1. A smart window, comprising a glass module, a first controller, at least one light bar group and a light bar monitoring circuit; wherein
the glass module is coupled to the first controller, and light transmittance of the glass module is controlled by the first controller;
the at least one light bar group is coupled to the first controller and emits light under control of the first controller to indicate an operating state of the glass module; and
the light bar monitoring circuit comprises at least one light bar monitoring sub-circuit; the at least one light bar monitoring sub-circuit is coupled to the first controller and is coupled in a one-to-one correspondence to the at least one light bar group, so as to detect the operating state of the light bar group coupled to the at least one light bar monitoring sub-circuit and feed the operating state back to the first controller;
the smart window further comprises at least one light bar driving circuit which is coupled to the first controller and is coupled in a one-to-one correspondence to the at least one light bar group, wherein
each of the at least one light bar group comprises a display light bar and at least one backup light bar, and both the display light bar and the at least one backup light bar in each of the at least one light bar group are coupled to a corresponding light bar driving circuit; and
the first controller receives the operating state of the display light bar sent by the at least one light bar monitoring sub-circuit, and controls the corresponding light bar driving circuit to stop driving the display light bar and to drive one of the at least one backup light bar when the operating state of the display light bar is abnormal.
