Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water meter production, and in particular to a detection device for producing NB-I0T Internet of Things water meters. Background Art
[0002] NB-IoT water meters are smart water meters that use narrowband Internet of Things (NB-IoT) technology for remote communication. They enable automatic remote meter reading, reduce labor costs, and support multiple payment methods, such as post-payment, pre-payment, and mixed charges. In addition, NB-IoT water meters usually have valve control functions, allowing management departments to remotely control water flow and realize automated water management.
[0003] After the NB-I0T Internet of Things water meter is produced, it needs to be tested. The conventional detection method is to use a fan to blow air into the inside of the NB-I0T Internet of Things water meter. The NB-I0T Internet of Things water meter has a water inlet interface and a water outlet interface. First, blow air into one of the interfaces, and then observe the changes of the NB-I0T Internet of Things water meter. Reverse the NB-I0T Internet of Things water meter, blow air into the other interface again, and then observe the changes of the NB-I0T Internet of Things water meter, and then compare the two data. If they are the same, they are qualified. This "wind instead of water" method is used to simulate the process of water flowing through the inside of the NB-I0T Internet of Things water meter, so as to detect the performance of the NB-I0T Internet of Things water meter.
[0004] This "wind instead of water" detection method can increase the detection efficiency of NB-I0T IoT water meters. However, the detection steps are still too cumbersome. The NB-I0T IoT water meter needs to be reversed during the detection process, and only one NB-I0T IoT water meter can be detected at a time. The detection efficiency needs to be further improved.
