Smart remote inspection and maintenance
Mine diesel generatorSmart remote inspectionMaintenance
For remote mining areas and long-term spontaneous power generation sites, engineers use controller data, ATS switching records, low-voltage distribution status, operating hours, load changes, alarm codes and on-site photos and videos to determine whether the shutdown risk comes from the unit body, power distribution system, load impact or maintenance gap.

Monitoring equipment and data collection points
Smart inspection equipment list: from unit data to on-site video
Smart inspection is not just a camera, but connects the generator controller, ATS, low-voltage power distribution, fuel, on-site environment and engineer services.
There is currently no remote module
Screenshots of controllers, photos of low-voltage cabinets, ATS status, inspection videos and maintenance records can still be submitted periodically on site to form remote inspection data.

Engineering judgment logic
The remote engineer does not just look at the alarm code, but makes a step-by-step judgment based on the risk level.
The same high temperature, trip or start failure alarm has different processing priorities in the drainage pump power supply, crushing line startup, parallel operation and long-term spontaneous power generation sites. Engineers will first judge production risks and then judge technical reasons.
First determine whether it affects critical loads
If drainage, crushing, ventilation, communications and camp power supply have been affected, engineers will give priority to temporary operation, load switching or load reduction observation suggestions.
Distinguish between the unit itself and external systems
High temperature, low oil pressure, and difficulty in starting are mostly related to the engine, maintenance, and fuel; voltage frequency fluctuations, tripping, and ATS switching failures are mostly related to power distribution, load impact, or protection settings.
Look at trends, not just single alarms
Under the same load, the water temperature continues to rise, the oil pressure gradually decreases, the load rate is high for a long time, and the alarm occurs repeatedly, which can better illustrate the direction of the problem than a single screenshot.
Judge maintenance and spare parts based on operating hours
When the operating hours are close to the maintenance window, or when alarms related to filters, belts, batteries, sensors, AVRs, and controllers increase, maintenance and spare parts recommendations will be given in advance.
Decide on remote guidance, spare parts preparation or on-site service
It is not necessary to dispatch personnel immediately every time an alarm is called, nor is it left to the scene to deal with it blindly. Engineers judge remote guidance, load reduction observation, spare parts preparation or arrange on-site services based on the risk level.
Service Team
Remote inspection is not a software entry, but a collaborative judgment by a group of engineers
What remote mining areas really need is someone who can understand the data and on-site photos, and can also push the problem to local inspection, factory technical review and spare parts confirmation.
Remote Engineer
Check the controller data, alarm codes, operating hours, load changes, photos and videos to determine the direction of the problem first.
Ecuadorian local engineer
Assist in on-site inspection, basic troubleshooting, installation and maintenance problem confirmation when necessary.
Factory technical support
When involving engines, generators, controllers, ATS, parallel machines or power distribution configurations, return to the factory data for review.
Spare parts support staff
Check spare parts, replacement parts and procurement cycles based on models, serial numbers, photos of old parts and fault symptoms.
Customer field team
Provide operating data, on-site photos and videos, load changes, operation records and executable scope.
What does the customer get?
Turn fault communication into traceable inspection and maintenance records
The goal of remote inspection is not to increase the burden on customers, but to allow the site, procurement, equipment managers and engineers to discuss issues based on the same set of data, reducing repeated questions, waits, and visits.
Remote inspection records
Organize operating hours, alarms, load rate, voltage frequency, oil pressure, water temperature and inspection photos to form a traceable record.
Abnormal judgment suggestions
indicates that the problem is more likely to come from the unit itself, ATS, low-voltage power distribution, load impact, maintenance gap or spare parts issues.
Maintenance and spare parts reminders
Remind maintenance windows, commonly used spare parts and high-risk components based on operating hours, site environment and failure frequency.
Onsite Service Preparation Checklist
When it is absolutely necessary to arrive on site, confirm personnel, tools, spare parts, shutdown windows, road conditions and on-site cooperation requirements in advance.
Engineer contact
Submit unit data, alarms and on-site photos, and make remote judgment first
It is recommended to provide unit model, controller photos, alarm codes, operating hours, current load, ATS or power distribution photos, recent maintenance records, failure videos and whether it affects drainage, crushing, ventilation, communications or camp power supply.
