Abstract

PURPOSE:To omit the external device which sets the take-in position of a signal by providing each signal processor with the means which shifts the signal, which is not taken into the processor itself, in the processor and sends it to the following signal processor in accordance with the start position of time division multiplexed signals. CONSTITUTION:Time division multiplexed signals 31 are sent to a signal processor 21 from a controller 1. The signal processor 21 takes in signals, whose number is determined, from the start of time division multiplexed signals 31. Taken-in signals are processed in the signal processor 21, and the other signals are shifted in the signal processor 21 and are moved to the start position of time division multiplexed signals. They are sent as time division multiplexed signals 32 to a signal processor 22 in the following stage. Hereafter, the same processing is performed in signal processors 22, 23,...2n. Thus, it is unnecessary to change setting from the external though the number of signals to be taken into each signal processor is increased or reduced.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a signal processing system that processes one-time division multiplexed signals, and more specifically, a control device in which a plurality of signal processing devices are connected to a control device. The present invention relates to a signal processing system configured such that each signal processing device sequentially receives a time division multiplexed signal sent out by a device.

(Prior Art) FIG. 4 is a block diagram showing an example of a conventional signal processing system that processes a one-time division multiplexed signal.

Time division multiplexed signal 3 from control device l to signal processing device 21
is being sent.

The signal processing device 21 sends the 5 time division multiplexed signal 3t as it is to the lower signal processing device 22, and at the same time, the signal processing device 21 sends the 5 time division multiplexed signal 3t as it is to the lower signal processing device 22, and at the same time receives the continuous signal from the position specified by the acquisition position setting device 71 in the time division multiplexed signal 3. Import into own device. Time division multiplexed signal 3
flows to the lower level signal processing device, and the signal processing device 22
．． 23,...2n also have n intake level child setting device f172.73. ......Receive continuous signals from the position indicated by 7n into the own device.

FIG. 5 shows how to take in signals when all the take-in position setting devices are set so that the take-in signals of each signal processing device are continuous in the 1-hour side line weighted signal 3.

(Problem to be Solved by the Invention) In the conventional signal processing system that performs all the processing of time-division multiplexed signals, the signal acquisition position is set for each signal processing device in this way. There is a drawback that if the number increases or decreases, all settings of the intake position setting device must be changed. Further, even when changing the connection order of signal processing devices having different numbers of signals to be captured, the settings of the capturing position setting device have to be changed, so there is a drawback of lack of flexibility.

An object of the present invention is to solve the above-mentioned drawbacks, and to provide an entire signal processing system that does not require any external setting changes even when the number of signals acquired by each signal processing device increases or decreases.

(Means for Solving the Problems) In order to achieve all of the above objects, a signal processing system according to the present invention connects a plurality of decoding processing devices to a control device for all series, and processes the time division multiplexed signals sent out by the control device. In a system configured such that the plurality of signal processing devices sequentially capture a plurality of continuous signals, each of the signal processing devices receives the number of signals that it should capture from the previous device in a time-sharing manner. It has an acquisition means that continuously acquires the multiplexed signal from the beginning, and a means that moves the signal that is not acquired by the own device by the position tt to the beginning of the time division multiplexed signal and sends it to the subsequent device. has been completed.

(Example) The present invention will be explained in more detail below with reference to one drawing.

FIG. 1 is a block diagram showing an embodiment of a signal processing system according to the present invention.

The time division multiplexed signal 31 from the control device 1 is sent to the signal processing device 2.
Send to 1 and insert. The signal processing device IL21 takes in the number of signals to be taken in from the beginning of the time division multiplexed signal 31.

The captured signals are processed within the fs signal processing device 21, and the remaining signals that have not been captured are internally shifted and moved to the leading position of the time division multiplexed signal. The signal is then sent to the subsequent signal processing device 22 as a time division multiplexed signal 32. below.

Signal processing devices 22, 23. . . . Similar operation is performed for 2n.

FIG. 2 is a diagram showing details of the internal configuration of the signal processing device 2- in FIG. 1.

Time division multiplexed signal 3 from the previous stage signal processing device 2i-1
The leading portion of - is shifted to shift register No. 6 n, and further shifted to a shift register 51 having a capacity that cancels out the number of signals to be taken in n. As a result, the remaining portion is written to the shift register 6i, which has a full capacity corresponding to the number of signals that are not taken in. The signal written to the shift register 5s is processed by the signal processing section 4-.

The signal written in the shift register 64 is sent to the lower signal processing device No. 2+1 as a time division multiplexed signal 3i+1 in accordance with the leading position of the 1 time division multiplexed signal.

Figure 3 shows time division multiplexed signals 31, 3 between each signal processing device.

(Effects of the Invention) As explained above, the present invention enables each signal processing device to shift all the signals that are not taken in by the device itself and to match the start position of the time division multiplexed signal to the subsequent signal processing. The means of delivery to the device is gold-plated. Therefore, an external device for setting the signal acquisition position f can be omitted, and even if there is an increase or decrease in the etic acquisition signal of each signal processing device, there is no need to change the settings of other signal processing devices. There is.
