Abstract

DC60 (18/10/47) A communication device for an elector including a two electoral communication network. The network is the least. In which the data is communicated with different protocols and network protocol converters that are connected between them. The network protocol converter will Including dual port memory For simple data transfers And the memory register to take Transfer priority data with shorter intermittent read / write processes and chain controllers. Network that is organized in each communication network. This is used to select dual port and unit memory. Any one of the register memory For ordinary data transfers And transfer priority data where the least necessary information Will be transferred in order of importance Through the memory register, protocol conversion and data transfer can be performed with minimal interference to the network controller's processing. And delay in transferring data, it can Can be minimized Communication equipment for the elevators, including the two Eleven communication networks. The network is the least. In which the data is communicated with different protocols and network protocol converters that are connected between them. The network protocol converter will Including dual port memory For simple data transfers And the memory register to take Transfer priority data with shorter intermittent read / write processes and chain controllers. Network that is organized in each communication network. For selecting dual port and unit memory Any one of the register memory For ordinary data transfers And transfer priority data where the least necessary information Will be transferred in order of importance Through the memory register, protocol conversion and data transfer can be performed with minimal interference to the network controller's processing. And delay in transferring data, it can Can be minimized

Claims (8)

1. A communication device for an elevator, including a network protocol converter that is connected between two electoral communication networks. The network is the least. In which the data is communicated through different protocols. Dual port memory for conventional data transfer and a register memory for priority transfer with shorter interruptions than the dual port memory. 2.Communication equipment for the Elevator Which at least consists of At least two elector communication networks. In which information will be communicated Through a different protocol and a network protocol converter that is connected between them, the converter The network protocol includes Dual port memory for simple data transfer Memory registers for priority data transfer with shorter intermittent read / write processes than the dual port memory and the network controller on each such communication network to select Dual port memory and One of the memory registers for simple data transfer and data transfer. Priority 3. Communication equipment for the elector as described in Clause 2, where the controller The network includes a memory that holds each read / write cycle of the dual port memory. And memory Such register And priority information Method for setting read / write cycles And the priority data stored in the said memory, and the network data transfer control pathway for conventional data transfer through the unit.
