Abstract: A traceable method for the blockchain data is disclosed. A regulator generates the public parameters pp. Each user generates his own registration information and sends it to the regulator. The regulator verifies the registration information of each user, and makes some information public. When the data in the blockchain application needs the public information and identity proofs of the users who indirectly participate in data creation, each user in Acreate obtains the identity proofs of the users in Bother; each user in Acreate creates his own identity proof, then generates the data datatrace=[{proofid}id?I, databody]crytool and sends it to the node network. The node network verifies the received user data and adds it to the block. The regulator then obtains data from the blockchain and decrypts the ciphertexts in the data to determine the identity set corresponding to each data.

Abstract: Provided is a compressor over-load protection control method. The method includes that: the state of a compressor is detected (S101); it is judged whether the compressor is under over-load protection (S102); and when the compressor is under the over-load protection, fluorine shortage protection is shielded (S103). A compressor over-load protection control apparatus includes: a detection unit (10), configured to detect the state of a compressor; a judgement unit (20), configured to judge whether the compressor is under over-load protection; and a shielding unit (30), configured to shield fluorine shortage protection when the compressor is under the over-load protection. Through the method and apparatus, the problem in the relevant art that a fluorine shortage false alarm is easily triggered is solved, thereby achieving the effect of preventing the fluorine shortage false alarm when the compressor is under the over-load protection.

Abstract: A method and a system for monitoring an abnormality at an air outlet of a dehumidifier. The method comprises: identifying whether there is a blockage abnormality at the air outlet of the dehumidifier; after a blockage abnormality has been identified, starting a high wind-level operation of the dehumidifier or controlling air deflectors of the dehumidifier to be reset; after the high wind-level operation has run for a set time period or after the air deflectors are reset, identifying whether the blockage abnormality has been eliminated; and after it has been identified that the blockage abnormality has not been eliminated, controlling the dehumidifier to stop running, and sending out a fault cue. The method and system disclosed can avoid influences on the operation, service life and reliability of the dehumidifier due to a long-term blockage at the air outlet of the dehumidifier.

Abstract: The disclosure discloses a refrigerant control method for a dehumidifier. The method includes that: an environment temperature and an evaporator tube temperature of a dehumidifier are detected; according to the environment temperature and the evaporator tube temperature, a refrigerant leakage amount of the dehumidifier is obtained; and according to the refrigerant leakage amount, it is judged whether the dehumidifier has a refrigerant fault. The disclosure also discloses a refrigerant control apparatus for a dehumidifier.

Abstract: The disclosure discloses a compressor over-load protection control method. The method includes that: the state of a compressor is detected (S101); it is judged whether the compressor is under over-load protection (S102); and if the compressor is under the over-load protection, fluorine shortage protection is shielded (S103). A compressor over-load protection control apparatus includes: a detection unit (10), configured to detect the state of a compressor; a judgement unit (20), configured to judge whether the compressor is under over-load protection; and a shielding unit (30), configured to shield fluorine shortage protection if the compressor is under the over-load protection. By means of the method and apparatus, the problem in the relevant art that a fluorine shortage false alarm is easily triggered is solved, thereby achieving the effect of preventing the fluorine shortage false alarm when the compressor is under the over-load protection.

Abstract: The disclosure discloses a dehumidifier control method and apparatus, and a dehumidifier. The control method includes that: an environment temperature parameter and an environment humidity parameter of a dehumidifier are collected; a working condition of the dehumidifier is determined according to the environment temperature parameter and the environment humidity parameter; a running mode corresponding to the working condition is obtained; and the dehumidifier is controlled to work under the running mode. The control method improves the stability of the dehumidifier.
