Referring to fig. 2, an embodiment of the present invention provides a vehicle alarm method, including:
step S100, dynamically collecting signal items of a vehicle;
the execution subject of this embodiment is an enterprise alarm platform. The whole vehicle CAN (Controller Area Network) bus collects original messages of the vehicle, the original messages are uploaded to the enterprise data monitoring platform in real time by the vehicle-mounted terminal, the enterprise data monitoring platform analyzes the messages in real time according to the communication matrix to obtain custom data and national standard specified data which CAN be used by the enterprise alarm platform, the custom data and the national standard specified data are collectively called as signal items, the signal items comprise vehicle speed, vehicle position, battery voltage, battery current, battery temperature and the like, and the enterprise data monitoring platform dynamically collects the signal items obtained by analyzing the messages.
Dynamic acquisition refers to the process of automatically acquiring information from analog and digital units under test, such as sensors and other devices under test. It is easy to understand that, because the original message of the vehicle is changed in real time and uploaded in real time, and the data monitoring platform also analyzes the message in real time, the dynamic collection of the enterprise alarm platform is also performed automatically and in real time, and all signal items are collected each time.
Step S200, judging whether the signal item has an adaptive target fault judgment rule in a preset fault judgment rule set;
the enterprise alarm platform tests, counts, analyzes and the like on items, values, historical data and the like of signal items, preset corresponding enterprise fault judgment rules for different vehicles and different fault problems, preset national standard fault judgment rules according to national standard alarm requirements, and the fault judgment rule set comprises the enterprise fault judgment rules and the national standard fault judgment rules. The failure determination rule is a determination rule set for information such as one or more items of a signal item and a threshold value for determining a failure problem. When one or more fault determination rules are satisfied by the current signal item, the one or more fault determination rules are all target fault determination rules, namely one or more adapted target fault determination rules exist in a preset fault determination rule set; when the fault determination rule is not satisfied by the current signal item, the fault determination rule is not a target fault determination rule, and if all fault determination rules in the preset fault determination rule set are not target fault determination rules, no adaptive target fault determination rule exists in the preset fault determination rule set.
Preferably, step S400 includes:
acquiring a first fault judgment rule from a fault judgment rule set, and acquiring a signal item and a signal item threshold value of the first fault judgment rule;
judging whether the corresponding dynamically collected signal item exceeds the signal item threshold value according to the signal item;
when dynamically collected signal items corresponding to all signal item items in a first fault judging rule exceed a preset threshold, judging that the first fault judging rule is an adaptive target fault judging rule, and judging whether the signal item has the adaptive target fault judging rule in a preset fault judging rule set.
The first failure determination rule is any failure determination rule in the failure determination rule set, and it is easy to understand that to determine whether the signal item has an adapted target failure determination rule in the preset failure determination rule set, each failure determination rule in the failure determination rule set is to be determined.
The signal item threshold is a preset minimum value and/or maximum value of the signal item.
And acquiring one or more corresponding dynamically acquired signal items according to one or more signal item items of the first fault judgment rule, respectively matching the dynamically acquired signal items with signal item thresholds in the first fault judgment rule, judging whether all the dynamically acquired one or more signal items corresponding to the one or more signal item items of the first fault judgment rule exceed the signal item thresholds specified in the fault judgment rule, judging that the first fault judgment rule is an adaptive target fault judgment rule only when all the dynamically acquired one or more signal item items exceed the signal item thresholds specified in the fault judgment rule, and judging that the signal item has the adaptive target fault judgment rule in a preset fault judgment rule set.
When no or only part of dynamically collected signal items corresponding to the signal item items in the first fault judging rules exceed a preset threshold, judging that the first fault judging rules are not adaptive target fault judging rules, and when each fault judging rule in the fault judging set is not adaptive target fault judging rules, judging that the signal item does not have adaptive target fault judging rules in the preset fault judging rule set.
In this embodiment, the fault determination rule is set by setting a threshold value for the signal item, so that the method is simple and effective, easy to implement, and the numerical form can intuitively embody the severity of the fault, and if abnormal alarm, false alarm and other conditions occur, the problem can be easily found out and solved.
Step S300, if an adaptive target fault judging rule exists, judging whether the target fault judging rule belongs to an automatic auditing type or not;
and if the adaptive target fault judging rule does not exist, ending the vehicle alarm. And continuously judging whether the signal item of the next dynamic acquisition vehicle has an adaptive target fault judgment rule in the preset fault judgment rule set.
After the fault determination rule is formulated, the enterprise classifies the fault determination rule into an automatic auditing type and a manual auditing type according to the fault determination rule and the fault problem corresponding to the fault determination rule, and specifically how to classify the fault determination rule is set by the enterprise, the fault determination rule can be randomly classified only by personal will, the fault determination rule can be automatically classified according to a certain rule, and the fault determination rule and the manual auditing type can be combined to classify the fault determination rule, so that the embodiment is not limited. For example: the fault judgment rules corresponding to national standard alarms, fault judgment rules corresponding to serious fault problems in enterprise alarms, fault judgment rules with higher accuracy and the like can be set as automatic auditing types, and the fault judgment rules corresponding to slight fault problems in enterprise alarms, fault judgment rules with lower accuracy, test types or fault judgment rules in perfect modification and the like can be set as manual auditing types.
In the fault determination process, only the target fault determination rule needs to be determined to be of an automatic audit type or a manual audit type.
Step S400, if the automatic auditing type is adopted, generating a fault alarm of a fault problem pointed by a target fault judging rule;
the fault alarm is an alarm message used for prompting a user, an enterprise or other recourseable unit that the vehicle has a fault problem, and the alarm message can be a short message, a telephone, voice, a vehicle-mounted terminal prompt message, a sound or light prompt of the vehicle and the like.
Preferably, step S400 includes:
if the fault problem belongs to the automatic auditing type, the fault problem pointed by the target fault judging rule is pushed to the after-sales platform and the user equipment in a fault alarm mode.
The mode of pushing to the user equipment can be that a short message, network information and call are sent to the contact mode reserved for the user, or a message is pushed to the vehicle-mounted terminal of the user vehicle, or warning sound or warning light and the like can be sent out by controlling the vehicle through the vehicle-mounted terminal.
After the fault problem is pushed to the after-sales platform and the user equipment in the form of fault alarm, the situation can be timely known by enterprises and users after the fault problem of the vehicle is guaranteed, the fault problem can be timely processed, and the problems that the enterprises are unaware and cannot keep up after sales when the vehicle is in accident are solved.
And S500, pushing the fault problem pointed by the target fault judgment rule to a manual auditing program if the fault problem does not belong to the automatic auditing type.
If the target fault judgment rule does not belong to the automatic auditing type, the target fault judgment rule belongs to the manual auditing type, and the target fault judgment rule needs manual auditing due to reasons such as accuracy, imperfect, needing modification and the like, a manual auditing program is distributed to related technicians, and the related technicians conduct manual auditing on the target fault judgment rule to judge whether to generate a fault alarm or not, and after the manual auditing is finished, the fault alarm can be directly generated or a processing result can be returned to an enterprise alarm platform for processing.
Preferably, after step S500, the method further includes:
acquiring a manual auditing result returned by a manual auditing program according to the fault problem, wherein the manual auditing result comprises sending a fault alarm and not sending the fault alarm;
when a manual auditing result for sending the fault alarm is obtained, the fault problem corresponding to the manual auditing result is pushed to the after-sales platform and the user equipment in the form of the fault alarm.
And when a manual auditing result of not sending the fault alarm is obtained, ending the vehicle alarm.
The manual auditing result is an auditing result generated by a technician after the manual auditing determines whether to send out a fault alarm, and comprises evaluation, suggestion and the like of the manual auditing by the technician, for example: whether the failure determination rule is accurate, the modification suggestion of the failure determination rule, and the like.
The fault problems are returned to the enterprise alarm platform for processing, so that unified management, storage, analysis and improvement of the fault judgment rules and the fault problems are facilitated, the fault judgment rules are continuously perfected and optimized, and the alarm is more accurate and comprehensive.
