Description

Wireless temperature probe, communication method thereof, cooking equipment and cooking system Technical Field The application relates to the technical field of temperature monitoring, in particular to a wireless temperature probe, a communication method thereof, cooking equipment and a cooking system. Background In fine cooking (e.g., baking, slow baking, low temperature cooking), it is important to monitor the core temperature of the food material in real time. The wireless temperature probe can be widely applied because of being capable of inserting the probe into the food, and sending temperature data to cooking equipment (such as an oven and a steaming and baking integrated machine) in a wireless mode, so that a user can grasp the cooking state without opening an equipment door. However, conventional wireless temperature probes based on the standard Bluetooth Low Energy (BLE) protocol have significant drawbacks in practical use. Specifically, the probe needs to broadcast periodically on three fixed broadcast channels (typically 37, 38, 39 channels), and after the cooking device is powered on, the probe must be found and connected to all three preset channels in turn. This full channel scanning procedure inevitably leads to significant first packet transmission delay, so that the cooking apparatus has a temperature monitoring blank period in the initial stage of starting, and the risk of overheating food materials or uncontrolled cooking is increased. Meanwhile, in order to maintain connection, the probe needs to continuously broadcast and wake up in a broadcast gap to receive link management information, so that the overall power consumption of the probe is high, the duration of the built-in micro battery is short, and the user experience is poor. The prior art attempts to balance power consumption with response speed by optimizing broadcast intervals, connection parameters, etc. However, these optimizations remain limited to within the standard broadcast/scan/connect framework, and do not fundamentally eliminate the initial delay caused by the device having to scan all channels, nor the bi-directional communication overhead of the probe to maintain the connection. In addition, in a complex wireless environment, the anti-interference capability of a communication mode of a fixed channel is weak, and the communication reliability is affected. Disclosure of Invention The application provides a wireless temperature probe, a communication method thereof, cooking equipment and a cooking system, and aims to solve the technical problems of blank period and first packet data transmission delay in temperature monitoring caused by scanning all channels of the conventional wireless temperature probe before connection with the cooking equipment is established and high power consumption caused by continuously broadcasting and receiving data. In a first aspect, an embodiment of the present application provides a wireless temperature probe, including: the temperature detection module is used for acquiring temperature data; the processor is connected with the temperature detection module and is used for processing the temperature data; a wireless communication module, coupled to the processor, configured to broadcast a signal comprising identification information and the temperature data on a first logical channel in a first mode of operation after power-up of the wireless temperature probe and at least until a communication link with a target device different from the first logical channel is established; Wherein the first logical channel is preconfigured by the processor and is composed of at least two physical broadcast frequency bands specified in a predefined frequency band range. In some embodiments, the wireless communication module is configured to be capable of broadcasting only signals and not receiving signals transmitted by the target device in the first mode of operation. In some embodiments, the first logical channel has a spacing between center frequencies of respective physical broadcast bands of at least 24MHz; and/or, the bandwidth of the physical broadcast frequency band is not less than 2MHz. In some embodiments, the predefined frequency band range includes one or more of 902MHz to 928MHz, 2400MHz to 2480MHz, and 5725MHz to 5850 MHz. In some embodiments, when the predefined frequency range is 2400MHz to 2480MHz, the physical broadcast frequency band constituting the first logical channel includes three physical broadcast frequency bands having center frequencies of 2402MHz, 2426MHz and 2480MHz, respectively. In some embodiments, the wireless communication module is further configured to selectively switch to the second operation mode to receive data sent by the target device under a communication protocol and frequency band different from the first logical channel after the wireless communication link is successfully established with the target device.
