It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one

and 110, sequentially acquiring switch data acquired by a plurality of intelligent power monitoring devices arranged in the transformer substation in a polling mode, and acquiring an initial object consisting of a plurality of power switch sequences.
In the embodiment of the invention, each intelligent power monitoring device corresponds to a power device, each power device is provided with a plurality of power switches, the switch data comprises the states of the power switches, and each power switch sequence further comprises the number of the corresponding intelligent power monitoring device. That is, the states of the power switches under one smart power monitoring device constitute a group of power switching sequences, and the numbers of the smart power monitoring devices are also included in the power switching sequences, and then the power switching sequences collected by a plurality of smart power monitoring devices collectively constitute the initial object in the embodiment of the present invention.
The electric power system is an electric energy production and consumption system which consists of links such as a power plant, a power transmission and transformation line, a power supply and distribution station, power utilization and the like. The function of the device is to convert the primary energy of the nature into electric energy through a power generation device, and then supply the electric energy to each user through power transmission, power transformation and power distribution. In order to realize the function, the power system is also provided with corresponding information and control systems at each link and different levels, and the production process of the electric energy is measured, regulated, controlled, protected, communicated and scheduled so as to ensure that users obtain safe and high-quality electric energy. The main structures of the power system include a power source (power plants such as hydropower stations, thermal power plants, and nuclear power plants), a substation (a step-up substation, a load center substation, and the like), a power transmission and distribution line, and a load center. The power supply points are also mutually connected to realize the exchange and regulation of electric energy among different regions, thereby improving the safety and the economical efficiency of power supply. The information and control system of the power system is composed of various power devices (detection devices, communication devices, safety protection devices, automatic control devices, monitoring automation systems and dispatching automation systems). The power equipment includes a large number of power switches, and the normal operation of the power equipment is controlled by the on and short circuit states of the power switches. An intelligent power monitoring device ied (intelligent Electronic device) can be used for monitoring the operating state of the switchgear of the substation. The collection of the state of the power switch can be judged by collecting the on-off condition of the corresponding circuit through the intelligent power monitoring device.
In the embodiment of the present invention, the polling acquisition power switch sequence may be performed at a preset time interval, where the preset time interval refers to a preset time interval, and the time interval may be set manually or determined by parameters of the acquisition device itself. For example, the time interval is manually set according to the specific operation condition of the power equipment, and the time interval for collecting the on-state and the off-state of the power switch each time is determined, and for example, the time interval may be set to 1S, 10S, 1min, and the like. The time interval of the acquisition may also be a time interval of the acquisition according to the sampling rate of the acquisition device itself, and the specific time interval is not limited herein and may be adjusted or set according to actual needs.
In a particular implementation, a plurality of power switching sequences are included in the initial object, and a number of a corresponding smart power monitoring device and status information of the corresponding power switch are included in each power switching sequence. Secondly, in the embodiment of the invention, the state acquisition of the power switch also follows a certain sequence, so that the state of the power switch is ensured to be arranged in a fixed sequence every time, and data errors caused by disordered positions and states of the power switch are avoided. Next, a specific code can be set in the switching sequence to indicate the on state and the off state, for example, the number "0" indicates the off state, and the number "1" indicates the on state. Alternatively, the on state and the off state may be indicated by other numbers, characters, or the like. The switching sequence of the power switch is mainly used for distinguishing the on-off state of the power switch.
And step 120, performing verification calculation on the initial object and a preset reference object.
In the embodiment of the invention, the state change of the power switch is monitored, so that the state of the power switch can be continuously collected, and a plurality of groups of switch sequences can be generated according to different collection times. Since the power switch of the power equipment is monitored in real time, the newly acquired first switching sequence can be compared with the second switching sequence acquired at the previous moment to judge whether the state of the current power switch is changed. In other non-real-time monitoring systems, standard data of reference objects can be set according to needs, or multiple groups of reference objects are set according to the working state of the transformer substation, and the corresponding reference objects are selected according to the actual working state during actual judgment.
In a specific implementation, a verification calculation of data change is performed on the power switching sequence by taking the reference object as a reference, and whether the power switching sequence is changed relative to the reference object is determined. Specifically, the adopted calibration calculation method can be selected according to actual needs, for example, the two groups of switch sequences are calculated by using a bit exclusive or, a hash value calculation, a subtraction method, and the like, and whether the power switch sequence is changed relative to the reference object is judged. Or matching corresponding sequence characteristics in the reference object according to the numbers of the electronic switches in the power switch sequence, and comparing the states of the electronic switches corresponding to the numbers with the corresponding sequence characteristics in the reference object to determine. The check bits of different power switch sequences can be checked to check whether the power switch sequences are consistent with the reference power switch sequence. The specific check calculation method is many, and is not limited to this, and may be selected according to a specific computing device in an actual implementation.
Step 130, determining the changed power switch sequence in the initial object as the target object based on the result of the verification calculation.
In the foregoing step 120, the consistency between the target object and the reference object is verified, and in this step, the power switch sequence that has changed from the reference object in the initial target collected at the current time may be determined according to the result of the verification calculation, so as to determine the target object of the data of all the changed power switches.
And 140, uploading the target object to the power terminal equipment.
In a specific implementation, when the state of the power switch is determined to be changed, the current state information of the power device needs to be uploaded to the power terminal device, so that the power terminal device further determines the state of the power device according to the state information of the power device to make a corresponding response.
The technical scheme of the embodiment acquires the serial number of the intelligent power monitoring device and the state of the corresponding power switch under the intelligent power monitoring device, thereby obtaining the power switch sequence with the serial number of the intelligent power monitoring device, realizing the simultaneous monitoring of a plurality of power devices and a plurality of power switches at one time, conveniently realizing the acquisition and the positioning of the power switches by correlating the state of the power switches with the serial number of the intelligent power monitoring device, determining the specific changed power switches by the serial number and the sequencing of the power switch sequence at the later stage, uploading the changed power switch sequence to the power terminal device after determining the change of the state of the power switches of the power devices, further realizing the determination and calculation of the state of the power switches originally realized by the power terminal device and transferring the state determination and calculation to the power switch management device, and effectively reducing the calculation amount of the power terminal device, the resource requirement on the power terminal equipment is reduced, the influence of data errors possibly brought in the process of transmitting a large amount of data on the judgment error of the power switch of the power equipment can be effectively avoided, and the reliability of monitoring the power switch of the power equipment is improved.
Example two
Fig. 2 is a flowchart of a power switch management method according to a second embodiment of the present invention, which is based on the foregoing embodiments and further refines the verification calculation performed on the power switch sequence and the preset reference switch sequence.
The method specifically comprises the following steps:
step 201, sequentially collecting switching data of the intelligent power monitoring device in a polling mode according to a preset time interval, and obtaining an initial object which is composed of the number of the intelligent power monitoring device and '0' or '1' corresponding to the state of the power switch.
In the embodiment of the invention, the states of the power switch comprise an open state and a closed state, wherein 0 is used for representing the open state, and 1 is used for representing the closed state. The numbers "0" and "1" are only one specific example, and other numbers or letters may be used instead in other embodiments.
In a specific implementation, the power switches of the power equipment may be sorted according to a preset order, then state acquisition is performed on all the power switches according to the sorting, then a sequence with a specified length corresponding to the state is generated, and finally the serial number of the intelligent power monitoring device is added to the sequence to form the power switch sequence in the embodiment of the present invention. For example, a power device has 10 power switches, the 10 power switches are numbered and sorted according to the numbers 0 to 9, then the states of the 10 power switches are obtained according to a preset time interval, a sequence similar to the form of "1101001010" is generated according to the sorting, and then a code corresponding to the number of the intelligent power monitoring device is added to the head or the tail of the sequence, so as to combine the power switch sequences in the embodiment of the invention. Wherein the code may be a combination of numbers or letters of a particular length.
In an embodiment of the present invention, the initial object obtained from the previous collection is set as the reference object, that is, in this embodiment, the monitoring of the power switch is to monitor whether the power switch is changed, and the determination criterion is to compare the state of the power switch at the current time with the state of the power switch at the previous time to determine whether the power switch is changed. Therefore, in this embodiment, the initial object acquired last time is set as the reference object.
In other embodiments, a fixed reference object may be directly set, or different reference objects may be set according to different operating states of the power devices of the substation, and after the power objects are verified, the corresponding reference objects are directly matched according to the operating states of the power devices of the substation, and then specific verification is performed.
Step 202, performing bitwise exclusive-or operation and/or hash operation on the initial object and a preset reference object.
The exclusive-or operation is a mathematical logic operation mode, and is mainly applied to logic operation. If the two values are not the same, the XOR result is 1. If the two values are the same, the XOR result is 0. The value of the exclusive-or operation is true only if the value of exactly one of the two operands is true and the value of the other one is not.
In the embodiment of the present invention, the bitwise xor operation refers to performing xor operation on values of the same number of bits of the power switch sequence and the reference switch sequence to obtain the first check value. For example, if the power switching sequence and the reference switching sequence are both 10101, the corresponding first check value is 00000; when the reference switching sequence is different from the power switching sequence, for example, the reference switching sequence is 11001, the first check value is 01100, where the second bit and the third bit in the reference switching sequence are different from the power switching sequence, so the value of the second bit and the third bit of the calculated first check value is 1. In addition, when the elements in the power switch sequence are subjected to bitwise exclusive-or operation, the numbers can be matched firstly, namely, the corresponding reference switch sequence elements are determined according to the power switch sequence, so that errors caused by the fact that the sequence of the power switch sequence is inconsistent with the sequence of the reference switch sequence are avoided.
Hash operations (Hash) are the conversion of an input of arbitrary length (also called a pre-mapped pre-image) into a fixed-length output, known as a Hash value, by a hashing algorithm. This transformation is a kind of compression mapping, i.e. the space of hash values is usually much smaller than the space of inputs, different inputs may hash to the same output, so it is not possible to determine a unique input value from a hash value. In short, it is a function of compressing a message of an arbitrary length to a message digest of a certain fixed length. The hash operation may convert a data into a token that is closely related to each byte of the source data.
In this embodiment, a unified hash algorithm is applied to the power switch sequence and the reference switch sequence to perform hash calculation, so as to obtain corresponding hash values, respectively, and the consistency check of the two switch sequences can be realized by comparing whether the two hash values are consistent, that is, whether the power switch sequence is changed relative to the reference switch sequence is determined.
Step 203, determining whether the initial object changes according to the result of the check calculation;
in the foregoing step 202, a verification calculation is performed on the consistency between the power object collected at the current time and the reference object, and in this step, whether the power object is consistent with the reference object may be determined according to a result of the verification calculation, so as to determine whether the state of the power switch is changed, and after the state of the power switch is changed, a corresponding operation is performed.
When the initial object changes from the referenced object, executing step 204;
when the initial object has not changed from the referenced object, step 205 is performed.
And step 204, determining the power switch sequence of the initial object changed relative to the reference object as the target object according to the bitwise exclusive-or operation.
What is needed in this step is to determine the element of the electric power object that changes relative to the reference object after determining that the electric power object changes relative to the reference object based on the result of the verification calculation. The execution of the bitwise xor operation is only a specific operation manner, and may also be to obtain a changed element based on a result of the check calculation, for example, when the check calculation adopts a bitwise xor operation or a bitwise addition and subtraction method, etc., it may directly determine the changed element, at this time, it is not necessary to separately determine the changed element by the bitwise xor operation, and besides the bitwise xor operation, a bitwise addition and subtraction method, a bitwise hash operation, etc., may also be used for the determination.
Step 205, storing the initial object to the storage unit, and setting the initial object as the reference object.
In the embodiment of the invention, when the state of the power switch is not changed, the collected initial object data of the power switch is stored in the storage unit, so that the calling of the initial object data at the later stage can be facilitated.
And step 206, uploading the target object to the power terminal equipment.
In a specific implementation, in the foregoing steps, a power switch sequence in which all power objects change from a reference object is confirmed, that is, a changed power switch in a substation is determined, and then change information of the power switch needs to be packaged and uploaded. The packing manner may be various, for example, all the target power switch sequences are packed into a set as mentioned in step 204, and the set is sent to the power terminal device, or the data of the corresponding intelligent power monitoring device, the power device, or the substation within a period of time is integrally packed and uploaded on the basis of the target set. The specific uploaded data content can be changed correspondingly according to actual needs.
And step 207, timing the length of the first time period.
And step 208, uploading the initial object collected in the first time period to the power terminal equipment when the initial object is not changed relative to the referenced object in the first time period.
In the embodiment of the invention, the collected data are stored when the state of the power switch is not changed, and the data in the first time period are uniformly packed and uploaded to the power terminal equipment for subsequent processing when the state of the power switch is not changed in the first time period. When the state of the power switch changes within the first time period, partial data which are not uploaded can be uploaded timely, so that the power terminal equipment can further judge the actual situation, and the normal operation of the intelligent substation is guaranteed.
