Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea factory management means, and particularly to grasp the operation status of a tea factory at a sales office or the like to optimize the operation of each tea manufacturing apparatus in the tea factory, The present invention relates to a tea factory network management system that enables a person concerned to promptly and efficiently deal with a failure.

[0002]

BACKGROUND OF THE INVENTION In a tea factory, the busiest period of the year is generally from the beginning of April, which is the tea season, to the end of October. The operating rate of is significantly reduced (the average number of operating days per year is about 40 to 50 days). From such a long idle state, it will enter the full operation of the busiest year, the highest product price, and the most demanded tea season (so-called new tea season), so initially there will be problems with tea making equipment It's easy to do. For this reason, although trial operation is performed in advance at each tea factory, it is not possible to reproduce high load under full operating condition, and even if the processor side and the tea making machine side pay close attention, no trouble will occur. The reality is that it cannot be avoided.

If the factory is once shut down due to some trouble as described above, processing delay and deterioration of rough tea quality are caused. Another factor is the temperature difference in one day,
The optimum setting value of each tea making device may change due to environmental conditions such as humidity difference, and if the optimum setting value cannot be corrected, the quality of rough tea is deteriorated, resulting in a large decrease in revenue.

In the busy season, troubles are likely to occur in a plurality of tea factories, and a tea machine maker responsible for maintenance of tea making equipment is required to respond 24 hours a day. More people must be deployed during the period than usual.

By the way, recently, a LAN including individual tea-making equipment in each tea-making factory has been constructed, and a network connecting these with a sales office or head office established by the tea-making machine manufacturer in each region is constructed. Attempts are being made to monitor tea factories and operate tea making equipment.
However, even if such a network is used, the information about the tea-making equipment sent to the base is the numerical data that is the detection value of various sensors and the voice of the operator of the tea-making factory, and the application of the network is the remote control. Stays in. Further, although it is possible to discriminate the defective part and the defective part by using such a network, it is extremely difficult to identify the defective part and determine the necessity of the parts replacement related to the handling practice.

Further, the tea making process has been mechanized over almost the whole area these days, and although a series of processing can be performed according to a standard tea making program, the judgment of the characteristics of the processed tea leaves is still based on the experience of the operator. There is also a part to rely on (for example, when checking the steaming condition, visually check the steamed leaves, touch them with your hands, and smell them to judge whether they are good or bad)
When there is an abnormality in the properties of the processed tea leaves, it is difficult for a representative of the sales office to determine the properties of the processed tea leaves, for example, at a place away from the tea factory only by the information on the quality detected by various sensors.

[0007] According to the data sent to the base there,
When it is determined that the host computer has a problem, or when the tea factory reports that a problem has occurred, a representative of the sales office goes to the tea factory. Then, for the first time in the field, the failure point, failed parts, failure condition, necessity of parts replacement, etc. are clarified, and it is possible to move on to the work for restoration. Especially when parts replacement is necessary, return to the base to get parts Or, another person who was instructed had to bring parts from the base, or had to bring many kinds of parts when visiting. Under such circumstances, especially during the first tea season (busy season), labor is insufficient. Therefore, it is desired to develop a management means of a tea factory capable of swiftly and efficiently dealing with troubles.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and makes it possible to optimize the operation of each tea making machine in a tea factory and to operate each tea making machine without delay.

[First Embodiment] First, an operation example of the tea factory network management system 1 using information about a failure, information about a tea factory, information about a repair, and movement information will be described. When a mechanical failure occurs in any of the tea making devices in the tea making line 10, the control panel determines the detected value of the sensor included in the tea making device as an abnormal value (abnormal sound, abnormal vibration, etc.). The abnormal value, which is information related to this failure, is transmitted to the centralized control panel 20 via the trunk line 8M, and further transmitted to the sales office 3 and the head office 2 via the backbone 5.

The centralized control panel 20, the computer 7 and the host computer 6 specify the tea making apparatus from the source of the information regarding the failure. (The failure information and the tea making device information may be transmitted at the same time.) Then, by referring to the information about the tea making factory, the model number, year, etc. of the broken tea making device are determined. Then, by referring to the repair history, which is the information about the repair, the past failure site is searched, and the information is displayed on the display provided in the centralized control panel 20.
