IoT based smart energy meter

Abstract: Energy meter reading is a tedious and an expensive affair. The meter reader has to go and take the reading manually to issue the bill, which will later be entered into the software to automate the billing and payment system. This paper proposes a new network communication system for energy meter reading by internet communication technology and software system along with the existing meters. An IoT modem will be integrated with electronic energy meter to read the usage of electricity and uploaded on server or website. Energy meter delivers the reading details and it is uploaded to the website instantly. This communication system is further useful for electricity regional/sub-regional office, who can monitor the power consumption, and they cut the power supply for any specific house, who had not paid the electric bill using the EB Office Login. Moreover, this power cut control system is done by using the same website which is used for monitoring. In this project each customer is differentiated using address or ID, this ID is used for identification by the consumer and as well as my office to monitor the reading and payment details. The user can also monitor their usage from anywhere using the user login. An additional feature is provided to the user for controlling the power supply during in terms of emergency case.

Tamper detection apparatus for electrical meters

Abstract: Tamper detection apparatus for an electric meter (M) installed at a facility supplied power through an electrical distribution system, the meter being connected to the facility using a receptacle (K) and monitoring electricity usage at the facility for electricity delivered to the facility flowing through the meter. A sensor (RR) senses movement of the meter more than a predetermined amount with respect to the receptacle, whether or not electricity is flowing through the meter, and produces a tampering signal when this occurs. A second and optional sensor (Z) senses the proximity of the meter to its receptacle with removal of meter from its receptacle producing a tampering signal representative thereof. Generation of a tampering signal results in a tamper alert signal being transmitted to the system through a two-way communications path established between the facility and the system.

Consumption breakdown monitoring through power state sensing

Abstract: Systems and methods are provided for estimating power breakdowns for a set of one or more appliances inside a building by exploiting a small number of power meters and data indicative of binary power states of individual appliances of such set. In one aspect, a breakdown estimation problem is solved within a tree configuration, and utilizing a single power meter and data indicative of binary power states of a plurality of appliances. Based at least in part on such solution, an estimation quality metric is derived. In another aspect, such metric can be exploited in a methodology for optimally placing additional power meters to increase the estimation certainty for individual appliances to a desired or intended level. Estimated power breakdown and energy breakdown—individually or collectively referred to as consumption breakdown—rely on measurements and numerical simulations, and can be evaluated in exemplary electrical network utilizing binary sensors.

An IoT Based Smart Energy Management System

Abstract: Physical energy meter reading is an outdated concept, it is inefficient, prone to errors and leads to a lot of wastage of manpower and is a burden on the consumers since the energy companies pass on the cost of physically reading the meters to the consumers. Smart energy meters solve the above-mentioned problems to a great extent but replacing the older energy meters is a very expensive and a humongous task. This paper introduces an IoT based smart energy meter using the raspberry pi devices as a solution to the aforementioned issue. A small modification to the already installed old meters can make them act as prepaid smart meters. So, the need to replace the old energy meter does not arise. These meters can be easily accessed through customized web pages, smart mobile applications and relevant notifications can be sent to the customers using SMS service. These meters can be turned ON and OFF automatically once a user exhausts its prepaid threshold value or through the smart App. Consumers are notified through SMS when the threshold set value is about to breach.
