Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of specific examples, which are illustrative of the present invention and are not limited to the following embodiments.
The invention provides a device for mixing and editing hard disk control signals by a controller, which comprises: the hard disk back plate is provided with at least one group of connecting slot positions for connecting the controller, and each group of connecting slot positions comprise a hard disk slot position for connecting a hard disk connector and an ID identification slot position for identifying the group of connecting slot positions; the controller is provided with a connecting pin which is matched with the connecting slot position on the hard disk backboard, and the connecting pin comprises a hard disk pin matched with the hard disk slot position and an ID identification pin matched with the ID identification slot position.

As shown in fig. 2, the present embodiment further describes the present solution by taking a dual controller as an example.
Two groups of connecting slot positions are arranged on the hard disk back plate 3, wherein one group of connecting slot positions are arranged on the upper side of the hard disk back plate 3, and the other group of connecting slot positions are arranged on the lower side of the hard disk back plate 3. And each group of the connecting slot positions is provided with an ID identifying slot position, wherein the ID identifying slot position of the connecting slot position on the upper side of the hard disk backboard 3 is pulled down to the ground, and the ID identifying slot position of the connecting slot position on the lower side of the hard disk backboard 3 is pulled up to the power supply, so that the controller can determine the connecting slot position according to the level of the ID identifying slot position.

Correspondingly, the connecting slot positions on the upper side of the hard disk backboard 3 comprise 4 upper hard disk slot positions, and the 4 upper hard disk slot positions are sequentially arranged on the hard disk backboard 3 from left to right; the connecting slot position of the lower side of the hard disk back plate 3 comprises 4 lower side hard disk slot positions, and the 4 lower side hard disk slot positions are sequentially arranged on the hard disk back plate 3 from left to right.
Meanwhile, in order to simplify Layout wiring as much as possible and reduce the number of layers of the PCB, 4 upper hard disk slots are sequentially connected with 4 hard disk connectors one by one, and 4 lower hard disk slots are sequentially connected with 4 hard disk connectors one by one. Because each signal circuit does not intersect, only one layer of PCB board is used.
Two controllers are correspondingly arranged, namely a first controller 1 and a second controller 2, wherein the first controller 1 and the second controller 2 are two identical controllers and can simultaneously control the same hard disk. The management chips of the first controller 1 and the second controller 2 are respectively burned with a first set of indication codes and a second set of indication codes.
