Description

Technical Field

[0001] The present invention relates to the technical field of power system communication and equipment simulation detection, and in particular to a FTU terminal communication module simulation detection and analysis device and method. Background Art

[0002] In recent years, the National Energy Administration and power grid companies have successively issued a series of action plans or documents on the upgrading and transformation of distribution networks, clearly stating that distribution automation will be gradually promoted and applied nationwide. In order to ensure that the distribution automation system can achieve reliable monitoring, protection, control and distribution management under normal operation and various accident conditions, how to carry out systematic testing has become an urgent problem facing the industry. Distribution automation testing usually refers to a professional test based on communication network technology, which collects and sorts out online / offline data, user data, grid topology data, etc. of distribution network equipment under various expected conditions to analyze and determine whether distribution automation can operate normally and reliably.

[0003] At present, the detection of distribution automation system is mainly carried out by using relay protection tester to carry out offline relay simulation test, which mainly includes the following categories: First, only for distribution terminal equipment, electromagnetic compatibility and three remote functions detection are carried out; second, only for the main station, the main station injection method is used with the standard model library to carry out detection; third, combining the first two categories, the distribution terminal equipment and the main station detection are carried out separately.

[0004] Although the above-mentioned types of testing have solved basic problems such as electromagnetic compatibility, functional testing and three-remote detection between the distribution master station and the terminal, the effectiveness and efficiency of the testing are subject to the following factors.

[0005] 1) There are a large number of distribution automation terminals, and a large number of devices are installed outdoors. Equipment damage and communication interruption often occur.

[0006] 2) Due to the reconstruction, expansion and adjustment of the operation mode of the distribution network lines, the interconnecting switches are often switched.

[0007] 3) The distribution automation terminal communicates with the master station by establishing a TCP protocol long connection. In order to maximize resource utilization, the mobile base station will optimize the management of the long connection and recycle TCP connection resources according to the resource management algorithm, resulting in frequent offline operations of the terminal. Summary of the invention

[0008] In view of the above-mentioned problems, the present invention is proposed.

[0009] Therefore, the technical problem solved by the present invention is: simulating the communication situation of the terminal communication module at the location where the terminal frequently drops offline, recording the communication bottom layer logs such as the simulated communication module offline time period, signal strength, cell switching, etc., analyzing the simulated communication module logs, comparing the terminal offline situation, finding the root cause of the frequent terminal offline, and providing improvement basis and strategy for improving the terminal online rate;

[0010] During the construction, installation and design phase of the distribution network automation terminal, the instrument can be used to scientifically select sites to avoid blindly selecting installation locations.

[0011] To solve the above technical problems, the present invention provides the following technical solutions: a FTU terminal communication module simulation detection and analysis device, which comprises the following steps:

[0012] Power module, CPU, communication port, human-machine interface HMI, and debugging and communication interface.

[0013] The communication port is divided into a communication port 1 and a communication port 2.

[0014] As a preferred solution of the FTU terminal communication module simulation detection and analysis device described in the present invention, the power supply module is responsible for supplying power to the FTU terminal communication module simulation detection and analysis device.

[0015] The output and input ports in the CPU are connected to the remote signal output circuit and the remote control input circuit respectively.

[0016] The communication port is responsible for data interaction between the CPU and the human-machine interface.

[0017] The human-machine interface HMI controls the output port of the CPU, simulates the remote signal change and SOE signal to the feeder monitoring terminal, records the event information of the input port of the CPU, and determines the correctness of the remote control operation of the feeder terminal.

[0018] Another object of the present invention is to provide a FTU terminal communication module simulation detection and analysis method, which can automatically record and analyze the underlying communication log during the communication process, thereby solving the problem that the existing FTU terminal communication module lacks effective monitoring and diagnostic tools during the communication process.

[0019] In order to solve the above technical problems, the present invention provides the following technical solutions: a FTU terminal communication module simulation detection and analysis method, comprising:

[0020] Relevant parameters are set through the configuration interface of the FTU terminal communication module simulation detection and analysis device.

[0021] The simulation communication module is started through the control interface of the FTU terminal communication module simulation detection and analysis device or a remote command to start the simulation communication.

[0022] The FTU terminal communication module simulation detection and analysis device automatically records the underlying communication log during the communication process.

[0023] Analyze the exported communication logs to find out the reasons why the terminal is disconnected or frequently disconnected.

[0024] As a preferred solution of the FTU terminal communication module simulation detection and analysis method described in the present invention, wherein: the setting of relevant parameters is consistent with the communication parameters of the FTU terminal communication module simulation detection and analysis device and the main station.

[0025] As a preferred solution of the FTU terminal communication module simulation detection and analysis method described in the present invention, the starting of simulation communication includes: the FTU terminal communication module simulation detection and analysis device is in a listening state, waiting for a connection request, and after the connection request is sent by the main station, a TCP connection is established. When the FTU terminal communication module simulation detection and analysis device receives a U-formatted message STARTDT, the FTU terminal communication module simulation detection and analysis device responds with a STARTDT confirmation message and starts transmitting data.

[0026] As a preferred solution of the FTU terminal communication module simulation detection and analysis method described in the present invention, the underlying communication log includes the offline time period, signal strength, signal-to-noise ratio, packet loss rate and cell switching.

[0027] As a preferred solution of the FTU terminal communication module simulation detection and analysis method described in the present invention, wherein: a comprehensive signal quality assessment is performed based on the underlying communication log, including recording when the signal strength is lower than a specific threshold and the signal-to-noise ratio is less than a specific value as a weak signal event, and recording the packet loss rate of the signal quality before each message retransmission, wherein if the signal quality is a weak signal and the packet loss rate is less than the limit value, it is determined that there is channel congestion.

[0028] The offline time period is obtained based on the offline judgment mechanism.

[0029] The offline judgment mechanism includes that the core unit of the FTU terminal communication module simulation detection and analysis device communicates with the wireless module through serial port 232. The communication process is that the core unit sends the message to the wireless module, and the wireless module transmits it to the main station front server through the GPRS wireless network through the communication base station. The main station front server sends the message to the wireless module, and the wireless module forwards it to the core unit.

[0030] The FTU terminal communication module simulation detection and analysis device sends application messages or heartbeat messages to the wireless module. If the terminal does not receive a reply message from the master station within 30 seconds, the terminal will resend the message. If the master station still does not reply after resending three times, the device will actively disconnect from the master station and wait for the next reconnection.

[0031] Count the total number of disconnections within 24 hours and distinguish between short disconnections and long disconnections.

[0032] The short-term disconnection means that the disconnection time is less than 5 minutes, and the long-term disconnection means that the disconnection time is greater than or equal to 5 minutes.

[0033] If the proportion of short-term disconnections exceeds 50%, it will be recorded as a frequent withdrawal event.

[0034] As a preferred solution of the FTU terminal communication module simulation detection and analysis method described in the present invention, the analysis of the exported communication log includes comparing the signal differences of different devices at the same time and the same coordinates, evaluating the signal quality and online rate of different installation positions, and selecting the optimal installation point.

[0035] The master station is set to resend three times, with an interval of 30 seconds each time. If no reply message is received from the device for three times, it is determined that the device is offline and the master station will re-initiate the communication connection.

[0036] If the number of disconnections per day is ≥ 3 times, it can be considered as frequent disconnections.

[0037] The searching for the reasons for the terminal disconnection or frequent switching on and off includes: if the number of short-term disconnections exceeds 50% and there is signal congestion, then determining that the reason for the terminal disconnection or frequent switching on and off is channel congestion.

[0038] If the packet loss rate between the device and the master station exceeds the specified value and there is no channel congestion, it is determined that the communication between the device and the master station is unstable.

[0039] If the packet loss rate does not exceed the limit and the network is not congested during the period when the device is offline from the master station, but the load of the device is higher than the specified load, it is judged that frequent reconnections are caused by the degradation of device performance.

[0040] When there is channel congestion, the wireless resource allocation algorithm is adjusted to dynamically allocate devices to different frequency bands. The transmission rate of the device is dynamically adjusted according to the current load of the network and the channel quality. Additional relay nodes or base stations are deployed to increase the capacity and coverage of the wireless network.

[0041] When there is unstable communication between the device and the master station, strengthen the robustness of the communication protocol, set a reasonable retry mechanism, optimize the ACK / NACK feedback mechanism in the protocol, increase the number and interval of retransmissions, and implement a fast reconnection mechanism.

[0042] When device performance degrades, strengthen the device's cooling system.

[0043] A computer device includes a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the steps of the above-mentioned FTU terminal communication module simulation detection and analysis method are implemented.

[0044] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the above-mentioned FTU terminal communication module simulation detection and analysis method.

[0045] Beneficial effects of the present invention:

[0046] (1) When planning the line, it is impossible to predict in advance whether the signal strength of the distribution automation switch installation point meets the online rate requirements. This device can be used to scientifically select the site to avoid blindly selecting the installation location, which may result in the expected planned investment effect not being achieved due to problems such as weak signals after the equipment is built.

[0047] (2) The device can be powered by a lithium battery, simulates the communication service data communication between the terminal communication module and the main station, and can be installed outdoors for a long time to perform communication link and signal strength detection.

[0051] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0052] Example 1, reference Figure 1 , is an embodiment of the present invention, and provides a FTU terminal communication module simulation detection and analysis device, which is characterized by:

[0053] Power module, CPU, communication port, human-machine interface HMI, and debugging and communication interface.

[0054] The communication port is divided into communication port 1 and communication port 2.

[0055] The power module is responsible for supplying power to the FTU terminal communication module simulation detection and analysis device.

[0056] The output and input ports in the CPU are connected to the remote signal output circuit and the remote control input circuit respectively.

[0057] The communication port is responsible for data interaction between the CPU and the human-machine interface.

[0058] The human-machine interface HMI controls the output port of the CPU, simulates the remote signal change and SOE signal to the feeder monitoring terminal, records the event information of the CPU input port, and determines the correctness of the remote control operation of the feeder terminal.

[0059] Example 2, reference Figure 2 , as an embodiment of the present invention, provides a method for simulating detection and analysis of a FTU terminal communication module, characterized in that:

[0060] S1: Set relevant parameters through the configuration interface of the FTU terminal communication module simulation detection and analysis device.

[0061] Set the relevant parameters so that the communication parameters of the FTU terminal communication module simulation detection and analysis device are consistent with those of the main station.

[0062] S2: Start the simulation communication module through the control interface of the FTU terminal communication module simulation detection and analysis device or a remote command to start the simulation communication.

[0063] The start of simulation communication includes that the FTU terminal communication module simulation detection and analysis device is in a listening state, waiting for a connection request. After the connection request is sent by the master station, a TCP connection is established. When the FTU terminal communication module simulation detection and analysis device receives the U-formatted message STARTDT, the FTU terminal communication module simulation detection and analysis device responds with a STARTDT confirmation message and starts transmitting data.

[0064] Furthermore, for various command messages from the master station, including: general call, clock synchronization, telemetry, telesignaling, remote control and other functions, input validity checks are performed and responses are given to the master station.

[0065] Furthermore, the normal process of the communication connection between the master station and the terminal is security authentication-encryption authentication-initialization-initialization general call-clock synchronization-heartbeat.

[0066] When simulating communication, the device enters the field debugging mode. This operation mode does not use an operating system, and processes each task priority in a cyclic manner in order. The device presents the content obtained from each task on the human-machine interface, including telemetry acquisition, telesignaling acquisition, remote control output, real-time clock area, and telemetry, telesignaling, and remote control messages in accordance with the 101 / 104 protocol. The device in wireless communication mode can complete basic functions such as "three remote" functions, relay protection, and SOE event sequence recording. After the device is connected to the distribution network master station through wireless communication, it can upload the voltage and current collected by the A / D conversion circuit, the switch state collected by the relay drive circuit, and accept the remote control command sent by the distribution network master station to perform corresponding remote control return and execution operations. At the same time, the device can receive the time synchronization command from the distribution network master station to achieve clock synchronization with the distribution network master station.

[0067] S3: The FTU terminal communication module simulation detection and analysis device automatically records the underlying communication log during the communication process.

[0068] The underlying communication log includes information such as disconnection time period, signal strength, signal-to-noise ratio, packet loss rate, and cell switching.

[0069] Export the communication log via the interface / storage device provided by the device.

[0070] Comprehensive signal quality assessment is performed based on the underlying communication log, including recording weak signal events when the signal strength is below a specific threshold and the signal-to-noise ratio is less than a specific value, and recording the packet loss rate of the signal quality before each message retransmission. If the signal quality is weak and the packet loss rate is less than the limit value, it is determined that there is channel congestion.

[0071] The offline time period is obtained based on the offline judgment mechanism.

[0072] The offline judgment mechanism includes that the core unit of the FTU terminal communication module simulation detection and analysis device communicates with the wireless module through serial port 232. The communication process is that the core unit sends the message to the wireless module, and the wireless module transmits it to the main station front server through the GPRS wireless network through the communication base station. The main station front server sends the message to the wireless module, and the wireless module forwards it to the core unit.

[0073] The FTU terminal communication module simulation detection and analysis device sends application messages or heartbeat messages to the wireless module. If the terminal does not receive a reply message from the master station within 30 seconds, the terminal will resend the message. If the master station still does not reply after resending three times, the device will actively disconnect from the master station and wait for the next reconnection.

[0074] Count the total number of disconnections within 24 hours and distinguish between short disconnections and long disconnections.

[0075] A short disconnection time is less than 5 minutes, and a long disconnection time is greater than or equal to 5 minutes.

[0076] If the proportion of short-term disconnections exceeds 50%, it will be recorded as a frequent withdrawal event.

[0077] S4: Analyze the exported communication logs to find out the reasons why the terminal is disconnected or frequently disconnected.

[0078] The analysis of the exported communication logs includes comparing the signal differences of different devices at the same time and coordinates, evaluating the signal quality and online rate of different installation locations, and selecting the optimal installation point.

[0079] The master station is set to resend three times, with an interval of 30 seconds each time. If no reply message is received from the device for three times, it is determined that the device is offline and the master station will re-initiate the communication connection.

[0080] If the number of disconnections per day is ≥ 3 times, it can be considered as frequent disconnections.

[0081] Finding the reasons for the terminal disconnection or frequent switching on and off includes: if the number of short-term disconnections exceeds 50% and there is signal congestion, it is determined that the reason for the terminal disconnection or frequent switching on and off is channel congestion.

[0082] If the packet loss rate between the device and the master station exceeds the specified value and there is no channel congestion, it is determined that the communication between the device and the master station is unstable.

[0083] If the packet loss rate does not exceed the limit and the network is not congested during the period when the device is offline from the master station, but the load of the device is higher than the specified load, it is judged that frequent reconnections are caused by the degradation of device performance.

[0084] When there is channel congestion, the wireless resource allocation algorithm is adjusted to dynamically allocate devices to different frequency bands. The transmission rate of the device is dynamically adjusted according to the current load of the network and the channel quality. Additional relay nodes or base stations are deployed to increase the capacity and coverage of the wireless network.

[0085] When there is unstable communication between the device and the master station, strengthen the robustness of the communication protocol, set a reasonable retry mechanism, optimize the ACK / NACK feedback mechanism in the protocol, increase the number and interval of retransmissions, and implement a fast reconnection mechanism.

[0086] When device performance degrades, strengthen the device's cooling system.

[0087] Frequent disconnection of the terminal will cause the loss of three-remote information, failure of remote control and remote reading and sending of set parameters, seriously affecting the practical application of distribution automation.
