It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. , ≪ / RTI > equivalents, and alternatives.

FIG. 1 is an overall configuration diagram of an active thermoelectric remote control separator according to an embodiment of the present invention, and FIG. 2 is a detailed block diagram of a switch unit.

1, an active thermoluminescent remote control separating apparatus according to an embodiment of the present invention includes a thermoelectric battery 100, a thermoelectric separator 200, a remote controller 300, and an electric load 400, The thermoelectric separator 200 includes a switch unit 210, a measuring unit 220, a power supply unit 230, and a cooling unit 240.

The thermocouple separator 200 receives the separation signal from the remote controller 300 and drives the switch unit 210 to separate the thermocouple 100 from the electric load 400. However, the present invention is not limited to this, and the thermoelectric separator 200 may have a structure including a thermoelectric battery 100 therein.

The remote controller 300 may include a lamp or a separate recognizer so as to confirm the active state of the thermoelectric battery 100. When an operator operates a switch (not shown) included in the remote controller 300, a control signal is transmitted to the switch unit 210 to operate the thermocouple separator 100. The remote controller 300 may include a circuit for detecting an overcurrent or an abnormal high temperature of the thermocouple through the measuring unit 220 and automatically generating a separation signal (or command). The abnormally high temperature of the thermocouple may occur due to a problem (failure) in the thermocouple and may occur when a short-circuit accident occurs in the electrical load 400. [

The power supply unit 230 is a power supply independent of the thermocouple power supply and supplies DC power for operation of the switch unit 210, the measurement unit 220 and the remote controller 300. The power supply unit 230 may be included in the remote controller 300 as needed.

The measuring unit 220 may be a circuit for measuring the current of the output pin of the thermocouple 100 using a Hall sensor to check the active state of the thermocouple 100. A recognition device such as a lamp that can confirm the active state of the thermal battery 100 is applied to both the thermal battery separator 200 and the remote controller 300. The circuit of the measuring unit 220 is configured not to affect the electric load due to the measuring unit 220. The measuring unit 220 may include a circuit for measuring the temperature and voltage of the thermocouple 100 if necessary, and may be disposed at the front end of the switch unit 210.

2, the switch unit 210 includes an electronic switch 20 that operates in response to a switch control signal from the remote controller 300, a mechanical switch 21 that operates manually, And a motor drive switch 22 for driving the fan motor. The motor drive switch 22 may be commanded from the remote controller 300 or may be driven directly by the switch unit 210. [ Particularly, the mechanical switch 21 is not an essential configuration as an additional switch in case the other switch (motor drive switch and electronic switch) fails, and can be replaced with an electronic switch.

 The cooling unit 240 includes a fan motor that is driven using the output power of the thermal battery 100. The fan motor can be driven by the motor drive switch 22. Since the fan motor is driven by using the power source of the thermal battery 100, the fan motor also has a function of shortening the discharge time of the thermal battery 100. In addition, a power consumption device such as an exothermic resistance may be included in order to shorten the discharge time of the thermal battery 100.

In the present invention, the control signal is a name of a signal for controlling each unit, and may include a power control signal, a separation signal, and a switch control signal.

The operation of the active thermo-couple remote control separator according to the embodiment of the present invention will be described with reference to the accompanying drawings.

The active thermoluminescent remote control separation method according to the embodiment of the present invention includes the steps of: driving the thermoelectric battery 100 under the control of the remote controller 300; Switching an output power of the driven thermocouple to an electric load through a thermoelectric separator (200) to perform a power consumption test of the electric load (400); When the test of the electric load (400) is finished, determining the end of test form by the remote controller (300); The remote controller 300 controls the thermoelectric separator 200 to shut off the output power of the thermoelectric battery 100 delivered to the electrical load 400 and selectively cool the thermoelectric battery 100 And discharging the battery.

When the determined end of the test is an abnormal termination due to a normal termination or an abnormality of an electrical load, the thermoelectric separator 200 may supply the thermocouple 200, which is transmitted to the electrical load, in response to a shutoff signal of the remote controller 300, The thermal power can be cooled and discharged by driving the fan motor with the remaining power of the thermal battery.

If the determined end of the test is an abnormal end due to a thermal battery abnormality according to an embodiment of the present invention, the thermoelectric separator 200 cuts off the output power of the thermocouple delivered to the electric load in accordance with the shutoff signal of the remote controller 300 , The thermal battery may not be cooled and discharged.

3 is a flowchart illustrating an active thermal battery remote control separation operation according to an embodiment of the present invention.

Referring to FIG. 3, the operation of the active thermoelectric remote controller according to the embodiment of the present invention starts with supplying power to each unit by operating the power unit 230 (S100). That is, when the operator operates the switch (not shown) included in the remote controller 300, the power control signal is input to the power supply unit 230 of the thermoelectric separator 200, and each unit is operated by the power of the power supply unit 230 The thermocouple separator 200 operates. The remote controller 300 outputs a switch control signal to the switches 20 and 22 of the switch unit 210 to form a path through which the output power of the thermocouple 100 is transmitted to the electrical load 400.

In this state, if a squib drawing command is applied to the pin of the thermal battery 100 according to the test procedure, the thermal battery 100 is activated (driven) to start power consumption (S110).

The output power of the thermoelectric battery 100 is applied to the electric load 400 via the switches 20 to 22 and the measuring unit 220 of the switch unit 210 so that the electric load 300 ) Is performed. At this time, the measuring unit 220 measures the current flowing through the output power source of the thermoelectric battery 100 and the surface temperature of the thermoelectric battery 100 using the Hall sensor to check the activation, power supply, and normal operation of the thermoelectric battery 100, 300 may sense an overcurrent or abnormally high temperature through the measuring unit 220 and may generate a separation signal (or command) when an abnormal situation occurs.

When the power consumption test of the electric load 400 is completed, the remote controller 300 determines the end of test mode (S120, S130). The termination of the test may include a normal termination, an electrical load abnormality, and a thermal battery abnormality condition.

The remote controller 300 cuts off the output power of the thermoelectric battery 100 that is transferred to the electric load 400 in step S150 and the cooling unit 240 The remaining power of the thermocouple 100 is applied to the thermocouple 100 to promote the power consumption (discharge) of the thermocouple and to cool the thermocouple (S160, S170).

That is, the remote controller 300 generates a shutoff signal (switch control signal) to the switch unit 210 of the thermoelectric separator 200 to remotely and safely disconnect the connection between the thermal battery 100 and the electric load 400. The electronic switch 20 is cut off by the cutoff signal, and the mechanical switch 21 is driven. The remote controller 300 drives the motor drive switch 22 through the control signal so that the residual output power of the thermocouple 100 is applied to the cooling power of the cooling unit 240 to activate the cooling unit 240 . The fan motor of the cooling unit 240 is driven by using the residual output power of the thermocouple 100 so that the power consumption of the thermocouple 100 is promoted to shorten the discharge time (accelerate) (S170).

Accordingly, when the thermal cell 100 is discharged and cooled by the fan motor of the cooling unit 240, the operator can safely disconnect the thermal cell 100 from the thermal cell separator 200 after the cooling of the thermal cell is confirmed (S210). At this time, the fan motor may further include a power consumption device such as a heating resistor for shortening a discharge time of the thermal battery 100. [

On the other hand, when the thermal battery 100 is overheated, there is a risk of explosion, and thus securing safety is one of the important tasks. The overheating of the thermal battery 100 occurs for a variety of reasons, one of which is an internal failure of the thermal battery 100. If an abnormality occurs inside the thermocouple, the internal temperature of the battery generally rises rapidly and the output voltage decreases. This rapid rise in temperature causes an increase in the internal pressure. In some cases, however, the failure may end in information that only increases in temperature, but explosion may occur depending on the degree of internal pressure.

The remote controller 300 drives the mechanical switch 21 to turn on the output power of the thermocouple 100 to be delivered to the electrical load 400. If the end of the test is abnormal (S180) The operation of driving the fan motor by applying the remaining power of the thermal battery 100 to the cooling unit 240 is not performed because the trouble of the thermal battery 100 itself occurs. Thereafter, the thermoelectric battery 100 is self-discharged and thermally cooled (S200). The operator separates the thermoelectric battery 100 from the thermoelectric separator 200 after confirming that the thermoelectric battery is cooled (S210).

That is, when an abnormal situation such as a thermal battery internal failure occurs, the remote controller 200 senses that the thermocouple surface rises to an abnormally high temperature through the measuring unit 220 and outputs a separation signal (or command) to the thermocouple separator 200, So as to remotely disconnect the connection between the thermal battery 100 and the electric load 400. In this case, since the thermal battery 100 itself has a problem, the operation of driving the fan motor with the residual power of the thermal battery 100 is not performed.

The present invention can be applied to a case where an overcurrent occurs due to overheating of the thermocouple 100 as well as an overcurrent due to a short circuit of the load 400. The remote controller 300 is connected to the thermocouple 100 through the connection Lt; RTI ID = 0.0 > remotely < / RTI > For this purpose, a separate measuring unit for detecting an overcurrent flowing through the electric load 400 may be provided, and a shutoff signal may be generated according to a signal sensed by the measuring unit.

When disconnecting the thermocouple 100 from the electrical load 400 due to a short circuit of the electrical load 400, the remote controller 300 outputs a shutoff signal (switch control signal) to shut off the electronic switch 20 The motor drive switch 22 is driven to activate the cooling unit 240 of the thermocouple 100 by applying the residual power of the thermocouple 100 to the cooling power of the cooling unit 240. The fan motor of the cooling unit 240 is driven by a residual power source of the thermal cell 100 to cool the thermal cell 100 while discharging the remaining power of the thermal cell 100. When the thermal cell 100 is cooled and discharged by the fan motor of the cooling unit 240, the operator can safely separate the thermal cell 100 from the thermal cell separator 200 (S140 to S170).

As described above, according to the present invention, when the test of the electric load using the thermocouple is completed, or when the thermocouple or the abnormal condition occurs in the electric load, the connection of the thermocouple and the electric load is remotely and securely separated, There is an advantage that it is possible to prevent safety accidents that may occur during development and to separate the electric load connection from the thermal battery more easily and safely.
