Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device that controls air conditioning equipment, building management equipment, etc. through control calculations based on a combination of various basic calculation functions.

[Conventional technology]

Recently, control devices such as microprocessors (hereinafter referred to as CPUs) have been used as main components, and since the control calculations differ depending on the conditions at the installation site, addition and subtraction are required.

A standardized program is created for each basic calculation function such as multiplication, division, and each product logic process, and a program section for calculating the number of sheets is prepared in software, and these combinations are performed according to the conditions at the installation site. A standardized program and a program specifying silk stitching are stored in a fixed memory (hereinafter referred to as ROM) and installed in the apparatus.

[Problem that the invention seeks to solve]

However, once the equipment is actually delivered to the installation site and put into operation, there are likely to be differences between the original design conditions and the actual conditions, changes in the operator's requirements, etc., and furthermore, control conditions may change after the start of operation. Therefore, it is necessary to reconfigure the program, update the contents of the ROM, and replace the ROM, which increases the man-hours and expenses required on the manufacturer's side, takes a long time to update the contents of the ROM, and causes various problems. This has resulted in problems such as the inability to respond quickly to requests for changes.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention is constructed by the following means.

That is, a plurality of arithmetic program sections each having a basic arithmetic function and a plurality of types, a memory address in which input data used for the operation of each of the arithmetic program sections is stored are specified, and parameters used for the n11 operations are specified. and an intermediary file for storing the output data of the calculation results in each unit, and execution of control calculations by each calculation program unit by specifying each of the calculation program units individually.
an execution table for specifying the address of the intermediary file corresponding to each arithmetic program section in front of i, and sequentially selecting each arithmetic program section based on this execution table and specifying the intermediary file. An operation is performed using the input data of the address and the parameters of the intermediate file, and the output data and input data are exchanged between each operation program section in Rtl using the output data storage λ to the intermediate file. The system comprises means for controlling the control performance, and means for changing the contents of the intermediary file by input operation as necessary to change the situation of the control performance.

[Effect]

Therefore, the order of calculation by each calculation program section is determined based on the contents of the execution table, the address to be used in the intermediate file is specified by the address specification in the same table, and the address to be used is specified by the intermediate file. The input data is read from the memory address corresponding to υ, and the parameters are read from the intermediary file and used for calculations in the arithmetic program section, and this result is sent to the address of the intermediary file specified by the execution table. The output data is stored as output data, and the output data and input data are exchanged between the calculation program units, so that the control calculation is executed comprehensively.

Well, if you change the contents of the intermediary file by input operation and update the address of the input data, the data transfer status between each calculation program section will be different, and you can update the parameter values in the same way. However, the situation of control calculations will be different depending on the case.

Therefore, each BPR@BP l to BPn is executed sequentially according to the order of the execution table based on the management of O8, and if any one of 0DA34 is specified in IDA31, the output data of the previous operation is used as the input data of the current operation. 9, each BPR-BP
Output data and input data are exchanged between l-BPn, and a series of control operations are performed.

However, one BPR/BP is not necessarily executed only once, but may be executed multiple times depending on the contents of each OPG-Gz-Gm.

Further, control calculations are executed except for HDE22.35°43, etc.

FIG. 4 is an isometric block diagram showing the above-mentioned control calculation situation. , arithmetic program sections PA and PB each have an arithmetic input AI.

Therefore, the input data DII and DI2 are added, for example, in the arithmetic program section PA, and the output data DOI is used as the input data DI4 in the arithmetic program section P.
For example, after being multiplied with the input data DIs, the output data TX)s is obtained, but based on O8 (under the control of the CPU 1)

Then, BPR-BP Z and the intermediary files IDA@Bl, B2 and 0DA are similarly set by the execution table.
-B11 is selected and 0DA is selected according to the contents of IDA-B1.
-As is specified and the address CB can be specified by the contents of IDA-B2, so the output data IX) of 0DA-As and the input data DIa of address CB are not used in the execution of BPR-BP2. The output data 01)2 of is stored in 0DA-Bs.

In operations such as integration, differential operations, and coefficient multiplication,
Parameters such as an integral coefficient and a differential coefficient squared multiplication coefficient are stored in the PMA 32 of the intermediary file, and are used, and are temporarily stored in the 1INA 33 when the current calculated value needs to be used next time.

Regarding the above, when changing the control calculation situation to the state shown by the dotted line in Fig. 4, instructing to change the contents of the intermediary file by inputting KBl2,

By updating to DA-A3, the output data DO1 of the calculation program section Pi can be used as input data in place of the input data DIs.

That is, by updating the IDA 31 of the intermediary file according to the change conditions, input data can be arbitrarily determined.

Furthermore, when updating the contents of the PMA 32, the calculation coefficients can be changed freely.

42, the address of the AM3 is specified using the KBl2, the address is displayed on the CRTl2, and the content of the address is updated by performing a clearing operation and a setting operation.

Therefore, it is possible to easily and easily change the status of control calculations by inputting operations using KBl2.
Since the need to change the contents of M2 is eliminated, and it is possible to immediately take measures for changes in operating conditions, control conditions, etc. at the installation site, the time required to change the control calculation situation is shortened, and Required expenses become unnecessary.

The configuration shown in Figure 2 of Figure 2 can be selected arbitrarily.

Connect B and an operating device equipped with a liquid crystal display, etc. 1. , the same operation may be performed, and the same operation may be performed by remote control via the transmission line 10. As the transmission line 10, a wired line or a wireless line may be used depending on the conditions. .

Also, if the execution table is stored in RAM 3, it can be changed at will, but it can also be standardized like BPRIIBPI to BPn and stored in R, 0M2, and the number and contents of these steps can be changed depending on the situation. In addition, various modifications are possible, such as configuring each calculation unit not by a program but by hardware7 and controlling these by the CPU 1.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the control condition can be easily changed by input operation, so even if changes in control conditions, operational conditions, etc. occur, it can be easily and immediately dealt with. Various control devices,
