Product Description
Standard protocol Lorawan module for smart water meter
LoRaWAN Technology IntroductionLoRaWAN has the characteristics of multi-channel access, frequency switching, adaptive rate, channel management, regular sending and receiving, node access authentication and data encryption, roaming, etc.The entire solution include data perception terminal (meters) , data transmission terminal (gateway), and data management terminal (software platform, server, PC or Mobil phone) as following construction:Thus it has following advantages:1. Good Compatibility. The protocol on LoRaWAN and the interface of the data cloud platform are unified,different sensor nodes of different manufacturers can access the same LoRaWAN network.It is not necessary for application developers to customize all sensors, which can shorten the development cycle and reduce the development cost.2. Large Network Capacity. The LoRaWAN network has bigger data capacity and more access nodes, and strong scalability.It is beneficial for application developers to develop larger-scale applications and upgrade applications continuously.3. Excellent Security. The LoRaWAN network has designed security mechanisms such as node access authentication and data encryption. These mechanisms have been reviewed by industry experts and verified by a variety of applications from various technology companies around the world. Compared with the temporary agreements of application developers, its security grade will be much more higher.It can guarantee the continued security of the application.4. Sustainable Expansibility.With the evolution of the LoRaWAN network standard, it can continuously add features such as positioning, roaming, broadcasting, and multicast.That's to say,it can benefit from a common technical platform continuously.Functions- Sampling Measurement
It can realize a variety of sampling methods, such as reed switch, Hall and other pulse sampling methods, and also photoelectric sampling methods; - Control Valve
The upstream computer can perform valve control operation on the meter through preset commands; - Close Valve When Attacked
When the meter is under magnetic attack, it can upload the data frame and close the valve.After the attack disappears,it can upload the data frame and open the valve;3.In Place DetectionWith switch in place detection function, when the normally open contact is closed in place,the valve operation can be stopped immediately;4.Upload RegularlyThe module automatically uploads a frame of meter data every 6 hours;5.Trigger UploadThe module is usually in the standby state, and the module can upload the real-time data for one time by triggering switch;6.Valve Failure DetectionAutomatically determine whether the valve limit switch is working properly. When the limit switch fails, the backstage will be reminded of alarming.7.Reed Switch Failure Detection (For reed sampling water meter)When the sampling reed switch or Hall element fails, the meter will upload a malfunction indication of the reed switch, and the meter will no longer measure until it covers to normal state;8.Infrared CommunicationVarious parameters such as meter address, table data and LoRaWAN key can be set by infrared communication.Parameters:| Parameter | Value | P.S. |
