Problems solved by technology

[0003] The above control method needs to use a large number of pins of the control chip, that is, each switching device needs to occupy a pin of the control chip, which is too resource-intensive
For complex instruments, there are hundreds of valves at every turn, so the requirements for the controller are very high and the cost is high
Moreover, the configuration is not flexible enough. When the number of switching devices needs to be expanded, the board can only be redone. The development cost is high, and it is difficult to meet the application under different quantity requirements.

Embodiment 1

[0069] In this embodiment, the drive board 20 is mainly used to drive the switching type of the actuator. The actuators in the sample analyzer include but are not limited to the above-mentioned ones. In this embodiment, the drive board 20 is used to drive valves, pumps, etc. , Heating rods, Peltiers, relays, electromagnets, fans and other types of actuators are described as examples. The data input end of the first driving board is connected to the data output end of the main controller 110; the data output end of each driving board 20 is used to connect to the data input end of the next driving board to realize serial connection. The driving board 20 has one or more driving terminals, and this embodiment is described by taking multiple driving terminals as an example. At least one driving end of the driving board 20 is connected to the actuator, and usually except the last one, the driving ends of the front driving board 20 are all connected to the actuator.

Embodiment 2

[0086] In this embodiment, the driving board 20 is mainly used to drive the executing device and the collecting device of the signal collecting system. Such as Figure 9 and Figure 10 As shown, the driver board 20 of this embodiment is provided with a first communication interface 210 , a second communication interface 220 and a sub-controller 230 . The sub-controller 230 of the first driver board communicates bidirectionally with the main controller 110 through the first communication interface 210, and the sub-controllers 230 of other driver boards communicate with the previous driver board 20 bidirectionally through the first communication interface 210. The sub-controller 230 communicates bidirectionally with the next driver board 20 through the second communication interface 220 . The sub-controller 230 is connected to at least one executing device and at least one collecting device.

[0087] Further, one or more driving circuits 240 and one or more receiving circuits...

Abstract

The invention provides a sample analyzer and a control system thereof. The control system comprises a main controller and a plurality of driving boards connected in series; the driving boards and the main controller are connected in series to form a serial communication structure of a bus topology; the data input end of the first driving board is connected with the data output end of the main controller; the data output end of each driving board is used for being connected with the data input end of the next driving board so as to realize series connection; each driving board is provided with one or more driving ends, and at least one driving end on each driving board is connected with an execution device; and the driving boards are used for driving the execution devices connected with the driving ends. Due to the fact that the driving boards are connected with the main controller in series, when the number of the execution devices needs to be increased, the driving boards are continuously connected in series, expansion is flexible, the number of pins of the main controller does not need to be depended on, the main control board does not need to be remade, and cost is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sample analyzer and a control system thereof. Background technique [0002] Such as figure 1 As shown, the blood cell analyzer is mainly composed of a control system 1', a sampling system 2', a reagent supply system 4', a reaction system 3' and a signal acquisition system 5'. The sampling system 2' is mainly responsible for collecting blood samples into each reaction pool, the reagent supply system 4' is responsible for adding different reaction reagents into the reaction pools, the reaction system 3' is responsible for providing the reaction environment, and the signal acquisition system 5' completes the reaction process Processing and acquisition of various signals. These processes are accompanied by the control of a large number of valves, pumps, heating rods, electromagnets, fans and other power switching devices. The existing control method for switching devices is gene...
