  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

  Hereinafter, a control apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  First, an outline of the configuration of the control device of the present invention will be described. The control device of the present invention includes one or more peripheral devices that can be directly operated from a microcomputer (CPU) such as AD input and port input, a hardware interface for accessing an extended IC (Integrated Circuit), and transmission and reception using this interface. It is equipped with an interrupt function that can notify the completion timing of the memory, a storage device such as a ROM (Read Only Memory) and a RAM (Read Only Memory).

  FIG. 1 is a system configuration example of a control device 1 according to an embodiment of the present invention. Although only the input system of the control device 1 is shown in the figure, the output system may be configured similarly (the input system and the output system do not have to correspond one-to-one). Assuming that the input system and the output system are symmetric, the input can be read as output in the following description.

  The extension IC 10 is equipped with a hardware interface for accessing the microcomputer, and communicates with the microcomputer by, for example, serial communication. The extended IC 10 has functions 12 and 13 that can be operated from a microcomputer via a hardware interface, such as AD input and port input.

  The software executed by the control apparatus 1 according to the present embodiment and the data handled by the software are mainly an application layer (hierarchy) 20, a device driver layer 30 including one or more device drivers, and an intermediate layer I / O service layer 40 is hierarchically divided.

[Application layer]
The application layer 20 includes application software 21. The application software 21 performs processing for performing various device controls based on signals input via the I / O service layer 40.

[Device driver layer]
The device driver layer 30 functions as a driver for devices including peripheral devices with built-in microcomputers to the extended IC 10. In this embodiment, an AD converter is exemplified as a peripheral device with a built-in microcomputer.

  The device driver layer 30 has I / O allocation information (information for converting signal names into channels) for all channels of the target device. For example, the device driver layer 30 includes microcomputer AD input allocation information 31A and extended IC allocation information 31B.

  The microcomputer AD input assignment information 31A is assignment information for all signals connected to the AD converter of the microcomputer. FIG. 2 is an example of the microcomputer AD input allocation information 31A. For example, the I / O allocation information 31A corresponds to the signal ID, and stores a device ID, a port number, a channel number, a hardware circuit logic, and the like. The extended IC allocation information 31B is allocation information for all signals connected to the AD converter of the extended IC 10. FIG. 3 is an example of the extended IC allocation information 31B. The extended IC allocation information 31B corresponds to, for example, the signal ID, and stores a device ID, a port number, a channel number, a hardware circuit logic, and the like.

  The device driver layer 30 has a terminal operation interface for accessing the input data buffer from the I / O service layer. For example, the device driver layer 30 includes a microcomputer AD input I / F (interface) 32A, an extended ICAD input I / F 32B, an extended IC function BI / F 32C, and an extended IC function CI / F 32D.

  The microcomputer AD input I / F 32A is an interface through which an I / O service for AD input acquires data from the microcomputer. The extended ICAD input I / F 32B is an interface through which an I / O service for AD input acquires data from the extended IC 10. The extension IC function BI / F 32C and the extension IC function CI / F 32D are interfaces for the I / O service for the function B and the function C of the extension IC 10 to acquire data from the extension IC 10.

  The device driver layer 30 has an input data buffer for the interface. For example, the device driver layer 30 includes a microcomputer AD data buffer 33A, an extended ICAD data buffer 33B, an extended IC function B data buffer 33C, and an extended IC function C data buffer 33D.

  The microcomputer AD data buffer 33A stores the AD conversion result (AD value) of the microcomputer in channel order. The extended ICAD data buffer 33B stores the AD conversion result (AD value) of the extended IC 10 in the order of channels. The extended IC function B data buffer 33C and the extended IC function C data buffer 33D store the input values of the functions B and C of the extended IC 10.

  The device driver layer 30 includes a microcomputer AD receiver 34A and an extended IC communication unit 34B.

  The microcomputer AD receiver 34A periodically instructs the microcomputer AD conversion Obj51 to perform AD conversion, and stores the AD conversion result in the microcomputer AD data buffer 33A.

  The extended IC communication unit 34B periodically communicates with the extended IC 10. Then, the data portion is extracted from the received frame and stored in the buffer (33C, 33D) for each function. The extended IC communication unit 34B includes a transmission buffer 34Ba and a reception buffer 34Bb.

  In the device driver layer 30, the microcomputer AD input allocation information 31A, the microcomputer AD input I / F (interface) 32A, the microcomputer AD data buffer 33A, and the microcomputer AD receiver 34A are software packages corresponding to the AD converter of the microcomputer. . Further, the configuration other than these is a software package corresponding to the extended IC 10. When a change, addition, deletion or the like occurs in the peripheral device built in the control device 1 or the expansion IC 10 connected thereto, the change, addition, deletion or the like is performed in units of software packages as described above.

[I / O service layer]
The I / O service layer 40 is for realizing the concept of virtualizing I / O functions for devices including peripheral devices and the extended IC 10 and fixing them as I / O services. For example, an AD input service (fixed part) 41 for providing a service that can be used with a plurality of signals), an AD input service (variable part) 42 that changes according to the difference in equipment, and allocation information supplied from the device driver layer 30 And an allocation information disclosing unit 43 that publishes them to the AD input service (fixed unit) 41.

  The AD input service (fixed unit) 41 is a fixed logic that does not require a change for each device. The AD input service (variable unit) 42 is a signal ID list in which signal IDs assigned to the AD input service (fixed unit) 41 are listed, for example. The allocation information disclosure unit 43 bundles the allocation information of all driver packages into a data block of a certain format (hereinafter referred to as I / O allocation information), and then discloses it to the AD input service (fixed unit) 41. This eliminates the need for the AD input service (fixed unit) 41 to be aware of which device the signal corresponds to.

[Other layers]
In addition to the above-described layers, the control device 1 of the present embodiment includes a MCAL (Microcontroller Abstraction Layer), a microcomputer as a hardware, a device, and the like.

  The MCAL includes a microcomputer AD converter Obj (object) 51A that is an access module of the microcomputer AD converter block 52A, and a microcomputer serial communication Obj51B that is an access module of the microcomputer serial communication block 52B.

  Various signal groups are input to the microcomputer AD converter block 52A. Here, it is assumed that signals ZZZ and YYY are input.

  The microcomputer serial communication block 52 </ b> B performs communication with the extension IC 10 including the AD converter block 11. It is assumed that signals VVV and WWW are input to the AD converter block 11 of the extension IC 10.

[Signal flow]
The flow of signals from the application software 21 to the device in the control apparatus 1 having the above configuration will be described.

  The application software 21 calls the I / O service layer 40 by specifying the signal ID.

  In the AD input service 41 of the I / O service layer 40, the device and channel number corresponding to the signal ID are extracted with reference to the allocation information disclosure unit 43, and the corresponding input interface (32 </ b> A to 32 </ b> D) is selected in the device driver layer 30. call.

  When outputting data to the device, the data is output to the input interfaces (32A to 32D). In the input interface of the device driver layer 30, the input data is written into the data buffers (33A to 33D). Then, the data is output to the designated channel of the peripheral device or the extension IC 10.

  On the other hand, when data is input from the device, data written to the data buffers (33A to 33D) by the microcomputer AD receiver 34A and the extended IC communication unit 34B is output to the I / O service layer 40. The data output to the I / O service layer 40 is output to the application software 21.

[Processing flow]
Hereinafter, the flow of processing executed by each component included in the control device 1 of the present embodiment will be described.

  FIG. 4 is a flowchart showing the flow of processing executed by the microcomputer AD receiver 34A. This flow is repeatedly executed.

  First, the microcomputer AD receiver 34A waits until a regular trigger occurs (S110).

  When a periodic trigger occurs, an AD conversion request for all channels is issued to the microcomputer AD converter Obj51 (S120).

  Next, it waits until AD conversion is completed (S130).

  When AD conversion is completed, AD conversion results for all channels are acquired from the microcomputer AD converter Obj51, stored in the microcomputer AD data buffer 33A (S140), and one routine of this flow is terminated. As a result, the microcomputer AD data buffer 33A is updated with the latest AD conversion result.

  FIG. 5 is a flowchart showing a flow of processing executed by the extended IC communication unit 34B. This flow is repeatedly executed.

  First, the extended IC communication unit 34B waits until a regular trigger occurs (S210).

  When a periodic trigger occurs, AD conversion commands for all channels are written (written) to the transmission buffer 34Ba (S220).

  Then, the function B command is written to the transmission buffer 34Ba (S230), and then the function C command is written to the transmission buffer 34Bb (S235).

  When these commands are written to the transmission buffer 34Bb, a transmission request for all commands in the transmission buffer is issued to the microcomputer serial communication Obj51B (S240).

  If a transmission request is issued, it waits until communication is completed (S250). During the communication, an AD conversion result or the like is received from the extension IC 10 and stored in the reception buffer 34Bb.

  When the communication is completed, AD conversion results for all channels are extracted from the reception buffer 34Bb and stored in the extended ICAD data buffer 33B (S260). Similarly, the reception data from the function B of the extension IC 10 is extracted from the reception buffer 34Bb and stored in the extension IC function B data buffer 33C (S270). Next, the reception data from the function C of the extension IC 10 is received by the reception buffer 34Bb. Is extracted and stored in the extended IC function C data buffer 33D (S275), and one routine of this flow is terminated.

  FIG. 6 is a flowchart showing the flow of processing executed by the AD input service (fixed unit) 41. This flow is executed when the application software 21 designates a signal ID and gives an instruction to acquire an AD value.

  First, the AD input service (fixed unit) 41 substitutes a value representing an error into the “AD value” (S310). Such processing is to set an error value as a default value in advance in case the signal ID specified by the application software 21 does not exist.

  Next, the designated signal ID is searched from the signal ID list (S320).

  Then, it is determined whether or not the signal ID exists on the signal ID list (S330). If the signal ID does not exist on the signal ID list, the “AD value” is called and returned to the original application software 21 (S380). In this case, the value representing the error substituted in S310 is returned to the application software 21 as “AD value”. As a result, when the designated signal ID does not exist, the application software 21 and thus the user can be notified of unauthorized access.

  If the signal ID exists on the signal ID list, allocation information (for example, device ID, port number, channel) of the corresponding signal ID is acquired from the I / O allocation information (S340).

Next, an AD input I / F name to be called from the device ID is assembled (S350). Specifically, the name of the AD input I / F (terminal operation I / F) is, for example, “[device ID] _
If the device ID of the corresponding signal is “micom”, “micom_
If the device ID is “extic”, it is expanded to an IF of “extic_get_ad ()”.

  The processes of S340 and S350 may be statically expanded using a preprocessor.

  Next, an AD input I / F (microcomputer AD input I / F 32A or extended ICAD input I / F 32B) assembled using the port number and channel number as input data is called (S360).

  Then, the return value from the called AD input I / F is substituted into the “AD value” (S370), and the “AD value” is called and returned to the original application software 21 (S380).

  FIG. 7 is a flowchart showing a flow of processing executed by the microcomputer AD input I / F 32A. This flow is executed when an acquisition of an AD value is instructed from the application software 21 via the AD input service (fixed unit) 41.

  First, the microcomputer AD input I / F 32A takes out an AD value corresponding to the designated port number or channel from the microcomputer AD data buffer 33A (S410). At this time, the data structure can be concealed from the AD input service (fixed unit) 41 and the application software 21 by setting the I / F name to “micom_get_ad ()” and a function interface.

  Then, the extracted AD value is returned (returned) to the AD input service (fixed unit) 41 via the I / O service layer 40 (S420).

  FIG. 8 is a flowchart showing a flow of processing executed by the extended ICAD input I / F 32B. This flow is executed when an acquisition of an AD value is instructed from the application software 21 via the AD input service (fixed unit) 41.

  First, the extended ICAD input I / F 32B extracts the AD value corresponding to the instructed port number or channel from the extended ICAD data buffer 33B (S510). At this time, the data structure can be hidden from the AD input service (fixed part) 41 and the application software 21 by setting the I / F name to, for example, “Extic_get_ad ()” and using the function interface.

  Then, the extracted AD value is returned (returned) to the AD input service (fixed unit) 41 via the I / O service layer 40 (S520).

[Comparative example]
Here, a comparison between the control device 1 of the present embodiment and the control device of the conventional configuration will be described. FIG. 9 is a system configuration example of a control device 700 having a conventional configuration. The control device 700 having the conventional configuration does not include components corresponding to the I / O service layer 40 included in the control device 1 of the present embodiment.

  Similarly to the control device 1, the extension IC 710 is connected to the control device 700.

  Software executed by the control device 700 having the conventional configuration and data handled by the software are mainly divided into an application layer (layer) 720 and a device driver layer 730.

  The application layer 720 includes application software 721. The application software 721 performs processing for performing various device controls based on the signal input via the device driver layer 730.

  The device driver layer 730 functions as a driver for devices including a peripheral device (for example, an AD converter) with a built-in microcomputer to an extended IC 710. The device driver layer 730 has I / O allocation information (information for converting signal names into channels) 731 for all channels of the target device.

  The device driver layer 730 includes input buffers such as a microcomputer AD data buffer 733A, an extended ICAD data buffer 733B, an extended IC function B data buffer 733C, and an extended IC function C data buffer 733D.

  The microcomputer AD data buffer 733A stores the AD conversion result (AD value) of the microcomputer in the order of channels. The extended ICAD data buffer 733B stores the AD conversion result (AD value) of the extended IC 710 in the order of channels. The extended IC function B data buffer 733C and the extended IC function C data buffer 733D store the input values of the function B and the function C of the extended IC 710.

  The device driver layer 730 includes a microcomputer AD receiver 734A and an extended IC communication unit 734B. The microcomputer AD receiver 734A periodically instructs the microcomputer AD conversion Obj751 to perform AD conversion, and stores the AD conversion result in the microcomputer AD data buffer 733A. The extended IC communication unit 734B periodically communicates with the extended IC 710. Then, the data portion is extracted from the received frame and stored in the buffers (733C, 733D) for each function. The extended IC communication unit 734B includes a transmission buffer 734Ba and a reception buffer 734Bb.

  Further, the device driver layer 730 includes an AD input service 736. The AD input service 736 includes an [AD data name]-[signal ID] correspondence table 736A and a [device ID]-[AD data buffer name] correspondence table 736B. [AD data name]-[signal ID] correspondence table 736A is a correspondence table between AD data names and signal IDs, and [device ID]-[AD data buffer name] correspondence table 736B is a device ID and AD data buffer ( 733A, 733B) is a correspondence table of software variable names. The AD input service 736 includes portions that need to be changed for each model, and aggregates functions related to AD input across a plurality of devices.

  The other layers are the same as in the first embodiment. Description is omitted.

  FIG. 10 is a flowchart showing a flow of processing executed by the AD input service 736 provided in the control device 700 having the conventional configuration. This flow is executed when the application software 721 designates an AD data name and instructs acquisition of an AD value.

  First, the AD input service 736 assigns a signal ID from internal data from a designated AD data name (S810). Specifically, for example, the signal ID “ZZZ” is assigned to the AD data name “addata_zzz”.

  Next, allocation information (for example, device ID, port number, channel number, hardware circuit logic, etc.) of the corresponding signal ID is acquired from the I / O allocation information 731 (S820).

Next, the corresponding AD data buffer name is assigned from the device ID from the internal data (S830). For example, from the device ID “micom” to the data buffer name “micom_adinp_
Assign adbuf [] ”.

  Next, the corresponding AD data is extracted using the port number and channel number acquired in S620 as an array index (S840). For example, when there is no port number and channel number 0, “micom_adinp_adbuf [0]” is referred to.

  Then, the AD data extracted in S640 is returned to the application software 721 (S850).

  In the control device 700 having a conventional configuration, the device driver layer 730 is configured by three elements of a data buffer for each device, I / O allocation information 731, and an AD input service 736 that provides a service to the application software 721.

  However, in such a configuration, there is no concept of virtualizing up to I / O functions and fixing them as I / O services, and there is no mechanism for realizing such a concept. The services to be provided are different, and it is difficult to cope with the insertion / extraction (difference between chipsets) of a plurality of different devices including a microcomputer.

[effect]
On the other hand, in the control device 1 of the present embodiment, the universal I / O function is fixed to the AD input service (fixed unit) 41 as the I / O service, so the I / O service can be provided only by hardware specifications. The development period of application software can be shortened.

  In addition, since the part that does not change depending on the model (AD input service (fixed part) 41) and the part that changes depending on the model (AD input service (variable part) 42) are separated, the number of software components can be reduced. In addition, the amount of ROM used and the labor of coupling can be reduced.

  In addition, when the same function (for example, AD input) is installed in multiple devices, the terminal operation interface for accessing the input buffer of each device is standardized, so the connection destination switching logic is easy using the I / O assignment information. Can be realized. The standardization means that only the device name included in the interface name is different, and the other parts are the same.

  In addition, since the software package in the device driver layer 30 is created for each device, the device can be easily inserted and removed. Therefore, it is possible to easily cope with various hardware configurations.

  According to the control device 1 of the present embodiment described above, it is possible to flexibly cope with a change of a connected device.

[Example of implementation]
The control device according to the present invention can realize the following functions.

  For example, AD input, HI / LO input (ON / OFF input), input latch function, etc. can be realized as input system functions. In this case, the data buffer can be periodically updated for each device. In order to notify the update timing to the application software, the update timing for each device may be notified to the application software, or the latest update timing among a plurality of devices may be notified to the application software.

  Similarly, output functions such as AD output and HI / LO output (ON / OFF output) functions can be realized.

  Further, a pulse output system function can be realized as an output system function. In this case, the output service functions to output a duty, a periodic pulse, a one-shot pulse, a timed edge, and the like. Each function in the I / O service fixing unit (the “AD input service (fixed unit) 41” in the embodiment is replaced with an output service and generalized) is reentrant if it is a different signal. . Data for each signal is placed in the I / O service variable part ("AD input service (variable part) 42" in the embodiment is replaced with an output service and generalized) and can be accessed from the I / O service fixed part. And Since reentrancy (reentrant) of the same signal is complicated, it is not guaranteed by the I / O service layer 40 and is set not to be executed by the application software 21.

  The I / O service variable unit includes a signal ID list, a constant corresponding to the number of signals to be supported, and a variable storage area (arranged for the number of signals). Then, the timing at which the signal has changed is notified to the application software 21 using the interrupt function of the microcomputer as necessary.

  Similarly, a pulse input system function can be realized as an input system function. In this case, the input service functions to input a duty, a periodic pulse, a one-shot pulse, a timed edge, and the like. In this case, the timing at which the signal has changed is notified to the application software 21 using the interrupt function of the microcomputer as necessary. Then, at the notification timing, a function call is made with the data included in the pulse (duty [%], pulse period [us], edge generation time [us], etc.) as arguments, and the timing and data are simultaneously sent to the application software 21. Notice.

[Deformation etc.]
The best mode for carrying out the present invention has been described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. And substitutions can be added.
