In one embodiment, the substrate control system further comprises: a first switch assembly SV2, a liquid suction driving unit Z, a second switch assembly SV3, a switching device SV4 and a plurality of substrate needles which are connected in sequence; one end of a switching assembly SV1 is connected with the output pipelines 32 of a plurality of liquid suction assemblies 3, a first switch assembly SV2 is connected with the other end of a switching assembly SV1, a liquid suction driving unit Z is respectively connected with a first switch assembly SV2 and a second switch assembly SV3, and a switching device SV4 is connected with a plurality of substrate needles;

the control unit is also used for controlling the imbibing driving unit Z to move reversely and push the substrate liquid which is currently imbibed by the imbibing component 3 back to the current substrate container 2 after receiving the alarm signal generated by the processing unit and before generating a switching signal.
In this embodiment, the first switch module SV2 and the second switch module SV3 may be any switch valves capable of controlling the on/off of the lines, the pipetting driving unit Z may be a substrate injector, the switching device SV4 may be any switching valve capable of controlling the switching of the lines, and the substrate needle is used for pouring out the substrate liquid.
The following is a specific scenario: in a certain detection, 200ul of reaction substrate liquid needs to be filled, the liquid suction driving unit Z has a capacity of 500ul, the liquid suction assembly 3 is provided with two liquid suction assemblies which respectively correspond to a substrate container F1 and a substrate container F2(F1 and F2 are the substrate containers 2 in the substrate device), the detection assembly 4 can comprise a detection unit Q1 and a detection unit Q2(Q1 and Q2 are the bubble sensors 42 in the substrate device) which are arranged in the two liquid suction assemblies 3, the detection assembly 4 can be one detection unit or can realize the bubble detection of a plurality of liquid suction assemblies 3 when the detection assembly 4 is arranged at the output end positions of the two liquid suction assemblies 3, and the substrate needles are provided with two, namely the substrate needle DD1 and the substrate needle DD 2.
The present scenario will be further explained by taking in the substrate liquid in the substrate container F1 and injecting the liquid into the substrate needle DD 1:

When the detection unit Q1 detects bubbles and the processing unit sends an alarm signal, the liquid suction is still continuously performed, but the liquid suction driving unit Z is controlled to move reversely after the liquid suction is finished, the sucked substrate liquid is pushed back to the substrate container F1, and meanwhile, the pushed substrate pipeline is still filled with the substrate liquid, so that the whole pipeline does not need to be filled when the next replacement is carried out, the maintenance burden of users and service personnel is reduced, and the cost of filling the substrate liquid is also reduced; the switch assembly SV1 is then controlled by the control system to disconnect from the current pipetting assembly 3 and switch assembly SV1 is connected to the other pipetting assembly 3, i.e. when the other pipetting assembly 3 and substrate container F2 are activated.
The detection principle of the detection unit Q1 in this specific scenario is as follows: the detection unit Q1 detects the bubble value of the substrate liquid in the output pipeline 32 when the substrate liquid is sucked by the front liquid suction assembly 3 and sends the bubble value of the substrate liquid to the processing unit, the processing unit compares the received bubble value of the substrate liquid with a preset bubble threshold value, and if the bubble value of the substrate liquid exceeds the bubble threshold value, an alarm signal is generated and sent to the control system.

the imbibition driving unit is used for controlling the current imbibition assembly to aspirate or push back the substrate liquid from the corresponding substrate container and injecting the substrate liquid into the current substrate needle;
the control unit is also used for controlling the imbibing driving unit to move reversely and pushing the substrate liquid which is currently imbibed by the imbibing component back to the current substrate container after receiving the alarm signal generated by the processing unit and before generating a switching signal.
10. The substrate control system of claim 8, wherein the detection assembly comprises a detection unit for detecting a plurality of pipetting assemblies; the detection unit is used for detecting the substrate liquid bubble value in an output pipeline of the liquid suction assembly when the liquid suction assembly sucks the substrate liquid and sending the substrate liquid bubble value to the processing unit.
