Definitions
- the object of this invention is to eliminate these drawbacks, namely, to create a meter providing supply of electrical energy after pre-payment, the said meter being reasonably priced and ruling out the possibility of fraudulent use of electrical energy. Disclosure of the Invention
- the current parameter sensor can be equipped with a shunt (instead of the transformer) coupled with the linear pulser whereas
- the meters are made with placement in the central cabinet and in personal cabinets (one for each customer),
- the central cabinet houses the components serving all customers and a transmitter-receiver
- Fig.1 block diagram of the base variant of the proposed meter.
- Fig.2 block diagram of the meter, with analog-to-digital converter and current transformers of the current parameter sensors.
- Fig. 3 - fragment of the block diagram of the meter with current transformer of sensor, linear pulser and pulse counter.
- Fig.4 fragment of the block diagram with the shunt of the current parameter sensor, linear pulser, optical circuit separator, and pulse counter.
- Fig.5 diagram of the positioning of the meter's main parts when the customers are spaced widely from each other.
- the outputs of sensors l] ⁇ l n are connected to the inputs of multiplexer 2, its outputs coupled to microprocessor 3 for consecutive reading by said microprocessor of sensor indications (indications of binary counters whose number is equal to the number of customers) and recording the results in non-volatile memory (capable of storing the latest indications even in the event power is cut off).
- general command unit 7 is connected to microprocessor 3 ; said command unit being essentially a decoder from binary to position code and an amplifier ensuring output current sufficient for the normal functioning of the relay (or semi-conductor switch) 8 connected to the circuit of the amplifier, said relay (or semi-conductor switch) meant to connect to the power network each customer who has credit for electricity and disconnect from the power network each customer who has used up his credit for the preset amount of electricity. All in all, the meter has (n) relays or switches 8j ⁇ 8 n for each customer using the meter.
- Said pulser 12 one for each customer, is intended to transform the digits, in which incoming electricity is counted, into consecutive pulses of set duration coming at a rate proportional to the active power values (corresponding to incoming electrical energy).
- the central cabinet houses the components serving all customers (specifically functional elements 1, 3, 4, 5) and transmitter-receiver 18, - personal cabinets 17:
- the current parameter sensor is also placed on the input of the central cabinet.
- the meter has an ala ⁇ n device for customer cut off in case the difference between the amount of energy entering the meter and the amount of electrical energy fixed by the sensors in the personal cabinets over the same period of time exceeds the preset value.
- Each of the cabinets described herein has a device for giving a sound signal, disconnecting the customer from the power network and transmitting the alarm signal to the power supplier if a cabinet is opened (tampered with) by unauthorized persons, and meters (or a section of the network controlled by a meter) is broken into.
- the meter operates as follows:
- the microprocessor uses the receiving unit to record in the appropriate memory cell the sum pre-paid by the customer and his tariff rate. After that the microprocessor activates the relay (or the semi-conductor switch, which is its non-contact equivalent) and thus opens power supply to the customer who has made the pre-payment.
- the customer can at any moment verify how much credit is still available to him by inserting the smart card into the meter: after this action the microprocessor transfers to the display the amount of the available credit stored in the memory cell of this customer.
- information can be transmitted with low frequency. It allows to transmit information from sensors to microprocessor via multiplexer, using transmitter-receivers even if the meter components are placed in different (central and personal for each customer) cabinets located at a considerable distance from one another.
- the said function of preventing fraudulent use of electricity is performed by transmitting to microprocessor the information about the amount of electricity that has entered the meter input and the total amount of electricity recorded by the sensors in personal cabinets over a definite period of time and subsequently comparing these two values. If electricity has been stolen, the difference between said measured values will be above the permissible level, which will activate the abovesaid system.
