The invention discloses a valve pit monitoring system. The valve pit monitoring system comprises a server and an RTU system. The RTU system comprises a power source, an integrated circuit board and apressure sensor. The integrated circuit board is provided with a CPU, a power interface, a signal interface, a communication module, a plurality of AI modules and a plurality of AO modules. The powersource is connected with the power interface through a power line. The communication module is connected with the server. The pressure sensor is connected with the signal interface through a signal line. The AI modules and the AO modules are connected with other sensors or actuators in a valve pit. The power interface, the signal interface, the communication module, the AI modules and the AO modules are all electrically connected with the CPU. The invention further discloses a monitoring method. The method comprises the steps that a gas pressure signal in a pipeline is detected through the pressure sensor and transmitt
