Description

[0001] WIRELESS TEMPERATURE DIAGNOSIS APPARATUS [0002]

The present invention relates to a wireless temperature sensing device, and more particularly, to a wireless temperature sensing device having a magnetic flux concentrator at both ends of a core to maximize the flux amount and to efficiently generate electric power using the same, To a wireless temperature sensing device using a magnetic energy harvesting coil capable of easily measuring the temperature of an object.

In general, plants, heavy industrial plants, subways, oil complexes, chemical complexes, steel mills, etc. are equipped with a power transmission and distribution panel that distributes power to the unit power sources that can be used in various power devices while controlling the main power source provided by KEPCO.

Such a switchboard is usually provided on the front surface of the base panel and includes at least one main breaker for controlling the main power and a plurality of sub-circuit breakers for controlling the unit power.

The main breaker and the sub circuit breaker are electrically connected and connected to each other by at least one main bus bar and a plurality of sub bus bars which provide a line for distributing the main power to the unit power source.

As described above, since the booth bar including the main bus bar and the sub bus bar is formed in the form of a metal plate, the heat dissipation is excellent because the surface area is wide, and the heat generation amount due to the impedance reduction is reduced. Thus, the line for distributing the main power into the unit power source And to provide it stably.

Here, the amount of current flowing through the bus bar changes depending on the load variation of the power device using the unit power source at the customer side. If the amount of current increases or the load current excessively acts, the temperature of the bus bar increases.

The temperature rise of these bus bars will have a significant impact on the stability of the power supply system and should be monitored.

Conventional temperature measurement uses an infrared temperature sensor or a thermal imaging camera as a non-contact type, and a thermistor or the like is used as a contact type.

Since contactless sensors can be observed only within a visible range, there is a problem that electric accidents due to deterioration in a dead zone can not be prevented in advance, and a contact type is being developed.

In the case of a contact type sensor, there is a problem in that a large factory requiring a lot of booth bars in a streamline type and a wireless type requires a lot of temperature sensors to be installed in a desired bus bar and requires wiring work for power supply and communication, .

In case of wireless type, separate power source such as dry battery or battery is required for each module in order to supply power to temperature sensor and transmission / reception module. Therefore, battery or battery should be replaced periodically. Especially, Or the battery power needs to be changed.

On the other hand, in addition to the above-described bus bar, the current flowing through the outdoor transformer terminal, the bus duct, the transmission line, the cable tray, and the underground cable increases in the amount of electric current or the load current becomes excessive.

This temperature rise should be monitored as it causes damage to the power equipment and causes a fire or the like to seriously affect the stability.

Since such electric power facilities are installed in complicated places or in places where people are difficult to access, there is a problem in that a large number of temperature sensors are required to be installed in desired facilities, and wiring work for power supply and communication is required, which is troublesome and takes a long time.

In addition, as described above, in the case of the wireless type, independent power source such as dry battery or battery is required for each module in order to supply power to the temperature sensor and the transmission / reception module. Therefore, it is necessary to replace the battery or battery periodically, There is a problem that the battery or the battery power must be changed after power failure.

In order to solve such a problem, a device for measuring the temperature by radio by converting magnetic energy into electric energy using a coil has been developed.

However, in order to measure the temperature of a power line in which a small current flows, the core must be enlarged in order to collect a large amount of magnetic flux around the core, and a plurality of cores must be connected in series in case of power shortage. .

Generally, the core shape of the energy hubbing coil is a cylindrical structure. In this case, the focusing performance of the leakage magnetic flux is lowered and the generated power is weakened, so that it is difficult to drive the temperature sensing device through self-power generation.

Therefore, a method for solving such problems is required.

An input / output unit outputting data processed by the second control unit, receiving a command from a user, and a display unit outputting data converted by the second control unit to the outside; And
And an alarm unit for generating an alarm sound when the temperature of the object measured by the temperature sensing module exceeds a temperature reference preset by a user,
Wherein the first temperature sensor part has a probe protruding out of the housing at least partly in contact with the object and measuring the temperature,
Wherein the clamp unit provided on the outer surface of the housing has a bent shape and detachably couples the housing to the object in a form of wrapping at least a part of the object,
Wherein the probe is protruded outside the housing in a direction in which the clamp unit protrudes,
The receiving module may further include a second temperature sensor unit for measuring an external environment temperature of the receiving module,
Wherein the first temperature sensor unit compares and analyzes the temperature of the external environment measured by the second temperature sensor unit with the temperature of the object measured by the first temperature sensor unit to diagnose the heating state of the object,
A plurality of temperature sensing modules are provided, each temperature sensing module has a respective individual ID,
The first communication unit receives the ID of the temperature sensing module to receive data and the data format to be transmitted from the monitoring module and the first control unit may transmit data corresponding to each of the selected temperature sensing module IDs to the monitoring module Convert the data,
Wherein the display unit is divided into a plurality of zones so that temperatures measured by the plurality of temperature sensing modules are respectively displayed. delete delete delete delete delete delete delete delete delete
