Embodiment 1

[0036] refer to figure 1 As shown, the present embodiment introduces an auxiliary monitoring system for a pipe gallery tunnel, including a control unit; the pipe gallery tunnel includes SF6 exhaust passages, inspection passages and main passages extending along the length direction of the pipe gallery tunnel respectively; There are ventilation valves; the two ends of the inspection channel and the main channel are respectively equipped with a blower and exhaust fan, and the two ends of the SF6 exhaust channel are respectively equipped with an SF6 exhaust fan; there are multiple SF6 in the inspection channel and the main channel along the extending direction of the channel sensor, temperature and humidity sensor, harmful gas sensor and oxygen sensor; the output terminals of the SF6 sensor, temperature and humidity sensor, harmful gas sensor and oxygen sensor, and the control terminals of each ventilation valve, blower and exhaust fan are respectively connected to the control uni...

Embodiment 2

[0043] Based on the auxiliary monitoring system of embodiment 1, the monitoring method of the present embodiment includes:

[0044] Obtain the detection data of SF6 sensor and temperature and humidity sensor in real time, as well as the switch status data of each fan and ventilation valve;

[0045] According to the obtained detection data, the working conditions in the tunnel of the pipe corridor are judged, and the working conditions include the SF6 early warning working conditions, SF6 alarm working conditions and other gas accident working conditions which are preset according to the SF6 concentration and correspond to different concentrations, and according to the Temperature and humidity pre-set working conditions to be exhausted;

[0046] According to the judgment results of the working conditions, according to the preset fan and valve control strategy, control the switches of different fans or valves at different positions in the pipe gallery tunnel, so that the tempera...

Embodiment 2-1

[0056] Based on Embodiment 2, this embodiment specifically introduces a monitoring method for an auxiliary monitoring system for a tunnel tunnel, including the following:

[0057] Step 1. Collect the status data of key equipment such as fans and ventilation valves: including the opening and closing status of vertical, horizontal, SF6 fans and pipe corridors; at the same time, the fans and ventilation valves can be opened through communication or hardware nodes The remote control of closing and closing can remotely adjust the air volume of the fan through the communication mode with the frequency converter;

[0058] Step 2, collect data of various types of sensors such as gas, temperature and humidity installed inside the pipe gallery: including gas sensor data such as SF6, CH4, CO, H2S and oxygen inside the pipe gallery, temperature and humidity sensors, wind speed and wind pressure sensors, etc.;

[0059] Step 3: Classify and display the collected data in a centralized manner...

Abstract

The invention discloses an unattended operation mode pipe gallery tunnel auxiliary monitoring system and method. The system comprises a control unit. A pipe gallery tunnel comprises an SF6 exhaust channel, a patrol channel and a main channel. A ventilation valve is arranged between every two adjacent channels. Air supply machines and exhaust fans are correspondingly arranged at the two ends of thepatrol channel and at the two ends of the main channel. SF6 exhaust fans are correspondingly arranged at the two ends of the SF6 exhaust channel. A plurality of SF6 sensors, temperature and humiditysensors, harmful gas sensors and oxygen sensors are arranged in the patrol channel and the main channel in the extending direction of the channels. The output ends of the SF6 sensors, the temperatureand humidity sensors, the harmful gas sensors and the oxygen sensors and the control ends of the ventilation valves, the air supply machines and the exhaust fans are connected with the control unit. By using the unattended operation mode pipe gallery tunnel auxiliary monitoring system and method, the environment in a pipe gallery can be monitored, the fan and ventilation valve control can be carried out on the environment parameters in the pipe gallery according to the actual working condition or the required working condition, the manpower input of pipe gallery monitoring is reduced, and thediscovery and response efficiency during sudden accidents in the pipe gallery is improved.

Description

technical field [0001] The invention relates to the technical field of pipe gallery monitoring, in particular to an auxiliary monitoring system and method for pipe gallery tunnels in an unattended mode. Background technique [0002] In recent years, with the rapid development of urbanization, the pipeline tunnel project has sprung up in large numbers. The traditional pipeline tunnel auxiliary monitoring system has a high degree of dependence on operation and maintenance personnel and a large inspection workload. shortcoming. Contents of the invention [0003] The purpose of the present invention is to provide an auxiliary monitoring system and method for an unattended mode pipe gallery tunnel, which can monitor the environment inside the pipe gallery, and can control the environmental parameters in the pipe gallery according to the actual working conditions or required working conditions. Reduce the manpower input in the monitoring of the pipe gallery, and improve the eff...
