Description

Technical Field

[0001] The invention relates to a bank teller temporary storage box control system and a control method thereof. Background Art

[0002] Bank counters need to collect and withdraw banknotes / bills in some businesses, which usually requires manual processing of small change and entry into the system. However, manual processing of banknotes / bills and entry into the system requires many operational procedures and takes a long time, which affects the speed of counter business processing. At the same time, manual storage of banknotes / bills is prone to loss and is not secure enough.

[0003] At present, most bank counters use a change box to temporarily store banknotes / bills. When in use, it needs to be opened and closed manually to store banknotes / bills, which is complicated to operate. In addition, each change box is independent and similar in appearance, and it is easy to make mistakes and omissions if it relies on manual distinction. Summary of the invention

[0004] The object of the present invention is to provide a bank teller temporary storage box control system and a control method thereof which can avoid wrong or missed accounts and are easy to operate.

[0005] The technical solution for achieving the purpose of the present invention is:

[0006] A bank teller temporary deposit box control system comprises a control panel, a relay and a sensor; the control panel is installed in the bank teller temporary deposit box; the control panel is provided with an MCU, a serial communication module, a boost circuit, a switch circuit and a USB interface; the MCU is connected to a bank teller computer via the serial communication module; the USB interface supplies power to the control panel; the boost circuit receives a pulse signal from the MCU, and boosts a 5V voltage input from the USB interface to 12V and then transmits it to the switch circuit; the switch circuit transmits the 12V voltage sent by the boost circuit to the relay, and controls the on and off of the 12V voltage transmission by receiving a control signal from the MCU; the sensor senses whether the drawer of the bank teller temporary deposit box is ejected, and feeds back a signal to the MCU.

[0007] Furthermore, the chip model of the MCU is STC15F104W.

[0008] Furthermore, the chip model in the serial port communication module is SP3232.

[0009] Furthermore, a field effect transistor is used in the switch circuit to control the on and off of the circuit.

[0010] Furthermore, the field effect tube model in the switch circuit is IRF9540NS.

[0011] Furthermore, a light emitting diode is also provided on the control board; the light emitting diode is electrically connected to the USB interface.

[0012] Furthermore, the sensor adopts a micro switch; the micro switch cooperates with the drawer locking device of the bank teller temporary storage box.

[0013] A control method for a bank teller temporary storage box control system, comprising the following steps:

[0014] Step 1: Each bank teller temporary storage box has a unique serial number burned into the MCU of its control board before leaving the factory;

[0015] Step 2: During installation, the serial communication module of the bank teller temporary storage box is connected to the bank teller's computer and powered through the USB interface;

[0016] Step 3: Import the serial number of the bank teller's temporary storage box into the bank system through the bank teller's computer;

[0017] Step 4: When the box needs to be opened, the teller issues a command through the bank system on the computer, which contains the box opening command and the serial number corresponding to the bank teller temporary storage box that needs to be opened;

[0018] Step 5: After receiving the command through the serial communication module, the MCU of the bank teller temporary storage box first determines whether the serial number issued by the bank system is completely consistent with the serial number written by itself; if the sequences are consistent, the MCU sends a pulse signal to the boost circuit, so that the boost circuit boosts the 5V voltage to 12V, and at the same time, the MCU sends a box opening signal to the switch circuit, the switch circuit is turned on to transmit the 12V voltage to the relay, and the relay causes the drawer locking device of the bank teller temporary storage box to release the drawer, so that the drawer pops out; if the serial numbers are inconsistent, the MCU returns an error code to the bank system through the serial communication module;

[0019] Step 6: If the sequence is consistent, after the MCU sends a box opening signal to the switch circuit, the MCU reads the sensor signal to determine whether the drawer locking device of the bank teller temporary storage box has released the drawer, and returns the result to the bank system through the serial communication module.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects:

[0042] See Figure 3 The chip model in the serial communication module 1-2 is SP3232.

[0043] See Figure 4 The boost circuit 1-3 boosts the input 5V voltage to 12V through four unidirectional diodes and then transmits it to the switch circuit 1-4.

[0044] See Figure 5 The switch circuit 1-4 is connected to the boost circuit 1-3. The input voltage of the interface is 12V. The on-off control circuit is controlled by the field effect tube model IRF9540NS. The noise is small, the power consumption is low, and the temperature stability is good.
