The invention discloses a device and a method for controlling a sliding door of an air conditioner. The device is characterized in that: a transmitting end and a receiving end of an optoelectronic switch are arranged on the two sides of a connecting rod of the sliding door; the upper end and the lower end of the connecting rod of the sliding door are provided with two light leakage holes; the positions of the light leakage holes correspond to the position of the optoelectronic switch; when the connecting rod of the sliding door moves upwards and the top end of the connecting rod props againstan upper sliding baffle block, emitted light of the optoelectronic switch is illuminated on the receiving end of the optoelectronic switch through a lower light leakage hole; and when the connecting rod of the sliding door moves downwards and the bottom end of the connecting rod props against a lower sliding baffle block, the emitted light of the optoelectronic switch is illuminated on the receiving end of the optoelectronic switch through an upper light leakage hole. The device is simple in structure and reasonable in design and saves the cost, and the method is simple in operation, can accurately determine the position state of the sliding door and ensure the normal opening and closing of the sliding door.

The invention provides a method for controlling a sliding door, which comprises the following steps: S1, judging the state of the sliding door by a limit switch; entering step S11 when the door is completely closed; entering step S2 when the sliding door is completely opened or semi-closed; S11, maintaining complete close of the sliding door; S2, judging whether a start-up command exists or not after the initial state of the sliding door is maintained in first preset time, entering step S21 if no start-up command exists, and entering step S22 if the start-up command exists; S21,entering S211 after the sliding door is driven to be completely closed; S211, stopping operation of a driving device, after a complete closed limit switch is closed in second preset time; S22, judging whether the sliding door is completely opened or not, if so, operating an air conditioner, if not, entering step S222; S222, driving the sliding door to be completely opened, then closing a complete opening limit switch in third preset time, and stopping operation of the driving device. Therefore, the opening or closing state of the sliding door can be judged accurately to ensure that the sliding door can be normally opened and closed.

The invention discloses a measuring instrument for building constriction surveying and mapping in multiple environments. The measuring instrument for building constriction surveying and mapping in themultiple environments structurally comprises a surveying and mapping instrument, a positioning supporting disc, three foot stools, foot supports and fixed frames, the surveying and mapping instrumentis fixed to the upper end position of the positioning supporting disc, the three foot stools are in an equilateral triangle shape and distributed and fixed to the lower end position of the positioning supporting disc, the foot supports are arranged at the lower ends of the foot stools, and the foot stools are connected mutually through the fixed frames. According to the measuring instrument for building constriction surveying and mapping in the multiple environments, the foot supports arranged on the foot stools can be rotated and folded up and down, the foot supports are bent downwards whenfacing the cement ground, the ground is supported by the foot supports, the iron pickaxe tail ends of the foot stools are isolated from the cement ground so as to protect an iron pickaxe from being worn due to contact with the cement ground and face the oblique ground by adjusting the length of a middle shaft rod, it is ensured that the opening and closing degree of the foot stools always improvesthe measuring precision through the supporting of the fixed frames, when the iron pickaxe faces soil sandy ground, a material discharging groove adopting a thread shape is formed in the iron pickaxe,soil sand can be discharged through the material discharging groove when being inserted into the soil sandy ground, and the iron pickaxe is more conveniently inserted into the ground.
