Abstract
Disclosed is a hard disc data reading device which comprises an external USB host; when the high level of the power line in a USB/IDE interface is detected by a power detector; a strobe signal is correspondingly inputted into an electronic switch by the power detector, enabling the electronic switch to select the USB/IDE interface to communicate with an IDE hard disc; meanwhile, the IDE hard disc is enabled to be separated with a host computer; when the USB host connected with the USB/IDE interface is removed, a low level of the power line in the USB/IDE interface is detected; a strobe signal is correspondingly inputted into the electronic switch by the power detector, enabling the electronic switch to select the host computer to connect with the IDE hard disc; meanwhile, the USB/IDE interface is enabled to be disconnected with the IDE hard disc automatically. The hard disc data reading device has the advantages that the hard disc data reading device solves the problems that the IDE hard disc can be only connected with a single device in the prior art and the data of the IDE hard disc can not be updated through an external device conveniently; when the data of the IDE hard disc can be updated by an external device, the cost is reduced; the control and operation become simple and reliable; the work efficiency is improved.
Description
[technical field]
The utility model is about the embedded device field, particularly a kind of hard disk reading of data device.
[background technology]
In the prior art, mainly be that peripheral interface by host computer connects hard disc apparatus, the control of the hard disk that can not automatically switch singlely to the visit of IDE (Integrated Device Electronics Integrated Device Electronics) hard disk.Want to write data to hard disk from the outside, need by the host computer transfer, but not all host computer can interim data, therefore, in some embedded devices, hard disk can only be dismantled, after being connected to other terminal and writing data from embedded device, the hard disk that will write again after the external data disconnects from this terminal, reloads embedded device.The problem that frequent dismounting hard disk renewal data source is brought is to damage hard disk and even embedded device itself easily, and the while can make cost up like this, control is complicated, efficient is low.Be badly in need of a kind of unification, stable, low-cost, solution efficiently.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of unification, stable, low-cost, hard disk reading of data device efficiently.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of hard disk reading of data device, comprise host computer, IDE (Integrated Device Electronics) hard disk, also comprise Power supply detector, electronic switch, and USB/IDE (USB (universal serial bus)/Integrated Device Electronics) interface, wherein the input end of Power supply detector is connected to described USB/IDE interface, output terminal is connected respectively to described host computer and described electronic switch, described host computer and USB/IDE interface are connected on the IDE hard disk by electronic switch, host computer and USB/IDE interface are connected with electronic switch, and electronic switch all is to connect by IDE (Integrated Device Electronics) interface with being connected of IDE hard disk.
During use, at first allow the IDE hard disk from the external usb host reading of data, this step comprises:
At first, circumscribed USB main frame on the USB/IDE interface, secondly, the power lead that Power supply detector detects in this USB/IDE interface is a high level, and then, Power supply detector is imported corresponding gating signal according to this testing result to electronic switch, thereby make described electronic switch select the USB/IDE interface to be connected communication with the IDE hard disk, be usb host control IDE hard disk, make the IDE hard disk be connected disconnection with host computer simultaneously, then the IDE hard disk reads data from this circumscribed USB main frame;
Then, remove the circumscribed USB main frame from the USB/IDE interface, step comprises:
At first, remove the described external usb host on the USB/IDE interface, it is low level that the power supply test section detects USB/IDE interface power lead, then, Power supply detector is imported corresponding gating signal according to this testing result to electronic switch, selects host computer to be connected with the IDE hard disk thereby drive electronic switch, i.e. PC control IDE hard disk, read the data in the IDE hard disk, be connected and the USB/IDE interface is disconnected with the IDE hard disk automatically.
The advantage of the utility model hard disk reading of data device is: solved that the IDE hard disk can only be articulated on the single equipment in the prior art, can not upgrade the problem of hard disc data quickly and easily from the outside, upgrade hard disc data by external unit, make control, operation is simple and reliable, can reduce cost, increase work efficiency.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the hardware connection diagram of the utility model hard disk reading of data device.
Fig. 2 is the operational flowchart of the circumscribed USB main frame of the utility model hard disk reading of data device.
Fig. 3 is the operational flowchart that removes the circumscribed USB main frame of the utility model hard disk reading of data device.
[embodiment]
See also Fig. 1, the hardware connection layout for the utility model hard disk reading of data device mainly consists of the following components: Power supply detector, electronic switch, host computer, and USB/IDE (USB (universal serial bus)/Integrated Device Electronics) interface.
The annexation of various piece is as described below:
The input end of Power supply detector is connected to the USB/IDE interface, and output terminal is connected respectively to host computer and electronic switch, and host computer and USB/IDE interface are connected on IDE (Integrated Device Electronics) hard disk by electronic switch.Being connected of host computer and USB/IDE interface and electronic switch wherein, and electronic switch all is to connect by ide interface with being connected of IDE hard disk.
Wherein the function of Power supply detector is whether real-time detection has external usb host to be connected to the USB/IDE interface, and it is a precondition of judging IDE hard disk selector channel.The function of electronic switch then is to select the real work passage of IDE hard disk according to the signal of the Power supply detector that receives.Host computer and USB/IDE interface are connected on the IDE hard-disk interface by electronic switch, communicate with the IDE hard disk respectively under corresponding triggering condition.
See also Fig. 2 and Fig. 3, be the use process flow diagram of the utility model hard disk reading of data device, wherein Fig. 2 is the operational flowchart of circumscribed USB main frame, its objective is to allow the IDE hard disk from this usb host reading of data, and its operating process is as follows:
At first, circumscribed USB main frame on the USB/IDE interface, then the power lead in USB/IDE interface this moment is a high level, secondly, the power lead that Power supply detector detects in this USB/IDE interface is a high level, then, Power supply detector is imported corresponding gating signal according to this testing result to electronic switch, thereby make electronic switch select the USB/IDE interface to be connected communication with the IDE hard disk, it is usb host control IDE hard disk, make the IDE hard disk be connected disconnection with host computer simultaneously, then the IDE hard disk reads data from this circumscribed USB main frame;
See also Fig. 3, remove the operational flowchart of circumscribed USB main frame, its objective is to allow host computer reading of data from the IDE hard disk, its operating process is as follows:
At first, external usb host is removed from the USB/IDE interface, it is low level that Power supply detector detects USB/IDE interface power lead, then, Power supply detector is imported corresponding gating signal according to this testing result to electronic switch, selects host computer to be connected with the IDE hard disk thereby drive electronic switch, i.e. PC control IDE hard disk, reading of data from the IDE hard disk is connected and the USB/IDE interface is disconnected with the IDE hard disk automatically.In this scheme, the priority ratio host computer height of external usb host control hard disk.
