The invention provides wearable equipment, a watchband mechanism and a watch head mechanism, the wearable equipment comprises the watch head mechanism and the watchband mechanism, and the watchband mechanism comprises a watchband assembly and an air bag assembly; the meter head mechanism is provided with an assembling surface in the thickness direction, an assembling groove is formed in the assembling surface, and the meter head mechanism is further configured to be used for controlling the air bag assembly to expand or contract; the watchband assembly is arranged in the assembling groove from the assembling surface and is detachably connected with the watch head mechanism; the air bag assembly is arranged on the watchband assembly and is communicated with the watch head mechanism after being installed in the assembling groove along with the watchband assembly. Through the arrangement, the communication between the air bag assembly and the watch head mechanism can be fixed by utilizing the detachable connection between the watchband assembly and the watch head mechanism, so that a structure for fixing the air bag assembly on the watch head mechanism is omitted, and the available space of the watch head mechanism is increased; and limitation is brought to the modeling design of the header mechanism and the layout of internal devices due to insufficient space.

The invention discloses a control method and control system of a rail transit door system, the rail transit door system comprises two-out-of-two processing channels, the two processing channels are provided with independent motor control circuits, and the motor control circuits are used for controlling an execution mechanism to conduct door opening and closing operation; when the two-out-of-two voting fails, the first processing channel is selected to output a control signal of the execution mechanism, and the second processing channel is shut down and guided to the safe side; when any processing channel breaks down, the processing channel is shut down and guided to the safe side, and the other processing channel does not carry out two-out-of-two voting and directly outputs a control signal. According to the method, operation can be continuously maintained when any processing channel fails, the safety integrity level of related safety functions is reduced to SIL2 from SIL4, and the usability of a vehicle door control system and a platform door control system is greatly improved under the condition that basic safety requirements are ensured. And meanwhile, the problem that the SIL4 vehicle door control system and the platform door control system cannot be closed due to shutdown guiding to the safe side under the abnormal condition can be avoided.
