Click on the quantity：468June 17, according to the Central Weather Bureau website, the Central Weather Bureau June 17, 06:00 continued to issue orange rainstorm warning: it is expected, June 17, 08:00 to 18:08, south-central Jiangnan, southern Guizhou, northeastern Yunnan, northern China and other parts of the region have heavy to heavy rain, of which the southern part of Hunan, Jiangxi, central, southern Zhejiang, northern Fujian, northeastern Guangxi and other places in parts of the region There are heavy rain, northeastern Guangxi and other places in the localities of very heavy rain (250 ~ 270 mm). Some of the above areas are accompanied by short-term heavy precipitation (maximum hourly rainfall of 30 to 50 millimeters, localities can exceed 70 millimeters), local thunderstorms and gusty winds and other strong convective weather.

Recently, there has been extensive rainfall in several cities across the country, with many provinces and cities experiencing heavy rainfall or even exceptionally heavy rainfall. Heavy rainfall not only has a significant impact on rivers, lakes and mountain villages, but also has a great impact on normal working life in the city, especially tunnels, culverts, under overpasses, low-lying roads, squares and other low-lying places are very prone to waterlogging, resulting in urban flooding, which brings about flooding of roads, damage to buildings, disruption of transportation and telecommunications, etc., and has a great impact on transportation, industrial production, commercial activities, daily life of the citizens, etc. This has a great impact on transportation, industrial production, commercial activities and daily life of the citizens.

At present, in the rainfall waterlogged road, mainly by mechanical scale to remind pedestrians and vehicles in this section of the depth of water, but the mechanical scale needs to be vehicles to the front to see the depth of water, when the vehicle has been involved in the water, the damage has been caused. Using this method, the timeliness is relatively poor, we need to be more intelligent and convenient, more timely water early warning methods.

Xi'an Chinastar M&C Ltd. self-developed city flooding system uses sensors to monitor the waterlogging status of bridges, tunnels, culverts and other low-lying places in real time, and employs edge computing, wireless transmission, cloud computing and other technologies to obtain the monitoring results. Real-time fault information will be pushed to the maintenance personnel and start the scene of automatic blocking system to realize automatic blocking (forward blocking, reverse release, to protect the trapped vehicle out), in addition, set up in the vehicle to enter the LED display and sound and light alarm to remind the vehicle is prohibited to drive into. Cameras can observe the site conditions, and manual intervention facilitates staff dredging and on-site processing. In order to improve the intelligence and advancement, the micro-weather monitoring system can monitor the on-site environmental conditions and show in the LED display; the well cover movement + water level exceeding the limit monitoring system can real-time monitor the status of the well cover and whether the water level under the well exceeds the set limit.
Urban flooding system plays a very important role in the process of urban flood control, the system from the pre-flood micro-meteorological monitoring, perception forecast to the flood of real-time monitoring, sound and light alarms, voice broadcasting, automatic blocking, intelligent reporting, sending orders for rescue, and then to the post-flood statistical analysis of the data to a full range of all-round, full-cycle monitoring data as the basis for scientific decision-making, in order to achieve the purpose of early warning and disaster reduction.
PERCEPTION DEVICE
Micro meteorology monitor system: monitor the site environment (temperature,humidity,wind speed,PM2.5,etc.).
Manhole cover+water level monitoring：monitoring of manhole cover status is triggered when the cover is tilted due to opening, moving, breaking and falling.，whether the water level in the well exceeds the limit.
Audible & visual alarm: When the rainfall ≥ preset value (e.g. 0.5m), the sound and light alarm emits flash warning and voice broadcast reminder.
Video monitoring：It is convenient for the monitoring center to check the scene at any time and remotely arrange personnel to the scene to investigate the police situation and evacuate vehicles.
Wireless level monitoring: Real-time monitoring of the state of waterlogging, waterlogging alarm remote reminder, dual power supply to avoid power outages resulting in malfunctioning, equipment anti-sediment.
Barrier gate：Under normal condition, the road gate is raised and the vehicle can be driven normally; when the rainfall ≥ preset value, the road gate blocks the forward vehicle, and the vehicle that has been entered is allowed to pass in the reverse direction (blocking in the forward direction and releasing in the reverse direction, which can be manually intervened).
LED display screen：When it is not raining, it displays temperature, humidity, wind direction, wind speed, atmospheric pressure, rainfall, PM2.5, etc. (specific content is optional), when rainfall ≥ preset value, the display switches to show the waterlogging information.
APPLICATION PLATFORM
The large screen displays the number of devices, site distribution, alarm information statistics, recent alarm information, and recent report statistics.
The platform mainly contains modules for equipment management, equipment monitoring, maintenance personnel, system management, system maintenance and so on.
Alarm Push
When the device reaches the alarm threshold, the system will issue an alarm on the application platform and send an SMS to the cell phone number of the maintenance personnel bound to the device;
Real-time View
Through the application platform, you can view the status information of the relevant equipment, the relevant location and the corresponding maintenance personnel in real time;
Hierarchical Management
According to the management implementation system can be set hierarchically backstage main administrator, ordinary administrator, maintenance personnel, and support for self-added maintenance roles, according to different management and maintenance roles can be set up for different management privileges;
Data Statistics
The platform automatically records and counts historical alarm information and maintenance information to provide data support for urban flood control management analysis;
FUNCTIONAL CHARACTERISTICS
APPLICATION SCENARIO
Underpasses, tunnels, culverts
Monitor the internal waterlogging status and surrounding environmental information (micro-weather) of water-prone sections such as underpasses, tunnels, culverts, etc. in the city. Real-time monitoring of liquid level height and setting alarm level according to the standard, displaying the height of waterlogging at the setting information reminder to remind pedestrians and vehicles to prohibit traffic, in addition, real-time display of the surrounding meteorological information when waterlogging does not occur.
Older neighborhoods and communities
Some of the old neighborhoods and communities have imperfect drainage systems and are prone to internal waterlogging. Use the waterlogging monitoring terminal to monitor the height of waterlogging and report the location of waterlogging to the management center in real time. According to the reported information, the person in charge can go to the scene in time to deal with it
