Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An after-market monitoring system for a device according to an embodiment of the first aspect of the invention is described below with reference to the drawings.
Fig. 1 is a block diagram of an after-market monitoring system of a device according to an embodiment of the present invention, and as shown in fig. 1, an after-market monitoring system 100 of a device according to an embodiment of the present invention includes a master control apparatus 10, a storage apparatus 20, and a monitoring apparatus 30.
The main control device 10 is configured to collect operation parameters of a load of a device, and encode and compress the operation parameters. For example, for a refrigerator, the main control board may collect, in real time, operating parameters of each load of the refrigerator, including, for example, key information such as on-off time, heater on-time and maintenance time, fan state, damper state, sensor temperature value, and the like. In order to transmit the collected operation parameters of the load to the storage device 20 and to transmit data with fewer data frames and increase the transmission speed, in an embodiment of the present invention, the master control device 10 performs encoding compression on the operation parameters, for example, compresses the operation parameters by using a normal data compression method or a preset encoding compression method, and transmits the compressed operation parameters to the storage device 20, and the storage device 20 is configured to receive and store the encoded and compressed operation parameters.
In some embodiments, the storage device 20 may include a Secure Digital Memory Card (SD/SD Card), the SD Card is added to the main control device 10, the main control device 10 writes the collected real-time operation parameters into the SD Card and stores the real-time operation parameters, and the SD Card may be written into the SD Card once every preset time, for example, one hour, in order to write the SD Card infrequently.
The monitoring device 30 is configured to analyze an operation parameter of the equipment load, determine an abnormal point according to the operation parameter, and provide a maintenance suggestion. For example, through a database and a corresponding algorithm, the received operation parameters are decoded and analyzed, and are compared with local standard data in a difference mode to obtain a difference item, common causes of abnormal faults are given, maintenance suggestions for solving guidance are provided, and maintenance personnel can more quickly and effectively give a solution according to the maintenance suggestions, so that the fault problem is fundamentally solved, secondary maintenance is reduced, and after-sale cost is reduced. In some embodiments, the monitoring device 30 may be a computer device carried by an upper computer of the local equipment or a maintenance person.
In some embodiments of the present invention, the master control device 10 is configured to occupy the data bits of the communication transmission data frame in order to perform encoding compression according to the required data occupancy length of the operating parameter of the load. Specifically, data transmission is in the form of "1" and "0", and one communication transmission data frame includes a plurality of bytes, and one byte includes 8 binary data bits. For example, if the operating state of a certain load a has four states, two data bits are required to represent, and the operating state of another load B requires four data bits to represent, when performing encoding compression, the first two data bits of a communication transmission data frame may represent the operating state of the load a, the third to sixth data bits may represent the operating state of the load B sequentially, and so on, and occupy one communication transmission data frame, and the space size of the communication transmission data frame may be fully utilized to implement encoding compression. The priority of data bit occupation of the communication transmission data frame can be set according to the importance degree of the operating parameters of the load, that is, the data bits of the communication transmission data frame can be occupied in sequence according to the importance degree of the operating parameters, and the more important operating parameters preferentially occupy the data bits in front of the communication transmission data frame. Thus, the read/write speed of the storage device 20 can be increased, and the data can be transmitted at the same time, and the operation parameters of the key load of the equipment can be included.
Next, the encoding compression will be described by taking a refrigerator as an example. The main control device 10 and the storage device 20 communicate through an SPI, and the communication transmission data frame includes 6 bytes, and in some embodiments, the 6 bytes include at least one of a time bit, a fan status bit, a compressor status bit, a valve indication bit, a damper status bit, a heater status bit, an ice maker status bit, and an indicator light status bit.
In some embodiments of the present invention, the master control device 10 performs coding compression on the operation parameters according to the required data footprint of the operation parameters of the load, and includes at least one of the following: taking four bits of data in the length of a communication data frame as a month; taking five bits of data in the length of the communication data frame as the current month date; taking at least one bit of data in the length of the communication data frame as the state of the fan; taking at least one bit of data in the length of the communication data frame as the state of the compressor; taking five bits of data in the length of a communication data frame as valve direction; taking four-bit data in the length of a communication data frame as the state of a throttle; taking one bit of data in the length of a communication data frame as a heater state; taking one bit of data in the length of the communication data frame as the state of the ice machine; taking one bit of data in the length of a communication data frame as an indicator light state; taking four-bit data in the length of a communication data frame as a mainboard version number; and taking four bits of data in the length of the communication data frame as the version number of the display panel. Of course, the more critical operating parameters of the load may be selected according to specific equipment and specific situations, and the data bits of the communication transmission data frame may be occupied by priority to perform encoding compression, and the representation of the specific data bits of the communication transmission data frame is not particularly limited herein.
By way of example, FIG. 2 is a diagram illustrating an encoding compression scheme according to an embodiment of the present invention, and SPI communication scheme is capable of transmitting only 6 bytes, e.g., the first byte 1, for a framestbyte, second byte 2ndbyte, third byte 3rdbyte, fourth byte 4thbyte, fifth byte 5thbyte and sixth byte 6thbyte, which is 48 bits of data, as shown in fig. 2, gives the operating parameters expressed in cis for the 6 bytes of 48 bits of data in this embodiment.
Specifically, for example, the time bits include a month data bit and a current month date bit, and the month data is expressed as: 0000 represents month 1, 0001 represents month 2, and so on, and 1100 represents month 12, and thus, the month data requires four data bit lengths, as shown in fig. 2; the daily data are expressed as: 00000 represents the number of the current month 1, 00001 represents the number of the current month 2, and so on, and 11111 represents the number of the current month 31, and therefore, the date data requires five data bit lengths.
For another example, the fan includes a fan 1, a fan 2, a fan 3, and a fan 4, and the state of the fan 1 is represented as: 00 represents an uncontrollable fan which is closed currently, 01 represents an adjustable fan which is opened currently, 10 represents an adjustable fan which is closed currently, 11 represents an adjustable fan which is opened currently, the current states of the fan 2, the fan 3 and the fan 4 all represent that the fan is opened by 1, and 0 represents a fan switch. The state of the compressor is represented as: 1 denotes compressor on and 0 denotes compressor off. The valve pointing state is represented as: the highest position 1 of the valve represents a health source valve, 0 represents a three-flower valve, X0000 represents resetting, X0001 represents no action, X0010 represents refrigeration, X0011 represents refrigeration, X0100 represents temperature change, and X0101 represents refrigeration. The damper status can be represented by four digits, with the highest position 1 representing a single damper, 0 representing a double damper, X000 representing a damper closed, X001 representing a damper open to cold, X010 representing a damper open to cold, and X011 representing a damper open at reset. The heater status, the ice maker status, the status light 1 status, the status light 2 status, the status light 3 status, and the status light 4 status may all be represented by one bit, for example, a data bit of 1 represents on, and a data bit of 0 represents off.
In some embodiments of the present invention, as shown in fig. 2, the communication transmission data frame further includes a check bit, which can be checked in a checksum manner, the master control device 10 compares the sum of the data of the corresponding bits of the first five bytes in the length of the communication data frame with a pre-stored standard value of the corresponding bit of the sixth byte to check whether the communication data is correct, if the sum of the data of the corresponding bits of the first five bytes is consistent with the standard value of the corresponding bit of the sixth byte, the communication data is considered to be correct, otherwise, the communication data is incorrect.
In an embodiment of the present invention, as shown in fig. 3, the after-sales monitoring system 100 of the apparatus according to the embodiment of the present invention may further include a display and control device 40, where the display and control device 40 is connected to the main control device 10, and is configured to receive a user instruction to send an acquisition instruction of an operation parameter of a load. As shown in fig. 4, which is a schematic view of a monitoring interface of a display control device according to an embodiment of the present invention, the display control device 40 may provide the monitoring interface, for example, the monitoring interface includes a triggering unit such as a freezing fan analysis, a refrigerating fan analysis, a compressor analysis, a defrosting heater analysis, a refrigerating door analysis, a freezing door analysis, a refrigerating chamber temperature analysis, and a freezing chamber temperature analysis. When an after-sales person needs to read the current instantaneous state of the refrigerator, the monitoring device 30 can send an instruction to the main control device 10 by operating a trigger unit of the monitoring interface, such as a combination key, and the main control device 10 immediately writes the current operating parameters of the load into the storage device 20, such as an SD card. When after-sales personnel need to read the running state parameters of the refrigerator, the SD card can be directly taken down and connected with the monitoring device 30 through a card reader, or the monitoring device 30 is connected with the storage device 20 and directly reads the stored data, and through the monitoring device 30, the after-sales personnel can check the previous historical data and the current data, check the analysis performed through big data, give a solution and complete fault maintenance quickly and efficiently.
In some embodiments, fig. 5 shows that the after-market monitoring system 100 of the equipment according to the embodiment of the present invention may further include a research and development analysis device 50, where the research and development analysis device 50 is configured to obtain the operating parameters and the abnormal point information of the load. As shown in fig. 5, the main control device 10 includes, for example, a main control board peripheral circuit and a minimum system of a single chip microcomputer, encodes and compresses the operating parameters of the load and transmits the encoded and compressed operating parameters to the storage device 20, such as an SD card, the monitoring device 30 decodes the stored operating parameters, analyzes and judges abnormal points of the operating parameters, provides maintenance suggestions, and after-sales personnel obtain the maintenance suggestions through the monitoring device 30 and provide solutions, so that the failure can be quickly and effectively eliminated, the failure problem can be fundamentally solved, secondary complaints of users can be avoided, and the after-sales cost can be reduced. Meanwhile, the monitoring device 30 can also automatically upload the operation parameters and the fault point information to the research and development analysis device 50, so that research and development personnel can further judge whether the equipment design defect is included, thereby improving the equipment design defect.
In summary, the after-sales monitoring system 100 of the present invention can help the after-sales personnel to analyze the failure of the device conveniently and quickly, and provide a fundamental solution, and at the same time, can provide data support for research and development so as to improve the design of the next generation product.
