Abstract
Description
Technical Field
[0001] This application relates to the field of financial technology, and more specifically, to a bank counter cash register device. Background Technology
[0002] Currently, bank counters typically have a cash register for handling cash, documents, and certificates. These can be either open-type or push-pull type. Taking the push-pull type as an example, its structure is simple, consisting of an arc-shaped groove and a sliding plate covering it. In use, the side of the sliding plate with the slider faces the staff member, who pushes the plate towards them to allow customers to place items into the groove. The staff member then pushes the plate back towards them, allowing them to retrieve the items. Simultaneously, pushing the plate causes a spring-loaded pin to insert into a socket, securing the plate and sealing the groove from the outside, thus enhancing security.
[0003] However, the aforementioned POS equipment requires manual pushing and pulling of a sliding board to complete the item transfer operation. In some scenarios, it may be inconvenient for users to push and pull the sliding board with both hands, resulting in low efficiency in item transfer.

Figure 1 This is a cross-sectional schematic diagram of a bank counter cash register device provided according to an embodiment of this application, such as... Figure 1 As shown, the POS device includes: a POS channel, a ranging module, and a control device.

[0072] Optionally, in this embodiment, the distance between the deployment locations of the first transmitter and the first receiver is less than a first deployment distance threshold, and the distance between the deployment locations of the second transmitter and the second receiver is less than a second deployment distance threshold. Since ultrasonic waves are highly directional, in order for the receiver to receive the probe waves emitted by the transmitter, the receiver and the transmitter need to be deployed close to each other.
[0073] Optionally, in this embodiment, the first ranging sensor and the second ranging sensor can be ultrasonic sensors, laser sensors, or other ranging sensors capable of detecting distance.
[0074] Taking ultrasonic sensors as a ranging sensor as an example, ultrasonic sensors are sensors developed using the characteristics of ultrasound. Sound waves are the propagation form of the mechanical vibration state of an object. Ultrasound refers to sound waves with a vibration frequency greater than 20,000 Hz, and its vibration frequency per second is very high. Ultrasound is a mechanical oscillation in an elastic medium, and it has two forms: transverse oscillation (transverse waves) and longitudinal oscillation (longitudinal waves). In industrial applications, longitudinal oscillation is mainly used. Ultrasound can propagate in gases, liquids, and solids, and its propagation speed varies. In addition, it also exhibits refraction and reflection phenomena, and attenuates during propagation.
[0075] The application of ultrasonic sensors in ranging systems involves the following methods: The average voltage of the output pulse is taken; this voltage (whose amplitude is basically fixed) is proportional to the distance, and the distance can be measured by measuring the voltage. The width of the output pulse is measured, i.e., the time interval t between the emitted and received ultrasonic waves; therefore, the measured distance is S = 1 / 2vt. If high ranging accuracy is required, temperature compensation should be used for calibration. Ultrasonic ranging is suitable for high-precision medium- to long-distance measurements.
[0076] Optionally, in the bank counter cash register equipment provided in the embodiments of this application, the cash register equipment further includes: a power supply, wherein the power supply is used to provide power to the ranging module and the control device.
[0077] Optionally, in this embodiment, Figure 7 This is a schematic diagram of the power supply structure provided according to an embodiment of this application, such as... Figure 7 As shown, the power supply can provide power to the ranging module and control device to meet the requirements of distance detection and switching operations.
[0078] It should be noted that the bank counter cash register device proposed in this application mainly consists of the following parts:
[0079] (1) Cash register slot and hinge (which can be understood as the aforementioned cash register channel)
[0080] (2) Ultrasonic sensor (which can be understood as the ranging module mentioned above)
[0081] (3) The black box consists of a low-noise motor, a sensitivity adjustment module, a microcontroller, and a power supply (which can be understood as the aforementioned control device).
[0082] (4) Other components such as drive belts (which can be understood as the aforementioned drive motor and transmission device)
[0083] The bank counter's cash register equipment has two ultrasonic sensors attached to the glass above the cash register slot (facing the customer and the teller respectively). A small black box is placed below the recess of the cash register slot, which contains a microcontroller and a battery-powered power supply. The microcontroller is connected to a motor through a circuit composed of electronic components such as gate circuits and current amplifiers. The motor can drive a conveyor belt to pull up the hinge of the cash register slot.
[0084] Figure 8 This is a schematic diagram illustrating the working mode of the cash register device according to the embodiments of this application, such as... Figure 8 As shown, the entire POS system mainly operates in the following modes:
[0085] An ultrasonic sensor is installed on the glass at both the customer's and teller's ends. When the customer or teller approaches the set range—that is, when the reflected wave originates from a set angle on the teller's side, the distance is within a set value range on the teller's side, and the reflected wave is within a set frequency range; or when the reflected wave originates from a set angle on the customer's side, the distance is within a set value range on the customer's side, and the reflected wave is within a set frequency range—the ultrasonic sensor transmits an electrical signal to a logic circuit composed of a gate circuit and a microcontroller. The generated electrical signal is amplified by a current amplifier and connected to a motor circuit via a voltage switch, driving a low-noise motor to rotate, which in turn drives a track (or hinge, etc.) to open the hinge. When the customer or teller moves away from the ultrasonic sensor, the electrical signal stops, causing the motor to stop rotating via the same link.
[0086] The cash register slot and hinge are the basic hardware components of this invention. The ultrasonic sensor detects an object within a certain range and converts it into an electrical signal input circuit. This electrical signal input circuit can be understood as the aforementioned control device, which controls the opening and closing state of the cash register slot to match the target distance. In this application, the function of controlling the opening and closing state of the cash register slot to match the target distance is achieved by combining the ultrasonic sensor with the electrical signal input circuit. The detection range of the ultrasonic sensor should be greater than 10 meters. The ultrasonic sensor includes an ultrasonic transmitter and an ultrasonic receiver. The ultrasonic transmitter emits ultrasonic waves, and the ultrasonic receiver senses the ultrasonic waves from the ultrasonic transmitter and activates a relay. The circuit structures of the ultrasonic transmitter and the ultrasonic receiver are described below:
[0087] Ultrasonic transmitter: Figure 9 This is a circuit diagram of an ultrasonic transmitter provided according to an embodiment of this application, such as... Figure 9The ultrasonic transmitter parts list is as follows: IC1 = NE555 timer IC, VR1 = 10k variable resistor, R1 = 4.7k resistor, R2 = 18k potentiometer, R3 = 1k resistor, R4, R5 = 220 ohm resistors, C1 = 680 picofarad capacitor, C2 = 0.01uf capacitor, D1, D2 = 1N4148 diodes, T1 = SL100NPN transistor, T2 = SK100PNP transistor, S1 = SPST instantaneous contact switch, XMTR = ultrasonic transmitter 40-50kHz;
[0088] Ultrasonic receiver: Figure 10 This is a circuit diagram of an ultrasonic receiver provided according to an embodiment of this application, such as... Figure 10 The ultrasonic receiver parts list shown is as follows: RCVR = ultrasonic receiver 40-50kHz, RL1 = 6volt 200ohm resistor, IC2 = CA3140, VR2 = 250k variable resistor, R6 = 390k resistor, R7 = 470k resistor, R8, R12 = 15k resistor, R9 = 12k resistor, R10, R13 = 10k resistor, R11 = 4.7k resistor, R14 = 100k resistor, R15 = 33ohm resistor, C3 = 0.22uf ceramic capacitor, C4 = 0.1uf ceramic capacitor, C5 = 560n ceramic capacitor, T3, T4 = BC548 NPN transistor, T5 = BC558 PNP transistor, T6 = SL100 NPN transistor, D3, D4, D5 = 1N4148 diode.
[0089] The ultrasonic transmitter uses a 555-based astable multivibrator. It oscillates at a frequency of 40-50 kHz. An ultrasonic transmitter transducer is used here to transmit ultrasonic waves very efficiently. The ultrasonic transmitter is powered by a single 9-volt PP3 battery. The ultrasonic receiver circuit uses an ultrasonic receiver transducer to sense the ultrasonic signal. It also uses a two-stage amplifier, a rectifier stage, and an inverting operational amplifier. The output of the operational amplifier is connected to a relay via a complementary relay driver stage. A 9-volt battery eliminator can be used in the ultrasonic receiver circuit if needed. When the ultrasonic transmitter's switch S1 is pressed, the ultrasonic transmitter generates ultrasonic waves. The sound is received by the ultrasonic receiver transducer. It converts this into an electrical change of the same frequency. These signals are amplified by transistors T3 and T4. The amplified signals are then rectified and filtered. The filtered DC voltage is supplied to the inverting pin of operational amplifier IC2.

[0090] The aforementioned ultrasonic sensor can be selected to detect reflected ultrasonic waves within a specified range. However, it is important to note that the energy of the input ultrasonic waves comes from the ultrasonic sensor's input conversion circuit. Therefore, to increase the detection distance and range, further calculations are needed to determine the required circuit parameters, such as the voltage, which in turn determines the power input. The sensitivity adjustment module of the ultrasonic sensor can be adjusted via a sliding switch. A low-noise motor provides the power to open and close the hinge. The microcontroller is responsible for the switching, logic processing, and signal conversion of the entire circuit. The transmission belt converts the motor power into the force that pulls the hinge.
[0091] It is worth noting that the POS device proposed in this application uses ultrasonic sensors to optimize the interaction experience between bank tellers and customers, and improve the automation level of counter operations. Ultrasonic sensors can perform multiple measurements per second, have high sensitivity, are inexpensive, have controllable costs, are resistant to electromagnetic interference, and are suitable for noisy or other interference environments in bank branches. They also have low error. Furthermore, ultrasonic sensors can be replaced with infrared sensors. Infrared sensors have the ability to specifically identify human bodies, avoiding accidental opening and closing caused by objects passing by. In addition, infrared sensors are more concealed, smaller in size, and contribute to the aesthetics of the counter area.
[0092] The cash register device proposed in this application aims to optimize the business experience for both customers and tellers, and to solve the pain points in the interaction between bank counter service personnel and customers during the business process. It overcomes the problem of manual operation by customers in traditional counter cash registers, thus improving the customer experience and providing a counter cash register usage method that eliminates direct contact. The designed ultrasonic sensor circuit allows for adjustable sensitivity and delay settings, enabling corresponding changes according to different business scenarios.
