Description
技术领域Technical field
本发明涉及计费电能表技术领域，特别涉及一种具有远程控制电磁式计费封印的电能表。The invention relates to the technical field of billing electric energy meters, and in particular to an electric energy meter with a remote control electromagnetic billing seal.
背景技术Background technique
目前电能表的计费封印还停留在普通铅制封印的层面上，其是一个铅块将表的接线口封装的装置，以避免被其他人员打开。此类封印表面印有编码，以便经营人员查询及检查。At present, the billing seal of electric energy meters is still at the level of ordinary lead seals. It is a device that seals the wiring port of the meter with a lead block to prevent it from being opened by other personnel. There is a code printed on the surface of this type of seal to facilitate query and inspection by operators.
目前，电力计费封印实行计费封印的领取人签字制度，对封印被领取后，谁安装的，谁报废的，安装在哪都记录在工作记录本上，显然这种管理方式低效且落后，想要查询某一枚封印时恐怕要动用大量的人力和时间成本。At present, the electricity billing seal adopts the signature system of the recipient of the billing seal. After the seal is collected, who installed it, who scrapped it, and where it was installed are recorded in the work record book. Obviously this management method is inefficient and backward. , it may take a lot of manpower and time to query a certain seal.
落后的设备也为窃电行为埋下了伏笔，比如窃电的手段很多情况为破坏计费用的封印对计量装置做手脚，并用新的封印替代，因此仅仅从封印外观的完好程度来判断是否存在窃电行为显然不可靠。Outdated equipment also paved the way for electricity theft. For example, the method of electricity theft in many cases involves destroying the fee seal, manipulating the metering device, and replacing it with a new seal. Therefore, the integrity of the appearance of the seal can only be used to judge whether the electricity is stolen. The existence of electricity theft is obviously unreliable.
公开号为CN 206906449 U的中国专利提出了一种用于电表的智能封印，采用封丝，并且通过电路判断封丝是否断线来判断封印是否被打开。这种封印仅具有封印报警功能，但是没有远程封印和解封功能。The Chinese patent with publication number CN 206906449 U proposes a smart seal for electric meters, which uses a sealing wire and uses a circuit to determine whether the sealing wire is broken to determine whether the seal has been opened. This seal only has a seal alarm function, but does not have a remote sealing and unblocking function.
