Because the single-phase cost control intelligent electric energy meter has a complex structure and multiple production process steps, the single-phase cost control intelligent electric energy meter not only relates to the installation and the test of components in the production process, but also comprises the debugging of software and hardware, if a certain step goes wrong, the yield of the whole production line is caused, and the existing production management system is difficult to track which step goes wrong, so that the targeted improvement cannot be realized.
Disclosure of Invention
The invention aims to solve the technical problem of providing a production management system of a single-phase cost-control intelligent electric energy meter, which reduces the production cost and improves the product quality and reliability, aiming at the defects of the prior art.
The invention solves the technical problem and adopts the technical scheme that a production management system of a single-phase cost control intelligent electric energy meter is provided, which comprises the following steps:
an MCU internal sequence number generation module; the MCU internal serial number is generated when a self-contained program is burnt for the MCU of the single-phase cost control intelligent electric energy meter;
a process recording module; the process recording module records operation information of each process of the single-phase cost control intelligent electric energy meter; the operation information corresponds to the MCU internal serial number;
a detection module; whether the preset operation information corresponding to the internal serial number of the MCU corresponds to the operation information recorded by the process recording module or not is detected during the last process of the single-phase cost control intelligent electric energy meter.
Further, the MCU internal serial number is also associated with the meter number of each single-phase cost control intelligent electric energy meter.
Further, the MCU internal serial number comprises a production date, supplier information and/or vendor information.
Further, the operation information includes operation time, test data, and an operator.
Further, the MCU internal serial number is read out through a communication mode.
Compared with the prior art, the invention has the following beneficial effects: the method comprises the following steps of utilizing the procedure which is required to be carried out by each single-phase cost control intelligent electric energy meter, namely, generating a self-defined internal serial number when a program is burnt into the MCU; the subsequent production and assembly process of each single-phase cost control intelligent electric energy meter is hooked with the MCU internal serial number, and once a subsequent fault occurs, all production processes of the meter can be traced back by inquiring the MCU internal serial number of the fault meter. Meanwhile, compared with the traditional mode of monitoring the production flow by pasting the bar codes, the method can reduce the cost and the working procedure, and the internal serial number cannot be directly seen by an operator, so that the operator must treat each table equally.
Drawings
FIG. 1 is a flow chart of a process for producing a single-phase cost-controlled smart meter according to a preferred embodiment of the present invention.
Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
The single-phase cost control intelligent electric energy meter is generally provided with an intelligent control chip such as an MCU (microprogrammed control unit), and the functions of electric energy metering, information storage and processing, real-time monitoring, automatic control, information interaction and the like are realized through the MCU intelligent control chip. The programs for implementing these functions are usually programmed into the MCU.
In the preferred embodiment, an MCU internal serial number is generated when the MCU of the single-phase cost-control intelligent electric energy meter is burned with a self-contained program. Namely, the MCU of each single-phase cost control intelligent electric energy meter corresponds to an MCU internal serial number. The MCU internal serial number is stored in the MCU and can be read out through a communication mode. There are various communication methods for reading, and the communication method may be a wired communication or a wireless communication.
The single-phase cost control intelligent electric energy meter has multiple assembling processes, and assembling personnel, assembling requirements and assembling time of each assembling process are different. In the assembling process of each assembling procedure, the operation information of each assembling procedure, such as operation time, procedure name, operator information, procedure test data information and the like, is recorded through the procedure recording module.
And setting a detection module in the last packaging process, namely detecting whether the operation information of each preset process corresponding to the MCU internal serial number stored in the MCU of each single-phase cost control intelligent electric energy meter corresponds to the actual operation information recorded by the process recording module. If the two lists are corresponding, the two lists are judged to be qualified lists, and if the two lists are not corresponding, the two lists are judged to be unqualified lists.
So, even break down in follow-up single-phase expense accuse intelligent ammeter's use, this fault table also can be convenient through reading the inside sequence number of MCU backtrack to when first equipment each item operational information of record, and then can judge that the fault that leads to of which process takes place to improve the process of changing the directions and promote the yields.
Compared with the traditional mode of distinguishing and monitoring the production process of each single-phase cost-control intelligent electric energy meter by printing or spraying bar codes, two-dimensional codes and the like on the body of each single-phase cost-control intelligent electric energy meter, the MCU internal serial number has uniqueness, non-tamper property and invisibility; because the internal serial number of the MCU is built in the MCU, an operator cannot know the specific internal serial number of the MCU, so that the operator has to treat each single-phase cost-control intelligent electric energy meter to be assembled equally. And extra processes and cost are not needed in the process of generating the MCU internal sequence number.
Referring to fig. 1, fig. 1 shows a specific workshop production process flow chart of the single-phase cost-controlled intelligent electric energy meter of the present invention. It includes:
step 1: burning an MCU program and generating an MCU internal serial number;
step 2: packaging the MCU chip;
and step 3: testing a basic function;
and 4, step 4: precision adjustment
And 5: carrying out voltage withstanding test;
step 6: aging detection;
and 7: precision recalibration
And 8: comparing and testing;
and step 9: and (6) packaging.
The operation information and the detection data of each step are recorded for tracing the fault source at a later date.
After the method is adopted, the factory inspection qualification rate of the single-phase cost-control intelligent electric energy meter reaches more than 99.95%, so that the cost is reduced by more than 13%.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
