After receiving the RS232 signal converted by the serial server 202, the fire door control board 209 performs complex logical operation processing, and controls opening or closing of fire prevention according to the analyzed command.
The application also provides a self-checking method of the tunnel fireproof door, based on the tunnel fireproof door, the specific technical scheme is as follows:
s101: after the tunnel fireproof door is powered on, the fireproof door control board sends an opening instruction; the tunnel fireproof door comprises a first side door and a second side door;
s102: after the tunnel fireproof door receives the opening instruction, the first side door is opened by a first preset angle, and then the tunnel fireproof door returns to the first opening time;
s103: after the first side door is opened, the second side door is opened by a second preset angle and returns to the second opening time;
s104: after the first side door and the second side door are both opened, the fireproof door control board delays the preset time and sends a closing instruction;
s105: the second side door is closed by a second preset angle and returns to the first closing time;
s106: the first side door is closed by a first preset angle and returns to the second closing time;
s107: if any one of the first opening time, the second opening time, the first closing time and the second closing time exceeds a corresponding preset time threshold value, the tunnel fireproof door has a fault.
It should be noted that, no matter which side door fails to open or opens slowly, its corresponding opening time exceeds the preset time threshold. The first opening time, the second opening time, the first closing time, and the second closing time refer to the time required to open or close the side door. In the self-checking process, because the crack department of left side door and right side door probably designs into fire-retardant type usually, the inboard edge of a certain side door can extend a section distance promptly for the in-process of opening the door can only open another side door earlier, and at the in-process of closing the door, this side door must be closed earlier simultaneously. The inner side edge means an inner side in the side door closing direction. Therefore, in the self-checking process, the first side door is opened firstly, then the second side door is opened, then the second side door is closed firstly, and then the first side door is closed. That is, the memory edge of the second side door has a tab. Of course, the sheet-like projection can improve the fire retardant effect whether the left door or the right door is designed.
In addition, the first preset angle and the second preset angle may be the same or different, and are not limited specifically herein.
The application also provides a tunnel fire prevention method, based on the tunnel fire door, the specific technical scheme is as follows:

After the tunnel detection robot 1 passes through the tunnel fireproof door, a door closing instruction is sent through an internal wireless network bridge. The wireless bridge 4 on the power communication box 3 receives a door closing instruction sent by the tunnel inspection robot 1, the door closing instruction is forwarded to the serial server 202 through the switch 304, and the serial server 202 converts a network signal into an RS232 signal and sends the RS232 signal to a communication serial port of the fireproof door control board 209. The fireproof door control board 209 analyzes and issues a door closing instruction, and first sends a control command to the left motor drive board 211 to drive the left door opening motor 213 to drive the left door of the fireproof door to close. When the closing angle is 15 degrees, a door closing instruction is sent to the right motor driving board 212, and the right door opening motor 214 is driven to drive the right door of the fireproof door to close. After the left door 203 and the right door 208 of the tunnel fireproof door 2 are obtained to be closed in place through information acquisition and servo control of the left door motor encoder 215, the right door motor encoder 216, the left door position sensor 217, the right door position sensor 218, the left door limit switch 219 and the right door limit switch 220, the fireproof door control board 209 sends in-place information to the tunnel detection robot 1 through the wireless network bridge 4, informs the tunnel detection robot 1 to move forwards continuously, and completes a set inspection task.
