Description

Technical Field

[0001] The utility model belongs to the technical field of electric energy meter production, and in particular relates to a device which is compatible with infrared communication and can detect metering pulses of electric energy meters. Background Art

[0002] In view of the purpose of reducing costs for overseas electricity meters, the pulse output auxiliary terminal part is removed from the current and voltage terminals. At present, the commonly used method for detecting the metering error of the electricity meter is to obtain the metering pulse of the electricity meter by sampling the pulse LED indicator light with a photoelectric head. For the inspection equipment with multiple meter positions, each meter position needs to be equipped with a photoelectric head, and the equipment cost is relatively high. Another method for detecting the metering error of the electricity meter is to obtain the test pulse of the electricity meter using the reserved interface inside the electricity meter without adding a meter cover, so as to calculate the metering error of the electricity meter in the electricity meter inspection device. This method requires the decomposition of the structural assembly process and the connection of other adapters. This method brings inconvenience to the subsequent factory inspection after adding the meter cover. In addition, overseas electricity meters generally use near-infrared communication. This communication method requires the communication connector to be close to the adsorption iron sheet on the electricity meter before communication can be achieved.

[0003] Therefore, there is a situation where the infrared communication connector is used for communication and the photoelectric head is used for debugging or detecting the measurement error of the electric energy meter at the same time. In such a case, there will be physical interference between the infrared communication connector and the photoelectric head or inconvenience in operation. At the same time, the test lines are increased and complicated. Each meter position needs to be equipped with a photoelectric head and an infrared communication connector at the same time, and the equipment cost is high. Therefore, a device that is compatible with infrared communication and can detect the measurement pulse of the electric energy meter is needed to help solve this problem. Utility Model Content

The error debugging production efficiency and inspection and detection efficiency of the electric energy meter are greatly improved, thereby improving the production capacity of the electric energy meter after the subsequent production of the electric energy meter.

[0026] A female head is provided at one end of the PC communication structure 1 away from the wire cable 3, and a male head is provided on the PC for plugging into the female head on the PC communication structure 1, and the female head and the male head are plugged in together.

[0027] An adsorption head 7 is arranged at one end of the infrared detection head 6 away from the wire cable 3. The adsorption head 7 is in a circular ring structure. An adsorption ring is embedded and installed inside the adsorption head 7. The adsorption ring cooperates with the dial on the electric energy meter for adsorption.

[0029] Working principle:

[0030] During operation, the female head on the PC communication structure 1 is plugged into the male head on the PC, and the fastening bolt 2 is turned so that the fastening bolt 2 and the threaded hole are threadedly matched, so that the PC communication structure 1 is clamped and installed on the male head of the PC through the fastening bolt 2, and the metering pulse output plug 5 is plugged and installed on the pulse input socket, and the adsorption ring on the adsorption head 7 is adsorbed with the dial on the electric energy meter. During detection, the GPIO working mode corresponding to the infrared receiving tube is the ordinary GPIO input mode, and it is used to receive the signal sent by the electric energy meter, and a certain judgment mechanism is used to judge whether the waveform of the signal within a certain period is a pulse signal with a pulse width of 80ms. If it is confirmed to be such a signal, the signal is sent to the error input port of the inspection equipment.

[0031] When the PC software uses the device to send data to the electric energy meter, the GPIO working mode corresponding to the infrared receiving tube is switched to the serial port receiving mode, ready to receive the message responded by the electric energy meter. When there is no data interaction between the PC software and the electric energy meter within 30 minutes (this time is programmable), the GPIO working mode corresponding to the infrared receiving tube will automatically switch back to the normal GPIO input mode. The technical implementation block diagram is as attached to the manual. Figure 5 shown.
