Abstract
The invention relates to equipment for priority ranking of subway signal faults. The equipment for the priority ranking of the subway signal faults comprises 512 memorizers, a read-write comparator and an operational amplifier, the 512 memorizers are respectively connected with the input end of the read-write comparator, the output end of the read-write comparator is connected with the input end of the operational amplifier, and the output end of the operational amplifier is connected with peripheral equipment. The invention further provides a method for the priority ranking of the subway signal faults. The equipment and the method for the priority ranking of the subway signal faults enable fault handling of subways to be faster and more reliable, efficiency and accuracy of emergency processing of emergencies in the subways are improved, and service quality of the subways is guaranteed.
Description
Technical field
The present invention relates to a kind of prioritization Apparatus and method for for the subway signal fault.
Background technology
The quality of subway operation quality directly affects social stability, economic development, and the research of this respect is all quite paid attention in countries in the world.
Existing subway signal fault processing system owing to lack effective prioritization equipment, so that the fault handling efficient of signal is low, speed is slow, has affected the quality of subway operation greatly.
Summary of the invention
The object of the invention is to overcome the defective of prior art and a kind of prioritization Apparatus and method for for the subway signal fault is provided, so that signal is processed more fast and reliable.
The object of the present invention is achieved like this:
A kind of prioritization equipment for the subway signal fault of the present invention comprises 512 storeies, read-write comparer and operational amplifier, wherein,
Described 512 storeies link to each other with the input end of described read-write comparer respectively;
The output terminal of described read-write comparer links to each other with the input end of described operational amplifier;
The output terminal of described operational amplifier links to each other with external unit.
The present invention also provides a kind of prioritization method for the subway signal fault, may further comprise the steps:
The storage failure number is come according to the severity level of malfunction in the address of S1:512 storer in order from 0 to 511, and wherein the most serious is 511, and signal 1 expression has this type of fault, and signal 0 expression does not have fault;
S2: the fault number of storing in read-write comparer collection 512 storeies, identify the storer with catastrophic failure code, and the data communication device of this storer crossed operational amplifier output;
S3: after fault handling is complete, the malfunction zero clearing in the respective memory;
S4: repeat above-mentioned steps S1 to S3, until all malfunctions are 0, system enters normal operation.
The present invention is used for the prioritization Apparatus and method for of subway signal fault, so that subway fault handling fast and reliable has more improved efficient and the accuracy of subway to the emergency processing of accident, has guaranteed subway operation quality.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, there is shown the prioritization equipment that the present invention is used for the subway signal fault, comprise 512 storer S, read-write comparer G and operational amplifier A, wherein,
512 storer S link to each other with the input end of read-write comparer G respectively;
The output terminal of read-write comparer G links to each other with the input end of operational amplifier A;
The output terminal of operational amplifier A links to each other with fault handling equipment.
The present invention is used for the prioritization method of subway signal fault, may further comprise the steps:
The storage failure number is come according to the severity level of malfunction in the address of S1:512 storer S in order from 0 to 511, and wherein the most serious is 511, and signal 1 expression has this type of fault, and signal 0 expression does not have fault;
S2: read-write comparer G gathers the fault number of storing among 512 storer S, identifies the storer S with catastrophic failure code, and the data communication device of this storer S is crossed operational amplifier A output;
S3: after fault handling is complete, the malfunction zero clearing among the respective memory S;
S4: repeat above-mentioned steps S1 to S3, until all malfunctions are 0, system enters normal operation.
Above embodiment is only for explanation the present invention's, but not limitation of the present invention, person skilled in the relevant technique, in the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
