Description

Technical Field

[0001] The present invention relates to the field of one-key sequential control of a substation, and in particular to a substation video double confirmation verification method and system. Background Art

[0002] With the rapid development of power grid construction, the number of substations continues to increase. The development of substations has gone through three stages: conventional substations, intelligent substations, and smart substations. As an important means of substation operation and maintenance, switching operations are mostly still carried out in the traditional way of manual operation one by one, which is far from meeting the development needs of the power system. Traditional switching operations have many disadvantages: complex environment and low efficiency; high risk of misoperation; high cost and difficulty; high risk of personal safety. Under this background, substation sequential control technology was generated. Sequential control is referred to as sequential control. It refers to the technology and operation mode in which a computer automatically completes the control operation of equipment in sequence according to a preset operation sequence in the substation, and completes multiple substation equipment operations at one time.

[0003] However, in the one-button sequential control transformation station that adopts double video confirmation, communication problems between the video host and the verification host and video host access problems often occur. The operation station is troublesome to handle and the risk is high. The forward and reverse isolation of the video host requires repeated configuration modifications and repeated sequential control operations, which increases complexity and reduces work efficiency.

[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0049] Embodiment 1:

[0050] like Figure 1 As shown, a substation video double confirmation verification method includes the following steps:

[0051] S1, independently network the video host verification device, the video host, the forward isolation device and the reverse isolation device to form a verification network;

[0052] S2, setting an interval template for the equipment to be checked in the substation, and generating a switch remote control command according to the interval template;

[0053] S3, in the verification network, the knife switch remote control command is issued to the forward isolation device through the video host verification device, and the forward isolation device forwards the knife switch remote control command to the video host, so that the video host calls the corresponding camera according to the knife switch remote control command;

[0054] S4, observe whether the camera called by the video host correctly goes to the switch position of the device to be verified; if not, the verification fails; if so, execute S5;

[0055] S5, determining whether the video host correctly identifies the current state of the switch of the device to be verified; if not, the verification fails; if so, executing S6;

[0056] S6, setting the current state of the knife switch through the video host to obtain the current state setting signal of the knife switch; transmitting the current state setting signal of the knife switch to the reverse isolation device, using the reverse isolation device to translate the current state setting signal of the knife switch to obtain a double confirmation signal; transmitting the double confirmation signal to the video host verification device, using the video host verification device to automatically compare the double confirmation signal with the required signal to see if they are consistent; if not, the verification fails; if so, the verification passes.

[0057] In the present invention:

[0058] The forward isolation device has the following three functions: 1. Realize secure data exchange between two security zones in a non-network manner, and ensure that the two processing systems inside and outside the security isolation device are not connected at the same time; 2. Comprehensive message filtering and access control based on MAC, IP, transmission protocol, transmission port and communication direction; 3. Prevent penetrating TCP connections: prohibit direct establishment of TCP connections between two application gateways of the intranet and the extranet, and the two network cards inside and outside the isolation device are non-network connected inside the device, and only one-way data transmission is allowed in a physical manner.

[0059] In addition to all the functions of the forward isolation device, the reverse isolation device also has the following functions: the data sending end in the security zone III first signs the data to be sent, and then sends it to the reverse isolation device; after receiving the data, the reverse isolation device verifies the signature, and performs content filtering, validity checking and other processing on the data; and forwards the processed data to the receiving program inside the security zone I / II.

[0060] Based on the characteristics of the above forward isolation device and reverse isolation device, the present invention independently networks the video host verification device, video host, forward isolation device and reverse isolation device, which can avoid communication problems between the video host and the verification host and avoid access problems of the video host.

[0061] In this specific embodiment:

[0062] like Figure 2As shown, in the verification network, the output of the video host verification device is connected to the input of the video host through the forward isolation device, and the output of the video host is connected to the input of the video host verification device through the reverse isolation device.

[0063] In this specific embodiment, S2 is specifically,

[0064] Set up interval templates according to multiple devices to be checked in the substation;

[0065] Acquire the device state files of each device to be calibrated from the substation according to the interval template, and combine the device state files of each device to be calibrated to obtain a device state file sequence;

[0066] Creating a one-key sequential control operation task according to the equipment state file sequence, and retrieving the operation ticket of the one-key sequential control operation task from the substation;

[0067] In the video host verification device, the knife switch remote control command is generated according to the operation ticket.

[0068] Based on the existing one-button sequential control, the present invention sets an interval template, eliminates the repeated configuration of forward and reverse isolation, and directly obtains the equipment status file of each device to be verified from the substation; multiple verification tasks can be added by configuring the interval template once, which improves the operational convenience and work efficiency.

[0069] Preferably, the content in the interval template includes the name, type, interval, interval type and subordinate relationship of the equipment to be calibrated.

[0070] The subordinate relationship refers to the subordinate relationship between the device to be verified and other devices to be verified. The interval template in the present invention takes into account multiple features such as interval, interval type and subordinate relationship, so that multiple verification tasks can be added by configuring the interval template once.

[0071] In this specific embodiment:

[0072] In S5, it is determined whether the video host correctly identifies the current state of the switch of the device to be verified, specifically:

[0073] Obtain a video shot by a camera of the device to be calibrated, extract key frames from the video, and perform state recognition on the key frames to obtain the current state of the switch of the device to be calibrated;

[0074] Acquire the electrical signal of the device to be checked when it is currently working, and calculate the theoretical state of the switch of the device to be checked according to the electrical signal;

[0075] Determine whether the current state of the knife switch of the device to be calibrated is consistent with the theoretical state of the knife switch; if so, determine that the video host correctly identifies the current state of the knife switch of the device to be calibrated; if not, determine that the video host does not correctly identify the current state of the knife switch of the device to be calibrated.

[0076] In S6, the current state setting signal of the knife switch is transmitted from the video host to the reverse isolation and translated by the reverse isolation device. Since the actual switch knife switch of the operating substation does not allow actual position change, the position recognized by the video host is not what we need. It needs to be set on the video host and then transmitted to the reverse isolation device, which translates and generates a double confirmation signal.

[0077] Embodiment 2:

[0078] Based on the above-mentioned substation video double confirmation and verification method, the present invention also provides a substation video double confirmation and verification system.

[0079] like Figure 3 As shown, a substation video double confirmation verification system includes the following modules:

[0080] A networking module, which is used to independently network the video host verification device, the video host, the forward isolation device and the reverse isolation device to form a verification network;

[0081] A command generation module, which is used to set an interval template for the equipment to be checked in the substation and generate a switch remote control command according to the interval template;

[0082] A command issuing module, which is used to issue the knife switch remote control command to the forward isolation device through the video host verification device in the verification network, and the forward isolation device forwards the knife switch remote control command to the video host, so that the video host calls the corresponding camera according to the knife switch remote control command;

[0083] The first verification module is used to observe whether the camera called by the video host correctly goes to the switch position of the device to be verified; if not, the verification fails; if so, the second verification module is executed;

[0084] The second verification module is used to determine whether the video host correctly identifies the current state of the switch of the device to be verified; if not, the verification fails; if so, the third verification module is executed;

[0085] The third verification module is used to set the current state of the knife switch through the video host to obtain the current state setting signal of the knife switch; transmit the current state setting signal of the knife switch to the reverse isolation device, and use the reverse isolation device to translate the current state setting signal of the knife switch to obtain a double confirmation signal; transmit the double confirmation signal to the video host verification device, and use the video host verification device to automatically compare the double confirmation signal with the required signal to see if they are consistent; if not, the verification fails; if so, the verification passes.

[0086] In the present invention:

[0087] The forward isolation device has the following three functions: 1. Realize secure data exchange between two security zones in a non-network manner, and ensure that the two processing systems inside and outside the security isolation device are not connected at the same time; 2. Comprehensive message filtering and access control based on MAC, IP, transmission protocol, transmission port and communication direction; 3. Prevent penetrating TCP connections: prohibit direct establishment of TCP connections between two application gateways of the intranet and the extranet, and the two network cards inside and outside the isolation device are non-network connected inside the device, and only one-way data transmission is allowed in a physical manner.

[0088] In addition to all the functions of the forward isolation device, the reverse isolation device also has the following functions: the data sending end in the security zone III first signs the data to be sent, and then sends it to the reverse isolation device; after receiving the data, the reverse isolation device verifies the signature, and performs content filtering, validity checking and other processing on the data; and forwards the processed data to the receiving program inside the security zone I / II.

[0089] Based on the characteristics of the above forward isolation device and reverse isolation device, the present invention independently networks the video host verification device, video host, forward isolation device and reverse isolation device, which can avoid communication problems between the video host and the verification host and avoid access problems of the video host.

[0090] In this embodiment:

[0091] like Figure 2 As shown, in the verification network, the output of the video host verification device is connected to the input of the video host through the forward isolation device, and the output of the video host is connected to the input of the video host verification device through the reverse isolation device.

[0092] In this embodiment: the command generation module is specifically used to:

[0093] Set up interval templates according to multiple devices to be checked in the substation;

[0094] Acquire the device state files of each device to be calibrated from the substation according to the interval template, and combine the device state files of each device to be calibrated to obtain a device state file sequence;

[0095] Creating a one-key sequential control operation task according to the equipment state file sequence, and retrieving the operation ticket of the one-key sequential control operation task from the substation;

[0096] In the video host verification device, the knife switch remote control command is generated according to the operation ticket.

[0097] Based on the existing one-button sequential control, the present invention sets an interval template, eliminates the repeated configuration of forward and reverse isolation, and directly obtains the equipment status file of each device to be verified from the substation; multiple verification tasks can be added by configuring the interval template once, which improves the operational convenience and work efficiency.

[0098] Preferably, the content in the interval template includes the name, type, interval, interval type and subordinate relationship of the equipment to be calibrated.

[0099] The subordinate relationship refers to the subordinate relationship between the device to be verified and other devices to be verified. The interval template in the present invention takes into account multiple features such as interval, interval type and subordinate relationship, so that multiple verification tasks can be added by configuring the interval template once.

[0100] In this specific embodiment:

[0101] In the second verification module, whether the video host correctly identifies the current state of the switch of the device to be verified is specifically:

[0102] Obtain a video shot by a camera of the device to be calibrated, extract key frames from the video, and perform state recognition on the key frames to obtain the current state of the switch of the device to be calibrated;

[0103] Acquire the electrical signal of the device to be checked when it is currently working, and calculate the theoretical state of the switch of the device to be checked according to the electrical signal;

[0104] Determine whether the current state of the knife switch of the device to be calibrated is consistent with the theoretical state of the knife switch; if so, determine that the video host correctly identifies the current state of the knife switch of the device to be calibrated; if not, determine that the video host does not correctly identify the current state of the knife switch of the device to be calibrated.

[0105] In the third verification module, the current state setting signal of the knife switch is transmitted from the video host to the reverse isolation and translated by the reverse isolation device. Since the actual switch knife switch of the operating substation does not allow actual position change, the position recognized by the video host is not what we need. It needs to be set on the video host and then transmitted to the reverse isolation device, which translates it to generate a double confirmation signal.

[0106] The present invention discloses a substation video double confirmation verification method and system, which independently networks a video host verification device, a video host, a forward isolation device and a reverse isolation device, thereby avoiding communication problems between the video host and the verification host and avoiding access problems of the video host; at the same time, according to the knife switch remote control command generated by the interval template, multiple equipment verification tasks can be added in one configuration, thereby avoiding the trouble of one equipment verification requiring one forward and reverse isolation configuration, thereby improving work efficiency; in addition, in the verification process, by observing whether the camera called by the video host correctly goes to the knife switch position corresponding to the equipment to be verified, judging whether the video host correctly identifies the current state of the knife switch of the equipment to be verified, and using the video host verification device to automatically compare whether the double confirmation signal is consistent with the required signal, these three verification processes improve the verification accuracy of the video double confirmation and ensure the smooth implementation of the one-key sequential control transformation.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
