Problems solved by technology

[0003] First: Due to the requirements of real-time detection of baking, the communication frames of the detection nature between the client and the detection module are sent very frequently. Due to problems such as the network environment, there will be situations where multiple communication frames are accumulated in a queue. If this When the client sends baking-related control commands, the control frame will be added to the end of the queue, and the commands will not be sent to the control module for control at the first time.
This will reduce the real-time performance of the control, bring errors to the baking control, and affect the judgment of the baker. At the same time, if the priority queue is simply used for optimization, if the client has an abnormal operation or the network environment is abnormal, the normal temperature frame will also be normal. A variety of control frames will be accumulated. However, the effectiveness of the control frames no longer exists at this time. In order to ensure the continuity of the baking temperature, the latest temperature detection frame should be sent at this time to detect the temperature.
If the traditional method of sending frames is used, the accuracy of coffee roasting control cannot be guaranteed
[0004] Second: Based on the habit of programming operations on the client side, it is often required that each command can have a corresponding command, while the traditional Socket communication method can only be guaranteed at the connection level, and cannot be accurate enough that the sending and replying of each command corresponds to each other.

Embodiment Construction

[0018] In order to make the purpose, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 The overall frame diagram is shown. Different from the traditional roaster, the present invention is based on the control process of the Internet of Things, including the client, the WIFI control module and the coffee roaster entity. The user sends commands to the WIFI control module through the client, and the control module controls the relay to operate the coffee roaster for related operations. At the same time, the client is also responsible for obtaining the collected data from the WIFI module. Integrate data. The coffee roaster controller and the client are connected in the same local area network, using wifi wireless, and both are connected under the same wireless router in STA mode. In the same LAN, th...

Abstract

The invention discloses a socket-based coffee roasting communication method. Aiming at the demand of communication command priority, a frame data priority part is designed and added. In order that each command can pass through the corresponding communication process, a frame data unique code mechanism is added; in order to be adaptive to the characteristic of very frequent temperature monitoring during the coffee roasting process, an optimization mechanism for communication under a special condition when a command is blocked is designed; by means of the characteristic of priority queue, high priority is set for a control command of coffee roasting, low priority is set for temperature monitoring, and the real-time performance of control is ensured; and meanwhile, the time of last temperature detection is recorded in the communication mechanism at any time, and a dynamic priority-revised mechanism is provided for a scene with high demand on temperature reading smoothness.

Description

technical field [0001] The invention relates to the technical field of communication in the Internet of Things, in particular to a communication method and protocol design for a roasting process of a coffee roaster. Background technique [0002] In the coffee roaster Internet of Things control method, the client uses socket-based control to send information to the embedded control module installed in the roaster. The control module parses the corresponding frame and performs corresponding processing according to the frame protocol agreement. The embedded module communicates with the customer end to achieve duplex communication. The general method of processing commands on the client side is to put the commands in the queue and send the commands according to the enqueue time. At the same time, when the embedded module returns the reply frame, it returns in the same order without any difference. This traditional communication method has the following problems in the roasting ...
