A sim card testing device

Abstract

The invention discloses a SIM card testing device. The device includes a communication unit, a SIM card identification unit, a mechanical unit, a control unit and a power supply; the mechanical unit includes a wedge-shaped base; a storage box, the storage box is provided with a partition, and the partition divides the storage box into two storage areas; One side is provided with a first baffle and a second baffle, and the first baffle slides relative to the second baffle along the groove on the storage box under the drive of the traction structure; There is a gap on the side of the storage box close to the second baffle, and a transmission structure is arranged in the gap; the SIM card identification unit is electrically connected to the SIM card to be tested; the communication unit is used to upload the information of the SIM card to be tested to the main station, and receive the test result generated by the master station; the control unit is used to control the transmission structure according to the test result, so that the transmission structure puts the SIM card to be tested into the corresponding storage area. The invention can realize uninterrupted automatic test on the SIM card and improve the test efficiency of the SIM card.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of mobile terminal applications, and in particular to a SIM card testing device. Background technique [0002] At present, the communication between terminal equipment such as load control, distribution transformer and concentrator of power grid enterprises and the main station needs to realize remote data interaction through SIM card and wireless public network. The quality of the SIM card determines whether the information can be effectively transmitted, and its importance is self-evident for power supply companies that need to grasp the electricity consumption information of millions of users in real time. Every year, the power supply company purchases nearly 10,000 SIM cards from the three major operators, and there are usually three types of problems due to the reasons of the operators: First, batches of unactivated SIM cards are issued by mistake, and these SIM cards cannot lo...

Problems solved by technology

Every year, the power supply company purchases nearly 10,000 SIM cards from the three major operators, and there are usually three types of problems due to the reasons of the operators: First, batches of unactivated SIM cards are issued by mistake, and these SIM cards cannot log in to the main station. The failure to get the card and go to the site to install the card, you need to come back again to change the card, resulting in a lot of waste of manpower and material resources; second, although the SIM card is activated, there are data reading and writing errors or incomplete data uploading, which affects power metering and later copying. The third is that the SIM card body is defective and cannot be used

[0003] However, the existing SIM card testing method can only test a single SIM card, and it takes several minutes for a SIM card

At present, the annual inspection volume of SIM cards in general prefectural and municipal power supply bureaus reaches tens of thousands. Due to time constraints, only a small number of samples can be taken for testing. Manual inspection is inefficient, resulting in waste of labor costs, and in case of failure to detect abnormal SIM cards The installation of the card to the site will lead to a decrease in the meter reading rate, and it is necessary to re-apply, receive the card, and install it, which increases a lot of unnecessary workload
