In addition, in the accompanying drawings, like reference numerals refer to like components.

1 is a flowchart schematically illustrating a method for controlling field equipment according to embodiments of the inventive concept.

Referring to FIG. 1, a schedule registration step S10 is first performed. During the schedule registration step (S10), the schedule may be downloaded from the server, or the schedule may be registered by the administrator directly inputting the schedule. The schedule may be defined as a timetable for processing a target to be controlled (for example, local equipment) in time. For example, in the case of an air conditioner installed in a classroom, the schedule may be a timetable of whether the air conditioner is operated for each time zone.

After that, it is determined whether the schedule is downloaded from the server (S20). If the schedule is downloaded from the server, the schedule is applied in the individual scheduling mode (S30). During the individual scheduling mode, schedule processing may be performed for each subject (eg, local equipment). That is, each of the plurality of local devices may be individually controlled during the individual scheduling mode.

If the schedule is not downloaded from the server and the administrator directly inputs the schedule, it is checked whether the input schedule is grouped (S40). If the input schedule is a group, the schedule is applied in a group scheduling mode (S50). During the group scheduling mode, local devices that need to have the same control are bundled and grouped so that the local devices can be scheduled. If the input schedule is not a group, the schedule is applied in the individual scheduling mode (S60).

After that, it is determined whether the schedule is activated, that is, whether to use the schedule (S70). If the schedule is not activated, the power of the local equipment may be arbitrarily controlled (S80). For example, the local device may be controlled by an authenticated user as well as an authenticated user. If the schedule is activated, the scheduling mode of the activated schedule is checked (S90). More specifically, it is determined whether the activated schedule is a scheduling mode or an authority mode.

If the activated schedule is in scheduling mode, the local equipment can only be controlled by the schedule. First, check the schedule state (S100). If the schedule status is a free status, the power of the local equipment may be arbitrarily controlled (S110). Since the schedule is activated but there is no control value, the local device can be controlled not only by the authenticated user but also by an unauthorized user.

When the schedule status is a control status, the power of the local equipment may be controlled according to the operation signal according to the schedule (S120). Since the schedule is activated and there is a control value (for example, an operation signal) according to the schedule, the local device is not controlled by the authenticated user and the unauthorized user.

When the activated schedule is in the privileged mode, the local device is controlled by the schedule, and the schedule may be modified in the schedule free mode by the designated time when the authenticated user controls the schedule. First, check the schedule state (S130). If the schedule status is a free status, the power of the local equipment may be arbitrarily controlled (S140). Since the schedule is activated but there is no control value, the local device can be controlled not only by the authenticated user but also by an unauthorized user.

When the schedule status is a control status, the power of the local equipment may be controlled according to the operation signal according to the schedule (S150). The schedule is activated and there is a control value (eg, an operation signal) according to the schedule. In this case, although the local device is not controlled by the authenticated user and the non-authenticated user in the scheduling mode, the local device may be controlled by the authenticated user in the authorization mode.

More specifically, the authenticated user may perform an authentication operation through a management terminal (for example, a PC connected with WEB), and after the authentication operation is performed, the local device may be in an authority free state for a predetermined time. have. During the rights free state, authenticated users and unauthorized users can arbitrarily control local equipment.

FIG. 2 is a flowchart illustrating in more detail an operation according to a control state of a scheduling mode and a control state of a privilege mode in the field equipment control method of FIG. 1.

Referring to FIG. 2, it is first determined whether a scheduling mode or a privilege mode is used (S70). In the scheduling mode, when the schedule status is the control status, the power of the local equipment may be controlled according to the operation signal according to the schedule as described above (S120). To this end, a first operation signal according to a schedule may be generated, and the first operation signal may be transmitted to the local equipment (S123). Local equipment may be controlled by receiving the first operation signal.

In the scheduling mode, when the schedule state is in the control state, the schedule is in an active state and there is a control value (for example, an operation signal) according to the schedule. Therefore, local devices are not controlled by authenticated and unauthorized users. To this end, an authority restriction signal may be generated, and the authority restriction signal may be transmitted to a local device (S125).

In the privilege mode, when the schedule status is a control status, the power of the local equipment may be controlled according to the operation signal according to the schedule as described above (S150). To this end, a second operation signal according to a schedule may be generated, and the second operation signal may be transmitted to the local equipment (S153). Local equipment may be controlled by receiving the second operation signal.

In the privileged mode, when the schedule state is in a control state, the schedule is in an active state and there is a control value (for example, an operation signal) according to the schedule, but the local device can be controlled by an authenticated user. The authenticated user may perform an authentication operation through the management terminal, and after the authentication operation is performed, the local device may be in an authority free state for a predetermined time. To this end, an authority free signal may be generated in response to the authentication signal received from the management terminal, and the authority free signal may be transmitted to the local device (S155). The local device may be in the privilege free state by receiving the privilege free signal.

3 and 4 are tables showing schedules to which the method of controlling the field equipment of FIG. 1 is applied. 3 shows a context table in scheduling mode, and FIG. 4 shows a context table in privileged mode.

1 and 3, in the case of the N state, when the schedule is not activated, it corresponds to step S80. During the N state, the local equipment can be controlled by any user. That is, not only the verified user connecting through the management terminal, but also any third party can control the local equipment.

In the case of the S-1 state, the schedule is activated but there is no operation signal (for example, a power ON / OFF command) at the corresponding time in the schedule. Thus, as well as a verified user connecting through the management terminal, any third party can also control the local equipment.

In the case of the S-2 state, an operation signal of the first state (eg, a power OFF command) is present at a corresponding time of the schedule. In the case of the S-3 state, the operation signal of the second state (for example, a power-on command) is present at a corresponding time of the schedule. In the case of the S-2 state and the S-3 state, the local equipment is controlled only by the operation signal.

For example, during the S-2 state and the S-3 state, an operation disable message window may be displayed for a request of a verified user connecting through the management terminal. In addition, even if any user controls the local equipment, the operation signal generated by the control becomes invalid and the local equipment is controlled only by the operation signal generated according to the schedule.

1 and 4, in the case of the N state, the schedule is not activated and corresponds to step S80. As described above, during the N state, the local equipment may be controlled by any user.

In the case of the A-1 state, the schedule is activated but there is no operation signal (for example, the power ON / OFF command) at the corresponding time in the schedule. Thus, as well as a verified user connecting through the management terminal, any third party can also control the local equipment.

In the case of the A-2 state, an operation signal of the first state (for example, a power OFF command) is present at a corresponding time of the schedule. In the case of the A-3 state, an operation signal (eg, a power-on command) of the second state exists at a corresponding time of the schedule. In the A-2 state and the A-3 state, the local equipment is controlled only by the operation signal.

For example, during the A-2 state and the A-3 state, an operation disable message window may be displayed for a request of a verified user connecting through the management terminal. In addition, even if any user controls the local equipment, the operation signal generated by the control becomes invalid and the local equipment is controlled only by the operation signal generated according to the schedule.

A-4 state is when the schedule control value exists but the schedule is free by the authorized person. By performing the authentication operation during the A-2 state or the A-3 state, the A-2 state or the A-3 state may be changed to the A-4 state.

During the A-4 state, any third party, as well as a verified user connecting through the management terminal, can also control the local equipment. However, the A-4 state lasts for a predetermined time period, after which the state returns to the A-2 state or the A-3 state.

FIG. 5 shows the entire situation table in which the situation table of FIGS. 3 and 4 is reflected.

Referring to FIG. 5, first, during a power saving state, a local device may be changed to an S-1 state, an S-2 state, an A-1 state, an A-2 state, and an A-4 state.

When the power saving state is OFF, it is determined whether the group scheduling mode or the individual scheduling mode. As described above, during the group scheduling mode, local devices that need to have the same control may be bundled and grouped so that the local devices may be scheduled. In addition, during the individual scheduling mode, each of the plurality of local devices may be individually controlled.

During group scheduling mode and individual scheduling mode, the local device is in N state, S-1 state, S-2 state, S-3 state, A-1 state, A-2 state, A-3 state, and A-4 respectively. Can be changed to a state. As described above, by performing the authentication operation during the A-2 state or the A-3 state, the A-2 state or the A-3 state is changed to the A-4 state. Also, the A-4 state may return to the A-2 state or the A-3 state after a predetermined time period.

6 is a flowchart schematically illustrating a method for controlling field equipment according to some embodiments of the inventive concept.

Referring to FIG. 3, it is first determined whether a scheduling mode or an authorization mode is performed (S200). Thereafter, a first step according to the scheduling mode or a second step according to the authorization mode may be performed.

<First Step according to Scheduling Mode>

First, T = 1 is set (S210). Where T represents the current time according to the schedule. Steps S220, S230, S240, and S250 may be performed every hour (that is, T = 1, 2, 3,..., N).

It is determined whether the first terminal operation signal is received from the management terminal (S220). When the first terminal operation signal is received from the management terminal, a first operation disable signal is generated in response to the first terminal operation signal, and the first operation disable signal is transmitted to the management terminal (S230).

Thereafter, a first operation signal and a first authority restriction signal are generated according to a schedule, and the first operation signal and the first authority restriction signal are transmitted to a local device (S240). The local device may receive the first privilege restriction signal, in which case the local device is not controlled by the authenticated and unauthenticated users.

Thereafter, it is determined whether or not to terminate (S250), and if it is not terminated, after setting T = T + 1, steps S220, S230, S240, and S250 are performed again at an increased time T.

As a result, during the scheduling mode, the local equipment is controlled only by the schedule and not by the authenticated and unauthenticated users.

<2nd step according to authority mode>

In the privileged mode, first, T = 1 is set (S310). Where T represents the current time according to the schedule. Steps S310, S320, S330, S340, S350, S380, S390, S400, and S410 may be performed every hour (that is, T = 1,2,3, ..., N).

A second operation signal is generated according to a schedule, and the second operation signal is transmitted to the local device (S320). Thereafter, it is determined whether an authentication signal is received from the management terminal (S330). When the authentication signal is received from the management terminal, the authority free signal is generated during the first time period from the time point at which the authentication signal is received, and the authority free signal is transmitted to the local equipment (S340 and S350). For example, when the first time period is K, T = T + K will be obtained (S350). Although not shown in FIG. 6, as shown in FIG. 5, during the power saving state, steps S340 and S50 may be performed in response to an authentication signal, in which case step S340 may be performed in response to the first time interval. It may be performed for a short second time period.

After step S350, that is, after the first time period, steps S320, S330, S360, S370, and S380 may be performed again. That is, before the authentication signal is re-received from the management terminal, generating a second operation signal and a second authority restriction signal according to the schedule, and transmitting the second authority restriction signal to the local equipment may be performed. There is (S320, S360). The second operation disable signal is generated in response to the second terminal operation signal received from the management terminal until the authentication signal is re-received from the management terminal after the first time period. Transmitting to the management terminal may be performed (S370, S380).

If the authentication signal is not received from the management terminal, it is determined whether a second terminal operation signal is received from the management terminal (S360). When the second terminal operation signal is received from the management terminal, a second operation disable signal is generated in response to the second terminal operation signal, and the second operation disable signal is transmitted to the management terminal (S370).

Thereafter, a second permission restriction signal is generated and the second permission restriction signal is transmitted to the local device (S380). The local device may receive the second permission restriction signal, in which case the local device is not controlled by the authenticated and unauthenticated users.

After the determination whether the end (S390), if not terminated after setting the T = T + 1 (S400), the step (S320, S330, S340, S360, S370, S380, S390) at an increased time T Redo.

As a result, during the scheduling mode, the local device is controlled only by the schedule, not by the unauthorized user, and the authenticated user can control the local device only if the authentication operation is properly performed.

In the control method of the local device according to the technical idea of the present invention, the local device may be controlled only by the authenticated user by introducing an authorization mode. Therefore, the control method allows a limited user to control the local device without purchasing a local device that additionally implements an authentication function.

In the method of controlling local equipment according to the technical idea of the present invention, various types of management terminals can control the local equipment. For example, if local equipment such as a room air conditioner is operating according to a schedule in a privileged mode, an authenticated user such as a teacher may perform an authentication operation using a management terminal such as a computer or a smartphone in the classroom. Therefore, the local device may be in the privilege free mode and controlled for the first time period. That is, user convenience can be increased.

7 and 8 are flowcharts schematically illustrating a method for controlling field equipment according to other embodiments of the inventive concept. The field equipment control method according to these embodiments may be a modification of the field equipment control method according to FIGS. 2 and 6. Duplicate descriptions between the following embodiments will be omitted.

Note that in the case of the previous embodiments, the authority restriction signal and the authority free signal were transmitted to the local equipment in order to control the local equipment, but the present invention is not limited thereto. For example, instead of sending an authorization restriction signal to the local device to prevent an unspecified majority of the local device from being controlled, the local device controls it by continuously sending a second operation signal (or first operation signal) to the local device. Can be. For example, when the second operation signal (or the first operation signal) is a signal for turning off the power of the local equipment, during the authorization mode (or scheduling mode), the second operation signal (or the first operation signal) is Can be sent to the local device continuously. Thus, even if a third party turns on the local equipment, the local equipment may remain turned off by the second operation signal (or first operation signal) continuously received.

In addition, instead of transmitting the rights free signal to the local equipment, the local equipment may be controlled by not transmitting the second operation signal to the local equipment. For example, when the second operation signal is a signal for turning off the power of the local equipment, transmission of the second operation signal to the local equipment may be interrupted during the privilege mode. Therefore, when the third party turns on the local device, the local device may not be turned off by the second operation signal and may remain turned on.

This operation is shown in more detail in FIGS. 7 and 8. Referring to FIG. 7, in the scheduling mode, in a scheduling mode, a first operation signal according to a schedule may be generated (S123a), and the first operation signal may be transmitted to a local device (S123b).

On the other hand, in the authorization mode, a second operation signal according to the schedule may be generated (S153a), and after that it may be determined whether to receive the authentication signal (S157). When the authentication signal is received, the transmission of the second operation signal to the local equipment is blocked (S153b). When the authentication signal is received, the second operation signal is transmitted to the local equipment (S153c).

That is, as described above, when the authentication signal is not received, instead of transmitting an authority restriction signal to the local device so that the unspecified majority of the local device is not controlled, the second operation signal is sent directly to the local device to directly local. By controlling the equipment, arbitrary manipulation by a third party can be prevented. In addition, when an authentication signal is received, instead of transmitting an authority free signal to the local device to allow an unspecified majority to control the local device, the second operation signal is not transmitted to the local device, thereby preventing the operation of the third party. You can keep it from being interrupted.

The above operation may also be applied to the embodiment of FIG. 6. 8 is a partial modification of the embodiment of FIG. Hereinafter, a description overlapping with FIG. 6 will be omitted.

Referring to FIG. 8, in the scheduling mode, step S1240 of generating a first operation signal according to a schedule and transmitting the first operation signal to local equipment instead of step S240 of FIG. 6 may be performed.

In addition, in the authority mode, step S1320 of generating a second operation signal according to a schedule may be performed instead of step S320 of FIG. 6. If the authentication signal is not received, step S1340 of blocking transmission of the second operation signal may be performed instead of step S340 of FIG. 6. In addition, when receiving the authentication signal, step S1380 of transmitting the second operation signal may be performed instead of step S380 of FIG. 6.

9 is a flowchart schematically illustrating an apparatus 500 for controlling field equipment according to some embodiments of the inventive concept. The field equipment control apparatus according to this embodiment may be a field equipment control apparatus using the field equipment control method of FIG. 6.

Referring to FIG. 9, the field equipment control apparatus 500 may include a first transceiver 510, a second transceiver 520, and a controller 530. The first transceiver 510 may be provided for communication with the management terminal T, and the second transceiver 520 may be provided for communication with the local equipment L. FIG.

The controller 530 may be configured to determine whether the scheduling mode or the authority mode, and to control the first transceiver 510 and the second transceiver 520 according to the scheduling mode or the authority mode. .

More specifically, during the scheduling mode, the controller 530 generates a first operation disable signal in response to the first terminal operation signal received from the management terminal T, and the first transceiver 510 generates the first operation signal.
