Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 and FIG. 2, the first embodiment of the smart stored value card electromechanical device of the present invention is suitable for use with an inductive component 9. The sensing element 9 can be a card-like, label-like or mobile device built into a mobile phone. The sensing element 9 includes a read-write chip, which can be a contact interface or a contactless interface, such as FeliCa technology. The Mifare technology or the NFC technology, etc., the read/write chip stores a set of identification codes, and records a balance value and a credit value.

The smart stored value card electromechanical device is connected between a power supply device 8 and a load device 7. The power supply device 8 can provide power, and the load device 7 can receive power, such as an electrical product or a battery of an electric vehicle. The smart stored value card electromechanical device comprises an electric meter unit 1, a reading and writing unit 2, a billing unit 3, an error prompting unit 4, and a credit reminding unit 6.

The meter unit 1 includes a switch module 12 that can be driven to transfer power of the power device 8 to the load device 7, and a metering module 11 that can measure power to output a power consumption. In this embodiment, the switch module 12 is a common relay that can be used to control the transmission of power. Since the types of relays are numerous and are conventional technologies, they will not be described in detail herein.

The read/write unit 2 includes a detection module 21, an identification module 22, and a control module 23. When detecting the sensing component 9, the detecting module 21 can sense the identification code, the credit value and the balance value built in the sensing component 9. The identification module 22 has a built-in verification code corresponding to the identification code of the corresponding sensing element 9. When the detection module 21 senses the sensing component 9 , the identification module 22 matches the verification code. The control module 23 detects the sensing module 21 . When the sensing component 9 and the identification module 22 are aligned, the switch module 12 is driven to transmit power of the power device 8 to the load device 7. The sensing module 21 does not detect the sensing component 9 or the When the identification module 22 does not match, the switch module 12 is driven to stop transmitting power of the power supply device 8 to the load device 7.

The billing unit 3 is connected to the meter unit 1 and the read/write unit 2, and includes a storage module 31, a time module 32 for providing current time, a judging module 33, and a deduction module 34. A credit module 35 and a settlement module 36.

The determining module 33 can determine the balance value built in the sensing component 9 to determine whether the balance value is sufficient for deduction. The determining module 33 triggers the deduction mode when the balance value is sufficient to deduct the payment. Group 34, when the balance value is insufficient to debit, triggers the credit module 35 to be activated. In this embodiment, the determining module 33 can determine whether the balance value built in the sensing component 9 is lower than or equal to a certain value, for example, equal to 0, and when the balance value is lower than the predetermined value, Not enough to deduct money.

When the deduction module 34 is activated, the amount of electricity used by the meter unit 1 is calculated every time a certain amount of power is accumulated, and a normal use value is generated. When the credit module 35 is activated, the power consumption measured by the meter unit 1 is calculated every time the power consumption is accumulated for a specific amount, and a credit usage value is generated. In this embodiment, the debit module 34 multiplies the power usage by a normal usage rate to obtain the normal usage value, and the credit module 35 multiplies the power consumption by a credit. The usage rate is used to obtain the credit usage value, and the credit usage rate is greater than the normal usage rate, but the implementation is not limited thereto.

The settlement module 36 increases the credit usage value to the credit value to generate a new credit value, and deducts the normal usage value from the balance value to generate a new balance value, the settlement module 36 will record the new credit value, the new balance value and the current time in the storage module 31, and drive the reading and writing unit 2 to the new credit value, the new balance value and the current time. The integration is recorded on the inductive element 9.

The error prompting unit 4 is connected to the reading and writing unit 2 and can be driven to issue an error message. When the identification code does not match the verification code, the identification module 22 triggers the error prompting unit 4 to issue the error message.

The intelligent stored value card electromechanical device of the invention can be applied to household electricity, storage environment electricity, camping ground electricity, parking dock power, parking lot vehicle charging, indefinite user power, etc., the following carefully describes the wisdom stored value Step flow when using the card electromechanical device:

Step 50: Waiting for the card insertion. In this embodiment, the sensing component 9 is in the form of a card, and the reading and writing unit 2 further includes a card holder for inserting the sensing component 9 to remind the user to place the sensing. The position of the component 9, but if the sensing component 9 is a non-contact interface, the sensing component 9 can be placed adjacent to the read/write unit 2 as long as the read/write unit 2 can sense the sensing component 9 Yes, it is not limited to this embodiment. When the sensing element 9 is inserted into the reading and writing unit 2, the process proceeds to step 51.

Step 51: Card identification, when the sensing unit 2 detects the sensing element 9, it will match whether the identification code of the sensing element 9 matches, if the comparison does not match, it will proceed to step 52; if the sensing is detected When element 9 matches the alignment, step 53 is entered.

Step 52: The read/write unit 2 does not match, for example, the user obtains the sensing component 9 corresponding to the other smart stored value card electromechanical device, which causes the read/write unit 2 to be inconsistent. At this time, the reading The writing unit 2 drives the error prompting unit 4 to issue the error message to remind the user to replace the sensing element 9.

Step 53: The read/write unit 2 matches the match. At this time, the read/write unit 2 drives the electric meter unit 1 to transmit the power of the power supply device 8 to the load device 7, and during the power supply process, the charge unit 3 Determining whether the balance value is sufficient to deduct, if the balance value is sufficient to deduct, the deduction module 34 is activated to be charged in a normal deduction manner; conversely, if the balance value is insufficient to deduct money, Billing is done by credit.

For example, if the current balance value is 10, the charging unit 3 activates the debit module 34 to charge in a normal debit manner, and the debit module 34 accumulates the specificity in the power consumption. When the magnitude is, for example, 0.1 kWh, the normal use value is calculated and output, and the process proceeds to step 54.

Step 54: The billing unit 3 performs settlement, and the billed new balance value and the new credit value are recorded in the storage module 31 and the sensing component 9 in the current time, and the steps are entered. 55.

Step 55: The read/write unit 2 determines whether the sensing component 9 is removed, that is, whether the sensing module 9 detects the sensing component 9. If the sensing component 9 is not removed, the sensing component 9 is detected. Going back to step 53, step 53 to step 55 are performed again. If the sensor element 9 is not detected, that is, the sensing element 9 is not detected, the process proceeds to step 56.

If the user does not remove the sensing component 9, the steps 53 to 55 are repeatedly executed until the charging unit 3 determines in step 53 that the balance value is 0, the charging unit 3 is changed to start the device. The account module 35 is charged by way of credit. Similarly, the credit module 35 calculates and outputs the credit usage value when the power consumption reaches 0.1 kWh. Since the charge rate of the credit module 35 is relatively high, relatively expensive electricity charges are incurred. Therefore, when the credit module 35 is activated, the credit reminding unit 6 is also driven to issue the credit notice message. Remind users that billing is currently performed at a higher rate.

Step 56, when the sensing element 9 is removed, for example, when the user wants to leave and pulls away from the sensing element 9, the reading and writing unit 2 drives the switch module 12 to stop transmitting power of the power device 8 to the load device. 7. Since the balance value and the credit value are recorded on the sensing element 9, the user can make a payment or add value according to the sensing element 9, which is quite convenient.

It should be noted that the error prompting unit 4 and the credit reminding unit 6 of the embodiment may be an LED light or a buzzer, and may respectively send an error message and a caution notice message as a warning light or a warning sound to Reach reminders and tips.

It is worth mentioning that the read/write chip of the sensing component 9 can also store an array identification code for comparison, and can also record several balance values and several credit values as a backup to reduce the single balance value. A situation in which data is corrupted or erroneous with a single credit value.

In addition, the meter device and the sensing element 9 are also designed to be offline, that is, when the user brings the sensing element 9 close to the reading and writing unit 2, the meter device can be operated and selected. The sensing element 9 is configured to be in the state of being inserted or pulled out, and then the sensing element 9 can be removed. The reading and writing unit 2 determines whether the sensing component 9 is detected according to whether the meter device is currently in a card state or a card-carrying state. If the card state indicates that the card is detected, if the card is in a state, the card is undetected. Measured.

Specifically, in step 50, the user may first cause the sensing element 9 to be in proximity to the reading and writing unit 2 to be sensed, and set to the card state, so that the meter device starts to transmit power in step 53, and then the user The sensing element 9 can be removed, and in step 54, since the billing unit 3 has stored the balance value and the credit value of the sensing element 9, it can be based on the stored balance value and the credit value. Billing and settlement, and stored in the billing unit 3.

In step 55, the reading and writing unit 2 determines whether the sensing element 9 is removed or not, according to the current state of card insertion or card removal, and if it is in the card state, it is determined not to be unplugged until the user makes the sensing again. The component 9 is in proximity to the read/write unit 2 to sense and set the current card release state. In step 54, the billing unit 3 records the stored balance value and the credit value in the sensing component 9 and then enters. Step 56 The meter device stops transmitting power.

In summary, the smart stored value card electromechanical device of the present invention, through the design of the charging unit 3, can use the credit method to perform billing when the balance value is insufficient to deduct the payment, so that the user can When the balance value is deducted, the load device 7 can still be used continuously, and the payment and the value are added again at a suitable time, which is quite convenient, so that the object of the present invention can be achieved.

Referring to FIG. 3 and FIG. 4, the second embodiment of the smart stored value card electromechanical device of the present invention is different from the first embodiment in that the meter unit 1 of the second embodiment does not include the switch module. The meter unit 1 will constantly transfer the power of the power supply unit 8 to the load device 7. The smart stored value card electromechanical device further includes a card prompting unit 5 that is connected to the reading and writing unit 2 and can be driven to issue an unplugged message, and the reading and writing unit 2 does not include the control module.

In addition, when the detecting module 21 does not detect that the sensing component 9 or the identification module 22 does not match, the determining module 33 determines that the balance value is insufficient to deduct. When the detecting module 21 does not detect that the sensing component 9 or the identification module 22 does not match, the accounting module 36 also uses the credit value calculated by the credit module 35. Increasing the credit value to settle the new credit value, but will not drive the read/write unit 2 to replace the balance value recorded by the sensing element with the new balance value and the new credit value. Account value. When the detecting module 21 detects the sensing component 9 and the recognition module 22 matches, the clearing module 36 drives the reading and writing unit 2 to use the new balance value and the new one at the time of settlement. The credit value replaces the balance value and the credit value recorded by the sensing element 9.

When the embodiment is used, there are three situations. The first is that the user has not inserted the sensing component 9 into the card slot, and the smart stored value card electromechanical device transmits power and charges; the second is that the user is inserted incorrectly. The sensing component 9, the smart stored value card electromechanical device transmits power and charges; the third is that the user inserts the correct sensing component 9, and the smart stored value card electromechanical device transmits power and charges.

First, the first case will be described. The operation flow of the smart stored value card electromechanical device when the user has not inserted the sensing element 9 into the card holder. Step 60: Whether the card is inserted, the read/write unit 2 detects whether the sensing component 9 is inserted into the card slot. If the sensing component 2 does not detect the sensing component 9, the process proceeds to step 61. If the reading and writing unit 2 detects the sensing element 9, it will proceed to step 66. Since the user has not inserted the sensing element 9 into the card holder at this time, the process proceeds to step 61.

Step 61: The read/write unit 2 determines whether a prompt is to be issued. If the read/write unit 2 detects the sensing element 9, it proceeds to step 63. If the read/write unit 2 does not detect the sensing element 9, Will proceed to step 62. Since the sensing unit 9 does not detect the sensing element 9 at this time, the process proceeds to step 62: the card prompting unit 5 is driven to issue the unplugged message, so that the user can be reminded to insert the card as soon as possible. Then, the process proceeds to step 63.

Step 63: Similar to step 53 (see Fig. 2) of the first embodiment, but does not include transmitting power. The billing unit 3 determines whether the balance value is sufficient to deduct, and if the balance value is sufficient to deduct, the deduction module 34 is activated to charge in a normal deduction manner; conversely, if the balance value is insufficient The debit will activate the credit module 35 and will be billed by credit. Since the reading and writing unit 2 has not detected the sensing element 9, it is determined that the balance value is not enough to deduct, and the charging unit 3 will charge in the form of credit. After the charging is completed, the process proceeds to step 64.

Step 64: The settlement module 36 increases the credit usage value calculated by the credit module 35 to the credit value when the detection module 21 does not detect the sensing component 9, but The read/write unit is not driven to record, and then proceeds to step 65.

Step 65: The read/write unit 2 determines whether the sensing component 9 is removed, that is, whether the sensing unit 2 detects the sensing component 9. If the sensing component 9 is removed, that is, the sensing component 9 is not detected, it will be returned. Go to step 60. If it is not removed, that is, the sensing element 9 is detected, the process proceeds to step 66.

Next, the second case will be described, in which the user operates the smart stored value card electromechanical device when the wrong sensing element 9 is inserted into the card holder. In step 60, the read/write unit 2 detects the sensing element 9 and proceeds to step 66.

Step 66: When the sensing unit 2 detects the sensing element 9, it will match whether the sensing code is matched. If the comparison does not match, the process proceeds to step 67; if the sensing element 9 is detected and compared If it matches, it will go to step 61. If the sensing element 9 inserted by the user is incorrect or does not correspond to the smart stored value card electromechanical device, step 67 is entered.

Step 67: The read/write unit 2 does not match, and the read/write unit 2 drives the error prompting unit 4 to issue the error message to remind the user to replace the sensing element 9, and then proceeds to step 61. In step 61, since the reading and writing unit 2 has detected the sensing element 9, it proceeds to step 63. In step 63, since the read/write unit 2 does not match, the balance value of the sensing element 9 is not read, so that the balance value is determined to be insufficient to deduct, and the charging unit 3 will be credited. The way to charge, after the billing is completed, will proceed to step 64.

In step 64, the settlement module 36 may increase the credit usage value calculated by the credit module 35 to the credit value when the identification module 22 does not match, but still does not drive The reading and writing unit replaces the balance value and the credit value recorded by the sensing element with the new balance value and the new credit value, and proceeds to step 65. In step 65, the reading and writing unit 2 detects The inductive element 9, thus will return to step 66.

Finally, in the third case, when the user inserts the correct sensing element 9 into the card holder, the intelligent stored value card electromechanical device operates. In step 60, the read/write unit 2 detects the sensing element 9 and proceeds to step 66. In step 66, the read/write unit 2 matches the pair and proceeds to step 61. In step 61, since the reading and writing unit 2 has detected the sensing element 9, it proceeds to step 63.

In step 63, since the read/write unit 2 has detected the balance value of the sensing element 9, it is determined whether the balance value is sufficient for deduction, and when the balance value is sufficient to deduct the payment, the deduction mode is activated. Group 34 is charged in a normal debit manner; conversely, when the balance value is insufficient to debit, the credit module 35 is activated to bill by credit. After the billing is completed, the process proceeds to step 64.

In step 64, when the detecting module 21 detects the sensing component 9 and the recognition module 22 matches, the accounting module 36 uses the credit calculated by the credit module 35. The value is increased to the credit value to settle the new credit value, and the normal usage value is also deducted from the balance value to settle the new balance value, and the new credit value is The new balance value is integrated with the current time in the storage module 31 and the sensing element 9, and proceeds to step 65. In step 65, the read/write unit 2 detects the sensing element 9, and therefore returns to step 66.

Through the above design, the power of the power supply device 8 can be continuously supplied to the load device 7, and in the case of no card insertion or card error, billing is performed, and the calculated fee is accumulated. The credit value, at the same time, the smart stored value card electromechanical device also reminds the user to insert the sensing element 9 or replace it with the correct sensing element 9 as soon as possible through the unplugged card message or the error message to avoid continuous The way of credit is charged.

After the user inserts the correct sensing element 9, the smart stored value card electromechanical device stores the previously accumulated credit value and the balance value into the sensing element 9 so that the sensing element 9 stores The credit value and the balance value are synchronized with the credit value and the balance value stored in the smart stored value card electromechanical device, and the user can carry the sensing component 9 to any stored value machine to view the recorded component 9 at any time. The credit value and the balance value, and the payment or the value of the payment, if the user can use the power without inserting the card, the card is wrong, or the balance value is deducted, the invention can be achieved. purpose.

It is to be noted that the electric meter device of the second embodiment and the inductive element 9 are also of an off-line design as in the first embodiment, with the difference that the electric meter device continuously transmits power.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
