Description

The present invention relates to a control system and an electronic circuit module that control an actuator via a network.

Conventionally, actuators for IoT (Internet of Things) have been developed, but there are few cases that lead to social implementation. One of the factors was the technical aspect and cost of constructing a control system for controlling the actuator via the network.
For example, there are cases of IoT, remote monitoring and control using inexpensive board computers such as Raspberry Pi (registered trademark) and Arduino (registered trademark) (Patent Document 1), but there are the following problems.

(I) You need to program your computer.
(II) It is necessary to modify the hardware and program when changing the actuator or communication method.
(III) There are unnecessary unused functions installed in the board computer.
(IV) It is difficult to divert the system because the usage and data are different for each application.

It is also conceivable to control the actuator using a commercially available controller, but when trying to build a system for IoT using the controller, the actuator is connected to the controller and the controller is connected to the network. Therefore, it is necessary to monitor and control the controller via the network, which is troublesome and costly. In addition, in order to support new technologies such as communication and actuators, it was necessary to make major system changes. In addition, encryption technology for ensuring the reliability and credibility of digital data for control is also required. In the conventional IoT-related technology, a control system that is simple, low-cost, versatile, easy to update functions, and highly reliable has not been known.
In addition, by satisfying the power supply and signal specifications of this system, it becomes easy to add newly developed actuators and modules to the system.

The actuator adjustment data includes, for example, ratio / bias data, correction data for linear correction, and the like. Reading the actuator ID (identification information) data and the actuator adjustment data is not an essential process in the present invention.

Next, the data correction unit 235 of the DA module 2 contains control data in the digital data decoded by the decoding unit 231 and stored in the memory 24 (YES in step S401 of FIG. 7), and the data is corrected. (YES in step S402 of FIG. 7), the control data is corrected based on the actuator adjustment data (step S403 of FIG. 7). The case where data correction is necessary is, for example, the case where the actuator adjustment data read from the actuator 4 by the data reading unit 234 exists.

Further, as another correction process, there is a process of correcting the non-linearity of the operation of the actuator 4 by correcting the value indicated by the control data to be corrected based on the correction data. As is clear from the above description, these correction processes are not essential processes in the present invention.

The data output unit 232 of the DA module 2 outputs the control data corrected by the data correction unit 235 or the control data stored in the memory 24 that does not require data correction to the DA conversion unit 25. The DA conversion unit 25 converts the control data received from the data output unit 232 into an analog signal (step S404 in FIG. 7).

The processes of steps S401 to S405 are repeated until the power supply is exhausted (YES in step S406 of FIG. 7).

FIG. 8 is a block diagram showing an example of the configuration of the actuator 4. The actuator 4 includes a communication / power supply / reception male connector 40, a controller 41, and a motor 42. The controller 41 generates a motor drive voltage corresponding to an analog signal (for example, a 4-20 mA current signal) received via the communication / power supply / reception male connector 40, and outputs this motor drive voltage to the motor 42. As a result, the motor 42 rotates at a speed corresponding to the analog signal.

The above operation can be realized by connecting the actuator 4 to the DA module 2, connecting the DA module 2 to the NW module 1, and connecting the NW module 1 to the power supply 3. The cloud server 101 can operate the actuator 4 by transmitting the encrypted digital data obtained by encrypting the control data to the NW module 1 via the network 100. Further, the cloud server 101 can also set the parameters of the NW module 1 and the DA module 2 by transmitting the encrypted digital data obtained by encrypting the communication parameter setting data or the DA conversion parameter setting data.

When it is necessary to calculate the control data based on the control amount of the control target of the actuator 4 (for example, the movement amount or the rotation amount of the object moved by the actuator 4), the control amount data measured by the sensor is used in the network 100. It is necessary for the cloud server 101 to calculate the control data based on the collected data. However, the present invention is not limited to such a control data generation / calculation method, and can be applied regardless of the control data generation / calculation method.

In this embodiment, an example in which the NW module 1 performs wireless communication is described, but wired communication may be performed. In this case, the NW module 1 may be connected to the network via the communication connector 18. When the communication circuit 19 receives a packet from a cloud server on the network via the communication connector 18, the communication circuit 19 extracts encrypted digital data from the packet and passes it to the communication unit 140 (step S100 in FIG. 3).
