Force measuring device for anti-seismic vibration testing of building

The invention relates to a force measuring device for anti-seismic vibration testing of a building. The force measuring device comprises an acceleration sensor, a battery arranged around the acceleration sensor, and a circuit module group arranged inside the battery. At least one memory card is connected in the circuit module group detachably. The acceleration sensor is powered by the battery and is used for transmitting a measuring signal and storing the signal into the memory card of the circuit module group. According to the provided force measuring device, because the acceleration sensor, the power supply, and the memory card for storing testing data are combined into one structural component operating independently, cables like a power line and a data line that extend outwardly can be saved, the damages on structure sealing by the cable exits can be avoided, and additional weights are reduced; configuration of expensive multi-path data collection equipment and configuration of an external power adapter are not required; debugging work like impedance matching on the scene is not needed; after data collection, the memory card is removed and then a common card reader is needed, so that lots of money and time can be saved.
