Definitions
- the invention relates to the technical sector of production, conversion, distribution of electrical energy, in particular to the control or regulation of motors, electric generators or converters, as well as to the technique of electrical communication.
- the object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
- the problem which the invention proposes to solve is to be able to remotely control at least one, but generally several electrical components, such as electric motors, from a central unit by eliminating all the conventional control devices, such as contactors. , relays, timers, clocks, variable speed drives, etc.
- a device has been designed and developed.
- remote control and monitoring of at least one electrical member of the motor type in particular, from a local two-wire and / or optical information bus network remarkable in that: it comprises at least one / central unit connected to the network;
- the central unit sends operating instructions to a dialogue unit capable of processing them and transmitting them to a management and power unit;
- the management and power unit is determined to order different actions for power modules, said unit being able to collect information on the physical states of said power modules, in order to transmit them to the dialogue unit which is connected to the central unit via the bus;
- the power modules are connected to an electrical supply and to the electrical component.
- the device limits the wiring and the supply of electricity by motor, and requires only a control link by a local information bus network. All functions can be added or removed at will, without modifying the wiring, taking into account a specific program of the central unit. This results in a significant reduction in costs compared to a conventional electrical installation.
- the power modules include:
- the power modules also include, in particular in the context of a rotating electrical member, in the form of a motor:
- the protection module has an electrical switching power.
- the dialogue unit, the management unit and the various power modules are integrated in a housing.
- the box is inserted at the level of the electrical member.
- FIG. 1 is a purely schematic view showing an example of command and control of several motors by means of the device according to the invention
- FIG. 3 shows, on the one hand, the design of a housing inserted at the level of the electrical member in the form of a motor for its command and control by means of the device according to the invention, and , on the other hand, its coupling with other engines;
- FIG. 4 is a purely schematic view showing a front view of an engine powered by the device according to the invention.
- FIG. 5 is a view corresponding to Figure 4, the engine being shown by a rear view;
- the device according to the invention makes it possible to remotely command and control one, but generally several electrical members, such as electric motors of the asynchronous or synchronous type, and allow these the latter to perform several physical functions by means of a remote control via a local two-wire information bus network.
- the device receives information from a central unit (CPU) in the form of an operating instruction.
- a central unit CPU
- these operating instructions can be, start and stop order, speed and direction of rotation, torque, acceleration and deceleration ramp, braking, etc.
- a dialogue unit (I I) and transmitted to the power management unit (10) which can order different actions for power modules (3, 4, 5 and 6).
- the power modules are connected to an electrical supply (a1), and connected at the level of the electrical component, for example to the armature (7) of a motor (2) .
- the power management unit (10) collects various information on the physical states of the power modules and transmits this information to the dialogue unit (1 1), by sending it back to the central unit (CPU) via the network. local bus (a2) thus ensuring maintenance (figure 2).
- the type of power modules used may depend on the information that one wishes to collect.
- the device can implement an electronic protection module (3) of the motor supply (2), in order to secure the device.
- the power modules can consist of: - a current rectifier (4), in order to obtain direct current; - an assembly (5) capable of reducing the harmonic currents, and composed of a choke and a capacitor; an inverter (6) composed of power transistors.
- the motor (2) can also be subjected to a temperature probe (8) and to a quartz vibration detector (9).
- the engine via the power management unit (10), can also be subjected to forced ventilation (12).
- the dialogue unit (11), the power management unit (10), the various power modules (3, 4, 5, 6, 9, 12) are integrated in a housing (B).
- the box (B) is provided with two inputs (01 and 02) to allow connection to the power supply (al) and to the control (a2) by the local two-wire information bus network.
- the housing (B) can be integrated into the motor
- the protection module (3) may have an electrical switching capacity.
- the device finds a particularly advantageous application for the remote control and monitoring of several electric motors (2) to allow the motor to perform several physical functions via a local bus network.
- the figures in the drawings show the parallel mounting of several motors (2) with their housing (B) between the general supply (al) and the local bus network (2a2). Given the characteristics of the device and its application to the control and command of several motors, devices can therefore perform, using network information (a2) the following functions given by way of indicative example, in no way limiting : - motor start-stop function; variation of a rotation speed according to the setpoint by frequency variation;
- the device can perform, independently, the following functions: thermal self-regulation with transmission of information to the network; - detection of the vibration rate with information sent back to the network;
- the device includes, in a compact manner, inside a housing, the various modules and their function, thus limiting the wiring and the supply of electricity. and to a control link via a two-wire information bus network.
