Abstract

Abstract A control system for the monitoring and control of equipment composed of electrical devices (1, 2, 3), in which system is included a host computer (10) while each electrical equipment is furnished with a slave computer (11, 12, 13). the intention being to bring into use a simpler and in particular a more easily installed control system than heretofore. In accordance with the invention the host computer (10) and the slave computers (11, 12, 13) are interfaced with one another so that the data channel (14) runs from the host computer to the first slave computer, from there to the second slave computer, from there on to the following and so on, to each computer through the preceding machine, when each slave computer is arranged to process the control signals given to it and to the following slave computers by the host computer and to give to the following slave computer the control signals intended for it and for following slave computers.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 164 words
A control system for monitoring and controlling equipment made up of electrical devices (1, 2, 3), to which system belongs a host computer (10) and each electrical device being mainly furnished with a slave computer (11, 1 2 , 13) the slave computers being organised to control the corresponding electrical devices under the control of the host computer characterised in that the host computer (10) and the slave computers (11, 12, 13) are interfaced to each other so that the data path (14) runs from the host computer to the firts slave computer, from this to the second slave computer, and from this again to the following and so on, to each slave computer through the preceding slave computer, whereupon each slave computer is arranged to process the control signals given to it and to the following slave computer by the host computer and to give to the following slave computer and to the slave computer following that the control signals intended for them.
Claim 2
Dependent Claim 164 words
A control system for monitoring and controlling equipment made up of electrical devices (1, 2, 3), to which system belongs a host computer (10) and each electrical device being mainly furnished with a slave computer (11, 1 2 , 13) the slave computers being organised to control the corresponding electrical devices under the control of the host computer characterised in that the host computer (10) and the slave computers (11, 12, 13) are interfaced to each other so that the data path (14) runs from the host computer to the firts slave computer, from this to the second slave computer, and from this again to the following and so on, to each slave computer through the preceding slave computer, whereupon each slave computer is arranged to process the control signals given to it and to the following slave computer by the host computer and to give to the following slave computer and to the slave computer following that the control signals intended for them.
Claim 3
Dependent Claim 47 words
' A control system according to claim 1, characterised in that the control system is arranged to. govern building technology equipment made up of equipment such as electrical heating devices (1, 2, 3) when each heating equipment is mainly furnished with a slave computer (11, 12, 13).
Claim 4
Dependent Claim 42 words
A control system according to claim 2, characterised in that each heating device (1, 2, 3) is furnished with temperature sensor (4, 5, 6) to measure the heating device surface temperature and with temperature sensor (7, 8, 9) to measure room temperature.
Claim 5
Dependent Claim 35 words
A control system according to claim 2 or 3, characterised in that the host computer (10) or at least one slave computer (11) is furnished with an external temperature sensor (15) to measure external temperature.
Claim 6
Dependent Claim 60 words
A control system according to anyone of claims 2-4, characterised in that the system includes a slave heater (23) which is connected to a slave computer (13) by means of the data channel (17) transmission, and that the slave heater is furnished with a temperature sensor (29) measuring the surface temperature of the slave heater connected with the slave computer.
Claim 7
Dependent Claim 65 words
A control system according to anyone of claims 2-5, characterised in that the slave computers (11, 12, 13) are arranged to give signals corresponding to corresponding room temperatures and surface temperatures of the corresponding heating devices (1, 2, 3) to the host computer (10) and that the host computer is arranged to calculate and output the setting values and maximum powers to the slave computers.
Claim 8
Dependent Claim 43 words
A control system according to anyone of claims 2-6, characterised in that the slave computers (11, 12, 13) .are arranged to calculate the total power to be used by the corresponding heating device, and to transmit the corresponding signal to the host computer.
Claim 9
Dependent Claim 66 words
A control system according to anyone of claims 2-7, characterized in that each slave computer (11, 12, 13) is arranged to control independently the corresponding heating device (1, 2, 3) on the basis of the signals received from the corresponding surface temperature sensors (4, 5, 6) and from the corresponding room temperature sensors (7, 8, 9) whereupon contact to the host computer (10) is cut off.
