Embodiment:
See also Figure 1 and Figure 2, be three-dimensional appearance schematic diagram of the present utility model, block schematic diagram of the present utility model.As shown in the figure: the intercom of a kind of tool power frequency of the utility model carrier wave, its by the intercom more than one 1, a signal indicating device 2, and an indoor power line 3 constituted, can make each intercom 1 utilize this indoor power line 3 to reach the bi-directional of signal data.
Above-mentioned each intercom 1 of carrying includes a single-chip control module 11, one transmission rate is a power carrier module 12 and the outside output module 13 of 1200BPS, wherein this single-chip control module 11 is by an input receiving element 111, one output control unit 112, one control unit 1 13, one communication interface 114 and a relay 115 constitute, and this control unit 113 is one to have 8051 single-chips of excellent internal structure as processing unit, operating frequency can reach 16MHz, but read-only memory (Read Only Memory with the burning of 4K electrical equipment and removing, ROM), and 8 groups of inputs and 8 groups of outputs are provided, and utilize these relay 115 buffer circuits to guarantee and to control the safe operation of this single-chip control module 11 respectively at this output.The communication interface 114 of one group of full duplex is contained in the inside of this 8051 single-chip, this communication interface 114 can be the RS232 interface, can transmit or receive the data that the outside is sent here simultaneously, because its actuating signal all is that (logical zero is 0V in TTL standard position, logical one is+5V), this communication interface 114 is a serial communication, with a series of bit patterns data is transmitted or receives, and makes controller (as: receiving position formula Carrier or auto-measuring instrument), equipment or intercomputer can set up online easily.
This signal indicating device 2 is connected with above-mentioned single-chip control module 11, and in order to showing the operating state of above-mentioned intercom 1, and this signal indicating device 2 is a phonation unit, or the phonation unit screen of arranging in pairs or groups.
This indoor power line 3 connects the outside output module 13 of above-mentioned each intercom 1, and in order to as the providing of power frequency carrier wave, this indoor power line 3 is general indoor power supply.In this way, constitute the intercom of a brand-new tool power frequency carrier wave by above-mentioned arrangement.
