Known controller of remote objects according to the patent for utility model No. 89793 [1]. The known controller relates to the field of automation and telemechanics, namely to galvanically isolated controllers of remote objects (cathodic protection stations) using telemechanics complexes.

The well-known controller solves the problem of providing galvanically isolated digital control and operation of the cathodic protection station via a digital telemechanics channel, while expanding the functionality of the prototype. The known controller is not intended to increase the information capacity of the controller by connecting external modules.

The controller for utility model patent No. 64403 [2] is known, comprising a splash-proof housing with a cross-over board, which is a uniting unit on which the system module, power module, and necessary devices are installed to perform the basic functions of the product.

The controller has a modular design, a single enclosure, a system interface and a limited number of information channels.

This design does not allow its use at facilities requiring an increase in the number of connected sensors and actuators (i.e., an increase in its information capacity) without changing the design of the controller.

The technical result achieved by the utility model is to increase the information capacity of the telemechanics controller without changing its design.

The essence of the utility model is that a telemechanics controller containing a system module, a power module, input-output modules, a communication module operating under the control of the system module and integrated by means of a cross-board that provides electrical switching of the signal and power circuits, as well as connecting sensors and actuators from the first group of connectors, additionally contains external I / O modules connected to the system module via digital serial inter Eisa through the second and third groups of connectors, and external devices connected to the connector through the fourth group.

The connectors of the first, second, third and fourth groups are made in the form of terminal connectors.

In this case, the external modules are made in cases, on the lateral ends of which are located the terminal connectors of the third and fourth groups.

The telemechanics controller (figure 1, 2) is a housing 6 containing a limited set of built-in modules, including a system module 2, a power module 4, built-in input-output modules 3 (3.1 ... 3.3), a communication module 5. The power module 4 is a AC / DC voltage converter with backup battery, 5-GSM modem communication module.

I / O modules 3 are various combinations of input and output channels of both analog and discrete signals with a total number of up to 8 channels in one on the module. In an arbitrary set of modules, the modules contain analog signal input channels, discrete signal input channels, discrete signal output channels, and analog signal output channels. In the particular case, all I / O modules can be the same.

All these built-in modules are combined by means of cross-board 1, which provides electrical switching of signal 8 and supply 7 circuits, as well as the connection of external circuits from the first 9 and second 10 groups of connectors.

The sensors 12 and actuators 13 are connected to the first group of 9 connectors, which are connected to the input-output modules 3 by means of electrical circuits on the cross-board.

The system module 2 is connected via electrical circuits on a cross-circuit board with a second group of 10 connectors.

External digital input / output modules 15 (15.1 ... 15.n) are connected to the controller via a digital serial interface 14, sensors 12 and (or) actuators 13 are connected to each of them.

As sensors 12 control and / or measurement can be used sensors, respectively, level, flow, temperature, pressure, etc., designed to record and reflect in one form or another the current specific parameter.

Actuators 13 are understood as pump motors, gate valves, as well as various actuators, which serve to reposition the aforementioned devices.

External modules 15 are used to input signals from external sensors 12 and output signals to actuators 13. External modules 15 (15.1 ... 15.n) are connected to the system module 2 via the digital serial interface 14. Through the second group of connectors 10, they are used as digital serial interface can be adopted RS485 interface.

The external input-output modules 15 (Fig. 2) are enclosed in compact plastic cases 18. On the lateral ends of the cases 18 there is a third group of 16 connectors, through which the modules 15 are connected to the system module 2 through the second group of connectors 10 and a digital serial interface 14 .

In addition, at the lateral ends of the housings 18 there is a fourth group of 17 connectors, to which the sensors 12 and actuators 13 are connected.

The connectors of the first 9, second 10, third 16 and fourth 17 groups are made in the form of terminal connectors.

One of the parameters describing the properties of the controller is its information capacity “I” - the number of channels “i _k ” that receive input signals and the number of channels “o _j ” that provide connection of output signals (that is, I = i _k + O _j ) This parameter is set by the built-in input-output modules 3, which provide input and output signal connection and each of which contains from 4 to 8 channels of the corresponding type. Input channels (i _k ) provide reception of signals from sensors 12. Actuators 13 are connected to output channels О _j , the operation of which is controlled by signals from modules 3.1 ... 3.3.

The total number of sensors and actuators connected to the controller is limited by the number of input / output modules 3.1 ... 3.3 installed in the controller’s common housing 6 (I = I _contact ). This limits the total number of information channels in the basic configuration.

To increase the number of input / output modules in the controller, it is necessary to change its design. It is not possible to accomplish this on an existing facility.

The technical result that can be obtained by implementing the proposed technical solution is achieved as follows.

To increase the number of connected sensors and actuators without changing the design of the controller case 6, external I / O modules 15.1 ... 15.n with information capacity I _vn , working according to a single algorithm with modules installed in the general controller case, are additionally connected. The number and types of external modules 15 are limited only by the software used in the system module 2.

To increase the number of information channels, it is enough to connect external input / output modules 15 in the required quantity to the system module 2 via a digital serial interface 14, providing an increase in information capacity: I = I _contact + I _int .

The operation of the telemechanics controller.

The system module 2, installed in the controller case 6 and connected to the built-in modules: input-output modules 3, power supply module 4 and communication module 5, runs under the control of a program located in its memory. The system module 2 periodically reads information from the built-in input-output modules 3, to which signal sensors 12 are connected through the input connectors of the first group of 9 connectors, processes it and then sends it to the communication module 5 for transmission via the communication channel 11 to the information collection center. The commands from the system module 2 are received on the actuators 13 (for example, pump motors, electric gate valves, relays, etc.) through the input-output modules 3 and the connector of the first group of 9 connectors.

When connecting the external modules 15, the system module 2 periodically reads the information that is generated in the modules 15 from the sensors connected to the fourth group of connectors 17. The information received from the external modules 15 is processed by the system module 2 and sent to the communication module 5 for sending via the communication channel 11 to the information collection center. The commands to the actuators 13 connected to the fourth group of connectors 17 are received in the input-output module 15 from the system module 2 through the second group of connectors 10, the digital serial interface 14 and the third group of connectors 16.

An example of a specific implementation.

The telemechanics controller contains three input-output modules: an analog signal input module, a discrete signal input module and a discrete signal output module, each of which contains eight channels of the same type: an analog signal input module contains 8 channels of analog input signals, a discrete signal input module - 8 discrete input channels, discrete output module - 8 discrete output channels. Thus, I _contact = A ₈ + D ₈ + O ₈ = 24.

To add analog input channels to the basic configuration of the channels, two analog input modules are connected, eight channels each. The total number of external channels will be I _vn = 2 × 8 = 16. Thus, the information capacity of the controller increased and amounted to I = I _contact + I _ext = 24 + 16 = 40.

The given example is not exhaustive; it only illustrates the possibility of implementing a useful model.

The inventive utility model is implemented in the complex of technical means PK-300 (TU 4232-005-45985393) at the enterprise LLC "Sphere - MK", Krasnodar.

The inventive utility model provides the ability to optimally select the composition of the telemechanics controller depending on the complexity and information capacity of the telemechanization object, using the same controller for this purpose, supplementing it with external modules if necessary.

In addition, the ability to distribute I / O modules across the territory of the controlled object, bringing them closer to the place of installation of the sensors, saves connecting wires and reduces the complexity of installing the controller.
