    Introduction

    Mobile pumps are mainly used in low-lying areas, remote seaside locations and suburbs, for tasks such as flood control to provide relief from flash-floods, heavy rainfall, and even to mitigate or limit the occurrence of flooding. Through a wireless network with a backup mechanism, it is possible to remotely monitor the status of individual mobile pumps such as fuel level, power status, and unit temperature. GPS signal positioning provides pin-point accurate location details of each pump. This allows maintenance crews to quickly locate each pump and relocate them to where they are needed most to help control flooding. Additionally, water level monitoring equipment can provide warning in case of flash-flooding, allowing crews to retrieve the pumps before they are submerged and overwhelmed, preventing damage or loss of a unit.

    Solution

    The original mobile pump relied on maintenance personnel to physically confirm the fuel level, electricity and other conditions on location, making maintenance time-consuming and labor-intensive. During heavy rain falls, if the mobile pump relies on the presence of maintenance personnel to operate, this creates safety concerns for maintenance crews. Additionally, if the water level rises too quickly, there may not be enough time to rescue the pump before it is flooded. To solve these issues, of maintenance difficulties, personnel safety, and scheduling, we provided the following solutions:

    1. Add a gateway to the pump control board.

    2. Set up a management platform.

    Function Description

    1. The status of the pump is read by the controller and sent to the monitoring platform, including information such as oil pressure and temperature, battery charge, fuel level, pumping system information, and more.

    2. Remotely control the pump.

    3. Map mode to confirm the location of the pump unit.

    4. Maintenance records of the pumping unit can be kept on the platform.

    Hardware Architecture

    1. The pump control board is connected in series with the gateway via RS485.

    2. The gateway supports dual communication redundancy (supports NB-IoT/Cat-M1, 4G LTE, Wi-Sun, LoRa and other communication methods) (ODM/Project Base)

    3. Carrier dual backup (supports dual SIM cards)
