Embodiment Construction

[0019] The following is based on figure 1 , figure 2 and image 3 A preferred embodiment of the present invention is given and described in detail, so that the structural features, functions and characteristics of the present invention can be better understood.

[0020] see figure 1 and figure 2 , as shown in the figure, the temperature detection system of the coke oven oven in this embodiment includes a precision grade K-type thermocouple 1, an IAS temperature measurement module 2, an RS 232 / 485 converter 3, a server machine 4, and a client machine connected in sequence 5. According to the requirements of the oven, 307 temperature detection points are arranged, and a precision K-type thermocouple is set at each temperature measurement point, and every 4 to 7 precision K-type thermocouples are connected with an IAS temperature measurement module 2 . The IAS temperature measurement module 2 undergoes sampling processing to correct the temperature detected by the precisio...

Abstract

The system includes a numbers of precision thermocouples to be set in several groups, each group connected to a thermometric module which is connected with convertor and server is sequence as thermometric control program to be set in the server. The thermometric step is as follows: selecting thermometric points in coke-oven, setting a precision thermocouple on each point, grouping thermocouples and connecting a thermometric module to each group, carrying on addition and correction for cold end of precision thermocouple by thermometric module, issuing collecting instruction by the server at fixed interval time, converting the added and corrected temperature to be data through the convertor as the data stored in data bank.

Description

technical field [0001] The invention relates to temperature detection, in particular to the temperature detection of a coke oven oven. Background technique [0002] Before the new coke oven is put into production, it must go through about 80 to 90 days of oven drying process, and the coke oven body is heated from normal temperature to above 1000 ℃, and then it can be officially put into production. Usually, more than 300 temperature measuring points must be set for baking a coke oven. Accurately detecting the real-time temperature of these measuring points is the basic guarantee for controlling the heating rate strictly according to the plan. [0003] The traditional furnace temperature detection method is as follows: [0004] Due to the slow rate of temperature rise in the low temperature stage, the daily temperature rise is only 3°C in some time, the ambient temperature change of the cold end of the thermocouple is greater than the change of the temperature of the hot en...
