Automatic diagnosis and data monitoring system for commercial dish-washing machine

Abstract

The embodiment of the invention provides an automatic diagnosis and data monitoring system for a commercial dish-washing machine, the system comprises a sensor, a dish-washing machine main control board, a network communication module, a server, a maintenance processing unit, a data analysis unit and a program design unit; the dish-washing machine main control board is placed inside the commercialdish-washing machine and connected with the server through the network communication module, collects operating data acquired by the sensor and performs preprocessing to obtain fault information, andsends the operating data and the fault information to the server through the network communication module; after judging a fault type, the server sends information to the maintenance processing unitto process, when the server cannot judge the fault type, the server sends the information to the data analysis unit to process, a new fault diagnosis algorithm is compiled according to a processing result through the program design unit, and the dish-washing machine main control board is updated with the fault diagnosis algorithm through the network communication module. The system provided by theinvention can automatically diagnose, monitor and predict various faults and improper operations of the commercial dish-washing machine.

Description

technical field [0001] The invention relates to the technical field of dishwasher automatic control, in particular to an automatic diagnosis and data monitoring system for commercial dishwashers. Background technique [0002] Dishwasher is a device used to automatically clean tableware such as bowls, chopsticks, plates, plates, knives, forks, etc. It reduces labor intensity, improves work efficiency, and improves cleaning health. [0003] Dishwashers are divided into commercial dishwashers and household dishwashers according to their uses. Among them, commercial dishwashers are suitable for commercial purposes, mainly used in hotels, restaurants, restaurants, etc., and are characterized by high temperature, high strength and short-term processing. [0004] Commercial dishwashers are composed of multiple components, which can be roughly divided into the following six systems in addition to the basic mechanical structure (such as structural frame, main wash water tank, and ri...

AI Technical Summary

Problems solved by technology

This kind of dishwasher does not have the ability of automatic fault diagnosis and data monitoring

[0012] The second is the current mainstream technology, which uses a single-chip microcomputer for control, but this technology is not connected to the Internet or even though it is connected to the Internet, it can only upload the number of cleaning boxes, but not all the sensors and operating data of the dishwasher.

It is not possible to determine very complex problems through data analysis, such as the damage of one of the three circuits of the rinsing heating pipe

[0014] (2) The ability to accurately determine the fault is limited, especially it cannot be judged whether the sensor has a problem or the sensor monitoring system has a problem

For example, if the temperature of the rinse water tank does not rise for a long time, this solution cannot determine whether there is a problem with the heating pipe or the temperature sensor.

[0015] (3) It is impossible to predict failures in advance according to changes in equipment operating status

[0016] (4) The error code can only be displayed on the display screen, but the user or the maintainer cannot be directly informed of the specific fault.

[0017] (5) Maintenance personnel cannot analyze the cause of the failure by analyzing the data of the dishwasher

[0018] (6) Unable to upgrade online, and the fault diagnosis code written at the factory cannot be updated

[0019] (7) It cannot be judged whether it is used properly by monitoring data

However, when this automatic diagnosis control system is not working properly in commercial dishwashers, it is difficult for maintenance personnel and operators to find out; it is also difficult for operators to detect and correct improper operations; Accurately determine where the fault lies
