The invention relates to a negative pressure measurement and control system in a sewage pipeline. The negative pressure measurement and control system comprises a power supply unit, a main control unit, a 4G communication module, an LORA communication module, a 485 communication module, a lamplight display module, a gas pressure sensor, a liquid level instrument, an electromagnetic valve, a power supply controller, a server and an upper computer. The system has the beneficial effects that equipment used for monitoring and treating liquid level and pressure abnormity in the sewage pipeline is managed through the Internet of Things and an informatization mode; and the state and data of each device are monitored in real time, and an alarm is automatically given when the device data is abnormal. The alarm information is generated according to last real-time data of the equipment and configuration parameters of the equipment, and when the uploaded data exceed a threshold value, alarm information is automatically g
