Description
Technical field
The utility model relates to field of computer peripherals, specifically a kind of PS/2 interface keyboard and mouse batch detection equipment.
Background technology
PS/2 interface keyboard and mouse have obtained using widely as the standard configuration of computing machine.The debugging of PS/2 interface keyboard and mouse in the past mainly depends on the PS/2 interface of computing machine, that is to say that common computed PS/2 interface detects keyboard and mouse.And in the batch process of PS/2 interfacing equipment detected, there was following shortcoming in this method:
(1) PC only has 2 road PS/2 interfaces, can't detect the PS/2 interfacing equipment more than 3 or 3 simultaneously;
(2) when detecting the PS/2 interfacing equipment, if warm swap is subjected to measurement equipment to damage PS/2 interfacing equipment and PC easily.Starting continually in testing process simultaneously and shut down computer can the reduction detection efficiency.
This shows that the traditional PS/2 interfacing equipment detection methods not only very low batch detection that can not adapt to of efficient require also to exist certain potential safety hazard.
Summary of the invention
The purpose of this utility model is a kind of PS/2 interface keyboard mouse batch detection equipment of development, and PC and the tested PS/2 keyboard and mouse of many covers are linked together, and detects many PS/2 equipment simultaneously to reach the purpose that improves detection efficiency by PC.It is brake that this checkout equipment provides promptly inserting of PS/2 interface, realizes that charged plug detects.This checkout equipment is supported current protecting function simultaneously, and the short circuit of tested device power supply (DPS) fault can be cut off the electricity supply and be supplied with the protection PC and be subjected to measurement equipment.
The utility model PS/2 interface keyboard and mouse batch detection equipment comprise: protocol conversion module circuit and USB HUB modular circuit are housed in the cabinet, and two modular circuits connect with lead.
Protocol conversion module is a polylith, and a protocol conversion module circuit has two PS/2 interfaces, a USB interface.
USB HUB modular circuit has the interface that is connected with protocol conversion module, the interface that is connected with PC.
The protocol conversion module circuit comprises: protocol conversion module is made up of 1 usb microcontroller, 2 PS/2 interface sockets, 1 USB socket and peripheral circuit.
USB HUB modular circuit comprises: USB HUB module is made up of 1 USB HUB controller chip, 5 USB socket, power light and peripheral circuits.
PS/2 interface keyboard mouse batch detection equipment is realized the acquisition process to keyboard and mouse PS/2 protocol data, is converted into HID kind equipment data and sends PC to by USB interface.After the HID kind equipment driver of PC Windows operating system receives HID kind equipment data, it is passed to the detection that application program realizes PS/2 equipment.
PS/2 interface keyboard mouse checkout equipment shown in Figure 1 can be realized the data-switching of 8 road PS/2 interface data signals to 1 road usb bus HID protocol data signal.The PS/2 protocol data that the input of PS/2 keyboard and mouse produces becomes HID protocol data signal by PS/2 interface keyboard and mouse batch detection device translates.
PS/2 interface keyboard and mouse batch detection equipment mainly are made up of two parts:
(1) protocol conversion module
Protocol conversion module is finished the protocol conversion between 2 road PS/2 interface protocols and 1 road usb bus interface.This 2 road PS/2 interface can connect keyboard or mouse arbitrarily, and the USB interface of protocol conversion module adopts USB 1.1 bus low-speed interfaces to link to each other with main frame.Protocol conversion module can detect automatically to keyboard or the mouse that is connected, when protocol conversion module has detected keyboard or mouse connection, protocol module will distinguish automatically that what connect on the corresponding interface is keyboard equipment or mouse device, by corresponding keyboard processor and mouse processor the semanteme of agreement be sent to master processor program.Master routine becomes HID class data layout with the data-switching of keyboard or mouse, hands over the usb communication device to send to main frame, and vice versa.
Protocol conversion module is supported the hot-swappable of PS/2 interface and promptly inserted is brake, supports 33 key idler wheel mouses and MultiMedia Keyboard, and the plug-and-play feature of support USB interface.Because the driver of the existing HID of Windows 98 and above version thereof, the PC that therefore above version of window is installed need not to be the protocol conversion module install driver.Protocol conversion module is powered by usb bus, need not other power supply.
(2) USB HUB module
USB HUB module in the checkout equipment is the USB 1.1 full speed HUB of 1 road uplink port and 4 road downlink ports.This USB HUB module is communicated by letter with PC by realizing 4 protocol conversion modules and being connected of main frame USB interface 8 road PS/2 interfacing equipments.PC receives the HID protocol data by usb bus, realizes the detection to PS/2 keyboard and mouse.When certain PS/2 interfacing equipment was short-circuited fault, the power supply of checkout equipment was cut off in the usb bus overcurrent protection meeting of PC, thereby plays a protective role.
The advantage of the utility model PS/2 interface keyboard and mouse batch detection equipment is: the realization PC is connected with many PS/2 equipment.PC is subjected to measurement equipment to provide power supply to supply with by usb bus for this PS/2 interface checkout equipment and 8 road PS/2 interfaces, by PS/2 interface checkout equipment 8 road PS/2 interfacing equipments is detected.This equipment is supported i.e. function such as survey and short-circuit protection is discerned, promptly inserted to the automatic type of PS/2 equipment.The PS/2 checkout equipment adopts Embedded design proposal, have volume small and exquisite, in light weight, be easy to carry, easy to use, reliability is high and advantage such as with low cost, only needs a USB cable to detect 8 road PS/2 equipment.In actual detected, PS/2 interface checkout equipment can be brought up to 8/10 seconds, the satisfied detection requirement of PS/2 equipment in batches from 2/minute with the traditional detection time.
