BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a conceptual diagram showing a configuration of an electric device system A according to an embodiment of the present invention. The electric device system A includes an electric device main body 1 and a control unit 2. The control unit 2 is attached to the control unit attachment part 4 via the connection cable 3 and connected to the power supply unit 1.

In the present embodiment, a case will be described in which the electric device main body 1 is composed of a compressor that operates using a motor as a power source. As shown in the block diagram of FIG. 2, the electric device body 1 includes a motor 11 that moves the compressor 10, a pressure sensor 13 that detects the pressure of the tank 12 that stores the compressed air, and a winding (coil) of the motor 11. ) (Including the temperature of the control board if a control board is mounted in the motor housing) 14, the rotation detection sensor 15 for detecting the rotation of the motor 11, etc. Outside the situation of 1 A sensor 16 as a detection unit is arranged so that it can be grasped from the unit. The detection result of the sensor 16 is converted into a digital signal by the AZD conversion circuit 17 and fed back to the control unit 2 as a detection signal via the signal line 33.

[0016] It should be noted that the electric device main body 1 has a plurality of models in the same series (for example, in the case of a compressor, a plurality of models according to the output). The control unit 2 recognizes what type the electric device main body 1 is, and can control the electric device main body 1 appropriately.

[0017] The control unit 2 is a converter circuit that converts an original power source (for example, a household power source, a construction site power source, a generator, etc.) 21 connected via a power line 20 into a DC voltage for driving a motor. 22 and a switch circuit (inverter circuit) 23 that converts the DC voltage generated by the converter circuit 22 into a driving voltage for driving the motor 11, and a feedback signal (pressure, temperature, rotation, etc.) from the electric device body 1 ) To control the switch circuit 23 and control the voltage, frequency, etc. supplied to the electric device body 1 and the reading device 28 that reads the storage medium 27 such as the selection switch 26 or a memory card, etc. This is mainly composed of a setting unit (input unit) 29 for inputting various types of information to the control unit 25, a display unit 30 for displaying information input by the input unit 29, and a memory 31 for storing the set information. Composed. The control unit 2 can be electrically connected to the electric device body 1 by inserting the plug 34 of the connection cable 3 composed of the power line 32 and the signal line 33 into the connector 35 (see FIG. 3 (a)). .

[0018] Then, the control unit 2 can be detachably mounted on the control unit mounting portion 4 formed on the electric device main body 1. Make sure to connect the connectors directly without using the connection cable 3.

In addition, as shown in FIG. 3 (b), the control unit 2 is a selection switch 26 for manually operating a setting unit 29 for setting at what voltage and frequency the electric device body 1 is operated. You may comprise only. Further, as shown in FIG. 3 (c), it may be configured only by the reading device 28 that reads the storage medium 27 such as a memory card.

[0020] It should be noted that the selection switch 26 is set with a plurality of patterns specific to the electric device main body or corresponding to the machine number of the electric device main body, and the setting is switched according to the machine number by the switch operation. It only needs to be able to drive the main unit 1 [0021] The electric device main body 1 has identification information (for example, series product information (for example, air compressor product series number A100) for the control unit 25 to identify what type of electric device main body 1 is. A200, A300, B100, B200, etc.) and product-specific information (for example, serial number) may be registered in advance as identification information data in the internal memory 36. When the control unit 2 captures this identification information data Either the signal line 37 or the electric device main body 1 can be taken in by any method.

[0022] The identification information captured by the control unit 2 is input to the control unit 25, and the control unit 25 is capable of connecting the electric device main body 1 and the control unit 2 with good power. In this way, it is possible to determine how to control based on the identification information and to determine whether the control is right or wrong.

[0023] This identification information need not necessarily be provided on the electric device main body 1 side, and the identification information may be obtained on the control unit 2 side. For example, as shown in FIG. 3 (a), both a card reader 28 and a selection switch 26 are provided, and either a storage medium or a manual can be set, or as shown in FIG. 3 (b). In addition, it may be possible to set the identification information of the electric device main body 1 by operating the selection switch 26 provided in the control unit 2, or as shown in FIG. It is also possible to register identification information regarding the electric device main body 1 in advance in the medium 27 and read the storage medium 27 with a card reader 28 provided in the control unit 2.

Alternatively, the identification information may be transferred by an external communication means such as a remote controller.

[0025] The data of the storage medium 27 is registered in advance corresponding to the electric device main body 1 at the time of shipment, and the storage medium 27 in which the data is registered is attached to the electric device main body 1. It is also possible to prepare media 27 separately and have the data written at the manufacturer's service window.

[0026] Next, a procedure (unit installation flow) for causing the control unit 2 to recognize the electric device main body 1 when driving the electric device main body 1 by the control unit 2 is a flowchart shown in Figs. This will be described with reference to the drawings.

First, a procedure for registering information of the electric device main body 1 in the control unit 2 when the electric device main body 1 does not include identification information will be described based on the flowchart of FIG.

[0028] When the control unit 2 is mounted on the electric device main body 1 (step ST1), the input mode is entered (step ST2). When the information on the electric device main body 1 is manually set (switch operation), the process proceeds to step ST3. Determine whether or not to select the identification information from the table created on the memory 29 of control unit 2, and select it directly from the table without operating the selection switch 26. If this is the case, proceed to step ST4 and operate the selection switch 26 to select the main body 1 of the electric device, and the selection is displayed on the display unit 30 such as a lamp or liquid crystal display arranged in correspondence with the switch (step After step ST5), proceed to step ST7, set drive information (parameter information to be transmitted to the control unit 25 in order to properly operate the electric device main body), and then proceed to step ST8 for the next processing. That.

[0029] When selecting table power for identification information at step ST3, proceed to step ST7 to display and select series model data (series product information and control parameter information such as output, speed, and current), selection routine (processing routine) Enter 1). In this display selection routine, the selected data is displayed in step ST101. If the data can be used as it is and no correction is required, the process returns to the main routine and the drive information described above is set (step ST7). Proceed to step (ST8).

[0030] If correction of data is necessary, proceed to step ST103 to correct the data value! The correction is displayed. If registration is not required (step ST104), the main routine (step ST6 ), The drive information is set, and the process proceeds to the next process.

If data registration is required, the process proceeds to step ST105, where data is registered in the table, the process returns to the main routine (step ST7), drive information is set, and the process proceeds to the next process.

[0032] On the other hand, when the control unit 2 is provided with a reading device that reads the data of the storage medium 27 (memory card or wireless IC tag), the storage medium 27 is inserted into and brought into contact with the reading device. When reading (step ST9) and the medium cannot be recognized, the process proceeds to step ST11 to notify that the medium cannot be recognized and proceeds to the next process (step ST8).

[0033] If it can be recognized, the process proceeds to step ST12 to determine whether or not to select the table. If the control unit automatically determines and uses the information in the table, it proceeds to step ST13 and enters the display / selection routine (processing routine 1) of the series model data, and if the table data is not used, it goes to step ST13. Proceeding to ST14, reading the data in the storage medium 27, displaying the read information (step ST15), and if the displayed information is good (step ST16), proceeding to step ST7, the drive information described above is displayed. Set and proceed to the next process. If the drive information is not good, proceed to the next process without setting the drive information.

[0034] In the next processing described above (step ST8), similarly to the conventional electric device, the control unit supplies electric power to the electric device main body, and the electric device main body force is also fed back based on the signal fed back. The operation of the main body is controlled, and the operation of the normal electric device can be performed regardless of whether or not the control unit is separated. If the process proceeds to the next process (step ST8) due to an error notification, etc., it enters a standby state before the electric device body operates.

Next, a procedure for recognizing identification information when the electric device main body 1 includes identification information will be described with reference to the flowcharts of FIGS.

[0036] When the control unit 2 is mounted on the electric device main body 1 (step ST20), the identification information of the electric device main body is recognized (step ST21), and the electric device is mechanically shaped on the electric device main body side or an IC chip or the like. Determine whether the main unit can be identified (step ST22) .If not, proceed to step ST27 to notify the error. If determined, proceed to step ST23 to identify the unique information (electric device If there is no unique information, enter the input mode of step ST26. If there is unique information, proceed to step ST24 and enter the memory card or password. It is determined whether or not the passcode is correct. If they match, the process enters the input mode of step ST26. If they do not match, an error is notified in step ST27 and the next process is started.

[0037] In the input mode, it is selected whether to select automatically, switch operation, or storage medium 27 such as a memory card. In the case of automatic selection, the selected data is displayed on the display unit (step ST31), the process proceeds to step ST46, drive information is set, and the process proceeds to the next process.

[0038] In the case of switch operation, it is determined whether or not to select table information (step ST3 2) When selecting, proceed to step ST33 and proceed to the selection data processing routine (processing routine 2) for processing the selection data.

[0039] In this selected data processing routine, control parameter information is displayed in step ST111. If the data does not need to be corrected, the routine returns to the main routine (step ST46) to set drive information, and step ST47 Proceed to the next process.

[0040] If correction of data is necessary, the process proceeds to step ST113, where the data value is corrected and displayed. If registration is not required (step ST114), the process returns to the main routine (step ST46). Then, drive information is set, and the process proceeds to step ST47 to perform the next process. If data registration is required, proceed to step ST115, register the data in the table, determine whether it is within the identification information range (step ST116), and if within the identification information range, Returning to the main routine (step ST46), setting the drive information, proceeding to step ST47 and performing the next processing, if not within the range, returning to step ST111 and displaying the selected data again.

[0041] In the case of direct input, the process proceeds to step ST34 and the selection switch 26 is operated to select the electric device main body 1. When the electric switch body 1 is selected, a lamp or a liquid crystal display arranged corresponding to the switch 26 is selected. Is displayed (step ST35), the process proceeds to step ST36 to determine whether or not the identification information is within the range, and if it is within the range, the process proceeds to step ST46 to set the drive information, and the next process Go to (Step ST47).

[0042] When the storage medium 27 is selected, the storage medium 27 is inserted into or contacted with the reading device so that the reading device reads it (step ST37). If the medium cannot be recognized, the process proceeds to step ST39 and an error occurs. And proceed to step ST47 to perform the next process.

[0043] If it can be recognized, the process proceeds to step ST40 to determine whether or not to select the table. If the table information is used, the process proceeds to step ST45 to select the selection data for processing the selection data. Go to processing routine (processing routine 2).

[0044] In this selection data processing routine, the selection data is displayed in step ST111. If the data does not need to be corrected, the routine returns to the main routine (step ST46), drive information is set, and step ST47. Proceed with the next process.

[0045] If the table is not selected in step ST40, the process proceeds to step ST41, and the storage medium 2 7 data is read, the read information is displayed (step ST42), and it is determined whether the displayed information is within the identification information range (step ST43). Proceed to the next process. If the displayed information is within the range of the identification information, it is determined whether or not the information can be selected (step ST44). If not, the process proceeds to the next process (step ST47). Proceed to ST46, drive information is set, and the process proceeds to the next process (step ST47).

[0046] In the next processing described above (step ST47), similarly to the conventional electric device, the control unit supplies electric power to the electric device main body, and the electric device main body is based on a signal fed back from the electric device main body. Thus, the operation of a normal electric device can be performed regardless of whether the control unit is separated or not. Note that if the error notification notifies the next process (step ST47), it enters a standby state before the electric device main body operates.

[0047] According to the above configuration, although the control unit 2 is common to the electric device main bodies 1 for each series (for example, a plurality of types of compressors), the setting is made according to the electric device main body 1 to be used. Thus, it is possible to control the operation of the different electric device main bodies 1 with the same control unit 2.

[0048] In addition, since the electric device main body 1 side has a mechanical part (for example, a motor, a pump, etc.), the life is shorter than that of the control unit 2 side. If the side becomes unusable, the control unit 2 can be used as it is if only the electric device body 1 is replaced, and a system that is favorable in terms of cost and natural environment can be realized, If the electric device main body 1 and the control unit 2 are stored separately, even if the electric device main body 1 is stolen, the electric device main body 1 alone does not operate, so a crime prevention effect can be expected.

[0049] Although the invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. is there.
