Abstract

PURPOSE:To eliminate a trouble due to the operation error of an operator by receiving a radio wave from a transmitter carried by a B-board operator and detecting whether the operator is present or absent. CONSTITUTION:A receiver 111 is provided in a B-board 110, a transistor 112 as the detecting part to detect whether a B-board operator is present or absent is connected to to output side of the above-mentioned receiver 111 and the output side of the transistor 112 is connected through a photocoupler 102 of a device main body 100 to a central control unit 101. When a B-board operator 113 is engaged in the relaying work, the radio wave of a constant level enters the receiver 111 from a transmitter 120 carried the operator 113, and the receiver 111 operates a transistor 212 through an internal control circuit. While the operator leaves a seat since, the level of the receiving radio wave is low and is the threshold level or below of the receiver 111, the transistor 212 comes to be the recovering condition. The central control unit 101 does not hinder the exchanging processing accompanying the leaving of the seat of the B-board operator based upon the information.

Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an automatic telephone exchange, and particularly to a circuit configuration that automatically detects whether an attendant is present or absent.

[Conventional technology]

Conventionally, this type of terminal device absence detection circuit has a built-in electric key 211 inside the terminal device 210, as shown in FIG. The data is configured to be transferred to the central control device 201 via a photocoupler 202 built into the main body 200.

[Problem that the invention seeks to solve]

However, conventionally, the signal for detecting the presence or absence of the attendant is output to the manual operation of the electric key 211, so if the operator forgets to operate the telephone key 211 when leaving his/her seat, In this case, it is not possible to notify customers that the attendant is not present when they call, resulting in a problem in which service to customers is significantly degraded. In addition, if you forget to operate the Ia 21 especially at night, a big problem will occur because calls from customers during the night cannot be transferred to the night direct dial phone.

An object of the present invention is to provide a detection device that eliminates any operational errors by relay stand operators.

[Means for solving problems]

The present invention provides a portable transmitter that emits radio waves at a certain level;
A receiver installed on a relay stand of an automatic telephone exchange and receiving radio waves from the transmitter, and a detection unit detecting the presence or absence of an operator at the relay stand based on the output signal of the receiver. This is a characteristic feature of a relay stand operator detection device for special telephone exchanges.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, a transmitter 120 is provided which is portable for a relay stand operator 113 of an automatic telephone, and the transmitter 120 is caused to emit radio waves at a certain level.

On the other hand, a receiver 111 is installed in the relay stand 110, a transistor 112 serving as a detection unit for detecting the presence or absence of an operator at the relay stand is connected to the output side of the receiver 111, and the output side of the transistor 112 is connected to the device. Photocoupler 1 of main body 100
02 to the central control unit 101.

In the embodiment, each of the attendants 113 has a transmitter 12.
0 and engage in relay work.

Here, the radio field intensity of the transmitter 120 is such that when the transmitter 120 moves a predetermined distance in front of the receiver 111 due to the operator 113 getting up from his/her seat, the level of the radio waves received by the receiver 111 becomes higher than the threshold of the receiver 111. Set it so that it is below the shoulder level.

Therefore, when the relay stand operator 113 is engaged in relay work, a certain level of radio waves enters the receiver 111 from the transmitter 120 carried by the operator 113, and the receiver 111 is connected to the internal control circuit. The transistor 212 is operated via the . In response to the output of transistor 2]2, the central control unit 101 maintains the replacement processing state by the relay stand operator 113.

On the other hand, when the operator is away from the seat, the level of the received radio waves is low and therefore below the threshold level of the receiver 111, so the transistor 212 enters the recovery state. Based on this information, the central control device 101 is configured so as not to interfere with the exchange process due to the departure of the attendant.

〔Effect of the invention〕

As explained above, the present invention detects the presence or absence of a relay stand operator by receiving radio waves from a transmitter carried by the relay stand operator, so that the operator does not have to perform any special operations when leaving his/her seat. There is no need for this, and it has the effect of completely eliminating problems caused by operator errors.
