Core Function
- In the cell phone + back clip working mode, we can directly connect the back clip via Bluetooth on site, scan the new/old meter code, and utilize the power infrared to realize one-click reading of the meter code, and complete the one-click meter change operation.
- Reducing process flow, realizing one-click meter/box replacement, compressing the 7 steps of the original ticket into 3 steps, and reducing the time for meter replacement from 2 hours to 30 minutes.
- The cell phone application obtains the authority to set the parameters of the power meter and the clock setting ticket from the collection main station, connects to the back clip via Bluetooth, and sends the timing or calibration commands to the power meter by using the power infrared of the back clip to complete the on-site calibration work.
- The cell phone application obtains the authority to set the parameters of the power meter and the on site power-off/on task ticket, connect back clip via Bluetooth, using the back clip power infrared to send meter connect or disconnect command.
- Combined with the electronic sealing of metering devices, it provides technical means for on-site inspection of electricity theft behaviors such as private tampering and short connection.
Product Advantages
- Including Bluetooth communication, RS485 communication, infrared communication, security unit, barcode scanning, high-frequency RFID function and soft encryption communication.
- In the field operation and maintenance work, the product can perform on-site supplementary reading, on-site power outage and resumption, parameter setting, on-site calibration, key installation, tariff adjustment and on-site recharging of the meter, and it can also be used to configure the parameters through infrared communication with the terminal equipment.
- In addition, the product also has portable charger, mobile hotspot and mobile hard disk functions. The portable charger function can be used to charge the cell phone used on site to improve efficiency.
- The mobile hotspot function can be used for on-site WIFI connection of cell phones. The mobile hard disk function can be used as the storage disk of the cell phone to expand the cell phone storage files.
- This product is a comprehensive field service product, external terminals (cell phones, tablets) connected to the product through the Bluetooth interface, human-computer interaction operations in the terminal applications.
Application Scenario
In order to enhance the rate of staff mobile handheld facilities and equipment provision, maximize the satisfaction of business needs, and improve the efficiency of on-site operations, we upgraded the staff mobile work terminals and promoted the "cell phone + back clip" work mode. At the same time, in order to focus on resource sharing and reject blind configuration and idle waste, the company carries out the pilot project of "cell phone + back clip" working mode and promotes its application in accordance with the construction principle of "unified planning and step-by-step implementation".
