the dry contact signal monitoring unit 301 is configured to monitor a signal of an external dry contact of the relay device in real time, and generate a corresponding control instruction to the data receiving unit 302 according to a configuration parameter when detecting a trigger signal of the external dry contact, so as to control a state of a corresponding relay, such as actuation or disconnection, according to a control protocol of the external dry contact and a user configuration parameter. Assuming that one dry contact corresponds to the first relay and the second relay, the dry contact is actuated when pressed and corresponds to the first relay and the second relay being open, and the dry contact is actuated when popped and corresponds to the first relay and the second relay being open, and the corresponding relationship and the control mode between each dry contact and the relay are preset by configuration parameter data, the dry contact signal monitoring unit 301 generates a corresponding control instruction to the data receiving unit 302 according to the real-time monitoring signal of the external dry contact and the configuration parameters.
In the invention, a certain dry contact CAN be configured into an emergency mode switch through the parameter configuration unit 302, when the dry contact signal monitoring unit 301 monitors that the signal of the dry contact is triggered, namely the emergency mode is triggered, a trigger control instruction of the emergency mode is generated to the data receiving unit 303, and after the trigger control instruction is analyzed by the data analyzing unit 304, a complete closing instruction is broadcasted to terminal equipment on the whole Bus through the CAN-Bus and the RS485 Bus, namely all the terminal equipment is in a closed state. In order to ensure that broadcast data in the main contact emergency mode can be broadcast to each terminal device of the whole system, the adjacent relay can start the relay function to help forward the 'full-off' instruction, that is, when one device broadcasts the full-off instruction, the node adjacent to the relay function can serve as the relay to help broadcast the full-off instruction again, and the devices on the bus can respond. .

In the embodiment of the present invention, the relay device includes 8 relays, which can be externally connected with 10 external trunk contacts, the type of the device controlled by each relay, and which relay corresponds to each external trunk contact (one trunk contact may correspond to one relay, or one trunk contact may correspond to multiple relays) are all distinguished by configuration parameters and configured by the parameter configuration unit 302, and when the device receives a control instruction sent from an upper layer, the device analyzes which relay is targeted, then extracts configuration data of the relay, and determines how to control each relay by combining the two.

In order to ensure that the device can accurately receive the control instruction issued by the upper main control, each complete protocol instruction is cached into the RBUFFER to generate a circular cache queue, and then the data is analyzed and processed by the protocol analysis process of the data analysis unit 304.
And the data analysis unit 304 is configured to analyze the message instruction in the message queue according to the message queue and according to the configuration parameter, and transmit the result to the relay channel control module 305. Specifically, the data analysis unit 304 obtains the protocol command or the control command generated by the dry contact signal monitoring unit from the message queue, analyzes according to the corresponding configuration parameter, and sends the analysis result to the relay channel control module 305.

That is, the message response module 306 generates a corresponding response message protocol according to the control result of the relay channel control module 305, and feeds back the response message protocol to the master control through the Can-Bus and the RS485, that is, the status of each relay is fed back to the master control through the Can-Bus and the RS485 Bus to synchronize the status. In the embodiment of the present invention, in order to ensure that the master control states are synchronized timely, the message response module 306 feeds back the state synchronization packet and the associated device information contained in the relay state message.
Preferably, the business operation layer 30 further includes:
and a key signal monitoring unit 307, configured to monitor each physical key signal corresponding to each relay, generate a corresponding control instruction, and submit the control instruction to the data receiving unit 303.

That is, in the present invention, the message command received by the data receiving unit not only includes a protocol command issued by the upper layer master through the CAN-Bus and RS485 Bus, but also includes a control instruction generated by the trunk node signal monitoring unit according to the configuration parameters when detecting the trigger signal of the external trunk node, and a control instruction generated by the key signal monitoring unit 307 monitoring each physical key signal, and is cached in the message queue.
That is, in the present invention, there are multiple operation modes for the relay, and in order to ensure that the multiple operation modes are not in conflict, the present invention may assign different priorities to the various operation modes in advance, in a specific embodiment of the present invention, the priority of the physical key of each relay is the highest, then the external dry contact, then the CAN-Bus control protocol instruction, and finally the RS485 control protocol instruction, but the present invention is not limited thereto.
