Example 1

Fig. 1 is a flowchart of a method for correcting timing time according to a first embodiment of the present invention, where the present embodiment is applicable to a device without a timing clock correction function. The method may be performed by a timing time corrected apparatus, which may be implemented in hardware and/or software, which may be configured on a computer device, which may be a notebook, desktop computer, smart tablet, or the like. As shown in fig. 1, the method includes:

s110, determining a second device which establishes communication connection with the first device.

The device is an intelligent electronic device IED (Intelligent Electronic Device) in an electric power automation system, and for example, the device may be a gas insulated switchgear, XLPE cable, generator, transformer, circuit breaker, contactor, and the like. The device comprises a timer for executing the timing task. The first timer in the first device does not have a timing clock correction function and the second timer in the second device does have a timing clock correction function. The timer in the second device can pulse the second timer of the second device to time through the GPS or Beidou external equipment and the like, so that the function of timing clock correction is realized. The number of second devices may be one or more. In this embodiment, the timing time of the second device is accurate, and the timing time of the first device is corrected.

In an actual production process, a large number of first devices and second devices are configured, and the first devices can transmit data to the upper-level devices based on the timer timing. The first device timing the transmission of data to the previous level device includes two scenarios: the first is that the original data collected by the first equipment is uploaded to a data aggregator at regular time; the second is that the original data collected by the first device is transmitted to the second device at regular time, and the second device uploads the received data to the data aggregator. For the first case, the data aggregator may be the second device. For the second case, some second devices may receive data from a plurality of first devices, some first devices have a one-to-one data transfer relationship with the second devices, and some first devices send data to a plurality of other devices, where the other devices include a portion of the second devices and a portion of the first devices, based on which the first device needs to determine the second device to establish a communication connection with the first device.

Specifically, in the process of transmitting data to the second device at regular time, the first device may determine the second device corresponding to the first device based on the data packet uploading path, and based on this, may determine the second device that establishes communication connection with the first device according to the data packet uploading path corresponding to the first device.

S120, receiving a first message sent by the second device, and acquiring first timing position information in a first timer when the first message is received.

The first message is a data message sent to the first device by the second device for the first time, and the first message includes a first sending timestamp. The first sending timestamp is the corresponding time when the second device sends the first message to the first device. The first timing position information is coding information corresponding to the position of a timing pointer of the first timer when the first device receives a first message from the second device.

Specifically, when the timing time of the first device is corrected, the second device sends a first message to the first device. Before the second device sends the first message, the first message is first generated, and the specific content in the first message is not limited. Recording a first sending time stamp at an instant when the first message is sent, and adding the first sending time stamp to the first message. The specific time of the second device sending the first message is not limited, and when the first device receives the first message sent by the second device, the first device determines the coding information corresponding to the position of the timing pointer in the timer numerical code at the moment.

For example, referring to fig. 2, as shown in fig. 2, a second device first sends a first message to a first device, and when the first device receives the first message, a timestamp corresponding to the first device is T1. At time T1, the code information corresponding to the position of the timing pointer of the first timer in the timer value code is "1", so the first timing position information is "1".

S130, receiving a second message sent by the second device based on the second timer, and acquiring second timing position information in the first timer when receiving the second message.

The first message is a data message sent to the first device by the second device for the second time, and the second message includes a second sending timestamp. The first sending timestamp is the corresponding time when the second device sends the second message to the first device. The second timing position information is coding information corresponding to the position of the timing pointer of the first timer when the first device receives the second message from the second device.

Specifically, the second device may, by having a second timer with a timing clock correction function, pass through an accurate preset time, for example, the preset time is 1ms, after sending the first message, and the second device sends the second message including the first sending timestamp to the first device again. When the first device receives a second message sent by the second device, the first device determines coding information corresponding to the position of the timing pointer in the timer numerical code in the moment.

For example, as shown in fig. 2, after the second device sends the first message to the first device, after 1ms, the second device sends the second message to the first device, and when the first device receives the second message, the timestamp corresponding to the first device is T2. At time T2, the code information corresponding to the position of the timing pointer of the first timer in the timer value code is "41", so the second timing position information is "41".

In addition, T1 corresponding to the time when the first device received the first message and T2 corresponding to the time when the first device received the second message are recorded in the process of correcting the timing time of the first device, but T1 and T2 are only used to determine the first timing position information corresponding to the time T1 and the second timing position information corresponding to the time T2. Since the first device does not have a timing clock correction function, the time information of the first device is not standard information and cannot be directly used for correcting the timing time of the first device.

S140, determining a unit position change amount corresponding to a unit time in the first timer based on the first transmission time stamp, the second transmission time stamp, the first timing position information, and the second timing position information.

The unit position change amount is the amount of numerical code change that the timing pointer in the first timer passes through when the unit time passes.

Specifically, according to the first transmission time stamp and the second transmission time stamp, a time interval corresponding to the two times of data messages transmitted by the second device can be determined. From the first timing position information and the second timing position information, an amount of numerical code change traversed by the timing hands in the first timer may be determined. Based on this, the amount of change in unit position corresponding to the unit time in the first timer can be determined from the amount of change in the numerical code that the timing hands have passed over and the time interval.

It should be specifically noted that, in the communication process of the electric power internet of things, the network delay of the first device for receiving the data message sent by the second device is basically fixed, so that the network delay does not affect the time accuracy of the data message received by the first device.

Alternatively, the unit position change amount determined in the above step may be stored in the data table. In practical application, when the timing time of the first device needs to be corrected, the unit position variation corresponding to the unit time in the first timer can be directly called.

In another embodiment, the unit position change amount corresponding to the unit time in the first timer may be determined once every a preset time period, and the unit position change amount in the data table may be updated. For example, the unit position change amount corresponding to the unit time in the first timer is determined every other week.

And S150, determining a target position change amount based on the unit position change amount and the preset time in the first timer, and correcting the current position change amount corresponding to the preset time in the first timer based on the target position change amount.

The preset timing time is an attribute of the first timer, which can be understood as that the first timer triggers a timing task of the first device every preset timing time, so that the first device sends data to the primary device. In practical applications, how often the first device transmits data to the next-level device is predetermined, and thus the preset timing time is a determined amount.

The target position change amount is the amount of numerical code change that the timing pointer in the first timer should walk through in a preset timing time. The current position change amount is the amount of numerical code change actually passed by the timing pointer in the first timer in a preset timing time.

Specifically, on the basis of determining the unit position change amount and the preset time in the first timer, the product of the unit position change amount and the preset time in the first timer is the target position change amount. Further, the current position variable quantity corresponding to the first timer in the preset time is replaced by the target position variable quantity, so that the timing time of the first device is corrected.

In this embodiment, after the first timer in the first device is used for a long time, the current position variation corresponding to the preset time by the first timer cannot accurately represent the preset time, and based on this, the current position variation is replaced by the target position variation, so that the correction of the first device timing time can be realized.

Based on the above embodiment, S110 specifically includes the following steps: and determining candidate devices which are in communication connection with the first device based on the data uploading path of the first device, wherein the device with the time tag function is determined as a second device from the candidate devices.

The data uploading path is used for representing the communication connection relation between the first equipment and the second equipment. The candidate devices are all devices that establish a communication connection with the first device.

The first device is in communication connection with two second devices, and the first device establishes communication connection with two other devices at the same time, wherein the code number corresponding to the first device is a, the two second devices comprise a second device 1 and a second device 2, the code number corresponding to the second device 1 is 001, and the code number corresponding to the second device 2 is 002; the two other devices include the other device 1 and the other device 2, the code number corresponding to the other device 1 is 01, the code number corresponding to the other device 2 is 02, and the data uploading path can be expressed as "A/001-002-01-02". The candidate devices include the second device 1, the second device 2, the other devices 1, and the other devices 2.

In this embodiment, based on the data upload path of the first device, a candidate device that establishes a communication connection with the first device may be determined. The candidate device includes other devices that are not the second device, and the second device may be determined from the candidate devices based further on the code format corresponding to the first device.

Example two

Fig. 3 is a flowchart of a method for timing time correction according to a second embodiment of the present invention, where on the basis of the foregoing embodiments, the "determining a unit position change amount corresponding to a unit time in a first timer based on a first transmission time stamp, a second transmission time stamp, first timing position information, and second timing position information" and the "determining a preset timing time in the first timer based on the unit position change amount, the step of determining the target position change amount and correcting the current position change amount corresponding to the preset time in the first timer based on the target position change amount is further optimized, and the embodiment of the present invention may be combined with each of the alternatives in the one or more embodiments. As shown in fig. 3, the method includes:

s210, determining a second device which establishes communication connection with the first device, wherein a first timer in the first device does not have a timing clock correction function, and a second timer in the second device has the timing clock correction function.

S220, receiving a first message sent by the second equipment, acquiring first timing position information in a first timer when the first message is received, the first message includes a first sending timestamp.

S230, receiving a second message sent by the second device based on the second timer, and acquiring second timing position information in the first timer when receiving the second message, wherein the second message comprises a second sending time stamp.

S240, determining a timing transmission duration corresponding to the second timer based on the first transmission time stamp and the second transmission time stamp.

The timing sending duration is the time interval of sending two times of data messages by the second device.

In this embodiment, the second device sends the second message to the first device again after a period of time has elapsed after sending the first message to the first device, and although this period of time has elapsed is directly available, this period of time is not an exact value. The timing transmission duration corresponding to the second timer determined based on the first transmission time stamp and the second transmission time stamp is more accurate.

Specifically, subtracting the first transmission time stamp from the second transmission time stamp is the timing transmission time length corresponding to the second timer. For example, the second transmission timestamp is 12:00:10, the first transmission timestamp is 12:00: and 10, the timing transmission duration corresponding to the second timer is 10 seconds.

S250, determining the timing position change amount of the first timer based on the first timing position information and the second timing position information.

The timing position change amount is the amount of numerical code change of the timing pointer in the first timer in the timing sending duration.

Exemplary, S250 specifically includes: and performing difference operation on the second timing position information and the first timing position information, taking an absolute value, and determining the timing position change quantity of the first timer.

Specifically, the difference operation is performed on the second timing position information and the first timing position information, and the absolute value of the difference value is taken as the timing position variation of the first timer. For example, the second timing position information is represented as N ₂ The second timing position information is denoted as N ₁ The timing position change amount of the first timer can be expressed as |n ₂ -N ₁ |。

S260, determining the unit position change amount corresponding to the unit time in the first timer based on the timing sending duration and the timing position change amount.

The position change of the first timer can be expressed as |N ₂ -N ₁ When the first transmission time stamp is t1 and the second transmission time stamp is t2, the unit position change amount corresponding to the unit time in the first timer can be expressed as

S270, multiplying the unit position change amount by the preset time in the first timer to determine the target position change amount.

In the present embodiment, how often the first device transmits data to the next-stage device is predetermined, and thus the preset timing time is a determined amount. Based on this, the unit position change amount and the preset time are determined, and then the target position change amount is obtained by multiplying the unit position change amount by the preset time. For example, the unit position change amount may be expressed as

If the preset time is 10ms, the target position change amount is +.>

S280, replacing the current position change quantity corresponding to the preset time in the first timer with the target position change quantity, and finishing the correction of the current position change quantity corresponding to the preset time in the first timer.

The preset timing time corresponding to the first device is 10ms, that is, the first device sends a secondary data message to the previous device every 10ms. For a completely new first device, the timing time of the first device is accurate, and the position change amount of the timing pointer in the first timer corresponding to the timing pointer in the first timer in 10ms time is 30. The hardware device of the first timer ages with time, and the current position change amount corresponding to the timing pointer in the first timer is 30, but the timing time corresponding to the position change amount 30 is not necessarily 10ms. At this time, the target position change amount may be determined based on the unit position change amount and the preset time in the first timer, and the current position change amount may be replaced with the target position change amount. For example, when the determined target position change amount is 40, it can be understood that the timing hand position change amount in the first timer is 40, and the time of 10ms has elapsed.

According to the technical scheme provided by the embodiment of the invention, when the unit position change amount corresponding to the unit time in the first timer is determined, the timing transmission time length corresponding to the second timer is determined firstly based on the first transmission time stamp and the second transmission time stamp, and then the position change amount of the first timer is determined based on the first timing position information and the second timing position information, so that the unit position change amount corresponding to the unit time in the first timer is determined based on the timing transmission time length and the position change amount, and the unit position change amount can be determined efficiently and accurately in this way. When the current position change amount corresponding to the preset time in the first timer is corrected, firstly, multiplication operation is carried out on the unit position change amount and the preset time in the first timer to determine the target position change amount, and then, the current position change amount corresponding to the preset time in the first timer is replaced by the target position change amount, so that correction of the current position change amount corresponding to the preset time in the first timer is completed, and accuracy of the low-performance IED timing time is further improved.

Example III

Fig. 4 is a flowchart of a method for timing time correction according to a third embodiment of the present invention, where the embodiment of the present invention uses a specific application of the first device as a support, and illustrates how the first device implements timing time correction under a normal operating condition, and the embodiment of the present invention may be combined with each of the alternatives in the one or more embodiments. As shown in fig. 4, the method includes:

s310, determining a second device which establishes communication connection with the first device, wherein a first timer in the first device does not have a timing clock correction function, and a second timer in the second device has the timing clock correction function.

S320, receiving a first message sent by the second device, and acquiring first timing position information in a first timer when the first message is received, wherein the first message comprises a first sending time stamp.

S330, receiving a second message sent by the second device based on the second timer, and acquiring second timing position information in the first timer when receiving the second message, wherein the second message comprises a second sending time stamp.

S340, determining a unit position change amount corresponding to a unit time in the first timer based on the first transmission time stamp, the second transmission time stamp, the first timing position information, and the second timing position information.

S350, determining a target position change amount based on the unit position change amount and the preset time in the first timer, and correcting the current position change amount corresponding to the preset time in the first timer based on the target position change amount.

S360, sending a data message every time the current position change amount in the first timer reaches the target position change amount corresponding to the preset timing time.

The preset timing time refers to timing time in a data message timing sending task corresponding to the first device. The timing time is used for representing how often the first device sends a secondary data message to the primary device.

In practical application, the timing sending task of the data message corresponding to the first device is first obtained, and then the timing time in the sending task of the data message Wen Dingshi is used as the preset timing time.

The timing sending task is preset and carries timing time. For example, the timing transmission task may be that the first device transmits a data packet to the previous device every 10ms, and 10ms is the timing time.

In specific implementation, the first device timing sending task may be pre-written in the execution program, and the information associated with the first device timing sending task corresponding to the data message is directly obtained through the reading instruction. Because the datagram Wen Dingshi sending task carries timing time, when the datagram timing sending task is acquired, the datagram is analyzed, so that the timing time can be acquired. After the timing time is obtained, the timing time is used as a preset timing time for subsequent correction of the timing time of the first timer of the first device.

In this embodiment, in the operation process of the first device, whenever the current position variation of the first timer is detected to reach the target position variation corresponding to the preset timing time, the first timer may trigger the data sending device of the first device, so that data is sent to the previous device, and thus, a data packet is sent at an accurate timing.

For example, if the target position change amount corresponding to the preset time is 30, when the first device sends the data packet to the previous device for the first time, the code information corresponding to the position of the timing pointer in the first timer is 1, when the current position change amount in the first timer reaches 30, that is, when the code information corresponding to the position of the timing pointer in the first timer is 31, the first device sends the data packet to the previous device for the second time, and the subsequent timing sending tasks are all that when the current position change amount in the first timer reaches 30, the first device sends the first data packet to the previous device.

According to the technical scheme provided by the embodiment of the invention, after the current position change amount corresponding to the preset time in the first timer is corrected, the timing time in the data message Wen Dingshi sending task is used as the preset time by acquiring the data message timing sending task corresponding to the first device, and then a data message is sent for a certain time each time the current position change amount in the first timer reaches the target position change amount corresponding to the preset time.
