4G wireless smart meter reading, more than a little easier!
4G wireless smart meter reading, more than a little easier!
With the development of the Internet of Things, people's lifestyles are changing subtly, and work and life are gradually shifting from traditional offline to online. More and more companies are also adopting offline and online management models to improve LoRa technology business Viability and competitiveness, meter reading is no exception.
In daily property management, meter reading is a tedious task, and the traditional meter reading mode has many disadvantages:
1. Manual meter reading is troublesome and error-prone
2. Dispersion distance is long and time-consuming
3. The efficiency is too low and the labor cost is too high
Aiming at the defects of the traditional meter reading method, the 4G wireless smart meter reading system came into being. Based on the 4G communication technology of the three major operators, it has the advantages of fast transmission speed, low communication cost, convenient installation and low cost, no need for additional wiring, and stability. Strong, not limited by distance and many other advantages, the use of 4G wireless meter reading solution can effectively reduce labor costs and improve the accuracy of data statistics.
Ebyte EC04 module is perfectly suitable for 4G wireless smart meter reading system. This module has the following advantages:
1. Not subject to regional restrictions: adopt CAT1 solution, support 4G full Netcom, wide coverage, high stability, low delay, and can be applied to various environments, such as mountainous areas, towns and other areas with underdeveloped traffic;
2. Support multiple working modes: network transparent transmission (TCP/UDP), MQTT mode, HTTP mode, SMS transparent transmission, customers can choose the desired transmission mode;
3. Support quick access to Alibaba Cloud, Baidu Cloud, onenet and version 3.1 standard MQTT servers, and can quickly access the MQTT servers built by customers to realize data uploading to the cloud;
4. Support multi-link edge acquisition, support modbus automatic CRC check, and can automatically convert the collected modbus data into modbus tcp;
5. The module is small in size, easy to install and convenient for wiring.
Thanks to these features, the EC04 module connected to the meter can transmit data to the server through the 4G network. After configuration, it can be used after power-on, and the operation is convenient. This can save the cost of arranging communication lines and save Labor costs.
The 4G networks of the three major operators cover the whole country, so the EC04 module can receive meter reading data from various places without distance restrictions, and realize the effect of centralized management of multi-place meters by one server. If customers have control needs, the EC04 module can also Realize remote control of the meter, no matter which region or city the meter is installed in, as long as there is a signal at the location of the meter, remote control can be realized, such as the timing switch of the meter according to customer needs.
