When the characteristic data corresponding to the second identification piece appears in the data detected by the detection device, the detection device can be considered to detect the second identification piece, and the production beat monitoring device records the moment as the second moment when the material bearing device leaves the station. The number of the material bearing devices can be multiple, and the material bearing devices sequentially move to each station.
Specifically, in this embodiment, the first identification component is an electronic tag carrying first identification information, the second identification component is an electronic tag carrying second identification information, the detection device is a wireless radio frequency card reader, and the process of the production beat monitoring device acquiring the first time when the material carrying device arrives at each station and the second time when the material carrying device leaves each station includes: the production beat monitoring device obtains the moment when the wireless radio frequency card reader of each station detects the first identification information as a first moment, and the production beat monitoring device obtains the moment when the wireless radio frequency card reader of each station detects the second identification information as a second moment.

And S20, the production beat monitoring device determines beat characteristic parameters of the production system according to the first time and the second time corresponding to each station.
The tempo characteristic parameters refer in particular to data relating to the production tempo of the production system. In the present embodiment, the beat feature parameters specifically include, but are not limited to, the following parameters: station beat time, bottleneck station information (such as bottleneck station time, bottleneck station ranking information and the like), balance rate of the production system and line stop times.
Specifically, the production tempo monitoring device may calculate an interval duration between a first time and a second time corresponding to each station, an interval duration between first times corresponding to two adjacent stations, an interval duration between second times corresponding to two adjacent stations, an interval duration between a second time of a previous station and a first time of a next station in the two adjacent stations, and the like, and determine a tempo characteristic parameter of the production system based on the calculated parameter.
The first time and the second time of different stations are different, the corresponding beat characteristic parameters are different, the corresponding relation between the first time and the second time corresponding to each station and the beat characteristic parameters can be pre-established and stored in the production beat monitoring device, and the production beat monitoring device can determine the beat characteristic parameters of the production system corresponding to the first time and the second time corresponding to each current station based on the corresponding relation.
In the production rhythm monitoring method provided by the embodiment of the invention, in the process that a material bearing device sequentially moves to each station, the production rhythm monitoring device is used for acquiring the time that a detection device of each station respectively detects a first identification piece and a second identification piece of the material bearing device so as to obtain the first time when the material bearing device reaches each station and the second time when the material bearing device leaves each station, the first identification piece and the second identification piece are arranged at intervals along the moving direction of the material bearing device, and the automatically moving material bearing device on a production line does not leave the stations before the process when reaching the stations.
Specifically, in an embodiment, the beat characteristic parameter includes a workstation beat time corresponding to each workstation, and step S20 includes:
and S21, calculating an absolute difference value of the first time and the second time corresponding to each station by the production beat monitoring device, wherein the absolute difference value is the beat time of each station.
The station takt time specifically refers to the time taken for completing corresponding processing on the product on the material carrying device according to the procedure corresponding to the station.
For example, when the plurality of stations include a station 1, a station 2 and a station 3, the time when the detection device corresponding to the station 1 detects the first identification member of the material carrying device is T1, and the time when the detection device corresponding to the station 1 detects the second identification member of the material carrying device is T2, the material carrying device reaches the station 1 at the time T1, the product on the material carrying device performs the processing of the process corresponding to the station 1 in the time period from T1 to T2, and leaves the station 1 at the time T2; the time when the detection device corresponding to the station 2 detects the first identification piece of the material carrying device is T3, the time when the detection device corresponding to the station 2 detects the second identification piece of the material carrying device is T4, the material carrying device reaches the station 2 at the time of T3, the product on the material carrying device executes the processing of the procedure corresponding to the station 2 in the time period from T3 to T4, and leaves the station 2 at the time of T4; the moment when the detection device corresponding to the station 3 detects the first identification piece of the material carrying device is T5, the moment when the detection device corresponding to the station 3 detects the second identification piece of the material carrying device is T6, the material carrying device reaches the station 3 at the moment of T5, the product on the material carrying device performs processing of a procedure corresponding to the station 3 in a time period from T5 to T6, and leaves the station 3 at the moment of T6. When the material carrying devices are multiple, the material detection devices detected by each station at the same time point are different material carrying devices. Based on this, the production beat monitoring device can calculate that the workstation beat time corresponding to the workstation 1 is | -T1-T2 |, the workstation beat time corresponding to the workstation 2 is | -T3-T4 |, and the workstation beat time corresponding to the workstation 3 is | -T5-T6 |.
Here, through the above step S21, without manual operation, the station tact times of the plurality of stations can be determined quickly and accurately based on the parameters detected by the machine, so that the tact detection data is improved while the accuracy of measuring the station tact times is ensured.
Further, the beat characteristic parameter further includes bottleneck station information, and after determining station beat time, step S20 may further include:
s22, acquiring the standard station takt time of the production system by the takt monitoring device;
the standard station tact time refers to an upper limit value of a time period allowed for each station of the production system to perform its process.
The standard workstation takt time can be customized by a user, and the production takt monitoring device can also obtain the hourly output P set in the production process execution management system of the manufacturing enterprise, and data obtained according to 3600/P x 0.9 is used as the standard workstation takt time.
And S23, selecting the station takt time which is greater than the standard station takt time from the station takt time corresponding to each station by the production takt monitoring device, wherein the station takt time which is greater than the standard station takt time is the bottleneck station time.
The production beat monitoring device compares the obtained station beat time corresponding to each station with the standard station beat time respectively, and station beat time with a value larger than the standard station beat time indicates that the corresponding station working beat time is too long and can be regarded as a bottleneck station.
When the station takt time greater than the standard station takt time is one, the production takt monitoring device directly takes the station takt time as the bottleneck station time, and when the station takt time greater than the standard station takt time is multiple, the production takt monitoring device can take all corresponding station takt times as the bottleneck station time.
Here, through the above steps S22 to S23, the bottleneck station time can be quickly and accurately determined based on the parameters detected by the machine without manual operation, so that the data detected by the beat is improved and the accuracy of measuring the station beat time is ensured.
Further, the bottleneck information includes bottleneck station ranking information in addition to the bottleneck station time, and after S23, S20 further includes:
step S24, when a plurality of station takt times are all larger than the standard station takt time, the production takt monitoring device determines a plurality of bottleneck stations which are in one-to-one correspondence with the station takt times;
that is, each station corresponding to a station takt time greater than the standard station takt time is a bottleneck station.
S25, acquiring the times that the station takt time corresponding to each bottleneck station in a set time length is greater than the standard station takt time by the production takt monitoring device;
the set duration can be set according to actual requirements. The set time length can use the current time as a timely starting point, can also use the current time as an end point of the set time length timing, and can also be a certain specified time period. The station beat time of each station and the station beat time which is greater than the standard station beat time are continuously obtained within the set time according to the mode in the embodiment, and the bottleneck times corresponding to the station are increased by 1 every time the station beat time is greater than the standard station beat time.
And S26, sequencing the corresponding times of each bottleneck station by the production beat monitoring device according to the set size sequence to obtain bottleneck station ranking information.
The set size sequence can be the sequence of the workstation takt time from large to small, and can also be the sequence of the workstation takt time from small to large. For example, when a plurality of stations include station 1, station 2 and station 3, in setting for duration, the number of times that station takt time of station 1 is greater than standard station takt time is 2, the number of times that station takt time of station 2 is greater than standard station takt time is 0, the number of times that station takt time of station 3 is greater than standard station takt time is 3, set for big or small order to set up the time from hour to hour, can obtain bottleneck station ranking information based on this and be: station 3 (3 times), station 1 (2 times).
In this embodiment, through steps S24 to S26, the ranking information of the bottleneck stations can be quickly and accurately determined based on the parameters detected by the machine without manual operation, so as to visually locate the positions and conditions of the bottleneck stations and reduce the data analysis process of a process engineer, thereby subsequently solving the problem of the beats in the production system in a targeted manner based on the ranking information of the bottleneck stations.
Further, the tempo characteristic parameters include a balance rate of the production system in addition to the bottleneck station information and the station tempo time, and after step S23, step S20 further includes:
step S201, a production beat monitoring device obtains the total number of stations;
the total number of workstations may be specified as a user preset parameter.
And S202, the production beat monitoring device calculates the balance rate according to the station beat time, the bottleneck station time and the total number of stations corresponding to each station.
Specifically, the production tempo monitoring device can calculate the sum ST of the tempo times of all the stations based on the station tempo time corresponding to each station. The production cycle monitoring device calculates the total NT of the bottleneck station times based on all station cycle times greater than the standard cycle time. The equilibrium rate note = ST/(NT total number) 100%.
Here, through step S201 and step S202, the balance condition of the production system can be determined quickly and accurately without user operation, and measures are taken in time based on the balance condition of the entire production system to eliminate the efficiency loss or the abnormality of the overproduction between jobs, thereby ensuring the efficient operation of the production system.
Further, besides the bottleneck station information, the station tact time and the balance rate of the production system, the tact characteristic parameter further includes the number of stop lines, and after step S21, step S20 further includes:
step S203, the production beat monitoring device acquires the standard station beat time of the production system;
when step S20 further includes step S22, step S203 may be the same as step S22, and the sequence of steps S23 to S26 and step S204 is not particularly limited.
And step S204, when the station takt time of each station is greater than the standard station takt time, the production takt monitoring device increases the wire stopping times once to obtain the increased wire stopping times.
The number of line stops refers to the number of times that the material carrying device stops moving between different posts.
When the material carrying devices move in different stations respectively, the production beat monitoring device can determine the real-time station beat time of each station based on the first time and the second time of each station acquired in real time, and when the abnormal time of the following station is too long, the material carrying devices on the previous stations can be influenced to continue moving backwards, so that the more and more station beat times of the stations exceed the standard station beat time. Based on this, when the station takt time of all stations all is greater than standard station takt time, can lead to the material to bear the weight of the device and stop to remove between different stations, lead to appearing stopping the line condition. The initial number of the wire stopping times is 0, and the production beat monitoring device can increase the one-time wire stopping times when the one-time wire stopping condition occurs.
Here, through the above steps S203 to S204, the production line stop condition can be timely and accurately recorded without user operation, so as to further improve the measurement efficiency of the beat condition of the production system, and provide more comprehensive abnormality analysis data for subsequent abnormality disposal of the production system.
Further, based on the foregoing embodiment, the present application further provides another embodiment of a method for monitoring a tact, where in this embodiment, after step S20, the method further includes:
and step S30, the production beat monitoring device outputs prompt information according to the beat characteristic parameters.

When the production beat monitoring device outputs the station beat time and the bottleneck station information of each station, the station identification (such as a serial number, a post name and the like) of the station and the station beat time or the bottleneck station information can be output in a correlation mode, and therefore a user can quickly locate the station with problems based on the output station identification. The detection device of each station can be provided with an information input module for setting station identification of each station.
Further, the beat characteristic parameter includes bottleneck station information, and step S30 includes: the production beat monitoring device determines the set identity information related to the station corresponding to the bottleneck station information; the production beat monitoring device determines a terminal for receiving prompt information according to the set identity information; and sending prompt information to the terminal. Specifically, different stations can be associated with different set identity information, wherein a plurality of stations can be associated with one set identity information correspondingly. The identity information of the manager of the corresponding station is set, on the basis of the identity information, the production beat monitoring device takes the terminal (such as a mobile phone, a computer and the like) associated with the set identity information as the terminal for receiving the prompt information, and sends the prompt information to the terminal, so that the manager of the station with the bottleneck can timely know the abnormal condition of the station managed by the manager and timely dispose the abnormal condition based on the terminal without looking up the specified equipment (such as a display board of a workshop), and the overall production efficiency of the production system is further ensured
