Integrated Circuit, specific integrated circuit), (Field-Programmable Gate Array, scene can compile FPGA
Journey gate array) or CPLD (Complex Programmable Logic Device, Complex Programmable Logic Devices) in it is any
A kind of processor.
Common SIM card generally has two kinds of specifications of 6 pins and 8 pins.Shown in Fig. 3, by taking the SIM card of 6 pins as an example, provide
Circuit connection diagram between reader 203 and the SIM card 30 being strobed, for the convenience of description, read-write is omitted in Fig. 3
Peripheral logical circuit 202 and interface circuit between device 203 and SIM card 30, wherein SIM card 30 include the contact power supply VCC 301,
Reset the contact RST 302, the contact clock CLK 303, the contact ground terminal GND 304, the contact program voltage VPP 305 and data I/O touching
Point 306.Write the process of card are as follows: business personnel write by terminal the operation of card, and terminal is written into data distributing to read-write
Device 203；Reader 203 is powered on by the contact power supply VCC 301 to SIM card 30, then tranmitting data register signal to the contact clock CLK
303, the corresponding signal of data to be written is then sent to the contact data I/O 306, is written into data write-in SIM card 30, is completed
Stop after data write-in to the power supply of the contact power supply VCC 301.
Write snap past Cheng Zhonghe and write card after the completion of, 203 output end of the reader (end being connect with peripheral logical circuit 202
Mouthful) output signal can change, therefore, control chip 204 by monitoring reader 203 and peripheral logical circuit 202 between
The state change of the pin of connection, it is determined whether completed writing operation, and automatically switched after determining completion writing operation
Next card slot 201.
For example, as shown in figure 4, an input pin of control chip 204 can be with the first pin in peripheral logical circuit 202
2021 connections, the first pin 2021 are the pin being connected in peripheral logical circuit 202 with the power supply output pin of reader 203,
Control the level state of 204 the first pin of real-time monitoring 2021 of chip.When writing card, the power supply output pin of reader 203 is exported
High level is to the contact VCC 301, and to power on to SIM card 30, and after the completion of writing card, the power supply of reader 203 stops the high electricity of output
It is flat, therefore, when control chip 204 monitors the variation of the level state generation of the first pin 2021 from high to low, illustrate
Through completing the writing operation to the SIM card currently gated, at this point, control chip 204 control peripheral logical circuit 202 gate it is next
A card slot 201 can be realized the function of automatically switching SIM card, promote the operating efficiency of business personnel.

The place of setting is additionally provided with a work light 502, by the card slot 201 of the instruction gating of work light 502, for example, the card of gating
The corresponding work light 502 of slot 201 can be lit, and the corresponding work light 502 of card slot 201 that remaining is not gated on is put out
It goes out, business personnel is allowed to know the position of the SIM card currently gated at a glance.
Wherein, each work light 502 can directly be connect with control chip 204, light choosing by controlling chip 204
The logical corresponding work light 502 of card slot 201.Each work light 502 can also be connect with peripheral logical circuit 202,
When peripheral logical circuit 202 gates a certain card slot 201, so that the corresponding work light 502 of card slot 201 of the gating and confession
Power supply is connected, to light the work light 502.
As shown in figure 5, being additionally provided with a malfunction indicator lamp at the corresponding position of each card slot 201 in equipment cabinets 501
503, the card slot 201 to break down is indicated by malfunction indicator lamp 503, for example, the corresponding malfunction indicator lamp of failure card slot 201
503 can be lit, and the normal corresponding malfunction indicator lamp 503 of card slot 201 is extinguished, so as to business personnel's timely learning failure card slot
201, it selects normal card slot 201 to handle related service, improves the efficiency of processing business.
Wherein, each malfunction indicator lamp 503 can directly be connect with control chip 204, by controlling 204 brighten the hairs of chip
The corresponding malfunction indicator lamp 503 of card slot 201 of raw failure.Each malfunction indicator lamp 503 can also pass through peripheral logical circuit 202
It is connect with reader 203, corresponding malfunction indicator lamp 503 is lighted after getting the fault-signal issued by terminal.
Compared with existing single deck tape-recorder reader, multichannel SIM card read-write equipment provided in this embodiment is had the advantage that
(1) due to being provided with multiple card slots for placing SIM card, business personnel can fulfil the filling of SIM card ahead of schedule, busy
