Abstract

It consists of electronic units 1 connected to the electrical network of a building. Each of the units includes an electronic breaker and is substituted for the current outlet 5 so as to leave only the new telecontrolled outlet 4 visible. A detection circuit converts the parameter(s) to be monitored into an electrical signal which can be exploited by the device. A central computer also connected to this network manages the complete installation while incorporating the various parameters supervised by the electronic units. Each of these units can be linked electronically to another unit via special outlets 10 also situated on these assemblies. The device is particularly intended for the active supervision and monitoring of a building such as: heating supervision, alarm system, access supervision etc.

Description

 The present invention relates to a device giving the electrical network of a building the ability to transfer and analyze data usable by one or more computers also linked to this network.

Technical sector
The use relates to any application having a question / answer type operation and requiring an analysis of data such as
- heating control
- alarm / security
- computer network ...

state of the art
Traditionally, this type of transmission is the subject of additional installations connecting the switchgear to the control processor (example the heating thermostat electrically connected to the radiators)
It requires specialists and involves high installation costs.

Furthermore, these devices are not interactive and often deal with only one parameter at a time.

Example: conventional heating is only regulated by its temperature
while other elements can be taken into account such as - time at which we want to obtain the temperature - time at which the reduced EDF tariff begins - building insulation coefficient - building occupancy period - degree humidity - outdoor temperature ...

The device according to the invention overcomes these drawbacks. It allows centralized control of a building such as temperature, alarms, fire, etc.

 If a problem occurs, - the network computer will act, if necessary, on the element or elements causing the problem. It can incidentally provide the user with functional states of the building - list of the rooms in the building currently heating - deferred programming of the building's heating - humidity level ...

note: the application to heating is only an example and does not constitute the
exclusive field of application of the invention.

In addition to its important economic role, this invention makes it possible to increase the comfort and above all the security of a building. The cost of installation and / or investment remains negligible compared to the service rendered.

This is all the more justified in that in an industrial environment energy consumption and safety are important elements.
The object of the present invention is to define a bi-directional communication device using the electrical network. In FIG. 1, an electronic transmitter-receiver unit (1) is responsible for transmitting the information. It is small, electrically connected and plated on a socket (5) of the building which is now hidden. Only the socket (4) integrated into this removable electronic unit remains accessible. Figure 3 describes these electronic assemblies also called removable units
A transmitter (31) and a receiver (32) ensure the shaping of the electrical signals. A coupling circuit (33> allows connection to the electrical network (37). After recognition of the address of the unit via the circuit decoding (34), the data is sent to the processor (35) which analyzes it. If initiatives are to be taken by the processor (35) the orders will travel the opposite way via the transmitter (31); power supply (36) makes it possible to supply a regulated voltage necessary for the proper functioning of the electronics. A detection circuit (9) has the possibility of receiving several sensors (11) making it possible to monitor several physical elements (temperature, smoke, presence. .

 Starting from a single electronic assembly.

The role of this circuit is to convert one / more physical parameters (example: heat into data usable by electronics (example: voltage). The power part (12) is responsible for switching the socket (45. It acts like a remote controlled switch.

Figure 2 shows an example of use in a building. Several electronic assemblies (1) each grouping together one or more tasks ~ (temperature, presence detection, etc.) interact with a central processor (2 '. The latter has a decision-making role; thus it can isolate a socket outlet according to its programming or generate an action / alarm to the user in the event of failure, withdrawal or deleantle of a removable unit (1). It is particularly assigned to analyze the data coming from the electronic assemblies (1). (8) is mounted at the head of the EDF network in order to isolate the device from disturbances outside the building. Finally to allow control of a group of devices (5), a power assembly (7) can be inserted incidentally at the connection point corresponding to these devices In this application, the temperature is controlled Far the central processor (2) via the removable units (1) located in the rooms containing these devices.

Wota: any imprecise name as "electronic assembly"
uses current technology and is subject to change
in time.

 Each removable unit has the option of being electronically connected to another unit. In this so-called "transparent" mode, its socket (10) can receive or transmit logic signals to another unit. This mode is introduced either by the central processor or by the user via the access keys (3) of the removable unit itself. The central processor as well as the removable units use their own software which will ensure flexibility of use and good management of the device
