Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote start / stop control device that centrally controls start / stop of equipment such as a building from a remote location.

2. Description of the Related Art In recent years, an increasing number of facilities and equipment such as buildings are remotely controlled by a computer.

Conventionally, this type of remote start / stop control device has a configuration as shown in FIG. In FIG. 4, a central unit 101 for centrally controlling equipment 105 from a remote location is connected to a plurality of data repeaters 103 (1) to 103 (n) via the transmission line 102. The data repeaters 103 (1) to 103 (n) are respectively connected to a plurality of equipments via the lower transmission lines 104 (1) to 104 (n).
105 (1,1) to 105 (1, m) ... 105 (n, 1) to 105 (n, m) are connected.

The central device 101 has equipments 105 (1,1) to 105 (1, m) ... 105 (n, 1) to 10 for each of the data relays 103 (1) to 103 (n).
It has a data transmission means 106 for transmitting start / stop command data for starting / stopping 5 (n, m).

The data relays 103 (1) to 103 (n) have data receiving means 107 for receiving the start / stop command data from the central unit 101, and unique addresses to the data relays 103 (1) to 103 (n). Add to the address setting means 108 to be set, the address unique to each of the data relays 103 (1) to 103 (n) preset by the address setting means 108 and the start / stop command data sent from the central device 101. Address determining means 109 for comparing the received address and the address determining means 109, when the addresses match, a start / stop means 110 for transmitting a start or stop command signal to the connected equipment 105. have.

Here, arbitrary equipment 105 (i, 1) to 105 (i, m) connected to the arbitrary data relay 103 (i) (i = 1,2, ..., n)
The operation when activating (i = 1, 2, ..., N) will be described. First, the data transmission means 106 of the central unit 101 transmits start / stop command (start command here) data to which the address of the data relay 103 (i) is added. Data repeater 103 (1)
This data is received by all of the data relay devices 103 to 103 (n), but only the data relay device 103 (i) is addressed by the address determination means 109, and the , And the data relays other than 103 (i) do not match. Only the data repeater 103 (i) whose address does not match does not operate. The data repeater 103 (i) with the matching address is the start / stop means.
The 110 outputs a start / stop command symbol (start signal here) to the equipment 103 (i, 1) to 103 (i, m). As a result, the equipment 103 (i, 1) to 103 (i, m) to which the start / stop command signal is input
Will start. In the case of the stop, the stop signal is input in the same manner, and the facility devices 103 (i, 1) to 103 (i, m) are stopped. In this way, the facility device was started and stopped from the remote central device 101.

Problems to be Solved by the Invention In such a conventional configuration, when the central device 101 sends start / stop command data, the equipment 105n connected to the data relay 103n is activated or stopped all at once. Become.
This was not carried out except in special cases, because complicated wiring and many parts were required to sequentially start and stop many facility devices 105n by various groups, which was expensive. . Therefore, when many equipment devices 105n are simultaneously activated, an excessively large starting current flows, which causes a large drop in the power supply voltage, leading to a problem in starting failure.

SUMMARY OF THE INVENTION The present invention provides a remote start / stop control device in which the above-mentioned conventional problems are taken into consideration and a relatively simple means is added to prevent a start-up failure caused by simultaneous start-up of a plurality of equipment devices.

Becomes

EXAMPLE An example of the present invention will be described below with reference to FIGS. In FIG. 1, which is a central unit, a plurality of data repeaters 3 (1) to 3 (n) are connected via a higher transmission line 2. The data relays 3 (1) to 3 (n) are respectively connected to the plurality of facility devices 5 (1,1) to 5 (1, m) via the lower transmission lines 4 (1) to 4 (n). ... 5 (n, 1) to 5 (n, m) are connected.

The central unit 1 has equipments 5 (1,1) to 5 (1, m) ... 5 (n, 1) to 5 (n, m) for each of the data repeaters 3 (1) to 3 (n). It has a data transmission means 7 for transmitting start / stop command data for starting / stopping.

The contents of the start / stop command data are the address data of the data repeater, the start / stop group number, and the start / stop command type. The address data of the data repeater is the address of the data repeater to which the facility equipment to be started and stopped is connected.

What is the start / stop group of the start / stop group number? Data relay 3
The equipment 5 (1, 1) to 3 (n) connected to each
1), 5 (1,2), ... 5 (1, m), 5 (2,1), 5 (2,2) ... 5
(2, m), 5 (n, 1), 5 (n, 2), ... When 5 (n, m) is started and stopped, it is divided into groups and started and stopped for each group.

The types of start / stop commands are a start command when starting equipment and a stop command when stopping.

The data repeaters 3 (1) to 3 (n) receive the start / stop command data from the central unit 1 by the data receiving means 8, and the address determining means 9 addresses the designated data repeater in the start / stop command data. The data is compared with the address of any data relay 3 (i) (i = 1, 2, ..., N) preset by the address setting means 10 for setting a unique address for each data relay. .

Which start / stop group number is assigned to each facility device 5 (i, 1) to 5 (i, m) (i = 1,2,3, ..., n) connected to the start / stop group storage means. It remembers whether it belongs to the stop group.

The address determination means 9 of the sequential start / stop means 11 reads the start / stop group number in the start / stop command data when the address matches the value in the start / stop command data, and is indicated by the start / stop group number. Equipment 5 belonging to the start / stop group
Addresses of (i, 1) to 5 (i, m) are used as the start / stop group storage means.
The transmission / reception command signal is sequentially transmitted to each facility device with a delay of a certain time.

FIG. 2 is a flowchart showing the operation of the data repeater 3 (i). Here, it is assumed that the contents of the start / stop command data sent from the central unit 1 are that the address of the data relay 3 (i) is i, the start / stop group number is k, and the start command is sent.

First, at step 21, it is judged whether the start / stop command data from the central unit 1 is received by the data receiving means 8. If it has been received, the process proceeds to step 22, and if it has not been received, step 21 is repeated until it is received.
In step 22, the address data in the start / stop command data received by the address determination means 9 is read. Step 23
Then, the address determination means 9 further compares and determines the address read in step 22 with the address i of the data relay 3 (i) set by the address setting means 10. If the two values do not match, the process returns to step 21. If they match, go to step 24.

In step 24, the start / stop group numbers in the start / stop command data received by the start / stop means 11 are sequentially read. Since the start / stop group number is assumed to be k, in step 25, the start / stop group storage means 12 stores the stored equipment 5 (i,
Read addresses 1) to 5 (i, m). Here, the equipment that belongs to the start / stop group with the start / stop group number k is 5 (i,
2), 5 (i, 5), 5 (i, 6), 5 (i, 8), and an example of starting and stopping these equipments will be described below.

In step 26, the facility device 5 (i,
2) Start / stop (start here) command to the equipment 5
The (i, 2) address is added and transmitted. In step 27, it is judged by the starting / stopping means 11 whether or not there is another facility device to start / stop. Here, equipment 5 (i, 5), 5
Since there are (i, 6) and 5 (i, 8), the process proceeds to step 28. If there is no other equipment to start and stop, the process returns to step 21. Step 28 is a waiting time for starting and stopping the facility equipment 5 (i, 5) to be started and stopped next by delaying it for a fixed time. When this process is completed, the process returns to step 26 and the starting / stopping process of the equipment 5 (i, 5) is performed. In this way, the processing of steps 26 to 28 is repeated, and the start / stop processing of the equipment 5 (i, 6), 5 (i, 8) is also performed.

Equipment 5 (1,1) ... 5 (1, m), 5 (2,1) ... 5 (2, m),
... 5 (n, 1), ... 5 (n, m) is the terminal controller 6 (1,1) ...
6 (1, m), 6 (2,1) ... 6 (2, m) ... 6 (n, 1) ... 6 (n,
m). This terminal controller 6 (1,1) ... 6 (1,
m), 6 (2,1) ... 6 (2, m) ... 6 (n, 1) ... 6 (n, m)
It operates like the flow chart shown in FIG.

In step 31, the terminal controller 6 determines whether or not a start / stop command signal is sequentially sent from the start / stop means 11. If it is not sent, repeat step 31. If sent, go to step 32. Step 32 is any equipment 5 (i, j) added to the sent start / stop command signal.
The address of (i = 1,2, ..., n, j = 1,2, ..., m) and the equipment 5 (1,1) ... 5 (1, m), 5 (2,1) ... 5 in advance (2, m)
... 5 (n, 1) ... Compares with the address set on the 5 (n, m) side. If the two values do not match, the process returns to step 31, and if they match, the process proceeds to step 33 and the equipment 5 (i,
Start / stop (start or stop) j).

As described above, when the central apparatus 1 issues a start / stop command to a plurality of facility devices 5 at the same time, the facility devices can be sequentially started (or stopped) with a certain delay.

EFFECTS OF THE INVENTION As is apparent from the above description of the embodiments of the present invention, according to the present invention, a low-priced and relatively simple sequential start / stop means and sequential start / stop group storage means are added to the data repeater, and a central unit is used. By adding a start / stop group number when sending start / stop command data, it is possible to start / stop the equipment in sequence with a certain delay when starting / stopping equipment. It is possible to obtain a large practical effect that no start-up failure occurs.
