Referring to fig. 1, fig. 1 is a diagram illustrating a location detection method based on the internet of things according to an embodiment of the present invention. As shown in fig. 1, a location detection method based on the internet of things according to an embodiment of the present invention includes the following steps:
s101, a controller sends geographical position request information to each safety helmet, wherein the geographical position request information is used for indicating each safety helmet to feed back the current geographical position;
there are many ways of representing the geographical position, such as coordinates, e.g. pictures.
For example, if the helmet receives the geographical location request message sent by the controller, the camera device is started to take a picture of the surrounding environment, and then the taken picture is sent to the controller. Optionally, the helmet may identify the picture taken (e.g., match the building inside the picture with a picture of a preset building) to determine the current geographic location.
For example, if the helmet receives a geographic location request message from the controller, the positioning system may be activated to determine the current geographic location.
Wherein, it can be understood that when the safety helmet receives the geographical position request position information sent by the controller, the safety helmet can prompt the user for position feedback. For example, the user may be prompted by voice, for example, the user is prompted to click a reporting button to report the geographic location; for example, the user is prompted to enter a fingerprint, and when the entered fingerprint matches a pre-stored fingerprint, a geographic location reporting device (e.g., satellite positioning or photographing) is activated.
Optionally, before the controller sends the geographic position request information to each safety helmet, the use authority of each user carrying the safety helmet needs to be verified;
specifically, the verification method includes: the controller receives safety helmet starting requests sent by all safety helmets; wherein, the request comprises a user identification input by a user; the controller determines whether the user has the use authority of the safety helmet according to the identification information of the user; when the user is determined to meet the use authority of the safety helmet, the controller sends a starting instruction to the safety helmet meeting the use authority.

Optionally, the method further includes: when the current time is determined to be the working time period, the controller sends post checking information to each safety helmet; the controller receives geographical position information fed back by each safety helmet; and the controller determines whether an engineer carrying each safety helmet is on duty or not according to the geographical position information fed back by each safety helmet.
It will be appreciated that if the number of safety helmets exceeds a preset threshold, the safety helmets may be grouped; each group has a safety helmet as a gathering point, the controller sends the post-checking information to the gathering point, and the safety helmet of the gathering point forwards the post-checking information to other safety helmets of the group. If the collection point headgear can be determined based on signal strength. And setting the safety helmet with the strongest signal in each group as a gathering point. Of course, the CPU may also be configured to determine the configuration parameters, such as setting the safety helmet with the highest CPU frequency as the collection point of each group.
For example, there are 100 safety helmets, and the safety helmets can be divided into 10 groups, each group having 10 safety helmets, and one safety helmet is selected from each group as a collection point.
Wherein optionally, heartbeat information may be periodically sent to the headgear to determine the status of the headgear.
Specifically, the method further comprises: the controller acquires the identification of each safety helmet from the safety helmet management table; the controller sends heartbeat information to each safety helmet according to the identification of each safety helmet so as to determine whether each safety helmet is in an activated state; when the sensor in the dormant state is detected to exist, acquiring the service time of the helmet in the dormant state; when the service time of the sensor in the dormant state is longer than a preset time, the controller determines that the battery of the sensor in the dormant state is exhausted; the controller sends a prompt to the user to enable the user to perform battery replacement on the safety helmet in the dormant state.
