Shanghai will realize wireless smart meter reading in 5 years

According to statistics, more than 1 million Shanghai residents have enjoyed this “wireless smart meter reading” service this year since China Mobile Shanghai Co., Ltd. and Shanghai Electric Power Co., Ltd. launched the “Wireless Meter Reading” project last year. It is expected that in the next five years, more than 8 million households in the city will implement wireless meter reading. By then, it is not difficult to obtain information on the use of home appliances anytime and anywhere.

It is reported that after the electricity collection is conducted in the second half of this year, the meter of the 1 million users will not need meter readers to read the meter, saving about 1/8 of the total amount of manpower. After the full implementation of wireless meter reading, the power department will collect data on the user's daily power consumption, and the user will be able to more accurately know the power consumption of his/her home.

The so-called "wireless smart meter reading" means that the digital power meter first communicates with the power meter through the power carrier and collects the user's meter data to the concentrator. The concentrator can send data to the monitoring center in real time through the mobile GPRS wireless module, and the monitoring software can perform data on the data. Summary processing. In the era of “wireless smart meter reading”, meter data can be transmitted to the power sector in a timely and accurate manner, solving the current situation of China’s electricity meter reading field, including miscalculation, missed copying, misprinting, and missed meter readings. The inefficiency of the table.

As we all know, electricity, as an indispensable source of energy in human society, must be spread all over the place where human beings are located. Therefore, the user's electricity meter has a wide range of distribution characteristics. The traditional manual meter reading consumes a lot of manpower and time, and there are problems such as inaccurate, untimely, and uncontrollable. If all of the meter data are recorded by cable, the cost of input is very high.

The wireless network has a wide coverage area and supports real-time transmission, which just meets the requirements of real-time data collection and transmission in the power sector. Through the wireless meter reading system of the power department, not only can accurate, centralized, and time-stamping records of electricity consumption of each user, but also provide reliable electricity data, line loss statistics, power grid load and other information, improve the level of power monitoring, greatly Improve the power company's work efficiency and management level. During the peak period of power usage, the power supply department can also adjust the peak-to-peak adjustment of real-time data to change the working methods that were previously judged only by experience, and management services are more scientific and sophisticated.

It is understood that in the next five years, Shanghai will build a wireless intelligent power consumption information collection system covering all urban and rural residents. After the system is completed, the relevant managers can use the computer mouse to gently click on the system to complete the daily work of meter reading data entry and printing. By then, it will realize the real-time collection and intelligent remote real-time information collection of 8 million households. The two-way interactive electricity service and other functions establish a smart electricity service system.

The reporter learned that since the meter itself has a certain period of use, the new meter will be replaced by the number of years of arrival. Therefore, 1 million households are gradually replacing. The plan to cover 8 million families in the next five years is also implemented step-by-step, with an average of about 20% of the total annual completion within five years. Since the meter itself needs to be replaced on a regular basis, there is not much increase in the input to it and the residents will not incur additional costs.

It is reported that at present, the State Grid has implemented a wireless meter reading system throughout the country. Like everywhere in Shanghai, it plans to complete the goal of full coverage of “wireless smart meter reading” within five years.
