These sintered ores, coke and additives are charged in a fixed form from the upper part of the blast furnace to the multi-stage, and hot wind is blown through the lower tuyeres to burn the cottons and produce sludge by reducing the sintered ores.

In the upper part of the blast furnace, the sintered light and the coke are charged one by one, and the bottom is melted and the charge is totally lowered. The inside of the blast furnace is divided not only in the vertical direction but also in the radial direction, so that the temperature change and the charge falling speed are different.

In order to stabilize and manage the furnace lime, three dimensional monitoring is required for the distribution of temperature inside the blast furnace and the state of charge drop, so a measuring device is required. In addition, although the quality of coke and sintered ore has a great effect on the agar content, it takes several hours to measure the quality of the raw material, so it is necessary to perform position tracking and predictive agglomeration Do. That is, it is necessary to predict the fluctuation of sulfur content by the raw material by tracking the location and quality of the raw material from the coke / sinter plant to the inside of the blast furnace.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order that those skilled in the art can easily carry out the present invention.

1 is a schematic block diagram of a wireless sensor node according to an embodiment of the present invention, a raw material tracking apparatus using the same, and an apparatus for measuring an in-furnace furnace using the same.

1, a wireless sensor node, a raw material tracking apparatus using the same, and a blast furnace measurement apparatus using the same include an IoT (internet of things) wireless sensor having a unique ID (Identification Identification Number) A node 100, a wireless transceiver 220 for receiving ID, location and measurement values from a wireless sensor node, an ID, position and metering value from the wireless transceiver 220 for tracking, And a collection and analysis unit (230, 330) for receiving the quality information of the raw material and determining the overall location of the raw material, the quality, and the situation in the blast furnace.

The wireless sensor node 100 according to an embodiment of the present invention is inserted into the raw material conveyed through the belt conveyor of the raw material tracking apparatus 200 to track the transportation of the raw material or to measure And may be injected into the blast furnace 310 to participate in the lamination profiling information of the raw material.

First, when the raw material tracking device 200 is loaded in a belt conveyor in a sintering process and a coke process, the wireless sensor node 100 is inserted into the front end and the rear end of the raw material. The position of the raw material is tracked by grasping the position of the line / rear end through the wireless transceiver 220 installed in the belt conveyor.

The quality analyzer 210 records the ID information of the wireless sensor node 100 inserted into the raw material when the sample is taken for measuring the quality of the raw material, and collects and transmits the ID information and the quality information together after the quality analysis do.

The quality analysis unit 210 analyzes the quality of the raw material by taking samples from the sintering process and the coke process. At this time, the ID of the sample is matched with the ID of the wireless sensor node 100, and the bin and the quality information of the raw material charged in the blast furnace 310 are associated with each other. Also, in the case of coke, profile information is provided wherever the yard comes from within the coke bin, and it can be known when it is put into the blast furnace. In addition, the quality information includes cold strength, hot strength, and components, and it is possible to respond to the blast furnace operation preliminarily according to the quality of the raw material supplied to the blast furnace.

When the sintered light bin and the coke are stacked in the sintered light bin and the coke bins, the wireless sensor nodes 100 form a self network to transmit the location of the lower sensor node to the upper sensor node, and the wireless transceiver 220 ) And transmits the information to the collection and analysis unit. The collection and analysis department creates profile information on the level of the raw material put into Bin. Additional sensor nodes can be added with the raw material to measure the detailed profile. The wireless sensor node 100 measures a position using a gyro sensor and an acceleration sensor on the basis of a position of a time when the sensor node 100 is inserted into a bin and transmits the measured position to another wireless sensor node to transmit information through a wireless transceiver 220).

In the furnace measurement device 300, the raw material discharged from the bin is charged into the blast furnace, which is similar to the case when it is stacked on the bin. The location is measured using the gyro sensor and the acceleration sensor based on the loading time point and transmitted to another node to transmit information to the wireless transceiver 220 through multi-hop communication. The information conveyed includes temperature information that is measured while descending in the blast furnace along with the charge.

The blast furnace operation needs to determine the falling speed of the raw materials (sinter ore, coke) charged in order to maintain the aging stability and to improve the productivity of the molten iron (cinder) and the temperature distribution inside the blast furnace.

Also, in order to stably supply the charge, the level of the sintered-metal bin and the coke breeze must be kept constant. In the case of coke, the coke for charging the quality of the coke oven outside the yard is charged into the coke breeze. Operational conditions should be set in advance. To do this, you need to know the source-specific profile of where the raw materials are coming from within the bin.

In addition to yard coke, quality information of all raw materials should be linked to determine the influence of blast furnace sulfur in advance.

In the bin and the blast furnace 310, since the arrival distance of the radio signal is short because it is laminated with iron ore (sintered ore) and coke (coking coal), the radio signal can not be directly transmitted to the external radio transceiver. Accordingly, the ad-hoc network between the wireless sensor nodes 100 is dynamically formed, and the sensor nodes located under the blast or bin relay data to the upper wireless transceiver 320 while transmitting data to the adjacent sensor nodes. The data of the wireless signal includes the ID, temperature, coordinates, and the like of the wireless sensor node.

The collecting and analyzing unit 330 tracks the position of the raw material using the ID of the wireless sensor node 100 inserted together with the sintered ores and the coke and records the profile information accumulated by the source of the raw material in the coke bins and the coke bins . For example, in the case of coke, it can be estimated whether the coke charged in the bin or the blast furnace came from a coke process or a coke loaded in the yard. In addition, the position of the wireless sensor node 100 can be received in real time, and the position of the wireless sensor node 100 can be grasped in the Bin and the blast furnace, and the descending speed of the charge can be measured and analyzed in three dimensions in the blast furnace. Also, the temperature profile in the blast furnace can be analyzed in three dimensions using the received temperature value.

2A and 2B are an internal configuration view and a plan view of a wireless sensor node according to an exemplary embodiment of the present invention.

Referring to FIG. 2B, the wireless sensor node 100 has an outer shape similar to an aspherical body and an ellipse so as not to be rolled from the bulk of the raw material during transportation of the belt conveyor, and is not broken in the belt conveyor, It has the strength to withstand the lamination load of the charge and can withstand the temperature in the blast furnace.

The wireless sensor node 100 has a strength that can overcome the impact and the load-carrying capacity of the belt conveyor during transport, and is made of a material outer shell that can overcome the temperature of the blast furnace. On the inner surface, a heat- Delay the temperature rise for a period of time. After a certain period of time, the wireless sensor node is melted.

That is, it falls down with the charge in the blast furnace, and when it reaches a certain temperature or more, it melts together with the molten material and disappears.

The sensor node case 100a must maintain heat resistance at a high temperature and maintain a high temperature strength for a short time. Using a forging alloy of nickel group, it is ensured to the temperature of 800 ° C and melted near the fusion zone. Such a wireless sensor node does not affect solubility.

The sensor node inner plate 101 delays the transfer of the temperature in the blast furnace into the sensor node using a heat resistant material having a low conductivity. For example, since the raw material charged in the blast furnace is lowered and melted down to a lower level over a certain period of time, the internal temperature rise is delayed by using a heat resistant material so that the life of the sensor node can be maintained within several hours.

3 is a block diagram of a wireless sensor node according to an embodiment of the present invention.

2A and FIG. 3, a wireless sensor node 100 according to an exemplary embodiment of the present invention includes a transmission / reception antenna 104, a wireless signal processing unit 105, sensor units 102, 107 and 108, 103, and 109, and a control unit 110, and may further include an ID storage unit 106. The sensor units 102, 107 and 108 may include a temperature sensor 102, a gyro sensor 107 and an acceleration sensor 108. The measurement units 103 and 109 may include a temperature measurement unit 103, (109). ≪ / RTI > The position measuring unit 109 calculates the position based on the blasting time using the gyro sensor 107 and the acceleration sensor 108 and calculates the position using the intensity of the wireless signal received from the upper node.

The wireless sensor node 100 arranges the transmitting / receiving antenna 104 on six sides so as to transmit / receive wireless signals in any direction. The transceiving antenna 104 may be a directional antenna.

Two temperature sensors 102 of the wireless sensor node 100 may be installed at opposite positions so that the temperature of the gas flow piece coming from the lower portion of the wireless sensor node 100 can be measured even if the wireless sensor node 100 is located in any direction. In addition, the wireless sensor node 100 can be used as a spare in preparation for the breakage of one side.

The environment in which iron ore (sintered ores) are piled up is a propagation environment in which the magnetic field prevails due to distortion and attenuation of electromagnetic waves due to iron components, so that a helical structure antenna can be used. 2A, the antennas are arranged in four directions so that the radio waves can be transmitted to the sensor nodes in the upper part regardless of the directions of the wireless sensor nodes.

Starting from the reference position, the gyro sensor 107 measures the direction and the acceleration sensor 108 measures the moving distance in real time when charged into a bin or blast furnace for position measurement of the wireless sensor node, Accurately measure the position of the sensor node. The wireless signal processing unit 105 measures the strength of a wireless signal received from another wireless sensor node and estimates the distance to another node from the strength. By estimating the distance from at least three different nodes, the position of the wireless sensor node can be measured by the triangulation method. Each wireless sensor node also includes its own location information when transmitting the measured values to the wireless signal. The wireless sensor node receiving the wireless signal uses the strength of the received wireless signal and the coordinates of the wireless sensor node that sent the wireless signal.

FIG. 4A is a block diagram of a transmitting / receiving antenna of a wireless sensor node according to an embodiment of the present invention, and FIG. 4B is a diagram illustrating a transmitting / receiving antenna arrangement of a wireless sensor node according to an embodiment of the present invention.

Referring to FIG. 4A, the environment in which iron ore (sintered ores) are piled up is a propagation environment in which a magnetic field prevails due to distortion and attenuation of electromagnetic waves due to iron components, so that the transmission and reception antenna 104 may include a helical antenna 130 . The helical antenna 130 may be formed in various shapes including a circular shape, an elliptical shape, a triangular shape, and a rectangular shape. The winding (number of turns) of the conductor is determined by the impedance of the antenna input circuit of the sensor node.

The transmission / reception antenna 104 disposes the metal plate 131 between the helical antenna 130 and the matching portion 132 in order to prevent radio signal interference by the antenna in the opposite direction. The metal plate 131 prevents the radio waves from being transmitted to the sensor node or the opposite antenna.

Eddy current is induced on the surface of the metal plate 131 to form a magnetic field in a direction opposite to that of the signal radiated by the antenna, thereby interfering with the antenna, and therefore, the intermediate layer 133 is disposed. The intermediate layer is formed by stacking the silicon steel sheets one by one, or by using a high permeability ferrite to suppress eddy currents.

It is necessary to prevent the signal received via the antenna from being reflected by the impedance difference between the antenna and the signal line. Therefore, impedance matching is adjusted in the matching section 132 in consideration of the impedance change under various conditions. The helical antenna may have a dipole structure in order to reduce the abrupt change of the input impedance depending on the input impedance of the metal plate or the laminated iron ore shape.

Referring to FIG. 4B, the transmitting and receiving antennas 104 are disposed in four directions on a cross section like a wireless sensor node according to an embodiment of the present invention. Even if the sensor node is located in any direction, . For example, the transmitting and receiving antenna 104 can be disposed at 0 degree, 90 degrees, 180 degrees, and 270 degrees.

5 is a network configuration diagram of an apparatus for measuring a burnt furnace in accordance with an embodiment of the present invention.

Referring to FIG. 5, the wireless sensor nodes 100 constitute a self network. Since the wireless signal transmission distance between the sintered light and the coke is within a few meters, the nodes themselves form a network, and the node transmits a radio signal to the immediately adjacent upper node so that the ID and measurement values can be transmitted to the wireless transceiver 220 installed in the blast furnace. have. For this purpose, each sensor node receives a signal from a lower node and transmits it to the upper node. The IDs and measurement values of the wireless sensor nodes 100 collected in the wireless transceiver 220 may be transmitted to the collection and analysis unit 330.

As described above, according to the present invention, the location and quality of the raw materials charged in the blast furnace are tracked to determine the influence on the aging, and the aging can be stably maintained by setting the operating conditions in advance. In addition, by measuring the level profile of the raw material bin, it is possible to maintain the raw material level at a certain level at all times, thereby stably supplying the raw material to the blast furnace.

In addition, it is possible to accurately measure the descending speed and temperature of the charge by internal location of the blast furnace, and it is possible to judge the situation inside the furnace by means of which it is possible to respond to the blast furnace in proper time in real time, stabilize the aging and operation, .
