Portable on-site comparison detector for electricity user information sim card data

Abstract

The invention discloses a portable in-field comparison detector for data of a power user information SIM (Subscriber Identity Module) card. The portable field comparison detector comprises a rectangular insulation box body, a liquid crystal display screen, a base and a circuit board. The portable field comparison detector is characterized in that antiskid handles, which are inwards sunken, are arranged on two sidewalls at the middle lower part of the rectangular insulation box body, a card slot seat of a standard SIM card and a card slot seat of an SIM card for in-field use are arranged on the front plate surface of the antiskid handles, and the corresponding SIM card is inserted and is converted by a switching chip; a charging socket, a switch, a power indicator lamp and a status indicator lamp capable of judging whether the SIM card for in-field use is qualified are arranged on the front plate surface of the base. According to the portable in-field comparison detector for the data of the power user information SIM card, the SIM card for in-field use and the standard SIM card are compared in one machine so as to rapidly judge whether the SIM card for in-field use is qualified, and furthermore, the portable field comparison detector has the advantages of simple structure and convenience for use and carrying, and can be widely used for in-field detection of the power user information SIM card.

Description

technical field [0001] The invention relates to a SIM card data detection device, in particular to a portable on-site comparison detector for electricity user information SIM card data capable of timely comparison and detection of SIM cards used by electricity users. Background technique [0002] SIM card is a kind of user identification card, the chip in which stores mobile phone, customer information, program storage, data storage, work storage and serial communication unit, which can be used for identification of GSM network customer identity, and has been widely used in communication and In various remote payment fields, the quality of the SIM card issued by the communication company is an important issue to ensure that the communication is correct and reliable. Therefore, in order to ensure the quality of the SIM card is qualified, it is necessary to test the SIM card before issuing it. It can be seen through retrieval that at present, Chinese patent 200620078068.2 disc...

AI Technical Summary

Problems solved by technology

Because in the power supply system, the application of the SIM card has certain particularities: First, the network does not use the general public network access, but the VPN private network access, and the settings of the VPN private network using the power supply company are different from those of general terminals ; Second, the site installation of terminal equipment is widely distributed, and the causes of communication failures are complicated. It is often encountered that the public network APN can be accessed normally, but the VPN private network cannot be accessed; the third is affected by the network in different locations, the access speed different speed

Because of the above particularities, although the SIM card issued by the communication company has no quality problems, it cannot be used normally in the user's electricity consumption information collection system.
