[embodiment]
As shown in Figure 1, adopting the DVR video monitoring program of the method that the DVR video monitoring system in case of system halt restarts control main frame CPU after operation restarts to deadlock and realizes that circuit continues the transmission recurrent pulses; Whether deadlock is restarted the described recurrent pulses of realization circuit supervision and is stopped; As for not, just continue operation DVR video monitoring program; As for being, just restarting and realize that circuit connects DC power supply with the main frame wire jumper that resets by deadlock; At this moment, main frame and DVR video monitoring program restart.
As shown in Figure 2, the DVR video monitoring system in case of system halt is restarted and is realized that circuit comprises pulse generation unit, signal generating unit and relay circuit.When the pulse generation unit normally moves in DVR video monitoring program, be subjected to the CPU control of main frame to send the recurrent pulses that continue to signal generating unit.When signal generating unit interrupts surpassing the default time at recurrent pulses, just send the computer Restart Signal to relay circuit.Described relay circuit connects with the wire jumper that resets of main frame, under the triggering of Restart Signal, the wire jumper that resets of main frame is connect DC power supply, and main frame and DVR video monitoring program are restarted.
DVR video monitoring system in case of system halt of the present invention is restarted the structure that realizes embodiment of circuit and operation principle such as Fig. 3 to shown in Figure 5.Present embodiment adopts the STC single-chip microcomputer to communicate with main frame via GPIO mouth, the pci bus S of video capture processor, the state of the DVR video monitoring program of supervisory control comuter main frame operation in real time, if deadlock situation, single-chip microcomputer just output signal is controlled a relay to realize that main frame restarts, and starts DVR video monitoring program simultaneously automatically.
The operation principle that the DVR video monitoring system in case of system halt is restarted the realization circuit is as follows: when DVR video monitoring program is normally moved on the main frame, remove the 75th pin (GPIO mouth) of control of video acquisition chip SAA7130 continuously by the PCI general line, promptly the 3rd human hair combing waste to single-chip microcomputer STC12C2052 send recurrent pulses.Single-chip microcomputer STC12C2052 is receiving this pulse always, if video monitoring program deadlock situation, just can not send recurrent pulses to single-chip microcomputer STC12C2052, single-chip microcomputer STC12C2052 does not just judge that as receive recurrent pulses above the time of setting crashing appears in the video monitoring program or main frame crashes.Single-chip microcomputer STC12C2052 sends a high level to the 11st pin (P1.7), makes triode Q3 conducting, and at this moment, the 2nd pin (collector electrode) that the 8th pin (control pin) of relay (AGN2004) connects triode becomes low level, to drive relay.The normally opened contact of relay (the 3rd pin and the 4th pin, the 5th pin and the 6th pin) closure, and this is connected to resetting on the main frame (RST) wire jumper to the contact by lead, makes (RST) wire jumper that resets connect DC power supply, causes main frame to be restarted automatically.
Single-chip microcomputer STC12C2052 interface definition is as follows:
As low 1 of data, the handshake of conduct and PC when restarting judged whether to start T0 when P3.0----encrypted
As low 2 of data, being used to when restarting receive the high level that PC comes when P3.1----encrypts, is timer T0 again
When P3.2----encrypts as the external interrupt input port
When encrypting, P3.3----hangs down 3 as data
When encrypting, P3.4----hangs down 4 as data
P3.5----is used to judge whether the startup deadlock to restart program, and (be 0, program is restarted in startup; Be 1, be in the encryption stage, wait for external interrupt always)
Single-chip microcomputer STC12C2052 interface is as follows with the annexation of the GPIO mouth of video capture processor:
RST----GPIO9 P3.0----GPIO10 P3.1----
GPIO11
P3.2----GPIO15 P3.3----GPIO14 P3.4----
GPIO13
P3.5----GPIO12。
Application action:
The input password finish, successfully enter program after, send out a positive pulse to GPIO12, high level lasting time is about 1ms, behind about 10ms GPIO10 is changed to " 1 " after the transmission positive pulse, to be the square-wave pulse of 10ms to the GPIO11 transmission cycle, duty ratio is 1: 2. afterwards
The method embodiment Single Chip Microcomputer (SCM) program flowchart text that DVR video monitoring system in case of system halt of the present invention is restarted: start DVR video monitoring program, at first trigger the encrypting and authenticating module, if be proved to be successful, the normal DVR video monitoring program that starts, DVR sends a timing pulse signal to single-chip microcomputer always then, and single-chip microcomputer is being monitored this signal always, if in the time of agreement, can not receive this timing signal, and judge not belong to and normally withdraw from DVR video monitoring program, just judge that unexpected the deadlock appears in DVR video monitoring program or main frame this moment, this moment, single-chip microcomputer set P3.7 (STC12C2052 the 11st pin) promptly restarted main frame.
