Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of cold backup double-machine switching circuit, comprise host machine part and with the corresponding standby host part of its circuit structure, described host machine part comprises main frame power supply circuits, host switch relay and the conversion of main frame secondary power supply that links to each other successively, the output of main frame secondary power supply conversion is stung the input that adds standby host electricity circuit with input, the dog of host CPU controller respectively and is connected, the output of host CPU controller connects closes standby host electricity circuit, be connected with the cold and hot startup status signal circuit of main frame two-way signaling simultaneously, the output of closing standby host electricity circuit connects main frame remote measurement switching circuit.
Described standby host partly comprises standby host power supply circuits, standby host switch relay and the conversion of standby host secondary power supply that links to each other successively, the output of standby host secondary power supply conversion is stung the input that adds main frame electricity circuit with input, the dog of standby host cpu controller respectively and is connected, the output of standby host cpu controller connects closes main frame electricity circuit, be connected with the cold and hot startup status signal circuit of standby host two-way signaling simultaneously, the output of closing main frame electricity circuit connects standby host remote measurement switching circuit.
Described main frame, standby host switch relay connect direct instruction respectively, direct instruction is main-open-sub-close instruction and sub-open-main-close instruction, directly control primary power source with switch relay, controlled primary power source is given system's power supply of main frame, standby host respectively after the secondary power supply conversion.Dog stings the output that adds standby host electricity circuit, the output of closing standby host electricity circuit connects the standby host switch relay; Dog stings the output that adds main frame electricity circuit, the output of closing main frame electricity circuit connects the host switch relay.
The cold and hot startup status signal circuit of main frame or standby host is a D flip-flop, and this state is 0 during cold start-up, and the software watchdog counter in the corresponding cpu controller puts 0; Take place to make that this state is 1 when the house dog dog stings incident, warm start does not change this state.Corresponding cpu controller was inquired about this state after main frame or standby host resetted at every turn, if 1, corresponding counting variable adds 1.
When switching, system work process such as Fig. 2, shown in Figure 3.
As shown in Figure 2, taken place when main frame has electricity after the 1st house dog dog sting incident, oneself resets main frame, powers up to standby host simultaneously.Move to state 2 by state 1, two-shipper all is in the back init state that resets, and system has entered reconstituted state.After the host reset, carry out initialization again, wait for 4 seconds after the initialization normal termination, send a command software then and close standby host.After this moment, standby host powered up, the stand-by period after the initialization normal termination was 8 seconds, sent a command software then and closed the main frame electricity, moved to state 1 by state 2.
As shown in Figure 3, the back does not recover normal if main frame resets for the 1st time, the 2nd house dog dog taken place sting incident, at this moment after the host reset, priority reduces, and the stand-by period is extended for 16 seconds after the initialization normal termination, and after the standby host initialization normal termination stand-by period still be 8 seconds, therefore standby host can turn-off host power supply, moves to state 3 by state 2.
Judge whether to take place dog according to cold and hot startup status signal circuit and sting, the software collection dog stings count value.Simultaneously can return ground by remote measurement.After if hot reset takes place repeatedly, ground control system can be carried out direct instruction and switch by the judgement of remote measurement value.
Circuit of the present invention realizes on product, and through product test, Overall Power Consumption is 6.86W under the cold standby mode of operation, reduced 1.34W (certain Star Service central computer product actual measurement power consumption is: 8.2W) than original.The cold and hot startup sign that is provided with in the product can normally be visited by processor, further combined with the processing of application software, can realize the switchover policy of envisioning.
