[ Chinese instrument network instrument research and development ] With the development of technology, various instruments and meters are constantly improving. At the same time, in the daily work and life, the use of instrumentation is also more and more frequent, it can make monitoring and measurement. Become more convenient.
　　 From traditional ranging wheels to digital rangefinders
At the scene of previous accidents, on-duty personnel used the conventional distance measuring wheel to measure the data points of a car accident in a walking manner, which was not only inefficient but also dangerous.
The digital distance meter can not only solve the problem well, but only need a simple button, and it can effectively improve the time efficiency of on-site search and ensure the safety of on-site staff. At present, the Taichung City Police Department’s Traffic Brigade has purchased 68 digital rangefinders, which is conducive to the conduct of traffic accidents by on-duty police officers at night, fast speed, and heavy traffic.
In addition to the digital range finder, the Taichung City Police Traffic Brigade innovated the “real-time video back camera†and collaborated with a space patrol aircraft to monitor it, forming a land-to-air pincer to monitor the traffic conditions in Taichung City and returning the image to the service center through traffic conditions. The TV wall banned traffic violations.
Smart flood prevention system real-time monitoring
At present, Fujian Putian City Water Conservancy Bureau has set up four smart flood prevention systems to monitor Putian “suffocation†in real time.
The smart flood prevention system can collect real-time information such as working conditions, water conditions, customs, etc. by building a remote video surveillance system for water projects; by setting up a weather monitoring system, it can provide effective meteorological information for the flood prevention command; by building a flood warning and dispatch system, Accurate monitoring of site rain, clear water, timely warning, and forecasting of flood conditions to conduct scientific scheduling; through the establishment of a flood prevention video conferencing system, it is possible to realize remote business consultation and remote command.
Multiple sensor combinations sense bridge dynamics
While the process of urbanization is accelerating, the construction of urban transportation infrastructure has also entered a peak period, but management has lagged behind construction and has become common in all cities.
When each car passes over the bridge, each pier will have a slight tilt. Although it cannot be seen by the naked eye, it will not escape the eyes of the pier tilt monitor. This data will be transmitted to the monitoring platform through the wireless network if the tilt value Break through the normal range, the system will immediately report to the police. At the same time, geomagnetism traffic sensors not only can monitor the traffic volume, but also can sense the vehicle through the change of magnetic field, analyze the size and weight of the vehicle through the vibration frequency, and then send the data to the municipal law enforcement bureau through the data transmitter. The information system analyzes the size of traffic, whether it needs to be diverted, and whether the bridge is overloaded.
In addition, there are bridge fastness tester, expansion joint monitor and bridge strain monitor. Through the application of these sensors, better management of bridge safety.
Followed by inspection of emergency mobile water quality monitoring experiment platform put into use
Recently, the emergency mobile water quality monitoring experiment platform implemented by Shanghai Municipal General Administration of Administration was put into use, and was specifically used for water quality monitoring under emergency conditions. This move will make Shanghai's water quality early warning and emergency response system more perfect, and it can escort Shanghai's water supply security.
Around the needs of water quality monitoring, the platform is equipped with comprehensive auxiliary systems including water supply systems, ventilation systems, air conditioning systems, lighting systems, power supply systems, mobile video surveillance systems, and data acquisition and transmission systems. In addition to using the emergency mobile water quality monitoring experiment platform to conduct surveys, plots, sampling, and tracking in polluted waters, in addition to routine water quality indicators such as turbidity and chromaticity, the experimental platform can also monitor common volatile, semi-volatile organics, nitrogen, phosphorus, and heavy metals. Other monitoring capabilities.
