Using gyro sensor, low power consumption technology, wireless transmission NB-IOT or CANT.1 networking technology, with monitoring displacement, vibration, ambient temperature, gas monitoring, water quality PH value or turbidity (optional), dynamic fluid Bit height, flow, online monitoring of the vibration or posture of the measured object has been moved, upload to the cloud platform, through the monitoring platform software and mobile APP, display the location alarm address and type. Built-in battery standby time of 3-5 years, protection grade IP68
1. Manhole cover status monitoring
Control the inclination of the manhole cover, the opening of the manhole cover, and the monitoring of displacement status. A manhole cover detector is installed on the manhole cover, and the terminal monitors the state and trajectory analysis of the manhole cover through the full-axis inclination angle sensing technology. Know the abnormal information of manhole cover at the first time, schedule and deal with it in time, and greatly improve the management efficiency. Realize real-time alarm when abnormality is found, prevent in advance, actively manage, reduce maintenance costs and losses, and discover and eliminate potential safety hazards in advance.
2. Intelligent monitoring of underground water level
Through the installation of intelligent monitoring terminal for underground water level, the collection method of dynamic overload of underground water level is strengthened, and overflow alarm is realized.
3. Water quality monitoring
Collect water quality PH value, TDS, etc., and upload to the cloud server platform to assist in the detection of mixed flow of rain and sewage.
5. Toxic and harmful gas monitoring H2S, CH4 and other toxic and harmful gas monitoring in wells.
6. Support NB-IoT communication mode, support MQTT/CoAP and other protocols
7. The battery voltage is collected for communication and low voltage alarm is realized.
8. In case of emergencies, the system will automatically send out alarm information and signals to notify relevant personnel to take emergency measures to avoid accidents;
9. Ultra-low power consumption design: The product adopts micro power consumption design, built-in battery power supply, under ideal environment, the battery life can be as long as 3-5 years.
10. Timing status reporting function: The NB-IoT smart manhole cover monitoring sensor adopts a micro-power consumption design and is in sleep mode when there is no cover opening alarm event. The device can regularly report device status information every day, including battery voltage and manhole cover status. And other information, even if there is no alarm event, you can grasp the equipment running status every day.
11. Alarm event filtering: The device has a multi-level alarm event filtering function to avoid false alarm events caused by vehicle passing and vibration. By avoiding the transmission of false positive information, the energy consumption can be effectively reduced.
12. Remote parameter configuration: After the installation of the NB-IoT intelligent manhole cover monitoring sensor is completed, the device can be configured with remote parameters as required, which is easier to use and more convenient to maintain.
13. Intelligent design: The product adopts intelligent function design, integrates edge computing, effectively filters false alarm information, and ensures the normal operation of equipment. It has configurable transmission period and acquisition period, and reports alarm information immediately when the state of the manhole cover changes, so as to report any changes.
14. Easy installation and easy maintenance: the product can choose screw fixation, glue fixation, bracket fixation and other installation and fixation methods, which are suitable for the installation and monitoring of manhole covers of different shapes and types. A screwdriver can complete the removal and installation of the device.
It is suitable for monitoring manhole covers of municipal, electric power, water, operators, heat, etc.
