Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the scope of protection of the present disclosure. The technical solution of the present disclosure is described in various aspects below with reference to various figures and embodiments.
The terms "first", "second", and the like are used hereinafter only for descriptive distinction and not for other specific meanings.
Fig. 1 is a schematic flow chart of an embodiment of a remote work machine operation state analysis method according to the present disclosure, as shown in fig. 1:
The engineering machinery can be an excavator and the like, and the vehicle-mounted terminal can be various terminal devices. The server generates a remote configuration parameter group file, wherein the remote configuration parameter group file comprises a first data frame, a first acquisition frequency, a first parameter group, a data acquisition starting time and the like. The first parameter group is used for setting parameters needing to be collected, and the parameters comprise engine rotating speed, current, hydraulic system pressure and the like.
The server sets a message TLV (Type/Length/Value) format corresponding to the remote configuration parameter group file, encapsulates the remote configuration parameter group file according to the message TLV format and sends the remote configuration parameter group file to the vehicle-mounted terminal. The remote configuration parameter set file may be encrypted, a password set, and a separate encryption may be performed for the first parameter set.
And 102, receiving first operation state data uploaded by the vehicle-mounted terminal, wherein the vehicle-mounted terminal collects the first operation state data based on the remote configuration parameter group file.
And 103, analyzing and processing according to the first operation state data. The analysis processing comprises fault diagnosis processing, working condition research processing and the like.
And 104, after the analysis processing is finished, sending a collection reduction message to the vehicle-mounted terminal so that the vehicle-mounted terminal collects and uploads second running state data based on the vehicle-mounted terminal parameter group file.
Before sending the remote configuration parameter set file to the vehicle-mounted terminal of the engineering machinery, the vehicle-mounted terminal collects and uploads second operation state data based on the vehicle-mounted terminal parameter set file. The vehicle-mounted terminal parameter set file may be configured and stored in the vehicle-mounted terminal when the engineering machine leaves a factory, and the vehicle-mounted terminal parameter set file includes a second data frame, a second acquisition frequency, a second parameter set, and the like. The first acquisition frequency is typically greater than the second acquisition frequency, and the number of parameters in the first set of parameters is typically greater than the number of parameters in the second set of parameters.
In one embodiment, if an alarm message sent by the vehicle-mounted terminal is received or a fault is judged to occur based on the second operation state data, the engineering machinery is judged to have a fault; and if the monitoring instruction is received, determining that the working condition research processing is required. And when the engineering machinery is judged to have faults or needs working condition research processing, generating a remote configuration parameter group file and sending the remote configuration parameter group file to the vehicle-mounted terminal.
And in a normal working state of the engineering machine, the vehicle-mounted terminal collects data according to a vehicle-mounted terminal parameter group file configured by a factory and sends the data to the server. When the engineering machinery fails, gives an alarm and needs to perform working condition analysis, the server can screen out data needing to be analyzed according to the vehicle maintenance guide library and reconfigure the data needing to be analyzed to obtain at least one remote configuration parameter group file.
The remote configuration parameter set file comprises a first data frame, a first acquisition frequency, a first parameter set and the like, and is compiled in a TLV format. For example, a CAN frame uploaded by a master controller and the like exists in a CAN bus of the engineering machine, and the CAN frame has eight bytes, and each byte bears one or more parameters. The first data frame is used for setting a target frame, the first parameter group is used for setting parameters needing to be acquired, and the parameters can be vehicle speed, engine rotating speed, hydraulic system pressure data and the like; determining the byte needing to be transmitted in the CAN frame, wherein the bit position 1 corresponding to the byte is not required to be transmitted to be 0, so that the condition that 8 bytes of data of the CAN frame are all uploaded is avoided, and the parameter configuration is realized.
Fig. 2 is a schematic flow chart of an analysis process in an embodiment of a remote work machine operation state analysis method according to the present disclosure, as shown in fig. 2:
The first operating state data includes vehicle speed, engine speed, hydraulic system pressure data, etc., and may generate a data profile corresponding to the vehicle speed, engine speed, hydraulic system pressure data, respectively.
Basic data of the construction machine in a normal operation state, for example, basic data of a vehicle speed, an engine speed, hydraulic system pressure data, and the like of the construction machine in a normal operation state are stored in advance.
And step 203, performing fault diagnosis processing based on the comparison and analysis result.
For example, a comparison analysis is performed using the basic data and the data transformation curve, and if a difference between values on the basic data and the data transformation curve is greater than a preset threshold, it is determined that a fault occurs.
And when the analysis processing is working condition research processing, generating a data change curve corresponding to the first operation state data, and analyzing based on the data change curve for carrying out the working condition research processing. The working conditions of the engine, the hydraulic system and the like can be researched.
Fig. 3 is a schematic flow chart of troubleshooting in an embodiment of the remote engineering machine operation state analysis method according to the present disclosure, as shown in fig. 3:
For example, the engine speed basic data and the engine speed data conversion curve are compared and analyzed, if the difference value between the values on the engine speed basic data and the engine speed data conversion curve is larger than a preset threshold value, it is determined that an engine fault occurs, and maintenance guide information corresponding to the engine fault can be acquired through an expert system.
When fault diagnosis processing is carried out, the server compares the generated data transformation curve with basic data of the engineering machinery in a normal working state, locates a fault point, provides maintenance guide information, transmits the maintenance guide information to the vehicle-mounted terminal, and transmits the maintenance guide to a display in the engineering machinery for displaying.
For example, after the maintenance guidance information is sent to the vehicle-mounted terminal, new engine speed basic data is received, and an engine speed data conversion curve corresponding to the engine speed basic data is continuously generated; and continuously using the engine rotating speed basic data and the engine rotating speed data conversion curve for comparison and analysis, and determining that the engine fault is eliminated and the fault diagnosis processing is finished if the difference value of the values on the engine rotating speed basic data and the engine rotating speed data conversion curve is smaller than a preset threshold value.
And step 304, sending the acquisition and restoration message to the vehicle-mounted terminal.
After the working condition research processing is completed, the acquisition and restoration message can be sent to the vehicle-mounted terminal. And after receiving the acquisition and reduction message, the vehicle-mounted terminal restores the vehicle-mounted terminal parameter set file, and acquires and uploads second running state data based on the vehicle-mounted terminal parameter set file.
In one embodiment, in the prior art, data uploaded to a server is stored in a single dimension by taking time as a unit, and the server stores the data in sequence according to a time sequence on the basis of a time axis; the problem of difficult data extraction exists when field condition data (such as rotating speed, current, pressure and the like) need to be analyzed.
According to the method, the remote configuration parameter group file is transmitted to the vehicle-mounted terminal in a remote flash mode, the vehicle-mounted terminal collects data sent by a bus node according to a first collection frequency in the remote configuration parameter group file, the vehicle-mounted terminal packages the collected data after storing the collected data locally to generate first running state data and uploads the first running state data to the server, and the server is sequentially filled with the data according to a set two-dimensional space, so that data extraction can be rapidly achieved, and curves can be drawn. For example, a two-dimensional array is generated in advance, a first dimension of the two-dimensional array represents time, a second dimension of the two-dimensional array represents operating state data, and the first operating state data is stored by using the two-dimensional array.
In one embodiment, the engineering machine is an excavator, and the vehicle-mounted terminal operates according to a vehicle-mounted terminal parameter set file configured by a factory in a normal working state of the excavator. When the excavator has a fault alarm, the server screens out data to be analyzed according to the vehicle maintenance guide library, and reconfigures the data to be analyzed to obtain at least one remote configuration parameter group file which is mainly used for adjusting data frames, acquisition frequency, parameter groups and the like in the vehicle-mounted terminal parameter group file, wherein the remote configuration parameter group file is compiled in a TLV format. If the corresponding byte in the CAN frame needs to be transmitted, the bit position 1 corresponding to the byte in the remote configuration parameter group file does not need to be transmitted to be 0, so that the defect that all 8 bytes of data of the CAN frame are uploaded is avoided, and the parameter configuration is realized.
As shown in fig. 4, the in-vehicle terminal is connected to a component of the construction machine through a bus, and the component may be an engine, a controller, a display, or the like. And the vehicle-mounted terminal collects the state data message sent by the component on the bus based on the remote configuration parameter group file, integrates and uploads the state data message.
The system framework is connected by a CAN bus, the vehicle-mounted terminal CAN be a 4G terminal and the like, receives bus data sent by an engine, a controller and a display according to a vehicle-mounted terminal parameter group file which is flashed from a factory, and transmits the bus data to the server according to an uploading period set in the vehicle-mounted terminal parameter group file. And when a fault occurs or working condition analysis is needed, the server transmits the updated remote configuration parameter group file to the 4G terminal and displays the diagnosis result on an in-vehicle display.

The server compiles a remote configuration parameter group file, the remote configuration parameter group file comprises the contents of required configuration parameter frequency, CAN frame transmission, parameter group number, data acquisition starting time, data length and the like, and the remote configuration parameter group file adopts a TLV encoding format. And the server transmits the configured remote configuration parameter group file to the vehicle-mounted terminal in a remote mode.
In step 503, the in-vehicle terminal receives the diagnosis request sent by the server.
And step 504, the vehicle-mounted terminal receives message information sent by the bus node according to the remote configuration parameter group file, packages the message information and uploads the message information to the server.
After receiving the remote configuration parameter group file transmitted by the server, the vehicle-mounted terminal receives message information on the CAN bus according to the requirement of the remote configuration parameter group file, packages the message information into first operation state data, and uploads the first operation state data to the server.
And 505, the server stores the received message information according to a two-dimensional space.
The server stores the received first running state data according to a two-dimensional space, namely, a two-dimensional array is generated, the first dimension of the two-dimensional array corresponds to time, and the second dimension corresponds to data in the running state data, including current, pressure, rotating speed and the like. And storing the received first operation state data in a two-dimensional array.
Data can be conveniently extracted from the two-dimensional array, a time axis is taken as an abscissa, each acquired data (current, pressure, rotating speed and the like) is taken as an ordinate, a change curve is automatically drawn, and the change curve is compared with basic data, stored by a server, of the engineering machinery in a normal working state, so that data support is provided for fault accurate diagnosis and working condition research.
