Fig. 1 is a flowchart illustrating steps of an unlocking control method for an incubator according to the present invention. As shown in fig. 1, the unlocking control method of the incubator of the present invention includes the following steps:
and step S1, acquiring the two-dimension code of food delivery/pickup by using the unlocking interface, and receiving an unlocking request of the user terminal.
In the specific embodiment of the present invention, taking meal fetching as an example, after the user successfully orders the meal through the meal ordering system, the user can obtain a meal fetching two-dimensional code through the meal ordering system, and in the specific embodiment of the present invention, the meal fetching two-dimensional code is encrypted, and includes at least four parameters: the box ID, the order number, the supply time period, and the encryption key are well known in the art and are not described herein. Specifically, when a user obtains the meal taking two-dimensional code and gets a meal from a corresponding insulation can, the meal taking two-dimensional code is first shown, the unlocking interface reads the meal taking two-dimensional code through a two-dimensional code reader on the insulation can, and an unlocking request is received.
And step S2, after the two-dimensional code for sending/fetching food is successfully verified, obtaining unlocking parameters according to the two-dimensional code for sending/fetching food, and verifying whether the unlocking parameters are correct or not on the food ordering platform.
Specifically, after the meal taking two-dimensional code is obtained, data information in the meal taking two-dimensional code is analyzed, the meal taking two-dimensional code is verified, unlocking parameters are obtained according to the data information of the meal taking two-dimensional code after the meal taking two-dimensional code passes verification, and whether the unlocking parameters are correct or not is verified to a database of a meal ordering platform through the unlocking parameters. That is, the detailed information of each order is stored in the database of the meal ordering platform, and after the unlocking parameters are obtained, whether the unlocking parameters are correct or not can be verified from the database of the meal ordering platform.
And step S3, when the unlocking parameters are verified to be correct, connecting the MQTT server, assembling and publishing the theme and the message according to the unlocking parameters, and sending an unlocking request to the MQTT server.
In the specific embodiment of the invention, the communication of software and hardware is completed through an MQTT server, according to the MQTT server, firstly a subscription theme is required to be configured, namely, a published theme and a message are assembled according to unlocking parameters, secondly, an unlocking request is sent to the MQTT server by a software layer during unlocking, and then the MQTT server forwards the unlocking request to a cabinet lock terminal to complete unlocking and feedback, wherein the unlocking request comprises the published theme and the message, for example, the unlocking parameters are No. 9 cabinet in 8 area and No. 2 cabinet, and then the message theme is as follows: the "unlock/8/9" message content is: 2, the message topic is 2 lock of the open 8-zone 9-cabinet.
Preferably, the lock hole plate of the cabinet lock terminal uses a data transmission format of byte stream data transmission, so decimal data of message content needs to be converted into binary data, and then the binary data is sent to the MQTT server through an unlocking request. Specifically, the conversion step is as follows;
step 1, initializing binary box IDs (for example, logic left shift acquisition) represented by integer, wherein in the specific embodiment of the invention, each cabinet has 16 boxes, and each box ID corresponds to the number of 16 boxes one by one; for example:
the first cabinet corresponds to: 1
The second cabinet corresponds to: 10
The third cabinet corresponds to: 100, moving left in sequence;
and 2, converting the obtained integer into a binary character string B, and adding the high-order 0 of the binary character string B. In the embodiment of the present invention, if the message content is number 2 lock, the initialization integer is 10, and the message content is converted into binary character string B of 0000-;
step 3, dividing the character string B into 4 sub-strings, and converting the sub-strings into corresponding hexadecimal representation, for example, obtaining the hexadecimal 0020 for the character string B;
step 4, converting the high and low bits into byte array, namely converting the high and low bits of 0002 into 0200, and sending the result to the opposite side
Preferably, if the current message content includes a plurality of box IDs, the initial shaping representation is performed on each box ID in step 1, and before step 2, the method includes the following steps:
and (3) performing OR operation addition shaping A according to the obtained plurality of shaping types and corresponding box IDs in sequence, and then entering the step 2.
That is, assuming that there are multiple boxes to be opened by the user, the message content of the multiple boxes includes 2,3,12, and 15 locks of the 8-block 9-size cabinet, i.e., {2,3,12, and 15}, where the box numbers are integer, i.e., the user wants to open four boxes at a time, normally needs to send four requests, respectively, i.e., needs to issue and assemble an unlocking request for each box. However, the present invention is expected to be able to open the four cabinets only by sending a command to the hardware, so the present invention first converts the cabinets No. 2,3,12,15 into binary representations of corresponding box numbers, respectively, and then performs an or operation to obtain the binary representations of the boxes No. 2,3,12,15 which are opened simultaneously: 0100100000000110, the application layer only needs to send a command to control opening several boxes at the same time, and does not need to issue and assemble an unlocking request for each box.
And step S4, after receiving the unlocking request, the MQTT server forwards the unlocking request to the cabinet lock terminal, and the cabinet lock terminal completes unlocking and feedback.
Specifically, step S4 further includes:
s400, the MQTT server forwards the theme A and the message B to a cabinet lock terminal according to the unlocking request;
step S401, the cabinet lock terminal judges whether a lock hole plate subscribed with a theme A exists;
and step S402, if yes, controlling the lock hole plate processing message B subscribed with the theme A to execute unlocking, otherwise, ending the process.
