However, this kind of power distribution room monitoring system adopts a uniform monitoring method. In the whole life cycle of power distribution room equipment and monitoring equipment, the characteristics of power distribution room equipment and monitoring equipment in different stages of operation are different.

Example 2

Referring to FIG. 1 and FIG. 2 , this embodiment discloses a method for monitoring the full life cycle of a power distribution room, using the full life cycle monitoring system for a power distribution room in Embodiment 1, including the following steps:

S1: Get device runtime

In a monitoring period T, the number of times that equipment inspection obtains data from the equipment status monitoring system 3 and the environmental parameter monitoring system 4 is N; the unit of T is minutes, and the unit of N is times;

The main control terminal 2 retrieves the timing data of the system runtime detection unit 6;

When the timing data _t≤Tpre1 of the system running time detection unit 6, in a monitoring period T, N is n, and _Tpre1 is the artificially set minimum buffer time for the operation of the newly purchased equipment; _Tpre1 can be 3 moon;

When the timing data _Tpre2 <t< _Tpre1 of the system running time detection unit 6, in a monitoring period T, N is n ₀ , and _Tpre2 is the highest buffer time for the operation of the newly purchased equipment manually set; _{Tpre2 1} can be 36 months;

When the timing data t≥Tpre ₂ of the system running time detection unit 6, in a monitoring period T, N is n', and both n and n' are artificially set, which are positive integers and n'>n ₀ >n ;

S2: Device Status Inspection

In a monitoring period T, a monitoring count factor X is preset, the initial value of X is zero, and X is a positive integer;

When X≤N, perform the following steps:

S2.1: Monitor the operating state of the equipment through the sulfur hexafluoride sensor 301, the noise sensor 302, the partial discharge sensor 303, the ozone sensor 304 and the oxygen sensor 305 in the equipment state monitoring system 3, and the sulfur hexafluoride sensor 301. The monitoring data packets _AX obtained by the noise sensor 302, the partial discharge sensor 303, the ozone sensor 304 and the oxygen sensor 305 are sent to the main control terminal 2, where _AX is A ₁ , A ₂ , . . . , A _N ;

S2.2: Monitor the operating environment state of the equipment through the temperature sensor 401, humidity sensor 402, smoke sensor 403 and water immersion sensor 404 in the environmental parameter monitoring system 4, and monitor the temperature sensor 401, humidity sensor 402, smoke sensor 403 And the monitoring data packet B _X obtained by the water immersion sensor 404 is sent to the main control terminal 2, where B _X is B ₁ , B ₂ , . . . , B _N ;

S2.3: X is automatically accumulated and added by one, and the loop enters step S2;

When X>N, X is cleared, and exit step S2;

S3: Status Signal Abnormal Judgment Processing

An abnormal signal indication value Y is preset, and the initial value of Y is 0;

When the main control terminal 2 compares the received monitoring data packets _AX with the preset normal range values stored in the main control terminal 2 one by one, the preset normal range values are manually set and stored in the main control terminal 2. If When an abnormal monitoring signal occurs in Ax:

If t< _Tpre1 , then execute S3.1.1; if _Tpre2 <t< _Tpre1 , execute S3.1.2, if _t≥Tpre1 , otherwise execute S3.1.3;

S3.1: If Y=0, set Y=1; and wait for a preset delay time T', T' is artificially set, which can be 1 to 15 minutes, enter step S2, and obtain the equipment status of the next cycle The monitoring data package A' _X of the monitoring system 3 and the monitoring data package B' _X of the environmental parameter monitoring system 4 and the information of the video surveillance system;

If Y=1, then make Y=0, and judge whether the monitoring data of the equipment status monitoring system 3 and the monitoring of the environmental parameter monitoring system 4 and the information of the video monitoring system are abnormal:

If more than one of the monitoring data of the equipment condition monitoring system 3 or the monitoring of the environmental parameter monitoring system 4 or the information of the video monitoring system is abnormal, then execute S4;

Otherwise, the main control terminal 2 outputs the indication signal of the normal operation of the device;

S3.2: Compare the monitoring data packets B _X received by the main control terminal 2 with the monitoring data packets B" _X received in the previous cycle one by one, and retrieve the monitoring information of the video monitoring system, if B _X and B ” If the coincidence degree of _X is high and the video surveillance system is normal, the main control terminal 2 outputs an indication signal that the equipment is running normally;

Otherwise, execute S4;

The high degree of coincidence of data means: taking a temperature sensor as an example, if the output temperature range of the previous cycle is 25-28°C, the output temperature range of this cycle is 34-36°C, which is abnormal, and the output temperature of this cycle is 27-30°C. That is to say, the fluctuation of the two-cycle monitoring data of each sensor should not be large. Even if 27-30 °C is still within the allowable temperature range, due to the large temperature difference in a short period of time, the equipment may experience abnormal temperature rise, etc., so it is necessary to combine video monitoring. The system is verified, and only when the environmental monitoring data and the video monitoring system are normal, the main control terminal outputs a signal that the equipment is operating normally.

Similar to other sensors, it should be comprehensively judged based on factors such as the reliability of equipment data, the required security of the equipment, the specific installation location, and the environment.

S3.3: execute S4;

S4: The main control terminal 2 transmits the abnormal information to the power distribution room monitoring center 1, and repairs and replaces the abnormal equipment or abnormal monitoring system in time.

The sending of the indication signal of the main control terminal 2 can be indicated by sound, light or display, such as voice broadcast, indicator display or the words "system is running normally" displayed on the screen.

For step S3.1.2, since this situation is t≥T _{pre 2} , that is, the running time of the monitoring system exceeds the artificially set maximum buffer time T _{pre 2} for the operation of newly purchased equipment, and T _{pre 2} is, for example, 3 months, then the main The control terminal 2 has passed the unstable operation state T _{pre 1} and has exceeded the artificially set maximum buffer time T _{pre 2} for the operation of the newly purchased equipment, and enters the aging state, and a large amount of monitoring system data is stored. Therefore, the main control The terminal 2 pre-stores the monitoring data packets A” _X and B” _X of the previous cycle, and there is no situation that the monitoring program cannot run normally due to the absence of the monitoring data packets A” _X and B” _X of the previous cycle.

Therefore, through the above monitoring method, for the newly purchased monitoring equipment, when the operation is unstable, that is, when t<T _pre1 , the newly purchased monitoring equipment will be short-term due to problems such as installation, debugging and environmental matching. During the period (several months), there is a high monitoring error rate. At this time, if the abnormality of the power distribution room is monitored and the maintenance is rashly carried out, it will cause unnecessary losses.

At this time, after the data monitored by the first group of equipment state monitoring system 3 is transmitted to the main control terminal 2, if it indicates that the equipment is in an abnormal state, the information will be idle first, and the equipment state judgment will not be performed. Delay for a few minutes to obtain the second set of equipment status monitoring data. If more than one of the monitoring data of the equipment status monitoring system 3 or the monitoring of the environmental parameter monitoring system 4 or the information of the video monitoring system is abnormal, the abnormal information will be transmitted to the monitoring system. In the center, the monitoring center combines the video monitoring system to verify the source of the abnormal state of the equipment, and repair and replace the abnormal equipment or abnormal monitoring system in time.

For the monitoring equipment that has passed the long-term stability period and is aging, the monitoring effect is greatly reduced due to the aging of the monitoring equipment in the later stage of operation of the power distribution room. If the equipment is not replaced, the monitoring system of the power distribution room is prone to failure and missed reports Case. If the operation plan is not changed, the power distribution room may cause heavy losses due to failure to monitor the fault.

At this time, the monitoring frequency of the equipment state monitoring system 3 is increased, the amount of information data of the power distribution room obtained is increased, and the number of information for judging the state of the power distribution room is increased.

When it is found that the equipment detection data or environmental detection data or video monitoring results are abnormal during the monitoring period, maintenance and processing shall be carried out immediately;

However, before the equipment has passed the minimum buffer time and has not entered aging, that is, T _pre2 < t < T _pre1 , after the information monitored by the equipment status monitoring system 3 is transmitted to the main control terminal 2, it will be first and the previous monitoring period. Compare the monitoring information inside, if the two show a high degree of coincidence, it proves that the overall operation of the equipment is stable.

If the monitoring results of the two are inconsistent, it will first judge the difference in the monitoring results of the environmental parameter monitoring system 4 in the same monitoring period and retrieve the video monitoring information. If the monitoring results of the environmental parameter monitoring system are still different or the video monitoring information is abnormal, the information will be transmitted. Go to the monitoring center to remind the power distribution room that there is an abnormality and need maintenance;

However, if the monitoring results of the environmental parameter monitoring system are normal and the video monitoring information is normal, it is determined that the power distribution room is in a normal operating state.

In this way, the monitoring of the running time of the monitoring system is increased, and the monitoring scheme of the power distribution room is adjusted according to the monitoring system of different stages of use, so as to reliably monitor the status of the power distribution room and reduce the use of a single monitoring scheme. This leads to over-monitoring or omission of power distribution methods.
