[0034] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Figure 1 is a schematic diagram of the structure of the intelligent meal cabinet according to an embodiment of the present invention. Figure 1 As shown, the smart meal cabinet includes: a meal retrieval trolley, including a connected cantilever and a meal retrieval platform, the cantilever is used to realize the movement of the meal retrieval platform, and the meal boxes are placed on the meal retrieval platform; a meal delivery platform, used to receive the meal boxes pushed out by the meal delivery platform; a meal delivery port, arranged on the meal delivery platform, the meal boxes on the meal retrieval platform are pushed to the meal delivery platform through the meal delivery port, and the user takes the meal boxes on the meal delivery platform; a photoelectric switch, arranged at the meal delivery port, is used to detect obstructions to the meal delivery port.

[0037] This embodiment provides a photoelectric switch at the food outlet of the smart food cabinet, so as to timely and accurately detect whether there is an obstruction at the food outlet, that is, whether the user reaches out to the food outlet, and timely identify the risk of the user's hand being pinched.

[0038] In the specific implementation, a photoelectric switch can be set horizontally at the food outlet of the smart food cabinet. The photoelectric switch and the cantilever of the food retrieval cart work together. The photoelectric switch can be set as a photoelectric sensor. In the normal state, the photoelectric switch is in the on state. When the photoelectric switch detects an obstruction at the food outlet, it switches from the on state to the off state.

[0039] Considering how to resolve the risk of the user's hand being pinched after the risk is detected, and to prevent the user from actually being pinched, this embodiment proposes a preferred implementation method, such as Figure 2 The control principle diagram of the intelligent meal cabinet shown in FIG. Figure 2 As shown, the above-mentioned smart meal cabinet also includes: a controller (controller processing and storage unit), which is used to detect the state of the photoelectric switch after receiving the user's purchase instruction; if the photoelectric switch is detected to be in the disconnected state, the cantilever is controlled to move the meal pickup platform away from the meal delivery platform. Based on this, when it is detected that the user has a risk of pinching the hand, the movement trajectory of the meal pickup trolley is adjusted in time to avoid the occurrence of pinching the hand. The reliability of the smart meal cabinet is improved, the user experience and safety are enhanced, and the after-sales labor costs are saved to a certain extent.

[0040] Example 2

[0041] According to an embodiment of the present invention, an embodiment of an anti-pinch control method for an intelligent food cabinet is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0042] Figure 3 is a flow chart of a hand pinching prevention control method of an intelligent dining cabinet according to an embodiment of the present invention. Figure 3 As shown, the method comprises the following steps:

[0043] Step S301, after receiving the user's purchase instruction, detecting the state of the photoelectric switch at the dining port;

[0044] Step S302, if it is detected that the photoelectric switch is in the off state, the cantilever is controlled to move the meal taking platform away from the meal dispensing platform;

[0045] Among them, a photoelectric switch is arranged at the food outlet of the intelligent food cabinet. When the photoelectric switch detects that there is an obstruction at the food outlet, the photoelectric switch switches from the on state to the off state.

[0046] In this embodiment, a photoelectric switch is set at the food outlet of the smart food cabinet to detect whether there is an obstruction at the food outlet, that is, whether the user reaches out to the food outlet. This ensures that when the risk of the user's hand being pinched is detected, the movement trajectory of the food pickup trolley is adjusted to avoid the occurrence of hand pinching. The reliability of the smart food cabinet is improved, the user experience and safety are enhanced, and the after-sales labor costs are saved to a certain extent.

[0047] After receiving the purchase instruction from the user, the intelligent food cabinet detects the state of the photoelectric switch at the meal outlet. Specifically, after receiving the purchase instruction from the user, it determines whether the meal pickup platform has reached the meal outlet. If the meal pickup platform has not reached the meal outlet, it means that the meal box has not been delivered to the meal outlet and the user has not taken the meal box, so the state of the photoelectric switch at the meal outlet is detected. If the meal pickup platform has reached the meal outlet, it is necessary to further determine whether the meal box has been delivered to the meal outlet and whether the user has taken the meal. Therefore, it is detected whether there is a meal box on the meal outlet within a preset time. If there is a meal box, it means that the meal box has reached the meal outlet through the meal outlet, and there is almost no risk of the user's hand being pinched at the meal outlet. Therefore, the state of the photoelectric switch at the meal outlet can be stopped. Based on this, when it is determined that there is almost no risk of the user's hand being pinched at the meal outlet, the detection operation can be stopped to reduce resource waste.

[0048] If there is no lunch box on the meal delivery platform, it means that the lunch box may have been taken away directly by the user, for example, the user directly took the lunch box on the meal delivery platform through the meal delivery port, so it is necessary to detect the state of the photoelectric switch at the meal delivery port; if the photoelectric switch is detected to be in the disconnected state, it means that there is an obstruction at the meal delivery port, and it is further determined that the user has reached out at the meal delivery port, then it is confirmed that the lunch box has been taken out and the purchase process is over. Based on this, it is possible to confirm in real time whether the lunch box has been taken away and the user's purchase process has ended, avoiding the erroneous operation that the user directly takes the lunch box from the meal delivery platform through the meal delivery port, but the meal delivery platform does not detect the lunch box and determines that the purchase process is not over.

[0049] After detecting that the photoelectric switch is in the disconnected state, the present embodiment controls the cantilever to move the meal-taking platform away from the meal-dispensing platform, thereby avoiding the risk of the user's hand being pinched. In a specific implementation, one or more preset points can be set in advance, and the preset points maintain a preset distance from the meal-dispensing platform. The preset distance can ensure that the user will not be pinched or stuck even if he or she reaches his or her hand (or other foreign objects) in through the meal-dispensing port. After detecting that the photoelectric switch is in the disconnected state, the cantilever is controlled to move the meal-taking platform to the preset point. Alternatively, the cantilever is controlled to move the meal-taking platform to the original position of the meal-taking platform, i.e., restore the meal-taking platform to its original position. The above preferred implementations can avoid the risk of the user's hand being pinched and ensure the safety of the user when using the smart meal cabinet.

[0050] After the user completes the purchase instruction at the smart meal cabinet, during the meal delivery process of the smart meal cabinet, if the cantilever moves the meal pickup platform away from the meal delivery platform due to the user's hand reaching out at the meal delivery port, the user will not be able to successfully pick up the purchased meal. Taking the above situation into consideration, this embodiment provides a preferred implementation method, that is, after the cantilever is controlled to move the meal pickup platform away from the meal delivery platform, it continues to detect the state of the photoelectric switch at the meal delivery port; if the photoelectric switch is always in the on state within the preset time, indicating that there is no obstruction at the meal delivery port, then the cantilever is controlled to push the meal pickup platform to the meal delivery platform, thereby successfully delivering the meal box to the meal delivery platform, making it convenient for the user to safely pick up the meal box, and the above purchase process ends. This avoids the user's inability to pick up the meal due to misoperation at the meal delivery port, avoids affecting the user's normal use of the smart meal cabinet, and also reduces the workload for manual after-sales service.

[0051] In addition to the above preferred implementations, after the control arm moves the meal-taking platform away from the meal-delivery platform, a prompt message can be sent to the user to prompt the user to send a new meal-delivery instruction; after receiving the new meal-delivery instruction, the control arm pushes the meal-taking platform to the meal-delivery platform. Based on this, the user can finally get the meal, avoiding the situation where the user cannot get the meal due to misoperation at the meal-delivery port.

[0052] Example 3

[0053] Figure 4 is a flow chart of a food serving control scheme for preventing hand pinching of a smart food cabinet according to an embodiment of the present invention. Figure 4 As shown, the process includes:

[0054] In the normal meal collection process, when the meal collection platform reaches the meal outlet, the conveyor wheel on the meal collection platform pushes the lunch box to the meal distribution platform. However, during the meal pushing process, it is possible that some users will reach into the meal outlet to directly take the meal before the meal is finished, which may cause hand pinching and the system to determine that the meal collection has failed. Therefore, a new control method has been developed. This algorithm cooperates with the photoelectric switch to automatically adjust the position of the meal collection cantilever and the meal collection platform to ensure that the meal can be pushed to the meal collection platform every time, avoiding hand pinching and the system to determine that the meal collection has failed. After the user completes the purchase, the cantilever will send the meal collection platform to the cargo aisle to pick up the meal. When the lunch box arrives at the meal collection platform, the cantilever will send the meal collection platform to the meal outlet, and the conveyor wheel on the meal collection platform will push the lunch box to the meal distribution platform. This solution makes judgments on two unexpected meal collection situations in the above process:

[0055] If the meal-taking platform has not yet reached the meal outlet, the conditions for taking the meal are not met. If the user reaches into the meal outlet, the photoelectric switch at the meal outlet will be blocked by the user's arm. At this time, the photoelectric switch is disconnected, and the cantilever returns the meal-taking platform with the meal box to the origin of the machine, thus avoiding the situation where the user's hand is caught between the platform and the meal outlet.

[0056] If the meal-taking platform has reached the meal outlet, it takes time T (e.g. T=5s) to push the lunch box to the meal-taking platform according to the setting. If the meal-taking platform does not detect a lunch box within 5s and the photoelectric switch is turned off, it is determined that a user reached out to forcibly take the meal while the lunch box was being sent from the meal-taking platform to the meal-delivery platform, ending the meal-taking process. The cantilever returns the meal-taking platform to the machine origin. If the meal-delivery platform detects a lunch box within 5s, it is determined that the meal is taken. After the meal is taken, the cantilever returns the meal-taking platform to the machine origin.

[0057] The algorithm can solve specific problems on site, and can solve problems simultaneously without additional human processing, greatly reducing human resources, reducing the accident rate, and improving product reliability. This embodiment solves the problem that users may get their hands caught when they pick up food in advance, and also solves the problem that the smart meal cabinet cannot recognize that the meal box has been taken out when users pick up food in advance, and also solves the problem that the system cannot settle the purchase process when users pick up food in advance.

[0058] The anti-pinch control scheme of the intelligent food cabinet in this embodiment can be achieved by adding a photoelectric sensor at the food delivery port, coordinating the controller signal sent by the food delivery cart to the food delivery platform and the newly added control algorithm, so as to ensure that when the food has not yet reached the food delivery platform, if the user reaches out to take the food, the movement trajectory of the cart is adjusted to prevent the pinching phenomenon. The above scheme improves the reliability of the product, enhances the user's food shopping experience and safety, and saves after-sales labor costs to a certain extent.
