The digitization of the energy industry is the basis for smart energy management and thus also for the energy revolution. Here, a basic building block is the smart recording of heat, water, electricity and gas consumption data. The so-called smart metering requires a modern measuring technique and corresponding transmission technologies. This includes the wireless Meter-Bus(wM-Bus), which allows for the central reading of all consumption data almost in real time. This is a fieldbus, meaning a technology which connects fields devices, such as measuring sensors, with automation devices. Here, you can find a detailed explanation on the functioning of the wireless M-Bus. In the following article, we focus on the use of transmission technology in the energy industry, in particular for submetering.
Requirements of the consumption data acquisition for transmission systems:
The collection of consumption data in the energy industry places specific demands on the technologies used. Usually, a large number of devices have to be connected to each other, and often over comparatively long distances.
Given that the collected data is used, among other things, for cost reporting, it is vital that both the collection and transmission of data are guaranteed to be reliable and error-free at all times. Thus, transmission systems used must not be susceptible to external disturbances, as much as it is possible.
Given that the information quantity per transmission is usually quite small, a low transmission speed is sufficient. In addition, the installation and operation should be cost-effective and simple, as much as it is possible.
Application focus submetering:
One of the main application fields for the wireless M-Bus technology is in the housing industry. Landlords or owners can determine the individual consumption of water, gas, or electricity, for each tenant. This is used especially in large buildings with several residential units, such as student dormitories or also office complexes.
This type of consumption data acquisition is known as „submetering“, because there is no direct business relationship between the end customer and the utility supplier: for example, the homeowner purchases water from the utility company and is also charged for it (metering). Then, these costs are passed on to the tenants, through submetering, depending on the individual consumption. These only have a direct business relationship with the landlord.
In addition to this method of recording actual consumption per household, the term submetering also refers to determining the proportional consumption of individual appliances and applications, such as a refrigerator or outdoor lightning.
In addition to the classic smart metering applications for the recording of energy and water consumption, wM-Bus is today also often used for the digital recording of heating costs in particular. Here, the transmission technology allows for the seamless collection of all consumption data, which is essential for the correct billing.
The transmission of consumption data via wireless M-Bus meets the above-mentioned requirements, and offers a reliable and secure connection of many devices, at a comparatively low cost. In this article you can read how the functionality of the wireless M-Bus ensures this exactly. In addition to the other classic mobile-based transmission standards, the M-Bus also enjoys great popularity in the energy industry, due to being able to match these requirements.
