Advantages of Remote Prepaid Electricity Meter
The remote prepaid electricity meter is mainly used for the metering of the school's student apartment to meet the school's safe electricity demand. The instrument adopts liquid crystal display, and has the functions of active energy measurement, modulation infrared communication, 485 communication, remote control of power off, automatic freezing of daily power consumption during meter reading, and real-time monitoring.
It transmits its electric energy and other data to the computer client by means of GPRS communication, which is an ideal choice for electricity consumption in student apartments and remote meter reading. The installation is simple, the implementation is convenient, the maintenance is simple, and the expensive labor management cost is saved.
Disadvantages of traditional card prepaid energy meter:
The card-type pre-purchase electricity system solves the problem of difficult charging, but there are still the following shortcomings:
(1) The collection of electricity consumption data is not timely enough. If you don't send someone to read the meter, the user's electricity consumption can only be transmitted when the user purchases electricity. The data has a lag, and it is difficult to realize the actual electricity consumption statistics and line loss calculation.
(2) When the electricity price is adjusted in accordance with the relevant national policies, for the power supply enterprise, although it is possible to limit the hoarding of electricity, but still adopt the pre-sale electricity price settlement after the price adjustment, which will cause certain losses to the power supply enterprise or customers.
(3) Real-time monitoring and management cannot be carried out, and problems cannot be detected and dealt with in a timely manner. Once electricity metering errors occur, it is easy to cause electricity bill settlement disputes between the power supplier and the electricity user.
The necessity of using a prepaid energy meter:
1) Ensuring the recovery of electricity bills is the primary task of power supply enterprises' marketing. The recovery of customer electricity bills is the top priority of the marketing of power supply companies. Pre-purchasing electricity among tenants or customers with low reputation can effectively reduce the risk of recycling.
(2) Rich payment methods, customers can pre-purchase electricity according to electricity demand. There is no need to pay the prepaid electricity bill every month according to the fixed amount of electricity agreed in the contract as in the past, which reduces the backlog of funds and is convenient and time-saving.
(3) Avoid policy risks. When adjusting the electricity price, the manager can convert the remaining electricity and issue it again, avoiding the loss of power supply enterprises or customers.
(4) At present, the measures of power rationing or power outage are taken to customers in arrears, and the way of installing pre-purchased power devices on the user side requires large investment and heavy work tasks.
(5) On the basis of marketing system, metering automation system and demand-side decision-making management and analysis system, it is necessary to realize the function of pre-purchasing electricity and the research on remote reading and control of pre-paid electric energy meters without increasing investment in hardware equipment.
