s10, acquiring equipment state information, and splitting the equipment state information into N pieces of monitoring point information;
it should be noted that the device status information is composed of a series of monitoring point information, and the monitoring point information may be preset according to actual requirements, for example, the monitoring point information may include device monitoring point ID, monitoring point type, monitoring point status, monitoring point text, monitoring point fault threshold, monitoring point fault counter, and monitoring point update time.
The watchpoint ID is used to identify different watchpoints, and the watchpoint ID is globally unique. An exemplary watchpoint ID composition rule is given below:
the ID of the monitoring point can be set as a 32-bit unsigned integer, the lowest bit is represented by D0, the highest bit is represented by D31, the monitoring points are represented by D0-D7, the boards to which the monitoring points belong are represented by D8-D15, the combination to which the monitoring points belong is represented by D16-D23, and the system to which the monitoring points belong is represented by D24-D31.
The monitoring point types can comprise enumeration types and text types, for the monitoring points of the enumeration types, the state values of the monitoring points only depend on the states of the monitoring points, and the texts of the monitoring points are invalid; for a watchpoint of text type, its status value depends on both watchpoint status and watchpoint text values.
The monitoring point states can be classified as offline, fault, degraded and normal.
The monitoring point text is used for recording monitored data or texts needing description, such as voltage values or key actions of a working process.
When the monitoring point fault threshold indicates that a fault of a normal state monitoring point continuously occurs for a preset number of times, the monitoring point is considered to be a real fault and can be set according to actual requirements.
The monitoring point fault counter is used for recording the continuous fault times of the monitoring point;
the monitoring point update time is used for updating the time of the monitoring point information.
It should be understood that after the monitoring point information is set, numbers and numbers of the system, combination and board card to which the monitoring points belong can be allocated according to the monitoring point information.
For example, assume that there are two systems, numbered 1 and 2; the system 1 has 2 combinations, and the serial numbers are 1 and 2 respectively; the combination 1 is provided with 4 board cards with the numbers of 1,2, 3 and 4 respectively; the board card 1 has 5 monitoring points, and the numbers are 1,2, 3, 4 and 5 respectively.
According to the convention, the 16-system code of the monitoring point ID corresponding to the monitoring point 1 of the combination 1 board card 1 of the system 1 is 0x01010101. Similarly, the 16-system code of the monitoring point ID corresponding to the monitoring point 2 of the board 1 in combination 1 in the system 1 is 0x01010102. And other monitoring point ID codes are analogized, and are not described in detail.

it should be appreciated that the device status information may be split into multiple watchpoint information stores and device status management tables. The device status management table may manage device watchpoint information using a binary tree with watchpoint IDs as primary keys.
S31, if the ith monitoring point exists in the equipment state management table, judging whether the ith monitoring point has a fault according to the state of the monitoring point;
for example, if the information is analyzed according to the design convention, and the state of the monitoring point 1 of the board 1 of the combination 1 of the system 1 is analyzed, the monitoring point is 0x01010101. If the monitoring point 0x01010101 information exists, the node is judged to be in the equipment state management table, and whether the fault occurs is continuously judged according to the storage process.
Optionally, in some possible embodiments, the method further includes:
and S32, if the ith monitoring point does not exist in the equipment state management table, storing the monitoring point ID, the monitoring point state, the monitoring point text and the monitoring point type of the ith monitoring point in the equipment state management table by taking the monitoring point ID as a key value, and setting the received state as an initial state.
It should be understood that other information for the newly stored watchpoints, such as watchpoint fault thresholds and watchpoint fault counters, may follow the pre-set settings.

and S63, if the fault counter of the ith monitoring point is not greater than the fault threshold, only updating the updating time of the ith monitoring point in the equipment state management table, and not changing the state of the ith monitoring point.
It should be understood that the fault threshold may be set according to actual requirements, and may be 5, for example, when the number of fault states of the fault counter counts to 6, the fault is considered to have occurred at the monitoring point.
