1. Operation and Maintenance Efficiency: From "passive emergency repair" to "proactive prediction", significantly reducing downtime

The operation and maintenance of traditional cold storage units rely on regular manual inspections. Problems are often not discovered until the equipment malfunctions and stops, and maintenance personnel need to conduct on-site investigations, which is extremely inefficient. The remote 4G module has completely transformed this model through real-time data transmission and remote control:

Real-time status monitoring and second-level fault early warning

The module can collect key data of the unit in real time (such as the operating status of the compressor, evaporation/condensation temperature, temperature and humidity inside the warehouse, current and voltage, refrigerant pressure, etc.), and upload it to the cloud platform via 4G network. Once the data exceeds the normal threshold (such as abnormal increase in warehouse temperature or compressor overload), the system will immediately alert the operation and maintenance personnel via text messages, APP push notifications, emails, etc., to prevent the "expansion of faults" (for example, goods deterioration due to excessive warehouse temperature).

Remote troubleshooting and precise maintenance reduce on-site travel

Operation and maintenance personnel can view the operation logs of the units and fault codes (such as "Compressor high-pressure protection" and "fan failure") through the cloud platform without having to go to the site. They can initially determine the cause of the fault and prepare the corresponding parts in advance, avoiding the ineffective cost of "multiple on-site trips for investigation". For instance, if the warning indicates "warehouse temperature sensor failure", maintenance personnel can directly bring a new sensor to the site for replacement, solving the problem at once.

Remote emergency control reduces sudden losses

In case of unexpected situations (such as when maintenance personnel are temporarily unable to arrive but there is a slight risk of the warehouse temperature exceeding the standard), the parameters of the unit can be remotely adjusted through the cloud platform (such as increasing the compressor frequency or starting the backup fan), or the "emergency cooling mode" can be activated to temporarily stabilize the environment inside the warehouse and buy time for on-site maintenance.
