Abstract

PURPOSE:To extend an input terminal equipment without correspondence to a master equipment by storing various processing routines being a basis of control data generation into the master equipment and transmitting an input data from the input terminal equipment and a data designating the processing routine to the master equipment. CONSTITUTION:The master equipment 1 transmits a signal requesting an address data AD to the input terminal equipment requesting interruption. When the request exists, the terminal equipment 2 returns the data AD during a return standby period. The master equipment 1 receives it and transmits a signal requesting the designation of a processing routine name to be executed to the terminal equipment 2. When the request is received, the terminal equipment 2 returns a data A of a designated processing routine name and an input data ID to the master equipment and completes the interruption. Then the master equipment 1 decides the data A from the terminal 2, calls the processing routine from the storage section, processes the data ID in the processing routine and transmits the control data obtained as a result at accessing of an output terminal equipment 3. Then the terminal equipment 3 fetches the control data and outputs a control output CD to an external equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a multiplex transmission remote device using time division multiplex transmission or the like.

[Background Art] Conventionally, in this type of multiplex transmission remote device that is equipped with a large number of terminal devices and performs remote monitoring and control, the main device has conventionally been equipped with an input terminal for monitoring and an output terminal for control. It was necessary to make a correspondence. Therefore, when adding an input terminal, there is a problem in that it is necessary to perform processing to associate the input terminal with the tiller.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to eliminate the need to perform processing to associate each input terminal with a base unit each time an input terminal is added. There is no multiple transmission to provide a remote control device.

[Disclosure of the Invention] FIG. 1 shows the overall schematic configuration of an embodiment of the present invention,
The input terminal 27J and the output terminal 3 are connected to each other via a transmission line. In the figure, only one input terminal 2 and one output terminal 3 are connected, but normally a plurality of input terminals 2 and output terminals 3 are connected. The input terminal 2 takes in the on/off signals of various sensors and A/D converted data, and converts the input data ID into parent $1! by time-sharing or the like. ! This is for transmitting to 1. The base unit 1 includes a processing routine A1 for creating various control data in advance;
A2, . The address data and control data that disturb the output are transmitted by time division or the like, and the output terminal 3 is normally accessed cyclically to monitor the control status. If the output terminal 3 receives a call from the parent 8!11! +Control data is imported and external equipment is controlled based on the control data.

Figures 2 and 3 show 70 operations of the base unit 1 and input terminal 2.
- This chart shows that when there is a change in the input data ID in the input terminal 2, an interrupt request pulse P is cyclically transmitted from, for example, the base unit 1, as shown in FIG. 4(A). It is generated at the timing of the start pulse SP of the transmission signal. When the main device 1 receives this interrupt request, a signal 1 is sent to request the address data AD of the input terminal device 2 that requested the interrupt, as shown in FIG. 4(B).
'(C is transmitted. When the input terminal device 2 receives this request, it returns the address data AD during the return waiting period RP.The input terminal device 1 receives the interrupt request from the input terminal device 1 according to the returned address data AD. 2, and then transmits a signal RC' requesting the input terminal 2 to specify the name of the processing routine to be executed and requesting transfer of the input data ID, as shown in FIG. 5(A). When this request is received, the input terminal 2 returns the data A of the specified processing routine name and the input category ID to the base unit 1 as shown in FIG. 5(B).Then, the interrupt ends. Next, the base unit 1 determines the data A of the designated processing routine name sent from the input terminal 2, calls the processing routine from the storage unit 4, and sets the input data ID to the processing routine. The control data obtained as a result of this processing is transmitted when a predetermined output terminal 3 is accessed.When accessed, the output terminal 3 takes in the control data and outputs the control output CD to an external device. It outputs and controls external equipment.

The input data for the input terminal 2 may be temperature data from a temperature sensor, and the external device for the output terminal 3 may be an air conditioner for heating and cooling.For example, if the room temperature is 28.
Assuming that cooling is performed when the temperature is above 13°C, and heating is performed when the temperature is below 13°C, the following control is performed in the apparatus of the present invention. The input terminal 2 converts the analog output of the temperature sensor into a digital quantity by AD converting it, compares it with a comparator, and outputs data corresponding to room temperature below 13°C.
.

lcl, DcoIll for the case from 13°C to 28°C,
The case of 28°C or higher is designated as Dhot. The input terminal 2 then takes in these data. On the other hand, the processing routine name of the base unit 1 for air conditioning is assumed to be DRa1r. For example, if the room temperature changes from 26°C to 29°C, the input data ID on input terminal 2 is Dcoll.
The input terminal 2 requests an interrupt from the base unit 1. The base device 1 requests and confirms the address data of this input terminal device 2, and after this confirmation, input data I
D and the specified processing routine name. Input terminal 2
The processing routine name D air and room temperature data D are sent to base unit 1.
Send hot. When the data is sent, the master device 1 reads out the processing routine Dair from the storage section 4 and executes it. In this processing routine, the room temperature data Dhot is used, and since the room temperature data is Dhot, the main device 1 sends control data to turn on the cooling device to the output terminal 3 connected to the cooling device of the air conditioner. The output terminal 3 turns on the cooling device according to this control data.

Although the above specific example relates to control of air conditioning equipment, it goes without saying that the invention is not particularly limited to this.

[Effects of the Invention] The present invention is configured as described above, and includes means for storing various processing routines that are the basis for creating control data in the base unit,
Since the input data and the data specifying the processing routine are transmitted from the input terminal to Iliso, it is only necessary to provide the input terminal with an address for confirmation at the time of an interrupt. , there is no need to allocate addresses that correspond to input terminals and output terminals, so when adding or deleting input terminals, no system changes other than adding or removing input terminals are required. There is an effect that
