1、 Background

The total electricity bill in the workshop remains high, but it is impossible to find which equipment is secretly consuming electricity. Manual meter reading is time-consuming and labor-intensive, and data statistics often lag behind production by more than three days; Without any warning before the equipment trips due to overload, stopping the machine can result in tens of thousands of yuan in losses, which is the frustration of countless production managers. Nowadays, the emergence of WiFi smart meters is solving the problem of industrial energy management with the combination of "accurate measurement+fast transmission".

2、 Case Study

Electricity monitoring scheme for a certain automotive parts factory in Suzhou

Requirement 1: It is necessary to monitor the electricity consumption of the equipment and collect data;

Requirement 2: Production equipment is widely distributed and scattered, and wiring is inconvenient, requiring wireless communication function

Requirement 3: Data needs to be transmitted via internal network to ensure data security.

The solution we provide for the above issues is an intelligent WiFi meter, which is easy to install and can wirelessly transmit data within the network.

Advantages of WiFi meters:

1. Distributed installation, convenient networking.

1. Supports 2.4GHz WiFi frequency band, requiring low bandwidth for WiFi meter data interaction, which is very practical. And this WiFi frequency band has wide coverage and strong penetration.

3. Convenient access to data. The electricity meter supports Modbus TCP protocol and real-time synchronization platform, greatly saving labor costs.

4. Convenient network management and control. Electric meters can be manually or automatically assigned IP addresses, which can quickly locate problems and facilitate control for devices that are offline or have abnormal data collection.

3、 ADW300 IoT Product Introduction

1) Product Overview

The ADW300 wireless measuring instrument is mainly used to measure the three-phase electrical parameters of distribution circuits. It has the advantages of small size, high accuracy, and rich functions. It supports RS485 communication and wireless communication methods such as Lora, 4G, wifi, etc. It also adds a current sampling mode for external transformers, making it convenient for users to quickly install and use it in different situations.

2) Product usage

The electricity meter is installed in a 35mm rail type, and ADW300, ADW300-HJ, and ADW300W can all use three-phase four wire or three-phase three wire wiring methods.

It can be installed without electricity on site. Voltage sampling: optional magnetic steel power sampling method and puncture power sampling method. Current sampling: Equipped with an open type current transformer, it supports sampling from primary cables or existing 5A secondary current circuits.
