The Jiangsu Du'an Environmental Protection NS-4 type submersible pump integrated monitoring controller is well-crafted, including a communication management chip. This chip is connected to the microcontroller and communicates with the computer terminal, transmitting transformer temperature information to the computer terminal. Preferably, a buzzer is also connected to the microcontroller, which is linked to the circuit of the temperature probe. When the temperature probe makes poor contact, the buzzer emits an alarm. Preferably, the display unit includes a digital tube, a digital tube driver circuit unit, and a key input control unit, as well as a key signal input editing unit. The digital tube is connected to the digital tube driver circuit unit and the key input control unit, the key signal input editing unit is connected to the digital tube driver circuit unit and the key input control unit, and the digital tube driver circuit unit and the key input control unit are connected to the microcontroller.
