For achieving the above object, the hardware implement device of a kind of active and standby working method of the utility model, at least comprise the active and standby each other working method of a motherboard, two and be the veneer that symmetric form is arranged at this motherboard mutually, all be connected between veneer and motherboard, it is characterized in that with connector:
The male connector of this connector is long and short needle construction, and connection pin wherein is a time minute hand for minute hand, the connection pin of power supply, and the connection pin of signal is a hour hand;
In addition, pass a pair of handshake line mutually between two veneers of active and standby working method each other, every handshake line draws in this plate, with the end ground connection that plate is linked to each other;
Secondly, in veneer and connector that motherboard links to each other, select four holding wires of four jiaos for use, four of this four holding wire correspondences connect pins and are hour hand, and these four pins draw equal ground connection in motherboard on all in veneer.
Because the enforcement of above technical scheme, whether the utility model can be realized the charged plug of veneer and discern veneer on the throne, comprise that this plate of identification is on the throne and identification is on the throne to plate, solved the application scenario that the stability of a system is being had relatively high expectations, realize the key component of masterslave switchover working method hardware circuit logic, masterslave switchover can be realized automatically by hardware, switching time is ns (nanosecond) level, realize switching time ms (microsecond) level switch than software control in the prior art, improved 103 times, can be widely used in the system design of similar high-end communication products.
Below in conjunction with drawings and the specific embodiments the utility model is further described in more detail.
Fig. 1 discerns circuit embodiments figure on the throne for the utility model two veneers by mutual biography handshake.
The hardware implement device of a kind of active and standby working method of the utility model is made up of two veneers and a motherboard of active and standby working method each other, all is connected with connector between veneer and motherboard.Be to realize the working method of single board main/standby, the function that veneer must the tenaculum electric mortiser be dialled, for realizing active and standby switching, whether veneer also must can be discerned on the throne, comprise discern this plate whether on the throne with discern whether on the throne to plate.
For realizing the warm swap of veneer, on the connector between veneer and the motherboard, select the male connector of belt length pin and hour hand type for use, wherein, the connection pin on ground is selected minute hand for use, and the connection pin of power supply is selected time minute hand for use, and the connection pin of signal is selected hour hand for use.Like this, when inserting veneer, veneer and motherboard are connected at first be pin, secondly be power pin, be signal pin at last.Because it is very slow that the people inserts the speed of veneer by hand, with respect to the power-on time of veneer, the signal input that then can make device is after the stable output of power module.The chip that the chip of interface selects for use the tenaculum electric mortiser to dial again then can be realized the charged plug of veneer.
Veneer will be realized active and standby working method, and whether must can discern veneer on the throne, comprises that this plate of identification is on the throne and identification is on the throne to plate.Fast automatic switching during for the realization fault, whether veneer should be able to be discerned plate on the throne, is mainboard as this plate present condition, when breaking down,, then should switch and be slave board as normal to plate this moment, former slave board is checked through former mainboard and switches to behind the slave board, then oneself is switched to be mainboard.Since adopt the connector of long and short hands, may be owing to plate, after the minute hand of veneer and motherboard connects, on hour hand does not also connect, as this moment veneer just output start working, will inevitably the business of system be impacted, whether oneself on the throne so veneer also should be able to be discerned at this moment.
Whether on the throne for realizing identification to plate, adopt the veneer of active and standby working method to pass a pair of handshake each other mutually, an end of every handshake draws in this plate, with the end ground connection that plate is linked to each other.During identification, being low as this signal, then representing plate on the thronely, as is high, then represents plate is offed normal.Specific implementation sees also shown in Figure 1.Veneer 1 and veneer 2 be each other to plate, and the number of delivering a letter 1 ground connection in veneer 1 by drawing on the resistance, is transferred to as veneer 1 in veneer 2 mutually, and then veneer 2 is checked through the number of delivering a letter mutually 1 for high, represents that then veneer 1 offs normal, and this be the on the throne implementation methods of veneer 2 inspections to plate.Veneer 1 is checked plate veneer 2 whether on the throne is adopted same implementation method, uses the number of delivering a letter 2 mutually.
Whether on the throne for realizing this plate of identification, four the shortest pins of four jiaos that use veneer to link to each other with motherboard are realized.Four the shortest signal pins of four jiaos of connector equal ground connection in motherboard is drawn on all in veneer.Then during normal working of single board, four all is low level at the signal of answering, do not plug as the arbitrary angle of veneer, then high level can appear in this signal pin of inserting good angle correspondence, and this moment, veneer normally powered on, can with the signal at four angles mutually or, as be low, represent that then veneer is on the throne, as be high, represent that then veneer offs normal.
