Problems solved by technology

[0004] The existing meter reading method only reads the accumulated power consumption of the meter, and cannot read the power consumption of a specific time period, such as querying the power consumption from 1:00 am to 4:00 am afterwards
In addition, the existing meter reading method does not care about the real-time power consumption and its changes, for example, the alarm cannot be output immediately when the power consumption exceeds a certain value

Embodiment 1

[0060] If the external device wishes to query the hourly electricity consumption in the future, the length of the recording period is set to 1 hour through wireless communication. When the data needs to be accessed, the power consumption data in the memory of the device is read through wireless communication.

Embodiment 2

[0062] The external device wants to cut off part of the load when the power consumption is greater than 5kW, and check whether the actuator is working normally. Then the alarm event 1 can be set as the power is greater than 5kW through wireless communication. Once the wireless meter reading device calculates that the current power is greater than 5kW, it will immediately trigger an alarm and send an alarm signal through wireless. After receiving the alarm signal, the external equipment controls the relay and cuts off part of the load. Then read whether the current power value drops to a predetermined value through wireless, so as to achieve the purpose of closed-loop control.

Embodiment 3

[0064] The external device wants to do linkage control, when a certain electrical appliance A is turned on, the electrical appliance B is started. It is known that the power of A is 1000W, and the power of B is 100W. Then the alarm event 2 can be set as power transient +1000W through wireless communication. If the current power is 800W, when the power value is 1800W instantaneously, the wireless meter reading device triggers alarm event 2 and sends out an alarm signal through wireless. After receiving the alarm information, the external device controls and starts the electrical appliance B. The external device can also read whether the current power value is within the theoretical 1900W.

[0065] In addition to the power transient can be set as a positive transient value, it can also be set as a negative transient value.

Description

technical field [0001] The invention relates to a wireless reading device for electric meters, in particular to a wireless reading device for electric meters which is safe and convenient to install, and can output various alarm events. Background technique [0002] The electricity meter is a measuring instrument for electricity consumption, and its output information includes important information such as current electricity consumption and electricity consumption. By reading the information output by the meter, it is very important for us to use electricity safely, save electricity, and intelligently control it. [0003] Most of the electric meter reading devices proposed in the prior art are based on the RS485 bus, and the reading devices also need external power supply. This requires wiring during installation. For non-engineering technicians, it is difficult to implement, and there are major safety hazards such as contact with strong electricity leading to electric shoc...
