Abstract

<P>PROBLEM TO BE SOLVED: To solve problems wherein an interface unit is required for transmission to a control device from an air conditioner, an external remote control device and an emergency stop device such as a fire alarm, and a bus is occupied when the external remote control device starts transmission because each data transmission timing depends on the control device, which impedes the timely transmission of data of the emergency stop device of high priority. <P>SOLUTION: This interface unit comprises first to third transceiving device parts 6a-6c transmitting and receiving data of the air conditioner 5, the emergency stop device 4 such as the fire alarm, and the external remote control device 14, and a detecting means for detecting a priority level from data received from each equipment. The third transceiving device part 6c transmits data received from each equipment, to the control device, manages priority order to stop data transmission when receiving data from the equipment of high priority, and transmits information on each equipment to the control device 3 for every priority level of the air conditioner, the external remote control device and the emergency stop device such as the fire alarm. <P>COPYRIGHT: (C)2008,JPO&INPIT

The 2nd transmission / reception device part 6b receives the air conditioner priority order code data of the air conditioner 5 on the transmission line 2c. The first transmitting / receiving device unit 6c receives the priority order code data of the external remote control device 14 on the transmission path 2d. The first memory means 8 comprises means for temporarily storing the received priority code data of the air conditioner 5. The second memory means 9 comprises means for temporarily storing the received priority code data of the external remote control device 14.

  The priority level determining means 7 is connected to the air conditioner 5 and the external remote control device 14 connected from the priority level and the number of priority code data temporarily stored in the first memory means 8 and the second memory means 9, respectively. Of the air conditioner 5 and the external remote control device 14 temporarily stored in the third transmitting / receiving device section 6a at the first memory means 8 and the second memory means 9 at that timing. The interrupt command data is transmitted so as to be transmitted.

  Next, the operation of the interface unit of the present embodiment configured as described above will be described.

  First, in response to a data request command transmitted from the control device 3 at regular intervals, the third transmission / reception device 6a transmits data to the control device 3 from the emergency stop device 4 such as a fire alarm. The first memory means 8 starts the temporary storage of the external remote control device data received by the first transmission / reception device section 6d, and the second memory means 9 starts the air conditioner received by the second transmission / reception device section 6b.

  The priority level determination means 7 monitors the reception priority codes of the first memory means 8 and the second memory means 9, and counts the priority code level and the number of the priority code. The priority level can be set in 16 levels (0 to F) (assuming that priority level 4 of the air conditioner 5 and priority level 3 of the external remote control device 14), and a data table (number × number). Priority level) determines the number of transmissions per minute, and the priority level determination means 7 sends interrupt command data for requesting switching of transmission data to the third transmitting / receiving device unit 6a at equal intervals per minute from the number of transmissions.
