Description

Technical Field

[0001] This disclosure relates to the field of authorized control technology, and more specifically, to an authorized control circuit and system. Background Technology

[0002] Currently, the power generation process in thermal power plants involves multiple unit generators. When these generators are in use, they need to operate a common system. However, when multiple generators operate the common system simultaneously, conflicts may occur, causing the power generation process to stall or the system to malfunction, posing safety hazards.

[0003] In related technologies, the management and restrictions on equipment and operators are typically implemented. For example, manual management involves manually assigning login authorization accounts to operators of specific unit groups. However, this can degrade the user experience and make it feel cumbersome. For instance, if operators of other unit groups need to perform emergency operations on a shared system, they must contact the authorized unit group's operator for a reset, or the administrator must reassign the unit group's login authorization account. This method still cannot completely prevent multiple unit groups from logging in simultaneously, and it suffers from management chaos, insufficient verification, and cumbersome operations, easily leading to operational errors and security incidents. Summary of the Invention

[0004] The purpose of this disclosure is to provide an authorized control circuit and system.

[0005] To achieve the above objectives, this disclosure provides an authorization control circuit, which includes an OR gate unit, a NOT gate unit, and multiple authorization judgment units, each of which corresponds to an application terminal device.

[0007] The output terminal of the OR gate unit is connected to the input terminal of the NOT gate unit, the first output terminal of each authorization judgment unit is connected to the input terminal of the OR gate unit, and the second output terminal of each authorization judgment unit is used to output a high-level signal or a low-level signal.

[0012] This disclosure also provides an authorization control system, which includes the authorization control circuit and multiple application terminal devices provided in this disclosure, wherein each application terminal device corresponds to an authorization judgment unit in the authorization control circuit.

[0013] Each of the application terminal devices has its signal output terminal connected to the corresponding authorization judgment unit in the authorization control circuit, and the output terminal of each authorization judgment unit in the authorization control circuit is connected to the signal input terminal of its corresponding application terminal device.

[0014] The application terminal device is used to send authorization request instructions or authorization reset instructions.

The signal input terminal of the application terminal device is connected to the second output terminal of the authorization judgment unit corresponding to itself in the authorization control circuit.

[0016] For each of the aforementioned application devices, the first signal output terminal is used to output the authorization request instruction, and the second signal output terminal is used to output the authorization reset instruction. When the application device receives the high-level signal, it unlocks its own permissions, or when it receives the low-level signal, it revokes its own permissions.

[0017] Optionally, the application terminal device includes a first control button and a second control button. The first control button is used to control the application terminal device to send the authorization request instruction to the authorization control circuit, and the second control button is used to control the application terminal device to send the authorization reset instruction to the authorization control circuit.

[0031] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0032] This disclosure provides an authorized control circuit. Figure 1 This is a schematic diagram illustrating the structure of an authorized control circuit according to an exemplary embodiment, such as... Figure 1 As shown, the authorization control circuit 10 includes an OR gate unit 100, a NOT gate unit 200, and multiple authorization judgment units 300, each of which corresponds to an application terminal device.

[0033] The first input terminal of each authorization judgment unit 300 is used to receive the authorization request instruction sent by the corresponding application terminal device, the second input terminal of each authorization judgment unit 300 is used to receive the authorization reset instruction sent by the corresponding application terminal device, and the third input terminal of each authorization judgment unit 300 is connected to the output terminal of the NOT gate unit 200.

[0034] The output terminal of the OR gate unit 100 is connected to the input terminal of the NOT gate unit 200, the first output terminal of each authorization judgment unit 300 is connected to the input terminal of the OR gate unit 100, and the second output terminal of each authorization judgment unit 300 is used to output a high-level signal or a low-level signal.

[0035] The authorization determination unit 300 is configured to output the high-level signal when it receives the authorization request instruction and the NOT gate unit 200 outputs a high-level signal to complete the authorization of the corresponding application terminal device, or to output the low-level signal when it only receives the authorization reset instruction to revoke the authorization of the corresponding application terminal device.

[0036] In one embodiment, any requesting device is authorized to indicate that it can log in and operate the power plant's public system.

[0037] It is worth noting that when the NOT gate unit 200 receives a high-level signal, it will output a low-level signal, and when it receives a low-level signal, it will output a high-level signal; when the OR gate unit 100 receives electrical signals from multiple authorization judgment units 300, it will output a high-level signal if at least one of them is a high-level signal, and it will output a low-level signal if all the received electrical signals are low-level signals.

[0038] In this disclosure, high-level signals can be represented by digital signal "1", and low-level signals can be represented by digital signal "0".

[0039] In one implementation, the application terminal device can be a unit in the power plant. When any unit is authorized, it can log in and operate the power plant's public system. When the authorization of any unit is revoked, the unit will log out of the power plant's public system.

[0040] In one embodiment, the plurality of authorization determination units 300 include a first authorization determination unit and a second authorization determination unit, wherein the first authorization determination unit corresponds to a first unit unit and the second authorization determination unit corresponds to a second unit unit.

[0041] The first authorization judgment unit has the following characteristics: its first input terminal receives authorization request instructions from the first unit; its second input terminal receives authorization reset instructions from the first unit; its third input terminal is connected to the output terminal of the NOT gate unit 200; its first output terminal is connected to the input terminal of the OR gate unit 100; and its second output terminal sends a high-level signal or a low-level signal to the first unit. Similarly, the second authorization judgment unit has the following characteristics: its first input terminal receives authorization request instructions from the second unit; its second input terminal receives authorization reset instructions from the second unit; its third input terminal is connected to the output terminal of the NOT gate unit 200; its first output terminal is connected to the input terminal of the OR gate unit 100; and its second output terminal sends a high-level signal or a low-level signal to the second unit.

[0042] For example, based on the circuit structure in the above embodiment, the authorization process of the unit is explained. When the first unit needs to obtain operating rights to the public system, the operator sends an authorization request instruction to the authorization control circuit 10 through the first unit. The input of the first input terminal of the first authorization judgment unit is 1, and the input of the second input terminal of the first authorization judgment unit is 0. If no unit has been authorized, it means that the outputs of each output terminal of the first authorization judgment unit and the second authorization judgment unit are all 0. Consequently, the inputs of the OR gate unit 100 are all 0, and the output of the OR gate unit 100 is 0. Then the input of the NOT gate unit 200 is 0, and the output of the NOT gate unit 200 is 1. Then the input of the third input terminal of the first authorization judgment unit is 1, and the first authorization judgment unit outputs a high-level signal to complete the authorization of the first unit.

[0043] If the first unit is authorized and the signal output of the OR gate unit 100 is 1, then the signal output by the OR gate unit 100 is 1, and the signal output by the NOT gate unit 200 is 0. At this time, if the operator sends an authorization request command to the authorization control circuit 10 through the second unit, since the output of the NOT gate unit 200 is 0, the signal output by the second authorization judgment unit can only be a low-level signal, and the second unit cannot be authorized.

[0044] If the first unit needs to revoke the obtained authorization, the operator can send an authorization reset command to the authorization control circuit 10 through the first unit. After receiving the authorization reset command, the first authorization judgment unit sets the input of its first input terminal to 0, the input of its second input terminal to 1, and the input of its third input terminal to 0. Then, the first authorization judgment unit outputs a low-level signal to revoke the authorization of the first unit.

[0045] In another embodiment, the authorization determination unit 300 is used to output a high-level signal when it receives an authorization application instruction sent by any application device and no other application device has been authorized, or to output a low-level signal when it receives an authorization reset instruction sent by any application device, in order to obtain authorization from that application device.

[0046] The circuit described above ensures that only one of multiple application devices can be authorized at any given time, thus avoiding security risks caused by operational conflicts between different application devices and improving work efficiency.

[0047] Optionally, see Figure 2As shown, the authorization determination unit 300 includes an AND gate unit 301 and a flip-flop 302. The first input terminal a1 of the AND gate unit 301 is connected to the output terminal of the NOT gate unit 200. The second input terminal a2 of the AND gate unit 301 is used to receive the authorization request instruction. The output terminal of the AND gate unit 301 is connected to the first input terminal b1 of the flip-flop 302. The second input terminal b2 of the flip-flop 302 is used to receive the authorization reset instruction.

[0048] It is worth noting that the input terminals of the authorization judgment unit 300 include the first input terminal a1 of the AND gate unit 301, the second input terminal a2 of the AND gate unit 301, and the second input terminal b2 of the flip-flop 302. The second input terminal a2 of the AND gate unit 301 is the first input terminal of the authorization judgment unit 300, the second input terminal b2 of the flip-flop 302 is the second input terminal of the authorization judgment unit 300, and the first input terminal a1 of the AND gate unit 301 is the third input terminal of the authorization judgment unit 300.

[0049] In one implementation, the signal output by the NOT gate unit 200 is used to indicate whether an application device has been authorized. If no application device has been authorized, the output of the NOT gate unit is a high-level signal; if an application device has been authorized, the output of the NOT gate unit 200 is a low-level signal.

[0050] In addition, both the authorization request instruction and the authorization reset instruction are high-level signals. If the second input terminal of the AND gate unit 301 does not receive a high-level signal "1", it is considered that the input of the second input terminal of the AND gate unit 301 is a low-level signal "0". If the second input terminal of the flip-flop 302 does not receive a high-level signal "1", it is considered that the input of the second input terminal of the flip-flop 302 is a low-level signal "0".

[0051] When both the first input terminal a1 and the second input terminal a2 of the AND gate unit 301 receive a high-level signal, the AND gate unit 301 outputs a high-level signal. When neither the first input terminal a1 nor the second input terminal a2 of the AND gate unit 301 receives a high-level signal, the AND gate unit 301 outputs a low-level signal.

[0052] When the signal received at the first input terminal b1 of the trigger 302 is a high-level signal and the signal received at the second input terminal b2 is a low-level signal, the trigger 302 outputs a high-level signal. When the signal received at the first input terminal b1 of the trigger 302 is a low-level signal and the signal received at the second input terminal b2 is a high-level signal, the trigger 302 outputs a low-level signal. If the first input terminal b1 and the second input terminal b2 of the trigger 302 receive the same type of signal, that is, both are high-level signals or both are low-level signals, the output signal of the trigger 302 remains unchanged.

[0053] For example, the first authorization judgment unit corresponds to the first unit unit. The first authorization judgment unit includes a first AND gate unit and a first flip-flop. After the first unit unit obtains authorization, the first flip-flop outputs a high-level signal. Then, the OR gate unit 100 outputs a high-level signal to the NOT gate unit 200, and the NOT gate unit 200 outputs a low-level signal to the first AND gate unit. Both the first input terminal and the second input terminal of the first AND gate unit receive low-level signals. Then, the first AND gate unit outputs a low-level signal to the first input terminal of the first flip-flop. If the operator does not control the first unit unit to send an authorization reset command, both the first input terminal and the second input terminal of the first flip-flop receive low-level signals. Then, the signal output of the first flip-flop remains unchanged and is still a high-level signal, so that the first unit unit remains in the authorized state and other units cannot obtain authorization.

[0054] Optionally, the trigger is an RS trigger, the first input of the RS trigger is an S (Set) input, and the second input of the RS trigger is an R (Reset) input.

[0055] In one implementation, the RS trigger includes the following operating modes:

[0056] First: When the R input terminal is a high-level signal (1) and the S input terminal is a low-level signal (0), the flip-flop will output a low-level signal (0), that is, the flip-flop is reset.

[0057] Second: When the R input terminal is a low level signal (0) and the S input terminal is a high level signal (1), the flip-flop will output a high level signal (1), that is, the flip-flop is set.

[0058] Third: If both R and S inputs are high (1), the state of the flip-flop will remain unchanged.

[0059] Fourth: If both the R and S inputs are low (0), the state of the flip-flop will remain unchanged.

[0060] Optionally, the trigger is a JK trigger, the first input terminal of the JK trigger is the J input terminal, and the second input terminal of the JK trigger is the K input terminal.

[0061] In one implementation, the JK trigger includes the following operating modes:

[0062] First: Set, that is, when the J input terminal of the JK flip-flop is a high-level signal (1) and the K input terminal (Reset) is a low-level signal (0), the JK flip-flop will output a high-level signal (1).

[0063] Second: Reset, that is, when the input of the J input terminal is a low level signal (0) and the input of the K input terminal is a high level signal (1), the flip-flop will output a high level signal (1).

[0064] Third: Hold, that is, when both the J input terminal and the K input terminal are low level signals (0), the JK flip-flop holds its current state unchanged, that is, the output signal maintains its original value.

[0065] Fourth: Flipping, that is, when the inputs of both the J input terminal and the K input terminal are high level signals (1), the output signal of the flip-flop flips to the opposite value, that is, if the output is 0, it becomes 1, and if it is 1, it becomes 0.

[0066] In one embodiment, to avoid the same application device simultaneously applying for authorization and resetting, the application authorization function of the application device that has already been authorized can be locked, or the application device can be set to send only one of the authorization application instruction and the authorization reset instruction at the same time, so as to avoid operational conflicts caused by the inversion of the output result of the JK flip-flop.

[0067] This disclosure also provides an authorization control system. Figure 3 This is a schematic diagram illustrating the structure of an authorized control system according to an exemplary embodiment. See also... Figure 3 As shown, the authorization control system includes the authorization control circuit 10 and multiple application terminal devices 20 provided in this disclosure, and the application terminal devices 20 correspond one-to-one with the authorization judgment unit 300 in the authorization control circuit 10.

[0068] Each of the application terminal devices 20 has its signal output terminal connected to the corresponding authorization judgment unit 300 in the authorization control circuit. The output terminal of each authorization judgment unit 300 in the authorization control circuit is connected to the signal input terminal of its corresponding application terminal device 20.

[0069] The application terminal device 20 is used to send authorization request instructions or authorization reset instructions.

[0070] In one implementation, the application device 20 can send an authorization request signal or an authorization reset signal to the authorization judgment unit 300 corresponding to itself in the authorization control circuit 10. When an authorization request signal is sent, if the authorization control circuit returns a high-level signal, its own permissions are unlocked, such as the permission of the application device to access and control the public system. If the authorization control circuit 10 returns a low-level signal, it indicates that another application device has been authorized.

[0071] The above system allows for flexible switching of operating permissions between different application devices, avoiding operational conflicts between different application devices and improving work efficiency and security.

[0072] Optionally, see Figure 3 As shown, the signal output terminals of the application terminal device include a first signal output terminal d1 and a second signal output terminal d2. The first signal output terminal d1 of the application terminal device is connected to the first input terminal of the authorization judgment unit corresponding to itself in the authorization control circuit. The second signal output terminal d2 of the application terminal device is connected to the second input terminal of the authorization judgment unit corresponding to itself in the authorization control circuit. The signal input terminal e of the application terminal device is connected to the second output terminal of the authorization judgment unit corresponding to itself in the authorization control circuit.

[0073] For each of the application terminal devices, the first signal output terminal d1 is used to output the authorization request instruction, and the second signal output terminal d2 is used to output the authorization reset instruction. When the application terminal device receives the high-level signal, it unlocks its own permissions, or when it receives the low-level signal, it revokes its own permissions.

[0074] For example, the first application device 20 sends an authorization application instruction to the authorization control circuit 10. If another application device 20 has already obtained authorization, the authorization control circuit 10 will maintain a low-level output signal to the first application device 20, meaning that the first application device 20 cannot obtain authorization. If no other application device 20 has obtained authorization, the authorization control circuit 10 will send a high-level signal to the first application device 20 to unlock the first application device's permissions.

[0075] Optionally, the application terminal device includes a first control button and a second control button. The first control button is used to control the application terminal device to send the authorization request instruction to the authorization control circuit, and the second control button is used to control the application terminal device to send the authorization reset instruction to the authorization control circuit.

[0076] In one embodiment, the first control button and the second control button are physical control buttons on the application terminal device. For each application terminal device 20, when the user presses the first control button, the application terminal device 20 sends an authorization application command to the authorization control circuit 10, that is, it sends a high-level signal to the first input terminal of the authorization judgment unit in the authorization control circuit 10 through the first signal output terminal d1 of the application terminal device 20. When the user presses the second control button, the application terminal device 20 sends an authorization reset command to the authorization control circuit 10, that is, it sends a high-level signal to the second input terminal of the authorization judgment unit 300 in the authorization control circuit 10 through the second signal output terminal d2 of the application terminal device 20.

[0077] Optionally, the application terminal device further includes an operation display page, which is used to display the authorization status of the application terminal device.

[0078] In one embodiment, application device 1 has already obtained authorization. When application device 2 needs to request authorization, the display page of application device 2 will show "Application device 1 has been authorized" to indicate to the operator that authorization cannot be obtained at present. If application device 2 needs to obtain authorization, it can directly connect to the operator of application device 1. And when application device 1 revokes its obtained authorization, the display page of application device 2 will show "No device has obtained authorization". Then application device 2 can send an authorization request command to obtain authorization, thereby improving the working efficiency of the power plant.

[0079] Optionally, both the first control button and the second control button are virtual control buttons within the operation display page.

[0080] After any of the application devices is authorized, the first controller button of the application device is switched to an uncontrollable state and the application device is displayed as authorized.

[0081] In one implementation, see Figure 4 As shown, the "Authorization Request" button is used to send an authorization request command, and the "Reset" button is used to send an authorization reset command. See [link / reference]. Figure 5 As shown, if any application device sends an authorization request instruction through the "Authorization Request" button and obtains authorization, the "Authorization Request" button on the display page of that application device becomes uncontrollable. Through the above method, operation permissions are visualized, and operation permissions are acquired, released, and authorization information is fed back through simple operations on the screen.

[0082] Optionally, the application terminal device further includes a third control button.

[0083] The third control button is used to control the application device to send an emergency authorization request to other authorized application devices.

[0084] In one embodiment, the third control button of the application terminal device can be a non-virtual button or a virtual control button on the display page.

[0085] In one embodiment, if application device 1 has already obtained authorization, and application device 2 urgently needs to obtain system authorization, then the third control button of application device 2 sends an emergency authorization request to all application devices. After receiving the emergency authorization request, the display page of application device 1 will show "Application device 2 needs emergency authorization". After the operator of application device 1 sees this information, he / she can release the authorization obtained by application device 1. After the operators of other application devices see this information, they will not operate the application devices to send authorization request commands, so as to ensure that application device 2 can obtain authorization in a timely manner.

[0086] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0087] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0088] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
