JP2503418B2 - Attendant handler detection device for automatic telephone exchange - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to an automatic telephone exchange, and more particularly to a circuit configuration for automatically detecting the presence or absence of a relay operator.

[Conventional technology]

Conventionally, this type of terminal device absence detection circuit has a built-in electronic key 211 in the terminal device 210 as shown in FIG.
Operator presence / absence signal (on / off signal) by operation 1
Is configured to be transferred to the central control device 201 via a photo coupler 202 incorporated in the device main body 200.

[Problems to be solved by the invention]

However, conventionally, a signal for detecting the presence or absence of the operator of the relay stand is output to the manual operation of the electronic key 211. However, it is impossible to notify the telephone from the absence of the attendant who handles the relay console, resulting in a problem that the service to the customer is significantly deteriorated. Also, especially at night, etc.
Forgetting the operation of 1 causes a big problem because the call coming from the customer at night cannot be transferred to the direct call at night.

An object of the present invention is to provide a detection device that eliminates any operation error by the operator of the relay stand.

[Means for solving problems]

In order to achieve the above object, a relay board operator detection device for an automatic telephone exchange according to the present invention is a relay board operator detection device for an automatic telephone exchange having a transmitter, a receiver, and a detector, The transmitter is carried by a relay operator who is involved in the relay work of a telephone exchange. The radio field intensity of the transmitter is such that when the relay stand operator stands up, the transmitter is separated from the receiver by a predetermined distance. At this time, the level of the radio wave received by the receiver is set to be below the threshold level of the receiver, and the receiver is installed in the relay stand of the automatic telephone exchange and receives the radio wave from the transmitter. The detector detects if the radio wave level from the transmitter received by the receiver is below the threshold level of the receiver.
It detects that the attendant is away from the attendant.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a transmitter 120 that can be carried by a relay console operator 113 of an automatic telephone is provided, and the transmitter 120 is caused to emit a radio wave of a certain level.

On the other hand, a receiver 111 is installed in the relay stand 110, and a transistor 112 as a detection unit for detecting the presence or absence of a relay stand operator is provided.
Is connected to the output side of the receiver 111, and the output side of the transistor 112 is connected to the central control unit 101 via the photocoupler 102 of the apparatus main body 100.

In the embodiment, it is assumed that each of the relay stand operators 113 carries the transmitter 120 and engages in relay work. Where the transmitter
The signal strength of 120 is the receiver when the operator 113 stands up.
When the transmitter 120 to the 111 is separated by a predetermined distance, the receiver
It is set so that the level of the reception radio wave of 111 becomes below the threshold level of the receiver 111.

Therefore, when the relay stand operator 113 is engaged in the relay work, radio waves of a certain level come into the receiver 111 from the transmitter 120 carried by the operator 113, and the receiver 111 has an internal control circuit. The transistor 212 is operated via. Upon receiving the output of the transistor 212, the central control unit 101 maintains the exchange processing state by the relay operator 113.

On the other hand, when the operator is away from the seat, the level of the received radio wave is small and the level is below the threshold level of the receiver 111, so that the transistor 212 is in the recovery state. Based on this information, the central control unit 101 is configured so as not to hinder the replacement process that accompanies the attendant leaving the desk.

〔The invention's effect〕

As described above, according to the present invention, the presence / absence of the operator is detected by receiving the radio wave from the transmitter carried by the operator of the relay stand, so that the operator particularly operates when standing up. There is no need, and there is an effect that all obstacles due to operator's operation mistake can be eliminated.
