and judging that the last charging task is not finished according to the fact that the read first time is larger than 0, starting charging, and continuing to count down by taking the read first time as a starting point.
In the normal charging process, the charging remaining time of the terminal is saved at intervals. And if the power failure occurs in the middle, when the shared charging wire is electrified again, reading the charging remaining time stored last time, namely the remaining time stored last time before the power failure. If the read remaining time is larger than 0, the electronic switch is automatically turned on to start charging, and counting down is continued from the read last stored charging remaining time. If the read remaining time is 0, namely no remaining time exists, the last charging task is judged to be normally finished.
According to the scheme, the remaining time is read after the shared charging wire is connected to the 220V mains supply again, the remaining time is found, the power failure in the last charging process is judged, and the shared charging wire is automatically started to continue charging the terminal. The trouble that the user scans the codes again and the economic loss of paying again are avoided, the user is prevented from being unaware of abnormal power failure in the charging process and delaying the use of the user, the benefit of the user is guaranteed, the user experience is improved, and the customer complaint is reduced.
For the operator, it is not desirable that the next user can continue to use the remaining time that the previous user did not use after the previous user left the remaining time that was not used up, and therefore, there is a further need to identify whether the remaining time that was not used up is of the same user or of the same type or of the same handset. For this reason, a further need exists to detect the recharged terminal.
Further, when the first time of reading is greater than 0, reading a first voltage stored last time, wherein the first voltage is a voltage detected before the first time is stored;

Detailed Description
In order to make the implementation, technical solutions and advantages of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments selected may be preferred embodiments, but that not all embodiments are possible. 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 specification.
Fig. 1, a preferred embodiment disclosed according to the first aspect of the present invention.
S01: the last saved first time Tr, which is the charge remaining time, is read.
The charging remaining time is a dynamic time in the charging process, and is the remaining charging time collected at fixed time intervals or a certain frequency, for example: the charging time selected by the user is 2 hours, and the charging remaining time is stored every 20 minutes, then the data are stored in sequence: 120 minutes, 100 minutes, 80 minutes, 60 minutes, 40 minutes, 20 minutes, 0 minute. This example is illustrative and not limiting as the scheme is to preserve the remaining time at this frequency. If power failure occurs in the charging process, when the 220V mains supply is accessed when the power is on and started, the first time Tr stored last time is read, and the last remaining time Tr stored before the power failure occurs is read.
S02: determine if Tr > 0?
And judging that the last charging task is not finished according to the fact that the read first time is larger than 0, starting charging, and starting to count down by taking the read first time as a starting point.
And judging that the last charging task is finished according to the read first time of 0, and waiting for an instruction, wherein the instruction is a charging starting instruction triggered according to user operation.
For example: reading the last stored charging remaining time as 60 minutes, considering that the power failure occurs when the remaining time is 60 minutes, automatically switching on the electronic switch without any operation of a user, and continuously counting down the charging with the remaining time taking 60 minutes as a starting point. The actual time error is ignored in this scheme. For example: the user selects the charging time to be 2 hours, the shared charging line stores the residual charging time every 20 minutes, the power failure occurs when the user charges for 30 minutes, the stored data is 140, and after the power is re-electrified, the residual charging time is 140 and is unrelated to the middle power failure time. And judging whether power failure occurs or not according to whether the residual time is read during power-on, if the residual time is read, determining that the power failure occurs, automatically switching on the electronic switch, avoiding the user from operating again, and continuously counting down the residual time from the read time, so as to avoid the loss of the user caused by the power failure.
It is undesirable for the operator that the next user can continue to use the remaining time that the previous user did not use after the previous user left the unused time. For example: the first user selects the charging time to be 2 hours, the power is cut off after the charging is carried out for 20 minutes, and the user dials away the terminal to leave. And after the call comes, the second user accesses the terminal, the shared charging line reads the stored residual 140 minutes, and the second user can use the residual time of the first user without any operation. To avoid this, it is further desirable to identify whether the unspent remaining time is for the same user or the same type or the same handset.
S03: reading a last saved first voltage Vs when the read first time Tr > 0, the first voltage Vs being a voltage detected before saving the first time;
s04: detecting a second voltage Vc, wherein the second voltage Vc is the currently detected voltage;
and judging that the current terminal is the terminal which has not finished the last charging task according to the fact that the second voltage is approximately equal to the first voltage, starting charging, and starting countdown by taking the read first time as a starting point.
And according to the fact that the second voltage is not approximately equal to the first voltage, judging that the current terminal is not the terminal which is not finished by the last charging task, and clearing and storing the reading time.
When step S02 is executed, the power-down problem can be solved, and the benefit of the user can be ensured. Further, in order to guarantee the benefit of an operator, when the reading Tr is larger than 0, the situation that power failure occurs in the charging process is judged, and a terminal identification step is added before the automatic conduction of the electronic switch is executed to start charging. The charging wire is connected to the terminals of different models, and equivalent input impedance is different. By utilizing the rule, when the terminals are connected into the shared charging wire, different terminals can be distinguished by comparing the detected voltages. According to the scheme, the storage terminal is connected to the shared charging line and starts the voltage Vs detected before charging. When the power is on after the power failure, reading the remaining time Tr stored before the power failure and the currently detected voltage Vc, if the remaining time exists and the voltage Vc detected again is almost the same as the voltage Vs stored before the power failure, judging that the terminal is the same terminal, automatically continuing charging, and if the difference between Vc and Vs is larger, judging that the terminal is not the same terminal, clearing and storing the read time.
In this control scheme, the method further comprises the steps of:
s05, starting charging and counting down by taking the read first time as a starting point;
storing the current charging remaining time according to a set frequency;
when the current charging remaining time is 0, the countdown is finished,
and closing charging and waiting for an instruction, wherein the instruction is a charging opening instruction triggered according to user operation.
Further, when charging is started, the read remaining time of the last storage is continued, and the current remaining time of charging is continuously stored according to the set frequency. And when the countdown is finished, the charging is closed, and the next user is waited to scan the code and start the charging.
S06: upon receipt of the instruction;
saving a second time Te, wherein the second time Te is the charging time selected by the user operation, and counting down the second time;
detecting the current voltage;
and according to the detected current voltage being greater than 0, judging that a terminal is accessed to the shared charging line, starting charging, storing the current voltage value, and storing the charging remaining time according to the set frequency.
Judging whether a non-terminal accesses the shared charging wire according to the detected current voltage not greater than 0, storing the charging remaining time according to the set frequency and detecting the current voltage;
and if the current voltage is detected to be greater than 0 before the residual time is over, judging that a terminal is accessed to the shared charging wire, starting charging, storing the current voltage value, and storing the residual time of charging according to the set frequency.
Further, when a charging starting instruction is received, the charging time selected by a user is saved, if voltage is detected, a terminal is accessed, charging is started, and the detected voltage and the charging remaining time are saved. If no voltage is detected, no terminal is connected, and the voltage is detected circularly and the remaining time is saved until the detection state is changed. That is, after the user has scanned the code for payment, the countdown is performed regardless of whether the user has accessed the terminal. For example: the user scans the code for 2 hours, fills 30 minutes, dials out the terminal, accesses the terminal after 30 minutes, and the remaining time is 1 hour.
It will be understood that the invention is not limited to the precise arrangements described above and shown in the drawings and that various modifications and changes may be made without departing from the scope of the invention. The scope of the invention is limited only by the appended claims.
