Description

  The present invention relates to a method for measuring the flue temperature of a coke oven.

  In order to optimally maintain the quality and productivity of coke produced in a coke oven at an ironworks, it is important to properly manage the flue temperature distribution in the coke oven. Also, from the viewpoint of extending the life of the coke oven body, it is important to properly manage the flue temperature distribution of the coke oven.

  In order to properly manage the flue temperature distribution of the coke oven, it is necessary to accurately measure and record the flue temperature of 1000 to 4000 locations per furnace group in a high temperature coke oven. Furthermore, when making a database of the measured values of the coke oven flue temperature, it is also required not to cause a recording error or registration omission.

However, in addition to the infinite number of flue measurement patterns for coke ovens, traditionally, flue temperature measurement work has been performed in groups of multiple people, including temperature measurers, data recorders, and preparatory workers. The person who communicated verbally to the data recorder, and the temperature measurement data recorded by the data recorder on-site by hand, was input to the coke oven management server in a database, and was performed through multiple processes by multiple persons. There has been a problem that an artificial measurement error due to a recording error or the like is likely to occur.

  In addition, when an analog thermometer is used, there is a problem that an artificial error occurs in the temperature reading value and a series of data processing operations including a data input operation take a long time.

  As a technique for solving the problem of measurement errors and recording errors based on these artificial factors and the problem that it takes an enormous amount of time for data processing work, for example, Patent Document 1 discloses that measurement data from a measurement means is directly stored in a recording means. An input data aggregation device is disclosed. Furthermore, in Patent Document 1, as a technique for avoiding an artificial measurement error due to measurement omission, when a measurement person touches a measurement mode selection screen displayed on the recording unit, it is stored in advance in the memory of the recording unit. It is described that the order of performing the furnace temperature measurement is determined based on the basic measurement pattern and displayed on the recording means, and the measurement operator performs the measurement according to the display.

  However, in the method of Patent Document 1, since the flue temperature measurement pattern is bound to the basic measurement pattern stored in the memory in advance, the flue temperature measurement location and the temperature measurement order can be freely changed as necessary at the work site. There was a problem that work efficiency was bad. In addition, since the temperature measurer's hand is blocked by the temperature measuring means, there is a problem that it is not easy to work while visually confirming the measurement location displayed on the display screen of the recording means.

  The inefficiency in work efficiency and workability in coke oven flue temperature measurement work was discovered from the temperature measurement, and problems related to the flue temperature distribution were discovered based on the temperature measurement data, and the flue temperature distribution was adjusted to be within the control standard range. This is a factor that causes a time lag before the management action is taken, and is not preferable from the viewpoint of appropriate management of the temperature distribution.

It was. However, the form of this interface is insufficient to establish a full temperature measurement operation with a large number of measurement points as an efficient and accurate single operation. Therefore, in addition to the conventional manual input, voice input is used in combination for information transmission to the devices. In addition, a method in which manually input and voice input data is automatically transferred to the portable information processing terminal.

  FIG. 2 shows a block diagram for explaining the system configuration of the present invention, and FIG. 3 shows a basic flowchart of the system of the present invention. Hereinafter, according to each step shown in FIG. 3, the present invention will be described with reference to FIG.

(First step)
In the first step, the coke oven temperature measurement operator 1 accesses the flue designation guidance data 31a stored in the PDA terminal 3 before the temperature measurement operation is started. The flue designation guidance data 31a is stored as electronic data, but is transferred to the voice input / output device 2 and converted into voice data by the voice-to-electronic data conversion automatic conversion means 23. Output as data. In order to sequentially input each element of measurement method, furnace number, start column position, start column position, measurement column interval, and measurement direction, for example, as indicated by “audio output A” in FIG. Information is stored for guidance.

In the second step, the coke oven temperature measurement worker 1 inputs the response content from the voice input / output device 2 so as to respond to the voice data output in the first step. The voice input data is converted into electronic data by the voice-electronic data conversion automatic conversion means 23 and then stored as the flue designation data 31c in the input data storage area in the PDA terminal.

  By repeatedly performing the first step and the second step, the flue designation data 31a can be input in a conversational format. The newly stored flue designation data 31c is output as a sound. This prompts confirmation of the input person and guarantees the accuracy of the work. After the confirmation, the first step and the second step are repeated again to define each element of the measurement method, furnace number, start train position, start flue position, measurement interval, and measurement direction. In general, since it reaches 1000 to 4000 locations per coke oven in the coke oven, it is easy to cause human error such as omission of measurement of the flue to be measured and wrong order. As a countermeasure, for example, a predetermined basic measurement pattern In the case of performing measurement at the work site, the flue temperature measurement location and the temperature measurement order cannot be freely changed as necessary at the work site, resulting in a new problem that the work efficiency is deteriorated. In order to solve this problem, in the present invention, by specifying the measurement flue by each of the above-mentioned elements, even in the coke oven, about 1000 to 4000 flues per one furnace group are measured artificially such as measurement omission and wrong order.
