Description

一种用于通信设备群的低压直流电源组及其备份方法 Group and low voltage DC power backup method for a communication apparatus group

技术领域 FIELD

[0001] 本发明属于通信设备技术领域,特别是涉及一种用于通信设备群的低压直流电源组及其备份方法。 [0001] The present invention belongs to the technical field of communications devices, and more particularly to low voltage DC power group and its backup method for a communication apparatus group.

背景技术 Background technique

[0002] 随着信息技术的迅猛发展,电信、能源、国防、政企办公以及广大公众对通信的需求和要求越来越高,提供信息传递服务的通信设备的可靠性、安全性和经济性既是实施高效优质通信的关键,也是市场准入的重要门槛之一。 The reliability of communication equipment [0002] With the rapid development of information technology, telecommunications, energy, defense, government and enterprise communications office and the general public demand and increasingly high demand, provide messaging services, security and economy the key to effective implementation of both the quality of communication, but also one of the important market access barriers. 目前,以机架插卡式为代表的通信设备普遍应用于通信、工控领域,安装于电信运营商、行业专网用户、工矿企业的通信机房,以及智能楼宇、豪华住宅等场所的信息机房,可向用户提供电话、视频、网络、专用数据、控制数据等业务服务。 At present, rack card type, represented by communications equipment widely used in telecommunications, industrial areas, the installation room information on places of telecom operators, industry professionals network users, industrial and mining enterprises in the communications room, as well as intelligent buildings, luxury residential, can provide telephone, video, Internet, to user specific data, control data, and other business services. 机架插卡式通信设备是信息网络通信的关键节点,发挥着网络通信枢纽与信号汇聚的桥樑与纽带作用。 Rack card communication device is a communication network node information of the key, it plays the role of a network bridge and link the signal convergence communications hub. 该通信设备具有容量大、功能全等特点,为保证设备运行中的可靠性和安全性,其供电电源一般都采用1:1或1: N备份方式设置。 The communication device has a large capacity, functional characteristics congruent, in order to ensure reliability and safety of the equipment operation, the power supply is generally 1: 1 or 1: N backup set. 现有公知的通信设备电源单元备份设置有以下几种:一是按电源板备份切换方式分类:有热备份、冷备份;二是按电源板对设备的供电方式分类,有分布式供电备份、集中式供电备份;三是按电源板的安装方式分类,有机框外单板电源与机框内电源单元互为备份、机框内电源板1+1备份等。 Conventionally known communication device is provided with a backup power supply unit the following: First classified by switched mode power supply backup plate: a hot backup, cold backup; Second embodiment according to the power supply board device classification, distributed backup power supply, centralized power backup; third classified by mounting the power board, power board and the outer frame organic machine frame mutual backup power supply unit, power board subrack 1 + 1 backup. 这些备份设置方式虽然均能实现通信设备中两个以上电源单元互为备份的功能,但不足之处是必须指定一个单独的电源单元作为备份模块,如大功率电源模块、单板电源转换模块或与主用电源板相同的电源板等,这样不仅会造成备份电源单元损坏而使通信系统运行出现中断的风险,而且这种电源备份设置均存在造价高和能耗大的缺点。 Although these backup setting mode communication device can achieve more than two power supply units to back up each other function, but the downside is that a separate power supply must be specified as a backup module means, such as a power supply module, the power converter module or board the main power supply board the same board power supply, not only can cause the risk of damage to the backup power supply unit interrupts communication system operation occurs, and this backup power settings are high cost and large power consumption drawback.

[0003] 中国专利申请200710181475.5公开了“一种单板电源备份方法及单板电源备份系统”,该方案提出先通过母线引入电压给单板;再通过单板上的DC/DC将引入的电压转换为所需的低压,同时设置一个备份电源,将其输出引入各单板,在单板电源正常工作时,将备份电源回路断开,当单板电源失效时,将备份电源回路置为闭路。 [0003] Chinese Patent Application No. 200710181475.5 discloses "a method and board power backup board power backup system", the voltage is introduced to the first solution proposed by the bus board; then the board by introducing a DC DC / voltage is converted to the desired low pressure, and a backup power supply is provided, which is introduced into the output of each board, when the board power supply is normal, the backup power supply circuit is disconnected, when the board power failure, the backup power supply circuit is set to the closed . 该方案虽然可使备份电源的功率下降、制造成本减小,但还存在明显不足:一是采用母线引入供电电源给单板的供电方式,因为电源输入端连接上位电源,如果输入母线连接多台上位供电电源,而输入电源又采用母线方式,当输入母线因误操作而引起短路、正负接反、电源碰地时,将会对通信设备造成大面积影响,引起并联在母线上的所有单板和供电模块,特别是多台上位电源设备工作异常,损坏电源模块或上位电源设备;二是即使电源系统输入输出均有保护电路,也会因母线短路而造成与母线上所有电源板和关联的设备系统瞬间断电而运行瘫痪,影响系统供电的可靠性;三是需要有一台单板电源作为备份,既增加了设备型号、种类与备份成本,给生产、维修和管理增加难度,又使系统增加了新的故障隐患。 Although this scheme allows the backup power supply is decreased, the manufacturing cost is reduced, but there are obvious drawbacks: First, using the power supply bus bar is introduced to the board power supply, since the power supply input terminal connected to an upper power supply, if a plurality of input bus connection host power supply, the input power and bus use mode, when the positive and negative reversed, when the power supply touch the ground, will cause large effect on the communication device, causing all single parallel bus on the input bus short circuit caused by malfunction, board and power supply module, in particular a multi-bit stage power supply device is not working, an upper module or damage the power supply device; second power supply system even when the input and output protection circuits are also all due to short-circuit in the bus plate and power associated with the bus the power outages and equipment systems running paralysis, affect the system reliability of supply; the third is the need for a single board as a backup power source, not only increasing the device model, type and backup costs, to production, maintenance and management more difficult, and the the system adds a new hidden faults.

[0004] 中国专利申请03128402.7公开了“一种二次电源备份方法及装置”,该方案提出将备电源模块设置在其中一功能模块上,使该备电源模块的输出电压分别与每一功能模块的主电源模块的输出电压通过隔离降压后向相应的功能模块同时供电,调节备电源模块输出使其电压低于所在功能模块主电源模块正常工作时的输出电压,以保证在功能模块的主电源模块正常工作时备电源模块输出小电流,而在功能模块的主电源失效时自动输出大电流。 [0004] Chinese Patent Application No. 03128402.7 discloses "a method and a secondary power supply backup means", the program proposed to the standby power module is provided in which a functional block, the output voltage of the backup power module and each of the functional modules are output voltage of the main power supply through the module isolation step-down power to the respective functional modules simultaneously, so that the output power is adjusted standby voltage lower than the output voltage of the master power supply module where the function module is working properly, in order to ensure that the main functional modules the power modules work properly when the output power is small current, a large current is output automatically when the main power failure function module. 该方案虽然可解决现有通信设备备份电源存在设计复杂、制造成本高等问题,但还存在明显不足:一是采用在功能模块上增加备用模块的备份方式,不仅设计与控制更加复杂,增加了通信设备的故障风险,而且还增加了通信设备系统的成本;二是将输入母线并联,同样会出现上述的中国专利申请200710181475.5方案存在的可靠性隐患;三是为主备倒换设置了判决电路,如判决电路故障,将无法判决或误判主用板的实际工作态,此时将存在主备电源模块同时输出大电流的可能,从而导致低压母线电流过大而使末端供电产生压降,也存在当主用板失效后,因误判而备用板没有及时启用的可能,导致影响系统正常运行,同时备用板本身出现故障而持续输出大电流时,会缩短备用板的使用寿命。 Although this solution solves the conventional communication device backup power present design complexity, manufacturing cost is high, but there are obvious drawbacks: First, by increasing backup spare module in the function module, only more complicated design and control, increased communication risk of failure of the device, but also increases the cost of the communication device of the system; second input bus in parallel, the same reliability risks Chinese patent application 200710181475.5 above-described embodiment will be present; Third-based switchover decision circuit is provided, such as fault judgment circuit, judgment or not the actual operating state of the master misjudgment plate, in which case there will likely the power modules simultaneously output a large current, resulting in the low voltage bus terminal supply current is too large a pressure drop, there when the active board fails, the standby board due to misjudgment may not timely enabled, resulting affect the normal operation, the standby board itself fails while continuously output a large current can shorten the life of the backup plate.

[0005] 如何克服现有技术的不足已成为当今通信设备技术领域中亟待解决的重大难题。 [0005] how to overcome the deficiencies of the prior art has become a major problem in today's field of communication technology devices to be solved.

[0010] 首先,计算通信设备群的总体功耗,计算配置电源板的数量与电功率,使其满足以下算式: [0010] First, calculate the overall power consumption of the communication device group, the number of calculated electric power source arranged plate so as to satisfy the following equation:

2XW3 > (W1-W2) > W3 2XW3> (W1-W2)> W3

[0011] 上式中,以通信设备群为单位,Wl为该通信设备群所有电源板的最大输出功率之和,W2为该通信设备群所有通信设备的功耗之和,W3为该通信设备群中输出功率最大的电源板输出功率; [0011] In the above formula, the group as a unit to a communication device, the maximum output power for the Wl group of communication devices and all power plate, W2 group of communication devices for all communication devices and the power consumption, W3 for the communication device group output power maximum output power of the power board;

[0012] 其次,将每块电源板的输出电功率的导线与隔离二极管正极连接,隔离二极管负极经均流电路与低压直流电源母线连接; [0012] Next, the wires of each of the output electric power of the power board isolation diode connected to the positive, the negative electrode via the current-blocking diode circuit connected to low voltage DC power bus;

[0013] 再次,采用均流输出控制法使每块电源板实现均流输出,使所有输出的低压电源功率在低压直流电源母线上叠加,共同承载通信设备群的业务负载。 [0013] Again, using the current-control method that the output of each power board achieve current output, low voltage power supply so that all output power is superimposed on the low voltage DC power supply bus, the common carrier communication device group traffic load.

[0014] 本发明的低压直流电源组备份方法的进一步优选方案为:本发明所述的隔离二极管为肖特基二极管,反向隔离耐压为不小于DC60V ;本发明所述的均流输出控制法为下垂均流法。 [0014] In a further preferred embodiment a low voltage DC power pack backup method of the present invention is: according to the present invention is isolated diode is a Schottky diode, a reverse isolation voltage is not less than DC60V; current-output control according to the present invention law droop current sharing method.

[0015] 本发明的低压直流电源组及其备份方法的可靠性原理:本发明输入电源为DC-48V,采用每台通信设备独立供电的方式,由电源线路单独输入每台通信设备的电源板,再通过保护电路进入DC/DC模块。 [0015] Reliability and principles set low voltage DC power backup method of the invention: The present invention is the input power supply DC-48V, each communication device uses an independent power supply manner, the input power from the power line communication apparatus for each individual board , then enters through the protection circuit DC / DC module. 每台通信设备的DC-48V电源母线并不相连,即使某台通信设备的输入电源出现故障,如短路、碰地或断线等均不影响通信设备群中的其它各通信设备输入电源,保证了通信设备群整体运行的可靠性,具体说明如下: DC-48V power bus of each communication device is not connected, even if the input of a power station communication apparatus fails, such as short circuit, collision or disconnection of each communication device not affect other communication device group of input power to ensure the reliability of the overall operation of the communication device group, as defined below:

[0016] 第一,本发明在供电电源消失时的可靠性。 [0016] First, the present invention is the reliability of the power supply disappears. 供电电源消失通常表现在某台通信设备没有接收到DC-48V输入供电电源,导致该通信设备的电源板停止工作而不输出低压直流至低压直流母线。 Power supply disappears usually manifested in a communication station device does not receive the input DC-48V power supply, causing the power board communication device is stopped without outputting a low voltage DC to low voltage DC bus. 因此,本发明将单台低压直流电源母线与通信设备群的低压直流电源母线并联,故该台通信设备的低压直流电源由通信设备群中的富余电功率提供,使该台通信设备的低压直流电源继续为该台通信设备的所有业务处理板供电,维持通信设备的业务不中断,为排除该通信设备的故障带来了极大的方便。 Accordingly, the present invention is the low voltage DC power bus single low voltage DC power bus communication device group in parallel, so that surplus electrical power low-voltage DC source communication device group of the sets of communication device is provided, so that the station communication device of low-voltage DC power supply continue all LPU power supply station for communications equipment, communications equipment to maintain uninterrupted services to troubleshoot the communication device brought great convenience.

[0017] 第二,本发明在供电线路短路时的可靠性。 [0017] Second, the present invention is the reliability of the short circuit in the power supply line. 通信设备的供电线路短路时常会发生正负极短路或与其他电压源短路的故障,造成因供电线路短路而引起的电源板、上位供电电源的损坏,即使设置保护电路,也会使电源板工作异常。 Short circuit of the power supply communication device often positive and negative short circuit or other voltage source with a short-circuit malfunction, damage due to power supply board short circuit caused, the upper power supply, even if the protection circuit, the power supply board will also work abnormal. 为解决这一问题,本发明采取分布式供电,每台通信设备的DC-48V输入互不相连,即某条供电线路短路不会对其他通信设备造成影响,只是该台设备的电源板没有低压直流电源输出而已,即使该台设备的电源板没有输出低压直流电源到通信设备群的低压直流母线,但由于通信设备群的所有设备的低压直流电源母线是并联的,所以仍然可为其提供低压直流电源,而不影响该台通信设备及通信设备群中的其他通信设备业务系统的正常运行,为排除该通信设备的故障带来了极大的方便。 To solve this problem, the present invention takes the distributed power supply, each communication device DC-48V input unconnected, i.e. a short circuit power strip does not affect the other communication device, only the power board is not a low pressure device DC power output only, the device even if the power board is not low voltage output low voltage DC power to the DC bus communication device group, but the low voltage DC power bus for all devices of the group of communication devices are connected in parallel, it can still provide a low pressure DC power, without affecting the normal operation of other communication devices of the service station system of the communication device and communication device in the group, to troubleshoot the communication device has brought great convenience.

[0018] 第三,本发明的低压直流电源母线并联的可靠性。 [0018] Third, the present invention is a low voltage DC power bus in parallel with reliability. 本发明的低压直流电源母线将通信设备群中的所有电源板输出并联在一起,组成该群中所有通信设备供电的电源组,本发明的低压直流电源母线的连接范围仅限在其所在的通信设备群中,不与外部第三方的供电设备直接连接,所以当低压直流电源母线短路时,不会出现现有技术中因输入电源母线并联而造成第三方设备如上位电源设备故障发生。 A low voltage DC power bus of the present invention will be output in parallel all the power board in the group of communication devices together to form the group of all the power supply communication device group connected to low voltage DC power bus scope of the present invention in which it is in communication only group of devices, a third party is not directly connected to an external power supply apparatus, when the low voltage DC power bus short circuit, the prior art does not occur due to the power bus input parallel bits as caused by third-party equipment power supply failure. 同时,对通信设备群中的各通信设备的业务板卡接收低压直流电源母线供电,在每块业务处理板的电源进线处设置过流过压保护电路,即使低压直流电源母线短路,也不会损坏业务处理板,当故障恢复时即可正常运行。 Meanwhile, the receiving low voltage DC power supply bus business cards each communication apparatus in the group of communication devices, over-current protection circuit is provided in each power line at the LPU, even if the low voltage DC power bus short circuit, not damage the LPU, when the recovery to normal operation. 由于本发明的低压直流电源母线并联不涉及外部第三方,即使出现故障其影响范围小,且在可控范围内,从而大大提高了本发明的可靠性。 Since the low voltage DC power bus in parallel with the present invention does not relate to external third-party, even if the failure of its small sphere of influence, and under control, thus greatly improving the reliability of the present invention.

[0019] 本发明与现有技术相比,其显著优点是:第一,本发明采用分布式电源输入和集中输出低压直流电源给负载供电方式,既发挥了低压直流电源组自身储备的富余电功率为电源组备份供电的优势,又避免了由于某个输入单元故障而造成通信设备群整体发生供电故障,这样可大大提高通信设备的可靠性和安全性;第二,本发明的低压直流电源组割除了现有技术中所述的电源备份单元设置,没有主备电源板之分,电源板设置数量更加合理,且物尽其用,使通信设备的制造成本显著降低,运行功耗降低、运行成本明显减小,以及产品的性价比高、经济性好;第三,本发明的备份方法实施简便可靠,生产、检验和管理容易掌控;第四,采用本发明的备份方法,即使某个输入电源消失,通信设备群中的所有单体通信设备运行均不受影响,给更换出现单体故 [0019] Compared with the prior art, which are significant advantages: first, the present invention is distributed and centralized power input output low voltage DC power supply to the load mode, only played a low voltage DC power surplus electric power reserve group itself back-up power supply for the advantage of the group, but also avoids an input unit failure caused by power failure occurs the entire group of communication devices, which can greatly improve the reliability and security of the communication device; a second, low voltage DC power pack of the present invention cut off the power backup unit is arranged according to the prior art, no sub-main power board, the power board is provided more reasonable number, and the best use of the manufacturing cost of the communication device is significantly reduced, to reduce operating power, the operation costs are significantly reduced, and high product cost, good economy; third, backup method is simple, reliable embodiment of the present invention, production, testing and management easy to control; fourth, the present invention backup method, even if a power supply input disappearance of all monomers communication device communication device operating in a group are affected, so the monomers to replace a 的电源板带来了极大的方便。 The power board has brought great convenience. 本发明适用于对各种通信设备群低压直流电源组的备份。 The present invention is applicable to various communication devices to back up the group of low voltage DC power pack. 本发明与现有技术性价比较详见如下表I。 The present invention is more effective with the prior art as indicated below in Table I.

[0030] 上式中:以通信设备群为单位,Wl为该通信设备群所有电源板的最大输出功率之和,W2为该通信设备群所有通信设备的功耗之和,W3为该通信设备群中输出功率最大的电源板输出功率。 [0030] In the above formula: A group of communication devices as a unit, the maximum output power for the Wl group of communication devices and all power plate, W2 group of communication devices for all communication devices and the power consumption, W3 for the communication device group output power maximum output power of the power supply board. 该通信设备群中每台通信设备的单块电源板的设计输出功率是该台通信设备满配时负载总功耗的1.25倍以上,或该台通信设备的最高满配负载是电源板输出功率的80%,由于低压直流电源母线的建立使每台通信设备富余的电源功率叠加在一起,形成了通信设备群的电源富余输出功率远远大于单板的输出功率,可作为备用电源供通信设备群使用,在配置通信设备群的单体通信设备的电源板时,只需计算出所有负载的总功耗,配置相应数量的电源板即可,这样将大大节省电源板的配置数量,降低电源板的故障率,提高通信设备的可靠性,降低机房供电系统的负载,达到节约能源、节省设备成本的目的。 The group communication apparatus monolithic design output power of each power board communication device is not less than 1.25 times the total power consumption when the load of the station with full communication device, or up to the full-load station with a communication device is the power output plate 80%, due to the establishment of low voltage DC power bus so that each communication device power surplus power added together, formation of surplus power output power far greater than the group of communication devices output board, available as a backup power supply for a communication device group used, when the power supply board arranged group of communication devices monomer communication device only needs to calculate the total power consumption of all loads, arranged corresponding to the number of power supply board, which will greatly reduce the number of configurations of the power supply board, reducing power plate failure rate, improve the reliability of communication devices, power supply system to reduce the load room, to achieve energy savings, savings in equipment costs.

[0031] 其次,将每块电源板的输出电功率的导线与隔离二极管正极连接,隔离二极管负极经均流电路与低压直流电源母线连接,选用的隔离二极管为肖特基二极管,反向隔离耐压为不小于DC60V。 [0031] Next, the wires of each of the output electric power of the power board isolation diode connected to the positive, the negative electrode via the current-blocking diode circuit connected to low voltage DC power bus, optional isolation diode is a Schottky diode, a reverse voltage isolation It is not less than DC60V.

[0032] 再次,采用均流输出控制法使每块电源板实现均流输出,使所有输出的低压电源功率在低压直流电源母线上叠加,共同承载通信设备群的业务负载,所述的均流输出控制法为下垂均流法,其电路详见图4所示,在DC/DC模块的输出端只需要串联很小的采样电阻,电流采样信号经过放大器放大后连接DC/DC模块的控制端TRM,用于调节本模块的输出电压。 [0032] Again, using the current-control method that the output of each power board achieve current output, low voltage power supply so that all output power is superimposed on the low voltage DC power supply bus, the common carrier communication device group of traffic load, the average flow the output control method for the droop flow method, which is detailed in the circuit shown in FIG. 4, at the output of DC / DC module requires only a very small sampling resistor in series, the current sensing amplifier connected to the signal after DC / DC module of the control terminal TRM, for regulating the output voltage of the module. 输出电流越大,输出电压越低,实现均流的U-1曲线。 The larger the output current, the output voltage is low, U-1 implemented curves stream. 由于串联电阳很小,损耗被降低,本发明运用下垂均流法可使其电路更加合理、更加稳定可靠。 Since the series electrical male small loss is reduced, the use of the present invention, it may be droop circuit flow method is more reasonable, more stable and reliable.

[0033] 以下结合不同制式通信设备的实例对本发明的具体实施方式作进一步的详细说明。 [0033] The following examples in conjunction with different modes of the communication device specific embodiments of the present invention will be described in further detail.

[0034] 实施例1:以本发明用于机架插卡式的多业务接入光传输设备PT_50S(6U)的电源组备份为例。 [0034] Example 1: In the present invention, the frame for multi-service access card type optical transmission equipment PT_50S (6U) Example backup power pack.

[0035] PT-50S(3U)是典型的机架插卡式通信设备,该通信设备有2个电源板插槽,可配置2块1:1备份的电源板,该型号的电源板接受DC-48V供电,输出低压直流DC12V给该通信设备的业务处理板使用,低压直流输出符合本发明所述的均流法控制要求,电源板的最大输出功率为100W。 [0035] PT-50S (3U) is a typical rack card communication device, the communication device power board has two slots, arranged two 1: 1 backup power board, power board for the model to accept DC -48V power supply, low voltage DC output to the service processing DC12V communication device using the plate, in line with low voltage DC output flow method according to the present invention, control requirements, maximum output power of the power supply plate is 100W. 以某工程需要在中心站配置10台该通信设备计,每台通信设备的业务处理板配置如表2所示: An engineering needs to be configured at the central station 10 the communication device count, each LPU communication apparatus configured as shown in Table 2:

[0036] 表2:每台通信设备的业务处理板配置一览表 [0036] Table 2: the service processing board communication device of each configuration list

Figure CN103094896AD00081

注:表2中的板卡类型在本发明中统称为业务处理板。 Note: in Table 2 referred to as card type service processing board of the present invention.

[0037] 采用本发明的备份方法配置的实施步骤如下: [0037] The method of the present invention is configured backup implementation steps are as follows:

[0038] 首先,将10台PT_50S(3U)通信设备的DC12V电源的低压直流电源母线分别与铜芯金属导线连接组成通信设备群,使该通信设备群的所有电源板输出的DC12V功率叠加。 [0038] First, the low voltage DC power source DC12V power bus 10 PT_50S (3U) are connected to the communication device copper core group of communication devices consisting of metal wires, so that all power DC12V power board communication device of the group of output stack. 该通信设备群设计了两个紧固式的柱形连接座,为了使连接电阻更小,可采用螺丝紧固的方法接线,一个连接DC12V,另一个接GND。 The group of communication devices designed Fastening two cylindrical connecting base, in order to make a smaller connection resistance, wiring screw fastening method may be employed, a connector DC12V, another access GND.

[0039] 其次,按照本发明的备份方法计算电源板的数量,得出电源板的最少配置数量为7块,富余功率=7X100-59X10 = 700-590 = 110W,富余电源功率大于I块电源板的功率,以满足最低备份要求,与原先不采用本发明的备份方法实现电源板备份的方式相比,电源板减少了13块,大大节省了通信设备的成本。 [0039] Next, calculated according to the number of the power board backup method of the present invention, the minimum number of derived power supply board configured to 7, surplus power = 7X100-59X10 = 700-590 = 110W, surplus power is greater than the power supply board block I power, to meet the minimum backup requirements, compared with the original method of the present invention without using backup power supply board implementations of backup power supply board 13 is reduced, saving the cost of the communication device. 但为增加电源组备份的可靠性,也可适当增加I至2块电源板的数量。 However, to increase the reliability of backup power pack can also be appropriate to increase the number of I to 2 power board. PT-50S(3U)通信设备在设计时具有电源板故障告警功能,并可将告警输出到通信设备网管后台或接声光告警设备,当其中某块电源板故障时,维护人员只需将故障板卡替换即可,使得业务系统运行保持连续而不中断。 PT-50S (3U) communication device having a power board designed fault alarm function, and the alarm device to the communication network or connected back sound and light alarm device, wherein when a piece of board power failure, the maintenance personnel need fault board can be replaced, making the business system to maintain continuous operation without interruption.

[0040] 再次,将电源板均匀地安装在10台PT_50S(3U)通信设备的电源板插卡位置,每台有电源板的通信设备均需要接入DC-48V电源,最佳方式是每台通信设备由不同的上位电源设备供电,以防止因上位供电电源故障或停电而影响多台通信设备运行,以体现分布式供电的优越性。 [0040] Again, the power board mounted on the power board uniformly 10 PT_50S (3U) of the position of the card communication device, each communication device has a need to access the power board are DC-48V power supply, the best way is for each different communication apparatus by the host device power supply, in order to prevent the upper power supply failure or power outage affecting multiple communications device is operated to reflect the advantages of distributed power supply.

[0041] 实施例2:以本发明用于机架插卡式的PT-60光传输设备的电源组备份为例。 [0041] Example 2: In the present invention, the power pack for the card rack type PT-60 Example backup optical transmission equipment.

[0042] 以某工程需要在同一机房配置2台PT-60光传输设备,作为用于实现话音、数据、视频接入的机架插卡式多业务通信设备,每台通信设备具有2个电源板插槽,每台通信设备在单独使用时,均能实现电源板的1+1备份,2台通信设备单独使用共需要4块电源板才能满足电源板的备份要求。 [0042] In an engineering need to configure the two PT-60 optical transmission devices in the same room, as a multi-service card rack for the communication device for voice, data, video access, each communication device having a power supply 2 board slots, each communication apparatus when used alone, can achieve 1 + 1 backup power board, two separate communication device requires a total of four power boards to meet the power requirements of the backup plate. 实施本发明的具体步骤如下: DETAILED embodiment of the present invention, the following steps:

[0043] 首先,计算按照实际配置的2台机架插卡式通信设备的总功耗,2台通信设备共配置5块业务处理板,总功耗为130瓦。 [0043] First, according to the total power consumption of 2 racks card communication device in the actual configuration, the communication device 2 arranged co-5 LPU 130 watts total.

[0044] 其次,根据公式2 X W3 > (W1-W2) > W3确定达到电源最少备份量的电源板型号和数量。 [0044] Next, according to the equation 2 X W3> (W1-W2)> W3 is determined to achieve the minimum backup power amount of a power board type and quantity. 每块电源板的最大输出功耗为80瓦,根据本发明的方法,需要3块电源板就能达到电源板的备份要求。 The maximum output power of each power board 80 watts, the method according to the present invention, three power boards need to be able to achieve the required backup power board. 只要将5块业务处理板均匀安装在2台设备上即可,一台安装2块业务处理板,另一台安装3块业务处理板,再将3块电源板分别安装在2台机架插卡式通信设备的电源板板位。 5 as long as the LPU uniformly mounted on the two devices can, a mounting plate 2 service processing, the other mounting plate 3 service processing, then the power supply board 3 is mounted on two racks, respectively inserted power plate board bit card communication device.

[0045] 再次,用本发明的方法将两台机架插卡式通信设备组合成通信设备群,使两台通信设备低压直流电源母线相连,实现3块电源板共同对5块业务处理板供电。 [0045] Again, the method of the present invention the two rack card communication device communication device are combined into groups, so that the two communication devices connected to a low voltage DC power bus, a common power supply board to achieve 3 to 5 LPU supply . 该通信设备群的富余功率=80X3-130 = 110瓦,大于单块电源板的输出功率,能够达到备份的目的。 The surplus power of the communication device group = 80X3-130 = 110 Watts, the output power is greater than the power supply monolithic plate, it is possible to achieve the purpose of backup.

[0046] 实施例3:以本发明用于组合式通信设备的电源备份为例。 [0046] Example 3: In the present invention, a backup power supply for modular communication device as an example.

[0047] 组合式通信设备应符合本发明所述的电源板的输入输出要求,确定每一种电源板的配置数量。 [0047] The combined input and output communication device should meet the requirements of the present invention, the power board, each arranged to determine the number of the power board.

[0048] 首先,实施步骤与实施例1相同,先计算出通信设备群正常运行的需要的总功耗。 [0048] First, the procedures as in Example 1, the first communications device calculates the total power consumption required for the normal operation of the group.

[0049] 其次,根据公式2 X W3 > (W1-W2) > W3确定达到电源最少备份量的电源板型号和 [0049] Next, according to the equation 2 X W3> (W1-W2)> W3 is determined to achieve the minimum backup power supply board type and amount of

数量; Number;

[0050] 再次,将采用铜芯金属导结作为连接所有通信设备的低压直流电源母线,组成组合式通信设备群,采用分散式DC-48V供电。 [0050] Again, the copper core metal conductor as a low voltage DC power bus node connecting all the communication devices, the communication device group composed of modular, decentralized DC-48V power supply.

[0051] 总之,本发明大大提高了通信设备电源板冗余备份的可靠性、稳定性,并大幅降低设备成本、降低设备功耗。 [0051] In summary, the present invention greatly improves the redundant power supply board communication device reliability, stability, and significantly reduce equipment costs, reduce power consumption. 若采用现有技术来实现电源组电源板备份,以上述PT-50S(3U)通信设备为例,则需要20块电源板来配置,不仅可靠性低,而且成本高、能耗大。 When using the prior art to realize the power board backup power pack, the above-described PT-50S (3U) communication device as an example, it is necessary to configure the power supply board 20, not only a low reliability, and high cost and energy.

[0052] 本发明经反复试验验证,取得了满意的应用效果。 [0052] The present invention is verified by trial and error, to achieve a satisfactory application.
