Description

A temporary switch box system for substation infrastructure and its monitoring method

Technical field

The invention belongs to the technical field of switch boxes, and specifically relates to a temporary switch box system used in substation infrastructure and a monitoring method thereof.

Background technique

Temporary switch boxes are often used in substation infrastructure. Temporary switch boxes temporarily assemble switching equipment, measuring instruments, protective appliances and auxiliary equipment in closed or semi-closed metal cabinets or screens according to electrical wiring requirements to form a low-voltage switch box. . During normal operation, the circuit can be connected or disconnected with the help of a manual or automatic switch. When there is a fault or abnormal operation, the circuit is cut off or the alarm is generated by using protective equipment. Measuring instruments can display various parameters during operation, adjust certain electrical parameters, and provide prompts or signals for deviations from daily working conditions.

In specific applications, the electrical data collection of the switch box for monitoring the temporary switch box is mainly through the patent number "202211400348.0" and the patent name is "A multi-channel detection arc light protection system for vcs isolation switch box" As described in the existing technical solution, the electrical data of the switch box is collected from the temporary switch box at the substation infrastructure site through the transmitter equipment, and then the electrical data of the switch box is transmitted to the data center.

In this way, the transmitter equipment and the data center will be connected wirelessly; the TFTP standard is often used to transfer switch box electrical data between the transmitter equipment and the data center. The TFTP standard does not have instructions for link interaction, and can be achieved in one round of transmission. The switch box electrical data transmission does not automatically ask the data center to automatically respond to the switch box electrical data transmitted by the transmitter device, which will save resource consumption; because of this, the transmitter device also allows the transmitter device to transmit data The electrical data transmission effect of the central switch box cannot be understood; and current wireless transmission is affected by various factors (such as factors such as wireless facility maintenance and magnetic field disturbance); in addition, depending on the performance of the wireless network, the synchronization of one loop into the wireless The number of transmitter devices in the network is usually twelve. The higher the number of transmitter devices connected to the wireless network, the higher the probability of transmission failure due to collision of electrical data transmission in the switch box, which cannot ensure that each The electrical data of the switch box transmitted from the secondary transmitter device to the data center is correctly obtained; and to improve the security of transmission, the current common method is to automatically respond to the identification in the process of the data center to improve the security of transmission. However, this This method increases the response waiting time of the transmitter device, which will increase resource consumption and increase the transmission volume.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely expressed below in conjunction with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only part of the embodiments of the present invention, rather than all embodiments. Based on the spirit of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in Figure 1, a monitoring method for a temporary switch box system used in substation infrastructure according to the present invention includes:

Step 1: The transmitter collects the electrical data of the switch box from the temporary switch box at the substation infrastructure site and transmits it to the controller;

Step 2: The controller transmits the collected electrical data of the switch box to the data center. The value of the electrical data of the switch box is the electrical value;

As shown in Figure 3, step 2 specifically includes:

In step 2-1, the controller of the transmitter device transmits an activation message for the value corresponding to the electrical data of the switch box, that is, the electrical value (the transmission activation message can be transmitted from the data center to the controller of the transmitter device) , the destination value message is formed based on the number of values and the current filling value of the value message to be used. Here, the value message to be used contains a value field, the value field is used to fill the electrical value, and the number of values includes the transmission period (the The period can be the number of electrical values in the period collected during the time period), and the current filled value contains the value of the idle value field in the unused value message; in step 2-2, the controller of the transmitter device The destination value message is delivered to the corresponding data center; in step 2-3, if the destination value message meets the response rules, the controller of the transmitter device receives the response identification message corresponding to the destination value message transmitted by the data center. ; Otherwise, the data center does not send a response assertion message to the controller of the transmitter device.

In the present invention, the controller of the transmitter device detects the received electrical value at a set time interval (eg, 1 minute or 2 minutes, etc.); Deliver a value message to the corresponding data center within a certain delivery period (e.g., 2 seconds, etc.). So step 2 specifically includes:

Step 2-1: The controller of the transmitter device activates the transmission message corresponding to the electrical value, and forms a destination value message based on the number of values and the current filled value of the value message to be used;

In a specific implementation, the value message to be used includes a value field. The value field is used to fill in the electrical value. The number of values includes the number of electrical values in the period collected during the transmission period (the period can be a timing period). , the current fill value contains the values of the idle value fields in the value message to be used.

In the present invention, the transmission activation message includes a separate transmission time interval (just as the controller of the transmitter device transmits a value message to the corresponding data center every 2 seconds. Of course, the above 2 seconds is just an example. Just as, It can be 2.5 seconds or 1 second, etc.), and the electrical value within the period contains the prompt message identification code (just like, when the controller of the transmitter device detects that the electrical value within the collected period contains the prompt identification code, it is activated to form a target value report. text, to be transmitted to the data center in real time); in the present invention, the transmission period includes constant periods including 1 second, 2.5 seconds, etc.; in the present invention, when the electrical value within the period contains the prompt identification code, the transmission period includes the detection of the prompt The time interval between the identification code time and the time when the value message was last transmitted. In the present invention, the electrical value within the time period includes the electrical value received (collected) during the transmission time period; in the present invention, the electrical value includes the electrical value within the time period and the retransmission value. In the present invention, the value message to be used includes the value message in the past (just as the value message in the past includes the value message that has been transmitted to the data center, but has not received the response confirmation message); in the present invention, the value message to be used in the present invention is The numerical message contains a new numerical message that is updated as a whole (just like the numerical message formed for the first time, that is, the new numerical message is not formed based on the previous numerical message); in the present invention, the changed numerical message In order to transmit the activation message, the controller of the transmitter device forms a destination value message based on the number of values and the current filling value of the value message to be used. For example, if the number of electrical values in the period collected during the transfer period is not higher than the value in the idle value field, the electrical values in the period collected in the transfer period are regarded as the electrical values in the destination period, and the entirety is filled in In the value message to be used, the destination value message is formed; the formation process corresponding to the destination value message will be described later; in the present invention, the maximum transmission amount of the controller of the transmitter device at one time (usually 2 to ¹⁰ bytes ) is determined by the wireless module; in the present invention, in order to transmit the activation message, the controller of the transmitter device forms a destination value message based on the number of values and the current filling value of the value message to be used, and converts the destination value message into Pass it to the data center to complete the service of delivering the destination value message.

In other words, each delivery of the activation message only corresponds to the business of delivering the destination value message to the data center once.

Step 2-2: The controller of the transmitter device transmits the destination value message to the corresponding data center;

Just like, after forming the destination value message, the controller of the transmitter device transmits the destination value message to the corresponding data center to perform the transmission of electrical values;

Step 2-3: If the destination value message conforms to the response rules, the controller of the transmitter device receives the response confirmation message corresponding to the destination value message transmitted by the data center; otherwise, the data center does not respond to the response request of the transmitter device. The controller delivers the response assertion message.

In the present invention, only when the destination value message conforms to the response rules, the data center can send back the response identification message to the controller of the transmitter device. If the destination value message does not comply with the response rules, the data center will not change the direction. The controller of the transmitter device sends back a response identification message. In a specific implementation, upon receiving the destination value message in response to the identification message, the controller of the transmitter device clears the copy of the destination value message (the copy is a copy of the destination value message). file) to clear the controller storage unit; for the destination value message that has not received the response identification message, the controller of the transmitter device will store a copy of the destination value message in the controller as a previous value message. , is used as the standby value message in the next delivery period, and continues to form the destination value message. When the delivery activation rules are met, the destination value message is formed based on the previous value message and is re-delivered to the data center.

In a specific implementation, the response rules are:

The number of electrical values filled in the destination value message is the critical quantity; in the present invention, the critical quantity can be four, five or six; just like, if the data center detects that the destination value message is sufficient (Just as the number of electrical values in the destination value message is the critical number), the data center transmits a response identification message to the controller of the transmitter device; in the present invention, by setting the response rule, an electrical The value will be transmitted up to a critical number of times (for example, with a critical number of five, an electrical value will be transmitted up to five times), while improving transmission security, reducing the impact on the controller of the transmitter device due to receiving the value The resulting resource consumption.

The response rule can also be: the electrical value within the period filled in the destination value message contains the prompt message identification code;

In the present invention, for electrical values (such as prompt messages) with high immediacy standards for data transmission, the controller of the transmitter device is activated to form a destination value message, which is suitable for transmitting the destination value message in real time. to the data center; the second will also activate the data center to send back a response identification message to the controller of the transmitter device; for example, when the controller of the transmitter device detects that the electrical values collected during the period contain a prompt message identification code When the data center detects that the destination value message contains the prompt message identification code, it will send a response identification message to the controller of the transmitter device.

The response rule can also be: the destination value message contains the identification code message to be responded to. Just like, the controller of the transmitter device can also detect whether the destination value message meets the number of electrical values filled in the destination value message or the electrical value within the period filled in the destination value message. The value contains a prompt message identification code; if the controller of the transmitter device detects that the number of electrical values in the destination value message is a critical number, or the electrical value within the period filled in the destination value message contains a prompt message identification code, then the controller of the transmitter device adds the identification code message to be responded to in the destination value message. When the data center detects that the destination value message contains the identification code message to be responded to, the data center will The controller of the device transmits a response identification message; in the present invention, the number of electrical values in the destination value message detected by the data center is the critical quantity, or the electrical value within the period filled in the destination value message contains When the message identification code is prompted, the controller of the transmitter device is set to have a response waiting time limit after each transmission of the destination value message. After receiving the response identification message during the response waiting time limit, the control unit of the transmitter device The transmitter switches to a standby state; in the present invention, when the controller of the transmitter device detects the number of electrical values in the destination value message, it is a critical number, or is filled in the period of time in the destination value message. When the electrical value contains the prompt message identification code, the controller of the transmitter device has a response waiting time limit (for example, 15 seconds) only when the response rule contains the destination value message and the identification code message to be responded to. The controller of the device can still receive messages delivered by the data center (such as response confirmation messages) during the response waiting time limit, and will enter a standby state after receiving the response confirmation message during the response waiting time limit.

In a specific implementation, the electrical values are sequentially filled in the value message according to the collection (receiving) time.

In a specific implementation, the method of forming a destination value message based on the number of values and the current padding value of the value message to be used includes:

If the number of values is not higher than the number of idle value fields, the electrical values in the period collected during the transmission period are regarded as the electrical values in the destination period, and the entire electrical value in the destination period is filled into the unused value message. The corresponding idle value field is used to form the destination value message; on the contrary, the electrical value in the destination period is determined from the electrical values in more than one period collected in the transmission period and the value is retransmitted, and the electrical value in the destination period is filled in The corresponding idle value field in the pending value message is used to register the retransmitted value in the log file. In the present invention, the electrical values in the numerical message are arranged and filled in the corresponding numerical fields in order according to the collection time, so as to facilitate the controller of the transmitter device to determine the collection time of each electrical value in the numerical message; just like, When determining the target past value among more than one past value in a past value message, it is enough to send it according to the arrangement order of more than one past value; just like more than one past value, one side of the past value message reaches On the other side (just like, from the front to the back, the collection time of the frontmost previous value is the first), it is arranged in order according to the collection time. When the electrical value has an idle value field in the period, the corresponding number is sent through the frontmost execution movement. Past values can be used to free up the electrical values in the value field filling period; just like, if the number of electrical values in the period collected in the delivery period is not higher than the number of idle value fields in the unused value message , just fill in the corresponding idle value fields with the electrical values collected during the transmission period (just like filling in the corresponding idle value fields in order according to the collection time of the electrical values in each period); if this If the number of electrical values in the time period collected during the transmission period exceeds the number of idle value fields, the electrical value in the destination period and the retransmission value must be determined from the electrical values in more than one time period collected in the transmission period. Fill the electrical value in the target period into the corresponding idle value field in the value message to be used, and register the retransmitted value in the log file; in the present invention, the controller of the transmitter device will register the collection of each electrical value collected Time, just like when the controller of the transmitter device registers the retransmitted value in the log file, it will register the collection time of the retransmitted value. It is suitable for later filling in the retransmitted value from the log file based on the collection time. Determine the purpose within and then pass the value.

In a specific implementation, if the number of values is lower than the number of idle value fields, the electrical values in the period collected in the transfer period are regarded as the electrical values in the destination period, and the electrical values in the destination period are filled in as a whole to the waiting period. The method of using the corresponding idle numerical fields in the numerical message to form the destination numerical message includes: if the number of values is lower than the number of idle numerical fields, the electrical values collected during the transmission period are regarded as the destination. The electrical value within the time period, and the entire electrical value within the destination period is filled into the corresponding idle value field in the waiting value message; if there is more than one retransmission value in the log file, more than one retransmission value will be processed based on the collection time of each retransmission value. Determine the destination retransmission value within the transmission value. Here, the collection time of the destination retransmission value is later than the collection time of other retransmission values; fill the destination retransmission value into the corresponding idle value field in the unused value message to form Destination value message. As such, the retransmitted electrical values in the log file contain electrical values that have not been previously transferred to the data center. Just like, when the number of electrical values in a period is lower than the number of idle value fields, it is also necessary to search the log file to see if there are any re-transmitted values. If there are re-transmitted values, it will be judged by more than one re-transmitted value. The destination retransmission value is used to fill the destination retransmission value into the corresponding idle value field, so that the formed destination value message can be in a sufficient state; in the present invention, the collection time of the retransmission value precedes the collection of the electrical value within the period. time, so when filling the destination retransmission value, the destination retransmission value is on the side where the electrical value collection time is first within the period; just like, if in the waiting value message, from front to back, the collection time is closer in order At the current time, then the destination retransmission value is in front of the electrical value within the period; in the present invention, the destination retransmission value can be determined arbitrarily within more than one retransmission value; in the present invention, the destination retransmission value can also be determined through more than one retransmission value based on the collection time. Determine the destination retransmission value within the value. Here, the collection time of the destination retransmission value is later than the collection time of more than one retransmission value and other retransmission values.

In a specific implementation, the value message to be used contains a value message in the past period, the transmission time of the value message in the past period is earlier than the transmission period, and the value message in the past period contains more than one idle value field and more than one value message in the past period. value; on the contrary, determine the electrical value in the destination period and retransmit the value from the electrical values in more than one period collected in the transmission period, and fill the electrical value in the destination period into the corresponding idle value field in the destination value message. The method of registering the retransmission value in the log file includes: if the number of values is higher than the number of idle value fields and higher than the number of all value fields in the previous value message, sending more than one past value to the period value message, and register it in the log file as a retransmission value; determine the electrical value in the destination period and the retransmission value based on the electrical values in more than one period; fill the entire electrical value in the destination period into the previous period value message The corresponding idle value field; register the retransmitted value in the log file; if the number of values is higher than the number of idle value fields and lower than the number of all value fields of the unused value message, after more than one previous period Determine the target past value in the value, send the target past value out of the past value message, and fill the electrical value in the target period into the value field corresponding to the target past value. Here, the collection time of the target past value precedes The collection time of additional past values within more than one past value. Just as the value message to be used contains the value message of the past period, in the present invention, the value message of the past period contains the value message that has been transmitted to the data center, but the response confirmation message has not been received. In the present invention, the transmitter The controller of the device will temporarily store a copy of the numerical message. When the controller of the transmitter device transmits the numerical message to the data center, but does not receive a response confirmation message for the numerical message, it will continue to store the value. A copy of the message, and regard the copy as a past value message. When the next delivery activation rule is met, the destination value message is formed based on the past value message and delivered to the data center. Just as, to be The numerical message contains past value messages. In the present invention, the past value message contains more than one idle value field and more than one past value. In the transmission period, the number of electrical values collected in the period is high. When the number of idle value fields exceeds, there will be two types of situations. One is that the number of electrical values in a period is higher than the number of idle fields, and is higher than the number of all value fields in the previous value message. At this time, all the previous values in the previous value message are sent out as the previous value message, and the electrical value in the target period is determined based on the electrical value in the period and the value is transmitted again; in the present invention, the transmitter The controller of the equipment determines the electrical value in the target period and the retransmitted value based on the collection time of the electrical value in more than one period; just like, the electrical value in the latest collected period is determined as the electrical value in the target period; the other type is, within the period The number of electrical values is higher than the number of idle value fields and lower than the number of all value fields in the past value message. In this case, it must be determined by more than one past value in the past value message. The destination past value; sending the destination past value message as a past value message, it is suitable to fill the electrical value in the destination period to the corresponding place of the destination past value. Here, the collection time of the destination past value precedes more than one The collection time of other past values in the past value; in the present invention, the electrical values are arranged in order according to the collection time in the value message. Therefore, when the target past value is sent, it can be filled in first The past value on one side of the past value message is selected, and the number of past values to be sent is used as the target past value.

In a specific implementation, the method of determining the electrical value in the destination period and the retransmission value through the electrical value in more than one period includes: based on the collection time of the electrical value in each period within the electrical value in more than one period, through more than one period The internal electrical value determines the electrical value in the destination period and the retransmission value. Here, the collection time of the retransmission value is earlier than the collection time of the electrical value in the destination period. In the present invention, to ensure the immediacy of the values, the controller of the transmitter device fills in the latest collected electrical values during the period and transmits them to the data center; just as the controller of the transmitter device registers its collection The collection time of each electrical value in the electrical value in more than one time period; when determining the electrical value in the target period and the retransmission value from the electrical value in more than one time period, based on the collection time of the electrical value in each time period in the electrical value in more than one time period, after more than one time period The electrical value in the time period is determined from the electrical value in the target time period and the retransmission value. Here, the collection time of the retransmission value is earlier than the collection time of the electrical value in the target time period.

In a specific implementation, the value message to be used also contains a time point field. The time point field is used to fill the time point. The time point contains the base time point or the destination sequence code. If the value message to be used contains previous value messages, The destination reference time point of the destination value message can be determined through the following calculation formula:

In the formula, As the target reference point,/> It is the first base time point in the past period of the first previous period numerical message corresponding to the destination numerical message,/> It is the destination sequence code of the destination numerical message,/> is the delivery period size.

In the present invention, when the value message to be used contains a previous value message, the time point in the previous value message only contains the destination sequence code; when the value message to be used contains a new value message, the time point in the new value message The time point includes the base time point in the destination sequence code; just as it is necessary to fill in a larger amount of electrical values, and by reducing the time point, a value message can contain a larger number of additional valid values; this method In the invention, the time point of the new value message includes the base time point (for example, seventeen o'clock on March 2, 2023) and the destination sequence code (for example, zero). If the controller of the transmitter device sends the new After the value message was transmitted to the data center, no response confirmation message was obtained from the data center (for example, the new value message was not sufficient and there was an idle value field); the controller of the transmitter device copied the new value message The file is stored on the controller as the first past value message; just as the first past reference time point of the first past value message includes March 2, 2023; when the delivery activation rules are met again , the controller of the transmitter device forms the destination value message based on the number of values and the current filling value of the value message to be used (for example, the previous value message), then the time point of the destination value message only contains the destination value. The sequence code (just as one) reduces the capacity at the time point through the destination sequence code, so that a value message can be maximized to the value field to fill a larger amount of electrical values; just like the first previous benchmark The time point includes 17:00 on March 2, 2023, the destination sequence code is 1, and the delivery period size is 2 seconds, then the target base time point is two seconds after 17:00 on March 2, 2023 .

In the present invention, the destination sequence code of the first past value message is zero, and the destination sequence code of the second past value message formed by using the first past value message as a standby value message is one, using The second past value message is regarded as the destination sequence code of the third past value message formed by the standby value message. According to the same derivation, the destination value message formed during this transmission period can be registered. Target sequence code.
