In this embodiment, each power supply module includes one power isolation module 114, and the number of the power isolation modules 114 corresponds to the number of the power supply modules 104. When there are a plurality of power supply modules, the number of power isolation modules 114 is also a plurality. Each power isolation module 114 outputs an independent power supply to supply power to a corresponding one of the sensors, so that the power supply modules respectively supplying power to the multiple sensors are independent at the output ends and do not interfere with each other. According to the embodiment, the independent power supply provides the working bridge supply voltage for each sensor, the signal interference possibly existing in the bridge supply shared by a plurality of sensors is avoided, and the accuracy and the integrity of data acquisition of the sensors are improved.
Specifically, in this embodiment, the input ends of the power isolation modules 114 are connected in parallel to the same external power source, so that the input ends of the power supply modules are connected in parallel to the same external power source, and the output ends of the power isolation modules 114 are independently arranged, so that the output ends of the power supply modules are independently arranged, and the output end of one power isolation module outputs one independent power source, so as to independently supply power to the corresponding one of the sensors and the corresponding one of the data acquisition modules. In other words, an external power supply provides a plurality of mutually isolated independent power supplies in a physical isolation mode, the output ends of the mutually isolated independent power supplies are mutually independent and do not interfere with each other, and each independent power supply independently supplies power for a corresponding path of sensor and a corresponding data acquisition module.

The comparator 134 and the current-spreading transistor provide a stable supply bridge voltage for the sensor according to the supply bridge reference voltage outputted by the voltage reference module 124.
In this embodiment, since the voltage reference module 124 has precise initial accuracy, extremely low noise, and the bridge reference voltage outputted during temperature and time variation can be kept stable and unchanged, thus, an absolute regulated voltage is provided by the voltage reference block 124, and the absolute regulated voltage is compared to the output voltage of the isolated power supply by the comparator 134, resulting in a feedback signal for regulating the supply bridge voltage, the switching time of the current-expanding triode 144 is adjusted by the feedback signal, finally a bridge supply voltage with strong loading capacity and very stable voltage is obtained, thereby ensuring that the voltage of the supply bridge is not misaligned or fluctuated, avoiding the serious influence on the sensor, and then guaranteed to use this data acquisition device to carry out the rail weighbridge normal work that measures the weighing to the train load, realized the effective measurement to the load of train.
In this embodiment, the structure of the voltage reference module 124 is not particularly limited as long as the power supply reference voltage can be generated.
