2. The system of claim 1, wherein the syringe pump control system further comprises: a control switch;
the monitoring controller is connected with the control switch, and when the control switch is switched on, the monitoring controller starts the power supply to supply power.
3. The system of claim 1 or 2, wherein the supervisory controller is further connected to a stepper motor module of the syringe pump;
and the monitoring controller is used for controlling the stepping motor module to stop working when the communication signal is abnormal.
4. The system of claim 3, wherein the master controller is further interfaced with a master device of the syringe pump;
and the main controller is used for controlling the input equipment of the injection pump to stop responding to input operation and enter a slave equipment mode when detecting that the interface of the main equipment is connected to the radio frequency host.
5. The system of claim 4, wherein the main controller is further connected to a mute switch of the syringe pump, and the output of the sound signal is turned off when the mute switch is turned on.
6. A control method of an injection pump control system, comprising:
acquiring a communication signal transmitted by a main controller in an injection pump control system;
when the communication signal is abnormal, determining that a preset fault occurs in the main controller;
and cutting off a power supply of the injection pump, triggering a temporary power supply to start to supply power to an alarm module, and controlling the alarm module to alarm.
7. The method of claim 6, wherein said powering down the syringe pump comprises, prior to:
and controlling a stepping motor module of the injection pump to stop working.
8. A control method of an injection pump control system is characterized in that,
sending a communication signal to a monitoring controller in an injection pump control system, so that the monitoring controller determines that a preset fault occurs in the main controller when the communication signal is abnormal;
continuously collecting working state data of the injection pump;
and when the abnormal situation of the injection pump is judged according to the working state data, controlling an alarm module of the injection pump to alarm.
9. The method of claim 8, further comprising:
when the slave device control line of the injection pump is detected to be connected to the radio frequency host, the input device for controlling the injection pump stops responding to input operation and enters a slave device mode.
10. The method of claim 9, further comprising:
when the alarm module performs sound-light alarm, if the mute key is detected to be pressed, the alarm module is prohibited from outputting sound signals.
