A medical testing device

Abstract

The invention discloses a medical testing device, which includes a main control unit, a controlled unit and an execution terminal; the main control unit communicates with a plurality of controlled units through a CAN bus, and each controlled unit communicates with one or more execution terminals. Terminal communication connection; wherein, each controlled unit and execution terminal have an identification number; the information transmitted between the main control unit and the controlled unit is encapsulated into one or more frames according to a fixed format, wherein, in each frame At least the identification numbers of the controlled unit and the execution terminal involved in the frame data are recorded. When the controlled unit obtains the information sent by the master control unit from the CAN bus, it only receives and executes the frame recorded with the corresponding identification number of the controlled unit. The medical inspection equipment provided by the present invention realizes the mutual mapping relationship between the device connection and the identification number, thereby realizing that by modifying the configuration file of the identification number, it can adapt to changes in the increase or decrease of the controlled device or the adjustment of the device connection position, reflecting the Better scalability and versatility.

Description

technical field [0001] The invention relates to a medical testing device. Background technique [0002] The functions of medical testing equipment usually require the cooperation of many hardware devices to complete. For example, the blood sample collection and measurement process involves many processing links such as sample loading, sample suction, flow control, pressure monitoring, cleaning of the outer wall of the sampling needle, and cleaning of the flow chamber. It is realized by the control of hardware devices such as devices and optocoupler status and modulus query. In the inspection equipment, there are many types of hardware devices, and the increase or decrease of hardware devices and the adjustment of control parameters will be involved in the process of equipment development and in product upgrades or configuration changes. These changes often involve the modification of software and hardware, resulting in maintenance and development. higher cost. [0003] In...

Problems solved by technology

[0004] In fact, in the hardware control of medical equipment, although the business-related hardware control logic is complex, the action control of the device itself is relatively limited.

In such a device control scenario, the standard application protocols of the CAN bus are too large and complicated to be developed and implemented
