A vehicle type configuration corresponds to the measurement mode of a measurement procedure, often need the same vehicle type every time a configuration appears, need to compile a set of test procedure; when a programmer compiles a program, program setting change caused by data change needs to be updated in all measuring program segments, manual updating of the programmer is easy to miss, and workload is huge; in addition, vehicle type configuration information needs manual judgment of an operator, configuration information of similar configuration is easy to confuse, and accordingly the existing vehicle body part measuring mode is large in workload and high in error rate. The technique may be implemented by associated software or hardware, and is described below by way of example.
Referring to FIG. 1, a flow chart of a method of measuring a vehicle body component; the method is applied to the PLC of the measuring workstation; the method comprises the following steps:
step S102, collecting identity information of a measured object;
the object to be measured may be a part constituting a vehicle, such as a body-in-white, a door, a front cover, a rear cover, etc.; before a measured object enters a measuring workstation, a label, such as a graphic label (including a two-dimensional code and a bar code), an electronic label and the like, is arranged on the measured object in advance; the tag can mark the identity information of the object to be measured, such as the vehicle type, configuration, state information, vehicle number and the like of the object to be measured, so that the PLC convenient for measurement can automatically identify the identity information of the object to be measured and find a corresponding program according to the identity information of the object to be measured to measure; the label is arranged, so that the object to be detected can be tracked and monitored in real time, the progress condition of the object to be detected can be acquired in time, and the production line can be managed and adjusted in a unified manner.
Step S104, judging whether the identity information is matched with a measurement task issued in advance;
a Manufacturing Execution System (MES) System generally issues a measurement task to a measurement workstation; the measurement task usually carries information such as vehicle type configuration of a measurement object; in order to prevent the identity information and the measurement task of the object to be measured from causing a measurement error, it is necessary to first determine whether the identity information of the object to be measured matches with the measurement task issued in advance, and when the identity information matches with the measurement task issued in advance, the following operations can be performed.
Step S106, if so, analyzing to obtain configuration information corresponding to the identity information, sending the configuration information to the measurement control system, so that the measurement control system obtains a measurement program matched with the identity information from a measurement program library stored in advance, and measuring the measured object according to the measurement program; wherein, the measuring program library stores general programs and special programs.
The measurement program library usually stores program blocks which may be used for measuring all configurations of a vehicle type; for example, vehicle type A includes an economy configuration, a comfort standard configuration, and a luxury configuration; when testing the tested object corresponding to the economic configuration, the program block 1 and the program block 2 in the general program and the special program corresponding to the economic configuration may be used; in testing the object under test corresponding to the luxury configuration, the block 2, the block 3, and the block 4 in the general-purpose program, and the special-purpose program corresponding to the luxury configuration may be used.
When the identity information is matched with a measurement task issued in advance, the PLC of the measurement workstation can analyze the configuration information corresponding to the identity information and send the configuration information to a measurement control system, the measurement control system is generally installed in a control cabinet of a measuring machine, the measurement control system calls a general program and a special program matched with the identity information from a measurement program library stored in advance, and a measured object is measured according to a measurement range program.
According to the measuring method of the vehicle body part, provided by the embodiment of the invention, the measuring control system is pre-stored with the measuring program library, and after the PLC acquires the identity information of the measured object, the PLC judges whether the identity information is matched with a pre-issued measuring task; if so, sending the configuration information corresponding to the identity information to a measurement control system, acquiring a measurement program matched with the identity information from a measurement program library by the system, and measuring the measured object according to the measurement program; wherein, the general program and the special program are stored in the measuring program library. The method calls out the required measuring program blocks from the program library according to different vehicle type configurations, reduces the workload of programming the measuring program, and simultaneously reduces the error rate of the program.
Referring to FIG. 2, a flow chart of another method of measuring a vehicle body component is shown; the method is implemented on the basis of the method shown in fig. 1, which is applied to the PLC of the measurement workstation; in the method, firstly, a measurement program library is established through steps S202 and S204, and the method comprises the following steps:
step S202, decomposing a measurement program of the vehicle body parts of the same vehicle type into a general program and a special program by adopting PC-DMIS measurement software;
the steps are that a measurement program library is established, a PC-DMIS secondary development function is used, a body-in-white and part measurement program of the same vehicle type is decomposed into a general program and a special program, flexible measurement is realized, and management and configuration of a measurement workstation are facilitated; generally, a measurement program library is established for the same vehicle type, and when configuration information changes, program setting changes caused by all data changes only need to be uniformly changed in the program library corresponding to the vehicle type; when the same vehicle type has only one program library and brand new configuration, the requirement can be met only by updating the configuration list or adding new program blocks.
Step S204, storing the general program and the special program as a measurement program library of the current vehicle type;
specifically, the measurement library is a module-based storage of measurement programs, i.e., blocks; the modular measuring program includes but is not limited to an independent measuring program, a subprogram set, an integrated measuring program made in a high-level measuring programming language, and the like, which are stored in a module form; the storage form of the program block includes but is not limited to local storage, network storage, removable media storage, etc.
Step S206, reading the RFID label arranged on the object to be tested through the RFID reader-writer to obtain identity information;
as shown in the schematic overall structure diagram of the measurement workstation shown in fig. 3, an RFID reader (in fig. 3, an ultra-high frequency RFID reader is taken as an example) may be disposed at an entrance of the measurement workstation, and is in communication connection with the PLC; before a measured object enters a measuring workstation, an RFID label is adhered to the measured object, the RFID label is used for storing identity information of the measured object, can be adhered to the measured object and can also be adhered to a measuring support, and the identity information of the measured object comprises vehicle state information, vehicle numbers and the like; the method comprises the following steps that a measured object enters a measuring workstation, and an RFID reader-writer reads an RFID label pasted on the measured object to obtain identity information stored in the RFID label; the RFID reader-writer can use a high-frequency or ultrahigh-frequency reader-writer, the reading-writing mode can be combined with an AGV (automatic Guided Vehicle) or other delivery vehicles to realize automatic reading-writing, and the handheld RFID reader-writer can also be used for manual reading-writing.
Step S208, judging whether the identity information is matched with the measurement task; if not, executing step S210; if yes, go to step S212; specifically, the PLC of the measurement workstation compares the identity information on the RFID tag of the object to be measured read by the RFID reader with the measurement task issued by the MES system, and judges whether the identity information is matched with the measurement task.
Step S210, generating an alarm signal to enable the object to be measured to return to the welding line;
when the identity information is not matched with the measurement task issued in advance, the PLC of the measurement workstation sends an alarm signal and prompts the measured object to return to the welding line; generally, vehicle state information and vehicle numbers stored in the RFID electronic tags are compared with measurement order requirements directly issued by an MES; the reasons for mismatching the identity information with the measurement task are roughly divided into two types, one of which is the error sending of the measured object; the second is that the welding line temporarily changes the vehicle number, resulting in the discrepancy between the vehicle number and the vehicle state information.
And step S212, analyzing the configuration information corresponding to the identity information, sending the configuration information to a controller of the measuring machine, so that the controller extracts the general program and the special program matched with the identity information from the measuring program library, and controlling the corresponding measurer to measure the measured object according to the general program and the special program.
Specifically, the analyzed configuration information is transmitted to a measurement control system, a measurement task is controlled by the measurement control system, the measurement control system is installed in a control cabinet of the measuring machine, consists of electronic elements such as a PLC (programmable logic controller) and the like and is provided with special control software, and the measurement control system calls a corresponding measurement program block from a measurement program library to carry out measurement; for example, a schematic of the structure of a measurement library for a body part as shown in FIG. 4; the measurement library includes a plurality of blocks, for example, a block 1 is an MT (manual Transmission) nacelle block, and a block 2 is an AT (Automatic Transmission) nacelle block. When the RFID configuration information is comfort standard configuration, the control system can call 2, 4, 6, 9, 10 and 14 program blocks from a program library; when the RFID configuration information is a hybrid luxury configuration, the control system may call 3, 4, 8, 9, 13, 14 blocks from the library.
The method realizes that one program library is established for the same vehicle type, and the program setting changes caused by all data changes only need to be changed in the program library in a unified way; establishing a program library, wherein only one program library is arranged in the same vehicle type, and when brand new configuration occurs, the requirement can be met only by updating a configuration list or adding a new program block; reading the information of the measured object by using an RFID reader-writer, and comparing the information with a measurement task issued by an MES (manufacturing execution system) to avoid misjudgment during manual identification; the workload and the error rate of the existing vehicle body part measuring mode are reduced.
The embodiment of the invention also provides another measuring method of a vehicle body component, which is realized on the basis of the method shown in the figure 1 or the figure 2, and as shown in the figure 5, the method comprises the following steps:
step S502, the measured object enters a measuring workstation;
step S504, the RFID reader-writer identifies object information;
step S506, comparing whether the object information is consistent with the MES task; if yes, go to step S508; if not, executing step S510;
