As preferred embodiment, when infrared induction module has sensed operator close to then second source line, the Three power supply lines out-put supply immediately is powered to wireless communication module and radio frequency identification module, when infrared induction module senses behaviour It is left as personnel, second source line, third power supply wire delay several seconds cut off the power again.Specific delay time can be 10 Second, it can be 20 seconds, be also possible to other values, determined by programmer in programming.
Preferably, wireless communication module selects wireless network card.When infrared induction module has sensed operator close to simultaneously After starting wireless communication module, protective relaying device accesses WLAN, and real-time by WLAN probe request The MAC Address of the portable terminal device of grasping manipulation personnel, and the MAC Address grabbed in real time is sent to data processing mould Block, data processing module is with calling the MAC Address of the ustomer premises access equipment prestored in data memory module and the MAC of implementation crawl Location is compared, the identity of confirmation operation personnel.Wherein, the probe request is that 802.11 WLAN of IEEE is general Standard is defined.
Preferably, radio frequency identification module include built-in antenna and RFID reader and operator carry it is suitable In the electronic tag connecting with RFID reader signal, herein, which is that setting is portable in operator ID card coding in ID card.After infrared induction module has sensed that operator approaches and starts radio frequency identification module, Mutually incude between RFID reader and electronic tag, which reads compiles as the ID card of electronic tag Code, and ID card coding is sent to data processing module, data processing module calls the behaviour prestored in data memory module The ID card coding for making personnel is compared with the ID card coding currently recognized, the identity of confirmation operation personnel.
Preferably, dsp chip or fpga chip can be selected in data processing module, realize that comparing MAC Address and ID card compiles The function of code, while realizing the control to module information interaction.
Preferably, SD storage card can be selected in data memory module, since SD storage card has small in size, data transmission bauds Fastly, hot-swappable good characteristic, so configuring the MAC that SD storage card is used to store ustomer premises access equipment in protective relaying device The data such as address, the ID card coding of operator, operator's operating right and operation interface corresponding with operating right It has great advantages, and can facilitate when operator changes or operating right changes and carry out data update.
Preferably, display module selects liquid crystal display, more information can be shown, and color is relatively abundanter, depending on Feel that impression is relatively good.
Corresponding with above system, the present invention provides a kind of method of protective relaying device identification user identity, such as Fig. 2 It is shown, method includes the following steps:
Step 1, whether the infrared induction module configured by protective relaying device, induction have operator close;
Step 2, when having sensed that operator is close, wireless communication module and penetrate that starting protective relaying device configures Frequency identification module accesses WLAN, while carrying out radio frequency identification;
Step 3, protective relaying device sends the real-time grasping manipulation personnel of probe request by WLAN and takes with oneself The MAC Address of the ustomer premises access equipment of band, while being identified by ID card of the radio frequency identification module to operator, obtain behaviour Make the ID card coding of personnel;
Step 4, protective relaying device compares the MAC Address prestored in the MAC Address and protective relaying device grabbed, together When compare the ID card coding of radio frequency identification and encoded with the ID card that prestores in protective relaying device, the body of confirmation operation personnel Part;
Step 5, protective relaying device reads the operating right with operator's identities match of confirmation, transfers relay protection Device configuration with the matched operation interface of the operating right, by the operation interface by display module be shown to operator with Carry out human-computer interaction.
Specifically, only when MAC Address matches, correct and ID card codes match is correct, the body of ability confirmation operation personnel Part and transfer operation interface corresponding with its operating right and shown.
As a preferred embodiment, the present invention may also include fingerprint identification module, for further confirming that operator's Identity.Existing fingerprint identification module can be selected in fingerprint identification module, and is installed in protective relaying device surface.Fingerprint is known Other module is connect with data processing module, and the fingerprint of the operator with operating right is stored in advance in protective relaying device Information, it is inconsistent to occur during confirmation operation personnel identity in protective relaying device comparison MAC Address and ID card coding The case where when, i.e., MAC Address matching but ID card coding mismatch or ID card codes match but MAC Address mismatch, number Prompting message is sent to display module according to processing module, is reminded operator to carry out fingerprint recognition, is further confirmed that operator Identity improves identity validation accuracy.
As a preferred embodiment, the present invention may also include face recognition module, for further confirming that operator's body Part.Face recognition module includes existing recognition of face program and the setting of protective relaying device front end preset in data processing module High-definition camera.Go out during protective relaying device compares MAC Address and ID card coding with confirmation operation personnel identity When showing inconsistent situation, i.e., MAC Address matches but ID card encodes mismatch or ID card codes match but MAC Address It mismatches, data processing module sends prompting message to display module, and operator is reminded to see that, to high-definition camera, shooting is current The face information of operator carries out recognition of face, further confirms that operator's identity, improves identity validation accuracy.
The present invention by infrared induction module sense operator after, start wireless communication module and radio frequency and know Other module accesses WLAN, and carries out the identification of operator's ID card;Then protective relaying device is by sending detection The MAC Address of equipment entrained by claim frame grasping manipulation personnel, while operator's ID card is identified by radio frequency identification module Coding, and the body that the MAC Address prestored in the MAC Address of crawl and protective relaying device is compared, while will recognized Part card coding is compared with the ID card coding prestored in protective relaying device, completes the confirmation to operator's identity;? After the identity for determining operator, by the operating right with operator's identities match prestored in protective relaying device, it is Determine that the operator of identity provides corresponding operation interface, and shown by display device, to facilitate operation personnel into Row human-computer interaction.The method of the present invention improves while quick determining operator's identity to operator's identification Accuracy rate, and it is difficult for the work that the mode that the operator of different rights provides different operation interface reduces operator Degree, improves work efficiency.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
