Compared with the existing Mechanical action control. In this application, the action of the elevator brake is controlled by outputting electrical signals from the main circuit of the brake power supply, directly replacing the mechanical control of the brake contactor, directly avoiding the high safety hazards of using the brake contactor. Issue with loud startup noise.

本申请提出一种电梯非隔离安全抱闸电源。This application proposes a non-isolated safety brake power supply for an elevator.
在本申请一实施例中，如图1所示，该电梯非隔离安全抱闸电源包括安全控制模块10和抱闸电源主回路20；In an embodiment of the present application, as shown in Figure 1, the elevator non-isolated safety brake power supply includes a safety control module 10 and a brake power main circuit 20;
所述安全控制模块10的输入端接入电梯安全回路30中，所述安全控制模块10的输出端与所述抱闸电源主回路20的受控端连接；The input end of the safety control module 10 is connected to the elevator safety circuit 30, and the output end of the safety control module 10 is connected to the controlled end of the brake power main circuit 20;
所述抱闸电源主回路20的输入端经由过流保护装置与输入电源连接，所述抱闸电源主回路20的输出端与电梯抱闸连接，其中过流保护装置用于防止抱闸电源主回路20出现过流和/或短路时，电梯非隔离安全抱闸电源不能够正常运行的情况；The input end of the brake power main circuit 20 is connected to the input power supply via an overcurrent protection device, and the output end of the brake power main circuit 20 is connected to the elevator brake. The overcurrent protection device is used to prevent the brake power supply from overcurrent. When overcurrent and/or short circuit occurs in circuit 20, the elevator's non-isolated safety brake power supply cannot operate normally;
所述抱闸电源主回路20，用于为所述电梯抱闸供电；The brake power main circuit 20 is used to supply power to the elevator brake;
所述安全控制模块10，用于根据所述电梯安全回路30的输出信号，开通或关断所述抱闸电源主回路20与所述电梯抱闸的电连接。The safety control module 10 is used to open or close the electrical connection between the main brake power circuit 20 and the elevator brake according to the output signal of the elevator safety circuit 30 .
所述电梯安全回路30，用于在检测到电梯存在制停需求时，即串联在电梯安全回路30中的电梯各设备开关存在打开的情况，判定为电梯存在制停需求，立即切断向所述安全控制模块10输出电源的电源回路；The elevator safety circuit 30 is used to detect that there is a need to stop the elevator, that is, when the switches of the elevator equipment connected in series in the elevator safety circuit 30 are turned on, it determines that there is a need to stop the elevator and immediately cuts off the supply to the elevator. The power supply circuit for the output power of the safety control module 10;
所述抱闸电源主回路20，用于在所述电梯安全回路30处于断路时，即电梯安全回路30中的某一开关打开时，此时电源端输出的电压因电梯安全回路30的短路，不能输出至抱闸电源主回路20中，进而使得抱闸电源主回路20中不存在电流的流通，从而切断向电梯抱闸进行供电的供电电源。The brake power main circuit 20 is used when the elevator safety circuit 30 is in an open circuit, that is, when a certain switch in the elevator safety circuit 30 is turned on. At this time, the voltage output by the power terminal is due to the short circuit of the elevator safety circuit 30. It cannot be output to the main circuit of the brake power supply 20, so that there is no current flowing in the main circuit of the brake power supply 20, thereby cutting off the power supply supplying power to the elevator brake.
因为现有的电梯抱闸控制电路中所运用到的抱闸接触器在启动过程中会产生巨大的噪声，不论是对乘体用户还是周边用户，都会造成不良的居住体验，同时抱闸接触器的触点释放时存在的触点拉弧会提升抱闸接触器的故障率，使得电梯存在停梯困人的不利情况，因此基于上述问题，本申请提出了将现有的电梯安全回路30末端通过抱闸继电器Y点来控制抱闸接触器替换为通过抱闸电源主回路20对输出至电梯抱闸的电源进行控制，抱闸接触器被抱闸电源主回路20所代替，实现从根源上解决抱闸接触器存在的安全隐患和启动噪声大的问题。Because the brake contactor used in the existing elevator brake control circuit will produce huge noise during the startup process, it will cause a bad living experience for both the passengers and surrounding users. At the same time, the brake contactor The contact arcing when the contact is released will increase the failure rate of the brake contactor, causing the elevator to have the unfavorable situation of trapping people when the elevator stops. Therefore, based on the above problems, this application proposes to connect the end of the existing elevator safety circuit 30 The brake contactor is controlled through the Y point of the brake relay and the power output to the elevator brake is controlled through the brake power main circuit 20. The brake contactor is replaced by the brake power main circuit 20 to achieve the goal from the root. Solve the potential safety hazards of the brake contactor and the problem of high starting noise.
具体地，如图2所示的，所述安全控制模块10，用于通过所述电梯安全回路30的输出信号生成安全电源或安全使能信号对所述电梯抱闸进行控制。Specifically, as shown in FIG. 2 , the safety control module 10 is used to generate a safety power supply or a safety enable signal through the output signal of the elevator safety circuit 30 to control the elevator brake.
当电梯安全回路30上的某一电梯设备的开关打开时，电梯安全回路30就会存在断路，使得电梯安全回路30末端无法对应生成用于控制电梯抱闸的输出信号，安全控制模块10上就会因不存在输出信号而无法进行安全电源或安全使能信号的生成，而安全电源或安全使能信号是对电梯抱闸进行供电的基础，只有在电梯安全回路30上的电梯设备的开关全部闭合时，安全控制模块10才能根据电梯安全回路30末端的输出信号，生成所需的安全电源或安全使能信号对电梯抱闸进行供电。When a switch of a certain elevator equipment on the elevator safety circuit 30 is turned on, there will be a circuit break in the elevator safety circuit 30 , so that the end of the elevator safety circuit 30 cannot correspondingly generate an output signal for controlling the elevator brake, and the safety control module 10 Because there is no output signal, the safety power supply or safety enable signal cannot be generated, and the safety power supply or safety enable signal is the basis for powering the elevator brake. Only all switches of the elevator equipment on the elevator safety circuit 30 When closed, the safety control module 10 can generate the required safety power or safety enable signal to power the elevator brake according to the output signal at the end of the elevator safety circuit 30 .
安全控制模块10内部包含有电源生成芯片，该芯片在安全控制模块10接收到输出信号时会开启，进而生成安全电源并输出，若安全控制模块10未接收到输出信号，则该芯片会关闭，而关闭后的电源生成芯片不具备生成安全电源的功能。The safety control module 10 contains a power generation chip inside. When the safety control module 10 receives an output signal, the chip will be turned on to generate safety power and output it. If the safety control module 10 does not receive an output signal, the chip will be turned off. The power generation chip that is turned off does not have the function of generating safe power.
进一步的，所述安全控制模块10，用于根据所述电梯安全回路30的输出电源生成安全使能信号，所述安全使能信号用于控制PWM信号传输通道的开通或关断；Further, the safety control module 10 is used to generate a safety enable signal according to the output power of the elevator safety circuit 30, and the safety enable signal is used to control the opening or closing of the PWM signal transmission channel;
所述抱闸电源主回路20，用于根据PWM信号为所述电梯抱闸进行供电。The brake power main circuit 20 is used to provide power to the elevator brake according to the PWM signal.
进一步的，所述安全控制模块10包括微处理器；Further, the safety control module 10 includes a microprocessor;
所述安全控制模块10，用于根据所述电梯安全回路30的输出电源生成安全电源；The safety control module 10 is used to generate safety power according to the output power of the elevator safety circuit 30;
所述安全电源，用于控制所述微处理器的启动或停止。The safety power supply is used to control the start or stop of the microprocessor.
微处理器和电源生成芯片一样安置在安全控制模块10内部，不同于电源生成芯片，微处理器是用于在安全控制模块10接收到电梯安全回路30末端的输出信号时生成安全使能信号，该安全使能信号用于向非隔离电源转换电路40输出PWM信号。The microprocessor is placed inside the safety control module 10 like the power generation chip. Different from the power generation chip, the microprocessor is used to generate a safety enable signal when the safety control module 10 receives the output signal from the end of the elevator safety circuit 30. The safety enable signal is used to output a PWM signal to the non-isolated power conversion circuit 40 .
需注意的是，即便电源生成芯片因某些特殊情况在安全控制模块10未接收到输出信号时依旧处于开启状态，但只要此时的微处理器未生成安全使能信号并输出PWM信号，未关闭的电源生成芯片就不具备使非隔离电源转换电路40导通的作用。It should be noted that even if the power generation chip is still on when the safety control module 10 does not receive an output signal due to some special circumstances, as long as the microprocessor does not generate a safety enable signal and output a PWM signal at this time, the power generation chip will not The turned off power generation chip does not have the function of turning on the non-isolated power conversion circuit 40 .
进一步的，所述安全控制模块10的输入端接入所述电梯安全回路30的末端。Further, the input end of the safety control module 10 is connected to the end of the elevator safety circuit 30 .
进一步的，所述抱闸电源主回路20还包括非隔离电源转换电路40，所述非隔离电源转换电路40的输入端与所述安全控制模块10的输出端相连接；Further, the brake power main circuit 20 also includes a non-isolated power conversion circuit 40, the input end of the non-isolated power conversion circuit 40 is connected to the output end of the safety control module 10;
所述非隔离电源转换电路40为非隔离BUCK-BOOT（升降压使）拓扑电路，所述非隔离BUCK-BOOT拓扑电路包括开关管Q1、电感L1、二极管D1和电容C1；The non-isolated power conversion circuit 40 is a non-isolated BUCK-BOOT (boost-buck) topology circuit. The non-isolated BUCK-BOOT topology circuit includes a switch Q1, an inductor L1, a diode D1 and a capacitor C1;
所述开关管Q1的栅极与所述安全控制模块10的输出端相连接，所述开关管Q1的源极与所述二极管D1的负极相连接，所述电感L1和电容C1分别并联在所述二极管D1的负极和正极上。The gate of the switch Q1 is connected to the output end of the safety control module 10, the source of the switch Q1 is connected to the cathode of the diode D1, and the inductor L1 and the capacitor C1 are connected in parallel. on the cathode and anode of diode D1.
开关管Q1用于接收安全控制模块10发送的安全电源或PWM信号，安全电源用来给开关管Q1驱动提供电源，PWM信号用来驱动开关管Q1动作。The switch tube Q1 is used to receive the safety power supply or the PWM signal sent by the safety control module 10. The safety power supply is used to provide power for driving the switch tube Q1, and the PWM signal is used to drive the switch tube Q1.
其中，开关管Q1可以使用IGBT（Insulated Gate Bipolar Transistor，绝缘栅双极型晶体管）或者MOSFET（Metal-Oxide-Semiconductor Field-Effect Transistor，金氧半场效晶体管）。Among them, the switch tube Q1 can use IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor) or MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor, Metal Oxide Semiconductor Field Effect Transistor).
当开关管Q1闭合时，通过开关管Q1输出的直流电源电压通过电感L1直接返回，在电感L1上进行储能，此时的电容C1放电为电梯抱闸进行供电，使得电梯抱闸得电松开。When the switch Q1 is closed, the DC power supply voltage output by the switch Q1 returns directly through the inductor L1 and stores energy on the inductor L1. At this time, the capacitor C1 discharges to power the elevator brake, causing the elevator brake to be loosened. open.
当开关管Q1断开时，电感L1两端电压极性翻转，电感L1上产生反向电动势，使得二极管D1从截止变成导通，此时的电感L1为电梯抱闸进行供电和电容C1进行充电，但由于此时的电流流向使得输出至电梯抱闸的稳压直流电源电压为负值，即输出至电梯抱闸的稳压直流电源电压的极性相反，所以此时输出至电梯抱闸的电压并不能对电梯抱闸起到真正的供电作用，使得电梯抱闸失电，电梯制停。When the switch Q1 is turned off, the polarity of the voltage at both ends of the inductor L1 reverses, and a reverse electromotive force is generated on the inductor L1, causing the diode D1 to change from cut-off to conduction. At this time, the inductor L1 supplies power to the elevator brake and capacitor C1 Charging, but due to the current flow direction at this time, the voltage of the regulated DC power supply output to the elevator brake is negative, that is, the polarity of the voltage of the regulated DC power supply output to the elevator brake is opposite, so the voltage output to the elevator brake is reversed. The voltage cannot really provide power to the elevator brake, causing the elevator brake to lose power and the elevator to stop.
所述非隔离电源转换电路40，用于在导通时将接收的直流电源进行转换，生成电梯抱闸所需的供电电源。The non-isolated power conversion circuit 40 is used to convert the received DC power when it is turned on to generate the power supply required for the elevator brake.
非隔离电源转换电路40导通，说明安全控制模块10顺利生成安全电源或安全使能信号，生成的安全电源或安全使能信号会使得非隔离电源转换电路40导通，将接收的直流电源转换成稳压直流输出至电梯抱闸，为电梯抱闸提供供电电源。The non-isolated power conversion circuit 40 is turned on, indicating that the safety control module 10 successfully generates a safe power supply or a safety enable signal. The generated safety power supply or safety enable signal will cause the non-isolated power conversion circuit 40 to be turned on, converting the received DC power. The stabilized DC output is output to the elevator brake to provide power supply for the elevator brake.
当非隔离电源转换电路40不导通时，说明安全控制模块10未能顺利生成安全电源或安全使能信号使得非隔离电源转换电路40导通，未导通的非隔离电源转换电路40是不具备将直流电源转换为稳压直流输出至电梯抱闸，为电梯抱闸进行供电的，而未接收到供电电源的电梯抱闸会处于失电状态，进而使得电梯制停。When the non-isolated power conversion circuit 40 is not conductive, it means that the safety control module 10 failed to successfully generate a safe power supply or a safety enable signal to cause the non-isolated power conversion circuit 40 to conduct. The non-conducted non-isolated power conversion circuit 40 is not conductive. It has the ability to convert DC power into a regulated DC output to the elevator brake to provide power for the elevator brake. However, the elevator brake that does not receive power supply will be in a power-off state, causing the elevator to stop.
进一步地，所述抱闸电源主回路20的输出端与抱闸制动线圈L2的初级线圈相接；Further, the output end of the brake power main circuit 20 is connected to the primary coil of the brake coil L2;
所述抱闸制动线圈L2的初级线圈与所述非隔离电源转换电路40的供电电源输出端相连，所述抱闸制动线圈L2的次级线圈与所述电梯抱闸电连接。The primary coil of the brake coil L2 is connected to the power supply output end of the non-isolated power conversion circuit 40, and the secondary coil of the brake coil L2 is electrically connected to the elevator brake.
抱闸制动线圈L2用于为电梯抱闸进行供电，当非隔离电源转换电路40导通并输出稳压直流电源电压时，抱闸制动线圈L2的初级线圈会接收该稳压直流电源电压，并通过抱闸制动线圈L2的次级线圈将稳压直流电源电压输出至电梯抱闸中，为电梯抱闸进行供电，电梯抱闸得电松开，不进行电梯制停。The brake coil L2 is used to power the elevator brake. When the non-isolated power conversion circuit 40 is turned on and outputs a regulated DC power supply voltage, the primary coil of the brake brake coil L2 will receive the regulated DC power supply voltage. , and outputs the regulated DC power supply voltage to the elevator brake through the secondary coil of the brake brake coil L2 to supply power to the elevator brake. The elevator brake is powered to release without braking the elevator.
当非隔离电源转换电路40不导通时，此时就不存在稳压直流电源电压的生成，进而就不存在抱闸制动线圈L2的次级线圈将稳压直流电源电压输出至电梯抱闸中，为电梯抱闸进行供电的情况，因此此时的电梯抱闸失电抱紧，电梯制停。When the non-isolated power conversion circuit 40 is not conductive, there is no generation of the regulated DC power supply voltage, and then there is no secondary coil of the brake coil L2 to output the regulated DC power supply voltage to the elevator brake. , the elevator brake is supplied with power, so at this time the elevator brake loses power and tightens, and the elevator stops.
进一步的，所述抱闸电源主回路20还包括直流电源端VIN；Further, the brake power main circuit 20 also includes a DC power terminal VIN;
所述直流电源端VIN接在所述安全控制模块10的输出端上；The DC power supply terminal VIN is connected to the output terminal of the safety control module 10;
所述直流电源端VIN，用于为所述非隔离电源转换电路40进行供电。The DC power terminal VIN is used to power the non-isolated power conversion circuit 40 .
进一步地，所述电梯安全回路30包括交流电源端AC和整流电路；Further, the elevator safety circuit 30 includes an AC power terminal AC and a rectifier circuit;
所述交流电源端AC的输出端与所述整流电路的输入端相连接。The output terminal of the AC power terminal AC is connected to the input terminal of the rectifier circuit.
在本实施例中，交流电源端AC输出的是220V的交流电源电压，而非隔离电源转换电路40是对高压直流电压进行转换，因此，在将交流电源端AC输出的交流电源电压输出至非隔离电源转换电路40之前，需先对220V的交流电源电压进行整流，经由整流模块后的交流电源电压转化为300V的高压直流电源电压，并将高压直流电源电压输出至抱闸电源主回路20中的直流电源端VIN中，对非隔离电源转换电路40进行供电。In this embodiment, the AC power supply terminal AC outputs an AC power voltage of 220V, and the non-isolated power conversion circuit 40 converts a high-voltage DC voltage. Therefore, the AC power supply voltage output by the AC power supply terminal AC is output to the non-isolated power supply. Before isolating the power conversion circuit 40, the 220V AC power supply voltage needs to be rectified first. The AC power supply voltage after passing through the rectifier module is converted into a 300V high-voltage DC power supply voltage, and the high-voltage DC power supply voltage is output to the brake power supply main circuit 20. The DC power terminal VIN supplies power to the non-isolated power conversion circuit 40 .
