The controller 50 can determine whether or not an open flame occurs in the cab, whether or not the temperature in the cab is abnormal, and whether or not the air pressure in the cab is abnormal, based on the flame sensor 10, the ambient temperature sensor 20, and the air pressure sensor 30, respectively. The controller 50 determines whether to transmit the prompt message to the display 40 according to the flame sensor 10, the ambient temperature sensor 20, and the air pressure sensor 30, and the controller 50 may determine to transmit the prompt message to the display 40 when the determination result of the controller 50 includes at least one of an open flame in the cab, an abnormal temperature in the cab, and an abnormal air pressure in the cab. Specifically, in the present embodiment, the controller 50 includes a timer, and the controller 50 is configured to obtain the temperature in the cab when the open fire signal is obtained; acquiring the air pressure in the cab under the condition that the temperature in the cab is greater than a temperature threshold value; acquiring the accumulated time when the air pressure in the cab is greater than the air pressure threshold under the condition that the air pressure in the cab is greater than the air pressure threshold; sending a prompt message to the display screen 40 when the accumulated time reaches a time threshold; and sending an opening instruction to the front window opening driving device under the condition of receiving the determination instruction.
Optionally, the cab automatic safety escape control system further comprises a buzzer, the buzzer is mounted in the cab and electrically connected to the controller 50.
Specifically, when the flame sensor 10 senses that open flame combustion has occurred inside the cab, the flame sensor 10 generates an open flame signal and transmits the open flame signal to the controller 50. In the case where the open fire signal is acquired, the controller 50 immediately proceeds to the next judgment instruction (abnormality judgment of the ambient temperature sensor 20). The ambient temperature sensor 20 determines at what stage the open flame is burning, and when the sensed temperature is low, the electrical signal is low, thereby determining that the open flame is burning just now, and at this time, the controller 50 will send an instruction to the display 40 and drive the buzzer to give a buzzer alarm. When the temperature in the cab is higher than the temperature threshold, the controller 50 enters a judgment command of the next sensor (abnormality judgment of the air pressure sensor 30). When the sensing abnormality judgment of the first several stages is passed, the air pressure sensor 30 is triggered to start working, and when the air pressure changes, the open flame combustion occurring in the cab is violent and the abnormal change of the air pressure is caused. Meanwhile, after the data of the sensors in the previous stages are compared comprehensively, the timer in the controller 50 starts to accumulate the time, and after the accumulated time reaches a time threshold (for example, 1 minute), it is determined whether the fire is extinguished manually, and if the fire is extinguished, the logic judgment of the controller 50 is not true, and no prompt message is sent to the display screen 40. If the condition is still met, the fire source still continues to burn, at this time, the controller 50 sends prompt information to the display screen 40, the display screen 40 sends an emergency prompt and gives a buzzer alarm along with the buzzer, whether the escape system is started or not is prompted by red flashing, a driver can select to start the escape system through touch operation of the display screen 40, and the display screen 40 can generate a determination instruction based on user operation and send the determination instruction to the controller 50. The controller 50, upon receiving the determination command, sends an opening command to the front window opening drive device to open the front window of the cab. Alternatively, in the present embodiment, the front window opening driving device includes a front window lift motor 72 and a winding mechanism; the front window lifting motor 72 is in power coupling connection with the hoisting mechanism, and the front window lifting motor 72 is electrically connected with the controller 50; the extending end of a hoisting steel wire of the hoisting mechanism is connected with the front window. The controller 50 will send an instruction to the front window lifting motor 72, and the front window lifting motor 72 will drive the winding mechanism to rotate rapidly, so as to pull the front window glass to rise, and the driver can escape from the opened front window directly.
Alternatively, in the present embodiment, the controller 50 acquires the air pressure in the cab in a case where the temperature in the cab is less than the temperature threshold and the accumulated time during which the open flame signal is acquired reaches the preset time.
Specifically, the electric signal emitted when the temperature sensed by the ambient temperature sensor 20 is low, and it is determined that open flame combustion is in a state of just occurring. The controller 50 may enter the abnormal judgment of the air pressure sensor 30 if the open fire signal is detected after a continuous preset time (for example, 3 minutes) since the open fire is just generated, and the manual extinguishing may be performed.
As shown in fig. 1 and 2, in the present embodiment, the automatic safety escape control system for a cab further includes a gas sensor 60, wherein the gas sensor 60 is installed in the cab and electrically connected to the controller 50; the gas sensor 60 is used for detecting the concentration of preset abnormal gas in the cab; the controller 50 is also configured to acquire an open flame signal in a case where the concentration of the preset abnormal gas in the cab is greater than the concentration threshold.
Specifically, in some engineering machinery cabs with long service life, a short circuit of a line is likely to occur due to a driver's private change or due to an abnormal aging of the line. In the short circuit, a small range of skin rubber is melted by heat and abnormal gas is released at the same time, at this time, the gas sensor 60 preferentially catches the abnormality, and when the concentration of the abnormal gas in the cab is greater than the concentration threshold, the controller 50 immediately enters the next judgment instruction (the flame sensor 10 judges the abnormality). At this time, if the flame sensor 10 does not sense the occurrence of an open flame inside the cab, it means that no open flame has occurred temporarily in the high-temperature melting stage. Then a signal is sent to the display screen 40 through the controller 50, and the display screen 40 gives an alarm to indicate that there is a possible tendency of spontaneous combustion, and the driver is asked to pay attention to whether there is a safety hazard of spontaneous combustion around.
