Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, in an embodiment of the method and the apparatus for determining an article dispensing state of a vending machine according to the present invention, the method for determining an article dispensing state of a vending machine includes the following steps:
step S11 collects motor rotation signals: in this step, when the motor of the current cargo channel for pushing out the cargo starts to rotate, a rotation signal of the motor is acquired. For the embodiment, the automatic vending equipment comprises a plurality of goods channels, and each goods channel is provided with a goods channel motor; when a user selects or purchases an article and pays for the article, the control unit of the automatic vending equipment selects a goods channel for placing the article according to the preset setting (the same article is placed on one goods channel, and one article can be placed by a plurality of goods channels), and then outputs a control signal, so that the motor of the goods channel rotates by a set angle, and the goods channel can push out one article placed on the goods channel, fall downwards and enter a goods taking area. In the prior art, the ejection of an article is typically achieved by controlling the duration of the signal. Such methods, while sometimes also enabling the ejection of items or goods, may also present problems in some cases. For example, although the control signal is applied to the motor, the motor is not rotated or rotates very slowly due to the blockage of the goods passage by the goods, and the system cannot detect that the control signal is maintained for a set time, but the goods are not pushed out. The system may misunderstand that the transaction has been completed, thus resulting in customer complaints requiring refunds. In the prior art, manual intervention is required at this time to perform a series of operations such as confirmation, refund and the like. Thereby having a negative impact on labor costs, time and customer satisfaction. To solve this problem, in this embodiment, for each cargo way motor, a motor shaft position detecting unit is provided, which is disposed on the motor shaft and detects the rotation position of the motor shaft, and the signal output by the motor shaft position detecting unit is the motor rotation signal, and in this step, this signal is collected to obtain the signal.
In this embodiment, the motor shaft position detecting unit includes a rotating piece 21 having a set shape and a switch 23 connected to a motor shaft 22, and the rotating piece 21 triggers or does not trigger the switch 23 with the rotation of the motor shaft, so that the switch 23 outputs output signals of different levels to obtain the motor rotation signal. Referring to fig. 2, the rotary plate 21 includes a circular sheet-shaped object with an arc cut away, a mounting hole is formed at the center of the circular sheet-shaped object, and the rotary plate 21 is connected to the motor shaft 22 through the mounting hole; the switch 23 is arranged on a mounting piece 24, the mounting piece 24 is arranged at a position that the switch 23 is contacted with the circular arc part of the rotating piece 21, so that when the circular arc part of the rotating piece 21 rotates to the position of the switch 23, the switch 23 is contacted to output a signal with a specified level; when the position of the cut-off arc of the rotary piece 21 is rotated to the position of the switch 23, the switch 23 outputs another signal of a specified level because of no contact with the switch 23.
Step S12, if the signal is normal, executing step S13; otherwise, step S14 is executed. In this step, one of the most basic operations is to determine the motor rotation signal, and when the cut-off arc portion of the upper rotating piece 21 is rotated to the position of the switch 23 as shown in fig. 2 and the above description, the level of the motor rotation signal is different from the level when the other arc portion contacts the switch, and thereby the position of the motor rotation shaft can be determined. When the motor rotates normally, the waveform of the motor rotation signal is fixed and known, so that whether the signal is normal or not, namely whether the rotation of the motor rotating shaft is normal or not can be judged according to the level of the motor rotation signal.
Step S13, the goods are normally sent, and the shipment is finished: in this step, since it is determined that the motor is rotating normally, the pushing or sending of the article is considered to be normal, that is, the transaction is normal, and the shipment is ended.
Step S14 is a dialog box generated, the user confirms whether the item is obtained, if the user confirms that the item is obtained, step S15 is executed; if the user feedbacks that the article is not obtained, executing step S16; in this step, since the motor rotation signal is not normal, in order to confirm whether the motor shaft position detection unit has a fault, a step of human-machine interaction is added, a dialog box or dialog is generated on the screen of the automatic vending equipment, a user is required to confirm whether the purchased goods are received, if the user confirms that the goods are received, it is determined that the motor shaft position detection unit has a fault, and the motor rotation signal is not normal, and then step S15 is executed; if the user' S feedback indicates that he or she has not received the goods, it is determined that the lane has a failure, the lane number is recorded, and if necessary, the lane needs to be temporarily stopped, and a maintenance person waits for maintenance, and step S16 is performed.
Step S15, determining a failure of the motor shaft position detection unit, generating maintenance information: in this step, since the goods is normally delivered from the goods passage, the user has received or obtained the goods, but the motor rotation signal is not normal, it is determined that the motor shaft position detecting unit is faulty, and maintenance information is generated, requiring the maintenance personnel to go to the field for processing.
Step S16 executes the re-shipment program: in this step, since the shipment fails in the shipping lane, the user executes the re-shipment program in order to acquire the purchased items. In this procedure, another lane on which the same goods or items are placed is rotated for shipment. It should be noted that, in this embodiment, the above determination step is performed in the same manner in the re-shipment program, but it is marked as re-shipment, and if the re-shipment program still fails to deliver the money, the user order is directly cancelled without entering the re-shipment program again, and the user money is returned as it is. The method has the advantages that the method can ensure the volume of the transaction as much as possible, and can timely return the user money when the equipment is in fault, thereby improving the satisfaction degree and the user experience of the user.
In the present embodiment, the above-described functions can be achieved only by determining the above-described motor rotation signal as described above in some cases. However, in some cases of this embodiment, more sensor signals are added and the integrated determination is performed together with the motor rotation signal, so that the determination result is more reliable. Such as a current box number added to the motor or an infrared article detection signal.
Therefore, in some cases in this embodiment, the determination in step S12 may also be added to the determination of the article detection signal, that is, in step S12, the signals output by the infrared correlation units arranged on both sides of the cargo passage within the set time may also be collected, and whether the output signal of the single infrared pair transistor in the signals is interrupted and then recovered is determined, if the interruption and recovery occurs, it is determined that the article detection signal is normal, otherwise, the article detection signal is not normal; then, the state of the article detection signal is combined with the state of the motor rotation signal to further confirm and judge the current article issuing state; in this case, the states include:
if the motor rotation signal and the article detection signal are normal, judging that the article issuing state is normal;
if the motor rotation signal is normal and the article detection signal is abnormal, the article distribution state is still judged to be normal, and the maintenance information of the article detection part is generated to require the maintenance of the infrared correlation unit;
if the motor rotation signal is not normal and the article detection signal is normal or if the motor rotation signal and the article detection signal are not normal, step S14 is performed.
In some cases in the present embodiment, the above-described article detection signal is output by infrared correlation units provided on both sides of a space where an article enters the pickup area after being pushed out of the cargo way. Referring to fig. 3, the infrared correlation unit includes a light emitting plate 31 disposed at one side of the space and a light receiving plate 32 disposed at the other side of the space, the light emitting plate and the light receiving plate are both vertical and elongated, and a plurality of light emitting tubes (shielded in fig. 3 because of the angle relationship) and light receiving tubes 34 are disposed on the surfaces of the light emitting plate and the light receiving plates at intervals from top to bottom to form a light curtain for objects entering the goods taking area to pass through during falling, and a plurality of signals respectively outputted by the light receiving tubes 34 on the light receiving plate 32 and indicating whether the light receiving tubes receive light signals constitute the object detection signals.
