Abstract

PURPOSE:To use a calling sound generating function and a communicating function of a telephone set performing a comparison thereby to perform an operation of the comparison with efficiency by generating the calling sound to the telephone performing the comparison and communicating by using a receiver of the telephone to carry out a comparison operation. CONSTITUTION:After an operator connects a signal line of a telephone set with a main device by a conductive clip 50, only by an instantaneous short of the conductive clip 50, by an oscillating signal from an oscillating circuit 32, a calling sound is produced with respect to the telephone set. Then, in this manner, while any telephone set performing a comparison keeps to generate the calling sound, other operator takes a receiver from the telephone producing the calling sound performs an operation for turning OFF a hook switch. There by, by an elevation of an impedance between terminals of a main device P1, P1', an electric current value flowing to a diode section D2 of a second photocoupler is lowered and an output thereof is lost. Thereby, transistor sections Tr7, and Tr8 of the second photocoupler performing a magnetization of a relay -R are turned OFF together, and contacts r1, r2 of the relay -R return to positions as shown in the figure.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable telephone comparator used for providing predetermined wiring to a large number of telephones when installing the telephones.

[Prior Art] Traditionally, when installing telephones in buildings, etc., the telephone placed at a predetermined position receives a message.8 I! i) It is securely connected to a predetermined connection terminal such as a replacement terminal. As a result, a telephone line is established with the desired telephone set, and a telephone conversation can be made as appropriate.

For this reason, in the past, while measuring the impedance of the signal line of a telephone, the receiver of the telephone was picked up from the hook switch, and the change in impedance of the signal line that appeared at that time was measured. A check of compatibility with the telephone (hereinafter simply referred to as "contrast") was being carried out.

The problem that E'JI Ming tries to solve] However,
The method described above for comparing signal lines and telephone lines has the following problems.

? In episode '12, the place where the main body is located and the exchange dormitory are located and the place where the other end of the signal line of aircraft i is drawn out is separated by 1;A. There is.

Therefore, the P/L should be equipped with a device that allows at least two workers to carry out telephone calls, such as a telephone call machine, with one worker measuring the impedance of a given signal line, and the other person making a call from the telephone. The process of picking up the receiver is repeated for each telephone.

When the impedance measurer observes a change in impedance, he is instructed by another worker on the location of the telephone via radio, and connects the signal line of the telephone to the connection point of the signal line according to the instruction. It's definitely connected.

In other words, workers must always carry a means of communication, such as a radio, and picking up receivers from hook switches at random is an inefficient task when there are a large number of telephones to be compared. The working time was extremely long.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a submerged mobile telephone contrast device that can perform contrast operations efficiently and in a short period of time without using other communication means such as wireless communication. The purpose is

[Means for solving the problems] The means configured by the present invention to solve the above problems are as follows:
As shown in the basic configuration diagram of FIG.
a pair of connectors WM1 connected to the TL; an incoming signal transmitter M2 that sends an incoming signal to the telephone T via the connector M1 when the telephone T is in a signal receiving state; The transmitting/receiving unit M3 performs
The portable telephone contrast device is characterized in that it is equipped with a call signal transmitting/receiving section M4 that allows a telephone call to be made between the telephone T and the transmitting/receiving section M3 via the connector section M1 when the telephone T is in a talking state. This is the summary.

[Operation 1 The connector part M1 in the present invention is a part that performs electrical connection with the signal line TL of the telephone 11T, and
It can be easily and quickly connected to L, and the signal aTL can be connected easily and quickly.
Preferably, when the contrast is completed, the yc state can be resolved easily and quickly as well. Therefore, it is preferable to use components such as ordinary conductive clips.

The incoming call signal transmitter M2 outputs a drive signal for activating a ring bell or the like provided in the telephone T, and its output is transmitted to the telephone IT via the connector M1.

The transmitter/receiver section M3 is composed of a microphone, a speaker, etc., and the call signal transmitter/receiver section M4, which will be described later, converts the transmitted electrical signal into an audio signal, and also allows the user of this portable telephone contrast device to It converts the voice into an electrical signal and transmits it to the cough call signal transmitting/receiving section M4. In consideration of the user's work efficiency, the main sending/receiving section M3 has a separate configuration for sending and receiving calls, without any changeover switch, etc., so that there is no need to perform any operations during work, and is of a so-called headphone type. It is preferable that the structure is such that it can be easily attached to the body.

The call signal transmitting/receiving section M4 is for transmitting and receiving calls between the above-mentioned transmitting/receiving section M3 and the telephone 1jlT, and is for transmitting and receiving calls between the above-mentioned transmitting/receiving section M3 and the telephone 1jlT, and transmitting and receiving calls between the telephone operator and the transmitting/receiving section via the connector section M1. Mutual reception of electrical signals involves hand-off processing.

EXAMPLES Hereinafter, in order to explain the present invention more specifically, the present invention will be described in detail with reference to Examples.

[Example] Figure 2 shows II! a portable telephone comparator according to the example. FIG. In the figure, reference numeral 10 denotes a line testing handset as a transmitter/receiver part M3 worn by the operator, a holder 12 to be worn around the operator's neck, and a holder 12 for carrying the operator's voice for transmitting calls. It consists of a microphone 14 that converts the sound into an electrical signal, and an earphone 16 that allows the operator to receive a voice signal from a telephone under control, which will be described later. 30 is a main body having functions as an incoming call signal transmitting section M2 and a call signal transmitting/receiving section M4;
represents a conductive clip as the connector portion M1.

FIG. 3 is an electrical circuit diagram of the main body. In the figure, terminals P1 and P1' are terminals connected to a telephone via a conductive clip 50, and P2 and P2= are terminals connected to a line test handset 10.
Represents the terminal connected to. Reference numeral 31 denotes a power source installed inside the main body, and this power source 31 operates the portable telephone comparator. 32 is an oscillation circuit, which is a transformer (-1), a capacitor C1, and a transistor Tr1, and has a resonance frequency f-1/2πff (where, C is the inductance of the transformer L1, and C is the capacitance of the capacitor C1. ), and a UJTTr 2 that stops the operation of the transistor Tr1 in order to intermittent the oscillation.In this embodiment, the ring tone emitted from the telephone has a sound quality that is easy to interrupt. In order to achieve this, the resonant frequency f is selected to be 1 [KHz].

Reference numeral 34 denotes a ringing tone sending signal detection circuit, which converts the oscillation signal generated by the oscillation circuit 32 into terminals P1 and 2 by switching contacts r1 and 2 of relay R, which will be described later.
It has the function of transmitting the information to the Pi- and sending it to the telephone via the 1Iffi clip 50 described above. For this switching operation, the operator only needs to momentarily short-circuit the conductive clip 50. That is, when the conductive clip 50 is short-circuited, the resistance between the terminals P1 and Pi- becomes 0.
(Ω), and both ends of the diode portion D1 of the first photocoupler, which had been supplied with power up to that point, are short-circuited. As a result, the transistor portion Tr3 of the first photocoupler becomes 0.
FFL, , a transistor TrlbO that amplifies its output
FF. Therefore, Tr5, which obtains the inverted output of transistor Tr4, is turned ON for the first time in this state, and charging of capacitor C2 and output of transistor Tr6 are started. Since relay R is connected to the emitter of this transistor Tr6, relay R is energized and its contact r
1 and r2 are both driven from the illustrated state to form a closed circuit between the secondary side of the transformer L1 of the oscillation circuit 32 and the telephone set.

When the closed circuit is formed by the instantaneous show 1~ of the 4'21f clip 50, the diode portion D2 of the second photocoupler starts to be energized and is connected to the relay R by the operation of the self-holding circuit 36 described below. The excitation of is maintained.

That is, when the diode portion D2 of the second photocoupler included in the self-holding circuit 36 is activated, the transistor portion Tr7 of the photocoupler is turned on, and the transistor portion T
Transistor Tr8 driven by the output of r7 becomes conductive, and the relay R connected to its emitter continues to be energized.

Note that even if the short-circuit condition between terminals P1 and Pl is eliminated before the relay R is excited by the transistor Tr8, the transistor Tr6 remains in the ON state due to the discharge of the charge stored in the capacitor C2. The process then waits for the transistor Tr8 to turn on.

In this way, the operator of the present portable telephone contrast device connects the signal line of the telephone to the present device using the conductive clip 50, and then simply shortens the conductive clip 5.0 to generate the oscillation from the oscillation circuit 32. The signal can cause the telephone to ring.

Next, while the telephone set to be compared is still generating a ringing tone, another worker picks up the receiver of the telephone that is generating the ringing tone and hooks it up. Execute the operation to turn off the switch. Then, due to the rise in impedance between the terminals Pi and Pl of the portable telephone contrast device, the value of the current flowing to the diode portion D2 of the second photocoupler decreases and its output disappears.

As a result, the transistor section Tr7 and the transistor Tr of the second photocoupler, which were energizing the relay R,
8 are both 0FFt, and the contacts r1 and r2 of the relay R are returned to the positions shown in the figure.

As is clear from the figure, in this state, the line test handset 10 connected to the terminals P2 and P2' is connected to the telephone via the conductive clip 50 connected to the terminal P1.1]1-. The operator of the portable telephone control device, who was wearing the track test handset 10, and another worker who picked up the receiver of the telephone W that was emitting a ringing tone from the above-mentioned device. This makes it possible to make calls. Therefore, the operator of this device can determine at which position the signal line of the telephone that is currently connected by the conductive clip 50 of this device is connected to the telephone by talking with the other worker. You can receive instructions through the call.

As explained above, the mobile phone counter in this embodiment is
Simply connect the signal line of the telephone to be compared with a conductive clip 50.
After the clip is clamped and electrically connected, the telephone can generate a ringing tone simply by momentarily releasing the clip. This way, other ims don't have to do the inefficient task of picking up the receivers of all the phones at random, but they can pick up the handset of that phone because the phone that is running the control is ringing. By simply removing the telephone, and then using the device to make a call, it is possible to teach the necessary information such as the location of the telephone. Therefore, work efficiency is greatly improved, and the task of comparing a large number of telephones can be completed in a short time.

Furthermore, this device uses the short circuit of the conductive clip 50 as a type of switch, and there is no need to provide a separate switch for switching between the calling state and the talking state, thereby achieving miniaturization and cost reduction of the device.

Furthermore, if there is a fault in the signal line of the telephone, a rectangular tube with an impedance corresponding to the fault condition is connected to terminal P1. Since it is connected to P1-, the status of the fault can be known from the sound output from the earphone 16 of the line test transmitter/receiver m10.

[Effects of the Invention] As described above in detail with reference to the embodiments, the portable telephone contrast device of the present invention includes: a set of connectors connected to line 18 of the telephone; and the telephone in a signal receiving state. When the telephone is in a call state, a 6-signal signal transmitting section transmits an incoming call signal to the telephone via the connector section; a transmitting/receiving section transmitting and receiving calls; A feature of the present invention is that it includes a call signal transmitting/receiving section for executing a telephone call between the telephone and the transmitting/receiving section.

Therefore, it is possible to efficiently carry out the task of comparison by using the ringing function and the call function of the telephone performing the comparison. In other words, without having to randomly pick up the receiver of a telephone as in the past, the comparison task can be performed by generating a ring tone on the telephone that is performing the comparison and by making a call using the receiver of the telephone. It makes an excellent mobile phone comparator.
