Accompanying drawing explanation
Fig. 1 is the schematic flow sheet that the embodiment of the present invention manufactures the abnormality eliminating method of equipment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described, it is clear that described embodiment is only that the part of the present invention is real
Execute example rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under not making creative work premise, broadly falls into this
The scope of invention protection.
See Fig. 1, be the schematic flow sheet of the abnormality eliminating method of embodiment of the present invention manufacture equipment.
The abnormality eliminating method of the present embodiment comprises the following steps:
S1: gather the operational data of manufacture equipment.
Wherein, the operational data manufacturing equipment can be the status data of manufacture equipment self, such as
The data such as the voltage of manufacture equipment, electric current, temperature, control parameter, it is also possible to be manufacture equipment institute
The environmental data of place's environment, the such as environmental data such as temperature, humidity, either status data is still
Environmental data, it is necessary to can clearly quantify.The operational data of manufacture equipment can be by sensing
Device gathers.
S2: search the exception matched with operational data in the abnormality mapping table constructed in advance
Types value.
Wherein, each operational data can find the different of correspondence in abnormality mapping table
Often types value, such as operational data are temperature value, and corresponding exception class offset represents temperature anomaly,
Operational data is force value, and corresponding exception class offset represents that temperature anomaly is pressure anomaly.Need
Note all, after only operational data exceeds standard, just can find exception class offset.
In the present embodiment, abnormality mapping table include different types of parameter value and each
The parameter value of class judgment condition one to one and abnormal one to one with each judgment condition
Types value, step S2 specifically includes:
The parameter identical with operational data kind is searched in the abnormality mapping table constructed in advance
Value；
Judge whether operational data meets the judgment condition corresponding with parameter value；
If meeting judgment condition, then search the exception class offset matched with judgment condition.
Specifically, the kind of operational data is if temperature, then in look-up table, kind is temperature
Parameter value, then look up the judgment condition that this parameter value is corresponding, finally whether judge operational data
Meet this judgment condition, if it is satisfied, explanation temperature anomaly, then search corresponding different of judgment condition
Often types value.
S3: obtain the current operating state of manufacture equipment, and redirect logical mappings construct in advance
Table is searched and redirects logical value with exception class offset and current operating state match.
Wherein, the current operating state manufacturing equipment can be stored in special state machine.Each
Plant exception class offset and current operating state can find correspondence in redirecting logical mappings table
Exception class offset.
In the present embodiment, step S3 specifically includes:
Obtain the current operating state of manufacture equipment；
Lookup and exception class offset and work at present shape in logical mappings table is redirected construct in advance
The abnormal kind value of state all correspondences and exception priority value；
What lookup was corresponding with abnormal kind value and exception priority value redirects logical value.
Specifically, in redirecting logical mappings table, the work corresponding to exception class offset is first searched
State, then in the duty found, determine the duty identical with current operating state,
Then look up the abnormal kind value corresponding with duty and exception priority value, finally search with
What abnormal kind value was corresponding with exception priority value redirects logical value.
S4: search and current operating state and redirect logical value redirecting in mapping table of constructing in advance
The target operating condition matched.
Wherein, each current operating state and redirect logical value and can look in redirecting mapping table
Find the target operating condition of correspondence.In the present embodiment, redirect mapping table and include different current
Duty and each current operating state redirect logical value one to one and redirect with each
Logical value target operating condition one to one.Specifically, first search in redirecting mapping table
To redirecting logical value, then look up the target operating condition that current operating state is corresponding.
In the present embodiment, after step s4, also include: target operating condition is set as
The current operating state of manufacture equipment.Specifically, if the current operating state of the equipment of manufacture can
To be stored in special state machine, then the current operating state in state machine can be updated to
Target operating condition.
S5: search the operation matched with target operating condition in the command mappings table constructed in advance
Instruction.
Wherein, each target operating condition can find the behaviour of correspondence in command mappings table
Instruct.In the present embodiment, command mappings table include different target operating condition and with often
One target operating condition operational order one to one.
S6: manufacture equipment is carried out abnormality processing according to operational order.
Below the abnormality eliminating method of the embodiment of the present invention is described in detail by citing.
In this example, as a example by certain plastic part production line, relevant manufacture equipment has three kinds of work
State, two of which is abnormality, and one is normal operating conditions.This production line needs prison
The operational data of control has three kinds, is the operation delay time of PLC, oven temperatures and air pressure respectively
Power.First, structural anomaly state mapping map, redirect logical mappings table, redirect mapping table and instruction
Mapping table, respectively as shown in table 1-table 4.

Table 3 redirects mapping table
Table 4 command mappings table
Assume that currently collecting oven temperatures is 400 degrees Celsius, through look-up table 1, finds different
Often types value is A_0；In state machine, the current operating state manufacturing equipment is Se_0, Jing Guocha
Looking for table 2, finding and redirecting logical value is C01；Through look-up table 3, find target operating condition
For Se_1, now, the current operating state of the equipment of manufacture is set as Se_1 by state machine；Pass through
Look-up table 4, finds operational order corresponding to target operating condition Se_1.Refer to thus according to operation
Order controls manufacture equipment and gives a warning, and suspends every operation until manually recovering.
By the way, the abnormality eliminating method manufacturing equipment of the embodiment of the present invention is by advance
Structural anomaly state mapping map, redirect logical mappings table, redirect mapping table and command mappings table,
After gathering the operational data of product line, it is possible to accurately determine operational order, and then manufacture equipment is entered
Row abnormality processing such that it is able to combine the concrete condition producing line and the abnormal conditions of the equipment of manufacture are carried out
Accurately process.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention,
Every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion, or
Directly or indirectly being used in other relevant technical fields, the patent being the most in like manner included in the present invention is protected
