Description

Technical Field The present invention relates to an IoT system and a control method therefor. Background Art IoT (Internet of Things) is increasingly common in production and life nowadays. People may use smart phones, tablet computers and other electronic devices to establish a network connection with a production or everyday tool, and monitor and control the tool by means of the electronic device, so as to be able to know information of the tool, such as operating state, in a timely manner. Generally, a wireless power supply mode for battery pack power supply and a networking mode of wireless network connections are used, to reduce space restrictions entailed by wired power supply and networking modes. However, each tool being equipped with a wireless communication module also produces a problem of increased costs. Therefore, a common battery pack is provided for different tools, and a wireless communication module is arranged on the battery pack, so that an electronic device establishes a network connection with the tools by means of the battery pack. However, when the tools operate for a long time, and it is necessary to frequently replace the battery pack, each time the battery pack is replaced, it is necessary to re-establish a network connection for the electronic device and tools, with the result that operation is more cumbersome. Therefore, it is necessary to provide an IoT and control method therefor to mitigate the above problem. Summary of the Invention An object of the present invention lies in providing an IoT system and control method therefor, with an electronic device in said system, by means of a frequently replaced battery pack, automatically wirelessly connecting to a terminal device connected to the battery pack, and it is thus possible to reduce unnecessary and cumbersome connecting operations by a user, providing convenience for controlling an IoT. According to one aspect of the present invention, the IoT system comprises: a battery pack, the battery pack being provided with a connecting terminal and a wireless communication module, the battery pack being configured to be capable of establishing an electrical connection and communication connection with a terminal device by means of the connecting terminal, and to be capable of issuing broadcast information by means of the wireless communication module, the broadcast information comprising identity information of the terminal device connected to the battery pack; andan electronic device, the electronic device being configured to be capable of receiving the broadcast information, and to be capable of operably establishing a wireless connection with the battery pack,wherein the electronic device is further configured to be capable, in a state of having established a wireless connection, of storing identity information of the terminal device, and in a state of the wireless connection being broken, on the basis of the identity information in received said broadcast information matching the stored identity information, automatically establishes a wireless connection with the battery pack which issues the broadcast information. In some embodiments, the battery pack is further configured such that a wireless connection between the battery pack and the electronic device is broken at the same time as a connection between the battery pack and the terminal device is broken. In some embodiments, the electronic device is further configured to be capable, on the basis of a user operation, of breaking, from the electronic device side, a wireless connection with the battery pack. In some embodiments, the electronic device is further configured such that, when a wireless connection with the battery pack is broken on the basis of the user operation, identity information of the terminal device associated with the disconnected battery pack is deleted in the stored information of the electronic device. In some embodiments, the electronic device is further configured to be capable of establishing a wireless connection with the battery pack, on the basis of a user operation, when the identity information in received said broadcast information does not match the stored identity information. In some embodiments, the identity information comprises an ID or MAC address of the terminal device. In some embodiments, the broadcast information further comprises state information of the terminal device connected to the battery pack, and/or the broadcast information further comprises identity information and/or state information of the battery pack.
