TM80 Telemetry Monitor Service Manual 4-1
4 Product Principles
4.1 System Composition
The TM80 consists of dedicated functional modules (MPAN module and Wi-Fi
module), parameter front-end processing module, main control processor module
and power module.
Dedicated functional modules: include the Wi-Fi module and MPAN module. The
MPAN module is managed and controlled by the parameter front-end processor and
the Wi-Fi module is managed by the main control processor.
Parameter front-end processing module: The module is the core of the whole
system and realizes parameter collection and communication control. The modules
completes ECG parameter sampling, obtains SpO2 parameter data, controls the
MPAN module in completing communication with the NIBP module, packs
parameter data and transmits it to the main control processor over protocol. It is
also responsible for power management and key (power on/off key and nurse
calling key) detection.
Main control processor: The main control processor realizes exchanging
physiological parameter data with the front-end processor in real time, local
parameter algorithm, data forwarding (transmission to the CMS over Wi-Fi) and
collaboratively completes system power control with the parameter front-end. In
addition, it drives the LCD display and touch screen, displays parameter waveforms
and values in real time, and realizes man-machine interactive operation.
