a payment account bound to the mobile phone APP, and otherwise, the charge returning failure is prompted, and the charge returning confirmation code S1 is input again.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
