no. 2 example

[0077] Figure 7 It is a structural block diagram of the inter-system interface device 3 of the second embodiment of the present invention, which omits the "operation" function ("operation" from the contention communication system 2 to the polling communication system 1) in the first embodiment formed later.

[0078] Figure 8 is being Figure 7 The front view of the part covered by the door 43 in the second embodiment shown, in the second embodiment, there is no direction selection switch 36, and only the combination switch 15 is installed in the door 43 on the front of the equipment box 40 , work plug 25 and work light 26, such as Figure 8 shown.

[0079] Figure 9 It is an interface device 3 installed between the polling communication system 1 and the contention communication system 2 (such as Figure 7 As shown in the control content explanatory diagram of ), because only the "operation" from the polling communication system 1 to the contention communication system ...

[0082] Figure 10 It is an explanatory diagram of the control content of the inter-system interface device 3 installed between the polling communication system 1 and the contention communication system 2 according to the third embodiment of the present invention.

[0083] Contrary to the second embodiment, the structure of the third embodiment is formed by canceling the "control" function from the polling communication system 1 to the contention communication system 2 in the first embodiment, therefore, in this embodiment and no need to provide figure 1 The direction selector switch 36 in , because only the "control" from the contending communication system 2 to the polling communication system 1 is performed. Figure 5 The function of "switch" in this case, (such as Figure 10 shown) disappeared. Other structures and working elements are the same as the first embodiment.

[0084] Because this structure is specially used to "control" from the polling communication system 1...

no. 4 example

[0086] see Figure 9 , in order to command the "operation" from polling communication system 1 to contention communication system 2, a "single" address of polling communication system is taken, in other words, a switch operation of polling communication system 1 and contention communication system 2, but the polling communication system 1 has the function of controlling a group of loads ("group" control and "mode" control) with a switch, so if the same function is to be used in the nodes of the contention communication system 2 It is also very convenient to realize in the unit 21, that is to say, because the number of valid addresses in the polling communication system 1 is limited, the one-to-one correspondence or mapping between the terminal unit 11 and the node unit 21 can reduce the number of addresses used for polling communication. The number of effective addresses of the terminal units 11 in the system 1 is therefore a structure that allows the addresses of the node uni...

Abstract

In the interface device between the first remote control system of the polling communication system and the second remote control system of the contending communication system, the control section executes at least one of the following processes based on address mapping information, the first control process is based on The transmission signal (the transmission signal representing the reception of the first signal and sent from the first terminal unit) transmits to the second node unit the transmission signal controlling the second load unit, so that the second load unit is controlled according to the first input signal. The second control process is to transmit a transmission signal for controlling the first load to the first load unit according to the transmission signal (the transmission signal represents the reception of the second input signal and is sent from the second node unit), so that the first load is controlled according to the second load signal. load.

Description

technical field [0001] The invention relates to an interface device between two remote control systems having different transmission modes, in particular a first remote control system of a polling communication system and a second remote control system of a contending communication system. Background technique [0002] Generally speaking, the remote control system of the polling system (hereinafter referred to as the polling communication system) that has been proposed has a plurality of terminal units and a set of transmission units, which are connected by a wire, and the transmission unit is executed by accessing the address of each terminal. For data exchange or data transmission and reception between terminal units, the address of each terminal unit is assigned to the corresponding terminal unit by means of time division multiple access. In such a remote control system, in order to control the action of the load in response to the operation of the switch, a pair of termi...
