if yes, sending self status data in a broadcasting mode,
if not, waiting for the data of the previous node, if the waiting data arrives, adding self state data on the basis of the received data, and then sending the data in a broadcasting way; if the waiting data does not arrive until the waiting time is exceeded, but the data before the previous node is received, adding self state data on the basis of the received data, and then sending the data in a broadcasting way; if the data of other nodes are not received until the waiting time is exceeded, the self state data is sent in a broadcasting mode;
until the data is transmitted to the data concentrator and transmitted to the data processing platform through the data concentrator.
3. The fire extinguisher management system based management method according to claim 1, wherein: if the nth node equipment fails, after receiving the state data sent by the (n + 1) th node equipment, the (n-1) th node equipment waits for more than the preset waiting time and does not receive the state data sent by the nth node equipment, then the (n-1) th node equipment adds the state data of the nth node equipment on the basis of the received data, sends the state data in a broadcasting mode, and marks the state of the nth node equipment in the sent data as a failure.
4. The fire extinguisher management system based management method according to claim 1, wherein: the wireless alarm device comprises:
a control chip;
the detection modules are connected with the control chip, respectively connected with the output end of a pressure gauge of the fire extinguisher and the sensor and used for acquiring detection information of the current wireless alarm device;
and the wireless module is connected with the control chip and used for receiving or sending data.
5. The fire extinguisher management system based management method according to claim 1, wherein: the metal swinging piece is provided with an arc-shaped groove, the base is correspondingly provided with a positioning pin shaft, and the positioning pin shaft is embedded in the arc-shaped groove.
6. The fire extinguisher management system-based management method according to claim 1, wherein: the hinged end of the pressure pointer is provided with a first conductive piece, the hinged end of the metal swinging piece is provided with a second conductive piece, and when the pressure pointer is contacted with the metal swinging piece, a loop is formed between the first conductive piece and the second conductive piece.
7. The fire extinguisher management system based management method according to claim 5, wherein: the ratio of the distance from the positioning pin shaft to the hinge shaft of the metal swinging piece to the distance from the hinge shaft of the metal swinging piece to the connecting point of the elastic piece is 14.
