[0004] At present, the controller generally transmits the vibration value of the transformer to the computer through a single WIFI channel. If the WIFI channel is interrupted, the computer will not be able to receive the vibration value normally. This method has the disadvantages of low accuracy, poor confidence, and time-consuming and labor-intensive vibration value confirmation. Summary of the invention

[0005] In order to solve the defects in the prior art, the present invention proposes a system and method for transmitting the vibration value of the transformer, which effectively avoids the defects in the prior art that the interruption of the WIFI channel prevents the computer from collecting the vibration value normally, the accuracy is not high, the confidence is not good, and it takes time and effort to handle the vibration value confirmation.

[0006] The present invention uses the following technical solutions.

[0007] A method for transmitting a vibration value of a transformer, comprising: The vibration sensor collects the vibration value of the transformer and transmits it to the controller, and the controller transmits the vibration value of the transformer to the computer for display; The method for the controller to transmit the vibration value of the transformer to the computer includes: Step 1: The controller obtains the vibration value to be transmitted and synchronously sends the vibration value to channel 1 and channel 2; Step 2: Copy the vibration values ​​transmitted by channel 1 and channel 2 to the value storage space; Step 3: Repeatedly at a defined time interval, according to the signal quantity of the vibration value transmitted by channel 1 and channel 2 or the signal receiving time point, identify the channel and time point where the transmission interruption occurs; Step 4: According to the channel and time point where the transmission interruption occurs, the target value is obtained through the controller or the value storage space, and then transmitted to the destination; Step 5: Receive and store the vibration values ​​transmitted by channel 1 and channel 2, waiting for transmission after external request.

[0008] Further, in step 1, the vibration value includes a plurality of vibration signals, and during the transmission period, the vibration signals are arranged in the order of their collection time points to form a signal queue; Each signal contains the signal value, the signal collection time point and the signal identification code.

[0012] Further, in step 3, the signal receiving time point is the time point when the signal arrives at the computer.

[0013] Further, in step 4, the target value is the vibration value lost when the channel generates an interruption, and the destination is the channel where the interruption occurs. The target value is obtained through a controller or a value storage space. The target value corresponding to the time point when the interruption occurs can be identified based on the time point of signal collection, or the value of the signal with the corresponding target value can be grasped at the time point based on another channel that has not generated a transmission interruption, and the target value is obtained through a controller or a value storage space.

[0014] Furthermore, in step 4, after the vibration value is reached and retransmitted, the vibration values ​​transmitted by the two channels arrive at the computer. At this time, the transmitted vibration values ​​are stored in a pre-defined information table in the computer, and the corresponding vibration value requirements are transmitted according to different external requests.

[0015] Furthermore, in step 3, according to the signal amount or signal receiving time point of the vibration value transmitted by channel 1 and channel 2, the method of identifying the channel and time point where the transmission interruption occurs includes: Calculating the difference between the signal quantities of the vibration values ​​transmitted by channel 1 and channel 2; If the difference between the semaphore values ​​exceeds the semaphore threshold, the channel with the smaller semaphore value is identified and transmission is interrupted.

[0016] Furthermore, in step 3, the method of identifying the channel and time point where the transmission interruption occurs according to the signal amount or signal receiving time point of the vibration value transmitted by channel 1 and channel 2 may also be: Calculating the difference in the time point of receiving the same signal within the vibration value transmitted by channel 1 and channel 2; If the difference in receiving time points exceeds the critical time point, it is determined that the channel where the signal with the late receiving time point is located has a transmission interruption.

[0017] Furthermore, in step 3, the method of identifying the channel and time point where the transmission interruption occurs according to the signal amount or signal receiving time point of the vibration value transmitted by channel 1 and channel 2 may also be: The signal amounts of the vibration values ​​transmitted by channel 1 and channel 2 are respectively totaled; the channel whose signal amount does not exceed the defined minimum amount is identified as the channel where the transmission interruption occurs.

[0019] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include: By using a two-channel vibration value transmission method, the confidence and reliability of the entire vibration value transmission channel are enhanced. Not only does it eliminate the adverse effects of the current single channel interruption on the credibility of vibration value transmission, but it also avoids the defects of requiring time-consuming and labor-intensive adjustment and guarantee, as well as the additional defects of vibration value confirmation. When the channel configuration is adjusted and changed synchronously, the change can be achieved without being noticed, thereby better reducing the adverse effects of vibration value transmission interruption. The vibration value to be transmitted is obtained through the controller, and the vibration value is synchronously sent to channel one and channel two; the vibration value transmitted by channel one and channel two is copied to the numerical storage space; repeatedly at a defined time interval, the channel and time point where the transmission interruption occurs are identified according to the signal amount or signal collection time point of the vibration value transmitted by channel one and channel two; according to the channel and time point where the transmission interruption occurs, the controller or The target value is obtained from the value storage space and then transmitted to the destination; the vibration values ​​transmitted by channel one and channel two are collected and stored, and are transmitted after being requested by the outside world, thereby realizing the active monitoring of vibration value transmission interruptions and vibration value retransmission.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 is a partial flow chart of the method for transmitting vibration values ​​of a transformer according to the present invention; Figure 2 It is a partial structural diagram of the transmission system for the vibration value of the transformer described in the present invention. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely expressed in combination with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only some embodiments of the present invention, not all embodiments. According to the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the protection scope of the present invention.

[0022] like Figure 1 As shown, a method for transmitting vibration values ​​of a transformer according to the present invention comprises: The vibration sensor collects the vibration value of the transformer and transmits it to the controller, and the controller transmits the vibration value of the transformer to the computer for display, thereby achieving the purpose of monitoring the vibration value of the transformer; The method of the controller (which may be a single chip microcomputer or a PLC) transmitting the vibration value of the transformer to the computer includes: The present application constructs a vibration value transmission interruption monitoring mode based on two channels, and by comparing the transmission differences of the same vibration value on the two channels, grasps the location where the transmission interruption occurs, thereby performing active retransmission of the lost vibration value. The channels of the present application are all WIFI channels.

[0023] Under the current single channel conditions, WLAN interruption, controller failure, etc. will all cause channel interruption. If the WIFI channel is interrupted, the computer will be unable to collect vibration values ​​normally, which has the advantages of low accuracy and poor confidence. It also takes time and effort to process vibration value confirmation. In addition, in the face of a single channel, more software and hardware for configuration adjustment must be added, and the implementation cost will increase accordingly. Channel improvement and replacement will also temporarily suspend the current vibration value transmission, which has the adverse consequence of interrupting the vibration value connection of the computer, and cannot achieve improvement without being noticed.

[0024] The method of the present application enables the interruption monitoring of vibration value transmission and the retransmission of vibration values ​​to be executed actively, thereby reducing the cost of time-consuming and labor-intensive human control, thereby improving the confidence level of vibration value transmission.

[0025] The system for transmitting vibration values ​​includes a controller, a computer and a transmission channel.

[0026] The transmission channel is responsible for transmitting the vibration values ​​between the controller and the computer. To ensure the completeness and efficiency of the transmitted vibration values, the transmission channel of this application is two channels, and a pair of channels synchronously transmit the same vibration value.

[0027] The two channels include channel 1 and channel 2. The controller (which may be a single chip microcomputer or a PLC) transmits the vibration value of the transformer to the computer, specifically including: Step 1: The controller obtains the vibration value to be transmitted and synchronously sends the vibration value to channel 1 and channel 2; In a preferred but non-limiting embodiment of the present invention, in step 1, the vibration value includes a plurality of vibration signals, and during the transmission period, the vibration signals are arranged in the order of their collection time points to form a signal queue; Each signal contains the value of the signal, the time when the signal was collected, and the signal identification code. The same signal has the same value of the signal, the time when the signal was collected, and the signal identification code. The identification code is a special symbol defined in advance to distinguish the signal from other signals.

[0028] In a preferred but non-limiting embodiment of the present invention, in step 1, the two channels include channel 1 and channel 2, and the pair of channels are used to transmit the same vibration value concurrently or synchronously. If the pair of channels does not generate a transmission interruption during the transmission, the same signal transmitted in the pair of channels should arrive synchronously; if any one of the pair of channels generates a transmission interruption, the same signal transmitted by the pair of channels cannot arrive synchronously.

[0029] Step 2: Copy the vibration values ​​transmitted by channel 1 and channel 2 to the value storage space; In a preferred but non-limiting embodiment of the present invention, in step 2, a value storage space is provided in the main memory of the controller to store the entire vibration value to be transmitted, so that the vibration value can obtain the target value when it is transmitted again. The transmitted vibration value obtained by copying can be the same as the vibration value or different.

[0030] Step 3: Repeatedly at a defined time interval, according to the signal quantity of the vibration value transmitted by channel 1 and channel 2 or the signal receiving time point, identify the channel and time point where the transmission interruption occurs; In a preferred but non-limiting embodiment of the present invention, in step 3, the defined time interval is a defined duration, such as 2 minutes, 3 minutes or 25 seconds. The length of the duration can be pre-defined according to the interruption monitoring accuracy requirements. The lower the duration, the better the interruption monitoring accuracy. The monitoring of transmission interruptions is repeatedly performed, and the time gap between the previously defined time interval and the next defined time interval can also be pre-defined. The lower the time gap, the better the interruption monitoring accuracy.

[0031] If there is no transmission interruption in channel 1 or channel 2, the vibration values ​​transmitted by the two channels should be the same or have a small difference. Therefore, the signals transmitted by the two channels in the same time period should be the same or have a small difference. The same signal arriving at the same channel at the same time point during the transmission of the two channels should be the same or have a small difference. Therefore, based on the difference in the vibration values ​​transmitted by channel 1 and channel 2, it can be compared and identified that the channel with a large difference has a transmission interruption at a defined time interval.

[0032] Just as the channel and time point where transmission interruption occurs can be identified based on the signal volume of the vibration values ​​transmitted by channel 1 and channel 2, the signal volume is the number of signals contained in the vibration values ​​transmitted in the above time length. In the defined time interval, if channel 1 and channel 2 do not cause transmission interruption, the signal volume transmitted by channel 1 or channel 2 should be the same or have a very small difference.

[0033] Just as the channel and time point where a transmission interruption occurs can be identified based on the signal collection time point of the vibration values ​​transmitted by channel one and channel two, in a preferred but non-limiting embodiment of the present invention, in step 3, the signal collection time point is the time point when the signal arrives at the computer. If there is no transmission interruption between channel one and channel two, the signal collection time points of the same signal transmitted by channel one and channel two should be the same or have very little difference. Therefore, the channel and time point with transmission interruption can be compared based on the difference in the vibration values ​​transmitted by channel one or channel two at a defined time interval.

[0034] In addition, the channel and time point where the transmission interruption occurs can be identified synchronously based on the signal volume of the vibration value transmitted by channel 1 and channel 2 and the time point of signal collection, so as to improve the monitoring accuracy.

[0035] Step 4: According to the channel and time point where the transmission interruption occurs, the target value is obtained through the controller or the value storage space, and then transmitted to the destination; In a preferred but non-limiting embodiment of the present invention, in step 4, the destination value is the vibration value lost when the channel is interrupted, and the destination is the channel where the interruption occurs. The destination value is obtained through a controller or a value storage space. The destination value corresponding to the time point when the interruption occurs can be identified based on the time point of signal collection, or the value of the signal with the corresponding destination value can be grasped at the time point based on another channel that has not generated a transmission interruption, and the destination value is obtained through a controller or a value storage space.

[0036] After identifying the channel and time point where the transmission interruption occurs, the channel and time point where the transmission interruption occurs can be synchronized and instantly sent to the pre-defined file in the controller, and then displayed on the LCD screen connected to the controller. During manual control, corresponding adjustments can be performed based on the channel and time point where the transmission interruption occurs.

[0037] Step 5: Receive and store the vibration values ​​transmitted by channel 1 and channel 2, waiting for transmission after external request.

[0038] In a preferred but non-limiting embodiment of the present invention, in step 4, after the vibration value is reached and retransmitted, the vibration values ​​transmitted by the two channels arrive at the computer, and the transmitted vibration values ​​are stored in a predefined information table in the computer, and the corresponding vibration value requirements are transmitted according to different external requests. The external request is a command from another intelligent device (industrial computer, etc.) connected to the computer for requesting to share the vibration value.

[0039] Based on this, the vibration value to be transmitted is obtained through the controller, and the vibration value is synchronously sent to channel one and channel two; the vibration value transmitted by channel one and channel two is copied to the numerical storage space; repeatedly at a defined time interval, according to the signal amount or signal collection time point of the vibration value transmitted by channel one and channel two, the channel and time point where the transmission interruption occurs are identified; according to the channel and time point where the transmission interruption occurs, the target value is obtained through the controller or the numerical storage space, and then transmitted to the destination; the vibration value transmitted by channel one and channel two is collected and stored, and is transmitted after being requested by the outside world, in this way, by constructing two channels. The vibration value transmission rule improves the transmission accuracy. When a transmission interruption occurs on one channel, the vibration value can still be transmitted to the right place through another channel, which greatly improves the transmission confidence of the vibration value. The two channels are used to construct a transmission interruption monitoring mode, and the same vibration value is transmitted to the two channels synchronously. By comparing the transmission differences of the same vibration value on the two channels, the channel where the transmission interruption occurs is monitored, and the lost vibration value is actively retransmitted, thereby achieving intelligent maintenance of vibration value transmission interruption, which can further improve the transmission confidence and adaptability of vibration values, reduce human control costs, and improve user experience.

[0040] The channel and time point where the transmission interruption occurs can be identified based on the signal amount of the vibration value transmitted by channel one and channel two or the signal collection time point. The channel and time point where the transmission interruption occurs can be identified based on the difference in signal amount, the difference in collection time point or the signal amount at a defined time interval.

[0041] In a preferred but non-limiting embodiment of the present invention, in step 3, the method of identifying the channel and time point where the transmission interruption occurs according to the signal amount or signal receiving time point of the vibration value transmitted by channel 1 and channel 2 includes: Calculate the difference between the signal amounts of the vibration values ​​transmitted by channel 1 and channel 2 (the difference is the absolute value of the amount obtained by subtracting the signal amount of the vibration value transmitted by channel 2 from the signal amount of the vibration value transmitted by channel 1); If the difference in the signal volume is higher than the signal volume threshold, it is determined that the channel with the smaller signal volume has caused a transmission interruption. Here, the signal volume threshold can be pre-defined according to specific requirements. The signal volume threshold determines the accuracy of interruption monitoring. When a pair of channels perform synchronous transmission of the same vibration value, in the same length of time, the signal volume through the two channels should be the same or have a very small difference. If the difference is not small, it means that the channel with a lower transmission rate has caused a transmission interruption, and the channel has lost some signals. The signal volume is the number of signals.

[0042] In a preferred but non-limiting embodiment of the present invention, in step 3, the method of identifying the channel and time point where the transmission interruption occurs according to the signal amount or signal collection time point of the vibration value transmitted by channel 1 and channel 2 may also be: Calculate the difference between the receiving time points of the same signal in the vibration value transmitted by channel 1 and channel 2 (the difference is the absolute value of the amount obtained by subtracting the receiving time point of the same signal in the vibration value transmitted by channel 1 from the receiving time point of the same signal in the vibration value transmitted by channel 2); If the difference in the receiving time point is higher than the critical time point, it is determined that the channel where the signal with the late receiving time point is located has a transmission interruption. Here, the critical time point can be pre-defined according to specific requirements. The critical time point determines the accuracy of interruption monitoring. When a pair of channels perform synchronous transmission of the same vibration value, the receiving time points of the same signal arriving at the same monitoring point in a pair of channels should be the same or have a very low difference. If the difference is not small, it means that the channel with a later receiving time point has a transmission interruption. Just like, at a time interval of 2 minutes, facing the same signal three, it has been successfully transmitted by channel one, but not received in channel two, which means that channel two has a transmission interruption. The signal volume through the two channels should be the same or have a very low difference. If the difference is not small, it means that the slower transmission channel has a transmission interruption and some signals have been lost in this channel.

[0043] In a preferred but non-limiting embodiment of the present invention, in step 3, the method of identifying the channel and time point where the transmission interruption occurs according to the signal amount or signal collection time point of the vibration value transmitted by channel 1 and channel 2 may also be: The signal amounts of the vibration values ​​transmitted by channel one and channel two are summed up respectively; the channel whose signal amount does not exceed the defined minimum amount is identified as the channel where the transmission interruption occurs. For the vibration values ​​transmitted synchronously by a pair of channels, if the transmission interruption occurs at a constant time interval, then the signal amount transmitted by each channel should be constant, just as about eighty signals can be transmitted in 1 minute. If the channel only transmits twenty signals in the 1 minute, it is obvious that the vibration value is lost. The defined minimum amount can be defined according to specific requirements, just as the average of the past transmission amounts is used. In this application, the dedicated monitoring of a separate channel can be achieved based on whether the signal amount of each channel exceeds the minimum amount at a fixed time interval, which can provide a pair of channels with synchronous transmission interruption and cannot detect the corresponding situation through comparative monitoring, thereby further improving the accuracy of transmission interruption monitoring.

[0044] The above signal quantity critical quantity, time point critical quantity and the total characteristics of the defined minimum energy combined with the vibration value define parameters that are more accurately in line with the actual interruption conditions, thereby reducing the amount of operations for manually estimating parameter settings.

[0046] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include: By using a two-channel vibration value transmission method, the confidence and reliability of the entire vibration value transmission channel are enhanced. Not only does it eliminate the adverse effects of the current single channel interruption on the credibility of vibration value transmission, but it also avoids the defects of requiring time-consuming and labor-intensive adjustment and guarantee, as well as the additional defects of vibration value confirmation. When the channel configuration is adjusted and changed synchronously, the change can be achieved without being noticed, thereby better reducing the adverse effects of vibration value transmission interruption.
