Through statistics because of mechanical electric mortiser lock card pause lead to selling the unable normal more than 20% of losing the single rate that leads to the fact of opening of cabinet door of cabinet to greatly influenced the direct income that the cabinet brought of selling.

Therefore, this application embodiment provides a cabinet door detecting system, can accurately detect the cabinet door state of selling the cabinet to realize virtual entrance guard's function according to this, so avoid the use to mechanical type lock.

Fig. 1 is a schematic structural diagram of a cabinet door detection system provided in an embodiment of the present application. Referring to fig. 1, the system includes: a first position detection assembly 1, a second position detection assembly 2 and a control unit 3; first position detection subassembly 1 and second position detection subassembly 2 are all installed on selling the cabinet body of cabinet, and output 1a and the first input 3a of the control unit 3 of first position detection subassembly 1 are connected, and output 2a and the second input 3b of the control unit 3 of second position detection subassembly 2 are connected.

The first position detection assembly 1 is used for generating a first voltage signal corresponding to the opening position of a cabinet door of the vending cabinet and transmitting the first voltage signal to the control unit 3; the control unit 3 is used for determining whether the cabinet door of the vending cabinet is opened or not according to the first voltage signal. The second position detection assembly 2 is used for generating a second voltage signal corresponding to the closing position of the cabinet door of the vending cabinet and transmitting the second voltage signal to the control unit 3; the control unit 3 is used for determining whether the cabinet door of the vending cabinet is closed or not according to the second voltage signal.

The opening position of the cabinet door of the vending cabinet is the position of the cabinet door of the vending cabinet when the cabinet door is opened, and the closing position of the cabinet door of the vending cabinet is the position of the cabinet door of the vending cabinet when the cabinet door is closed.

It should be noted that, the first position detecting assembly 1 is a member capable of detecting the position of the cabinet door when the cabinet door of the vending cabinet is opened, that is, the first voltage signal output by the first position detecting assembly 1 when the cabinet door of the vending cabinet is opened is different from the first voltage signal output when the cabinet door of the vending cabinet is not opened. The specific installation position of first position detection subassembly 1 on selling the cabinet body of cabinet can be selected according to the user demand, if first position detection subassembly 1 can install the position department that is located the cabinet door top in selling the cabinet body of cabinet.

In addition, the type of the first position detecting assembly 1 can be selected according to the use requirement. For example, the first position detecting assembly 1 may be a first infrared distance measuring sensor, and an infrared light emitting direction of the first infrared distance measuring sensor points to an opening position of a cabinet door of the vending cabinet. So, be in the opening position when selling the cabinet door of cabinet, also be when selling the cabinet door of cabinet and open, the infrared light of first infrared distance measuring sensor transmission can be by the cabinet door reflection of selling the cabinet, and the infrared light that reflects back can be detected by first infrared distance measuring sensor to just realized the accurate detection to the cabinet door position when the cabinet door of selling the cabinet is opened.

It should be noted that, the second position detecting assembly 2 is a member capable of detecting the position of the cabinet door when the cabinet door of the vending cabinet is closed, that is, the second voltage signal output by the second position detecting assembly 2 when the cabinet door of the vending cabinet is closed is different from the second voltage signal output when the cabinet door of the vending cabinet is not closed. The specific installation position of the second position detection assembly 2 on the cabinet body of the vending cabinet can be selected according to the use requirement, and the second position detection assembly 2 can be installed at the position above the cabinet door in the cabinet body of the vending cabinet.

In addition, the type of the second position detecting assembly 2 can be selected according to the use requirement. For example, the second position detecting assembly 2 may be a second infrared distance measuring sensor, and the infrared light emitting direction of the second infrared distance measuring sensor points to the closing position of the cabinet door of the vending cabinet. So, be in the closed position when the cabinet door of selling the cabinet, also be when selling the cabinet door of cabinet and close, the infrared light of second infrared distance measuring sensor transmission can be by the cabinet door reflection of selling the cabinet, and the infrared light that reflects back can be detected by second infrared distance measuring sensor to just realized the accurate detection to the cabinet door position when the cabinet door of selling the cabinet is closed.

It should be noted that the control unit 3 is a member for analyzing the first voltage signal and the second voltage signal to determine whether the door of the vending cabinet is opened or closed. The mounting position of the control unit 3 can be selected according to the use requirement, for example, the control unit 3 can be mounted on the inner top wall of the vending cabinet. The type of the control unit 3 can be selected according to the use requirement, for example, the control unit 3 can be an industrial personal computer or a single chip microcomputer.

It is worth mentioning that the first position detecting assembly 1 can detect an opening position of a cabinet door of the vending cabinet, the second position detecting assembly 2 can detect a closing position of the cabinet door of the vending cabinet, and the control unit 3 can determine whether the cabinet door of the vending cabinet is opened or closed according to detection results of the first position detecting assembly 1 and the second position detecting assembly 2. So, this cabinet door detecting system can accurate detection go out the cabinet door state of selling the cabinet to realize virtual entrance guard's function according to this, thereby can avoid the use of mechanical type lock. Moreover, the cabinet door detection system is low in cost, simple and convenient to install, simple to maintain and low in maintenance cost after a fault occurs.

When the first position detecting assembly 1 is a first infrared distance measuring sensor, the structure of the first infrared distance measuring sensor may be various, and one possible structure will be described below.

Referring to fig. 2, the first infrared distance measuring sensor may include a first infrared transmitting circuit 11 and a first infrared receiving amplifying circuit 12; a control end 11a of the first infrared transmitting circuit 11 is connected with a first control end 3c of the control unit 3, the first infrared transmitting circuit 11 is used for transmitting infrared light, and the infrared light transmitting direction of the first infrared transmitting circuit 11 points to the opening position of the cabinet door of the vending cabinet; an output end 12a of the first infrared receiving amplifying circuit 12 is connected with a first input end 3a of the control unit 3, and the first infrared receiving amplifying circuit 12 is used for receiving infrared light and generating a corresponding first voltage signal.

Note that the first infrared transmission circuit 11 is a circuit for transmitting infrared light. The first infrared transmitting circuit 11 may transmit infrared light upon receiving a control signal from the control unit 3. Wherein, the control unit 3 may periodically send a control signal to the first infrared emitting circuit 11 to control the first infrared emitting circuit 11 to periodically emit infrared light.

In addition, the first infrared receiving amplifying circuit 12 is a circuit for receiving infrared light and generating a corresponding first voltage signal. The first infrared receiving and amplifying circuit 12 may first generate a current signal corresponding to the light intensity when receiving the infrared light, and then amplify the current signal in multiple stages to obtain a first voltage signal.

Specifically, after the first infrared emitting circuit 11 receives the control signal sent by the control unit 3, the first infrared emitting circuit 11 emits infrared light toward the direction of the opening position of the cabinet door of the vending cabinet.

If the cabinet door of selling the cabinet is in the open position, the cabinet door of selling the cabinet opens promptly, then the infrared light that first infrared transmitting circuit 11 launched can be by the cabinet door reflection of selling the cabinet, and the infrared light that reflects back can be received by first infrared receiving and amplifying circuit 12, and first infrared receiving and amplifying circuit 12 can produce corresponding first voltage signal and send control unit 3.

If the cabinet door of selling the cabinet is not in the open position, the cabinet door of selling the cabinet does not open promptly, then the infrared light that first infrared emission circuit 11 launches can not be by the cabinet door reflection of selling the cabinet. At this time, the first infrared receiving and amplifying circuit 12 can only receive weak infrared light in natural light, and the first infrared receiving and amplifying circuit 12 can generate a corresponding first voltage signal and send the corresponding first voltage signal to the control unit 3.

Because the light intensity of the infrared light that is reflected back by the cabinet door of selling the cabinet can obviously be greater than the light intensity of the infrared light in the natural light, so the first voltage signal that first infrared receiving and amplifying circuit 12 produced when the cabinet door of selling the cabinet is opened can obviously be different from the first voltage signal that first infrared receiving and amplifying circuit 12 produced when the cabinet door of selling the cabinet is not opened.

In the case where the second position detecting element 2 is a second infrared distance measuring sensor, the second infrared distance measuring sensor may have various structures, and one possible structure will be described below.

Referring to fig. 3, the second infrared distance measuring sensor may include a second infrared transmitting circuit 21 and a second infrared receiving amplifying circuit 22; the control end 21a of the second infrared transmitting circuit 21 is connected with the second control end 3d of the control unit 3, the second infrared transmitting circuit 21 is used for transmitting infrared light, and the infrared light transmitting direction of the second infrared transmitting circuit 21 points to the closing position of the cabinet door of the vending cabinet; an output end 22a of the second infrared receiving and amplifying circuit 22 is connected with a second input end 3b of the control unit 3, and the second infrared receiving and amplifying circuit 22 is used for receiving infrared light and generating a corresponding second voltage signal.

Note that the second infrared transmission circuit 21 is a circuit for transmitting infrared light. The second infrared transmission circuit 21 may transmit infrared light upon receiving a control signal from the control unit 3. Wherein, the control unit 3 may periodically send a control signal to the second infrared transmitting circuit 21 to control the second infrared transmitting circuit 21 to periodically transmit the infrared light.

In addition, the second infrared receiving and amplifying circuit 22 is a circuit for receiving infrared light and generating a corresponding second voltage signal. The second infrared receiving and amplifying circuit 22 may first generate a current signal corresponding to the light intensity when receiving the infrared light, and then amplify the current signal in multiple stages to obtain a second voltage signal.

Specifically, after the second infrared transmitting circuit 21 receives the control signal sent by the control unit 3, the second infrared transmitting circuit 21 transmits infrared light toward the direction of the closing position of the cabinet door of the vending cabinet.

If the cabinet door of selling the cabinet is in the closed position, that is to say the cabinet door of selling the cabinet is closed, then the infrared light that second infrared transmitting circuit 21 launched will be reflected by the cabinet door of selling the cabinet, and the infrared light that reflects back will be received by second infrared receiving and amplifying circuit 22, and second infrared receiving and amplifying circuit 22 will produce corresponding second voltage signal and send control unit 3.

If the cabinet door of selling the cabinet is not in the closed position, sell the cabinet door of cabinet and do not close promptly, then the infrared light that second infrared emission circuit 21 launches can not be by selling the cabinet door reflection of cabinet. At this time, the second infrared receiving and amplifying circuit 22 can only receive weak infrared light in natural light, and the second infrared receiving and amplifying circuit 22 generates a corresponding second voltage signal and sends the second voltage signal to the control unit 3.

Because the light intensity of the infrared light reflected back by the cabinet door of the vending cabinet can be obviously greater than the light intensity of the infrared light in the natural light, the second voltage signal generated by the second infrared receiving and amplifying circuit 22 when the cabinet door of the vending cabinet is closed can be obviously different from the second voltage signal generated by the second infrared receiving and amplifying circuit 22 when the cabinet door of the vending cabinet is not closed.

There are many possible configurations of the control unit 3, and one possible configuration will be described below.

Referring to fig. 4, the control unit 3 includes an analog-to-digital converter 31 and a processor 32; a first input end 31a of the analog-to-digital converter 31 is connected with the output end 1a of the first position detecting assembly 1, a first output end 31b of the analog-to-digital converter 31 is connected with a first input end 32a of the processor 32, and the first input end 31a of the analog-to-digital converter 31 corresponds to the first output end 31 b; a second input terminal 31c of the analog-to-digital converter 31 is connected to the output terminal 2a of the second position detecting assembly 2, a second output terminal 31d of the analog-to-digital converter 31 is connected to a second input terminal 32b of the processor 32, and a second input terminal 31c of the analog-to-digital converter 31 corresponds to the second output terminal 31 d.

The analog-to-digital converter 31 is configured to convert the first voltage signal into a first voltage value, and transmit the first voltage value to the processor 32; the processor 32 is configured to determine that the door of the vending cabinet is open when the first voltage value is within the first voltage range. The analog-to-digital converter 31 is configured to convert the second voltage signal into a second voltage value, and transmit the second voltage value to the processor 32; the processor 32 is configured to determine that the door of the vending cabinet is closed when the second voltage value is within the second voltage range.

The Analog-to-Digital Converter (ADC) 31 is an electronic component that converts an Analog signal into a Digital signal. The processor 32 is an operation and control core of the control unit 3, and is a main execution unit for information processing and program operation.

Furthermore, the first voltage range and the second voltage range can be set according to the use requirement. The first voltage range depends on the light intensity of the infrared light reflected back by the cabinet door when the cabinet door of the vending cabinet is opened, and thus the first voltage range can be set according to the distance between the first position detection assembly 1 and the opening position of the cabinet door of the vending cabinet. The second voltage range depends on the light intensity of the infrared light reflected back by the cabinet door when the cabinet door of the vending cabinet is closed, and thus the second voltage range may be set according to the distance between the second position detection assembly 2 and the closed position of the cabinet door of the vending cabinet. For example, the first voltage range may be 3V to 5V, and the second voltage range may be 3V to 5V.

Because the light intensity of the infrared light that is reflected back by the cabinet door of selling the cabinet can obviously be greater than the light intensity of the infrared light in the natural light, so the first voltage signal that first position detection subassembly 1 produced when the cabinet door of selling the cabinet is opened can obviously be different from the first voltage signal that first position detection subassembly 1 produced when the cabinet door of selling the cabinet is not opened, specifically be when the cabinet door of selling the cabinet is opened first voltage value that first voltage signal that first position detection subassembly 1 produced corresponds can be greater than the first voltage value that first voltage signal that first position detection subassembly 1 produced when the cabinet door of selling the cabinet is not opened corresponds. Under this condition, the first voltage value that the first voltage signal that first position detection subassembly 1 produced when selling the cabinet door of cabinet is opened can be in first voltage range, and the first voltage value that the first voltage signal that first position detection subassembly 1 produced when selling the cabinet door and not opening can not be in first voltage range. The processor 32 may thus determine that the door of the merchandiser is open when the first voltage value is within the first voltage range; and when the first voltage value is not in the first voltage range, determining that the cabinet door of the vending cabinet is not opened. So, can comparatively fast and confirm accurately whether the cabinet door of selling the cabinet is opened.

Because the light intensity of the infrared light that is reflected back by the cabinet door of selling the cabinet can obviously be greater than the light intensity of the infrared light in the natural light, so when selling the cabinet door of cabinet and close the second voltage signal that second position detection subassembly 2 produced can obviously be different from when selling the cabinet door of cabinet and not closing the second voltage signal that second position detection subassembly 2 produced, specifically the second voltage value that second voltage signal that second position detection subassembly 2 produced corresponds can be greater than when selling the cabinet door of cabinet and not closing the second voltage value that second voltage signal produced of second position detection subassembly 2 produced. Under this condition, the second voltage value that the second voltage signal that second position detection subassembly 2 produced when selling the cabinet door of cabinet is closed can be in the second voltage range, and the second voltage value that the second voltage signal that second position detection subassembly 2 produced when selling the cabinet door and not closing can not be in the second voltage range. The processor 32 may thus determine that the doors of the merchandiser are closed when the second voltage value is within the second voltage range; and when the second voltage value is not in the second voltage range, determining that the cabinet door of the vending cabinet is not closed. So, can comparatively confirm fast and accurately whether the cabinet door of selling the cabinet is closed.

Further, in addition to the above devices, other devices may be included in the cabinet door detection system, which will be described below.

Optionally, referring to fig. 5, the system further comprises a speaker 4, the speaker 4 being connected to the first output 3e of the control unit 3.

It should be noted that the loudspeaker 4 is an electroacoustic transducer device, which can convert an electric signal into an acoustic signal. The type of the speaker 4 can be selected according to the usage requirement, and for example, the speaker 4 can be an electrodynamic speaker, an electrostatic speaker, an electromagnetic speaker, or the like.

Specifically, when adopting this cabinet door detecting system to detect the cabinet door of selling the cabinet, confirm when the cabinet door of selling the cabinet of the control unit 3 opens or closes the back, control unit 3 can carry out corresponding warning to the user through speaker 4 according to the cabinet door state of selling the cabinet. So, can be convenient for the user carry out corresponding operation fast to can improve and sell efficiency.

Optionally, referring to fig. 6, the system further comprises a display 5, the display 5 being connected to the second output 3f of the control unit 3.

It should be noted that the installation position of the display 5 can be selected according to the use requirement, for example, the display 5 can be installed in the cabinet body of the vending cabinet at a position above the cabinet door. The control unit 3 can display some information that needs to be known by the user during the article selling process through the display 5, thereby improving the selling efficiency.

In this application embodiment, first position detection subassembly 1 can detect the open position of selling the cabinet door of cabinet, and second position detection subassembly 2 can detect the closed position of selling the cabinet door of cabinet, and whether the control unit 3 can confirm the cabinet door of selling the cabinet according to the testing result of first position detection subassembly 1 and second position detection subassembly 2 and open or close. So, this cabinet door detecting system can accurate detection go out the cabinet door state of selling the cabinet to realize virtual entrance guard's function according to this, thereby can avoid the use of mechanical type lock. And need not to carry out destructive transformation to selling the cabinet when installing this cabinet door detecting system, consequently the installation cost is lower, and the installation is also comparatively simple and convenient.

Fig. 8 is a flowchart of a resource transfer method provided in an embodiment of the present application, where the method is applied to a control unit in a cabinet door detection system shown in the foregoing embodiment. Referring to fig. 8, the method includes:

step 801: if the control unit detects that the cabinet door of the selling cabinet is opened through the first position detection assembly, whether the indication message sent by the server is received within a first time period before and after the cabinet door of the selling cabinet is opened is judged.

It should be noted that, the operation that the control unit detects whether the cabinet door of the vending cabinet is opened or not through the first position detecting assembly has been described in detail in the above embodiments, and this is not described again in the embodiments of the present application.

In addition, the first time length can be set according to the use requirement, and the first time length can be set to be smaller. For example, the first duration may be 5 seconds, 10 seconds, etc.

It should be noted that the indication message is sent to the control unit by the server after detecting the scanning operation of the terminal on the graphic code. The graphic code is a graphic which is distributed on a plane (in two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is black and white and is alternated and records data symbol information, and can be a bar code, a two-dimensional code and the like. The graphic code comprises a control unit identifier. The control unit identifier is used to uniquely identify the control unit, and may be an IP (Internet Protocol) address of the control unit, a factory serial number, and the like.

In addition, after the terminal scans the graphic code, the control unit identifier contained in the graphic code is read. And then the terminal sends a login message carrying the control unit identifier to the server. When the server receives the login message, an indication message is generated and sent to the control unit identified by the control unit identifier. Thus, the control unit can determine that the terminal performs the scanning operation on the graphic code when receiving the indication message.

In order to facilitate the terminal to perform the scanning operation on the graphic code, the control unit may display the graphic code on the display shown in the above embodiments. Therefore, when the user needs to use the vending cabinet, the graphic code can be quickly and conveniently scanned through the terminal.

If the control unit detects that the cabinet door of selling the cabinet is opened, then can judge whether receive the instruction message that the server sent in the first time period around the cabinet door of selling the cabinet is opened, also judge whether the user has used terminal to scan graphic code when opening the cabinet door of selling the cabinet, also judge whether the mode that the user opened the cabinet door is normal promptly.

If the control unit receives the indication message sent by the server within a first time period before and after the door of the vending cabinet is opened, executing the following steps 802-804; if the control unit does not receive the indication message sent by the server within the first time period before and after the door of the vending cabinet is opened, the following steps 805 to 806 are executed.

Step 802: if the control unit receives the indication message sent by the server within a first time period before and after the door of the vending cabinet is opened, the article taking-out condition in the vending cabinet is detected.

It should be noted that, if the control unit receives the indication message sent by the server within the first time period before and after the cabinet door of the vending cabinet is opened, it indicates that the user uses the terminal to scan the graphic code when opening the cabinet door of the vending cabinet, that is, the user opens the cabinet door normally. At the moment, the user can normally take the articles in the vending cabinet, and meanwhile, the control unit can detect the taking condition of the articles in the vending cabinet, so that the resources needing to be paid by the user can be determined according to the detection result. The article removal condition may reflect the articles removed from the vending cabinet by the user, and may include the type and number of articles removed from the vending cabinet, and the like.

Wherein, there are a plurality of modes of the control unit detection selling the article condition in the cabinet and taking out. For example, the control unit may detect the article removal condition in the vending cabinet through a weighing recognition method, or the control unit may detect the article removal condition in the vending cabinet through a combination of the weighing recognition method and an image recognition method, and of course, the control unit may detect the article removal condition in the vending cabinet through other methods, which is not limited in this embodiment of the present application.

Step 803: if the control unit detects that the cabinet door of the selling cabinet is closed through the second position detection assembly, the quantity of resources required by the articles taken out of the selling cabinet in the process of opening the cabinet door of the selling cabinet to closing the cabinet door is determined.

It should be noted that, the operation that the control unit detects whether the cabinet door of the vending cabinet is closed through the second position detecting assembly has been described in detail in the above embodiments, and this is not described again in the embodiments of the present application.

In addition, because the control unit detects the article condition of taking out in the cabinet of selling always detecting after the cabinet door that sells the cabinet is opened, so after the cabinet door that detects the cabinet of selling, the control unit can learn the article of taking out from selling the cabinet in the in-process that the cabinet door was opened to the cabinet door was closed selling the cabinet, just then can confirm the required resource quantity of article of taking out.

The control unit may store a correspondence between the article type and the resource amount in advance, and the resource amount corresponding to a certain article type may be the resource amount required for the article of the article type. When the control unit determines the resource quantity required by the articles taken out of the vending cabinet in the process from the opening of the cabinet door of the vending cabinet to the closing of the cabinet door, the control unit can acquire the resource quantity corresponding to the type of each article in all the articles taken out of the vending cabinet in the process from the opening of the cabinet door of the vending cabinet to the closing of the cabinet door from the corresponding relation, and then accumulate all the acquired resource quantities to obtain the resource quantity required by the articles taken out of the vending cabinet in the process from the opening of the cabinet door of the vending cabinet to the closing of the cabinet door.

Step 804: and the control unit sends a resource transfer request carrying the resource quantity to the server.

It should be noted that the resource transfer request is used to request to transfer the resource of the resource amount.

Further, after receiving the resource transfer request, the server may determine a first user account corresponding to the terminal that performs the scanning operation on the graphic code before, determine a second user account corresponding to the control unit, and then transfer the resource of the resource amount from the first user account corresponding to the terminal to the second user account corresponding to the control unit.

The first user account corresponding to the terminal is an account used by a buyer who takes out an article from the vending cabinet, and the second user account corresponding to the control unit is an account used by a seller corresponding to the vending cabinet.

The server may store a correspondence between the device identifier and the user account in advance. The server may use both the terminal identifier and the control unit identifier as the device identifier, then obtain a user account corresponding to the terminal identifier from the corresponding relationship as the first user account, and obtain a user account corresponding to the control unit identifier from the corresponding relationship as the second user account. The terminal identifier is used for uniquely identifying the terminal, and the terminal identifier may be an IP address, a factory serial number, and the like of the terminal.

It should be noted that, when the server transfers the resource of the resource amount from the first user account to the second user account, the resource of the resource amount may be directly transferred from the first user account to the second user account upon receiving the resource transfer request; or, when receiving the resource transfer request, first sending a resource transfer reminding message carrying the resource amount to the terminal, and when receiving a confirmation message for the resource transfer reminding message returned by the terminal, transferring the resource amount from the first user account to the second user account.

Furthermore, after the server successfully transfers the resource of the resource amount from the first user account to the second user account, the server may send a resource transfer success message to the control unit, and at this time, the shopping process of the terminal is ended. If the server does not transfer the resources of the resource amount from the first user account to the second user account successfully, the server may not send a resource transfer success message to the control unit within the second duration, or may return a resource transfer failure message to the control unit, where the shopping flow of the terminal is not completed yet.

That is to say, if the control unit does not receive the resource transfer success message returned by the server within the second duration after sending the resource transfer request to the server, or if the control unit receives the resource transfer failure message returned by the server after sending the resource transfer request to the server, the control unit may determine that the second user account corresponding to the control unit does not obtain the resource requested to be transferred yet, and thus the control unit may play a first reminding voice using the speaker at this time, where the first reminding voice is used to remind the user of transferring the resource.

It should be noted that the second time period may be set according to the use requirement, for example, the second time period may be 10 seconds, 15 seconds, and the like.

In addition, the first reminding voice can remind the user of paying resources for the current articles taken out of the selling cabinet in time when the resource transfer fails, so that the user can conveniently use the terminal to perform resource transfer operation in time, the resource transfer efficiency is improved, and the shopping efficiency is further improved.

The above steps 802 to 804 are operations executed by the control unit when the control unit receives the indication message sent by the server within the first time period before and after the cabinet door of the vending cabinet is opened, that is, operations executed by the control unit when the mode of opening the cabinet door by the user is normal, and are normal shopping processes.

The following describes an operation performed by the control unit when the indication message sent by the server is not received within a first time period before and after the cabinet door of the vending cabinet is opened, that is, an operation performed by the control unit when the mode of opening the cabinet door by the user is abnormal, which specifically includes the following steps 805 to 806, which are an abnormal reminding process.

Step 805: if the control unit does not receive the instruction message that the server sent in the first time length before and after the cabinet door of selling the cabinet is opened, then use speaker broadcast second to remind pronunciation, the second is reminded pronunciation and is used for reminding needs to sweep the sign indicating number and open the door.

It should be noted that, if the control unit does not receive the indication message sent by the server within the first duration before and after the cabinet door of the vending cabinet is opened, it indicates that the user does not use the terminal to scan the graphic code when opening the cabinet door of the vending cabinet, that is, the way in which the user opens the cabinet door is abnormal, and at this time, the user is not allowed to take the article from the vending cabinet. In this case, the control unit may use the speaker to play a second reminding voice to remind the user to open the door by scanning the code.

In addition, the voice can remind the user that the graphic code needs to be scanned when the cabinet door of the vending cabinet is opened without scanning the code by the user, so that the user can conveniently use the terminal to scan the graphic code in time, and the normal operation of a follow-up shopping process is facilitated.

The operation of the control unit playing the second reminding voice by using the speaker may be: if the control unit does not detect that the cabinet door of selling the cabinet is closed, then use speaker circulation broadcast second to remind pronunciation. So, can open the mode of cabinet door when the user is unusual, remind the user to use the terminal to scan the operation to the figure code many times before the user closes the cabinet door to can improve user's the yard efficiency of opening the door of sweeping.

It should be noted that the operation of detecting whether the cabinet door of the vending cabinet is closed by the control unit has been described in detail in the above embodiments, and this is not described again in the embodiments of the present application.

In addition, the time interval of the control unit for circularly playing the second reminding voice by using the loudspeaker can be set according to the use requirement. For example, the control unit may play the second alert tone once every 2 seconds using the speaker.

Further, in the process that the control unit uses the loudspeaker to circularly play the second reminding voice, the control unit can also detect the condition that the articles in the vending cabinet are taken out. So, can open the mode of cabinet door when unusual at the user, whether the control user has taken article from selling the cabinet.

Step 806: if the control unit detects through second position detection assembly that the cabinet door of selling the cabinet is closed, and detect to sell and have article in the cabinet and take out, then use speaker broadcast third to remind pronunciation, the third is reminded pronunciation and is used for reminding the article that need take out to put back and sells the cabinet.

It should be noted that, the operation that the control unit detects whether the cabinet door of the vending cabinet is closed through the second position detecting assembly has been described in detail in the above embodiments, and this is not described again in the embodiments of the present application.

If the control unit detects that there is article to be taken out in selling the cabinet to the in-process that the cabinet door was closed at the cabinet door of selling the cabinet is opened, then explain that the user has taken the article in selling the cabinet under the condition that the code is not swept and the door is opened. Since the user does not scan the code to open the door, the server cannot know the terminal used by the user who currently takes the article, and thus the resource transfer operation cannot be executed. That is to say, under the condition that the user does not scan the sign indicating number and open the door, even the user has taken article from selling the cabinet, the control unit also can't request the server to carry out the resource transfer, therefore under this condition, the control unit needs to use speaker broadcast third warning pronunciation to remind the user to put the article of taking back to selling the cabinet.

In addition, the third reminds pronunciation can in time remind the user to put back the article of taking and sell the cabinet when the user has not scanned sign indicating number and has opened the door and taken the article of selling in the cabinet again to this reduces article and loses the probability.

It is worth explaining, this application embodiment installs first position detection subassembly and second position detection subassembly in selling the cabinet, and the control unit can detect the cabinet door state of selling the cabinet through first position detection subassembly and second position detection subassembly, detects that the cabinet door is opened or is closed promptly. And in addition, by matching with graphic code scanning and loudspeaker voice reminding, the controller can execute a normal shopping flow when a user scans a code and opens the door, and execute an abnormal reminding flow when the user does not scan the code and opens the door, so that the virtual access control function is realized.

In this application embodiment, the control unit detects that the cabinet door of selling the cabinet is opened through first position detection subassembly, and when receiving the instruction message that the server sent in the first time span before and after the cabinet door of selling the cabinet is opened, detects the condition of taking out of article in selling the cabinet, and instruction message is that the server sends after detecting the scanning operation of terminal to graphic code. Afterwards, if the control unit detects that the cabinet door of the vending cabinet is closed through the second position detection assembly, the quantity of resources required by the articles taken out of the vending cabinet in the process from the opening of the cabinet door of the vending cabinet to the closing of the cabinet door is determined. And finally, the control unit sends a resource transfer request carrying the resource quantity to the server, and instructs the server to transfer the resource quantity from the first user account corresponding to the terminal to the second user account corresponding to the control unit. So, when the user sweeps the sign indicating number and opens the door, the control unit can realize the resource transfer to the article of taking out from selling the cabinet automatically according to the cabinet door state of selling the cabinet to not only can improve resource transfer efficiency, can simplify user's shopping flow moreover, the user of being convenient for uses.

In order to make the technical solutions and advantages of the embodiments of the present application clearer, the following detailed description will be made with reference to alternative embodiments.

If the control unit receives the indication message sent by the server within a first time period before and after the door of the vending cabinet is opened, the control unit can determine that the user is a code scanning door opening; if the control unit does not receive the indication message sent by the server within the first time before and after the cabinet door of the vending cabinet is opened, the control unit can determine that the user does not scan the code to open the door.

If the user is to sweep the sign indicating number and open the door, then the user can normally take out article from selling the cabinet, and the control unit can detect the article condition of taking out in selling the cabinet this moment. When the user closed the cabinet door of selling the cabinet, the control unit can detect through second position detection subassembly that the cabinet door of selling the cabinet is closed. At this time, the control unit determines the quantity of resources required by the articles taken out of the vending cabinet in the process from the opening of the cabinet door of the vending cabinet to the closing of the cabinet door, and sends a resource transfer request carrying the quantity of the resources to the server so as to instruct the server to transfer the resources of the quantity of the resources from the first user account corresponding to the terminal to the second user account corresponding to the control unit. Then, if the control unit receives a resource transfer success message returned by the server, the characters of successful shopping, thank you and the like can be displayed on the display; if the control unit does not receive the resource transfer success message returned by the server within the second time length, or the control unit receives the resource transfer failure message returned by the server, the first reminding voice can be played by using the loudspeaker to remind the user of the need of transferring the resource.

If the user does not scan the code to open the door, the control unit uses the loudspeaker to circularly play a second reminding voice to remind the user that shopping can be carried out only by scanning the code to open the door. And the control unit detects the article taking-out condition in the vending cabinet in the process of circularly playing the second reminding voice by using the loudspeaker. When the user closed the cabinet door of selling the cabinet, the control unit can detect through second position detection subassembly that the cabinet door of selling the cabinet is closed. At this moment, if the control unit detects that the cabinet door of the selling cabinet is opened to the in-process that the cabinet door is closed, the third reminding voice is played by using the loudspeaker to remind the user to put back the taken article to the selling cabinet. After the control unit detects that the articles taken out are all put back to the vending cabinet and the cabinet door of the vending cabinet is detected to be closed again through the second position detection assembly, the user can reopen the cabinet door of the vending cabinet to take the articles.
