Description

A split-type smart energy meter

technical field

The utility model relates to the field of electric energy meters, in particular to the technical field of split type intelligent electric energy meters.

Background technique

The energy meter is an instrument used to measure electricity. In addition to the energy measurement function, the smart energy meter also includes functions such as data processing, data communication, billing, data storage, and data display.

At present, my country's smart energy meters are all integrated designs, and the hardware structure design is relatively solid. A single PCB design is adopted, and all functions of the energy meter are on one PCB.

With the promotion of tiered electricity prices and electricity price competition among power supply companies in my country, the billing method will be adjusted frequently; once the billing method is adjusted, the entire electric energy meter needs to be replaced, which not only increases the maintenance cost, but also causes a waste of resources. When the smart energy meter fails, the entire energy meter can only be replaced to ensure the smooth progress of the power metering work. The higher probability of failure is some other functions except the metering function. Moreover, as the requirements for smart energy meters increase, software for certain functions needs to be upgraded or replaced. For the current situation, only the entire energy meter can be replaced, and some functional modules cannot be upgraded or replaced individually.

Utility model content

The technical problem to be solved by the utility model is to provide a split-type intelligent electric energy meter with a pluggable and replaceable management module in view of the status of the prior art.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a split-type intelligent electric energy meter, which is characterized in that it includes a base meter of the electric energy meter, and a slot is arranged on the base meter of the electric energy meter, and the management module The slot is detachably installed on the base meter of the electric energy meter.

The management module is provided with a display screen, buttons and an IC card slot. The display screen is used to display data, the keys are used for system operation, and the IC card slot is used to insert an IC card.

The upper part of the management module is provided with a communication slot, and the communication module is removably installed on the management module through the communication slot. In this way, the communication module can be plugged and replaced, not only can be directly replaced when a failure occurs, but can also be reused when replacing the management module.

There are two communication modules, one of which is an uplink communication module and the other is a downlink communication module.

When the power fails, it provides working power for the management module, and the second-stop battery is also installed on the management module.

The base meter of the electric energy meter is also provided with an hour hand power supply.

A protective cover is arranged above the communication module. The upper protective cover protects the communication module and plays the role of waterproof and dustproof.

The lower end of the base meter of the electric energy meter is provided with a terminal base connected thereto, and a lower protective cover is arranged under the terminal base, and the lower protective cover is mounted on the terminal base. The lower protective cover protects the terminal block and plays the role of waterproof and dustproof.

A hanging ring is arranged on the back side of the base meter of the electric energy meter. The hanging ring facilitates the fixed installation of the energy meter on the wall.

The management module of the utility model is detachably installed on the base meter of the electric energy meter through the slot, so that the management module can be separated from the electric energy meter base meter with metering function; when the management module breaks down or the software is upgraded, it only needs to be replaced The management module is enough, and the entire energy meter does not need to be replaced, which not only reduces maintenance costs, but also saves maintenance time. Moreover, the communication module is pluggably installed on the management module, which realizes pluggable and replaceable communication modules, and further reduces maintenance costs.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1, Fig. 2 have shown a kind of embodiment of the present utility model, and it comprises electric energy meter base table 10, and this electric energy meter base table 10 is provided with slot 13, and this slot 13 is connected with the electric circuit of electric energy meter base table inside. board electrical connection. The electric energy meter base 10 is composed of a front case 11 and a rear case 12 , and a slot 13 is arranged in the middle of the front case 11 . The management module 20 is removably installed on the electric energy meter base 10 through the slot 13 . The management module 20 is provided with a display screen 21 , buttons 22 and an IC card slot 23 . The base meter of the electric energy meter is mainly used for power measurement, the display screen is used to display data and operation data, the system operation is realized through buttons, and the IC card slot is used to insert the IC card.

The base meter of the electric energy meter is mainly responsible for power metering. The management module is used to realize functions such as display, system operation, IC card, and communication. . When the electric energy meter needs to upgrade the software, expand the function or the function on the management module breaks down, just unplug the original management module and replace it. Not only save maintenance cost but also save maintenance time.

Also installed stop reading battery 24 on the management module 20, this stop second battery 24 is embedded on the management module, and this stop reading battery can provide operating power for the management module during a power failure, and the stop second battery is a rechargeable battery and is removable.

There are two communication modules 25 arranged above the management module 20, one of which is an uplink communication module and the other is a downlink communication module.
