Description

Parking Breaker That Works Even In The Event Of Blackout

The present invention relates to a parking circuit breaker that automatically opens in the event of a power failure. More specifically, the present invention relates to a parking breaker that automatically raises the cut-off bar with auxiliary power when the main power is cut off and the input power is cut off while the cut-off bar is lowered.

Parking blockers are used to check and control the traffic of vehicles and pedestrians in parking lots or specific buildings. Usually, a parking blocker is composed of a blocking bar extending horizontally with the floor and a driving means for vertically moving the blocking bar. The parking blocker controls the passage of vehicles and pedestrians by moving the blocking bar horizontally on the floor or vertically on the floor by electric energy and kinetic energy transmitted from the driving means.

Until now, most parking circuit breakers are stopped after the installed barrier bar is lowered, and if a power outage occurs, the operation is stopped while the barrier bar is lowered. At this time, the manager raises the blocking bar so that the vehicle can pass smoothly. However, as the breaker is forcibly operated by an administrator, an irregular load is transmitted to the driving means, and a problem in which the parking cut-off device fails due to this problem has arisen.

In addition, such a parking circuit breaker 100 prevents the administrator from forcibly lifting the blocking bar 101 even when the first AC current is cut off from the main power source, and an irregular load is transmitted to the driving means. This prevents the problem of the parking blocker 100 from being broken.

Such a parking circuit breaker 100 may accommodate a motor (not shown) for raising and lowering the circuit breaker control unit 102 and the blocking bar 101 as shown in FIG. 2 therein.

When AC power is applied between the 1b contact (NC: Normal Connect) relay that is switched to the turn-off state in the first power input terminal (R1_14) and the second power input terminal (R1_13), the turn-off state is turned on. It includes a 1a contact (NO: Normal Open) relay that is converted to. In addition, AC power is applied between the third power input terminal (R2_14), the fourth power input terminal (R2_13), the third power input terminal (R2_14) and the fourth power input terminal (R2_13), and the second relay switch 122 is turned on. When AC power is applied between the 2b contact (NC: Normal Connect) relay, which is converted from the state to the turn-off state, and the third power input terminal (R2_14) and the fourth power input terminal (R2_13), it turns on from the turn-off state. It includes a second a contact (NO: Normal Open) relay that is converted to a state.

The first relay switch 121 and the second relay switch 122 are formed of the same switch and may be formed of a switch having a plurality of contact points, as shown in FIG. 4A. Here, in the first relay switch 121, the first power input terminal (R1_14) is connected to the first output terminal (C1), the second power input terminal (R1_13) is connected to the second output terminal (C2), and the 1a contact relay (R1_9). , 1) is installed between the first output terminal C1 and the second output terminal C2, and the 1b contact relays R1_12 and 4 are installed in the third output terminal C3.

At this time, the 1b contact relays R1_12 and 4 and the 1a contact relays R1_9 and 1 move simultaneously when the first AC power or the second AC power is applied. In addition, in the second relay switch 122, the third power input terminal R2_14 is connected to the third output terminal C3, the fourth power input terminal R2_13 is connected to the fourth output terminal C4, and the 2a contact relay R2_9, 1) is connected to the third output terminal C3, and the 2b contact relays R2_12 and 4 are connected to the third output terminal C3. Here, the 2b contact relays R2_12 and 4 and the 2a contact relay R2_9 and 1 move simultaneously when the first AC power or the second AC power is applied.

In particular, the 1a contact relays (R1_9, 1), the 2a contact relays (R2_9, 1) and the 1b contact relays (R1_12, 4), and the 2b contact relays (R2_12, 4) have an interlock circuit structure. It is connected to the first circuit breaker 111 and the second circuit breaker 112 and prevents the power output from the main power and auxiliary power from being simultaneously applied to the motor.

That is, the 1a contact relay (R1_9, 1), the 2a contact relay (R2_9, 1), the 1b contact relay (R1_12, 4), and the 2b contact relay (R2_12, 4) are the first AC power supply from the main power supply. When outputting, the second AC power is not output from the auxiliary power, and when the first AC power is not output from the main power, the second AC power is output from the auxiliary power. As described above, the 1a contact relay (R1_9, 1), the 2a contact relay (R2_9, 1), the 1b contact relay (R1_12, 4), and the 2b contact relay (R2_12, 4) are composed of an interlock circuit structure, and thus the main It fundamentally cuts off the danger caused by the flow of power and auxiliary power together.

Here, in the first relay switch 121, the 1a contact relay R1_9, 1 is connected in series with the first magnetic connectors MC1 and 131, and is connected to the first output terminal C1 and the second output terminal C2. Can be connected. In addition, the second relay switch 122 may be connected to the fourth output terminal C4 through the second timer 142 and the second magnetic connector 132 and MC2.

The first magnetic connector 131 and the second magnetic connector 132 have a total of 6 contacts, such as points L1, L2, T1, T2, A1, and A2, as shown in Fig. 4(c). It becomes a switch to have.

Here, the first magnetic connector 131 has one end, i.e., point A1 is connected to one end and the other end of the 1b contact relay, that is, point A2 is connected to the second output terminal and point L1 is connected to the first output terminal, and the point L2 is connected to the second output terminal. Points T1 and T2 are connected to the load end. And the second magnetic connector 132 has one end, that is, A1 point is connected to the third output terminal, the other end, that is, A2 point is connected to the fourth output terminal, L1 point is connected to the first output terminal, L2 point is connected to the second output terminal, and T1 , T2 point is connected to the load end.

When AC power is applied to points A1 and A2, the first magnetic connector 131 and the second magnetic connector 132 are converted from a turn-off state to a turn-on state, and when the AC power is cut off. It is converted from turn-on state to turn-off state, and can supply current to the load terminal or cut off the supplied current. That is, the first magnetic connector 131 and the second magnetic connector 132 operate like a contact a (normal open) relay type switch and control the current supplied to the load end.

The first magnetic connector 131 and the second magnetic connector 132 are not damaged by the applied high current, so that current can be safely applied to the load. That is, the first magnetic connector 131 and the second magnetic connector 132 ensure the safety of the load.

The first timer 141 corresponds to the conduction of current between the first time power input terminal (T1_7), the second time power input terminal (T1_2), and the first time power input terminal (T1_7) and the second time power input terminal (T1_2). It includes a first time switch (T1_8, 5 or 6) that is opened and closed. Here, in the first timer 141, the first time power input terminal (T1_7) is connected to the third output terminal (C3), the second time power input terminal (T1_2) is connected to the fourth output terminal (C4), and the first time switch (T1_8, 5 or 6) may be connected to the third output terminal (C3) and the fourth output terminal (C4).

When an AC current is conducted between the third output terminal (C3) and the fourth output terminal (C4), the first timer 141 closes the first time switch and the first time switch (T1_8, 5) and the third output terminal (C3) and A voltage is formed between the fourth output terminals C4. In addition, a current corresponding to the voltage thus formed is applied to the load. On the other hand, when the AC current does not conduct between the third output terminal (C3) and the fourth output terminal (C4), the first timer 141 opens the first time switch (T1_8, 6) to apply voltage and current to the load. Do not.

The second timer 142 responds to the conduction of current between the third time power input terminal (T2_7), the fourth time power input terminal (T2_2), and the third time power input terminal (T2_7) and the fourth time power input terminal (T2_2). It includes a second time switch (T2_1, 3 or 4) that is opened and closed.

Here, in the second timer 142, the third time power input terminal (T2_7) is connected to the third output terminal (C3), the fourth time power input terminal (T2_2) is connected to the fourth output terminal (C4), and the second time switch (T2_1, 3 or 4) may be connected between the third output terminal (C3) and the fourth output terminal (C4).

When AC current is conducted between the third output terminal (C3) and the fourth output terminal (C4), the second timer 142 closes the second time switch (T2_1, 3 or 4), and the third output terminal (C3) and the fourth output terminal Allow a voltage to be formed between (C4). And the thus formed voltage is applied to the load. On the other hand, the second timer 142 opens the second time switch (T2_1, 3 or 4) when the AC current does not conduct between the third output terminal (C3) and the fourth output terminal (C4) to apply a voltage to the load. Do not.

The first circuit breaker 111, the second circuit breaker 112, the first relay switch 121, the second relay switch 122, and the first magnetic connector 131, and the second magnetic connector 132 as described above. ), the circuit breaker control unit 102 including the first timer 141 and the second timer 142 may be formed as a circuit as shown in FIG. 5.

Hereinafter, the circuit structure of the circuit breaker control unit will be described in detail with reference to FIG. 5. 5 is a circuit diagram of a circuit breaker control unit of FIG. 3.

The breaker control unit 102 is largely formed in a circuit structure including a first circuit and a second circuit. Here, in the first circuit, the second b contact relays (R2_12, 4) are connected to the first output terminal (C1), and the first power input terminal (R1_14) of the first relay switch is connected to the first output terminal (C1) and the second output terminal (C2). ) And the second power input terminal (R1_13) are connected, the 1a contact relay (R1_9, 5 or 1) between the first output terminal (C1) and the second output terminal (C2), and the first magnetic connector (MC1,131) Is formed in a connected structure. And in the second circuit, the circuit breaker control unit 102 has a first contact relay (R1_12, 4 or 8) connected to the third output terminal (C3), and between the third output terminal (C3) and the fourth output terminal (C4). The first time power input terminal T1_7 and the second time power input terminal T1_2 of the timer are connected, and the first time switches T1_8 and 5 of the first timer are connected to the third output terminal C3. In addition, the third power input terminal R2_14 and the fourth power input terminal R2_13 are connected between the third output terminal C3 and the fourth output terminal C4. And the 2a contact relay (R2_9, 5) is connected, the first time power input terminal (T2_7) and the second time power input terminal (T2_2) of the second timer between the third output terminal (C3) and the fourth output terminal (C4) Is connected, and a second time switch and a second magnetic connector (MC, 132) are connected between the third output terminal (C3) and the fourth output terminal (C4).

The circuit breaker control unit 102 is the second AC voltage of the second AC power supply immediately when the first AC voltage of the first AC power source is applied to the converter or the first AC voltage is not applied through the first circuit and the second circuit. Make it possible to apply to this converter. And the converter drives the motor, that is, the load with the output voltage, and raises and lowers the cut-off bar.

In addition, the voltage output from the converter may drive not only the motor, but also a calculator that drives the motor and a sensor installed in the cut-off bar 101. In more detail for each device, the converter becomes a device that converts AC to DC, and the calculator calculates the changed DC and the signal received from the sensor to output the first signal or the second signal, and the first AC power is cut off. When the AC voltage output from the second AC power source is applied, it becomes a device that outputs a second signal. In addition, the motor may be a device that receives a first signal and rotates in a forward direction, receives a second signal and rotates in a reverse direction, and raises and lowers the blocking bar 101.

The 1a contact relays (R1_9, 1) and the 1b contact relays (R1_12, 4) included in the breaker control unit 102, and the 2a contact relays (R2_9, 1) and the 2b contact relay (R2_12, 4) are the first When AC power or the second AC power is applied, it moves simultaneously.

The 1a contact relays (R1_9, 1), the 2a contact relays (R2_9, 1), the 1b contact relays (R1_12, 4), and the 2b contact relays (R2_12, 4) are used to output the first AC current from the main power supply. In this case, the second AC current is not output from the auxiliary power supply, and when the first AC current is not output from the main power supply, the second AC current is output from the auxiliary power supply. That is, the 1a contact relay (R1_9, 1 or 5), the 2a contact relay (R2_9, 1 or 5), the 1b contact relay (R1_12, 4 or 8), and the 2b contact relay (R2_12, 4 or 8) are It is connected to the first circuit breaker 111 and the second circuit breaker 112 in an interlock structure so that the AC current output from the main power and auxiliary power is not simultaneously applied to the load.

Hereinafter, a process in which a current flows, a voltage is formed, and a voltage is applied to a load in the circuit diagram of the circuit breaker control unit will be described in detail with reference to FIGS. 6 to 8.

6 to 8 are diagrams showing a state in which a relay switch, a timer, and a magnetic connector are operated when the first circuit breaker is applied with the main power and when the second circuit breaker is applied with the auxiliary power, and electricity is applied to the blocking bar. .

As shown in FIG. 6, the first circuit of the circuit breaker control unit 102 maintains the closed state of the second b contact relays R2_12 and 4 so that the first AC current flows from the beginning. Accordingly, the first AC current passes through the third power input terminal (R2_14) and the fourth power input terminal (R2_13) of the first relay switch from the first AC power source, and the first voltage is formed to form the first contact relay. (R1_9, 1) and the first magnetic connector 131 are closed. Then, the current output from the first magnetic connector 131 is applied to the load. The first circuit of the circuit breaker control unit 102 always operates as described above while the first AC current is output from the first AC power source and allows current to be applied to the load.

On the other hand, when a problem occurs in the first AC power source, for example, when a power failure occurs, the second AC power source may operate as shown in FIG. 7.

At this time, the second circuit of the circuit breaker control unit 102 is in a state where the first b contact relays R1_12 and 8 are closed so that the second AC current flows through the third output terminal C3. At this time, the 1b contact relays R1_12 and 4 are closed at the same time as the 1a contact relays R1_9 and 5 are opened. Then, a second AC current is output from the second AC power source and passes through the first time power input terminal T1_7 and the second time power input terminal T1_2 of the first timer to close the first time switches T1_8 and 5. . As a result, a second AC current flows through the third power input terminal R2_14 and the fourth power input terminal R2_13, so that the second contact relays R2_9 and 5 are closed. As a second AC current flows through the first time power input terminal T2_7 and the second time power input terminal T2_2 of the second timer, the second time switches T2_1 and 4 and the second magnetic connector MC2, 132) will be closed. At the same time, the second circuit allows the current output from the second magnetic connectors MC2 and 132 to be applied to the load.

At this time, the second timer 142 allows the second AC power of the second AC power to be applied to the load when the first AC power is cut off for the second time and the second AC power is applied for the second time. The first timer 141 may form the third output terminal C3 as a closed circuit for a first time longer than the second time period, and then form the third output terminal C3 as an open circuit after the first time.

Here, the second time is a time as to whether to operate the second magnetic connector after a few seconds when electricity is supplied through the auxiliary power due to a power outage. At this time, the second timer allows current to flow through the second magnetic connector after the set time has elapsed from 0 seconds as much as the time set. The first time is a time for stopping the supply of current to the second relay switch, the second timer, and the second magnetic connector after a few seconds so as to be in a dormant state. If the first time is prolonged, even if a power failure occurs, the cut-off bar can continue to operate normally as much as the capacity of the auxiliary power supply.

In the name of the description in this specification, the second time set in the second timer is 3 seconds and the first time is 10 seconds.

When a problem occurs in the first AC power source and the first AC current is not applied to the second circuit of the circuit breaker control unit 102, as shown in FIG. 8, the second time switches T2_1 and 4 are opened. It stays closed after 3 seconds and allows current to be applied to the blocking bar.

At this time, the first time switches T1_8 and 6 remain closed for 10 seconds and then are converted to an open state. As the first time switch is opened in this way, the second AC current is not applied to the second relay switch and the second timer located at the rear end of the first time switch. That is, the second circuit of the circuit breaker control unit 102 checks whether a problem occurs in the first AC power for a second time, and if a problem occurs, the cut-off bar rises within 10 seconds, and then the second magnetic connector 132 Cut off the power supplied to the device. And until the main power is restored, all operations are stopped and the cut-off bar is in a standby state.

At this time, the second circuit charges the auxiliary power source, that is, the battery 200 with the flow of current as shown in FIG. 9 while the blocking bar is in the standby state.

In this way, the breaker control unit 102 allows the cut-off bar 101 to operate when the main power is operating normally and when the main power does not operate normally, and allows an administrator who manages the parking breaker 100 to easily manage the breaker. Then, the battery 200 is charged.

Hereinafter, with reference to FIGS. 10 to 14, a parking circuit breaker that operates even during a power outage according to another embodiment of the present invention will be described.

However, in order to clearly concise the description of the parking circuit breaker even during a power outage of another embodiment of the present invention, the description of the same components as the parking circuit breaker during a power failure of the above-described embodiment is omitted, The sub, first branch, second branch, branch power supply, 3a contact (NO: Normal Open) relay, and 3b contact (NC: Normal Connect) relay will be described in detail.

10 is a perspective view of a parking circuit breaker that operates even during a power outage according to another embodiment of the present invention, and FIG. 11 is a circuit diagram of a circuit breaker control unit according to another embodiment of the present invention.

The parking circuit breaker 100-1, which operates even during a power outage according to another embodiment of the present invention, in the first AC power supply of the circuit breaker control unit 102-1 when a part of the parking blocking unit 110 is flooded due to heavy rain. Cut off the output current.

In this way, the parking circuit breaker 100-1, which operates even in the event of a power outage, operates so that when a certain level of rain falls, the manager is not electrocuted.

In addition to the components constituting the parking circuit breaker 100 that operates even during a power outage, the parking circuit breaker 100-1 that operates even during a power outage is a rainwater receiving unit 300, a first branch (B1), and a second branch. (B2), a branch power supply terminal (D), a 3a contact (NO: Normal Open) relay, and a 3b contact (NC: Normal Connect) relay.

The rainwater receiving unit 300 may be installed inside or outside the parking blocking unit 110 to receive rainwater falling. As shown in FIG. 10, the rainwater receiving unit 300 may accommodate a receiving space formed inside the parking blocking unit 110 when it rains or when rainwater accumulates. However, the installation location of the rainwater receiving unit 300 is not limited to the interior of the parking blocking unit 110 and may be installed outside the parking blocking unit 110 as necessary. In addition, the rainwater receiving part 300 has a first branching end B1 branching from the first output end C1 and a second branching end B2 branching from the second output end at a height spaced upward from the bottom surface. Is accepted.

The first branch terminal B1 becomes a wire branched from the first output terminal C1, and the second branch terminal B2 becomes a wire branched from the second output terminal C2.

The branch power terminal D is a wire that is branched from the first output terminal C1 and supplies power to the first magnetic connector 131. The branch power supply terminal D allows the first AC current output from the first AC power to be applied to the first magnetic connector 131 together with the second output terminal C2.

The 3b contact (NC: Normal Connect) relay (R3_12, 4) is installed in the branch power terminal (D) and turns from the turn-on state when current flows through the first branch terminal (B1) and the second branch terminal (B2). -It is a switch that is converted to the off state. And the 3a contact (NO: Normal Open) relay (R3_9, 1 or 5) is converted from a turn-on state to a turn-off state when current flows through the first branch terminal (B1) and the second branch terminal (B2). It's a switch.

Hereinafter, the operation state of the circuit breaker control unit will be described in detail when the rainwater is filled and not filled in the rainwater receiving unit with reference to FIGS. 12 to 14.

When the first AC power is normally operated, the circuit breaker control unit 102-1 applies a current to the first magnetic connector MC1 as shown in FIG. 12, and the first magnetic connector MC1 The auxiliary power supply 200 is charged with the output current. At this time, the 3b contact (NC: Normal Connect) relay (R3_12, 4) is formed in the second output terminal (C2), the second output terminal is connected, and the first output terminal is connected to the rainwater receiving unit 300 through rainwater. Allow current to flow through (C1) and the second output terminal (C2).

As shown in FIG. 12, even if rainwater is filled in the rainwater receiving unit 300, when the first branching end B1 and the second branching end B2 are not filled, or the rainwater receiving unit 300 is filled with rainwater. If not, the AC current of the first AC power is applied to the first magnetic connector MC1 through the branch power line D and the first relay switch 121. In addition, the current output from the first magnetic connector MC1 causes the load to operate.

On the other hand, as shown in FIG. 13, when rainwater is filled in the rainwater receiving part 300 and the rainwater is filled up to the first branching end B1 and the second branching end B2, the first branching end B1 and A current flows through the second branch terminal B2. When a current flows through the first branch terminal B1 and the second branch terminal B2, the 3b contact (NC: Normal Connect) relay is immediately switched from the turn-on state to the turn-off state. In addition, the 3a contact (NO: Normal Open) relay located at the branch power terminal D is converted from a turn-off state to a turn-on state. That is, when a current flows between the first branch (B1) and the second branch (B2), the 3b contact (NC: Normal Connect) relay and the 3a contact (NO: Normal Open) relay interlock, and the rainwater receiving part If rainwater fills up to a certain level in (300), the first AC power supply should not be operated.

When the rainwater in the rainwater receiving unit 300 differs by a certain level and the first AC power does not operate, the second AC power, that is, the second AC power, is output from the battery 200 as shown in FIG. 14. At this time, the output second AC power operates the second magnetic connector 132. In addition, the load is operated through a current output from the second magnetic connector 132.

That is, the parking circuit breaker 100-1, which operates even during a power failure, operates the blocking bar 101 by the operation of the second AC power when a certain level of rain is filled in the rainwater receiving unit 300, and the rainwater receiving unit 300 If a certain level of rain is not filled in ), the blocking bar 101 is raised by the operation of the first AC power source.

The parking circuit breaker (100-1), which operates even in the event of a power outage, operates in this way, and in case of rainfall, that is, a lot of rain, the blocking bar (101) is prevented from being operated by the first AC power source, and the manager is electrocuted by the first AC power source. Avoid accidents.
