Abstract

PURPOSE:To simply realize a wiring for executing an interruption by a sensitive signal from a sensor at a low cost by forcibly switching the picture signal of a necessary telecamera correspondingly to the detecting signal of the sensor and regardless of the control signal of an operation device. CONSTITUTION:When a sensor 54 is an OFF-state, a control command at an operation device 41 is transmitted through control signal lines 42 and 43 to controllers 44 and 45, and a desired picture can be supervised on a monitor TV 56 by controlling telecameras 46 and 47 and output switching devices 50 and 51. Further, when the sensor 54 becomes an ON-state, since data to inform of the ON-state are outputted from the sensor 54 through a signal line 55 to the control signal lines 42 and 43, and the data are transmitted to the operation device 41 and the controller 44 and 45, the picture signal can be forcibly switched independently of the control state of the operation device 41. Thus, the wirings between the operation device 41 and the controllers 44 and 45 can be successively connected in a bus shape, and the wirings can be easier.

And this TV left camera 6. The image signals from If are transmitted to the image signal switching device 20 via the image transmission lines 1g and 19 such as coaxial cables, and the switching device 2o is controlled to switch under the control from the operating device 11 to display the image signals on the monitor TV 21. #I was monitoring JgR. Further, the signal from the sensor 22 is input to the switch 2° via the sensor signal transmission path 23. sensor 22
is turned on, forcibly controls the switch 20,
I watched the image signal on monitor TV'21'.

According to the above configuration, the control device 11 and the remote controllers 14 and 15 are individually controlled by the control signal 81291.
3 and image transmission lines 18 and 19, it is also necessary to install another 11823 for transmitting the sensor signal to the switch 20, and as a result, a lot of wiring work is required. However, the disadvantage was that the cost was high.

Therefore, as shown in FIG. 7, the operating device 24 and the controller 25.
26 are connected by a bus-like control signal line 27, and output switchers 28, 29 are provided on the controller 25, 26 side, and the H controller 25

In this way, between the operating device 24 and the controllers 25 and 26, only the control signal line 27 and the image transmission line 33 need be connected in sequence. However, in this configuration, in order to control the switching of the image signal based on the sensing signal from the sensor 34, a control signal line "
35 and 36 were required to be connected individually.

As described above, in the configuration shown in FIG. 7, the arrangement between the operating device 24 and the controllers 25 and 25 and 26 becomes easy, but on the other hand,
Wiring 35.36 from the sensor 34 to the output switch 28.29'' is required, which complicates the wiring work and increases cost.

Irrespective of this, the required image signal of the television camera is forcibly switched and sent to the monitor television.

[Embodiments of the invention]

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

FIG. 1 shows its configuration, where 41 is an operating device, 42.
43 is the control signal line, 44.45 is the controller, 46.47 is the nine TV camera mounted on the back white 48.49, 50.51
52 and 53 are image transmission paths, 54 are sensors, 55 are signal lines, and 56 are monitor TVs.

The operation a41 and the controllers 44, 45 are connected by control signal lines 42, 43 configured in the form of a bus, and control signals output from the operator 4 are sent to the controllers 44, 45. The controllers 44, 45 control the TV cameras 46, 47 mounted on the receivers 48, 49 according to the sent control signals, and obtain image signals. This image signal is sent to output switching devices 50 and 51. The output switch 50.51 and the monitor TV 56 are connected by an image transmission path 52.53 configured in the form of a bus.
The image signal from is sent to the monitor TV 56 via the image transmission paths 52 and 53, and the image is displayed. Further, the signal line 53 for transmitting the detection signal of the sensor 54 for guarding against intruders etc. is connected to the bus-shaped control signal R42e.
43.

With the above configuration, when the sensor 54 is in the OFF state, the control command from the operating device 41 is the control signal llI42, 4
3 to the city controllers 44, 45 I/C to control the TV camera 45, 47 and output switch 50, 51.
A desired image can be monitored on the monitor TV 56. Further, when the sensor 54 is in the on state, data indicating the on state is output from the sensor 54 to the control signal Mi42o4s via the signal @55, and the controller 41 and the controller 4
When transmitted via 4°45 I/C, the image signal can be forcibly switched independently of the control state of the controller 4.

Next, the operation of the above embodiment will be explained.

FIG. 2 shows an off state in which the sensor 54 is not in a sensing state, and at this time the operating device 41 is connected to the two controllers 44.

Further, FIG. 3 shows a case where the sensor 54 is in the sensing state (on), and the sensor 54 is controlled via the signal &I55 regardless of the output state of the operating device 41 shown in FIG. 3(a) Ic. Data ``D'' indicating the sensing state is output on the signals +1!42.43 as shown in FIG. 3(c). The data "1" and "2" output from the controller 41 and the data "9"D# output from the sensor 54 collide on the control signal lines 42 and 43 as shown in FIG. 3(d), resulting in a data error. . Therefore, the output data and input data are compared using the operation device 41, and if there is a difference in the data, the operation device output is

Subsequently, FIG. 4 shows that the control data is output from the operating device 41 intermittently as shown in FIG.
When the sensor 54 is in the detection state as shown in Fig. 4(b), the sensor 54 detects an empty space on the control signal line 42, 43, and during that period, data indicating the detection state as shown in Fig. 4(c) K is generated. ``D'' is output. As a result, the detection signal can be transmitted without causing data collision as shown in FIG. 1X4 (d). Moreover, control information can also be transmitted from the operating device 4 to the controllers 44 and 45 while transmitting the detection signal.

As shown in FIG. 5, while the controller 4 is busy transmitting response data @A'' in response to the detection signal "D" from the sensor 54, the sensor 54 continues to transmit the detection signal while in the detection state. , control signal line 4; t, 43 may be prevented from being occupied.

According to the more detailed configuration shown above, the operating device 41, the controllers 44, 45, and the sensor 54 are sequentially connected in a bus-like manner, and
