Please refer to fig. 1 to 3:
as shown in fig. 1, the present invention provides a remote fire fighting method, comprising:
the fire control host receives alarm information and fault information sent by alarm equipment;
the fire control host encapsulates the alarm information and the fault information into a first data packet and sends the first data packet to a controller;
the controller forwards the first data packet to a printer;
the controller analyzes the first data packet to obtain an analysis result;
the controller encapsulates the analysis result and the MAC address of the controller into a second data packet;
the controller sends the second data packet to a cloud server.
Further, before sending the first data packet to the controller, the method further includes:
the controller judges whether the printer is in an idle state;
if so, the controller informs the fire control host computer to send the first data packet;
otherwise, starting timing to obtain waiting time; if the waiting time exceeds a threshold value, the controller informs the fire control host computer to send the first data packet; otherwise, continuing to count time.
As can be seen from the above description, when the printer is in the busy state, the first data packet is suspended from being sent, so as to avoid information blocking; the controller adds a timing function when detecting the state of the printer, and directly sends the first data packet if the printer is still in a busy state within a specified time, no matter whether the printer can receive the first data packet, so that the aim of ensuring that the printing information can be timely processed and uploaded to the cloud server when the printer breaks down is achieved.
Further, the controller analyzes the first data packet to obtain an analysis result, specifically:
analyzing the first data packet to obtain an event set;
identifying a dot matrix in the event set to obtain event specific information; the event specific information comprises an event type and a channel number;
and packaging the event specific information into an analysis result.
As can be seen from the above description, the alarm type can be obtained by matching the lattice of the event set in the first data packet with the preset lattice of the chinese character, for example, the alarm type may be "fire alarm", "standby power failure", "main power failure", and "address failure", etc.; and matching the dot matrix of the event set in the first data packet with a preset digital dot matrix to obtain the channel number.
Further, the controller analyzes the first data packet to obtain an analysis result, specifically:
analyzing the first data packet to obtain an event set;
identifying a dot matrix in the event set to obtain an event type;
identifying ASCII codes in the event set to obtain a channel number;
and packaging the event type and the channel number into an analysis result.
As can be seen from the above description, the fire fighting control host can also use ASCII code to represent channel number, and can find out the location of the fire fighting equipment in the building by looking up ASCII characters of the channel number in the first data packet and calculating; for example, channel number "087": three consecutive hexadecimal character data "0 x 30", "0 x 38" and "0 x 37", which represent ASCII characters "0", "8" and "7", respectively, are obtained from the first packet, and since we need to be channel number values, the calculation method is as follows:
channel number (0x30-0x30) × 100+ (0x38-0x30) × 10+ (0x37-0x30) × 1 ═ 87.
Further, after the controller sends the second data packet to the cloud server, the method further includes:
the cloud server analyzes the second data packet to obtain an event type, an MAC address and a channel number of the controller;
the cloud server searches a building address corresponding to the MAC address of the controller in a controller information table; the controller information table stores the basic information of the controller, including the MAC address of the controller and the building address where the controller is located;
the cloud server searches the position of the fire fighting equipment corresponding to the channel number in the building in a channel information table; the channel information table stores basic information of the fire fighting equipment, including the positions of the fire fighting equipment in the building;

linking the corresponding plane graph according to the position information;
acquiring the real-time situation of the defense eliminating equipment on the plan;
and linking video previewing or recording around the position information according to the position information.
According to the description, the cloud server can analyze the data packet sent by the controller, know the type of the accident, the building address and the specific position of the accident occurrence point in the building, and send the data packet to the terminals of the related personnel, so that the related personnel can obtain the accident related information at the first time, comprehensively prepare for related rescue, and arrive at the site at the first time to carry out rescue work.
