Fig. 1 shows a method for detecting a residual stacked banknote in a banknote deposit and withdrawal port according to an embodiment of the present invention, which includes the following steps:

step 101: starting a plurality of static sensors distributed in a cash deposit and withdrawal port of the customer receiving part for detecting whether residual paper money exists in the cash deposit and withdrawal port, wherein a guide plate 20, a separation plate 40 and a push plate 30 arranged between the guide plate 20 and the separation plate 40 are arranged in the cash deposit and withdrawal port;

step 102: if any one of the plurality of static sensors is in a state of 1, starting a push plate moving mechanism to control the push plate 30 to move to a separation limit position, namely, controlling the push plate 30 to move towards the position of the separation plate 40;

step 103: starting a money digging wheel sensor PI207 and a push plate position sensor PI 206; the push plate position sensor PI206 is used for detecting whether the push plate moves to a separation limit position;

step 104: if the state of the push plate position sensor PI206 is 0, the push plate 30 fails to be in place, and the state of the banknote digging wheel sensor PI207 is 1, residual banknotes exist between the push plate 30 and the separating plate 40;

step 105: the state of the push plate position sensor PI206 is 1, the push plate 30 is successfully in place, no residual paper money exists between the push plate 30 and the separating plate 40, and the stacked residual paper money is determined to be between the push plate 30 and the guide plate 20;

As shown in fig. 2, the method of the embodiment of the present invention operates as follows: the method comprises the following steps that a plurality of static sensors carry out correlation detection, when the static sensors are shielded, the state of the shielded static sensors is 1, the state of any one static sensor is 1, and the stack is considered to have residues; otherwise, no residue is left.

When the detection result shows that the residual paper money exists, the position of the residual paper money on the customer receiving part needs to be detected, and the push plate 30 is controlled to move to the separation limit position A, so that two situations can occur.

Case 1: if the push plate 30 fails in place and the banknote digging wheel sensor PI207 is shielded, it can be shown that residual banknotes exist between the push plate and the separation plate 40, but whether residual banknotes exist between the push plate 30 and the guide plate 20 is unknown, and the residual banknotes are determined after later control but the residual state is present;

case 2: if the push plate 30 is successfully positioned at the separation limit position A, it is indicated that there is no residual paper money between the push plate 30 and the separation plate 40, and it can be inferred that the stack is left between the push plate 30 and the guide plate 20 and the residual state is present.

According to the method provided by the embodiment of the invention, whether the paper money is left in the money access port can be reliably determined according to the detection results of the static sensor, the paper money digging wheel sensor PI207 and the push plate position sensor PI206 and the preset algorithm, and whether the residual paper money exists between the push plate 30 and the separating plate 40 or not can be further determined under the condition of confirming the residual paper money, and whether the stacked residual paper money exists between the push plate 30 and the guide plate 20 or not can be further determined, so that the control trouble or unnecessary control fault brought in the transaction can be effectively avoided.

In one embodiment, the method further comprises:

if the push plate 30 fails to be in place, starting a banknote sorting mechanism for detecting whether banknotes exist between the push plate 30 and the separating plate 40 or not, controlling the banknotes between the push plate 30 and the separating plate 40 to be sorted, and determining whether the banknotes remain between the push plate 30 and the separating plate 40 in the banknote sorting process according to the state of the banknote digging wheel sensor PI 207; or

Referring to fig. 3, in the cash receiving and dispensing port transaction control, a detection signal of the receiving and depositing sensor disposed in the cash receiving channel 51 is received, whether there is a paper money between the push plate 30 and the guide plate 20 is determined according to the detection signal, and if the receiving and depositing sensor detects that a paper money passes through, it is determined that there is a residue between the push plate 30 and the guide plate 20 when the status of any one of the plurality of static sensors is 1.

Specifically, the banknote sorting mechanism is started, whether the banknotes exist between the push plate 30 and the separating plate 40 or not is detected, the banknotes between the push plate 30 and the separating plate 40 are controlled to be sorted, and whether the stacks have residues or not is detected in the banknote sorting process;

if no residue exists, the residual state of the paper money at the money storing and taking port is zero;

if the residual paper money exists, a deposit sensor arranged on the paper money distribution channel 52 is started to detect the paper money, and if the paper money cannot be shielded in the set time of the deposit sensor, no residual paper money possibly exists between the push plate 30 and the separating plate 40; and starting the push plate moving mechanism to continuously move the push plate 30 to the separation limit position A towards the separation plate 40, wherein the push plate 30 is successfully positioned, no residue is left between the push plate 30 and the separation plate 40, and paper money residues are left between the push plate and the guide plate 20.

In case 1, when the push plate fails to be in place and the banknote digging wheel sensor PI207 is shielded, it is unknown whether residual banknotes exist between the push plate 30 and the guide plate 20; the embodiment of the invention further detects and determines the condition 1, continuously pushes the push plate 30 to move to the separation limit position A, and effectively determines whether residual paper money exists between the push plate 30 and the guide plate 20 according to the detection result of the deposit sensor and a preset algorithm.

In one embodiment, the method further comprises: when the push plate fails to be in place and the money is controlled by the transaction at the money receiving and dispensing port, the detection signal of the receiving and storing sensor arranged in the money receiving channel 51 is received, whether paper money exists between the push plate 30 and the guide plate 20 is judged according to the detection signal, for example, the receiving and storing sensor SC220 and the receiving and storing sensor SC221 detect whether the paper money passes through the triggering of the receiving part, and the state of any one of the plurality of static sensors is 1, so that the fact that the residue exists between the push plate 30 and the guide plate 20 is determined.

According to the method provided by the embodiment of the invention, whether residual paper money exists between the push plate 30 and the guide plate 20 can be quickly and reliably determined according to the detection results of the receiving and storing sensor and the static sensor and the preset algorithm when the transaction money receiving control is carried out at the money receiving and storing port.

In one embodiment, the plurality of static sensors of the front panel of the start receiver includes a first stacking residue sensor disposed at an upper portion of the banknote deposit and a second stacking residue sensor, such as the opposed static sensor SC205 and the static sensor SC206, disposed at a lower portion of the banknote deposit and withdrawal, and the second stacking residue sensor, such as the opposed static sensor SC207, the static sensor SC208, the static sensor SC209, and the static sensor SC 210.

In one embodiment, the deposit sensors disposed in the banknote distribution passage 52 include a first deposit sensor and a second deposit sensor disposed along the length and width directions of the banknote, respectively, and determine that there is no residual banknote between the push plate 30 and the separation plate 40 when the first deposit sensor and the second deposit sensor do not detect the banknote obstruction within a set time. In specific implementation, the first credit sensor and the second credit sensor are a sensor combination. For example, the first credit sensor combination is a combination of a first credit sensor, a third credit sensor and a fourth credit sensor. The second credit sensor combination is a combination of a second credit sensor, a fourth credit sensor and a fifth credit sensor. The first to fifth deposit sensors are arranged in a combination relationship to detect the length and width of the bill by the combination of the deposit sensors, respectively, thereby determining whether the bill is present. The details of how to detect the length and width of the paper money are not described herein. In the present embodiment, the first deposit sensor SC216, the second deposit sensor SC217, the third deposit sensor SC218, the fourth deposit sensor SC223, the fifth deposit sensor SC224 are activated; when the combination of the first deposit sensor SC216, the third deposit sensor SC218, and the fourth deposit sensor SC223 and the combination of the second deposit sensor SC217, the fourth deposit sensor SC223, and the fifth deposit sensor SC224 do not detect the blocking of the banknotes within a set time, it is determined that there may be no remaining banknotes between the push plate 30 and the separation plate 40.

If the push plate fails to be in place and the PI207 is shielded, the situation that residual paper money exists between the push plate 30 and the separating plate 40 can be shown, but whether residual paper money exists between the push plate 30 and the guide plate 20 is unknown, and the situation is determined by later control, but the residual state is present; the detection is carried out when the money-sorting transaction is carried out at the money-storing port. The paper money between the push plate 30 and the separating plate 40 is controlled to be divided firstly, and the process detects whether the stack has residues or not. If no residue exists, the residual state of the money storing and taking port is zero; on the contrary, the method according to the embodiment of the invention uses the combined detection results of the first deposit sensor SC216, the second deposit sensor SC217, the third deposit sensor SC218, the fourth deposit sensor SC223 and the fifth deposit sensor SC224 arranged in the banknote sorting channel 52 and the preset algorithm to determine that there may be no residual banknotes between the push plate 30 and the separation plate 40, so as to prepare for further determining the banknote residual situation between the push plate 30 and the separation plate 40.

Referring to fig. 4, an embodiment of the present invention further provides a device for detecting a banknote stack residue at a banknote taking port, which is used to implement the above method, and the device includes:

the static starting unit 50 is used for starting a plurality of static sensors distributed at the money receiving and storing port of the customer receiving part to detect the residual state of the paper money at the money receiving and storing port;

the dynamic starting unit 60 is used for starting the banknote digging wheel sensor PI207 and the push plate position sensor PI206, and is used for starting the push plate movement mechanism to control the push plate 30 to move to the separation limit position a towards the direction of the separation plate 40 when the state of any one of the plurality of static sensors is 1;

wherein the dynamic boot unit comprises a first determining unit 61, a second determining unit 62, a first determining unit 63, a first determining unit 64, a first determining unit 65 and a second determining unit 66.

The second determining unit is used for determining that no residual paper money exists between the push plate 30 and the separating plate 40 and stacked residual paper money is between the push plate 30 and the guide plate 20 when the push plate position sensor PI206 is in a state of 1 and the push plate is successfully in place.

The third determining unit is used for starting the banknote sorting mechanism when the push plate 30 fails to be in place, detecting whether banknotes exist between the push plate 30 and the separating plate 40, controlling the banknotes between the push plate 30 and the separating plate 40 to be sorted, and determining whether banknotes remain between the push plate 30 and the separating plate 40 in the banknote sorting process according to the state of the banknote digging wheel sensor PI 207.

The fifth determining unit is configured to, during the banknote sorting process, start the deposit sensor disposed in the banknote sorting channel 52 to detect the banknote if the status of any one of the plurality of static sensors is 1 and the status of the banknote digging wheel sensor PI207 is 0, and further start the push plate moving mechanism to continue to push the push plate 30 to move to the separation limit position a in the direction toward the separation plate 40 if the banknote blocking cannot be detected within the set time of the deposit sensor, and when the push plate 30 is successfully located, determine that no residue exists between the push plate 30 and the separation plate 40, and that there is a banknote residue between the push plate 30 and the guide plate 20.

The sixth determination unit is configured to determine that there is no residual banknote between the push plate 30 and the separation plate 40 when the first deposit sensor and the second deposit sensor detect no banknote blocking within a set time, for example, in an embodiment, when a combination of the first deposit sensor SC216, the third deposit sensor SC218, and the fourth deposit sensor SC223 and a combination of the second deposit sensor SC217, the fourth deposit sensor SC223, and the fifth deposit sensor SC224 detect no banknote blocking within a set time.

The working principle of the device of the embodiment of the invention is as follows: the static starting unit starts a plurality of static sensors to perform correlation light detection, when the static sensors are shielded, the state of the shielded static sensors is 1, the state of any one static sensor is 1, and the static starting unit 50 determines that paper money residues are stacked; otherwise, no residue is left.

If the detection result is that the paper money is remained and the position of the remained paper money needs to be detected, the dynamic starting unit starts the push plate moving mechanism to control the push plate 30 to move towards the direction of the separating plate 40 to the separating limit position A, and two situations can occur. The dynamic starting unit 60 starts the banknote digging wheel sensor PI207, and the dynamic starting unit 60 starts the push plate position sensor PI206 to detect the position state of the push plate 30.

Case 1: if the push plate 30 fails to be in place and the banknote digging wheel sensor PI207 is shielded, the second determination unit determines that residual banknotes exist between the push plate 30 and the separation plate 40;

case 2: if the push plate 30 is successfully positioned at the separation limit position, which indicates that there is no residual paper money between the push plate 30 and the separation plate 40, the second determination unit determines that the stack remains between the push plate 30 and the guide plate 20 and the residual state is present.

Preferably, the banknote digging wheel sensor PI207 is an off-circuit sensor.

In case 1, when the push plate 30 fails to reach the position and the banknote digging wheel sensor PI207 is shielded, it is unknown whether residual banknotes exist between the push plate 30 and the guide plate 20; the embodiment of the invention further detects and determines the condition 1, continues to push the push plate 30 to move to the separation limit position A, and determines whether residual paper money exists between the push plate 30 and the guide plate 20 according to the detection result of the deposit sensor and a preset algorithm.

The fourth determining unit is configured to receive a detection signal of a customer receiving and storing sensor disposed in the banknote receiving channel during the transaction banknote receiving control at the banknote receiving and storing port when the push plate fails to be in place, and determine whether there is a banknote in the push plate 30 and the guide plate 20 according to the detection signal. If the customer reception sensor detects the passage of the bill, it is determined that there is a residue between the push plate 30 and the guide plate 20 when the state of any one of the plurality of static sensors is 1.

In the embodiment of the present invention, during the cash transaction control at the cash deposit/withdrawal port, the fourth determining unit receives the detection signals of the deposit/reception sensor, such as the deposit/reception sensor SC220 and the deposit/reception sensor SC221, and detects that the deposit/reception sensor SC220 and the deposit/reception sensor SC221 have the triggered passage of the banknotes. If the customer deposit sensor detects the passage of a bill and the opposed static sensors SC205 and SC206 and the opposed static sensors SC207, SC208, SC209 and SC210 detect the stacking of bills, the fourth determination unit determines that there is a bill remaining between the pusher 30 and the guide plate 20.

In one embodiment, the plurality of static sensors are divided into a first stacking residue sensor, such as the opposed static sensor SC205 and the static sensor SC206, disposed at the upper part of the banknote deposit and withdrawal port, and a second stacking residue sensor, such as the opposed static sensor SC207, the static sensor SC208, the static sensor SC209 and the static sensor SC210, disposed at the lower part of the banknote deposit and withdrawal port. In the embodiment of the present invention, the static sensors are all correlation sensors, and the first stacking residual sensor is a correlation static sensor SC205 and a correlation static sensor SC 206. The second stacking residue sensors are a static sensor SC207, a static sensor SC208, a static sensor SC209, and a static sensor SC210, which are opposed to each other, and the static start unit 50 determines that there is a residual banknote when any of the sensors is in the state of 1.

In one embodiment, the deposit sensors disposed in the dispensing passage 52 include a first deposit sensor and a second deposit sensor disposed along the length and width directions of the banknotes, respectively. When the first deposit sensor and the second deposit sensor do not detect the blocking of the paper money within a set time, it is determined that there is no residual paper money between the push plate 30 and the separation plate 40. In specific implementation, the first credit sensor and the second credit sensor are a sensor combination. For example, in the embodiment, the first deposit sensor SC216, the third deposit sensor SC218, and the fourth deposit sensor SC223 are used as a combination of the first deposit sensors, and the second deposit sensor SC217, the fourth deposit sensor SC223, and the fifth deposit sensor SC224 are used as a combination of the second deposit sensors.

As can be seen from the above description, implementing the embodiments of the present invention has the following beneficial effects:

when the embodiment of the invention is applied to the receiving part with the guide plate 20, the push plate 30 and the separating plate 40, the position of the residual paper money in the stack can be determined according to the detection results of the static sensor, the push plate position sensor PI206 and the paper money digging wheel sensor PI207 and a preset algorithm, the position interval of the residual paper money stack in the receiving part of the money access opening can be effectively detected and judged, the control trouble or unnecessary control fault caused in the transaction can be avoided, and important control basis is provided for whether the lifting platform of the money opening door is lifted, the paper money recovery control, the customer position positioning control of the receiving baffle and the overtime detection of the paper money in the receiving part.
