In the past, urban construction was "heavy on the ground, light on the underground", mainly relying on the expansion of above-ground space, the resources and environment were under excessive pressure, and the deterioration of the regional ecological environment was common. Due to the relatively lagging construction of the pipeline network, urban waterlogging and pipeline network accidents occurred frequently; For the municipal government, the network is like the blood vessels on the human body, with various pipes criss-crossing and running through every corner of the municipal government. For important places such as septic tanks, sewage treatment plants, landfills, chemical plants, underground pipe networks of mining enterprises, etc., the temperature, humidity, concentration of harmful gases, concentration of combustible gases and other environmental parameters in the pipe network must be monitored in real time. There are more and more data to be detected in the pipe network, and the centralized sensors originally set in the device can no longer meet the needs of the actual detection quantity. Failure to carry out early warning in time and deal with it correctly and effectively will lead to frequent accidents.

detailed description

As shown in Figure 1, an urban underground pipe network monitoring device includes: a power supply module, an acquisition module, a central control module, a communication module, and an expansion module. The acquisition module, central control module, communication module, and expansion module are respectively connected to the power supply module. The central control module sends acquisition commands to the acquisition module at fixed intervals, and the acquisition module transmits the collected data to the central control module. The central control module transmits the data It is stored and transmitted to the communication module, and the daily monitoring data is transmitted to the monitoring center server through 3G communication. Finally, the monitoring platform of the headquarters performs digital processing on the data, conducts quantitative analysis of the received data in sub-stations and segments, and completes the early warning and alarm functions. ; If an on-site alarm occurs, the monitoring data will be uploaded immediately, and an alarm message will be sent to the mobile phone of the relevant personnel; relevant measures such as early warning, alarm, and treatment will be taken through the established plan.

The antenna of the sensor and communication module is installed outside the lower bottom of the device's sealed housing, sealed by a special seal, the communication hole is cast with waterproof sealant, and the gas collection hole is sealed with a waterproof and breathable membrane.

The power module uses a 57Ah lead-acid battery to supply power for the acquisition module, central control module, communication module and expansion module. Realize low power consumption power supply.

The acquisition module includes a methane sensor, a hydrogen sulfide sensor, and a liquid level sensor. Each sensor works independently. Send the collected information to the central control module.

The central control module notifies the acquisition module and the expansion module to collect data according to the set cycle, and reports to the monitoring center. The collection time, storage time and reporting time interval can be set separately through the software; the data collected by the collection module can be stored locally, and the number of storage is not less than 170; the clock function, the clock reference is unified as the computer clock to ensure data simultaneity; automatically send early warning , Alarm text message function, such as gas concentration alarm is divided into two levels of early warning and alarm, when the water level exceeds the standard, the alarm will be uploaded immediately, when the environmental variable reaches the set alarm threshold of the device, the device will immediately send an alarm message to the relevant mobile phone, and the content of the message includes alarm equipment Number, location, alarm type and details, etc. Important data such as the current ambient temperature, humidity, network signal, battery power, and device operating status can also be uploaded. This module adopts the intermittent working mode, and collects data according to the set period.

The communication module supports WCDMA, TD-SCDMA, and CDMA-2000 communication technologies. It is equipped with a SIM card that enables GPRS data services and SIM short message services. It usually communicates wirelessly through GPRS, and uses short messages for areas with low carrier signal coverage. communication. Users can customize according to the actual situation, consider the degree of on-site signal coverage to choose an operator or set up wifi separately. The communication module wirelessly transmits the information stored in the central control module to the monitoring center server.

The expansion module reserves an interface for the sensor, including RS485 interface and RS232 interface, at least 2 interfaces, and the interface type and quantity can be set according to user needs. The access mode of the reserved interface of the sensor is current 0mA-20mA or 4mA-20mA, voltage-5V-5V, 0V-5V, 0V-10V.
