Description

Technical Field

[0001] The present invention relates to the technical field of vehicle fault information management, and in particular to a vehicle fault information management system based on a cloud platform. Background Art

[0002] The vehicle fault management system is a system used to diagnose, record and manage vehicle fault information. It usually consists of hardware and software, and is designed to help car owners and maintenance technicians handle and solve vehicle faults more effectively. The role of the vehicle fault management system is that the system can identify and record the vehicle's fault codes, warning information and sensor data. By connecting to the vehicle's diagnostic interface, the system can monitor various parameters of the vehicle in real time to assist in quickly and accurately diagnosing faults;

[0003] Brake failure and engine failure in vehicle failure have a great impact on the vehicle. They are directly related to the safety and normal operation of the vehicle. Brake failure will affect the braking performance of the vehicle and have a serious impact on vehicle safety. The engine is the power source of the vehicle. Engine failure will directly affect the performance and driving safety of the vehicle. Relevant data needs to be collected during the driving process of the vehicle. For this purpose, the automobile fault information management system is needed to collect and save this data. The automobile fault information management system can record and store vehicle fault information, including fault codes, sensor data, and system status, so that car owners and maintenance personnel can quickly grasp the faults that have occurred in the vehicle;

[0004] At present, after the automobile fault management system collects vehicle fault information, it usually displays the vehicle fault code to the maintenance personnel or the driver. However, drivers who have not received professional training cannot recognize the fault code and need to query to know what kind of fault the vehicle has. When these faults occur during driving, the driver cannot quickly feedback the fault problem to the maintenance personnel, which increases the time for vehicle maintenance and rescue. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the present invention provides a car fault information management system based on a cloud platform, which has the function of feeding back vehicle fault information to maintenance personnel or drivers through a fault output unit via its display screen. By directly feeding back relevant abnormal values ​​to the driver, the driver can intuitively understand the vehicle-related fault problems based on the abnormal values, and the driver can give feedback to the maintenance personnel based on the relevant fault problems they have mastered. The maintenance personnel can prepare corresponding maintenance materials based on the fault information provided by the driver, and can assist the maintenance personnel in quickly repairing the faulty vehicle during the rescue process, thereby shortening the time for vehicle repair and rescue, etc., thereby solving the above-mentioned problems.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A vehicle fault information management system based on a cloud platform, comprising a vehicle data acquisition module, a vehicle data analysis module, a cloud server and a fault output unit;

[0009] The vehicle data acquisition module also includes an engine pulse sensor unit, a brake temperature sensor unit, and a collision sensor unit, wherein the engine pulse sensor unit is used to collect the real-time pulse value MC of the engine, the brake temperature sensor unit is used to collect the real-time temperature value WD around the vehicle brake, and the collision sensor unit is used to collect the voltage value Dy output after the collision. The vehicle data acquisition module sends the collected data to the vehicle data analysis module through the network;

[0010] The vehicle data analysis module is used to analyze the collected data according to different algorithms. The vehicle data analysis module calculates the vehicle engine speed value Zs, the brake temperature value Zwd and the collision force value Pz respectively. The vehicle data analysis module is provided with a vehicle engine speed threshold value ZSyz, a brake temperature threshold value ZDyz and a collision force threshold value Pzyz. The vehicle data analysis module compares the calculated vehicle engine speed value Zs, the brake temperature value Zwd and the collision force value Pz with the vehicle engine speed threshold value ZSyz, the brake temperature threshold value ZDyz and the collision force threshold value Pzyz, and sends the vehicle engine speed value Zs, the brake temperature value Zwd and the collision force value Pz and the comparison result to the cloud server through the network;

[0011] The cloud server stores the comparison result in its storage medium. The cloud server is connected to a fault output unit network. The fault output unit is used to output the fault location of the vehicle.

[0012] Preferably, the algorithm formula for calculating the automobile engine speed value Zs is as follows:

[0013] Zs=60*MC*zq

[0014] In the formula, 60 means there are 60 seconds in a minute, zq represents the engine operating cycle, which is the time required for an engine to complete a working cycle in the ignition sequence of each cylinder. Substituting the number of pulses per minute and the engine operating cycle into the formula, the car engine speed value Z can be calculated.

[0015] Preferably, the brake temperature value Zwd algorithm formula is as follows:

[0016] Zwd=dy*xs*WD

[0017] In the formula, xs represents the temperature coefficient, and its value is determined by the manufacturer and model of the brake. dy is the voltage signal generated when the brake is applied. dy*xs*WD represents the value obtained by combining the collected temperature values.

[0018] Preferably, the collision force value Pz algorithm formula is as follows:

[0019]

[0020] In the formula, mg is the sensitivity of the collision sensor unit, which is used to reflect the sensor's ability to sense input signals. This value is a fixed value. The collision force value when a collision occurs is obtained by dividing the output voltage by the sensitivity.

[0021] Preferably, the vehicle data analysis module sends the calculated automobile engine speed value Zs, brake temperature value Zwd and collision force value Pz to the cloud server via the network.

[0022] Preferably, the automobile engine speed threshold value ZSyz ranges from 5000 to 7000;

[0023] The brake temperature threshold ZDyz has a value range of 200°C to 300°C;

[0024] The collision force threshold value Pzyz ranges from 5g to 10g.

[0025] Preferably, the vehicle data analysis module compares the calculated vehicle engine speed value Zs with the vehicle engine speed threshold ZSyz. When the vehicle engine speed value Zs is greater than the vehicle engine speed threshold ZSyz, it is determined that the engine is abnormal, and the engine fault information is sent to the cloud server;

[0026] The vehicle data analysis module compares the calculated brake temperature value Zwd with the brake temperature threshold ZDyz. When the brake temperature value Zwd is greater than the brake temperature threshold ZDyz, it is determined that the brake is abnormal and the brake fault information is sent to the cloud server.

[0027] The vehicle data analysis module compares the calculated collision force value Pz with the collision force threshold value Pzyz value range. When the collision force value Pz is greater than the collision force threshold value Pzyz value range, it is determined that the vehicle has collided and the vehicle collision information is sent to the cloud server.

[0028] Preferably, after the cloud server receives the automobile engine speed value Zs, the brake temperature value Zwd and the collision force value Pz, it temporarily stores the values ​​in a storage medium set up inside it. When the cloud server receives engine fault information, brake fault information or vehicle collision information, it stores the information in a storage medium set up inside it.

[0029] Preferably, the cloud server sends the engine fault information or brake fault information or vehicle collision information stored therein to the fault output unit through the network, and the fault output unit feeds back the vehicle fault information to the maintenance personnel or the driver through its display screen.

[0030] Preferably, the fault output unit can also be used to accept instructions from maintenance personnel to delete engine fault information or brake fault information or vehicle collision information stored in the cloud server.

[0031] Compared with the prior art, the present invention provides a cloud platform-based automobile fault information management system, which has the following beneficial effects:

[0032] 1. The present invention uses a fault output unit to feed back vehicle fault information to maintenance personnel or drivers through its display screen. By directly feeding back relevant abnormal values ​​to the driver, the driver can intuitively understand the vehicle-related fault problems based on the abnormal values. The driver can feed back the maintenance personnel based on the relevant fault problems they have mastered. The maintenance personnel can prepare corresponding maintenance materials based on the fault information provided by the driver, and can assist the maintenance personnel in quickly repairing the faulty vehicle during the rescue process, thereby shortening the time for vehicle repair and rescue.

[0033] 2. The present invention deletes the engine fault information, brake fault information or vehicle collision information stored in the cloud server through the fault output unit. At the same time, the cloud server can be set to delete the temporarily stored values ​​at a scheduled time, thereby reducing the storage pressure of the cloud server storage space and avoiding the waste of cloud server storage space due to excessive data. The engine fault information, brake fault information or vehicle collision information can be manually deleted by maintenance personnel, thereby preventing these information from being deleted along with the deletion of the temporarily stored values.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 , a car fault information management system based on a cloud platform, including a vehicle data acquisition module, a vehicle data analysis module, a cloud server and a fault output unit;

[0037] The vehicle data acquisition module consists of an engine pulse sensor unit, a brake temperature sensor unit, and a collision sensor unit, among which:

[0038] The engine pulse sensor unit is used to collect the real-time pulse value MC of the engine, the brake temperature sensor unit is used to collect the real-time temperature value WD around the vehicle brake, and the collision sensor unit is used to collect the voltage value Dy output after the collision. After the vehicle data acquisition module collects these data, it is sent to the vehicle data analysis module through the network;

[0039] The vehicle data analysis module is used to analyze the collected data. Specifically, it calculates the vehicle engine speed value Zs, the brake temperature value Zwd and the collision force value Pz according to different algorithm formulas. The specific algorithms are as follows:

[0040] The algorithm formula for the automobile engine speed value Zs is as follows:

[0041] Zs=60*MC*zq

[0042] In the formula, 60 means there are 60 seconds in a minute, and zq means the engine operating cycle, which is the time required for an engine to complete a working cycle in the ignition sequence of each cylinder. Substituting the number of pulses per minute and the engine operating cycle into the formula, the car engine speed value Zs can be calculated;

[0043] The brake temperature value Zwd algorithm formula is as follows:

[0044] Zwd=dy*xs*WD

[0045] In the formula, xs represents the temperature coefficient, and its value is determined by the manufacturer and model of the brake. dy is the voltage signal generated by the brake when braking. dy*xs*WD represents the result obtained by combining the collected temperature values.

[0046] The algorithm formula of collision force value Pz is as follows:

[0047]

[0048] In the formula, mg is the sensitivity of the collision sensor unit, which is used to reflect the sensor's ability to sense input signals. This value is a fixed value. The collision force value when a collision occurs is obtained by dividing the output voltage by the sensitivity.

[0049] The values ​​calculated by the vehicle data analysis module are sent to the cloud server through the network for temporary storage. At the same time, the values ​​are compared with the preset thresholds to determine whether they are abnormal. The specific thresholds are as follows:

[0050] The value range of the car engine speed threshold ZSyz is 5000 to 7000;

[0051] The brake temperature threshold ZDyz ranges from 200°C to 300°C;

[0052] The collision force threshold Pzyz ranges from 5g to 10g.

[0053] Among them, the threshold of automobile engine revolutions, the threshold of brake temperature and the threshold of collision force can be set with different corresponding thresholds according to specific brands and models;

[0054] The criteria for determination are as follows:

[0055] The vehicle data analysis module compares the calculated brake temperature value Zwd with the brake temperature threshold ZDyz. When the brake temperature value Zwd is greater than the brake temperature threshold ZDyz, it is determined that the brake is abnormal and the brake fault information is sent to the cloud server.

[0056] The vehicle data analysis module compares the calculated vehicle engine speed value Zs with the vehicle engine speed threshold ZSyz. When the vehicle engine speed value Zs is greater than the vehicle engine speed threshold ZSyz, it is determined that the engine is abnormal, and the engine fault information is sent to the cloud server;

[0057] The vehicle data analysis module compares the calculated collision force value Pz with the collision force threshold value Pzyz value range. When the collision force value Pz is greater than the collision force threshold value Pzyz value range, it is determined that the vehicle has collided, and the vehicle collision information is sent to the cloud server;

[0058] After receiving engine fault information, brake fault information or vehicle collision information, the cloud server stores it in its internal storage medium. The cloud server is connected to the fault output unit through a network. When a vehicle fails, the fault output unit will feedback the fault data to the maintenance personnel or the driver through its display screen. By directly feeding back the relevant abnormal values ​​to the driver, the driver can intuitively understand the vehicle-related fault problems based on the abnormal values. The driver can feedback to the maintenance personnel based on the relevant fault problems they have mastered. The maintenance personnel can prepare corresponding maintenance materials based on the fault information provided by the driver, and then during the rescue process, they can assist the maintenance personnel to quickly repair the faulty vehicle, thereby shortening the time for vehicle repair and rescue.

[0059] After the maintenance personnel completes the vehicle maintenance, they can delete the engine fault information, brake fault information or vehicle collision information stored in the cloud server through the fault output unit. At the same time, the cloud server can be set to delete the temporarily stored values ​​at a scheduled time, thereby reducing the storage pressure of the cloud server storage space and avoiding excessive data from wasting the cloud server storage space. The maintenance personnel can manually delete the engine fault information, brake fault information or vehicle collision information, thereby preventing this information from being deleted along with the temporarily stored values.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
