Abstract
The utility model discloses a bi-module redundant heat standby measurement and control device, which comprises a monitoring module, wherein the monitoring module is characterized in that the monitoring module is connected with a minimum system respectively through measurement and control interfaces and further directly connected with a measured and controlled device and the minimum system. The bi-module redundant heat standby measurement and control device is mainly used in severe environments.
Description
Technical field
The utility model relates to a kind of measure and control device, relates in particular to a kind of measure and control device that can carry out the duplication redundancy Hot Spare.
Background technology
At present, known measure and control device generally comprises that by a cover hardware minimum system, observing and controlling interface and software kit form.Than under the condition of severe, because the influence of each side such as temperature, humidity, electromagnetic interference (EMI), the situation that program run makes mistakes or crashes might appear in measure and control device at working environment.In case self breaks down measure and control device, total system may be collapsed.
Summary of the invention
In order to overcome existing measure and control device insecure defective of under rugged surroundings, working; The purpose of the utility model is to provide a kind of duplication redundancy Hot Spare measure and control device, and this duplication redundancy Hot Spare measure and control device is added monitoring module and formed by the same configured hardware of two covers, software.When wherein a cover device of working broke down, monitoring module can monitor malfunction immediately, and activates another set of back-up device, makes it can take over work immediately.
The technical solution of the utility model is: a kind of duplication redundancy Hot Spare measure and control device; Comprise monitoring module; It is characterized in that: described monitoring module links to each other with minimum system through the observing and controlling interface respectively, and monitoring module also with by observing and controlling device and minimum system directly links to each other.
The beneficial effect of the utility model is: duplication redundancy Hot Spare measure and control device is added monitoring module and is formed by the same configured hardware of two covers, software; When wherein a cover device of working breaks down; Monitoring module can arrive malfunction by at-once monitor; And activate another set of back-up device, make it can take over work immediately, thereby greatly improved the reliability of measure and control device.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are done further explain.
Referring to accompanying drawing, the utility model comprises that monitoring module is characterized in that: described monitoring module links to each other with minimum system through the observing and controlling interface respectively, and monitoring module also with by observing and controlling device and minimum system directly links to each other.
Two minimum system cycle self checks of the utility model are if self check is normally then sent heartbeat signal by fixed frequency to monitoring module.Whether monitoring module is monitored minimum system according to heartbeat signal in proper working order, and with this allow or the observing and controlling forbidding being attached thereto by the output function of mouth, guarantee that synchronization only allows an observing and controlling interface to by observing and controlling device output signal.Monitoring module also will be exported to two observing and controlling interfaces from the input signal of tested control device simultaneously, finally make two minimum systems have identical input data, guarantee that two minimum systems can carry out identical data and handle operation.Two minimum systems are initialized to different priorities, and one of them is a high priority, and another one is a low priority.Two minimum system heartbeat signals all just often, monitoring module can make the observing and controlling interface that links to each other with the high priority minimum system to by observing and controlling device output signal.When the unusual and low priority minimum system heartbeat signal of high priority minimum system heartbeat signal just often; Monitoring module hardware reset high priority minimum system; Then the priority of two minimum systems is reversed; Low priority minimum system before being about to promotes and is the high priority minimum system, and high priority minimum system is before then reduced to the low priority minimum system, and the observing and controlling interface that enables at last to link to each other with the high priority minimum system is to being exported signal by the observing and controlling device.
Claims (1)
1. a duplication redundancy Hot Spare measure and control device comprises monitoring module, and it is characterized in that: described monitoring module links to each other with minimum system through the observing and controlling interface respectively, and monitoring module also with by observing and controlling device and minimum system directly links to each other.
