Helping work and life talk about fun and practical instruments

[ Chinese instrument network instrument research and development ] Instrument, refers to the science and technology for the experiment, measurement, observation, inspection, drawing and other apparatus or device. In addition to industrial production and scientific research, many instruments have appeared in many aspects of our lives, ensuring the smooth progress of our daily lives, and at the same time making some tasks easier and more efficient.

　　 Garbage dirty and heavy truck weighing system 1 second measurement

Call it a name and sweep it, and the garbage data is fully known. That's right, this is the newly-launched on-board weighing system in Jianggan District of Hangzhou, Zhejiang Province. The main components of this system are the load sensors and garbage meters carried by each vehicle.

After the weighing sensors used in the system have undergone continuous R&D and reforms in the background technology, the amount of waste can be accurately measured even in the reversed state. The entire weighing process takes only one second and no additional operations are required for the removal personnel. At the same time, researchers implement a vehicle-by-car ID and real-time measurement accuracy. At the pick-up truck site, each vehicle is equipped with a garbage quantity recorder. The recorder will record data in real time according to the rubbish removal trajectory and the on-board weighing system, so that it can be used to analyze the trend of its solid waste at a later stage using big data analysis. Predict.

It is understood that the system has now been piloted at the Taiping Mun Zhijie, Jingfang District 2 transit station, and Zahe 2nd district, leading the garbage removal into the “2.0 version”.

Water flow rate measurement is difficult to realize real-time observation using handheld electric wave current meter

On May 1st, Yangzhou, Jiangsu Province will enter the reclamation area. The Yangzhou Branch of the Provincial Hydrology Bureau will fully carry out the urban flood control and hydrological emergency monitoring exercise. The “ Fighting artifact” hand-held electric wave current meter will make its debut.

Hand-held wave current meter is like a pistol, as long as the "muzzle" against the river under the bridge, the water speed is immediately displayed on the screen. The instrument uses the principle of radar speed measurement, designed specifically for measuring the surface velocity of the water body. By collecting hydrological data, real-time observations of surface water, precipitation, drought, and water quality in river basins, and then performing calculations and data compilations on measured hydrological data can provide an important role in downstream flood discharge.

Water depth too smart cover sensor indicates impossible

In the past, there were frequent news that pedestrians accidentally fell into wells or the depth of water in the city caused pedestrians to bypass the road. Today, with the construction of smart well covers, the probability of accidents will be greatly reduced. At present, Fuzhou City, Fujian Province has installed 350 sets of smart manhole covers in the city to achieve full coverage of dynamic monitoring of 47 main points and key areas in the four urban areas.

The smart manhole cover is composed of multi-layer devices, and the device attached to the manhole cover is an alarm. There are two square boxes inside the well. They are smart monitoring devices for well covers. One of them is used to monitor the water level in the well and the other is used to monitor the water level in the well. Once the well water level or the height of the well water exceeds the warning value, the well cover will notify the command platform for the first time so that the workers can quickly locate and drain the water. At the same time, the intelligent well cover is equipped with a smart lock, and the technician can open it through the electronic key. Forced opening or shifting will trigger an alarm. Smart monitoring equipment is also installed in the well cover. The platform can monitor the opening and closing status of the well cover in real time, so the well cover is moved once. At a time, researchers will come to handle it.

Through the development and application of these instruments, we can make our lives more secure and reduce the occurrence of some accidents. At the same time, we also greatly reduce the labor costs and increase the efficiency of our work.
