After function, tester can carry out some manually test or automatic tests according to the equipment of connection.
In above-mentioned peripheral equipment, main equipment be connected by a USB control interface with STM32 series monolithic to
The control work to peripheral equipment is carried out, so that USB is controlled, SD, the communications and liaison of SIM card.
Following table is the parameter comparison table of main equipment and STM32 series monolithic USB interface:
The parameter comparison table of 1 main equipment of table and STM32 series monolithic USB interface
| Contact | Function (main equipment) | Function (STM32 series monolithic) |
| 1 | VBUS (4.75-5.25V) | VBUS (4.4-5.25V) |
| 2 | D- | D- |
| 3 | D+ | D+ |
| 4 | Ground connection | Ground connection |
By connecting a switch in VBUS line, by control equipment pin export high level to a high level triggering after
Electric appliance, relay control the communications and liaison simulation USB plug of USB VCC, computer can correctly be identified and off device.
USB hot plug principle:
USB includes tetra- lines of VBUS, D+, D-, GND,
D+, D- of the USB of computer end has a pull down resistor,
When USB insertion, due to the presence of pull-up resistor, divided by the pull-up resistor of 1.5K and the pull down resistor of 15K,
Two want have to be pulled to a high level in signal wire, and after hub detects this state, it is reported to USB host controller
(or being reported by its upper one layer hub to USB host controller), is detected by inserting for equipment in this way.
For connecing on D+ with high-speed equipment, pull-up resistor at full speed, and low-speed device is then that pull-up resistor connects in D-
On, hub distinguishes low-speed device or full speed and high-speed equipment by judging which root line is raised.USB high-speed equipment
It is identified as full-speed device before this, is then further confirmed that by the data communication of host and equipment between the two, then be switched to
High-speed mode.In high speed mode, it is electric current transmission mode, at this moment the pull-up resistor on D+ can be disconnected.When usb host is examined
After the insertion of measurement equipment, host will issue a series of enumeration requests to equipment, and equipment makes correct response to complete USB device
Enumeration process, to identify specific equipment.
By the on-off connection of control SD or SD card is disconnected using USB similar principle, when selecting SIM card, first
A card or two cards are selected, then select mobile UNICOM or telecommunications to card one or card two in multiple SIM card.
As shown in figure 3, being below the definition of relay pin in figure:
DC+: connection positive pole, for powering to relay；
DC-: connection power cathode；
IN: relay either on or off is controlled by input low and high level；
NO: relay normally open interface；
