为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作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。
参见图1，图1为本发明一实施例提供的注射泵控制的结构示意图。注射泵控制系统100位于注射泵200中，用于控制注射泵200的操作，注射泵控制系统100为双控制器系统，包括双控制器单元10，双控制器单元10包括连接在一起的监控控制器11和主控制器12，它们均为MCU（Microcontroller Unit，微控制单元）。监控控制器11的具体型号可以是STM32，主控制器12的具体型号可以是STM32F407ZGT6。监控控制器11还与开关按键和供电电源连接，在开关按键被接通时，注射泵开机，监控控制器11控制供电电源开始为注射泵供电，监控控制器11可以主动获取或被动接收来自主控制器12的通信信号，通信信号的作用是根据双方发送和回复的内容判断双方是否保持正常通信，该通信信号具体可以是心跳信号。当主控制器12发送的通信信号异常时，表示主控制器12可能因故障无法继续工作，监控控制器11先关闭注射泵的电机，再关闭注射泵，即切断注射泵的供电电源，触发应急临时电源启动为报警模块供电，然后控制报警模块进行报警。
进一步地，当注射泵开机开始工作后，主控制器12对注射泵的运行数据进行采样，具体采集注射泵的电机、屏幕、按键、传感器、槽型光耦、限位开关、声光报警模块、存储装置和外接电源等运行数据，并判断采样数据是否存在触发报警的异常，若存在则触发报警模块进行报警。采样数据异常触发的报警与主控制器12出现故障触发的报警模式不同，相比之下，主控制器12出现故障的报警方式提醒度更高，例如报警灯闪烁的频率最高，颜色为红色，报警声音为最高音量，同时伴随注射泵的屏幕上红字闪烁等。
参见图2，图2为本发明一实施例提供的注射泵控制系统的结构示意图。注射泵系统包括该注射泵控制系统，该注射泵控制系统包括：双控制器单元10、双供电单元20、数据采集单元30、按键控制单元40和报警模块50；

应急临时电源12还连接供电电源21和报警模块50，检测到供电电源21停止供电后，应急临时电源12启动，并替代供电电源21为报警模块50供电。
按键控制单元40包括控制开关41，监控控制器11连接控制开关41，在控制开关41被接通时，监控控制器11启动供电电源21开始供电，为包括监控控制器11和主控制器12在内的注射泵供电。
主控制器12用于向监控控制单元11发送通信信号，以及，控制数据采集单元30采集注射泵的运行数据，并根据该运行数据判断注射泵运行是否正常，若出现异常则控制报警模块50进行报警。该运行数据包括注射泵的电机、供电电源、应急临时电源、显示屏、注射装置以及各种按键等的运行数据，该运行数据可表征注射泵的运行状态是否正常。
监控控制器11用于持续获取主控制器12的通信信号，并当该通信信号异常时，确认主控制器12出现预设故障，切断注射泵的供电电源21并发出报警信号，切断供电可触发应急临时电源12启动，对报警模块50进行供电，报警模块50根据该报警信号进行报警。此时的报警为最高级别的报警，提示性最强，最高级别的报警包括报警的音量最大，蜂鸣振动频率最高、红字闪烁以及持续时间最长等。
该通信信号是每隔预设时长，监控控制器11向主控制器12获取一次，或者，主控制器12主动向监控控制器11发送一次，监控控制器11通过获取的该通信信号的时间和内容，确定主控制器12是否发生了故障。
上述注射泵控制系统还可以有另一种连接方式：监控控制器11连接主控制器12，以及连接注射泵的供电电源21、应急临时电源12和报警模块50；
监控控制器11获取主控制器12的通信信号，并当通信信号异常时，监控控制器11切断注射泵的供电电源21并启动应急临时电源12对报警模块50供电，监控控制器11还用于控制报警模块50进行报警。

进一步地，注射泵还包括电机，具体为步进电机60，监控控制器11和主控制器12分别与注射泵的电机60连接，监控控制器11用于当该通信信号异常时，控制电机60按照预设缓停模式停止运转，该缓停模式设置了电机60降速为0所需的时长和降速的规则，先停止电机60的运转，再关闭供电电源13。
进一步地，主控制器12与电机60连接，控制电机60驱动注射器的推柄的推拉，推柄进而推拉注射器的注射推杆，完成注射操作。
进一步地，主控制器12还与注射泵的主设备接口70连接，射频主机，例如射频消融仪，通过与注射泵连接，控制注射泵完成注射任务。当检测到主设备接口70与射频主机被主设备控制线连通时，主控制器12用于控制注射泵进入从设备模式，即，控制注射泵的输入设备停止响应输入操作，输入设备包括触控屏、鼠标、键盘等。
按键控制单元40还包括静音开关42，主控制器12还与静音开关42连接，当静音开关42被接通时，主控制器12检测当前输出的声音信号，并确定输出声音信号的模块，根据该模块的性质选择切断声音信号的输出方式，例如，切断发声结构的输出端，或者，切断该模块的输入端的信号输入，并切断该声音信号的输出，该声音信号，例如是报警模块50中的报警蜂鸣声或报警声音。

注射位置检测装置32包括光耦和挡光片，挡光片被步进电机60驱动进行直线运动，与注射器的推杆同步运动，通过挡光片与光耦的配合，可得知注射器的推杆位置，进一步根据预设算法计算注射器的剩余注射量等工作状态数据。
主控制器12获取步进电机60、压力检测传感器31、注射位置检测装置32和触控屏80的工作状态数据，并根据这些数据判断对应的模块或装置工作是否正常，若不正常，则按照预设的处理逻辑触发报警模块50进行报警。报警模块50的报警模式为声、光、振动等多种方式的一种或多种组合。

进一步地，主控制器控制数据采集单元采集注射泵的运行数据，并根据该运行数据判断注射泵运行是否正常，若出现异常则控制该注射泵的报警模块进行报警。可以通过对比该运行数据与系统中预设的标准数据，来确认注射泵的工作状态是否正常。
步骤S503、监控控制器持续获取主控制器发送的通信信号，并当通信信号异常时，切断供电电源的供电并发送报警信号，切断供电触发应急临时电源启动并对报警模块供电，报警模块按照报警信号进行报警。
监控控制器持续获取主控制器发送的心跳信号，当心跳信号异常时，例如不能按照预设时间和频率收到主控制器的心跳信号，或者心跳信号中的数据包异常，表示主控制器出现影响注射泵运行的预设故障，须立即停止注射泵运行。
预设故障包括导致主控制器无法继续工作的故障，例如，主控制器内部电路短路、主控制器线路故障等。
监控控制器与主控制器连接之外，还连接注射泵的电机、供电电源、临时电源和报警模块，其中报警模块包括声音报警模块和灯光报警模块，供电电源为外接电源。
监控控制器确定主控制器出现预设故障时，及时切断注射泵的供电电源的供电，并发出报警信号，切断供电电源的供电可触发应急临时电源启动对报警模块供电，报警模块按照报警信号进行报警。
本实施例中，通过在注射泵控制系统设置双控制器，其中主控制器用于向监控控制单元发送通信信号，以及，控制数据采集单元采集注射泵的运行数据，并根据该运行数据判断该注射泵运行是否正常，若出现异常则控制所述报警模块进行报警，单独维护注射泵的正常工作状态，监控控制器用于通过与主控制器的通信信号，监控主控制器是否出现故障，若出现故障则切断供电电源对注射泵的供电，触发应急临时电源启动为报警模块供电，同时控制报警模块报警，防止单个控制器的控制系统因控制器的故障，造成整个控制泵系统无法应对，不能及时报警从而造成注射泵系统的进一步损害的可能性，实现在主控制器出现故障后及时断电并报警，提高应对故障的效率，以及提高注射泵操作的安全性。
参见图6，图6为本发明另一实施例提供的注射泵控制系统的控制方法的流程示意图。该注射泵控制系统的控制方法可应用于该注射泵控制系统，该方法包括：

进一步地，当检测到注射泵的主设备控制线接入到射频主机时，主控制器控制注射泵的输入设备停止响应输入操作，并执行射频主机发出的指令。当主控制器检测到注射泵的主设备控制线接入到射频主机时，控制注射泵进入从设备模式，即，控制注射泵包括键盘、鼠标、触控屏等在内的输入设备停止响应输入操作，所有的操作指令均由作为主设备的射频主机上输入，注射泵由射频主机侧的操作指令控制。射频主机具体可为消融仪。
进一步地，当检测到静音按键被按下时，主控制器检测当前输出的声音信号，并对应切断声音信号的输出。例如在报警模块进行声光报警时，检测到静音按键被按下，则禁止该报警模块输出声音信号。
