At present, the control device provided in the related art has poor stability, which affects the use of the storage device and causes poor user experience to a certain extent.
For the understanding of the present embodiment, a detailed description will be given to a control circuit disclosed in the embodiment of the present invention.
The invention provides a control circuit which comprises a controller, a main driving circuit and a first power supply. Wherein the controller comprises a signal output end; the signal output end is electrically connected with one end of the main driving circuit, the other end of the main driving circuit is electrically connected with a first pin of the storage structure, and the first power supply is electrically connected with a second pin of the storage structure; the controller is used for sending a driving signal to the main driving circuit through the signal output end; the main driving circuit is used for receiving a driving signal and applying a first specified voltage to the first pin; the first power supply is used for applying a second specified voltage to the second pin to generate a voltage difference between the first pin and the second pin so as to drive the storage structure to be opened.
For convenience of understanding, fig. 1 illustrates a structural schematic diagram of a control circuit, and as shown in fig. 1, the control circuit includes a controller 110, a main driving circuit 120 and a first power supply 130, the controller 110 includes a signal output end 111, the signal output end 111 is electrically connected to one end of the main driving circuit 120, the other end of the main driving circuit 120 is electrically connected to a first pin of the storage structure, and the first power supply 130 is electrically connected to a second pin of the storage structure. Illustratively, the storage structure may be a money box or the like.
In one embodiment, the controller 110 sends a driving signal to the main driving circuit 120 through the signal output terminal 111, and the driving signal is used for controlling the main driving circuit 120 to apply a first designated voltage to the first pin. After receiving the driving signal, the main driving circuit 120 may apply a first specified voltage to the first pin of the storage structure, and in addition, the first power source 130 continuously applies a specified voltage to the second pin of the storage structure, where the second specified voltage may be 24V, and the first specified voltage is different from the first specified voltage, so as to generate a voltage difference between the first pin and the second pin of the storage structure, where a driving coil is further connected between the first pin and the second pin, and when a voltage difference is generated between the first pin and the second pin, a current may be generated, and the current flows through the driving coil, so as to drive the storage structure to be turned on. For example, the first designated voltage applied to the first pin by the main driving circuit 120 may be smaller than the second designated voltage applied to the second pin by the first power supply 130, or the first designated voltage applied to the first pin by the main driving circuit 120 may be larger than the second designated voltage applied to the second pin by the first power supply 130.

To further improve the reliability of the control of the storage structure, the controller 110 may further obtain the open/closed state of the storage structure, so as to monitor whether the open/closed state of the storage structure is abnormal.

In an alternative embodiment, the status feedback signal may be in the form of a voltage level, and the controller 110 may determine that the reservoir is open when the voltage at the third pin is high and the controller 110 may determine that the reservoir is closed when the voltage at the third pin is low.

In an alternative embodiment, the circuit configuration of the standby driving circuit 140 may be the same as that of the main driving circuit 120. For example, if the main driving circuit 120 cannot be used normally, the controller 110 will send a driving signal to the standby driving circuit 140 through the signal output terminal 111, the standby driving circuit 140 will apply a first specified voltage to the fourth pin of the storage structure, and since the first power source 130 continues to apply a second specified voltage to the second pin, a voltage difference will be generated between the fourth pin and the second pin of the storage structure, so as to drive the storage structure to be turned on.
In order to facilitate understanding of the control circuit provided in the above embodiments, the embodiment of the present invention provides a specific structure of the control circuit, taking the storage structure as a cashbox as an example, and refer to a schematic structural diagram of another control circuit shown in fig. 3.

Specifically, a driving coil is connected between the first pin 1 and the second pin 2, when a voltage difference is generated between the first pin 1 and the second pin 2, a current is generated at the moment, and the current flows through the coil to generate a magnetic force, so that the cashbox can be driven to be opened. At this time, when the voltage at the third pin 3 of the cashbox is at a high level, the controller 110 may determine that the storage structure is opened.
Referring to fig. 3, in fig. 3, for example, the control circuit includes a standby driving circuit 140, wherein the standby driving circuit 140 includes a third transistor Q3, a fourth transistor Q4, a third diode D3, a fourth diode D4, a fourth resistor R4, a fifth resistor R5, and a sixth resistor R6.

In one embodiment, the driving signal/EN _ CASH2 is low. In practical applications, the controller 110 may send a driving signal/EN _ CASH2, which may be "1115010003", to the standby driving circuit 140, when the standby driving circuit 140 receives the driving signal/EN _ CASH2, since the driving signal/EN _ CASH2 is at a low level, the voltage at the base of the third transistor Q3 is at a low level, the emitter and collector of the third transistor Q3 are turned off, the voltage at the base of the fourth transistor Q4 is at a high level, the emitter and collector of the fourth transistor Q4 are turned on, and the collector of the fourth transistor Q4 applies a first designated voltage to the fourth pin 4, wherein the voltage at the fourth pin 4 is at a low level, the voltage at the second pin 2 is at a high level, and a voltage difference is generated between the fourth pin 4 and the second pin 2. Specifically, a driving coil is connected between the fourth pin 4 and the second pin 2, when a voltage difference is generated between the fourth pin 4 and the second pin 2, a current is generated at the moment, and the current flows through the driving coil to generate a magnetic force, so that the opening of the cashbox can be determined.

In addition, fig. 3 also shows that the cashbox further comprises a fifth pin 5 and a sixth pin 6, and both the fifth pin 5 and the sixth pin 6 are grounded.
On the basis of the foregoing embodiment, the present invention further provides a description of the common problems and the detection method of the control circuit, and it is assumed that the control circuit cannot control the cashbox to open, as can be seen from the foregoing embodiment, the cashbox opening condition is that the voltage at the second pin 2 is 24V, and the voltage at the first pin 1 or the fourth pin 4 is at a low level, so when the cashbox cannot be normally opened, it may be first detected whether the voltage at the second pin 2 is normal, and then, when the driving signal is sent, it may be measured whether the voltages at the first pin 1 and the fourth pin 4 are at a low level. In practical applications, the reasons for the common problems are as follows: (1) the first triode Q1 and the second triode Q2 are damaged or in cold joint, wherein the probability of damage of the second triode Q2 is greater than that of damage of the first triode Q1; (2) the third triode Q3 and the fourth triode Q4 are damaged or in cold joint, and similarly, the probability of the damage of the fourth triode Q4 is greater than that of the damage of the third triode Q3; (3) the first resistor R1, the second resistor R2 and the third resistor R3 are damaged or cold-welded; (4) the fourth resistor R4, the fifth resistor R5 and the sixth resistor R6 are damaged or cold-welded.
