[0084] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0085] The solution of the present application may be implemented based on a terminal having data processing capabilities, the terminal may be a software comparison system, and the software comparison system may have a device slot.

[0086] The device bit slot may include a first device bit, a second device bit, a third device bit and a fourth device bit, and the first device bit, the second device bit and the third device bit may all communicate with the fourth device bit.

[0087] Each device bit of the device bit slot can communicate through the serial port, such as the communication serial port of the first device bit is COM3, the communication serial port of the second device bit is COM6, the communication serial port of the third device bit is COM3, and the communication serial port of the fourth device bit is COM1. The baud rate of the device bit can be 9600.

[0088] Specifically, the first device position can be used to store the prototype for filing, the second device position can be used to store the prototype storing the correct program, the third device position can be used to store the prototype storing the incorrect program, and the fourth device position can be used to store the device that needs to be compared.

[0089] Next, combine Figure 1 The software comparison method of the electric power equipment of the present application may include the following steps:

[0090] Step S110: When the fourth device position is equipped with an electric device, a software filing comparison file of the electric device is obtained, and the software filing comparison file is entered into a preset filing entry system, and a filing information file is exported.

[0091] Specifically, the preset filing and entry system may have a filing and entry program, and the data format of the filing and entry program may be in .exe format. The software filing comparison file is input into the filing and entry program, and a filing information file may be output, and the data format of the filing information file may be in xml format.

[0092] It is understandable that the fourth device position is for placing equipment that needs to be compared, so when the power equipment is installed in the fourth device position, the software filing comparison file of the power equipment can be obtained.

[0093] The power equipment may store multiple software to realize the functions corresponding to each software, and each software may have model information and type information of the software. The filing information file may include a filing number.

[0094] Step S120: extracting the registration number of the electric power equipment from the registration information file.

[0095] It is understandable that the registration number is the unique ID of the power equipment. When it is necessary to query the relevant equipment or files of the power equipment, the registration number of the power equipment can be used for indexing.

[0096] Step S130: Based on the filing number, a filing prototype of the power equipment during software filing is set at the first device position, a correct program prototype of the power equipment is set at the second device position, and an incorrect program prototype of the power equipment is set at the third device position.

[0097] The correct program prototype may store a correct operating program of the electric equipment, and the incorrect program prototype may store an incorrect operating program of the electric equipment.

[0098] It is understandable that by indexing through the registration number, it is possible to determine the registered prototype of the power equipment when the software is registered, as well as the correct program prototype of the power equipment and the incorrect program prototype of the power equipment.

[0099] Step S140: Determine the comparison file format type and comparison configuration parameters of the filing information file.

[0100] Specifically, the comparison file format type and the comparison configuration parameters are environmental parameters of the power equipment when performing program comparison.

[0101] The comparison configuration parameters may include a power source communication serial port (such as COM1), an electric meter voltage (such as 220V) and a control unit communication serial port (such as COM8). The comparison file format type of the filing information file may be an easm format type.

[0102] Step S150, under the comparison file format type and comparison configuration parameters, perform a prototype program comparison between the fourth device bit and the first device bit to obtain a first software comparison result, perform a prototype program comparison between the fourth device bit and the second device bit to obtain a second software comparison result, and perform a prototype program comparison between the fourth device bit and the third device bit to obtain a third software comparison result.

[0103] Specifically, the first software comparison result may represent the comparison result of the function implemented by the running program of the power equipment and the function implemented by the running program of the retained prototype. The second software comparison result may represent the comparison result of the function implemented by the running program of the power equipment and the function implemented by the running program of the correct program prototype. The third software comparison result may represent the comparison result of the function implemented by the running program of the power equipment and the function implemented by the running program of the incorrect program prototype.

[0104] Step S160: When the first software comparison result, the second software comparison result and the third software comparison result are all qualified, it is determined that the software function of the power equipment is normal.

[0105] In addition, when at least one of the first software comparison result, the second software comparison result and the third software comparison result is unqualified, it is determined that the software function of the power equipment is abnormal.

[0106] The hardware comparison method of the electric power equipment provided in the present embodiment obtains the software filing comparison file of the electric power equipment when the electric power equipment is installed on the fourth equipment position of the software comparison system, enters the software filing comparison file into a preset filing entry system, exports a filing information file, extracts the filing number of the electric power equipment from the filing information file, and sets the filing prototype of the electric power equipment at the time of software filing on the first equipment position based on the filing number, sets the correct program prototype of the electric power equipment on the second equipment position, and sets the wrong program prototype of the electric power equipment on the third equipment position, wherein the correct program prototype stores the correct running program of the electric power equipment, and the wrong program prototype stores the wrong running program of the electric power equipment. The prototype stores the running error program of the electric power equipment, determines the comparison file format type and the comparison configuration parameters of the filing information file, compares the prototype program of the fourth device bit with the first device bit under the comparison file format type and the comparison configuration parameters, obtains the first software comparison result, compares the prototype program of the fourth device bit with the second device bit, obtains the second software comparison result, and compares the prototype program of the fourth device bit with the third device bit, obtains the third software comparison result, and when the first software comparison result, the second software comparison result and the third software comparison result are all qualified, it is determined that the software function of the electric power equipment is normal. It can be seen that by comparing the prototype program of the reserved prototype, the correct program prototype and the error program prototype with the electric power equipment one by one, it can be identified whether the software of the electric power equipment is running normally, thereby ensuring that the software function of the electric power equipment used by the power grid is normal and meeting the requirements of safe and reliable operation of the electric power equipment.

[0107] In some embodiments of the present application, the software filing process of the power equipment mentioned in the above embodiments is introduced. The software filing process can be performed when the power equipment does not have a software comparison function, such as Figure 2 As shown, the software filing process may include:

[0108] Step S210: After the hardware of the power equipment passes the comparison test, a software function test is performed on each software of the power equipment to obtain a software test result of each software.

[0109] Specifically, the hardware information of the power equipment can be obtained from the supplier of the power equipment, and a hardware comparison test can be performed on the power equipment. If the hardware of the power equipment passes the comparison test, a software function test can be performed on each software of the power equipment to obtain the software test results of each software.

[0110] Step S220: If the software test results of each software are qualified, the software filing information of the power equipment is obtained.

[0111] Among them, the software test results of each software are qualified, which means that the software of the power equipment has not been modified.

[0112] Specifically, after the software test results of each software are qualified, the software filing information of the power equipment can be sampled and electronically sealed to start filing.

[0113] Furthermore, since the software filing information is the filing information of each software of the power equipment verified through software testing, a software comparison file can be generated based on the filing information and archived for acquisition when software comparison of the power equipment is required.

[0114] Step S230: Generate a comparison file ciphertext according to the types and models of all software in the power equipment.

[0115] It is understandable that since the filing and comparison files of power equipment are important documents to ensure the safe and reliable operation of power equipment, the filing and comparison files of power equipment need to be encrypted and archived, so it is necessary to generate a ciphertext of the comparison file.

[0116] Step S240: Determine the registration number based on the comparison file ciphertext and the software registration information.

[0117] Step S250: configuring the registration number into the power equipment.

[0118] The hardware comparison method of the power equipment provided in this embodiment performs software function test on each software of the power equipment after the hardware of the power equipment passes the comparison test to obtain the software test results of each software. If the software test results of each software are qualified, the software filing information of the power equipment is obtained, and a comparison file ciphertext is generated according to the types and models of all software in the power equipment. Based on the comparison file ciphertext and the software filing information, a filing number is determined, and the filing number is configured into the power equipment, so that the power equipment can be filed before operation. When the power equipment is subjected to software comparison, the filed software comparison file can be obtained, thereby ensuring the safe and reliable operation of the power equipment.

[0119] In some embodiments of the present application, the process of generating a comparison file ciphertext according to the types and models of all software in the power equipment in step S220 is introduced. Figure 3 As shown, the process may include:

[0120] Step S310: Determine a first ciphertext according to the types and models of all software in the power equipment.

[0121] Step S320: Determine the second ciphertext according to the production unit, production time and batch number of the electric power equipment.

[0122] Step S330: Perform a logical operation or shift processing on the first target ciphertext segment in the first ciphertext to obtain a first processed ciphertext segment.

[0123] The first target ciphertext segment may be a ciphertext segment randomly selected from the first ciphertext, or may be a ciphertext segment specifically selected from the first ciphertext.

[0124] It should be noted that the logical operation or shift processing of the first target ciphertext segment is not performed directly on the first ciphertext, but the first target ciphertext segment is selected from the first ciphertext, the first target ciphertext segment is copied, and the logical operation or shift processing is performed on the copied first target ciphertext segment to obtain the first processed ciphertext segment.

[0125] Step S340: Perform a logical operation or a shift process on the second target ciphertext segment in the second ciphertext to obtain a second processed ciphertext segment.

[0126] The length of the second processed ciphertext segment is equal to the length of the first processed ciphertext segment. The second target ciphertext segment may be a ciphertext segment randomly selected from the second ciphertext, or may be a ciphertext segment specifically selected from the second ciphertext.

[0127] It should be noted that the logical operation or shift processing of the second target ciphertext segment is not performed directly on the second ciphertext, but the second target ciphertext segment is selected from the second ciphertext, the second target ciphertext segment is copied, and the logical operation or shift processing is performed on the copied second target ciphertext segment to obtain the second processed ciphertext segment.

[0128] Step S350: Convert the first ciphertext into a third ciphertext by replacing the first target ciphertext segment with the second processed ciphertext segment in the first ciphertext.

[0129] It can be understood that the first target ciphertext segment in the first ciphertext is replaced by the second processed ciphertext segment, so the first ciphertext is changed and converted into the third ciphertext.

[0130] Step S360: Convert the second ciphertext into a fourth ciphertext by replacing the second target ciphertext segment with the first processed ciphertext segment in the second ciphertext.

[0131] It can be understood that the second target ciphertext segment in the second ciphertext is replaced by the first processed ciphertext segment, so the second ciphertext is changed and converted into the fourth ciphertext.

[0132] Step S370: Aggregate the third ciphertext and the fourth ciphertext to generate a comparison file ciphertext.

[0133] Specifically, the process of aggregating the third ciphertext and the fourth ciphertext to generate the comparison file ciphertext may include:

[0134] S71. Construct an encryption type array according to each software type information in the third ciphertext.

[0135] It is understandable that, since the power equipment includes multiple software, an encryption type array corresponding to each software can be constructed according to the software type information of each hardware. Therefore, for one power equipment, an encryption type array with the same number of software can be constructed.

[0136] S72. Construct an encrypted model array according to each software model information in the third ciphertext.

[0137] It is understandable that, since the power equipment includes multiple software, an encryption model array corresponding to each software can be constructed for the software model information of the software. Therefore, for one power equipment, an encryption model array equal to the number of software can be constructed.

[0138] S73. Construct an encrypted power equipment attribute array according to the production unit information, production time information and batch number information in the fourth ciphertext.

[0139] S74. Calculate the prefix sum of each element in each encryption type array, and construct a first prefix sum array according to the prefix sums of each encryption type array.

[0140] S75. Calculate the prefix sum of each element in each encryption model array, and construct a second prefix sum array according to the prefix sum of each encryption model array.

[0141] S76. Obtain a target array by performing staggered addition on each element of the first prefix sum array and each element of the second prefix sum array.

[0142] S77, connecting and aggregating the encrypted power equipment attribute array and the target array to obtain a comparison file ciphertext.

[0143] In some embodiments of the present application, the software comparison system mentioned in the above embodiments is further introduced. In addition to the device slots, the software comparison system may also include a bracket and a host computer.

[0144] The device slot may include a first device slot, a second device slot, a third device slot and a fourth device slot, and the first device slot, the second device slot, the third device slot and the fourth device slot may be arranged on the bracket. The first device slot, the second device slot, the third device slot and the fourth device slot may be respectively connected to the host computer through their respective communication serial ports.

[0145] Among them, since the aluminum alloy panel is neat and generous, not easy to be stained, and easy to clean and maintain, the bracket can be made of aluminum alloy such as iron-aluminum alloy. The bracket can also be equipped with a Fuma wheel, which saves labor, has good load-bearing capacity, is strong and durable, and is convenient for moving and transporting the device. The prototype support on the bracket can be compatible with various specifications of power equipment, with auxiliary terminals, which are used to press the prototype into the equipment position. The software comparison system can only use one 220V mains power cord to reduce miscellaneous wires. The power supply voltage of the software comparison system adopts 220V mains power, and the maximum power consumption is 1000VA.

[0146] Specifically, the prototype of the power equipment can be electrically connected to the host computer through the communication serial port, so that the power equipment communicates with the host computer.

[0147] The designated communication signal on the power equipment can be connected to the USB hub through the auxiliary terminal on the prototype tray, through the USB to designated communication module, so as to communicate with the host computer through the serial port. The USB hub can expand one USB interface into multiple independently working USB interfaces, which can be directly connected to the computer host. The computer automatically recognizes and installs without the need for a driver. It can support USB2.0 ports, 480Mbps speed, and is backward compatible with the built-in current overload short-circuit protection device of the USB1.1 port.

[0148] The prototype of the power equipment can be pressed onto the equipment position by automatic crimping, without the need for additional fixing structures such as screws.

[0149] In some embodiments of the present application, the software comparison system mentioned in the above embodiments is further introduced, and the software comparison system may also include an electric power equipment installation mechanism.

[0150] Among them, the power equipment installation mechanism may include an electric push rod and a control module, the electric push rod can be installed on the bracket, the working voltage of the electric push rod can be 24V, the rated power of the electric push rod can be 20W, the electric push rod can be driven by a relay, and the crimping and unloading can be completed by the upper computer in a specified manner. The upper computer can be connected to the electric push rod through the control module, and the 485 signal of the drive board of the specific electric push rod can be connected to the USB hub via the USB to 485 communication module, so as to communicate with the upper computer through the serial port.

[0151] Specifically, the electric push rod can be used to push the electric device into the fourth device position through the control module.

[0152] It is understandable that the electric push rod has high operating stability and can be used in different occasions. The electric push rod converts the electric rotor and the torsion arm into a modular product, converts the straight motion of the electric rotor into a rotary motion, so that the speed of the electric rotor is distributed and high-precision rotary motion is completed. The electric push rod can be used in various simple or complex process flows as an execution machine to achieve remote control, centralized control or automatic control. For different use occasions, different combinations of electric push rods and motors, special function accessories, etc. have different functions and scopes of use. The use of electric push rods saves space and has no dependence on external conditions.

[0153] The control module may include a relay and a driving chip connected to the relay.

[0154] Wherein, the driving chip can adopt STM32F03 microprocessor.

[0155] Specifically, the signal input end of the control module is electrically connected to the control signal output end of the host computer, and the output end of the control module is electrically connected to the crimping control end and the unloading control end of the electric push rod accordingly.

[0156] In some embodiments of the present application, the electric power equipment installation mechanism mentioned in the above embodiments is further introduced. In addition to the electric push rod and the control module, the electric power equipment installation mechanism may also include an overcurrent protection module.

[0157] Specifically, the overcurrent protection module may include a current detection circuit and an overcurrent protection circuit.

[0158] The current detection circuit may be used to detect the current signal of the electric push rod and input the current signal into the overcurrent protection circuit.

[0159] The overcurrent protection circuit can be used to determine whether the current signal exceeds a preset current threshold, and if so, stop outputting current to the electric push rod.

[0160] Specifically, the overcurrent protection circuit can determine whether the current of the electric push rod is overcurrent. When the current is too large or a stall occurs, it can identify and protect the electric push rod and stop outputting current to the electric push rod. Therefore, the overcurrent protection circuit can protect the electric push rod from overcurrent and improve its safety.

[0161] More specifically, the electric push rod current can flow through the sampling resistor, then be amplified by the low-pass filter circuit and the operational amplifier, compared with the set threshold voltage of the reverse input terminal of the operational amplifier, and finally converted into a level signal and processed by the microcontroller to determine whether there is overcurrent.

[0162] Furthermore, the electric power equipment installation mechanism may also include a pressure gauge in place detection module.

[0163] The pressure meter position detection module may include a status light arranged on the side of each device position in the device position slot, and an upper electrical contact terminal arranged directly above each device position in the device position slot.

[0164] Specifically, when the prototype and the corresponding device position are installed in place, the prototype is powered on, the power-on contact end on the prototype is connected to the power supply end of the status light on the side of the prototype, and the status light is on. Automatically identify whether the device position is crimped. Each table position has a status light. When there is no prototype, the status light will go out and there will be no voltage output at the device position. After the prototype is crimped in place, the status light will be on, and the prototype on the device position can be powered on.
