Description

通信电源蓄电池防反接电路及通信电源控制系统Communication power supply battery anti-reverse circuit and communication power control system 技术领域Technical field
本发明涉及通信电源技术领域，尤其涉及一种通信电源蓄电池防反接电路及通信电源控制系统。The invention relates to the technical field of communication power sources, in particular to a communication power supply battery anti-reverse circuit and a communication power control system.
背景技术Background technique
在通信电源中，常常需要配置一组或多组大容量的蓄电池作为后备电源给通信设备供电。随着通信技术的普及和发展，为实现网络覆盖的广泛性和全面性，越来越多的通信电源需要改造或者新建，而在通信电源的改造和新建的过程中，需要将蓄电池接入到通信电源系统中。但是由于施工人员的技术水平不高或者粗心，有可能把蓄电池接反，当蓄电池反接时会产生巨大的瞬间电流，又由于通信电源系统主回路中保险丝的熔断需要一定的时间，而这段时间足以损坏蓄电池和通信设备本身。蓄电池和通信设备的价格昂贵，且备货周期长，一旦损坏蓄电池和通信设备，将会造成区域性的通信中断，同时，还有可能危及操作人员的人身安全。因此，通信电源蓄电池防反接技术在通信电源系统中就显得尤为重要。In a communication power supply, it is often necessary to configure one or more sets of large-capacity batteries as backup power to supply power to the communication device. With the popularity and development of communication technologies, in order to realize the extensive and comprehensive coverage of network coverage, more and more communication power supplies need to be modified or newly built. In the process of transformation and construction of communication power supplies, batteries need to be connected to In the communication power system. However, because the technical level of the construction personnel is not high or careless, it is possible to reverse the battery. When the battery is reversely connected, a huge instantaneous current will be generated, and because the fuse in the main circuit of the communication power system needs to be blown for a certain period of time, this section Time is enough to damage the battery and the communication device itself. Batteries and communication equipment are expensive and have a long lead time. Once the battery and communication equipment are damaged, regional communication interruptions will occur, and at the same time, the personal safety of the operator may be jeopardized. Therefore, the communication power supply battery anti-reverse connection technology is particularly important in the communication power supply system.
然而，通信电源的蓄电池的容量较大(提供几十到上千安培的电流)，普通的二极管防反接电路或由M0S管控制的防反接电路已经不能适应通信电源蓄电池防反接的要求。相关技术中，通信电源行业所使用的蓄电池防反接方法主要有以下两种：(一)采用磁保持继电器控制直流接触器来实现蓄电池防反接；(二)通过常开继电器来控制直流接触器来实现蓄电池防反接。上述方法(一)的缺陷是：电路复杂，而且磁保持继电器的成本较高；上述方法(二)的缺陷是：电路同样较复杂，而且当通信电源系统中的控制器损坏时还会断开正常接入系统的蓄电池，使正常接入系统的蓄电池也不能给通信设备供电，造成通讯瘫痪等严重后果。However, the capacity of the communication power supply battery is large (providing tens to thousands of amps of current), the ordinary diode anti-reverse circuit or the anti-reverse circuit controlled by the MOS tube can not meet the requirements of anti-reverse connection of the communication power supply battery. . In the related art, the battery anti-reverse connection methods used in the communication power supply industry mainly have the following two types: (1) using a magnetic holding relay to control a DC contactor to realize anti-reverse connection of the battery; (2) controlling a direct current contact through a normally-on relay The device is used to achieve anti-reverse connection of the battery. The disadvantage of the above method (1) is that the circuit is complicated and the cost of the magnetic holding relay is high; the defect of the above method (2) is that the circuit is also complicated, and is disconnected when the controller in the communication power system is damaged. The battery that normally accesses the system makes the battery that normally accesses the system unable to supply power to the communication device, causing serious consequences such as communication failure.

本实施例通信电源蓄电池防反接电路的工作原理具体描述如下：The working principle of the anti-reverse circuit of the communication power supply battery of this embodiment is described as follows:
当所述通信电源系统由整流模块103供电时，通信电源正排GND及通信电源负排L正常有电。此时，如果蓄电池组101中任意一组蓄电池组发生反接时，即使此时控制器104没有给所述常闭继电器K1的线圈发出控制信号以切断蓄电池组101的接入，但是由于所述二极管D6或者所述二极管D7导通，所述常闭继电器K1的线圈还是有电流通过，使得所述常闭继电器K1的常闭触点1断开，从而切断了所述常开直流接触器KM的线圈的工作回路，使得所述常开直流接触器KM的触点断开，使得蓄电池组101不能接入到所述通信电源系统中，从而使得所述通信电源系统得到保护；When the communication power supply system is powered by the rectifier module 103, the communication power supply is positively GND and the communication power supply negative row L is normally powered. At this time, if any one of the battery packs in the battery pack 101 is reversely connected, even if the controller 104 does not issue a control signal to the coil of the normally-closed relay K1 to cut off the access of the battery pack 101, The diode D6 or the diode D7 is turned on, and the coil of the normally-closed relay K1 still has a current passing through, so that the normally-closed contact 1 of the normally-closed relay K1 is turned off, thereby cutting off the normally-on DC contactor KM. a working circuit of the coil, such that the contact of the normally open DC contactor KM is disconnected, so that the battery pack 101 cannot be accessed into the communication power system, thereby enabling the communication power system to be protected;
当整流模块103不工作且蓄电池组101中已有一组及一组以上的蓄电池组接入到所述通信电源系统时，则通信电源正排GND及通信电源负排L同样正常有电。此时，如蓄电池组101中有任意一组蓄电池组发生了反接，则与上面情况一样，即使此时控制器104没有给所述常闭继电器K1的线圈发出控制信号以切断蓄电池组101的接入，但是由于所述二极管D6或者所述二极管D7导通，所述常闭继电器K1的线圈还是有电流通过，使得所述常闭继电器K1的常闭触点1断开，从而切断了所述常开直流接触器KM的线圈的工作回路，使得所述常开直流接触器KM的触点断开，使得蓄电池组101不能 接入到所述通信电源系统中，从而使得所述通信电源系统得到保护；When the rectifier module 103 does not work and a group and more than one battery pack in the battery pack 101 are connected to the communication power supply system, the communication power supply positive GND and the communication power negative row L are also normally powered. At this time, if any group of battery packs in the battery pack 101 is reversed, as in the above case, even if the controller 104 does not issue a control signal to the coil of the normally-closed relay K1 to cut off the battery pack 101. Accessing, but because the diode D6 or the diode D7 is turned on, the coil of the normally-closed relay K1 still has a current passing through, so that the normally-closed contact 1 of the normally-closed relay K1 is turned off, thereby cutting off the The working circuit of the coil of the normally open DC contactor KM causes the contacts of the normally open DC contactor KM to be disconnected, so that the battery pack 101 cannot Accessing to the communication power system such that the communication power system is protected;
当整流模块103不工作，且没有蓄电池组接入到所述通信电源系统时，则通信电源正排GND及通信电源负排L无电。此时，如果蓄电池组发生反接，则由于控制器104和通信电源正排GND及通信电源负排L均没电，因此所述常开直流接触器KM的线圈不导通，从而所述常开直流接触器KM的触点是断开的，这样蓄电池组同样不能接入到所述通信电源系统，同样，使得所述通信电源系统得到了保护；When the rectifier module 103 does not work, and no battery pack is connected to the communication power supply system, the communication power supply is GND and the communication power supply negative row L has no power. At this time, if the battery pack is reversed, since the controller 104 and the communication power supply positive row GND and the communication power source negative row L are both dead, the coil of the normally open DC contactor KM is not turned on, so that the The contact of the open DC contactor KM is disconnected, so that the battery pack cannot be connected to the communication power supply system as well, so that the communication power supply system is protected;
当整流模块103工作或者蓄电池组101中已有蓄电池组接入到所述通信电源系统中，即通信电源正排GND及通信电源负排L已经有电。此时，如果有蓄电池组正常接入，所述二极管D6或者所述二极管D7都反向截止，除非这时控制器104给出下电控制信号，否则所述常闭继电器K1的线圈不能工作，其常闭触点处于闭合状态，所述常开直流接触器KM的线圈回路导通，使得所述常开直流接触器KM的触点处于闭合状态，从而使得蓄电池组101可以正常的接入到所述通信电源系统为所述通信电源系统供电；When the rectifier module 103 is working or an existing battery pack in the battery pack 101 is connected to the communication power supply system, that is, the communication power supply positive row GND and the communication power supply negative row L are already powered. At this time, if a battery pack is normally connected, the diode D6 or the diode D7 is reversely turned off. Unless the controller 104 gives a power-down control signal at this time, the coil of the normally-closed relay K1 cannot operate. The normally closed contact is in a closed state, and the coil circuit of the normally open DC contactor KM is turned on, so that the contact of the normally open DC contactor KM is in a closed state, so that the battery pack 101 can be normally accessed. The communication power system supplies power to the communication power system;
当整流模块不工作，且没有蓄电池组接入到所述通信电源系统，即通信电源正排GND及通信电源负排L没有电。此时，如果想接入蓄电池组，仅用蓄电池组供电，蓄电池组并不能直接接入到所述通信电源系统，只能在控制器104的控制下或者人工确定无误后手动按下应急模块105的手动按键T，使蓄电池组接入到所述通信电源系统(即接入到通信电源正排GND和通信电源负排L之间)。由此，可以避免蓄电池组接入所述通信电源系统后使所述通信电源系统立刻上电而发生不确定的事故。When the rectifier module does not work, and no battery pack is connected to the communication power system, that is, the communication power source is in the positive line GND and the communication power source negative line L has no power. At this time, if the battery pack is to be connected, only the battery pack is used for power supply, and the battery pack cannot directly access the communication power supply system, and the emergency module 105 can be manually pressed only under the control of the controller 104 or manually determined. The manual button T connects the battery pack to the communication power system (ie, is connected between the communication power supply positive row GND and the communication power source negative row L). Thereby, it is possible to prevent the communication power supply system from being powered on immediately after the battery pack is connected to the communication power supply system, and an uncertain accident occurs.
