Description

Smart Caster

The invention relates to a smart caster.

Generally, the wheel frame or bed for placing expensive instruments is often moved to different places such as hospital wards, operating rooms or laboratories. In order to effectively track the position to avoid the loss of the above wheel frame or bed, it will be placed on the wheel frame or the bed. A GPS module is set on the bed of the hospital bed, and the GPS signal is wirelessly transmitted to the satellite or the control center by the GPS module, and the tracking function can be achieved to avoid the loss of samples or instruments.

However, when using some precision instruments, it is necessary to avoid placing wireless communication equipment in the surroundings to avoid interfering with the accuracy of the instrument. Therefore, setting a GPS module on the wheel frame or the bed of the bed will cause the GPS module and the instrument to interfere with each other, resulting in It will not be able to effectively transmit GPS signals for tracking the location, but it will also affect the accuracy of the instrument. In addition, after the battery of the GPS module is exhausted for a period of time, the battery needs to be replaced before the power can continue to provide the GPS module to operate. If you accidentally forget to replace the battery, when the battery of the GPS module is exhausted, you will not be able to smoothly Tracking the position of the GPS module has the disadvantages of urgent improvement.

Therefore, it is necessary to provide a novel and progressive intelligent caster to solve the above problems.
