FR2481827A1 - Monitoring desk for operation of several devices - contains microprocessor to provide control and to operate fault alarm systems - Google Patents

Abstract

The operation of a number of equipments is monitored from a monitoring desk or dashboard which does not require constant attendance by an operator. An audible alarm is operated if a fault occurs. Information from different equipments is grouped together and applied to grating circuits to which a flashing signalling lamp is connected to provide visible indication of a fault condition. A loudspeaker operated discontinuously with a particular frequency provides an audible alarm. A second grating circuit provides second visible and audible alarms operating at a different frequency. Operation and control of the monitoring desk is provided through a keyboard and microprocessor to which the equipments are connected and from which the alarms are operated.

Description

 The present invention relates to a self-monitoring system of information from various equipment, this information being received on an observation device such as, in particular, a desk, a console, a dashboard, etc. .

It is known that, in a number of technical fields, there are currently automatic surveillance systems or self-monitoring systems that exempt the user, for example a monitoring agent, from making an observation. permanent information and / or signals received on an observation means such as a dashboard or a desk.

 In equipment operation monitoring systems, there are two types of information that appear on the console or dashboard: operating information, and fault information. Generally, each information corresponds to a signaling (such as a light). Thus, in a surveillance system applied to an automobile dashboard, a fault in oil pressure results in the lighting of a corresponding indicator.

 The known surveillance systems have the disadvantage of requiring the user to be present in front of the desk or the dashboard, and to observe it to see the information given to it. As a result, its range of action to undertake ancillary work is very limited.

 The present invention proposes to provide an improved self-monitoring system which has the originality of combining several signals, to create a real self-monitoring system around an information center.

 The self-monitoring system according to the present invention is characterized in that all the information is centralized, and in that it triggers a sound signaling when one or more malfunctions occur. When the console, console or dashboard is complex and receives a lot of information, these are grouped together, by equipment or by function. A command button makes it possible to self-monitor the information of the grouped equipment in the corresponding subset, the signaling of each subset being done using a lamp incorporated in the command button.

- light off: no self-monitoring
- light on (continuous): self-monitoring
- light on (discontinuous): the incident is in the group
information of the subset
considered.

 Finally, for each information, according to the invention, there is provided signaling.

 The self-monitoring system according to the invention can in particular be applied to a remote operating console, without being limited to this particular application.

According to an exemplary embodiment of a self-monitoring system according to the present invention, it is characterized in that it comprises - a keypad, in which each key comprises a light in
body, the depressed position of a certain key controlling the
self-monitoring information from the equipment concerned - a first alarm, signaling a fault by the pre
presence of at least one fault information on the desk, this first
an alarm including visual information such as a flashing light,
and a sound information by speaker, giving a discontinuous signal
on a first frequency F1 - a second alarm, constituted in the same way as the first, but
giving sound information in the form of a signal according to a
conde frequency F2, this second alarm signaling a fault from the ab
at least one piece of information; and, manually operated means, suppressing audible alarms.

 According to a characteristic of this invention, the circuit of the first alarm comprises an integrated circuit - OR gate whose inputs are attacked by the fault information, the output of this gate always being a logic 1 when at least one input variable is 1 , this state ensuring the triggering of the alarm.

According to another characteristic of this invention, the circuit of the second alarm comprises NAND / ET integrated circuits receiving the equipment-grouped operating information, the self-monitoring setting giving a logic level 1 to the control input of the NAND / AND gate considered, and the output of this gate being a logical O when all the states of the inputs of the gate are at level 1. The outputs of the AND gates
NO / AND attack an integrated circuit OR whose output is 1 when at least one input variable is 1, thus ensuring by this state the triggering of the alarm.

 According to another characteristic of this invention, the audible and visual signaling devices of the alarms comprise a clock oscillator giving, in power output, a 1 Hz rectangular signal when it is triggered by the state 1 of the OR gate, this voltage discontinuously illuminating a light emitting diode used as a light indicator and supplying at an alternating rate an oscillator emitting an audible frequency F1 or F2.

 According to yet another characteristic of this invention, the visual signaling device of the second alarm comprises: a flip-flop (JK), an input (J) of which is at logic level 1 when the control input of the NAND integrated circuit / AND is at level 1; a clock oscillator providing a rectangular signal of 1 Hz, which drives the input (H) of the flip-flop, whose input (K) is driven by the output of the NAND circuit / "T, and a light-emitting diode which is powered through the flip-flop, the illumination of this diode being continuous when the self-monitoring of the equipment is controlled and there is no fault, or discontinuous at the rate of the clock if a fault occurs.

As indicated above, a command button makes it possible to self-monitor the information of the equipment grouped in the corresponding subset. As indicated in the drawing, the signaling of each subassembly is effected by an indicator incorporated in the control button, according to the following principle - light extinguished

the operating incident is
found in the informa group
of the subset considered.

 Finally, each piece of information has a particular signage.

 Referring now to Figures 2 to 6, which illustrate a first example of non-limiting application of the self-monitoring system according to the invention to a tele-operating console of a broadcast network.

 This desk (Fig. 2) makes it possible to give orders to different equipments; it informs by visualization of the state in which these equipments are, and it allows the control of the modulations sound and / or image + sound, by comparing the modulations departures with the demodulated returns and the modulations coming from the direct reception HF. This desk comprises, at A, the self-monitoring system according to this invention. The front of this system A has been shown on a larger scale in Figure 3.

As stated above, the self-monitoring system of the desk dispenses the monitoring agent of a permanent observation of the signals, and allows him to undertake ancillary work. This system, inserted between the radio listening device and that of the links with the transmitting centers on the desk, includes; a keyboard with keys 10; each of the keys 12 of this keyboard has
an incorporated light; the depressed position of such a command key
the self-monitoring of information from the equipment concerned - a first alarm, referred to as "alarm 1" on the drawing.
consists of visual information, produced in the form of a
flashing light 14, and sound information, obtained by the intermediate
diapre of a speaker 16, emitting a discontinuous signal on a pre
first frequency F1 - a second alarm, indicated "alarm 2" on the drawing. This one is
constituted in the same way as the first alarm. She understands
therefore a flashing light 14 'and a loudspeaker 16'. The frequency of
the information is F2; and, two pushbuttons 18, 18 'deleting, in the depressed position, the
sound alarms.

 According to the invention, the first alarm ensures the signaling of a fault by the presence of at least one fault information on the desk, and the second alarm signals a fault resulting from the absence of at least one step information.

 We will now describe, with reference to Figures 3a and 3b, the operating principle of the first alarm.

 All the information indicating a fault attacks, through interfaces I necessary to adapt the logic levels1 inputs x0, xl, x2 .. x of an integrated circuit - OR gate. The output y of this gate is always 1 when at least one input variable is l. By this state, it ensures, through another interface device I, the triggering of the alarm (output y).

 Figures 4a and 4b illustrate the principle of operation in static logic of the second alarm. All the operating information arrives, via I interfaces, on NAND / ET integrated circuits, the information being grouped by equipment (X, etc.).

G
To put a device in self-monitoring, the user presses the corresponding key 12 of the keyboard 10. This key gives a logic level 1 to the input x0 of the NAND gate AND. The output y of this gate is a logic 0 when all the states of the inputs x1, x ... x are at level 1. The outputs y of the NAND / AND gates attack an integrated circuit gate OR. The output Y of this gate is 1 when at least one input variable is 1. By this state, the OR gate triggers the alarm.

 In the appendix to the present description, the respective synoptic diagrams of the signaling of a fault by the first and second alarms have been given in the form of tables I and II, the alarm 1 signaling the fault by the presence of at least a fault information, and the alarm 2 signaling a fault by absence of at least one information running.

 Referring now to Figure 5, which shows the diagram of the audible and visual signaling device of alarms 1 and 2. The devices are identical for the two alarms, only being different the tones of audio-frequency information (F1 and F2).

 The state 1 of the OR gate triggers a clock oscillator 20, giving, at the power output, a rectangular signal of 1 Hz. This voltage lights discontinuously a light emitting diode 22, used as a light indicator. (Indicators 14, 14 ', Figure 3), and it feeds at an alternating rate a low frequency oscillator 26 emitting an audible frequency (F1 or F2). This signal, amplified in a low frequency amplifier 28, outputs through the speaker 16 (or 16 ', in the case of the alarm 2).

The push-button contact rest 18 (18 'in the case of the alarm 2), makes it possible to block the supply of the oscillator 26, in order to suppress the sound signaling.

 The operation of the visual signaling device of the second alarm will now be described.

Equipment (X, etc.) is self-monitored in
Pressing the pushbutton - corresponding work contact 12 of the keyboard 10.

This gives a logical level 1 to the control input x 0 of the integrated NAND / ET circuit, and to the input J of a flip-flop 34. The state of the second input K depends on the logic level of the exit y from the door NO
AND / ET. A clock oscillator 32, providing a rectangular signal of 1 Hz, attacks the input H of this terminal 34.

The truth table of the rocker 34 is the following

<tb> J <SEP> K <SEP> O <SEP>
<tb> 0 <SEP> O <SEP> Q <SEP> ne <SEP> change <SEP> not.

<tb><SEP> to <SEP> to <SEP> each <SEP> hit <SEP> clock <SEP> 32.
<Tb>

The operating principle is as follows
A light-emitting diode 30, incorporated in the push-button 12, is fed through the flip-flop 34. Q triggers the supply of the diode 30, via a transistor T. As a result, the lighting of this diode is continuous when the self-monitoring of the equipment is commanded and there are no reported faults (J = 1, K = 0 Q a = 1) or discontinuous at the clock rate, if a defect appears (J = 1; K = 1
Q passes alternately from 1 to 0 at each clock stroke).

 The application, described above, of the self-monitoring system according to the invention to a tele-operating console of a broadcast network is in no way limiting. As an example of another possible application, FIG. 7 represents a diagram of a self-monitoring system comprising a sound signaling supplementing the visual signals of a dashboard of a car.

 The operating principle of this system is identical to that described above. When the output y of the OR gate is an O, no alarm is emitted, and when this output is 1, the alarm is triggered by the transmission of a discontinuous rhythm audio-frequency (1 or Z Hz ), as described above with reference to Figure 5.

The table below illustrates the operating principle of this system.

Of course, the information triggering the alarm may be variable, depending on whether the model of the vehicle is more or less sophisticated.

Various variants of this invention can be envisaged. It is known that a simple logic function corresponds to a function lo.
complementary strategy. So, an OR gate can be considered
as a NOR circuit followed by an inverter, or as many inverters as there are input variables (I.'O, x2 .0. x xn),
followed by a NAND circuit An identical reasoning, put in
obvious by Boolean algebra and truth tables, applies
to AND, NAND, and NAND functions. Therefore, in the
self-monitoring system according to the invention, the NAND gates /
AND and OR can be replaced by other doors, next
the complementarity of logical AND functions; NAND; OR
NO, OR, NO.

2 "- the information center whose synoptic diagram has been represented
in Figure 1 can be standardized in its manufacture in order to
see being used with different equipment, the surplus of
trés and subsets remaining free in some cases.

This is how the information center and the complete circuits
can be made using printed circuit boards and
cables, or even using a single integrated circuit (
semiconductor), or a single hybrid circuit (insulating substrate) com
carrying doors, clocks, scales, amplifiers,
etc. , or in juxtaposed slices.
