Abstract: Disclosed is a method for cancelling an insurance policy that includes: detecting whether a preset cancellation condition of an insurance policy is satisfied when the insurance policy is under an insurance-applying status or under a to-be-underwritten status; acquiring a corresponding cancellation period of the insurance policy if the preset cancellation condition of the insurance policy is satisfied; detecting within the cancellation period whether a first change instruction is received which first change instruction is intended to change the status of the insurance policy so that the preset cancellation condition of the insurance policy is no longer satisfied; and cancelling the insurance policy when the first change instruction is not detected. Further disclosed are a device for cancelling an insurance policy, an insurance system, and a computer-readable storage media.

Abstract: The present application discloses a method for allocating processing task of insurance service, a computer readable storage medium, a terminal device and an apparatus. This method comprises: determining a processing task to be allocated and an insurance service corresponding to the processing task; acquiring an evaluation factor of the insurance service; determining a processing authority level required by the processing task according to the acquired evaluation factor; determining institution authority levels of various insurance institutions according to the acquired evaluation factor and preset institution factors of the various insurance institutions; determining a first insurance institution entitled to handle the processing task according to the processing authority level and the institution authority levels; and allocating the processing task to the first insurance institution according to a preset allocation rule.

Abstract: A method for controlling a multi-split air conditioner. The method comprises: detecting whether the degree of superheat of an outdoor unit meets a target requirement, if yes, determining whether a difference value between an average exhaust temperature of the outdoor unit and the average exhaust temperature of an outdoor unit system reaches a preset value, if yes, comparing the average exhaust temperature of the outdoor unit with the average exhaust temperature of the outdoor unit system, reducing operating frequency of a compressor of the outdoor unit if the average exhaust temperature of the outdoor unit is greater than the average exhaust temperature of the outdoor unit system; and increasing the operating frequency of the compressor of the outdoor unit if the average exhaust temperature of the outdoor unit is less than the average exhaust temperature of the outdoor unit system.
