Description

Multi-channel signal auto-monitoring controller

The utility model relates to a kind of multi channel signals and patrols the survey controller automatically.

There is Japanese music AG-SW100 type to patrol the survey controller automatically in the market, it can form audiovisual reproduction and loop monitoring system thereof with a television picture monitor, ten video recorders, ten players, plays the effect of each audio-video channel signal being patrolled automatically survey.But there is following weak point in this product:

1. be provided with preparatory function, when patrolling survey automatically, can not select arbitrarily all passages (including the passage of signal input and no signal input).

2. purposes is single, only suits to use aspect audiovisual reproduction.

3. input channel is few, and circuit structure is more complicated, is not easy to the expansion of number of channels.

4. complete machine weight is big, the cost height.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of hyperchannel to patrol the survey controller automatically.

The purpose of this utility model can reach by following measure:

(1) is frequency dividing circuit, provides selection of time the conducting of each passage.

(2) be control system, can produce various control signals by each function button on the guidance panel.

(3) be nixie display, can carry out numeral to the sequence number of each input channel of being output and show.

(4) be decoding monitor, to address code decoding and carry out power amplification.

(5) be counting circuit, produce address code.

(6) be memory circuit, measurement information is patrolled in storage automatically.

(7) be latch cicuit, address code is latched.

(8) be hyperchannel switch (A), can from the multichannel input, select a kind of as output.

(9) be hyperchannel switch (B), can from the multichannel input, select a kind of as output.

(10) be power switch, the through and off of may command 220V AC power.

(11), can make controller be in preset condition or touring automatically running status for presetting/touring automatically running status button.

(12) be the preset condition pilot lamp, represent to be in preset condition when lamp is bright, represent to be in automatically touring running status when lamp puts out.

(13) for inserting button, by this button, can insert the indicated input channel of nixie display (3) when presetting, make it participate in touring automatically operation.

(14) for rut goes out button, when presetting or in the touring automatically running status, can withdraw from the indicated input channel of nixie display (3) by this button, make it not participate in touring automatically operation.

(15) be the forward button, when presetting, can search for one by one forward the passage of all inputs; Can make traffic direction forward during touring automatically the operation.

(16) be the negative sense button, when presetting, can search for one by one backward the passage of all inputs; Automatically touring operation can make traffic direction backward.

(17) be the selection of time button, each passage that can select to participate in touring operation automatically stops the time of (conducting).Have 1.25 seconds, 2.5 seconds, 5 seconds, 10 seconds, 20 seconds, 40 seconds, selective.

Principle of work of the present utility model is: the address code that counting circuit (5) produces after the control through latch cicuit (7), makes hyperchannel switch (A) and (B) carry out channel selecting and switches output.When being in preset condition, patrol the information write store (6) of surveying operation automatically but whether each input channel needs to participate in.Automatically patrol when surveying running status when being in, match by these message levels and another level lower and decide the opportunity of counting circuit (5) upset than its frequency.

The picture of accompanying drawing is described as follows:

Fig. 1. circuit structure diagram of the present utility model.

Fig. 2. panel construction synoptic diagram of the present utility model.

The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:

As shown in Figure 1, frequency dividing circuit (1) is connected with control system (2).Control system (2) is connected with decoding monitor (4), counting circuit (5), storer (6), latch cicuit (7) respectively.Counting circuit (5) is connected with decoding monitor (4), storer (6) and latch cicuit (7) respectively again.Hyperchannel switch (A) is connected with latch cicuit (7) respectively with hyperchannel switch (B).Nixie display (3) connects with driving, drives to connect with decoding monitor (4).During operation, press power switch (10) earlier, machine enters preset condition (preset condition pilot lamp lamp is bright) automatically, at this moment, search for the passage of required monitoring one by one by forward button (15) or negative sense button (16), nixie display (3) can demonstrate the sequence number of each input channel.When the port number of required monitoring demonstrates, as press and insert button (13), then this passage is placed at once, can participate in to patrol automatically and survey operation.Go into if find misplace, can withdraw from by withdrawing from the passage that button (14) goes into misplace.After initialize operation was finished, by presetting/touring automatically running status button (11), at this moment, preset condition pilot lamp (12) extinguished, and machine then enters automatically touring state, the direction operation of its direction search when presetting.

In automatic touring operational process, can regulate forward button (15) or negative sense button (16) as required or withdraw from button (14) and change the traffic direction that patrols survey automatically and participate in the channel position that patrols survey automatically.Simultaneously, also can reinitialize by preset button (13) again and achieve the goal.

The utility model compared with prior art has following advantage:

1. whether each passage is placed monitoring state, can arbitrarily arrange.

2. when passage is arranged, can search for forward or backward successively one by one.

3. the passage that is set up can change the direction of operation at any time when automatically patrolling survey.

4. show state and automatically patrolling can carry out state and exchanges between the survey state.

5. the circuit elements device is few, and cost is low, and complete machine is in light weight, and is easy to operate.

6. the store memory cell capability is big, and input channel is convenient to dilatation.

7. can be as the Monitoring and Controlling of audiovisual reproduction, again can be as the Monitoring and Controlling of security personnel's Monitoring and Controlling, Karaoke singing-hall video reproduction Monitoring and Controlling and other side.
