为使本说明书实施例的目的、技术方案和优点更加清楚，下面将结合本说明书实施例中的附图，对本说明书实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of this specification more clear, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification.

实施例Example
首先，需要说明的是，一般来说，相控阵雷达包括数量众多的TR组件，即多个TR组件组成了TR组件阵列，TR组件作为有源相控阵雷达的核心部件之一，对于各个电源的加电顺序或掉电顺序具有严格的要求，即设有预设的顺序标准，如果加电顺序或掉电顺序不正确，则可能导致TR组件工作异常甚至是损坏，因此，确保各个电源的加电顺序或掉电顺序正确，对于确保TR组件正常运行具有重要意义。其中，TR组件的各个电源包括但不限于栅极电源VG(Voltage Gate)、第一工作电源VDP(Device Power Voltage，器件电源电压)、第二工作电源VEE(Emitter Voltage，发射极电源电压)，根据TR组件的供电顺序要求，栅极电源VG的供电顺序应当在第一工作电源VDP和第二工作电源VEE之前，第一工作电源VDP和第二工作电源VEE的供电顺序没有明确限定。First of all, it should be noted that, generally speaking, a phased array radar includes a large number of TR components, that is, a plurality of TR components form a TR component array. As one of the core components of an active phased array radar, the TR component has strict requirements for the power-on sequence or power-off sequence of each power supply, that is, a preset sequence standard is set. If the power-on sequence or power-off sequence is incorrect, it may cause the TR component to work abnormally or even be damaged. Therefore, ensuring that the power-on sequence or power-off sequence of each power supply is correct is of great significance for ensuring the normal operation of the TR component. Among them, the various power supplies of the TR component include but are not limited to the gate power supply VG (Voltage Gate), the first working power supply VDP (Device Power Voltage), and the second working power supply VEE (Emitter Voltage). According to the power supply sequence requirements of the TR component, the power supply sequence of the gate power supply VG should be before the first working power supply VDP and the second working power supply VEE, and the power supply sequence of the first working power supply VDP and the second working power supply VEE is not clearly defined.
基于上述，本申请实施例在下文中提出了一种TR组件供电控制电路，用于确保栅极电源VG一定在第一工作电源VDP和第二工作电源VEE之前向TR组件进行加电，以下将对其实现原理进行详细说明。Based on the above, the embodiment of the present application proposes a TR component power supply control circuit below, which is used to ensure that the gate power supply VG must power the TR component before the first working power supply VDP and the second working power supply VEE.

所述状态监测电路被配置为根据栅极电源的工作状态，向所述控制器输出与所述工作状态对应的反馈信号，所述工作状态包括已加电状态和未加电状态；The state monitoring circuit is configured to output a feedback signal corresponding to the working state to the controller according to the working state of the gate power supply, wherein the working state includes a powered state and a non-powered state;
所述顺序控制电路被配置为根据所述栅极电源的已加电信号，将工作电源输出至所述电源调制电路；The sequence control circuit is configured to output the working power supply to the power modulation circuit according to the powered-on signal of the gate power supply;
所述控制器被配置为根据与所述已加电状态对应的反馈信号，向所述电源调制电路发送所述工作电源的控制信号；The controller is configured to send a control signal of the working power supply to the power modulation circuit according to a feedback signal corresponding to the powered-on state;

The control signal can guide the power modulation circuit to send the working power supply to the sending part or the receiving part of the TR component, so as to meet the mutually exclusive requirement that the sending part and the receiving part of the TR component do not receive power at the same time, further ensuring the accuracy of the power-on sequence and improving the working efficiency of the TR component.

需要说明的是，所述状态监测电路的工作原理具体如下：It should be noted that the working principle of the state monitoring circuit is as follows:
当栅极电源VG未加电时，则第一NPN型三极管Q1的发射极未获取到电源输入，因此第一NPN型三极管Q1不导通，3.3V的工作电压VCC作为高电平信号输出至控制器，以便控制器获知栅极电源VG未加电；反之，当栅极电源VG已加电时，则第一NPN型三极管Q1的发射极获取到电源输入，因此第一NPN型三极管Q1导通，0.1V的电压作为低电平信号输出至控制器，以便控制器获知栅极电源VG已加电。When the gate power supply VG is not powered, the emitter of the first NPN transistor Q1 does not obtain the power input, so the first NPN transistor Q1 is not turned on, and the 3.3V operating voltage VCC is output to the controller as a high-level signal, so that the controller knows that the gate power supply VG is not powered; conversely, when the gate power supply VG is powered, the emitter of the first NPN transistor Q1 obtains the power input, so the first NPN transistor Q1 is turned on, and a voltage of 0.1V is output to the controller as a low-level signal, so that the controller knows that the gate power supply VG is powered.

需要说明的是，所述顺序控制电路的工作原理具体如下：It should be noted that the working principle of the sequential control circuit is as follows:
当第二NPN型三极管Q2的发射极未接收到栅极电源VG已加电信号时，则第二NPN型三极管Q2的发射极未获取到电源输入，因此第二NPN型三极管Q2不导通，进而第一PMOS管U1的第二端未导通，第一PMOS管U1的第三端不输出工作电源，反之，当第二NPN型三极管Q2的发射极接收到栅极电源VG已加电信号时，则第二NPN型三极管Q2的发射极获取到电源输入，因此第二NPN型三极管Q2导通，进而第一PMOS管U1的第二端导通，第一PMOS管U1的第三端输出工作电源。When the emitter of the second NPN transistor Q2 does not receive the gate power supply VG power-on signal, the emitter of the second NPN transistor Q2 does not obtain the power input, so the second NPN transistor Q2 is not turned on, and then the second end of the first PMOS tube U1 is not turned on, and the third end of the first PMOS tube U1 does not output the working power. Conversely, when the emitter of the second NPN transistor Q2 receives the gate power supply VG power-on signal, the emitter of the second NPN transistor Q2 obtains the power input, so the second NPN transistor Q2 is turned on, and then the second end of the first PMOS tube U1 is turned on, and the third end of the first PMOS tube U1 outputs the working power.

需要说明的是，由于T/R组件的收发件和接收件的加电时间是分时加电，即发射件加电时，接收件不加电，反之，接收件加电时，发射件不加电，即二者之间的加电时间存在互斥关系。基于此，本申请实施例通过设置信号处理电路来获取控制信号，并根据控制信号生成触发信号，以触发将所述工作电源分时供应至所述TR组件的发送件或接收件。It should be noted that since the power-on time of the transceiver and the receiving part of the T/R component is time-sharing, that is, when the transmitting part is powered on, the receiving part is not powered on, and vice versa, when the receiving part is powered on, the transmitting part is not powered on, that is, there is a mutually exclusive relationship between the power-on times of the two.
