Problems solved by technology

[0003] 1. The design of the filter circuit is cumbersome, the filter effect is not ideal, sometimes it will cause ringing misjudgment, and this part of the circuit adopts the form of two-stage drive and two-stage low-pass filter, resulting in large power consumption, especially not conducive to the portable magnet switch. low power design
[0004] 2. The components of the ringing detection circuit and the user call circuit are uniformly laid out and wired with other control units in the user circuit board, which leads to the problem of occupying a large area of ​​the PCB board and making it difficult to replace. , Changing the user capacity requires changes to the layout and wiring, which is very difficult to implement
[0005] In addition, the ringer used in current electronic telephones is usually an electronic bell, which is generally composed of a ringing ASIC, an oscillating element, and an output transducer. It directly uses the energy of the AC ringing signal sent by the switchboard. After being processed by an integrated circuit, it outputs high and low composite audio alternately according to the switching frequency, and pushes the speaker to ring. There is no signal level indicating the ringing detection result, and its disadvantage is that it cannot adapt to the function of a telephone with a microprocessor. Expansion; and the current telephone with ring detection usually uses an integrated circuit to complete the ring detection function, which is not conducive to the circuit debugging in the development stage and the secondary development of the telephone function

Embodiment 1

[0034] This embodiment is used for the switch magnet user interface board pick-up and hang-up detection, such as Figure 4 As shown in the figure, RD1-RDn represent n magnet user interfaces respectively. Taking the ring detection device applied to a 20-line magnet program-controlled switch as an example, if the switch needs 20 magnet users, 20 pieces of the plug-in The connected ring detection device is inserted into the 20-way slot of the user board motherboard. If the user demand is 16 channels, any 4 channels of the device can be plugged out according to the needs, which not only saves costs but also does not require special customization. The circuit diagram of this embodiment is as follows figure 2 shown.

[0035] The ring detection device for plug-in access includes a PCB (Printed Circuit Board, referred to as PCB) board, on which the following circuits are fixed:

[0036] A first input terminal and a second input terminal for inputting a two-wire ringing signal, one...

Embodiment 2

[0042] The ring detection device of this embodiment is applied to a telephone. When the built-in device of the telephone detects the ringing signal sent by the exchange, the microprocessor inside the telephone can perform various operations according to the information, such as starting a personalized ringtone or opening a telephone message. The schematic diagram of this embodiment is shown in Figure 5 As shown, the ring detection device is plugged into the circuit board of the telephone, so that the ring detection device forms a circuit connection with the microprocessor, and the telephone ring circuit or the voice message module is connected with the microprocessor. The two-wire ringing signal is input through the first input terminal P1 and the second input terminal P2. Other circuits are as in embodiment 1.

[0043] The plug-in ring detection device in this embodiment is convenient for maintenance and replacement; harsh environments such as lightning or other failures m...

Description

technical field [0001] The invention relates to switch or telephone technology, in particular to a ring detection device for switch or telephone. Background technique [0002] In the existing technology, the switches with magnet user interfaces are mainly magnet switches and a small number of common electric switches with multiple user interfaces and relay interfaces. The ringing detection circuit of the magnet user interface is mainly composed of rectification, voltage stabilization, limiting Flow, isolation control, and filter circuit are composed of several parts, but there are the following deficiencies: [0003] 1. The design of the filter circuit is cumbersome, the filter effect is not ideal, and sometimes it will cause ringing misjudgment, and this part of the circuit adopts the form of two-stage drive and two-stage low-pass filter, resulting in large power consumption, especially not conducive to the portable magnet switch. Low power consumption design. [0004] 2....
