り立っている。Generally, when monitoring the transmitted and received signals of a transmission device consisting of a transmitting device and a receiving device, it is difficult to determine the authenticity of the data by checking the parity code or CaC code generated by the transmitting device with the receiving device. I am a connoisseur. This conventional method is based on the premise that the checking function of the receiving device operates normally.

目的とする。Therefore, the present invention is capable of simultaneously checking the transmitted and received data of a digital transmission system for all transmitting/receiving devices at all times, as well as checking the check code generation operation of the transmitting device and the receiving device's check code generation operation. An object of the present invention is to provide a transmission system monitoring device for monitoring received data checking operations.

This signal is transmitted not only to the receiving device 22 but also to the monitoring device 26 to check the received data and code. Similarly, transmission and reception are performed between the transmitting device 13 and the receiving device 14 having the same address 2, but this signal is transmitted to the monitoring device 26 and checked. Operation timing 4 is shown, (f) is the address signal of the controller 20, (gl is the transmission data and check code of the transmitter 21, (h)
are the received data of the receiving device 22 and the check code.Similarly, 1i) is the transmitted data of the transmitting device 23, (j

If the check result of the received data of each receiving device is equal to the check result of the monitoring device, it means that the transmission system is operating normally. However, if the check result of the receiving device and the check result of the monitoring device are not equal, it is assumed that there is an abnormality in the checking operation of the receiving device or the monitoring device, or on the transmission path. .
