and S7, judging that the non-connected equipment is in an off-line state according to the heartbeat timeout information.
Specifically, the normally connected device and the non-normally connected device in this embodiment both consider the internet of things fire fighting device to be on-line when the internet of things platform receives the message of the internet of things fire fighting device, rather than establishing connection to judge that the internet of things fire fighting device is on-line, thereby effectively avoiding misjudgment on the on-line of the device; entering subsequent logic for judging the offline of the Internet of things fire fighting equipment after the Internet of things fire fighting equipment is on line; when the offline judgment is carried out on the Internet of things fire fighting equipment, the Internet of things fire fighting equipment is considered to be offline when the connection of the equipment is disconnected by the frequently-connected equipment; and the equipment is connected very much, and after the heartbeat of the equipment is overtime, the Internet of things fire-fighting equipment is considered to be offline.
Preferably, the acquiring heartbeat timeout information of the very connected device includes:

s601, providing an installation interface for an application overtime callback function and a writing interface for writing data into the ordered linked list; wherein an application characterizes a timing application of a very connected device;
s602, when the data are inserted into the ordered linked list, the ordered linked list is controlled to be sorted according to the weight value of the inserted data;
s603, taking out the first 10 data of the ordered linked list every second at regular time, comparing the data with the millisecond number of the current time, and judging whether the time is out;
and S604, if the link table is overtime, calling an overtime callback function, and deleting the overtime data in the link table.
Preferably, referring to fig. 4, when controlling to insert data into the ordered linked list, the ordering of the ordered linked list according to the weight value of the inserted data includes:
s6021, controlling the data inserted into the ordered link list to be arranged in an ascending order according to the weight value;

The management program is as follows: providing an installation interface of a timed application overtime callback function of the non-connected equipment and an interface for writing data elements into the ordered linked list; the ordered linked list needs to ensure that the linked list can be sorted according to the weight values inserted when the data elements are inserted into the linked list every time, and the data elements in the linked list are arranged in an ascending order according to the weight values in the embodiment; because the ordered linked list is globally shared, a mutual exclusion lock is required to be added when the linked list is operated, and the mutual exclusion lock can be released overtime. Each data element in the ordered link list comprises two fields, namely a device ID of the non-connected device and the timing millisecond number of the non-connected device, wherein the timing millisecond number of the non-connected device plus the millisecond number of the current time is a weight value of ordered link list sequencing; the management program takes out the first 10 data elements of the ordered linked list every second at regular time and compares the data elements with the millisecond number of the current time to judge whether the time is overtime; if the time is out, calling a callback function of the time is out, wherein the parameters of the callback function are two fields of the equipment ID of the non-connected equipment and the millisecond number timed by the non-connected equipment, which are stored in the ordered chain table, and then deleting the elements of the time out in the chain table.
