Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms referred to in this application are explained first:
a converter valve: the converter valve is a system with large volume, multiple components and complex structure, mainly comprises components such as a thyristor, a safety and fire prevention system, a lightning arrester, a water cooling system, a saturable reactor, a control and starting unit, a busbar, a switching bus, a shielding cover and the like, and has the main function of realizing AC-DC (rectification) or DC-AC (inversion). The basic valve module consists of a saturable reactor, a thyristor and a control trigger unit, and the core device of the basic valve module is the thyristor. The converter valve operates in complex environments with interwoven multi-physical fields of electricity, magnetism, heat and the like for a long time, and the characteristic of relatively weak operation reliability of the converter valve is determined. The reasons for causing the failure of the converter valve equipment and the fire accident are various, and besides the problems of design and manufacture, the problems also include the local over-temperature of key parts, looseness caused by vibration, water leakage of the parts, insulation failure caused by aging and the like, so that the influence on the whole direct current transmission project is caused, and huge economic loss is brought in serious cases.
Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
The embodiment of the application provides a converter valve safety monitoring system, which is used for carrying out real-time safety monitoring on a converter valve.
As shown in fig. 1, a schematic structural diagram of a converter valve safety monitoring system provided in an embodiment of the present application is shown, where the converter valve safety monitoring system 10 includes: a plurality of wireless sensors 101, a gateway 102, and a monitoring platform 103.
Each wireless sensor is used for respectively acquiring monitoring information of the corresponding converter valve assembly and sending the monitoring information to the gateway; the gateway is used for forwarding the monitoring information to the monitoring platform; and the monitoring platform is used for determining the safety monitoring result of the converter valve according to the monitoring information.
It should be noted that wireless communication is adopted between the wireless sensor and the gateway, and wireless communication may be adopted between the gateway and the monitoring platform, and optical fiber and wired network may also be adopted for communication. The embodiment of the application realizes the wireless monitoring system, so that the sensor can be flexibly deployed, can be used in a plug-and-play manner, and is easy to maintain and replace.
Specifically, the wireless sensor may be disposed on each component of the converter valve to monitor a current state of each component, respectively, and generate corresponding monitoring information. Then, the wireless sensor sends monitoring information to a monitoring platform through a gateway, and the monitoring platform judges whether potential safety hazards exist in each converter valve component according to the obtained monitoring information of each converter valve component, so that relevant operators are timely reminded to take corresponding emergency measures to guarantee the safety of the converter valves. The monitoring information may include, among other things, the temperature, humidity, vibration, pressure, and torque of the converter valve assembly.
The wireless sensor in the embodiment of the application utilizes the battery to supply power, and in order to change the times of the battery by less workers as far as possible, the system provided by the embodiment of the application can adopt a low-power-consumption wide area communication technology so as to greatly reduce the energy consumption of the sensor node, prolong the service life of the sensor and prolong the system maintenance interval.
Specifically, in one embodiment, the wireless sensor may be a wireless sensor without relay functionality; each wireless sensor is in direct communication with the gateway.
It should be noted that, if the wireless sensor with the relay function is used to forward monitoring information to other wireless sensors, the energy consumption of the wireless sensor will be increased.
In the embodiment of the present application, data exchange is performed between the sensor nodes and the gateway through transmitting and receiving radio frequency signals, and each wireless sensor may directly communicate with the gateway, that is, the topology structures of the sensor nodes and the gateway are in a "star" shape as shown in fig. 2. When the distance between the wireless sensor and the current gateway exceeds the communication capacity of the wireless sensor, the gateway can be additionally arranged in the area near the sensor so as to ensure that the monitoring information acquired by the wireless sensor can be normally transmitted.
On the basis of the embodiment, the gateway is not influenced by power supply factors, so that the gateway can be in a monitoring and transmitting state for a long time, the sensor node usually adopts a battery power supply mode, the energy of the sensor node is limited, and the communication of the sensor node needs to adopt a low-power-consumption technology for ensuring the long-time reliable work of the sensor node. As one practical approach, in one embodiment, the wireless sensor comprises an alarm sensor.
The alarm sensor is used for carrying out smoke detection and flame detection on the converter valve, and when smoke or flame of the converter valve is detected, alarm information is sent to the monitoring platform through the gateway.
It should be noted that, in the low power consumption communication technology, for the uplink information sent from the sensor to the gateway, since the gateway is in the constant monitoring state, the sensor node can upload the uplink information at any time according to its own needs. For the downlink information from the gateway, the sensor node can adopt a proper monitoring mode based on the consideration of self power consumption. In the embodiment of the present application, a communication channel through which a sensor transmits a signal and a gateway receives a signal is referred to as an uplink, and a communication channel through which a gateway transmits a signal and a sensor receives a signal is referred to as a downlink.
Specifically, the alarm sensor does not monitor information from the gateway, that is, the alarm sensor node is a node that does not need to acquire downlink information, and only needs to report alarm information when smoke or flame is detected.
Similarly, in one embodiment, the wireless sensor includes a first listening sensor; the first monitoring sensor is used for monitoring a control instruction sent by the monitoring platform in a monitoring period after the monitoring information is uploaded, and acquiring corresponding monitoring information according to the control instruction.
Specifically, the first monitoring sensor monitors a monitoring platform control instruction forwarded by the gateway within a certain time period, and acquires corresponding monitoring information according to the control instruction.
The first monitoring sensor node monitors the downlink information within a period of time after the uplink information is sent, and the current system cannot predict the downlink information transmission of the first monitoring sensor. The first monitoring sensor is suitable for monitoring the pressure and the torque of non-core components (such as a busbar, a switching bus, a shielding case and the like) of the converter valve, and the requirement on time delay of the monitoring information is relatively low.
Similarly, in one embodiment, the wireless sensor includes a second listening sensor; the second monitoring sensor is used for monitoring the control instruction sent by the monitoring platform according to a preset monitoring interval period and acquiring corresponding monitoring information according to the control instruction.
Specifically, the second monitoring sensor node monitors the control instruction once at intervals (monitoring interval period), that is, the current system has a clear downlink information transmission window for the second monitoring sensor. The second monitoring sensor node is a sensor node which has a control requirement on the second monitoring sensor node and has a certain requirement on time delay, and is suitable for monitoring vibration, temperature and current of certain core components (such as a thyristor and the like) of the converter valve.
In order to facilitate comparison and understanding of the communication modes of the three sensors provided in the above embodiments, as shown in fig. 3, a sensor communication window distribution diagram provided in the embodiment of the present application is shown in the figure, where the mode 1) corresponds to the alarm sensor, the mode 2) corresponds to the first monitoring sensor, and the mode 3) corresponds to the second monitoring sensor.
On the basis of the foregoing embodiment, in order to improve the processing efficiency of monitoring information and ensure the safety monitoring efficiency of the converter valve, as an implementable manner, as shown in fig. 4, a schematic structural diagram of another converter valve safety monitoring system provided in the embodiment of the present application is provided, in an embodiment, the monitoring platform 103 includes a network server 1031.
The network server is used for determining a target gateway according to the link quality between the current node and each gateway node and receiving monitoring information forwarded by the target gateway.
It should be noted that the converter valve monitoring system provided in the embodiment of the present application supports simultaneous operation of multiple gateways. When the uplink information is transmitted, for any node of the sensor, if the wireless uplink connection between the node of the sensor and a plurality of gateways is smooth, the gateways can receive the information uploaded by the node of the sensor.
Specifically, since the distances between the gateways and the network server are usually different, in order to ensure the quality of the monitoring information obtained by the monitoring platform, a target gateway may be selected from the gateways according to the link quality between the current network server and the gateways, and the monitoring information forwarded by the target gateway may be received.
Correspondingly, in an embodiment, when the monitoring platform needs to issue a control instruction to the wireless sensor, the network server may select a gateway with an optimal link as a target gateway according to the uplink quality of the sensor node when uploading information last time, and transmit downlink information (control instruction) by using the target gateway.
It should be further noted that the network server is the core of the wireless sensor network, and is used for implementing connection, management and monitoring of the sensor nodes, the gateways and the end user applications.

It should be noted that, in order to ensure the data security of the entire system, the data to be transmitted in the system may be transmitted in the form of ciphertext, and both the encryption operation of the control instruction issued by the monitoring platform and the decryption operation of the monitoring information may be implemented based on the application server.
Specifically, the application server handles the application layer requirements of the network, including upstream data decryption and decoding, downstream data queuing, data encoding, and encryption. The converter valve monitoring system simultaneously provides a network interface for external integration with other external services, and other subsystems in the power system can receive monitoring information of the converter valve based on the network interface so as to realize management of users, organizations, applications and equipment. The control server mainly provides system control services, can interpret and convert data packets received from the application server according to data management standards (such as preset data formats) of the monitoring system, and finally stores the converted data in a database. The database has the functions of high-performance data query, storage and the like.
Because the wireless sensor may have a certain measurement error due to defects such as a manufacturing process, in this embodiment of the application, the control server may calibrate the received monitoring data according to a preset calibration parameter, and store the calibration parameter, the data before calibration, and the data after calibration in the database.
Further, in an embodiment, the control server is further configured to receive system control information input by a user, and send the system control information to the network server through the application server; and the network server controls the wireless sensor according to the system control information.
Specifically, the user may access the control server to implement configuration and control of the system and the sensor node, for example, increase or decrease gateways or nodes in the system, change a measurement time interval, a working mode, transmission power, and the like of the sensor node, and also change downlink transmission power of the gateway.
Specifically, in an embodiment, the monitoring platform further comprises a data visualization server; the data visualization server is used for acquiring the monitoring information in the database and displaying the monitoring information according to the data reading requirement of the user.
Specifically, the data visualization server may specifically display the monitoring data in a data panel interface in the form of a graph, a table, a curve, or the like. The data panel interface can be customized by a user, and extended functions such as alarming, data analysis and the like can be added according to requirements.
