Described link monitoring module links to each other with wireless network with wired bridge by twisted-pair feeder.Described switch controller is connected with wireless network with wired bridge by power line.Adopt the RS232 serial ports to be connected between described link monitoring module and the switch controller.Described wireless network is CDMA (WCDMA/TDSCDMA/GPRS/PHS) wireless network.Described switch controller is given wired bridge or the power supply of CDMA (WCDMA/TDSCDMA/GPRS/PHS) wireless network.
A kind of data acquisition application process that adopts double standby links is monitored in real time to two outbounds of data harvester, may further comprise the steps:
(1) the link monitoring module is confirmed link working state by sending packet mutually with acquisition terminal;
(2) whether the reception of link monitoring module judgment data bag surpasses preset threshold at interval, as not, judges that then link is working properly, otherwise changes step (3);
(3) if packet accept surpass preset threshold blanking time, the link monitoring module repeats to send packet and sounds out, the number of times that repeats to send packet is less than or equal to 3.
(4), return step (1) if receive packet;
(5) if do not receive packet, the link monitoring module sends switching command to switch controller, carries out link switchover.
(6) the link monitoring module is reported to the police.
Because adopt technique scheme, the present invention has following beneficial effect:
The present invention combines by software and hardware, uses the link backup of wired, wireless double standby links as data acquisition unit, has overcome the fragility of single chain-circuit system in the past.In addition, also to have eliminated two cable network links identical outer thereby cause the harmful effect of network paralysis because of suffering in the present invention.That the present invention adopts is wired, the innovative technology of wireless double standby links, even when cable network breaks down, still can build the link of data acquisition by CDMA (WCDMA/TDSCDMA/GPRS/PHS) wireless network, thereby guarantee the normal operation of data collection service.
Description of drawings
Fig. 1 is a structure chart of the present invention;
Fig. 2 is a workflow diagram of the present invention.
Specific embodiments
As shown in Figure 1, a kind of data acquisition unit that adopts double standby links, communicate by letter with acquisition terminal by two outbounds, described pair of outbound adopts the communication mode of wired bridge and/or wireless network, and this device also comprises link monitoring module and switch controller; Described link monitoring module links to each other with wireless network with wired bridge by twisted-pair feeder; Switch controller is connected with wireless network with wired bridge by power line; Then adopt RS232 serial ports ways of connecting between link monitoring module and the switch controller.
Wired bridge of the present invention mainly be to provide wired transmission link for data acquisition unit.This wire transmission link is as the primary link of data acquisition unit.
Wireless network of the present invention mainly is to provide wireless transmission link for data acquisition unit.This wireless transmission link is as the backup link of data acquisition unit.This wireless network is CDMA (WCDMA/TDSCDMA/GPRS/PHS) wireless network.
The power supply of wired bridge of the present invention and CDMA (WCDMA/TDSCDMA/GPRS/PHS) wireless network is to be provided by the link switchover controller, and switch controller only provides the wherein power supply of an equipment; When wire link broke down, switch controller just cut off the power supply of wired bridge, then provided power supply to CDMA (WCDMA/TDSCDMA/GPRS/PHS) wireless module.Wherein the switching delay time is approximately 30 seconds at the latest.
Link monitoring module of the present invention was monitored the working condition of outbound in 24 hours in real time, promptly detected the connecting path with acquisition terminal.If take place then to send instruction unusually, finish link switchover by switch controller to switch controller.
A kind of data acquisition application process that adopts double standby links is monitored in real time to two outbounds of data harvester, may further comprise the steps:
(1) the link monitoring module is confirmed link working state by sending packet mutually with acquisition terminal;
(2) whether the reception of link monitoring module judgment data bag surpasses preset threshold at interval, as not, judges that then link is working properly, otherwise changes step (3);
(3) if packet accept surpass preset threshold blanking time, the link monitoring module repeats to send packet and sounds out, the number of times that repeats to send packet is less than or equal to 3.
(4), return step (1) if receive packet;
(5) if do not receive packet, the link monitoring module sends switching command to switch controller, carries out link switchover.
(6) the link monitoring module is reported to the police.
Embodiment 1
Tentation data acquisition applications system outlet primary link (wire link) breaks down, then link switchover flow process as shown in Figure 2, concrete steps are:
Step 201: regularly send mutually between link monitoring module and the acquisition terminal " link detecting packet "/receive " link detecting response data packet ".
Step 202: the link monitoring module judges whether the reception of " link detecting packet " surpasses preset threshold at interval, if do not surpass threshold value, then link is working properly; If surpass threshold value then think that there be " incipient fault " in link.
Step 203: the link monitoring module sends " link detecting packet " and carries out repeatability exploration, maximum 3 times.
Step 204: the link monitoring module judges whether receive " link detecting response data packet " (promptly judging whether to receive " link detecting response data packet " in the time at prescribed threshold) in repeatability is soundd out in souning out each time.If receive, judge that then link is working properly; If do not receive, then judge link failure.
Step 205: the link monitoring module sends switching command to the link switchover controller by the RS232 serial ports, carries out link switchover.
Step 206: the link monitoring module is reported to the police to the system manager by modes such as notes simultaneously.
The present invention adopts the collaborative switching of finishing link of software and hardware, and software is mainly used in the working condition of real time monitoring outbound, in case note abnormalities, just starting hardware at once automatically switches to reserve link.
