The best embodiment of the invention

The listed elements are characterized by the following features of the structural diagram and are intended to solve the following problems (as part of the device).

1 - Block of interfaces of external input-output

- it is intended for receiving via an information wire bus and processing telegrams containing commands for changing the state of the device, as well as for sending telegrams containing information on the current state of the device through it. In the basic version, the proposed solution is equipped with a standard RS232 / 485 interface and the ability to change (supplement) plug-in modules of additional interfaces (8). The unit includes an address module that sets the electronic address of the device in the control network.

2. Block of external circuit sensors

- designed to connect any external devices, sensors, buttons, switches, the result of which is the closure of "dry contacts" (state 0-1). s 000030

3. The block pairing the short circuit sensors with power switches has two operating modes:

- first: autonomous operation mode that allows you to control power channels directly, by commands received from circuit sensors, without connecting a control bus;

- second: the mode of operation of the fault sensors through the interface unit, when the state of the fault sensors is read by an external controller, which forms a control action on the power switches that control the loads. 4. Block selection of the operation mode of the circuit sensors:

- provides the opportunity for the user in stand-alone operation mode to select the operation mode of the power switches, depending on the nature of the external command device connected to the circuit circuit of the short circuit sensor. That is, for example, if a button that does not have fixed positions is included as a command device, but it is necessary to fix the state of the output channel after releasing the button, then the “With lock” mode is activated. At the same time, for each button closure, the state of the conjugated output channel changes from “off” to “on” and vice versa. If devices are used that have a built-in position lock, such as household switches, or that require mirroring of state changes, such as motion sensors, fire sensors, reed switches, etc., then the corresponding channel of the switch is set to "No lock" mode.

5. The block of touch buttons - emulators of circuit sensors: - is a series of touch buttons that emulate the work

(providing short circuit) channels of short circuit sensors. Depending on the design of the instrument case, they can be used as control and auxiliary, as well as basic ones. Structurally, the implementation of the touch buttons is the best solution in terms of the price-quality ratio. 6. Block switching keys of power loads:

- The main task of the unit is the control (switching) of external power loads. Depending on the tasks performed, it can be structurally designed to operate both in discrete mode (using, for example, mechanical or electronic relays), and in proportional mode using semiconductor power elements (dimming mode).

7. Unit for indicating the status of the device:

- serves to visually display the status of the device. It can be made both from a set of LED indicators displaying the status of the power supply unit ("Power"), information bus ("BUS"), short circuit sensors and power channels, and using graphical information (text) indicators. 8. Plug-in modules of additional interfaces:

- to universalize the device and quickly adapt it to any other control environment (other than RS485 / 232) without making structural changes to the basic design, the device provides mounting connectors for external interface units of third-party protocols. You can also use radio repeaters of the device’s touch buttons or Ethernet (GPRS) modules as additional modules.

9. Instrument body:

- can be performed both in DIN35 standard and in any other convenient design (for example, as an autonomous touch panel of household switches or as a switching module for aquarium automation, etc.). The main task of a specific design is to provide maximum installation and operating comforts with a maximum aesthetic component at the lowest possible price of the device. AT The composition of the device’s case can include a power supply, which ensures the operation of all elements of the device. It provides the required autonomy of the device, reliable operation, ease of installation and operation.

The device can operate in controlled or manual (autonomous) modes.

Controlled mode.

A telegram containing the address of the device and the command for the corresponding change in its state is received through the information wire bus to the block of interfaces of the external input-output (1). In the block, the address is identified in accordance with the combination specified in the address module. If the address matches, a control signal is generated, which enters the switching key unit (6), setting the state of the power elements specified by the telegram. Plug-in modules of additional interfaces (8) play the role of additional gateways, allowing you to adapt the device to the standards of teams of other manufacturers, thereby expanding the range of its application.

The command received through the block of external closure sensors (2) or from the touch buttons - emulators of closure sensors (5), enters the block of interfaces of the external input-output (1). In accordance with the specified protocol, an electronic telegram is formed, which is sent to the information bus to which the device is connected. This command subsequently enters the external controller available to the consumer — for its subsequent processing and the formation of a control command for changing the states of the output channels of the device. In this case, the command from the block of external short-circuit sensors (2) does not directly enter the block of switching keys (6) and its state remains unchanged. It is also possible to issue telegrams to the information bus with the states of the closure sensors and touch buttons upon request of an external controller. Manual (autonomous) operation mode.

The command received through the block of external short-circuit sensors (2) or from the touch buttons - emulators of short-circuit sensors (5) in accordance with the switch position of the block for interfacing the short-circuit sensors with power switches (3), enters the block for selecting the operating mode of the short-circuit sensors (4). This unit acts as an adapter; it determines what response the channel of the switching key unit (6) will follow to a change in the state of the corresponding short-circuit sensor. Depending on the nature of the work (and the design) of the external device forming the command in the circuit of the short circuit sensor (2), the operation mode “Without latching” or “With latching” is selected. For example, if it is a button that does not have fixed positions, then the “With latch” mode is selected, which switches and fixes the state of the power channel when a “closed - open” command is received. If a switch or a sensor with a fixed position of closed contacts is connected to the input of the closure sensor, or it is not required to fix the state of the output channel with each closure / opening, then the "Without fixation" mode is selected. In this case, the power element will mirror the state of the circuit of the short circuit sensor.

A combined mode of operation of the device is possible, when the power channels are controlled both by telegrams arriving on the information bus, and directly, by commands of the circuit sensors. The way to control a specific power channel is determined by the position of the switches of the interface unit of the short circuit sensors with power switches (3). In this case, in a specific implementation of the device, any options for the conflict resolution logic can be applied while receiving a command for a specific power channel both via the network and from the short circuit sensor. So, for example, when the switch is open, the state of the power channel associated with it will be determined only by commands received via the information bus. When the switch is closed, the channel will be turned on and when it receives a command 000030

switching on via the bus, and when the corresponding short circuit sensor is closed (by pressing the corresponding touch button). And off - only if the bus receives a command to turn it off and the circuit breaker opens (releases the touch button).

In manual mode, all commands that change the state of the device can also be transmitted to the network via external input-output interface blocks (1) and plug-in modules of additional interfaces (8) both independently and upon request.

Also, in all modes, external controllers can read information about the current state of power channels.

Industrial applicability The device is completely self-sufficient, i.e. It works both as part of the system and independently, without any functional restrictions and additional external elements.

The proposed solution allows this device, after physically connecting switched loads, a supply voltage of 220 volts and external buttons (switches), to function both in a fully autonomous (manual) mode (without connecting external controllers via the information bus) and fully or partially controlled mode (when the state of the device outputs changes under the action of commands received on the information bus).

In standalone mode, the operation of each channel is manually set by the corresponding switch.

The presence of removable blocks of external interfaces allows you to adapt the device to any control environment of almost any manufacturer without changing the basic design.

The claimed device is fundamentally different from the existing ones in that, firstly, it provides maximum ease of connection and operation without involving a highly qualified specialist, and secondly, it provides the unprecedented reliability of the entire Smart Home management environment as a whole.

This solution completely eliminates the effect of two main inhibitory factors of the widespread introduction of control systems such as "Smart Home" - this is a high price and complexity of installation.

This solution, despite its simplicity, offers a fundamentally new approach to the construction of devices for control systems such as “Smart Home”. The implementation of devices in accordance with the proposed patent will allow you to get the best at this time, the indicator "price-quality".
