具体实施方式 Detailed ways

[0022] 需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。 [0022] Incidentally, in the case of no conflict, embodiments and features of the embodiments of the present application can be combined with each other. 下面将参考附图并结合实施例来详细说明本发明。 Below with reference to accompanying drawings and embodiments of the present invention will be described in detail.

[0023]本发明实施例提供了一种保护定值输入设备,图1是根据本发明实施例的保护定值输入设备的结构图,如图1所示,该保护定值输入设备包括:接口电路11和存储芯片13,其中,接口电路11用于接收或发送保护定值数据;存储芯片13,与接口电路11连接,用于存储保护定值数据。 Example embodiments provide a method of protecting an input setting device [0023] In the present invention, FIG. 1 is a configuration diagram of an input protection setting apparatus of the embodiment of the present invention, shown in Figure 1, the guard value input device comprising: an interface circuit 11 and the memory chip 13, wherein the interface circuit 11 for sending or receiving data protection values; memory chip 13, the interface circuit 11 is connected, for storing protection setting data.

[0024]使用该保护定值输入设备,保护操作人员可以根据保护装置应用的场合和要求将保护定值数据通过接口电路11预先存储到存储芯片13中,在保护现场通过接口电路11建立保护定值输入设备与保护装置的数据连接,向保护装置自动输入所述保护定值,从而及时、 快速、准确地进行保护定值输入工作,完成电气设备的保护配置工作,提高工作效率的同时保证了保护参数的正确性。 [0024] The use of the protective setting input device, to protect the operator can occasion and claimed device applications will protect setting data via the interface circuit 11 previously stored in the storage chips 13, the protective field via the interface circuit 11 to establish the protection given value input device and a data protection device is connected to the protective value input to the automatic protection devices, such that timely and quickly and accurately protect the input value, and completed the work of electrical equipment protection configuration, to improve work efficiency while guaranteeing protection parameters are correct.

[0025] 接口电路11可以具体包括两个传输接口,其中,第一传输接口111,与存储芯片13 连接,用于接收保护定值数据并传输给存储芯片13;第二传输接口113,与存储芯片13连接, 用于从存储芯片13中读取保护定值数据并发送给保护装置。 [0025] The interface circuit 11 may include two specific transmission interface, wherein the first transmission interface 111 is connected to the memory chip 13, for receiving and transmitting protected data value to the memory chip 13; a second transmission interface 113, and storage chip 13 is connected, to read the data and send protection setting protection device 13 from the memory chip.

[0026]上述第一传输接口111和第二传输接口113可以分别独立设置,也可以集成设置。 [0026] The first transmission interface 111 and the second transmission interface 113 may be provided independently or can be integrated set. 在分别独立设置时,接收保护定值数据的数据通道与发送保护定值数据的数据通道互相隔离,可以分别使用不同种类的传输接口,例如,将USB接口作为第一传输接口111,将串口接口作为第二传输接口113,从而,通过USB接口与保护整定计算装置连接,用于下载保护定值数据文件,通过串口连接保护装置,用于发送对应的保护定值数据。 When set separately, receiving the data channel and the protection channel data transmission of the data protection setting value data isolated from each other, they may use different types of transmission interfaces, respectively, for example, a USB interface as the first transmission interface 111, the serial port as a second transmission interface 113, thereby setting calculation device is connected via USB protection, protection setting for downloading data files, through the serial port connection protection means, for transmitting a corresponding data protection settings. 上述数据接口可以根据保护整定计算装置和微机继电保护装置的数据接口进行设置,具体地,第一传输接口111和第二传输接口113可以灵活选择以下传输接口中的任一种:USB传输接口、串口传输接口、无线射频传输接口 It said data interface means and setting data calculating means of protection set according protected computer interface, in particular, the first transmission interface 111 and the second transmission interface 113 can transmit the flexibility to choose any of the following interfaces: USB transmission interface , serial transmission interface, a wireless radio transmission interface

[0028] 由于保护定值数据可能实际到电网的实际情况,为了防止数据的泄露,提高保护定值输入设备使用的可靠性和安全性,该保护定值输入设备还可以设置加密芯片21和解密芯片23。 [0028] Since the protective data may be the actual value to the actual situation of the grid, in order to prevent leakage of data, to improve reliability and safety equipment to protect the value of the input, the setting input protection device 21 may also set the encryption and decryption chips chip 23.

[0029] 图2是根据本发明实施例的保护定值输入设备的另一种结构图,如图所示,该保护定值输入设备设置了加密芯片21和解密芯片23。 [0029] FIG. 2 is a block diagram of a further protection setting input device of the present embodiment of the invention, as shown, the guard value input device 21 is provided encryption and decryption chips 23 chips. 其中,加密芯片21,设置在存储芯片13和第一传输接口111之间,用于对接收到的保护定值数据进行硬件加密。 Wherein the encryption chip 21, is provided between the memory chips 13 and the first transmission interface 111, for protecting the value of the received data encryption hardware. 解密芯片23,设置在存储芯片13和第二传输接口113之间,用于对向保护装置发送的保护定值数据进行硬件解密。 Decryption chip 23, 13 is provided between the memory chip and the second transmission interface 113, for protection setting data transmitted to the decryption hardware protection device. 从而存储芯片13中的数据经过了加密,提高了数据的安全性。 13 so that the data in the memory chip is encrypted to improve the security of the data. 防止除保护装置之外的设备或计算机进行读取。 In addition to preventing device or computer protection apparatus for reading.

[0030] 上述存储芯片13可以优选使用闪存存储芯片I3,利用NAND Flash芯片。 [0030] The memory chip 13 can be preferably used a flash memory chip I3, NAND Flash chips use.

[0031] 在使用本实施例的保护定值输入设备时,可以将一份保护定值单的格式及其内容存储在保护定值输入设备,该保护定值数据可以根据保护类型保存为多个文件,例如变压器差动保护定值文件、变压器后备保护定值文件,母联保护定值文件、l〇KV线路保护定值文件,一个保护定值输入设备可以保存一种定值文件,从而制成分别不同的保护定值设备。 [0031] When using this embodiment the protective value input device, can be protected by a single value format and stored in the protected content setting input device, the protective setting a plurality of data can be stored according to the type of protection file, for example transformer differential protection settings files transformer backup protection setting file, mother of protection settings files l〇KV line protection setting file, a value input device may be protected by holding one value document, thereby preparing to respectively different guard setting device. 一个保护定值输入设备也可以存储有多个定值文件,在使用时根据指令读取对应的数据。 A protection setting input device may store a plurality of settings files, reads the corresponding data according to the instruction in use.
