Abstract

PURPOSE:To eliminate the common equipment (main equipment) of large scale, by dividing terminal equipments into the groups of plural equipments having the same function, providing a master equipment in each group, and performing data transfer between groups through the master equipment. CONSTITUTION:The data transfer is performed among respective terminal equipment of a call and a non-call systems, the main equipment 11a, that is the master equipment of each group, a security master equipment 13a, and a telecontrol master equipment 12a. For example, when a central office outgoing, etc., is requested as a result that sensor information from a security slave equipment 13b is sent out (data transfer), a system is constituted so that the data transfer(d) is performed between the security master equipment 13a and the main equipment 11a(11a'). In other words, no direct data transfer is performed between the main equipment 11a and each terminal equipment of the noncall system, and control between them is distributed in respective master equipment 12a, or 13a, and only when control information related to line control, etc., exists, the data transfer between the equipment and the master equipment 12a, or 13a is performed.

Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a terminal system control method in which a large number of terminal devices with different functions are connected to a common signal line for data transmission). For example, it can be used as a control method for a button telephone device.

"Prior Art" Figure 2 is an example of a terminal system in which a large number of terminal devices with different functions are connected to a common path for data transmission, and the control method of a conventional key telephone device is explained below. FIG. Note that the path connection is branch type,
It is easy to change to a star-shaped connection.

Reference numeral 1 denotes a central office line, a two-digit main device, and 3-1, 3-2, and 3-n key telephones, which are connected to the main device 2 by paths 4 in large numbers. The path 4 is composed of a communication path 4a and a data path 4b. From the main device 2 to each button telephone 3-
1 to 3-n control and each button telephone 3-1 to 3-
Control such as a request for a central office line connection from n to the main unit e2 is performed by data transmission via the data path 4b.

Therefore, the main device 2 and each button telephone 3-1 to 3-n
Each of the key telephones 3-1 to 3-n is provided with input/output means such as push buttons and displays.

5-1 to 5-m and 6-1 to 6-1 are devices having functions (non-call type) different from the functions (talk type) of the above-mentioned pushbutton telephones 3-1 to 3-n. -1~5-m
is a so-called security terminal device having a function of monitoring the operating status of electrical equipment, opening/closing of doors, etc., and each input circuit is equipped with a sensor 5a.

5m is connected, and the status information of these sensors 5a and 5m is sent to the main device 2 as a data signal, and under the control of the main device 2, the security terminal devices 5-1 to 5-
The system is configured to generate an alarm sound between M and M, or to call an external telephone or the like via the central office line 1 as necessary to notify the above-mentioned monitoring information.

6-1 to 6-1 are devices with further different functions (non-telephone type), such as so-called teleconverter terminals that are configured so that the power of electrical equipment can be turned on and off from an external telephone via the central office line 1. It is. 6a.

61 is a power outlet to which electrical equipment is connected. All operations are controlled by the main device 2. The control signal transmission method for this purpose is as follows:
~ 5-m and the teleconverter terminal devices 6-1 to 6-1 by a polling method, and the control signals are sent to the main device 2 so that each terminal device responds to the control signals. be exposed. FIG. 3 is an example of a synchronization pulse and a data signal according to the above-described control signal transmission method.

In FIG. 3, M is the signal sent by the main unit 2, T+
, Tt are button telephones 3-1 to 3-n, respectively.

The signals from the security terminal devices 5-1 to 5m and the teleconverter terminal devices 6-1 to 6-1 are shown for two representative devices.

The teleconverter terminal devices 6-1 to 6-1 turn on and off the power outlet 6a (61) according to the control signal from the main device 2.
Although some devices are configured to control F, they are usually configured with an additional function to send the above control results as data signals to the main device 2. Generally, the data transmitting/receiving circuit is connected to communication equipment. Something similar is provided.

a is a synchronization pulse, g, to g4 are data signals, b is the address code of the self (source), address code of the cI/i destination, d is the instruction code of the control signal (telegram length), and e is the instruction code of the control signal (telegram length). Control signal (14, sentence) code, f is check code.

In the figure, the content of the destination address code C of the data signal g is the address code of, for example, the key telephone 3-1, which corresponds to the signal waveform TI. Therefore, upon reception of this data signal g, the button telephone set 3-1 of the corresponding address sends out a data signal g to call it.

Next, the main device 2 specifies the address of, for example, the key telephone 3-2, which corresponds to the signal waveform T, and sends out a data signal g. Thereafter, in the same manner, the main device 2 sequentially transmits and receives data signals to and from communication and non-communication equipment, thereby carrying out the operations described above.

As explained above, since the main device 2 is equipped with all the functions for controlling terminal devices having different functions (call type and non-talk type), the main device 2 can be operated using conventional buttons such as
It is necessary to control not only the security terminal devices 1 to 3-n but also the security terminal devices 5-1 to 5m and the teleconverter terminal devices 6-1 to 6-1, which results in an increase in the number of control programs and an increase in memory capacity. It becomes impossible to control with a simple CPU, and an expensive CPU becomes necessary.

In addition, in the polling method, the teleconverter terminal devices 6-1 to 6
-1. As the number of security terminal devices 5-1 to 5-m increases, it takes longer to access all the terminal devices, resulting in an increase in system response time.

Furthermore, in the conventional control method, it is necessary to configure the main device 2 according to the maximum number of terminal devices that can be added, but the number of additional devices varies depending on the user, and it is particularly desirable to increase the number of non-call-related functions in stages. There are many obidome.

Therefore, with conventional control methods, it is difficult to construct an economical system that meets these demands, and improvements have been required.

[Problems to be solved by the invention] The present invention aims to provide a control method for a terminal system that is hierarchical by function so that the system can be configured economically according to the actual situation of each user as described above, and that does not impair the mass production effect. That is.

"Means for solving the problem" In a control method for a terminal system in which a large number of terminal devices with different functions are connected to a common signal line for data transmission, each terminal device with the same function is In addition, each group is provided with a base unit, and the base unit is configured to perform data transmission with terminal devices within the group, and data transmission between groups is performed via each base unit. This is what I did.

Embodiments and Effects FIG. 1 is a system diagram of a button telephone device showing an example of a hierarchical configuration based on a control method of a terminal system according to the present invention. 11
, 12 and 13 indicate groups in which terminal devices having different functions are divided into the same functional group. 11 is a terminal device for the call group, 11a
Fi main unit, Ilb.

The telephones 11n are arranged in multiple stages, and are configured so that data transmission (a) such as push button information and lamp control information is carried out using the main device 11a as a master device.

12a with 12Fi non-call group teleconverter terminal equipment
l'f7-recon base unit, t2b, 123-digit teleconverter slave units are installed in multiple stages, and data such as outlet information, lamp control information, etc. c) is configured to be performed. There are 13 security terminal devices constituting the other non-calling group, where 13a is a security base unit 1, 13b is a security base unit, and 13m is a security slave unit in multiple stages, and the security base unit 13a and security slave unit 13b are similar to the above.

The structure is such that data transmission (b) of sensor information, lamp control information, etc. is carried out over a distance of 13 m.

Data transmission for each of the groups 11, 12, and 13 described above is performed through a common signal line based on a synchronization pulse sent from the main device 11a.

FIG. 4 is a block diagram showing the connection state and data transmission state of the terminal devices according to the system diagram of FIG. 1.

Groups 11, 12, and 13 are connected to a common bus 4 as in the conventional case, but in the present invention, normally, each terminal device of a communication system and a non-communication system and a base unit of each group are connected to a common bus 4. Data transmissions (a), (b), and (c) are performed between the main device 11a, the security base unit 13a, and the teleconverter base unit 12a. As mentioned above, the main device 11a has a synchronization pulse sending function for this purpose, as well as a function for line control, which will be described later, which are all the same as those possessed by the conventional main device 2, so detailed explanations will be omitted. In FIG. 1, it is shown as 11a separated from the main device 11a. )have. Therefore, for example, the sensor information from the security handset 13b is sent (
As a result of data transmission (b), if it is necessary to make a call to a central office line, etc., the security main unit 13a
(lla') for data transmission). In other words, the main device 11a does not directly transmit data to each of the non-communication terminal devices, but its control is distributed to the respective parent devices 12a and 13a, and the main device 11a only transmits data to the parent devices when there is control information related to line control, etc. Machine 12a,
13a) and (e) are performed for data transmission.

Next, the data transmission method will be explained in detail.

FIG. 5 is an example of synchronization pulses and data signals in the control method of the present invention.

Signals Ts and T4 sent from the main device 11a are signals sent from, for example, telephones 11b to 11n, and two representative telephones are shown. S and s2 are signals from non-communication equipment, such as signals from the sexiness main unit 13a and the sexiness handset 13b.

a synchronization pulse, data path 4b as described in FIG.
and received by each terminal device. The reason why no data is transmitted or received after sending the first synchronization pulse a is because no terminal device needed to send a control signal. Data is sent and received only when it is necessary to do so. For example, the data signal g activates the sensor 13 b' of the security child fi 13b, which causes the security child device 13b to connect to the security parent device 13a.
This is the case when a control signal is sent to The structure of the data signal is the same as that in FIG. 3, so the same reference numerals are given. That is, the address code C of the destination at this time corresponds to the security master unit 13aK. Therefore, the data signal gs is received by the security base unit 13a. If the content of the control signal e at this time is that it is necessary to notify a predetermined party (subscriber) that the sensor 13b has been activated, the security main unit 13a transmits the address code C of the destination. The data signal g6 with the main device 11a as the main device 11a is sent out. As a result, main device 1
1a calls a predetermined subscriber.

The circuit configuration etc. for this purpose may be the same as the conventional one, and since it is not directly related to the present invention, a detailed description thereof will be omitted.

If the content of the control signal e of the data signal g is such that, for example, it is enough to simply cause another security slave device to generate a message tone, etc., the security master device 13a sends the address code C of the destination to the appropriate address code C. Needless to say, data transmission (b) is performed using the security cordless handset.

For example, when a data signal gy is received on the office line l, the data signal gy is
1a sends a control signal e for displaying an incoming call to all telephones 11b to fin in the call group 11, and the address code C of the destination in this case is It is designed to be specified by an address code, for example "0", which is not assigned to the terminal device.

The data signals ga and ga are explained in the case where there are duplicate terminal devices that need to send control signals.

That is, in the present invention, data transmission is performed only when there is a terminal device that needs to send a control signal as described above, so that the above-mentioned duplication may occur. Therefore, in the present invention, priority is given to each terminal device as described later. data signal g
, and g8 are cases between telephones in call group 11, but the same applies to cases with other groups. In the figure, when the telephone corresponding to the signal waveform T4 sends out its own address code b', it knows that another telephone with a higher priority is sending out the data signal gs, so it sends out the data signal g. An example of canceling the process midway through is shown. In this case, the destination address code C corresponds to the main device 11a, which is the parent device of the own group. As a method for detecting the presence or absence of data signal transmission by a terminal device with a higher priority than itself, for example, a terminal device with a higher priority can detect the time t from the synchronization pulse a to the start of data signal transmission. Shorten the address code b (
b) A method is adopted in which the presence of a dominant address code is detected by simultaneously receiving other data signals bit by bit of the address code and comparing it with this. The latter method is particularly effective when there are a large number of terminal devices.

Now, in order to perform the above-mentioned control, each group 11, 12, 13 is given a priority order among the groups. For example, group 13 is at the top, then group 11. They are assigned in the order of group 12, and the base unit 11a is at the top of each ranking.

12a and 13a are allocated. The priority order of each terminal device is then assigned in correspondence with its own address.

That is, addresses of terminal devices are assigned in order from the group with the highest priority. For example, if security group 13 is assigned to the highest priority, the security and IJ tea base unit 13a will not be assigned the highest priority, and the next group, for example, the main unit 11a which is the base unit for group 11, will be assigned the security slave unit 13m. will be ranked next.

In other words, if two terminal devices need to send control signals at the same time, priority is given to data transmission within the group with the highest priority, and then data transmission between the parent device of that group and the parent devices of other groups is prioritized. It will be appreciated that data transmissions occur in an order with priority being given to data transmissions within the next next highest group.

In the embodiment, a case has been described in which the main unit 11a is provided with the function of sending out the synchronization pulse a for data transmission, but the function is not limited to this, and the function may be provided to either of the other main units 12a or 13a. The above-mentioned control can be performed even if the Moreover, no special equipment is required for the synchronization pulse sending function and the data signal transmission/reception circuit.

When adding terminal devices, it is possible to sequentially connect them to the bus 4 by assigning addresses assigned within that group to the terminal devices.
Therefore, there is no need to change the control circuit of the main device 11a having a line control function.

In addition, since a large number of terminal devices with different functions are distributed and controlled in the same functional group, layering is possible.

"Effects of the Invention" As explained above, according to the present invention, in a control method for a terminal system in which a large number of terminal devices with different functions are connected to a common signal line to perform data transmission, the same function can be performed. A plurality of ≠ 3 terminal devices are divided into groups, each group is provided with a base unit, and the base unit is configured to perform data transmission with the terminal devices within the group, and data transmission between the groups is , because it is done through each parent device, a large-scale common device (main device)
The system can be expanded in units of functional groups even when expanding to increase functions, and the system can be configured economically according to the actual situation of the user. Also, the addition of terminal equipment made it possible to use earthenware.

Since there is no need to change the control circuit of the device, a mass-produced terminal system can be realized.
