[0019] Figure 1 This is a structural diagram of a rolling curtain sign centralized control system for a substation terminal screen provided by an embodiment of the present application. The embodiment of the present application can be applied to control the rolling curtain device corresponding to the substation terminal screen to realize the deployment and storage of the rolling curtain sign. Figure 1 As shown, the system includes:

[0020] A centralized control platform 110, a rolling curtain device 120 and a substation terminal screen 130, wherein the centralized control platform 110 is in communication connection with the rolling curtain device 120; the substation terminal screen 130 includes at least one of a DC screen, a simulation screen, a monitoring screen, a protection screen and a sound insulation screen;

[0021] The centralized control platform 110 is used to respond to the trigger operation of the staff and / or detect the input work ticket, and detect the operation of the on-site staff, generate a control instruction according to the trigger operation and / or the detection result, and send the control instruction to the rolling curtain device 120;

[0022] The rolling curtain device 120 is used to receive control instructions sent by the centralized control platform 110, and / or respond to the staff's operation of the switch module on the rolling curtain device 120 to control the deployment or storage of the rolling curtain sign in the rolling curtain device 120.

[0023] Among them, the centralized control platform can be a platform at the same site as the substation terminal screen, or it can be a remote control platform at a remote end. The centralized control platform and the rolling curtain device are respectively integrated with communication modules, and communication can be carried out in a wired or wireless manner. The substation terminal screen can be at least one of a DC screen, a simulation screen, a monitoring screen, a protection screen, and a sound insulation screen. Among them, the DC screen: used to provide DC power supply, usually installed in the substation, to provide a stable DC power supply to ensure the normal operation of the equipment. For example, GZDW-100AH ​​DC screen DC220V DC power supply screen. Simulation screen: used to simulate the electrical equipment and processes of the substation to help operators intuitively understand the operating status of the substation. Common simulation screens include factory simulation screens, high-voltage flow charts of distribution substations, and simulation diagrams of switch stations in power distribution rooms. Monitoring screen: used to monitor various parameters and equipment status of the substation to ensure the safe operation of the substation. The monitoring screen is usually combined with a microcomputer background monitoring system to provide real-time operating condition data and fault analysis functions. Protection screen: used to protect key equipment in the substation and prevent overload, short circuit and other faults from damaging the system. The protection screen can realize remote monitoring and protection of substation equipment through telemetry, telesignaling and remote control functions. Sound insulation screen: used to reduce the impact of noise generated by the substation on the surrounding environment. For example, the sound insulation screen of the power plant substation can reduce noise pollution and protect the quality of life of surrounding residents.

[0024] Figure 1 A specific example of the relative position of a rolling curtain device and a substation terminal screen is given in Figure 1 The roller shutter sign is in the retracted state. The roller shutter device is located at the upper end of the substation terminal screen. When the roller shutter sign is unfolded, the roller shutter sign unfolds from top to bottom to block the substation terminal screen. The shielding effect is as follows: Figure 2 As shown. The rolling curtain device can also be located at the lower end, left end, or right end of the substation terminal screen. If the rolling curtain device is located at the lower end of the substation terminal screen, the rolling curtain sign will unfold from bottom to top during the unfolding of the rolling curtain sign. If the rolling curtain device is located at the left end of the substation terminal screen, the rolling curtain sign will unfold from left to right during the unfolding of the rolling curtain sign. If the rolling curtain device is located at the substation terminal. The rolling curtain sign can be a sign made of red cloth, or it can be made of other materials that can be rolled up and stored. In the stored state, the rolling curtain sign is rolled on the reel, and in the unfolded state, the rolling curtain sign unfolds to block the substation terminal screen.

[0025] Exemplarily, the staff can perform a trigger operation on the centralized control platform, such as triggering a button on the touch screen of the centralized control platform to trigger the control of the rolling curtain device. The staff can also detect the entered work ticket and the operation of the on-site personnel to determine whether the rolling curtain device needs to be controlled, thereby sending a control instruction to the rolling curtain device when the rolling curtain device needs to be controlled. The rolling curtain device can receive the control instruction sent by the centralized control platform, and respond to the control instruction to control the expansion or storage of the rolling curtain sign. A switch module can also be set on the rolling curtain device to directly control the rolling curtain device to expand or store the rolling curtain sign.

[0026] The technical solution of the embodiment of the present application can control the rolling shutter device in response to the trigger operation of the staff, realize the deployment or storage control of the rolling shutter signboard, and can determine whether the rolling shutter device needs to be controlled and whether the rolling shutter signboard needs to be deployed or stored based on the detection of the work ticket by the centralized control platform, and accurately predict the current state of the rolling shutter signboard according to the operation content, operation object and operation time of the work ticket, and control it, thereby improving the intelligence and accuracy of the control.

[0027] As a non-limiting implementation method, the centralized control platform is specifically used to respond to the staff's rolling curtain sign to perform an expansion trigger operation and / or detect the input work ticket, and detect the entry of the on-site staff. If it is determined based on the detection of the work ticket that the current arrival of the work start time set on the work ticket, and it is detected that the on-site staff has successfully entered the site through at least one of the verification methods of card swiping verification, biometric feature verification, and short-range wireless communication technology verification, then a rolling curtain expansion instruction is sent to the rolling curtain device corresponding to the substation terminal screen that does not require operation;

[0028] The rolling curtain device is specifically used to receive a rolling curtain deployment instruction sent by the centralized control platform, and / or in response to a staff member's rolling curtain deployment operation on a switch module on the rolling curtain device, control the rolling curtain sign to deploy to cover the substation terminal screen.

[0029] For example, if the staff performs a deployment trigger operation on the centralized control platform, a rolling curtain deployment instruction is sent to the rolling curtain device, and the rolling curtain device controls the rolling curtain sign to deploy in response to the rolling curtain deployment instruction to cover the substation terminal screen.

[0030] If the work start time set by the work ticket is determined based on the detection of the work ticket, and it is detected that the on-site staff has successfully entered the site through at least one of the verification methods of card swiping, biometric feature verification, and short-range wireless communication technology verification, a rolling curtain deployment instruction is sent to the rolling curtain device corresponding to the substation terminal screen that does not require operation. The rolling curtain device responds to the rolling curtain deployment instruction to control the rolling curtain sign to unfold to cover the substation terminal screen. Through the assisted monitoring and control of the work ticket, the accuracy of control can be improved, and the rolling curtain device can be accurately controlled according to the work requirements of the work ticket, realizing intelligent and precise control.

[0031] If the switch module on the rolling curtain device is operated by the staff, and it is an operation to unfold the rolling curtain, the rolling curtain signboard is controlled to unfold to cover the substation terminal screen.

[0032] As a non-limiting implementation method, the centralized control platform is specifically used to respond to the rolling curtain device opening trigger operation of the staff and / or detect the input work ticket to determine that the substation terminal screen has ended operation, and when the on-site staff confirms that the operation has ended, send a rolling curtain storage instruction to the rolling curtain device corresponding to the substation terminal screen;

[0033] The rolling curtain device is specifically used to receive a rolling curtain deployment instruction sent by the centralized control platform, and / or to store the rolling curtain sign in response to a staff member's rolling curtain deployment operation on a switch module on the rolling curtain device.

[0034] For example, if the staff performs a storage trigger operation on the centralized control platform, a roller shutter storage instruction is sent to the roller shutter device, and the roller shutter device controls the roller shutter sign to be stored in response to the roller shutter storage instruction to cover the substation terminal screen.

[0035] The work ticket generally marks the start time and end time of the operation. If the operation is completed, the entered work ticket is checked to determine that the substation terminal screen has completed operation, and the on-site staff confirms that the operation is completed, then a rolling curtain storage instruction is sent to the rolling curtain device corresponding to the substation terminal screen, and the rolling curtain device controls the rolling curtain sign to be stored in response to the rolling curtain storage instruction. Through the assistance of work tickets for monitoring and control, the accuracy of control can be improved, and the rolling curtain device can be accurately controlled according to the work requirements of the work ticket, realizing intelligent and precise control.

[0036] If the switch module on the rolling curtain device is operated by the staff, and it is an operation of rolling curtain folding, the rolling curtain signboard is controlled to be folded to cover the substation terminal screen.

[0037] As a non-limiting implementation, the rolling curtain device further includes:

[0038] A controller, used to control the operation of the electric drive module in response to a trigger operation of a staff member and / or a control instruction of the centralized control platform;

[0039] An electric drive module, used to drive the rolling curtain sign to unfold or retract through a motor;

[0040] A synchronous self-check module, used for monitoring the unfolding state or the retracted state of the rolling curtain sign when the motor drives the rolling curtain sign to unfold or retract, and if an abnormal unfolding state or an abnormal retracted state is detected, feedback is given to the controller;

[0041] The controller is also used to control the motor to stop driving the rolling sign to unfold or fold when receiving an abnormal unfolding state or an abnormal folding state, and to send out an alarm signal to alert the staff; wherein the abnormal unfolding state or the abnormal folding state includes: at least one of the rolling sign being stuck, loose, or the roller being stuck.

[0042] As a non-limiting implementation, the synchronous self-checking module further includes a limit detection unit;

[0043] The limit detection unit is used to monitor at least one of whether the roller is rotated into place, whether the rolling sign is moved into place, the rotation time of the roller if it is not rotated into place, and the movement time of the rolling sign if it is not moved into place, so as to determine whether the rolling sign is in an abnormal unfolding state or an abnormal storage state.

[0044] Exemplarily, the limit detection unit can monitor at least one of whether the reel is rotated into place, the length of time the reel has rotated when it has not rotated into place, whether the rolling curtain sign is rotated into place, and the length of time the rolling curtain sign has rotated when it has not rotated into place, so as to determine whether the rolling curtain sign is in an abnormal unfolding state or an abnormal storage state. Exemplarily, if the rolling curtain sign is unfolded into place, the position sensor of the limit detection unit should detect the corresponding first position, and if it is stored into place, the position sensor of the limit detection unit should detect the corresponding second position. If the position sensor is neither the first position nor the second position, it is determined that it has not moved into place. At this time, the length of time the reel has moved is theoretically measured according to the normal moving speed of the rolling curtain sign. It should move into place within t1 time. If it has moved for t2 time and has not moved into place, t2>t1, it is determined that the rolling curtain sign is stuck in the column, and there is an abnormal unfolding state or an abnormal storage state. If the above process occurs during the unfolding process, it is an abnormal unfolding state, and if it occurs during the storage process, it is an abnormal storage state. The same is true for the reel. If the reel rotates into place when driving the roller curtain sign to unfold, the position sensor of the limit detection unit should detect the corresponding third position. If it rotates into place when storing, the position sensor of the limit detection unit should detect the corresponding fourth position. If the position sensor is neither in the third position nor the fourth position, it is determined that it has not rotated into place. At this time, the detection time of the rotation should theoretically be rotated into place within t3 according to the normal movement speed of the reel. If it has moved for t4 time and has not rotated into place, t4>t3, it is determined that the reel is stuck in the column, and there is an abnormal unfolding state or abnormal storage state. If the above process occurs during the unfolding process, it is an abnormal unfolding state, and if it occurs during the storage process, it is an abnormal storage state.

[0045] As a non-limiting implementation, the system further includes: a monitoring device, which is communicatively connected to the centralized control platform;

[0046] The centralized control platform is also used to detect the input work ticket to determine the time period when the rolling curtain signboard of the rolling curtain device corresponding to each substation terminal screen needs to be in the extended state and the time period when it needs to be in the stored state;

[0047] The monitoring device is used to monitor the rolling curtain device corresponding to each substation terminal screen, determine the current state of the rolling curtain signboard of the rolling curtain device in each time period, and send it to the centralized control platform;

[0048] The centralized control platform is also used to compare the current time period and the current status of the rolling curtain signboard of the rolling curtain device with the time period in which the rolling curtain signboard of the rolling curtain device corresponding to each substation terminal screen needs to be in the extended state and the time period in which it needs to be in the stored state, which is pre-determined according to the work ticket, to determine whether the current status of the rolling curtain signboard of the rolling curtain device is compliant. If it is not in compliance with the rules, an alarm signal is issued to alert the staff.

[0049] Exemplarily, if the current state of the rolling curtain signboard of the rolling curtain device in the current time period monitored by the monitoring device is consistent with the state of the rolling curtain signboard of the rolling curtain device corresponding to each substation terminal screen in each time period determined in advance according to the work ticket, then it is determined to be compliant, and if it is inconsistent, it is determined to be non-compliant. For example, it is determined in advance according to the work ticket that the rolling curtain signboard must be in the expanded state in the t5-t6 time period, and the current time period is the t5-t6 time period. If the current state is the expanded state, then it is compliant, and if the current state is the stored state, then it is non-compliant.

[0050] As a non-limiting implementation method, the monitoring device is also used to monitor whether the staff has completed the operation of at least part of the area in the substation terminal screen, and if it is detected that the staff has completed the operation of at least part of the area, a message that the operation of the part of the area is completed is returned to the centralized control platform;

[0051] The centralized control platform issues an alarm to prompt the staff to check the storage state of the rolling curtain sign of the rolling curtain device, and if the rolling curtain sign of the rolling curtain device is in an unfolded state, the rolling curtain sign of the rolling curtain device is controlled to be stored; or,

[0052] The monitoring device monitors whether the rolling curtain sign of the rolling curtain device is in a retracted state, and if not, controls the rolling curtain sign of the rolling curtain device to be retracted.

[0053] For example, there may be multiple operable areas on a substation terminal screen. The staff has completed the operation of some areas, but there may be some areas that have not been completed. The rolling curtain device may mistakenly unfold the rolling curtain signboard due to the completion of the operation of some areas, which will affect the operation of other areas. The monitoring device can monitor that the staff has completed the operation of at least some areas, and there are still some areas that have not been completed. The message of the completion of the operation of some areas is returned to the centralized control platform. The centralized control platform sends an alarm to prompt the staff to check the storage status of the rolling curtain signboard of the rolling curtain device. If the rolling curtain signboard of the rolling curtain device is in the unfolded state, the rolling curtain signboard of the rolling curtain device is controlled to be stored. Or the monitoring device monitors that the staff has completed the operation of at least some areas, and there are still some areas that have not been completed. The message of the completion of the operation of some areas is returned to the centralized control platform. The monitoring device monitors whether the rolling curtain signboard of the rolling curtain device is in the storage state. If not, the rolling curtain signboard of the rolling curtain device is controlled to be stored.

[0054] As a non-limiting implementation method, the centralized control platform is also used to: if it is detected that the staff starts the emergency maintenance function, send a rolling curtain storage instruction to the rolling curtain device corresponding to the substation terminal screen in the emergency state;

[0055] The rolling curtain device is specifically used to receive the rolling curtain storage instruction sent by the centralized control platform and store the rolling curtain sign;

[0056] The centralized control platform is also used to: if it is detected that the staff triggers the shutdown and maintenance function to eliminate the emergency state, send a rolling curtain deployment instruction to the rolling curtain device corresponding to the substation terminal screen in the emergency state;

[0057] The rolling curtain device is specifically used to receive a rolling curtain deployment instruction sent by the centralized control platform and control the deployment of the rolling curtain sign.

[0058] For example, for the protection screen or the measurement and control screen, the cabinet door of the protection screen or the measurement and control screen needs to be opened in the event of an emergency such as tripping, and the centralized control platform is associated with the maintenance function. Once an emergency occurs in the operating status of the protection screen, the staff starts the maintenance function. By starting the maintenance function, the rolling curtain sign corresponding to the protection screen can be temporarily stored, and a quick self-check is also performed during the storage process to ensure that the storage process is fault-free. After the emergency state is eliminated, the centralized control platform will unfold the roller shutter according to the preset program or manual operation of the staff, and close the maintenance function to restore the normal control state of the centralized control platform, so as to avoid the need to open the screen cabinet and be surrounded by the rolling curtain sign and unable to quickly and effectively open the cabinet door, resulting in further expansion of the accident and other events. During the entire emergency handling process, the centralized control platform will record in detail the time of the emergency event, the storage and deployment time of the rolling curtain sign, and the status information of related equipment to provide complete data support for accident analysis.

[0059] As a non-limiting implementation method, the centralized control platform is also used to return to the standby interface and wait for the next instruction if receiving the information returned by the rolling curtain device indicating that the rolling curtain sign is unfolded or stored;

[0060] The centralized control platform is also used to store and back up the current operation data; wherein the current operation data includes at least one of the start time and end time of the rolling shutter device, the moving status of the rolling shutter sign, the operation content and operation time of the staff.

[0063] S220, the rolling curtain device receives a control instruction sent by the centralized control platform, and / or responds to the rolling curtain unfolding operation of the switch module on the rolling curtain device by the staff, and controls the unfolding or folding of the rolling curtain sign.

[0064] Figure 4 A specific implementation flow chart is provided for an embodiment of the present application. When the sign control system of the substation terminal screen is in normal operation, if the roller curtain sign needs to be unfolded, the roller curtain unfolding process is entered; if the roller curtain sign needs to be stored, the roller curtain storage process is entered.
