Content Description
The invention relates to the technical field of water meters, in particular to an intelligent water meter for internet of things.
Background of the invention
A water meter is a meter that measures the flow of water. Most of the cumulative flow measurement of water. It is generally divided into two types: volumetric water meter and speed water meter. The accuracy of the former is higher than that of the latter, but it requires high water quality, and the water is easily clogged when containing impurities. The meter recording the water consumption of tap water is installed on the water pipe. When the user discharges the water, the indicator or character wheel on the watch turns to indicate the amount of water passing through.
The water meter was invented by British Klus in 1825. China's water meter use and production started relatively late. Since the invention of a balanced tank water meter with instrument characteristics in 1825, British Kluth has developed nearly two of the water meters. A hundred years of history. Water meter use and production started late in China. In 1879, Li Hongzhang established the first water plant in China at the port of Lushun. In 1883 the British colonialists established a second water plant in Shanghai and the water meter began to enter China. With the construction of water plants in some coastal cities successively, by the 20th century, Shanghai Guanghua Machinery Factory (now the predecessor of Shanghai Guanghua Instrument Factory) and other parts imported water meters from abroad. For quite a long time, the water meters of countries such as Britain, France, Japan and Germany have occupied the Chinese water meter industry. These meters with different varieties and specifications have brought different standards due to different standards and parts cannot be exchanged. Great difficulty.
After the liberation in 1949, with the development of urban water supply, China's water meter industry also developed accordingly. Since 1955, water companies in Shanghai, Beijing, Tianjin, Nanjing, Wuhan, and Guangzhou have begun producing water meters. In the early 1980s, the water meter industry was organized by the Shanghai Industrial Automation Instrumentation Research Institute of the Ministry of Machinery Industry. According to the requirements of the international standard ISO4046 for water meters at that time, a water meter with eight pointers and integral impellers was designed for the nationally unified design of small-diameter water meters. . The unified design and the plasticization of water meter components have created favorable conditions for the organization of specialized production of water meters, greatly promoted the progress and development of China's water meter industry, and met the growing demand of urban and rural tap water industry development.
In the 1990s, China's economic construction continued to develop at a rapid rate, and the water meter industry also developed rapidly. Both the number of enterprises and the total output have more than doubled, and various intelligent water meters and water meter reading systems have begun to emerge. Accurate measurement can save resources. Patent document CN201510632493 .5 discloses an IoT smart water meter with a ladder pricing function, which belongs to a water meter and includes a ladder pricing main control module, a wireless communication module, a clock chip, and a water flow measuring device. The main control module of ladder pricing is respectively connected with a wireless communication module, a clock chip, and a water flow measuring device. The main control module of ladder pricing includes a processor and a memory, and the processor and the memory are connected; the wireless communication module is also connected to the Internet of Things. The price plan instruction transmitted by the control end is transmitted to the processor; the terminal simultaneously synchronizes with the control end in the process of communicating with the control end, so that the time of the table end is always consistent with that of the control end, so as to avoid the time deviation between the two. Lead to pricing and price adjustment is not uniform; can also be based on the end of the cycle in the price plan to determine whether to end the current cycle, in addition to time synchronization, the entire process is completed at the table side.
The above-mentioned patent documents can realize the ladder pricing function and accurately measure the user's water consumption, but there is no technical solution for how to provide an easy-to-use, simple-structured Internet of things smart meter.

Actually, a wiper assembly that refuses to move might have a simple blown fuse. But usually fuses don't blow on their own. Even at full stall, the current draw of the motor should be well below the fuse's rating. If the fuse is blown, odds are there's something else wrong, like a shorted wiper-motor armature or faulty wiring anywhere along the harness between the motor and the switch. Even a mechanical problem like a seized bushing can make a fuse eventually fail.
The fuse is okay, or you've replaced it with one that has the appropriate amp rating. There's still no action? With the wipers and ignition on, whack the motor assembly with the handle of a screwdriver or a rubber mallet. If that gets things moving, you've got a bad commutator or an open winding on the armature. When the motor parks, if the brushes are sitting on the bad segment, no current flows. Whacking the whole business smartly can sometimes jolt things into motion. Because there are often a dozen windings on the armature, the motor runs fine until the next time it comes to rest on the bad spot.
