Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
In the related art, it is mainly detected whether the cashbox is in a closed state or a pop-up state by configuring a position detection switch at a side surface or a rear surface of the cashbox, thereby increasing the cost and complexity of the cashbox. Meanwhile, the service life of the position detection switch limits the wide application of the existing cashbox state detection mode to a certain extent.
In addition, in practical applications, a large number of existing cashboxes on the market currently are not provided with position detection switches, and for the cashboxes without the position detection switches, the detection of the cashbox ejecting state cannot be carried out by adopting the existing cashbox state detection method.
Therefore, the embodiment of the application provides a cashbox state detection method and device, electronic equipment and a storage medium.
In a first aspect, a cashbox status detecting method provided by an embodiment of the present application is first explained in detail.
As shown in fig. 2, a flowchart of steps of a cashbox status detecting method provided in an embodiment of the present application may specifically include the following steps:
s210, a drive current value of the drive coil in the cashbox is acquired.
Wherein the driving current value of the driving coil is changed during the money box is ejected.
Specifically, in the process of implementing the embodiment of the present application, the inventors found that: the driving coil in the existing cashbox is internally provided with a movable bolt which can be a movable iron core. In the process of ejecting the cashbox, the movable lock tongue moves, so that the driving current value of the driving coil in the cashbox can be changed.
The change characteristic of the drive current of the drive coil in the cashbox is similar to the change characteristic of the current generated by applying direct current to the inductor, but the current value passing through the inductor is different from the current value constantly rising after applying direct current to the inductor. Because the movable lock tongue is arranged in the driving coil in the cashbox, certain back electromotive force can be generated on the driving coil after the lock tongue is pulled, and a valley section appears in the rising process of the driving current. Therefore, the cashbox ejection detection can be carried out by utilizing the change characteristics of the driving current of the driving coil in the cashbox, a position detection switch does not need to be configured in the cashbox, and the cashbox ejection detection method is compatible with almost all cashboxes on the market.
In one embodiment, obtaining the driving current values of the driving coils in the cashbox may include the following steps, step a1 and step a 2:
step a1, a value of current through the current sampling resistor is determined.
The current sampling resistor is a resistor connected in series in a cashbox driving circuit of the cashbox control equipment.
Step a2, the value of the current passing through the current sampling resistor is determined as the value of the drive current of the drive coil in the cashbox.
In this embodiment, a current sampling resistor may be connected in series in the cashbox drive circuit of the cashbox control apparatus in order to accurately collect the drive current value through the drive coil in the cashbox. It will be appreciated that the value of the current through the current sampling resistor is the value of the drive current through the drive coil in the cashbox.
In practical application, the current value passing through the current sampling resistor can be obtained by measuring the voltage at the two ends of the current sampling resistor and dividing the voltage at the two ends of the current sampling resistor by the current sampling resistor, and the current value passing through the current sampling resistor is determined as the driving current value of the driving coil in the cashbox. Thereby achieving a drive current value to the drive coil in the cashbox.
It should be noted that for the sake of completeness and clarity of the description of the scheme, the following embodiments will explain in detail the process of changing the driving current value of the driving coil of the cashbox during the process of ejecting the cashbox.
And S220, judging that the state of the cashbox is an ejecting state when the driving current value is the target current value.
Wherein the target current value is a minimum current value of the driving current values.
Specifically, because the movable lock tongue is arranged in the driving coil in the cashbox, in the process of popping the cashbox, the lock tongue can generate certain back electromotive force on the driving coil after being pulled, and a valley section appears in the rising process of the driving current. Therefore, after the drive current value of the drive coil in the cashbox is acquired, when it is detected that the drive current value reaches a low valley, that is, a minimum current value, it is possible to judge that the state of the cashbox is the pop-up state.
According to the technical scheme, when the cashbox state is detected, the driving current value of the driving coil in the cashbox is obtained, and the popping state of the cashbox is judged by detecting the valley of the driving current value by utilizing the change characteristic of the driving current value of the driving coil in the popping process of the cashbox. It can be seen that through the technical scheme provided by the embodiment of the application, when the pop-up state of the cashbox is detected, a position detection switch is not required to be configured in the cashbox, so that the cost and the structural complexity of the cashbox are saved, and the detection mode is compatible with almost all cashboxes on the market.
For completeness of the scheme and clarity of description of the scheme, the process of changing the driving current value of the driving coil of the cashbox during the cashbox is ejected will be explained in detail in the following embodiments.
In one embodiment, the process of changing the drive current value of the drive coil during ejection of the cashbox, as shown in fig. 3, may include the following:
in the first period, the driving current value of the driving coil is gradually increased S310.
And in the first time period, the movable bolt in the driving coil does not move.
Specifically, during the first time period T1, the cashbox controlling device has just applied a driving voltage to the cashbox, the movable latch in the driving coil does not move, and at this time, the driving coil is equivalent to an inductor, so that the driving current value of the driving coil gradually increases after the cashbox controlling device applies a voltage to the driving coil.
And S320, gradually increasing the driving current value of the driving coil in a second time period.
And in the second time period, the movable bolt in the driving coil moves in the driving coil, and in the second time period, the increasing speed of the driving current value is smaller than that in the first time period.
Specifically, during the second time period T2, the movable bolt in the driving coil starts to move in the driving coil, and during the movement, there is frictional resistance between the movable bolt and the driving coil, and the driving coil applies work to the movable bolt, so the driving current value of the driving coil in the second time period T2 increases at a rate that is less than the rate of the increase of the driving current value in the first time period T1.
S330, the driving current value of the driving coil is gradually decreased in the third period.
And in the third time period, the movable bolt in the driving coil moves outside the driving coil.
Specifically, in a third time period T3, the movable bolt is separated from the driving coil, there is no frictional resistance between the movable bolt and the driving coil, the acceleration of the movable bolt increases, the magnetic potential energy is converted into the kinetic energy of the movable bolt, the driving current value of the driving coil gradually decreases until the movable bolt stops moving, the driving current value of the driving coil decreases to the minimum, and at this time, the cashbox is in the pop-up state.
And S340, gradually increasing the driving current value of the driving coil in a fourth time period until the driving current value of the driving coil is increased to the maximum value.
And in the fourth time period, the movable bolt in the driving coil stops moving.
Specifically, in the fourth time period T4, after the movable bolt stops moving, the driving coil is equivalent to an inductor again, and the driving current value of the driving coil gradually increases until the driving current value of the driving coil increases to the internal resistance current-limiting value of the driving coil.
As shown in fig. 4, the driving current values of the driving coils in four periods, i.e., the first period T1, the first period T2, the third period T3 and the fourth period T4, are schematically changed. In fig. 4, the horizontal axis is used to represent time, and the vertical axis is used to represent the magnitude of the current value, in practical applications, the unit of time and the unit of the current value may be determined according to practical situations, which is not specifically limited in this embodiment of the present application. Fig. 4 is used only to describe the variation tendency of the drive current values of the drive coils in four periods.
Therefore, by the technical scheme provided by the embodiment of the application, the change situation of the driving current value of the driving coil in the cashbox popping process can be accurately acquired, and the cashbox popping state can be judged by detecting the valley of the driving current value.
On the basis of the above embodiment, after the cashbox is detected to be in the ejection state, in order to reduce the generation of additional heat of the driving coil caused by the continuous application of the driving voltage by the driving coil, the service life and the reliability of the driving coil are reduced. In one embodiment, when the driving current value is the target current value, the cashbox state detecting method may further include:
the driving voltage value of the cashbox driving circuit is reduced.
In this embodiment, when the driving current value is the target current value, indicating that the cashbox is in the pop-up state has been detected, in order to reduce the generation of a large amount of additional heat by the driving coil, the driving voltage value of the cashbox driving circuit may be reduced, and thus, the driving voltage value applied to the driving coil of the cashbox is also reduced. In practical application, the driving voltage value of the cashbox driving circuit can be reduced to 0.
Therefore, according to the technical scheme provided by the embodiment, after the cashbox is detected to be in the popping state, the driving voltage value of the cashbox driving circuit is reduced, a large amount of extra heat generated by the driving coil can be reduced, the service life of the driving coil can be prolonged, and the reliability of the driving coil is improved. In addition, the cashbox driving power occupies a higher proportion in the system input power, and the stability of the system is reduced due to the overlong driving time, so that the stability of the system can be improved by reducing the driving voltage value of the cashbox driving circuit.
On the basis of the above-described embodiment, if a variation in the drive current value of the drive coil does not conform to a variation law of the first period, the second period, the third period, and the fourth period during the money box being ejected, the money box state detecting method may further include the steps of:
a fault is determined in the process of ejecting the cashbox.
In this embodiment, if the variation of the driving current value of the driving coil does not conform to the variation rule of the first time period, the second time period, the third time period and the fourth time period during the ejection of the cashbox, it indicates that the cashbox is out of order during the ejection, such as the cashbox is jammed. And the fault can be reported, so that the work personnel can repair the cashbox in time, and the cashbox can be recovered to a normal working state.
It can be seen that through the technical scheme that this embodiment provided, through monitoring cashbox pop-up in-process, the change situation of the drive current value of drive coil is favorable to realizing cashbox fault detection.
For clarity of description of the scheme, the cashbox status detecting method of the embodiment of the application will be explained in detail with reference to specific examples.
As shown in fig. 5, a schematic diagram of the cashbox and cashbox control apparatus is shown.
As can be seen from fig. 5, the cashbox is connected to the cashbox control device by a cashbox connecting line. The cashbox control device is provided with a driving circuit, and the processor applies cashbox control signals to the driving circuit; and, realize current collection through connecting a current sampling resistance (not shown in fig. 5) in series in the drive circuit, namely gather the drive current value of the drive coil (not shown in fig. 5) in the cashbox, and carry out the valley detection to the drive current value, when detecting that the drive current value is in the valley, the treater judges that the cashbox is in the pop-up state, at this moment, the treater can change cashbox control signal, namely fall the drive voltage value of drive circuit to 0, in order to avoid the cashbox drive coil to produce extra heat.
Therefore, according to the technical scheme provided by the embodiment of the application, under the condition that an additional position detection switch is not configured for the cashbox, the detection of the popup state of the cashbox can be realized by utilizing the characteristic of change of the driving current of the driving coil of the cashbox. Therefore, the cost and the structural complexity of the cashbox are saved, and the detection mode is compatible with almost all cashboxes on the market.
