The nuclear island comprises a central device 101, a communication conversion device 102, a target monitoring device 103 and an intranet server 104, and a security device 105. The central equipment 101 can be a master control PLC (Programmable Logic Controller ), namely a master station of a ring crane control system PLC, and is used for monitoring the running state of each ring crane in the nuclear island; the communication conversion device 102 is communicated with the central equipment 101 and the target monitoring equipment 103, and is provided with an RS-232 (Recommand Standard-232, recommended standard-232) interface or an RS-485 interface, and is used for converting ring crane fault data sent by the central equipment 101 and then forwarding the ring crane fault data to the target monitoring equipment 103; the target monitoring device 103 may be an industrial computer or a debugging computer corresponding to the fault ring crane, and the target monitoring device 103 may be further communicated with the intranet server 104 through the intranet, and is used for reading PLC data and status sent by the central device 101, namely ring crane fault data, and sending the ring crane fault data to the intranet server 104 through the intranet; the intranet server 104 is operated with an intranet database, the intranet database is used for storing ring crane fault data, and the intranet database can be remotely accessed by trusted security equipment 105 through the intranet.
It will be appreciated that there are several monitoring devices within the nuclear island, typically each corresponding to a ring crane, and the target monitoring device 102 described above is merely an example.
The security device 105 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices. Intranet server 104 may be implemented as a stand-alone server or as a cluster of servers.
At present, when a ring crane in a nuclear island breaks down, a professional engineer is required to go to the nuclear island site to check the ring crane fault, and under the condition that the professional engineer cannot arrive at the nuclear island site in time, the ring crane fault checking efficiency cannot be ensured.
In order to solve the above problem, in one embodiment, as shown in fig. 2, there is provided a fault handling method applied to an in-core island monitoring device, including the steps of:
s201, ring crane fault data of the fault ring crane are obtained.
The nuclear island is a common name of a nuclear reactor in a containment of a nuclear power plant and various systems related to the reactor, the ring crane is heavy lifting equipment commonly used in the nuclear island, and each ring crane is provided with a corresponding monitoring device which can be an industrial computer or a debugging computer.
When any ring crane in the nuclear island fails, the monitoring equipment corresponding to the ring crane acquires ring crane failure data of the failed ring crane from central equipment in the nuclear island. The central equipment can be the only master control PLC in the nuclear island, namely a main station of the ring crane control system PLC, is responsible for monitoring the running state of each ring crane in the nuclear island, and safely transmits ring crane fault data of the fault ring crane to monitoring equipment corresponding to the fault ring crane when any ring crane is monitored to have faults. The ring crane fault data may include, but is not limited to, base information and operating conditions of the components of the failed ring crane.
S202, the ring crane fault data are sent to the corresponding intranet servers, so that the intranet servers can store the ring crane fault data in the intranet database.
The intranet server is a local area network server in the nuclear island, an intranet database for storing various monitoring data in the nuclear island is operated on the intranet server, the intranet is a special network paved in the nuclear power station, and the intranet is a special 4G network.
The monitoring equipment sends ring hanging fault data to the intranet server through the intranet, so that the ring hanging fault data are stored in an intranet database on the intranet server, and the intranet database can realize ring hanging fault data sharing inside and outside the nuclear island. The ring crane fault data in the intranet database are used for the ring crane maintenance party outside the nuclear island to access through the intranet based on the held safety equipment so as to conduct fault troubleshooting on the fault ring crane.
It can be understood that the intranet server has specific security measures, and is only accessed by internal personnel trusted by the nuclear island, such as a ring lifting wiener outside the nuclear island. When the ring crane maintenance party cannot timely arrive at the nuclear island site to check the fault ring crane, the ring crane fault data can be checked by remotely accessing an intranet database through the intranet. Optionally, the security device held by the ring hoisting maintenance party outside the nuclear island is the nuclear island trust device.
Optionally, a USB-4G (Universal Serial Bus-the 4th generation mobile communication technology, universal serial bus-fourth generation mobile communication technology) module dedicated for the core island is inserted on the monitoring device, so that the monitoring device accesses the intranet server, and further the monitoring device can respond to the data writing instruction to write the received fault ring crane data into the intranet database, or the monitoring device automatically writes the fault ring crane data into the intranet database.
Therefore, the ring crane maintenance party outside the nuclear island can remotely check the fault ring crane data under the condition of not going to the nuclear island site, and further perform fault investigation on the fault ring crane based on the fault ring crane data, so that the delay of the nuclear island construction process is avoided.
According to the scheme, the monitoring equipment in the nuclear island acquires ring crane fault data of the fault ring crane, and then the ring crane fault data are sent to the corresponding intranet server, so that the intranet server stores the ring crane fault data in the intranet database; the ring crane fault data in the intranet database are used for the ring crane maintenance party outside the nuclear island to access through the intranet based on the held safety equipment so as to conduct fault troubleshooting on the fault ring crane. According to the method, the ring crane fault data for fault investigation are written into the special intranet database of the nuclear island by the monitoring equipment in the nuclear island, the ring crane fault data are safely transmitted to the outside of the nuclear island, the ring crane fault data can be accessed by the ring crane maintenance party of the outer ring of the nuclear island through the intranet, the fault investigation is carried out on the ring crane, the fault investigation efficiency is improved by a remote fault investigation mode, the intranet database is in access authority, only the safety equipment is opened and authorized, the ring crane fault data in the nuclear island can be prevented from being leaked, and the requirement of the safety of the nuclear island is met.
As an alternative manner in this embodiment, ring crane fault data of the fault ring crane sent by the central device in the nuclear island through the physical unidirectional transmission path may be received.
Specifically, the communication path between the central equipment and the monitoring equipment is a physical unidirectional transmission path, namely the monitoring equipment can only receive the data sent by the central equipment and can not send the data to the central equipment, which is realized based on physical hardware and has higher reliability.
For example, only the transmitting port of the center device is connected, but not the receiving port of the center device, so that the center device cannot receive the data transmitted by the monitoring device without opening the receiving port of the center device, thereby realizing physical unidirectional transmission.
Therefore, the central equipment is responsible for monitoring the running state of each ring crane in the nuclear island, the monitoring equipment does not participate in ring crane control, the central equipment sends ring crane fault data to the corresponding monitoring equipment through a physical unidirectional transmission path, the safety isolation of the central equipment in the nuclear island can be effectively ensured, and even if any monitoring equipment in the nuclear island breaks down, the central equipment cannot be affected.
In order to stably transmit ring fault data, in one embodiment, the physical unidirectional transmission path includes a communication conversion device, and the central device and the communication conversion device are in unidirectional transmission, as shown in fig. 3, S201 may include:
s301, receiving two paths of differential signals sent by a communication conversion device.
The two paths of differential signals are obtained by converting ring crane fault data sent by the central equipment through a communication conversion device.
The communication conversion device can be a module which is communicated with the central equipment, such as an RS-232 conversion module or an RS-485 conversion module, and a communication path between the central equipment and the communication conversion device is a physical unidirectional transmission path.
The RS-232 conversion module is provided with an RS-232 full duplex receiving and transmitting interface, is suitable for point-to-point communication scenes, adopts common mode level coding for signals, and generally needs three lines of Rxd (receiving line)/Txd (transmitting line)/Gnd (ground line) connection. The RS-485 conversion module is provided with an RS-485 half-duplex receiving and transmitting interface, is commonly used for a modbus physical layer, adopts differential level coding for signals, adopts a pair of twisted pair on-site wiring, and has good anti-interference performance.
The communication conversion device receives ring crane fault data sent by the central equipment to the monitoring equipment, and converts the ring crane fault data into two paths of differential signals for transmission in order to stably transmit the ring crane fault data. Correspondingly, the monitoring equipment receives two paths of differential signals sent by the communication conversion device.
S302, loop crane fault data of the fault loop crane are determined according to the difference value between the two paths of differential signals.
The two paths of differential signals are signals with equal transmission variation amplitude and opposite phases, the environmental noise and the interference signals can affect the two paths of differential signals at the same time, and the monitoring equipment responds to the difference value between the two paths of differential signals, so that ring crane fault data transmitted after being converted into the two paths of differential signals has stronger anti-interference capability.
Optionally, when the two paths of differential signals are RS-485 differential signals, two paths of RS-485 buses exist between the communication conversion device and the monitoring equipment, and the two paths of differential signals are respectively transmitted to the monitoring equipment based on the two paths of RS-485 buses.
Further, the monitoring device responds to the difference value between the two paths of differential signals to determine ring crane fault data of the corresponding fault ring crane.
In an alternative embodiment, the communication interface of the central device and the communication interface of the communication conversion device are both COM3 interfaces, and the connection line between the receiving port of the communication interface of the central device and the transmitting port of the communication interface of the communication conversion device is in a communication prohibition state.
For example, the center device is realized based on an AC800M controller, and is provided with a COM3 interface capable of supporting unidirectional transmission, and the center device has bidirectional communication capability under the condition that the COM3 interface adopts an RS-232 communication mode, and can use three connection wires of RXD/TXD/GND, namely a receiving wire, a transmitting wire and a ground wire. The port corresponding to the receiving line is the receiving port, and the port corresponding to the transmitting line is the transmitting port.
As shown in fig. 4, in order to implement a physical unidirectional transmission path between the center device and the communication conversion device, only a transmitting line (TXD) and a ground line (GND) of a COM3 interface of the center device are connected, and a receiving line (RXD) of the COM3 interface of the center device is not connected, so that ring crane fault data can only be sent out from the COM3 interface, and the COM3 interface cannot receive any returned data, thereby blocking any form of external data from being input to the center device, and ensuring safety isolation of the center device.
Optionally, the driver corresponding to the receiving port of the communication interface of the central device is configured to prohibit the call.
For example, the center device is realized based on an AC800M controller, and is provided with a COM3 interface capable of supporting unidirectional transmission, the COM3 interface loads a modbus rtu protocol, only a transmitting module is called in serial port driving of the COM3 interface, a receiving module is forbidden to be called, the COM3 interface is locked into a mode of only transmitting and not receiving, and a physical unidirectional transmission path between the center device and a communication conversion device is further ensured.
In the embodiment, the central equipment sends the ring crane fault data to the corresponding monitoring equipment through the communication conversion device, and the communication conversion device is used for converting the ring crane fault data into two paths of differential signals for transmission, so that the stability and reliability of data transmission are effectively improved, and the ring crane fault data can be prevented from being influenced by environmental noise and other interference signals; in addition, the physical unidirectional transmission path is arranged between the central equipment and the communication conversion device, so that the physical unidirectional transmission between the central equipment and the monitoring equipment can be realized, and the introduction of the communication conversion device not only improves the transmission quality of the ring crane fault data, but also ensures the safety isolation of the central equipment.
In order to improve the security of the monitoring device and avoid intrusion of external data into the monitoring device corresponding to each ring crane, in one embodiment, as shown in fig. 5, the step S202 may include:
s501, performing redundancy verification on ring crane fault data.
The ring crane fault data received by the monitoring equipment comprise check bits, and the check bits are check values obtained by calculating the original ring crane fault data by adopting a specific algorithm. And the monitoring equipment performs redundancy verification on the ring crane fault data based on the check value. The redundancy verification may be performed by LRC (Longitudinal Redundancy Check ) or CRC (Cyclic Redundancy Check, cyclic redundancy check), which is not limited in this embodiment.
Optionally, the monitoring device performs redundancy verification on the two paths of differential signals. For example, CRC is adopted for checking, the communication conversion device performs polynomial calculation on the original ring crane fault data, and the obtained check value is attached to a data frame of the ring crane fault data, so that the monitoring device determines the check value from the two paths of differential signals and checks the check value, or directly checks the two paths of differential signals.
S502, if the redundancy verification is passed, ring crane fault data are sent to the corresponding intranet server.
And if the redundancy verification is passed, sending the ring crane fault data to the corresponding intranet server. The redundancy verification indicates that no error exists in the transmission process of the ring crane fault data, and then the monitoring equipment uploads the ring crane fault data to the intranet server through the intranet so that the intranet server can store the ring crane fault data in the intranet database.
The intranet database can be accessed only through the exclusive intranet of the nuclear power station, and the monitoring equipment in the nuclear island and the safety equipment outside the nuclear island can check ring crane fault data in the intranet database under the condition of being authorized by open access.
In an alternative embodiment, the intranet database prohibits the security device from writing data through the intranet.
In other words, the security device outside the nuclear island can only access the intranet database through the intranet to check the ring crane fault data in the intranet database, and the security device does not have the authority of data writing and cannot change the monitoring data in the intranet database.
S503, when the redundancy verification is not passed, the ring crane fault data is forbidden to be sent to the corresponding intranet server.
If the redundancy verification is not passed, the error of the ring crane fault data in the transmission process is indicated, the received ring crane fault data is forbidden to be sent to the intranet server for storage, and meanwhile, the ring crane fault data is discarded and retransmission is requested.
In the embodiment, redundancy verification is performed on ring crane fault data, if the redundancy verification is passed, the ring crane fault data are sent to a corresponding intranet server, so that the ring crane fault data stored in an intranet database can be ensured to be accurate, and the situation that the ring crane fault data are checked by a ring crane maintenance party outside a nuclear island to influence fault investigation of a fault ring crane is avoided; in addition, the ring crane fault data in the intranet database can only be checked by the ring crane lifting maintenance party of the outer ring of the nuclear island based on the held safety equipment, and the intranet database cannot be written with data, so that the safety of the intranet database is effectively ensured.
In one embodiment, an alternative example of a fault handling method is provided, as shown in a system architecture diagram shown in fig. 6 and a flowchart shown in fig. 7, a central device in a nuclear island sends ring crane fault data to a communication conversion device, and then the communication conversion device converts the ring crane fault data into two paths of differential signals and sends the two paths of differential signals to a monitoring device, and further, the monitoring device sends the ring crane fault data to an intranet server running an intranet database, so that a security device outside the nuclear island can access the intranet database from the intranet server to view the ring crane fault data. Specifically, the fault handling method includes the following steps:
