Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
As shown in fig. 1, in an embodiment, a method for controlling a diverter is provided, and an execution subject of the method for controlling a diverter according to the embodiment of the present invention is a device capable of implementing the method for controlling a diverter according to the embodiment of the present invention, where the device may include, but is not limited to, a financial self-service device including, but not limited to, a cash dispenser and a cash self-service access device, and the financial self-service device includes a banknote transmission channel, a physical sensor, a virtual sensor and a control unit, where the physical sensor is disposed in the banknote transmission channel. The banknote transmission channel refers to a channel for passing and transmitting banknotes in the financial self-service equipment. The control method of the commutator specifically comprises the following steps:
and 102, when the physical sensor detects that the paper currency passes through, the control unit determines a transmission path of the paper currency.
The physical sensor, which may include but is not limited to a photoelectric sensor, is used to detect whether a banknote passes through, so that when it is determined that a banknote passes through, the current position of the banknote can be determined according to the position of the physical sensor in the banknote transmission channel. The signal detected by the photoelectric sensor is different between the passage of a banknote and the passage of no banknote, for example, the optical signal detected by the photoelectric sensor is interrupted when a banknote passes, thereby determining the passage of a banknote.
The transmission path is a path for transmitting the paper money in the financial self-service equipment, and is shown in fig. 2, for example. For example, storage spaces for bills of different amounts are provided in the financial self-service device, and therefore, in order to deposit bills of different amounts into different storage spaces, it is necessary to determine a transport path for bills of different amounts. For example, a 100 yuan bill corresponds to a transport path a, and a 50 yuan bill corresponds to a transport path B; for another example, the transmission path corresponding to the RMB is C, and the transmission path corresponding to the yen is D.
And 104, the control unit determines the positions of a target reverser corresponding to the conveying path and a target virtual sensor corresponding to the conveying path in the paper money conveying channel, wherein the positions are determined according to the conveying speed of the paper money in the paper money conveying channel, the distance between the physical sensor and the target reverser and the switching time consumption of the target reverser.
The target diverter is a diverter which needs to perform a diverting operation after the paper money passes through the physical sensor, so as to divert the paper money, for example, as shown in fig. 2, the physical sensor detects that the paper money enters, but not all diverters need to perform the diverting operation, but the corresponding diverter is controlled to perform the diverting operation according to the transmission path of the paper money, for example, the diverter corresponding to the path C is the target diverter, and the diverter corresponding to the path C is controlled to perform the diverting operation; for another example, the commutator corresponding to the path E is the target commutator, and the commutator corresponding to the path E is controlled to perform the commutation operation.
The target virtual sensor is arranged beside the target commutator, and specifically, when the target virtual sensor is triggered, the control unit generates a commutation command and sends the commutation command to the commutator, so that the commutator executes a commutation operation.
The virtual sensor may be disposed on the banknote transportation path, specifically, as shown in fig. 3, a virtual sensor is disposed near each diverter and near the physical sensor to control the corresponding diverter to divert by the virtual sensor, and the specific position of the virtual sensor may be determined according to the banknote transportation speed, the distance between the physical sensor and the target diverter, and the switching time. The position of the virtual sensor is important, and if the position of the virtual sensor is arranged in a mess, the commutation failure of the commutator can be caused. The embodiment of the invention fully considers the paper money transmission speed, the distance between the physical sensor and the target reverser and the switching time consumption to determine the position of the virtual sensor in the paper money transmission channel, thereby improving the reversing success rate of the reverser.
Different paper money and different financial self-service equipment can cause different transmission speeds of the paper money in the paper money transmission channel, so that the reverser needs to be controlled to change the direction according to the transmission speed of the paper money in the paper money transmission channel; as shown in fig. 2, the distance between the physical sensor and the target diverter is the length of the paper money transmission channel from the physical sensor to the target diverter; when the switching is time-consuming, the target commutator is the time from starting to executing the commutation task to finishing (i.e. completing the commutation).
And 106, when the position of the paper currency in the paper currency conveying channel through the target virtual sensor is detected, controlling the target reverser to execute reversing operation by the control unit.
When the target virtual sensor is triggered, namely the paper money is considered to pass through the position of the target virtual sensor in the paper money transmission channel, the target reverser is controlled to execute reversing operation, and the reversing time of the target reverser is accurately controlled.
The control method of the reverser is applied to financial self-service equipment comprising a paper money transmission channel, a physical sensor, a virtual sensor and a control unit, wherein the physical sensor is arranged in the paper money transmission channel; the method comprises the following steps: when the physical sensor detects that paper currency passes through, the control unit determines a transmission path of the paper currency; the control unit determines the positions of a target reverser corresponding to the conveying path and a target virtual sensor corresponding to the conveying path in the paper money conveying channel, wherein the positions are determined according to the conveying speed of the paper money in the paper money conveying channel, the distance between the physical sensor and the target reverser and the switching time consumption of the target reverser; when the position of the paper money in the paper money transmission channel through the target virtual sensor is detected, the control unit controls the target reverser to execute reversing operation. Therefore, due to the fact that the virtual sensor is arranged and the position of the virtual sensor is determined according to the paper money transmission speed, the distance between the physical sensor and the target reverser and the switching time consumption of the target reverser, the target reverser is controlled to be switched when the virtual sensor is triggered, a certain time is reserved for the target reverser to successfully execute reversing operation, and the switching success rate is improved.
In one embodiment, as shown in FIG. 4, a method of controlling a commutator is provided that illustrates how the position of a virtual sensor is determined. The control method of the commutator comprises the following steps:
The switching distance is a distance between the virtual sensor M and the target commutator, and as shown in fig. 3, the switching distance between the virtual sensor M and the target commutator is s. By reserving a certain switching distance, the target reverser is controlled to switch when the virtual sensor M is triggered, so that the target reverser can be ensured to be successfully reversed when the paper money is transmitted to the target reverser from the virtual sensor M. For example, if the transport speed of the banknote in the banknote transport channel is v and the switching time of the target diverter is t, the switching distance is v × t.
The triggering distance is a distance between the physical sensor and the target commutator, for example, as shown in fig. 3, assuming that the second commutator closest to the physical sensor is the target commutator, the distance between the physical sensor and the target commutator is l.
And 406, determining the position of the target virtual sensor in the paper money transmission channel according to the difference between the trigger distance and the switching distance.
As shown in fig. 3, the difference between the trigger distance and the switching distance is first calculated: l-s, the distance between the virtual sensor M and the physical sensor can be determined according to the difference l-s between the trigger distance and the switching distance, so that the position of the virtual sensor in the paper money transmission channel is determined, for example, the position of the physical sensor is taken as the origin of coordinates, and the coordinate position of the target virtual sensor can be obtained according to the difference between the trigger distance and the switching distance.
In one embodiment, as shown in fig. 5, the target virtual sensor includes a rising edge and a falling edge, the virtual sensor is a non-physical sensor, i.e. the banknote transport path is not additionally provided with the virtual sensor, and the virtual sensor is arranged to indicate the position for controlling the target diverter to execute the diverting operation. As shown in fig. 6, the step 402 of determining a switching distance according to the transport speed of the banknote in the banknote transport channel and the switching time consumption of the target diverter includes:
For example, assuming that the transport speed of the bill in the bill transport path is v and the switching time of the target diverter is t, the distance s1 between the falling edge of the virtual sensor and the target diverter is v × t.
For example, the distance s1 between the falling edge of the virtual sensor and the target commutator is v × t, and the distance s2 between the rising edge of the virtual sensor and the target commutator is 2 × v × t.
Assuming that the distance between the rising edge of the target virtual sensor and the target commutator is a switching distance s3, s3 is s 2.
In one embodiment, the control unit comprises a main control unit and a micro control unit, wherein the main control unit and the micro control unit respectively execute different control operations, and the division of labor is clear, so that the main control unit can perform overall control in a good state; as shown in fig. 7, the method further comprises:
and 706, the master controller acquires a commutator identifier of the target commutator and a micro-control identifier for controlling micro-control of the target commutator.
The commutator identifier is used for uniquely identifying one commutator; the micro-control identification is used for uniquely identifying one micro-control; and the micro controller is a microcontroller and comprises an MCU.
And a micro-control commutator comparison table is established in advance, the micro-control commutator comparison table records the corresponding relation between the micro-control identification and the commutator identification, and one micro-control corresponds to at least one commutator, so that the micro-control identification for controlling the reversing of the target commutator can be determined according to the micro-control commutator comparison table.
And 708, generating a control instruction according to the position of the diverter identifier, the micro-control identifier and the target virtual sensor in the paper money transmission channel.
Illustratively, table 1 is the control instructions generated.
TABLE 1
The action type includes write, read, on and off, and since the control command is generated and sent to the corresponding micro controller, the action type is 3 here, which represents writing data to the can bus.
Wherein, the data length indicates the occupied digit of the "data" part in the table, if only one digit is occupied, the data length is 1, for example, only D0 digits are occupied, and the corresponding data length is 1; if 2 bits are occupied, for example, D0 and D1 bits are occupied, the corresponding data length is 2.
S below D0 in table 1 indicates the position of the target virtual sensor in the banknote transport path, i.e., the distance of the target virtual sensor from the physical sensor.
After the micro-control receives the control instruction sent by the main control, whether the target virtual sensor is triggered or not is determined according to the position S of the target virtual sensor in the paper money transmission channel and the paper money transmission speed, redundant virtual sensors do not need to be additionally arranged, and cost is saved.
In one embodiment, a method of determining a target virtual sensor trigger is provided, the financial self-service device further comprising a timer; after the step 710 of sending the control instruction to the micro controller corresponding to the micro controller identifier, the method further includes: the micro control corresponding to the micro control identification determines the time for transmitting the paper money from the physical sensor to the target virtual sensor according to the position of the target virtual sensor in the paper money transmission channel and the transmission speed of the paper money in the paper money transmission channel; the micro control corresponding to the micro control identification sends a timing instruction determined according to the time of the paper money transmitted from the physical sensor to the target virtual sensor to the timer so that the timer starts timing; when the timer counts the time of the paper money transmitted from the physical sensor to the target virtual sensor, the micro-control corresponding to the micro-control identification determines the triggering of the target virtual sensor.
For example, assuming that the position of the target virtual sensor in the paper money transmission channel is S and the transmission speed of the paper money is v, the time S/v for the paper money to be transmitted from the physical sensor to the target virtual sensor is S/v; controlling a timer to time according to the S/v; and when the timing reaches the time S/v, the target virtual sensor triggers.
In one embodiment, a method of determining target virtual sensor triggering is provided, the financial self-service device further comprising a stepper motor; after the step 710 of sending the control instruction to the micro controller corresponding to the micro controller identifier, the method further includes: the micro control corresponding to the micro control identification determines the target stepping step number of the stepping motor according to the position of the target virtual sensor in the paper money transmission channel; and when the stepping step number of the stepping motor reaches the target stepping step number, the micro control corresponding to the micro control identification determines the triggering of the target virtual sensor.
And when the number of steps taken by the stepping motor reaches the target stepping number, the target virtual sensor is considered to be triggered.
For example, assuming that the stepping motor steps by a distance corresponding to S1 and the position of the target virtual sensor in the bill conveying path is S, the target number of stepping steps is S/S1.
Accordingly, the step 712 of controlling the target diverter to perform the diverting operation when the position of the bill in the bill transfer path through the target virtual sensor is detected includes: and when the position of the paper money in the paper money transmission channel through the target virtual sensor is detected, the micro-control corresponding to the micro-control identification controls the target reverser to execute reversing operation.
In one embodiment, in order to achieve feedback of the execution result, specifically, after the controlling unit controls the target commutator to perform the commutation operation in step 712, the method further includes:
and the master control acquires an execution result corresponding to the reversing operation returned by the micro control corresponding to the micro control identification.
And the micro-control acquires an execution result of the reversing operation of the target reverser (the reversing is successful or the reversing is failed), and then the execution result of the reversing operation is sent to the main control, so that the main control can fully know the reversing result, and if the reversing is failed, workers can be required to overhaul the financial self-service equipment.
Illustratively, the micro-controller returns the execution results to the master via table 2.
TABLE 2
Err is the execution result, and when the execution result is that the commutation is successful, Err is 0; when the execution result is a commutation failure, Err is not 0, and Err values are different according to failure reasons, for example, if the error factor is ABC, Err is 1, and if the error factor is BCD, Err is 2.
