[0076] The specific steps of the railway power distribution substation operation and maintenance management system are as follows:

[0077] Step 1: Architecture Setup: The terminal integration module integrates the terminal equipment in the monitoring room, and the application integration module integrates the monitoring and inspection equipment on the railway side. Then, the application add / delete module connects the railway-side equipment to the intelligent operation and maintenance system or deletes the railway-side equipment from the intelligent operation and maintenance system, completing the setup of the terminal unit and the application unit. Subsequently, the wireless transceiver module receives the data collected by the railway-side equipment in the application unit and sends control commands to the railway-side equipment to control the railway-side equipment to operate according to the control commands. After the information transcoding module performs digital-to-analog conversion, the visualization module displays the converted data in the terminal unit in the form of pictures or tables.

[0078] Step 2, Inspection Settings: The inspection settings module sets the inspection route and inspection method for the inspection equipment in the application unit. The standard recording module sets the data collected by the inspection equipment when it is working normally on the inspection route as the standard data for normal operation. The comparison and analysis module compares and analyzes the data collected by the inspection equipment on the inspection route with the standard data on the corresponding inspection route. When the data exceeds or falls below the standard data, the anomaly marking module marks the location as an anomaly, which is then used by the terminal unit for inspection. This allows management personnel to make on-site judgments and achieve rapid fault detection and location.

[0079] Step 3: Alarm Setting: The threshold setting module sets the alarm thresholds for data collected by the monitoring and inspection devices in the application unit. The application unit includes n monitoring devices and n inspection devices. The n monitoring devices are set at equal intervals along the inspection route.

[0081] Alarm triggering module 1 is used to compare the result of the comparison between the data collected by the monitoring and inspection equipment in the application unit and the alarm triggering value θ, and send a signal to the terminal unit based on the comparison result.

[0082] The alarm signal determination method of the alarm triggering module is as follows:

[0083] Let β i Let β be the measured value of the intermediate device among three adjacent monitoring devices. i-1 β is the measurement value from the previous device. i+1 For the measurement value of the next device;

[0084] Let γ i Let γ be the measured value of the intermediate device among three adjacent inspection points. i-1 γ is the measured value of the previous inspection point. i+1 The measurement value for the next inspection point;

[0085] Let P be the ratio of the measured values ​​from the monitoring equipment to those from the inspection equipment, then:

[0086] P i-1 =β i-1 / β i

[0087] P' i-1 =γ i-1 / γ i

[0088] P' i =γ i / γ i+1

[0089] P' i+1 =γ i-1 / γ i+1

[0090] when:

[0091] |P i-1 -P' i-1 |+|P i+1 -P' i+1 |>θ

[0092] The fault point is determined to be located at the (i-1)th monitoring point;

[0093] when:

[0094] |P i-1 -P' i-1 |+|P i -P' i |>θ

[0095] Determine that the fault occurs at the i-th monitoring point;

[0096] when:

[0097] |P i+1 -P' i+1 |+|P i -P' i |>θ-1

[0098] The fault point is determined to be located at the (i+1)th monitoring point;

[0099] Where θ is the alarm trigger value.

[0100] Step 4, Alarm Feedback: The alarm limitation module sets the alarm feedback time limit and establishes an identity docking channel between terminal unit administrators and the intelligent operation and maintenance system. When an alarm occurs, the terminal unit administrators act as the alarm feedback channel. The response trigger module is used to trigger an emergency contact instruction when the alarm feedback exceeds the time limit. The emergency contact instruction is sent to the emergency contact module. The emergency contact module sets the superior of the terminal unit administrator as the emergency contact person. Upon receiving the emergency contact instruction, it contacts the set emergency contact person and issues an alarm.
