变电站智能门禁系统 Substation Intelligent Access Control System

技术领域 FIELD

[0001] 本实用新型涉及变电站智能门禁系统,尤其涉及集控中心加无人值班变电站模式下的变电站智能门禁系统。 [0001] The present invention relates to a smart entry system substation, in particular in the smart entry system substation control center plus relates unattended substation mode.

背景技术 Background technique

[0002] 随着电力自动化技术的发展,电力系统内的变电站基本实现了无人值班,变电站的运行维护采用了集控中心加无人值班的模式。 [0002] With the power of automation technology, power system substation in the basic realization of the unmanned substation operation and maintenance mode uses a centralized control center plus unattended. 一个集控中心负责一个区域内多个变电站的日常巡视、操作和许可外来人员施工等工作,进入变电站必须到集控中心取相应变电站的系列钥匙。 A centralized control center responsible for daily inspections, operation and licensing of foreign workers in the construction work more than one area of ​​the substation, the substation must be entered into the control center to take the appropriate series of key substations. 变电站分布往往比较分散,其大门、控制室和开关制室等的门锁通常采用机械锁,钥匙众多使用和管理困难。 Substation distribution tends to be spread, which locks the door, switching system control room and rooms and other commonly used mechanical locks, and the use of many key management difficulties. 无人值班变电站的开门问题已成为影响下作效率的一个重要方面,当有紧急操作或事故处理时,运行人员需要往返于集控中心与变电站之间取还钥匙;当外来工作人员需要进入变电站时,同样必须往返于集控中心与变电站之间取还钥匙。 Open question unmanned substation has become an important aspect affecting the efficiency of testimony, when there is an emergency or incident handling operations, operators need to travel between the control center and substation also take the keys; when foreign workers need to get into the substation , the same key must also be taken to and from between the control center and substations. 国家电网公司实行电网“大检修”模式后,一个集控中心负责地级市内的220kV变电站的运维工作,地域跨度可达百公里,因为钥匙的问题占用更多的时间。 After the implementation of the national grid company Grid "Overhaul" mode, operation and maintenance work a centralized control center in charge of prefecture-level city of 220kV substation, geographical span of up to 100 km because of key issues take more time.

[0003]目前电力系统自动化能对变电站任何设备的实时工况和动作情况进行记录和上传,但对于变电站及控制室大门开启和人员进出情况没有记录上传。 [0003] the current power system automation can record and upload real-time operating mode of any device substations and action cases, but for the substation and control room personnel entering and leaving the door open and without a record uploaded. 对于变电站工作人员的巡视周期管理和外来人员进入管理只能通过问询方式,不利于加强变电的安全运维管理。 For inspection cycle management and staff of foreign workers into the substation management only by way of inquiry, it is not conducive to strengthening the security operation and maintenance of the substation. 因此,利用目前变电站里现有的网络资源,设计出一套智能门禁管理系统非常必要。 Therefore, the use of the current substation in the existing network resources, design a set of intelligent access control system is necessary.

[0027] 集控中心的变电运维人员进行变电站日常巡视或操作时,只需带I张RFID卡就可以进入管辖区域的任何一座变电站;到变电站时,变电运维人员刷卡正确后输入个人识别密码,门禁控制器与储存器内信息进行比对,正确后开放相应门禁,记录信息上传至门禁服务器中;门禁服务器实时显示某变电站何种人员以何处方式值得时间打开门禁;在一个变电站可将RFID卡设置成“一站通”,在本站任何一处读卡器读卡和输入个人识别密码后,可在短时内开放本站所有门禁。 When the [0027] current variable control center operation and maintenance personnel perform routine inspections or substation operation, only sheets with RFID card I can enter any jurisdiction of a substation; when the substation, the substation maintenance personnel correctly enter the card personal identification code, the access control and storage of information for comparison, the corresponding access opening is correct, the recording information is uploaded to the server access; access server real-time display of a transformer substation in which the art is worth the time where the open access mode; in a substation RFID cards can be set to "one-stop", all access any site in a reader and a card reader enter a personal identification code, the site can be opened in a short time. 一张RFID卡对应多个班次的变电运维人员,通过个人识别密码进行区别;变电运维人员工作结束时,关闭控制室门、控制楼门和变电站大门,门禁将自动上锁,并将关门信息上传门禁服务器;当变电运维人员中途接到指令需要进入其他变电站时,无需重返集控中心取钥匙,按上述步骤进入相应变电站。 An RFID card substation operation and maintenance personnel correspond to multiple shifts, distinguished by a personal identification code; the end of the substation operation and maintenance personnel work, turn off the control room door, substation control building door and door, access control is automatically locked, and closing the access server information is uploaded; when substation maintenance personnel require access to other intermediate instruction to the substation, without returning to take the key control center, the steps described above into the respective substation.

[0028] 非变电运维人员进入变电站工作时,必须到集控中心取钥匙进入变电站工作,工作结束后到集控中心还钥匙;采用变电站智能门禁时,进站人员到达变电站时向集控中心电话申请进站,集控中心值班人员在门禁服务器上选择相应的变电站产生跳码,工作人员输入跳码进入变电站;当集控中心无值班人员,可由值班长在其所持的值班公用手机的跳码程序选择相应的变电站产生跳码,进站人员输入跳码进入变电站;当紧急情况下集控中心人员在门禁服务器上操作远程直接打开变电站门锁,相关进站人员进入变电站进行工作 [0028] Non-variable substation maintenance personnel enters the work must be taken to the keyless entry control center substation work, after work to further the key control center; with intelligent access substation, the substation to stop when the person reaches the centralized control Center stop telephone applications, duty control center to select the appropriate substation to skip the access code on the server, the staff enters the input jump code substation; if no duty control center, which may be held in a long duty duty public phone hopping code generating program selects the appropriate substation jump code, stop code hopping personnel enter into the substation; if direct control center to remotely open the door substation, the substation personnel to enter relevant stop access server operating on an emergency work

[0029] 如图4所示,门禁单元的工作步骤如下: [0029] As shown in FIG working steps, the access control unit 4 as follows:

[0030] a)、门禁控制器判断是否有外大门门禁终端送来的刷卡及密码信息,如有进入步骤b);没有刷卡及密码信息,返回步骤a); [0030] a), the controller determines whether the external access door access terminal and password information sent from the card, if proceeds to step B); password and credit card information is not, returns to step A);

[0031] b)、如果是刷卡信息,则进入c);如果是密码输入信息则进入; [0031] b), if the credit card information, the process proceeds C); if the password input information proceeds;

[0032] c)、门禁控制器进行卡合法性检查,通过读取用户数据库,查看此卡号是否存在和有效,如果存在并有效,进入步骤d);如卡号不存在或者无效卡,语音提示后返回步骤a); [0032] c), the access controller checks the validity of the card by reading a user database to see if this card is present and valid, and if there is valid, proceeds to step d); after the card as the card is not present or is invalid, the voice prompts returning to step A);

[0033] d)、语音提示输入个人识别密码,等待密码输入; [0033] d), the voice prompts for personal identification code, password input wait;

[0034] e)、控制器将输入的个人识别密码与储存器的数据进行比较,若密码无效,则返回步骤d);密码正确,则进入步骤i); [0034] e), the password and personal identification data storage controller compares the input, if the password is invalid, return to step d); password is correct, the process proceeds to step I);

[0035] f)、门禁服务器是否下发跳码,如下发,则进入步骤g);否则,进入步骤h); [0035] f), whether to send the access server code hopping, as made, the process proceeds to step G); otherwise, step H);

[0036] g)、门禁控制器将输入的密码与服务器下发的跳码进行比较和时间判断,有效则进入步骤i);无效则经语音提示后返回步骤a); [0036] g), delivered by the access control server hop password input time code comparison and determination, the process proceeds to step valid I); voice prompt is invalid after returning to step A);

[0037] h)、控制器认为该输入密码为手机产生的跳码,调用跳码解密程序进行解密,有效则进入步骤i);无效则经语音提示后返回步骤a); [0037] h), the controller that the hopping code password generated phone call hopping code to decrypt the decryption program, the process proceeds to step effective I); voice prompt is invalid after returning to step A);

[0038] i)、语音提示密码输入正确,根据预设的密码控制开门的范围打开三道门禁或第一道门禁,记录此次刷卡、密码输入方式及时间等信息,并向服务器发送此次开门情况信息,结束本次流程。 [0038] i), the voice prompts to enter the correct password, the control range of the door or access opening of the first three channel access according to a preset password, the recording card, password input mode and time information, and sends the server open the information, the end of this process. 如果预设的密码控制范围为第一道门禁,则后续门禁按上述步骤重复进行。 If the preset password for the control of a first channel access, the subsequent access procedure is repeated as described above.

[0039] 本实用新型中门禁控制器在每次刷卡和输入密码时都有语音提示,在使用RFID卡加个人识别密码的电子钥匙时,连续5次输入个人识别密码错误将返回等待状态,需要重新刷卡;使用跳码时,连续5次输入密码错误需要重新申请跳码。 [0039] In the present invention, the controller has access voice prompts at each card and a password, when the RFID card with a personal identification code using an electronic key, 5 times a personal identification password input wait state error is returned, it is necessary re card; use code hopping, enter the wrong password five consecutive times need to reapply code hopping.
