An nb-iot IoT smart water meter

Abstract

The invention relates to an NB-IoT internet of things intelligent water meter. The NB-IoT internet of things intelligent water meter comprises a main body, a display screen, two fixed pipes and two connection pipes, wherein the display screen is arranged on the main body, the two fixed pipes are respectively arranged at two sides of the main body, one end of each fixed pipe is connected with the main body, the connection pipes are in one-to-one correspondence and are coaxially arranged, inner diameters of the connection pipes are equal to external diameters of the fixed pipes, external threadsare arranged on the fixed pipes, internal threads are arranged on inner walls of the connection pipes, a signal transceiving module is arranged on the main body, auxiliary mechanisms are arranged onboth of the connection pipes, and a locking mechanism is arranged in one of the connection pipes. By the NB-IoT internet of things intelligent water meter, stress at connection positions of the connection pipes and the fixed pipes is reduced by the auxiliary mechanisms, and the situation that the threads are deformed to affect sealing performance between the connection pies and the fixed pipes isprevented; and moreover, the situation that water is sprayed by under-pressure operation to make a surrounding object damped is prevented by the locking mechanism.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to an NB-IoT Internet of Things smart water meter. Background technique [0002] Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180kHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. NB-IoT is an emerging technology in the IoT field, which supports cellular data connections of low-power devices in wide area networks, also known as low-power wide area networks (LPWAN). NB-IoT supports efficient connection of devices with long standby time and high network connection requirements. It is said that NB-IoT device battery life can be improved by at least 10 years, while also providing very comprehensive indoor cellular data connection coverage. [0003] A smart water meter i...

Problems solved by technology

[0003] A smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption, transfer water data, and settle transactions. The existing smart water meters are equipped with water inlet pipes and outlets. The water pipe, and the water inlet pipe and the water outlet pipe are connected with the external water pipe through thread connection. When the water flows in the smart water meter, the resistance of the parts in the smart water meter to the water flow will make the water inlet pipe and the water outlet pipe connect with the external water pipe. The threaded connection of the water pipe is stressed, which will affect the increase of the gap at the threaded connection for a long time, affecting its sealing performance, and it is easy to deform the thread. Not only that, when the smart water needs to be replaced due to damage, if the replacement personnel due to Comfortable but forget to turn off the water supply equipment, it is easy to make the water overflow, causing the objects around the smart water meter to be damp, and in severe cases, it will also cause electric leakage
