Medical examination equipment

Abstract

The invention discloses medical examination equipment. The medical examination equipment comprises a master control unit, controlled units and execution terminals; the master control unit is in communication connection with the controlled units through a CAN bus, and each of the controlled unit is in communication connection with one or more execution terminals; each of the accepted units and each of the execution terminals respectively have an identification number; and information transmitted between the master control unit and the controlled units is packaged according a fixed format to form one or more frames, every frame at least records the identification numbers of the controlled unit and the execution terminal involved in the data of the frame, and when the accepted units acquire information transmitted by the master control unit from the CAN bus, only frames recording the identification numbers corresponding to the accepted units are received and executed. The medical examination equipment realizes mutual mapping relation between device connection and the identification numbers, so the equipment can adapt to increase or decrease of controlled devices or change of the device connection position adjustment by modifying the configuration files of the identification numbers, thereby the equipment has good expansibility and versatility.

Description

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

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
