To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart illustrating a method for monitoring a device fault based on a Modbus protocol according to an embodiment of the present application. The method can be applied to a fault monitoring device. As shown in FIG. 1, the Modbus protocol-based device fault monitoring method includes, but is not limited to, the following steps.
And S101, acquiring the state information of the communication equipment to be detected and the real-time working parameters of the communication equipment to be detected according to a Modbus protocol.
The field bus technology (Modbus) protocol is a serial communication protocol, and is used for realizing interaction of communication information between different electronic devices.
For example, through the Modbus protocol, the controllers (e.g., fault monitoring devices) can communicate with each other and with other devices (e.g., communication devices to be detected) via a network (e.g., ethernet), so that control devices produced by different manufacturers can form a communication network to monitor the communication devices to be detected in real time.
Step S102, analyzing the real-time working parameters of the communication equipment to be detected, and determining the change information corresponding to the real-time working parameters.
The real-time working parameters of the communication equipment to be detected can be subjected to curve analysis or abnormal data fluctuation analysis, the change information corresponding to the real-time working parameters can be clearly and definitely observed, and the rapid positioning of abnormal conditions is promoted.
And step S103, determining whether the communication equipment to be detected fails according to the change information corresponding to the real-time working parameters and the state information of the communication equipment to be detected.
The change information corresponding to the real-time working parameters and the state information of the communication equipment to be detected are combined, so that the change condition of the real-time working parameters when the communication equipment to be detected is in different states can be determined, whether the communication equipment to be detected breaks down or not is determined, some slightly changed problems of the communication equipment to be detected are exposed, and the detection accuracy of the communication equipment to be detected is improved.
In this embodiment, the real-time acquisition of the operating data of the communication device to be detected is realized by acquiring the state information of the communication device to be detected and the real-time working parameters of the communication device to be detected according to the Modbus protocol, so as to early warn possible problems of the device in advance; analyzing the real-time working parameters of the communication equipment to be detected, determining the change information corresponding to the real-time working parameters, and highlighting the problem that the change is slight but not easy to be perceived in daily maintenance; according to the change information corresponding to the real-time working parameters and the state information of the communication equipment to be detected, whether the communication equipment to be detected breaks down or not can be quickly and accurately determined, the working intensity of the machine room inspection personnel is reduced, the monitoring strength of the communication equipment to be detected is improved, and normal operation of the equipment in the communication machine room along the railway can be guaranteed.
In some implementations, the communication device to be detected includes: the switching power supply module and/or the plurality of communication boards.
For example, the communication equipment to be detected comprises a switch power supply module and a plurality of communication boards, namely the plurality of communication boards need the switch power supply module to provide corresponding power for the communication boards, so that each communication board can normally work, and the communication equipment to be detected can provide multi-dimensional and all-directional service for the terminal.
Fig. 2 is a schematic flowchart illustrating a method for monitoring a device fault based on a Modbus protocol according to another embodiment of the present application. The method can be applied to a fault monitoring device. The difference between this embodiment and the previous embodiment is: the communication equipment to be detected comprises a switch power supply module, and the state information of the communication equipment to be detected comprises the power supply state information of the switch power supply module. By detecting the power state information of the switch power module, whether the communication equipment to be detected works normally or not can be determined, so that the detection accuracy of the communication equipment to be detected is improved.
As shown in FIG. 2, the Modbus protocol-based device fault monitoring method includes, but is not limited to, the following steps.
Step S201, according to the Modbus protocol, a first transmission format corresponding to the power state information of the switching power supply module is determined.
Wherein, the power state information of the switching power supply module comprises: an on state or an off state. The first transmission format may include: a transmission format determined based on American Standard Code for Information Interchange (ASCII) or a transmission format based on Remote Terminal Unit (RTU).
For example, the transmission format determined based on ASCII may include: a destination address (a network address of the fault monitoring device), a source address (a network address of the switching power supply module), power state information of the switching power supply module, Longitudinal Redundancy Check (LRC) information, and the like.
As another example, an RTU based transmission format may include: a target address (a network address of the fault monitoring device), a source address (a network address of the switching power supply module), power state information of the switching power supply module, Cyclic Redundancy Check (CRC) information, and the like.
The power supply state information of the switching power supply module is transmitted through different transmission formats so as to meet the configuration requirement of the fault monitoring device and accelerate the transmission efficiency of the power supply state information.
It should be noted that, when the communication based on the Modbus protocol is performed between the fault monitoring device and the communication device to be detected, the transmission mode and the serial port parameter of the two devices need to be set identically, for example, the serial port communication parameters (such as baud rate, verification mode, etc.) of the two devices can be configured as the same parameters, so that the two devices can perform normal communication, and the power state information of the switching power supply module in the communication device to be detected can be obtained in time.
Step S202, acquiring the power state information transmitted in the first transmission format through a preset interface between the communication equipment to be detected and the power state information.
The preset interface is a communication interface preset between the fault monitoring device and the communication equipment to be detected. For example, the preset interface may include a serial communication interface (e.g., an RS485 interface or an RS232 interface, etc.).
Based on a specific preset interface, the power state information transmitted in the first transmission format is acquired, the leakage proportion of the power state information can be reduced, and the safety of data transmission is improved.
Step S203, acquiring real-time working parameters of the communication equipment to be detected.
The real-time working parameters are parameters reported by the communication equipment to be detected under the condition that the communication equipment to be detected continuously operates for a first preset time.
For example, the first preset time duration is 2 hours, and the real-time working condition of the communication equipment to be detected can be determined by acquiring the real-time working parameters of the communication equipment to be detected in the process of continuously operating for 2 hours, so as to determine whether the communication equipment to be detected is in a normal working state.
Step S204, analyzing the real-time working parameters of the communication equipment to be detected, and determining the change information corresponding to the real-time working parameters.
It should be noted that step S204 in this embodiment is the same as step S102 in the previous embodiment, and is not repeated herein.
And step S205, determining whether the communication equipment to be detected fails according to the change information corresponding to the real-time working parameters and the power state information of the switching power supply module.
For example, if the switching power supply module is in a power-on state but the real-time voltage suddenly drops or rises, it is determined that the communication device to be detected fails; otherwise, determining that the communication equipment to be detected has no fault.
In this embodiment, through with wait to detect the interface of predetermineeing between the communication equipment, make the fault monitoring device can treat to detect the switching power supply module of communication equipment and carry out incessant control continuously (for example, the fault monitoring device treats to detect the switching power supply module of communication equipment and carries out incessant continuous control for 24 hours) based on the Modbus agreement, make the relevant data of waiting to detect the communication equipment that acquire more accurate, the real-time is better, make things convenient for follow-up trouble that the communication equipment that treats probably appears to in time judge, thereby make the early warning, the normal work of communication equipment that the guarantee is waited to detect.
The embodiment of the present application provides another possible implementation manner, where the communication device to be detected includes: a plurality of communication boards; the state information of the communication equipment to be detected comprises the installation state of the communication board card; in step S101, acquiring status information of the communication device to be detected according to a Modbus protocol, including: determining a second transmission format corresponding to the installation states of the plurality of communication board cards according to a Modbus protocol; and acquiring the installation states of the plurality of communication board cards transmitted in the second transmission format through a preset interface between the communication board cards and the communication equipment to be detected.
The second transmission format is a data transmission format which is matched with a Modbus protocol and is only used for transmitting the installation state of the communication board card.
For example, the second transmission format may include the following information: the target address (the network address of the fault monitoring device), the source address (the network address of the communication equipment to be detected), the installation state of the first communication board, the installation state of the second communication board, … …, the installation state of the nth communication board, the LRC information and the like. And N represents the number of the communication board cards installed in the communication equipment to be detected, and is an integer greater than or equal to 1.
Through with wait to treat and wait to predetermine the interface between the communication equipment, acquire the installation state with a plurality of communication integrated circuit boards of second transmission format transmission, can clearly and definitely wait to treat that how many communication integrated circuit boards have specifically been installed in the communication equipment to and the state information of each communication integrated circuit board, refine the detection precision of treating the communication equipment that detects, promote the detection accuracy of treating the communication integrated circuit board in the communication equipment that detects.
In some specific implementations, the determining, in step S103, whether the communication device to be detected fails according to the change information corresponding to the real-time operating parameter and the status information of the communication device to be detected includes: and determining whether the communication equipment to be detected fails or not according to the change information corresponding to the real-time working parameters and the installation states of the plurality of communication board cards.
The real-time working parameters are obtained under the condition that at least one communication board card is installed in the communication equipment to be detected.
For example, when a communication board card is installed in the communication device to be detected and corresponds to the first voltage, but the real-time voltage (or real-time current) corresponding to the communication device to be detected suddenly drops or rises (for example, the real-time voltage is suddenly changed to twice the first voltage, etc.) at a certain time, it can be determined that the communication board card in the communication device to be detected has a fault.
It should be noted that, if the communication board is in the installation state, it is indicated that the communication board is available, and the communication board needs to be powered by the switching power supply module; if the communication board card is in the uninstalled state, it is characterized that no available communication board card is installed on the communication card slot in the communication equipment to be detected, that is, the communication card slot in the communication equipment to be detected, on which no communication board card is installed, does not need a switching power supply module to provide power for the communication card slot.
The embodiment of the present application provides another possible implementation manner, where the real-time working parameters of the communication device to be detected include: real-time voltage information and/or real-time current information. Analyzing the real-time working parameters of the communication device to be detected in step S102 or step S204, and determining the change information corresponding to the real-time working parameters, including: performing curve analysis on the real-time voltage information, and determining the voltage peak value change information of the communication equipment to be detected within a second preset time; and/or performing curve analysis on the real-time current information to determine current peak value change information of the communication equipment to be detected within a third preset time period.
Wherein, the curve analysis may be to digitally convert the real-time voltage (or real-time current) to determine the voltage values (or current values) at different times, so as to determine the voltage value curve (or current value curve) according to the voltage values (or current values) at various times; through observation of the voltage value curve (or the current value curve), a voltage peak value (or a current peak value) or a voltage valley value (or a current valley value) within a second preset time period (for example, 2 hours, 5 hours, or the like) can be obtained.
The real-time working condition of the communication equipment to be detected can be quickly and accurately determined by linearly representing the change condition of the real-time voltage information (or the real-time current information), and the slight change condition of the communication equipment to be detected in working is detected, so that some problems which are not easy to be found manually are determined, and the accuracy of fault detection is improved.
In some implementations, a switching power supply module includes: an Uninterruptible Power Supply (UPS) or battery module; the status information of the communication device to be detected further includes: the continuous service time of the UPS, or the service time information of the storage battery module.
Among them, Storage batteries (Storage batteries) are a device that directly converts chemical energy into electrical energy, and are batteries designed to be rechargeable, and are recharged by reversible chemical reactions (e.g., lead-acid batteries, etc.). The working principle of the storage battery is as follows: during charging, the internal active substance is regenerated by using external electric energy, and the electric energy is stored as chemical energy; when discharging is needed, the chemical energy is converted into electric energy again for output (for example, a mobile phone battery and the like which are commonly used in life).
The UPS can provide continuous, stable and uninterrupted power supply for the communication equipment to be detected. In principle, the UPS is a power electronic device that integrates digital and analog circuits, an automatic control inverter, and a maintenance-free energy storage device. Functionally, the UPS can effectively purify the commercial power when the commercial power is abnormal; and when the commercial power is suddenly interrupted, the power can be supplied to the communication equipment to be detected for a certain time, so that the communication equipment to be detected can have sufficient time to respond. For purposes, the UPS may also be applied to various links from information collection, transmission, processing, and storage to an application of the communication device to be detected.
Realize switching power supply module through the mode of difference, can make and wait to detect communication equipment and can continue work to guarantee to wait to detect communication equipment's normal operating, promote user terminal's use and experience.
In some specific implementations, after determining whether the communication device to be detected fails according to the change information corresponding to the real-time operating parameter and the status information of the communication device to be detected in step S103, the method further includes: determining the failure frequency of the communication equipment to be detected within a fourth preset time under the condition that the communication equipment to be detected fails; determining the service life of the UPS according to the failure times and the continuous service life of the UPS; or determining the service life of the storage battery module according to the failure times and the service life information of the storage battery module.
Wherein, the fourth preset time duration may be a time length of a statistical period of the number of failures. For example, the fourth preset time period may be 1 year or 2 years, etc. And determining whether the switching power supply module reaches the maximum service life or not by acquiring the failure times of the communication equipment to be detected in the fourth preset time and the continuous service time of different switching power supply modules. For example, the preset service life of the UPS is 6 years, and the number of times of failure that the UPS fails in the 5 th year when the UPS is used is 5 times, which is greater than the preset number of times of failure (e.g., 2 times), it is indicated that the UPS needs to be replaced to prevent the interruption of the operation of the communication device to be detected due to the UPS being unusable.
The service life of the UPS or the storage battery is judged in advance so as to be replaced in advance, the work interruption of the communication equipment to be detected due to the fact that the UPS or the storage battery cannot be used is prevented, the continuous working time of the communication equipment to be detected is prolonged, and the working efficiency of the communication equipment to be detected is improved.

The communication device 410 to be detected may include a switching power supply module and a plurality of communication boards (not shown in the figure), the switching power supply module is configured to provide power for the plurality of communication boards, and the plurality of communication boards are configured to provide a multidimensional communication service to the terminal.
It should be noted that, if the communication board is in the installation state, it is indicated that the communication board is available, and the communication board needs to be powered by the switching power supply module; if the communication board is in the uninstalled state, it is characterized that no available communication board is installed on the communication card slot in the communication device 410 to be detected, that is, the communication card slot in the communication device 410 to be detected, on which no communication board is installed, does not need to be powered by the switching power supply module.
The fault monitoring device 420 is configured to obtain, according to a Modbus protocol, status information of the communication device 410 to be detected and real-time operating parameters of the communication device 410 to be detected; analyzing the real-time working parameters of the communication equipment 410 to be detected, and determining the change information corresponding to the real-time working parameters; and determining whether the communication equipment 410 to be detected fails according to the change information corresponding to the real-time working parameters and the state information of the communication equipment 410 to be detected.
In some specific implementations, the fault monitoring device 420 may also report the obtained status information of the communication device 410 to be detected and the real-time operating parameters of the communication device 410 to be detected to the server, so that the server analyzes a large amount of data corresponding to the communication device 410 to be detected, so as to determine whether the communication device 410 to be detected has a fault.
In some implementations, the communication device 410 to be detected can include: any one of an air conditioner, a lighting device, and a base station in a communication room. Through a serial communication (Modbus) protocol, real-time working parameters, state information and the like of the communication equipment 410 to be detected of different types are acquired in real time, remote monitoring (for example, continuous 24H monitoring) of each equipment in a communication machine room can be realized, the workload of operation and maintenance personnel is reduced, and the machine room on duty is gradually developed towards an unmanned direction.
Fig. 5 is a schematic flowchart illustrating an operating method of a device fault monitoring system based on a Modbus protocol according to an embodiment of the present application. As shown in FIG. 5, the Modbus protocol-based device fault monitoring method includes, but is not limited to, the following steps.
In step S501, the fault monitoring device 420 interacts with the communication device 410 to be detected through a preset interface, and obtains status information of the communication device 410 to be detected and real-time operating parameters of the communication device 410 to be detected according to a Modbus protocol.
The preset interface may include an RS485 interface or an RS232 interface. The preset interface is an interface for performing information interaction, which is preset by the communication device 410 to be detected and the fault monitoring device 420.
The relevant information of the communication equipment 410 to be detected is obtained in real time through the Modbus protocol, and data monitoring of the communication equipment 410 to be detected can be achieved.
In some implementations, the switching power supply module of the communication device 410 under test reports its power status information to the fault monitoring device 420 in a first transmission format, wherein the first transmission format is a data transmission format determined based on the Modbus protocol.
For example, the first transmission format may include an ASCII-based determined transmission format, or an RTU-based transmission format.
In which each 8-Bit byte is transmitted as two ASCII characters in a transmission format determined based on ASCII, the main advantage of this transmission format is that the time interval for character transmission is significantly shortened (e.g., 1 second) without generating errors. In an RTU based transmission format, each 8-Bit byte includes two 4-Bit hexadecimal characters. In the case where the baud rate is determined to be the same, data transmission using the RTU-based transmission format enables data transmission in a larger amount than data transmission using the ASCII-based transmission format.
It should be noted that, the device that uses the Modbus protocol for data transmission needs to select the same transmission mode and serial communication parameters (for example, baud rate, verification mode, etc.). For example, it is only necessary to set the transmission mode and the serial port communication parameter corresponding to the communication device 410 to be detected and the fault monitoring device 420 to be the same, that is, the two devices perform data transmission based on the Modbus protocol.
The real-time operating parameters of the communication device 410 to be detected may include: real-time voltage information and/or real-time current information. The status information of the communication device 410 to be detected includes the installation status of the communication board card and/or the power status information of the switching power supply module.
The communication device 410 to be detected is continuously monitored by the fault monitoring device 420 (for example, the communication device 410 to be detected is continuously monitored for 24 hours by the fault monitoring device 420), so that the acquired related data of the communication device 410 to be detected is more accurate, the real-time performance is better, and the subsequent fault which may occur to the communication device 410 to be detected can be conveniently and timely judged.
In step S502, the fault monitoring device 420 performs curve analysis on the real-time voltage information of the communication device 410 to be detected to determine the voltage peak change information of the communication device 410 to be detected within a second preset time period, and/or performs curve analysis on the real-time current information of the communication device 410 to be detected to determine the current peak change information of the communication device 410 to be detected within a third preset time period.
In step S503, the fault monitoring device 420 performs comprehensive analysis on the voltage peak change information of the communication device 410 to be detected within the second preset time period and/or the current peak change information of the communication device 410 to be detected within the third preset time period, respectively, with the installation state of the communication board and the power state information of the switching power supply module, so as to obtain an analysis result.
For example, the voltage peak variation information or the current peak variation information may be subjected to curve analysis to determine a variation of a peak value (e.g., a peak value or a valley value, etc.) within a second preset time period; the method can also analyze the fluctuation of abnormal data of the installation state of the communication board card and the power state information of the switching power supply module to generate a life cycle running report, thereby comprehensively considering different analysis change conditions and determining an analysis result so as to enable the analysis result to be more accurate.
In step S504, the failure monitoring device 420 determines whether the communication device 410 to be detected fails according to the analysis result.
The voltage peak change information of the communication device 410 to be detected in the second preset time period and/or the current peak change information of the communication device 410 to be detected in the third preset time period may be analyzed in combination with the power state information of the switching power supply module, and based on the analysis result, whether the communication device 410 to be detected fails or not may be determined.
For example, if the switching power supply module is in the power-on state, but the real-time voltage suddenly drops or rises (or the real-time current suddenly rises or falls), it is determined that the communication device 410 to be detected has a fault, and the communication device 410 to be detected needs to be maintained in time to ensure the normal operation of the communication device 410 to be detected.
For example, the voltage peak change information of the communication device 410 to be detected within the second preset time period and/or the current peak change information of the communication device 410 to be detected within the third preset time period may be combined with the installation state of the communication board for analysis to determine whether the communication device 410 to be detected has a fault.
It should be noted that, in the case that it is determined that the communication device 410 to be detected has a fault, step S505 is executed; otherwise, in case that it is determined that the communication device 410 to be detected has not failed, the flow is ended.
In some specific implementations, in the case that it is determined that the communication device 410 to be detected has not failed, the step S501 may be returned again to continue to detect the real-time data of the communication device 410 to be detected.
Step S505, when it is determined that the communication device 410 to be detected has a fault, generating a prompt message, and displaying the prompt message to an operation and maintenance worker, so that the operation and maintenance worker can maintain the communication device 410 to be detected, and ensure the normal operation of the communication device 410 to be detected.
For example, the fault monitoring device 420 may obtain an implementation manner of the switching power supply module (for example, a UPS or a storage battery is used to obtain a power supply), and determine the number of times that the communication device to be detected fails within a fourth preset time period when the communication device to be detected fails; determining the service life of the UPS according to the failure times and the continuous service life of the UPS; or determining the service life of the storage battery module according to the failure times and the service life information of the storage battery module.
By determining the service life of the switching power supply module, whether the switching power supply module of the communication device 410 to be detected needs to be maintained or replaced can be determined, and early warning can be given to possible faults of the communication device 410 to be detected; therefore, operation and maintenance personnel are prompted to maintain or replace the switching power supply module of the communication device 410 to be detected in time, and normal work of the communication device 410 to be detected is guaranteed.
In this embodiment, the fault monitoring device 420 is used to continuously monitor the communication device 410 to be detected, and according to the Modbus protocol, obtain the status information of the communication device to be detected and the real-time operating parameters of the communication device to be detected, so as to achieve real-time obtaining of the operating data of the communication device to be detected, and provide for early warning of possible problems of the device; the fault monitoring device 420 performs curve analysis on the real-time voltage information of the communication device 410 to be detected to determine the voltage peak value change information of the communication device 410 to be detected within a second preset time period, and/or performs curve analysis on the real-time current information of the communication device 410 to be detected to determine the current peak value change information of the communication device 410 to be detected within a third preset time period. And the voltage peak value change information of the communication equipment 410 to be detected in the second preset time period and/or the current peak value change information of the communication equipment 410 to be detected in the third preset time period are/is comprehensively analyzed with the installation state of the communication board card and the power state information of the switching power supply module respectively,
obtaining an analysis result, highlighting the problem of slight change but not easy to be perceived in daily maintenance; according to the analysis result, whether the communication equipment to be detected breaks down can be judged quickly and accurately, the working strength of the machine room patrol personnel is reduced, and the monitoring strength of the communication equipment to be detected is improved; and generating prompt information under the condition that the communication equipment 410 to be detected fails, and displaying the prompt information to operation and maintenance personnel, so that the operation and maintenance personnel can maintain the communication equipment 410 to be detected, and the normal operation of the communication equipment 410 to be detected in the communication machine room along the railway can be guaranteed.
