Capacitor and capacitor communication device

The utility model relates to the field of capacitors, discloses a capacitor and a capacitor communication device, and provides a capacitor communication device in order to solve the problem that in the prior art, cost is wasted due to the fact that a new capacitor is needed for achieving communication between the capacitor and an intelligent fusion terminal. The device is connected with a capacitor through a signal sampling circuit, can collect relevant parameters of operation of the capacitor, the parameters are input to a processor after passing through an A/D converter, and the processor sends signals collected by the signal sampling circuit to an intelligent fusion terminal through a communication interface circuit to achieve communication. Related parameters of the capacitor can be uploaded without replacing the capacitor, the processor is connected with the output circuit so as to confirm output of the output circuit according to signals collected by the signal sampling circuit or signals sent by the in
