Description

Technical Field

[0001] The invention belongs to the technical field of valve control, and relates to a remote-controlled intelligent valve based on charging information and a control method thereof. Background Art

[0002] In the prepaid model, the necessity of valve control mainly stems from the need to manage and control the use of resources. This model allows users to use resources according to the amount they have purchased, and the valve control system ensures that users do not exceed their prepaid amount. In the prepaid water meter system, the valve will automatically close when the user's account balance is exhausted, preventing further water flow, which has certain limitations.

[0003] In the prepaid mode, the current control of immediate valve closure for arrears has some defects and disadvantages. First, this method may cause users to suddenly lose basic living needs such as water or gas supply, which brings inconvenience to users. Secondly, because in some special cases, users may fail to recharge in time due to negligence or other reasons, immediate closure of the valve may cause trouble in some scenarios where water or gas is urgently needed. In addition, if the system fails, mistakenly shutting down normal users will also cause user complaints and increased maintenance costs. Therefore, when implementing the control of immediate valve closure for arrears, it is necessary to comprehensively consider user rights and system stability, and take more intelligent and humane measures to balance the interests of management and users. Summary of the invention

[0004] In view of the above problems existing in the prior art, the present invention provides a remote-controlled intelligent valve based on charging information and a control method thereof, which are used to solve the above technical problems.

[0005] In order to achieve the above purpose and other purposes, the technical solution adopted by the present invention is as follows:

[0006] A first aspect of the present invention provides a remote-controlled intelligent valve based on charging information, comprising:

[0007] (1) providing a valve control device, wherein the valve control device includes an intelligent control unit having an embedded microprocessor for receiving and processing data, and a wireless communication module for communicating with a remote payment system;

[0008] (2) configuring a user account database in the intelligent control unit to store user prepayment information, including user identification, account balance, and payment history;

[0009] (3) receiving prepaid information from the user, including the user's payment amount, through the wireless communication module, matching and verifying the information, and after the payment amount is confirmed to be correct, the intelligent control unit transmits the control instruction to the valve execution unit;

[0010] (4) The valve actuator adjusts the opening state of the valve according to the received control command, thereby controlling the flow of the fluid;

[0011] (5) The intelligent control unit updates the account balance in the user account database in real time according to the actual opening parameters of the valve, and feeds back the balance information to the user through the wireless communication module;

[0012] (6) When the balance in the user's account is insufficient to support the next fluid flow, the intelligent control unit automatically sends a reminder to the user and evaluates the user based on the payment history to obtain the user's pre-allowed fluid usage. When the user's pre-allowed water usage is consumed and no new prepayment information is received, the valve is closed to stop the fluid flow.

[0013] As a preferred solution, an account is registered for a user in the target area in the intelligent control unit, and a specific identification code is assigned to the user, and the identification code is bound to the user identification of the corresponding intelligent valve device to form a user identification.

[0014] As a preferred solution, verify the user's payment amount. The specific verification process is as follows:

[0015] Based on the payment history records stored in the user account database, extract the payment amounts corresponding to each payment made by the user's corresponding payment account number in the corresponding historical period;

[0016] Then according to the analytical formula The analysis results show that the user's payment amount abnormal assessment coefficient H 金额 , where c represents the number of each payment in the historical period, c = 1, 2, ... b, ε represents the amount to be paid by the user, δ c represents the payment amount corresponding to the cth payment of the user's corresponding payment account number in the corresponding historical period, and Δε represents the preset allowable difference in amount;

[0017] If the user's payment amount abnormality assessment coefficient is greater than the set reference amount abnormality assessment coefficient, it indicates that the user matching verification has failed, otherwise it indicates that the user matching verification has passed.

[0018] As a preferred solution, the account balance in the user account database is updated. The specific update process is as follows:

[0019] Identify the flow rate of the fluid used by the user in a single use. The specific identification process is as follows:

[0020] According to the turbine flowmeter arranged in the pipeline, the fluid flow data is collected in real time, and the collected fluid flow data is preprocessed. The instantaneous flow rate of the user's single use of the fluid is calculated using the calculation formula Q = K × f, K represents the predefined instrument coefficient of the turbine flowmeter, f represents the pulse frequency, and the specific calculation formula is:

[0021] The sensor is used to monitor the total number of pulses in a single use time period of the user and the corresponding generation time point of each pulse. The generation time points corresponding to each pulse are subtracted from each other to obtain the time interval corresponding to each pulse, which are recorded as t1, t2, t3, ..., tn respectively, and the pulse frequency is calculated from this.

[0022]

[0023] , n is the total number of pulses in a single usage time period of the user;

[0024] According to the turbine flowmeter arranged in the pipeline, the starting time point T0 and the ending time point T1 of the user's single use of the fluid are obtained, and the cumulative flow rate Z=Q×(T1-T0) of the user's single use of the fluid is calculated;

[0025] The accumulated flow rate of the fluid used by the user in a single time is multiplied by the unit price corresponding to the preset unit cubic meter flow rate, thereby obtaining the usage amount of the fluid used by the user in a single time;

[0026] The total amount in the user's account is subtracted from the amount of fluid used by the user for a single time, and the result of the subtraction is fed back to the user's account.

[0027] As a preferred solution, users are evaluated based on their payment history. The specific evaluation process is as follows:

[0028] Extract the payment dates of each user from the payment history stored in the user account database, compare them with each other, and obtain the average payment time difference of each payment of the user T c is the date when the user pays the fee for the cth time, T1, T2, T c-1 are the dates of payment of the user's first, second and c-1th payment respectively;

[0029] The average time difference of each payment of the user is used to calculate and evaluate the user's payment punctuality coefficient b is the total number of payment times, e is a natural constant, H1, H2, H c-1 They are the average time differences for the user’s 1st, 2nd and c-1th payments respectively.

[0030] As a preferred solution, the user's pre-limited fluid usage amount is obtained, and the specific acquisition process is as follows:

[0031] The user's payment punctuality coefficient is compared with the predefined payment punctuality coefficient evaluation interval corresponding to each credit level. If the user's payment punctuality coefficient is within the predefined payment punctuality coefficient evaluation interval corresponding to a certain credit level, the credit level is used as the user's signal level;

[0032] The signal level of the user is compared with the pre-allowed fluid usage amount values ​​corresponding to the predefined credit levels, thereby obtaining the pre-allowed fluid usage amount of the user.

[0033] A second aspect of the present invention provides a remote control intelligent valve control method based on charging information, comprising the following steps:

[0034] A valve control device is provided, wherein the valve control device includes an intelligent control unit having an embedded microprocessor for receiving and processing data, and a wireless communication module for communicating with a remote payment system;

[0035] A user account database is configured in the intelligent control unit to store user prepayment information, including user identification, account balance and payment history;

[0036] The prepaid information from the user is received through the wireless communication module, including the user's payment amount, and the information is matched and verified. After the payment amount is confirmed to be correct, the intelligent control unit transmits the control instruction to the valve execution unit;

[0037] The valve actuator adjusts the opening state of the valve according to the received control command, thereby controlling the flow of the fluid;

[0038] The intelligent control unit updates the account balance in the user account database in real time according to the actual opening parameters of the valve, and feeds back the balance information to the user through the wireless communication module;

[0039] When the balance in the user's account is insufficient to support the next fluid circulation, the intelligent control unit automatically sends a reminder to the user, and evaluates the user based on the payment history to obtain the user's pre-allowed fluid usage. When the user's pre-allowed water usage is consumed and no new prepayment information is received, the valve is closed to stop the fluid circulation.

[0040] A third aspect of the present invention provides a remote control intelligent valve device based on charging information, comprising an electronic device and a computer-readable storage medium;

[0041] The electronic device comprises a processor, a memory and a communication bus, wherein the memory stores a computer-readable program executable by the processor;

[0042] The communication bus realizes the connection and communication between the processor and the memory;

[0043] When the processor executes the computer-readable program, the steps in the above-mentioned remote-controlled intelligent valve based on charging information and the control method thereof are implemented;

[0044] The computer-readable storage medium stores one or more programs, and the one or more programs can be executed by one or more processors to implement the steps in the above-mentioned remote-controlled intelligent valve based on charging information and the control method thereof.

[0046] The present invention provides a remote-controlled intelligent valve based on charging information and a control method thereof. The prepayment information from the user is received through a wireless communication module. After the payment amount is confirmed to be correct, the intelligent control unit transmits the control instruction to the valve execution unit. The valve execution unit adjusts the opening state of the valve according to the received control instruction, thereby controlling the circulation of the fluid. The intelligent control unit updates the account balance in the user account database in real time according to the actual opening parameter of the valve, and feeds back the balance information to the user through the wireless communication module. When the user account balance is insufficient to support the next fluid circulation, the intelligent control unit automatically sends a reminder to the user, and evaluates the user according to the payment history record to obtain the user's pre-allowed fluid usage. When the user's pre-allowed water consumption is consumed and no new prepayment information is received, the valve is closed to stop the fluid circulation. In the prepayment mode, for users with good credit, even if they are in arrears for a short time, the valve is not immediately closed, but a certain grace period is provided, which helps to maintain a good user experience and service continuity. First of all, this approach can avoid users suddenly losing basic living needs such as water supply or gas supply due to short-term arrears, thereby reducing user inconvenience and complaints. Secondly, the grace period can give users the opportunity to recharge in time and avoid unnecessary interruption of service due to negligence or other reasons, especially in urgent emergency situations, which can provide a certain degree of flexibility and security. In addition, this strategy can also help reduce the risk of shutting down normal users due to system failure or misoperation, thereby reducing management and maintenance costs and improving service stability and reliability. Therefore, implementing a grace period policy for users with good credit can better meet the actual needs of users while balancing the interests of management and users, and improve the overall service level and user satisfaction.
