Detailed Description
To make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention are combined to clearly and completely describe the technical solutions of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
The controller resetting device and the working machine according to the present invention will be described with reference to fig. 1 to 2.
Fig. 1 is a schematic structural diagram of a controller resetting device according to an embodiment of the present invention.
As shown in fig. 1, the present embodiment provides a controller resetting device, which includes: the reset component 1, the controller 2 and the watchdog component 3; the reset component 1 is respectively connected with the controller 2 and the watchdog component 3, and the watchdog component 3 is connected with a reset pin of the controller 2; the reset component 1 is used for detecting the fault information of the controller 2, and the reset component 1 is also used for receiving a reset operation signal of an operator and triggering the watchdog component 3 to reset the controller 2. The controller 2 may be the controller 2 of various working machines as the object to be reset in the present embodiment, and may be, for example, the controller 2 of an excavator, the controller 2 of a crane, or the like. The fault information includes a fault such as a crash.
In a specific implementation process, an excavator is taken as an example for description, and since the excavator controller 2 is packaged in a box body, a soft reset mode is mostly adopted for resetting the controller 2 when the controller 2 fails, that is, the controller 2 can be reset in a software mode without opening the box body, so that fault maintenance is facilitated. As shown in fig. 1, the reset component 1, the controller 2 and the watchdog component 3 are respectively in communication connection with the CAN bus, so that mutual communication data interaction CAN be realized among the reset component 1, the controller 2 and the watchdog component 3. The watchdog component 3 may be a watchdog timing circuit or a watchdog timing chip.
The controller 2 is connected to the reset component 1, so that the reset component 1 can detect whether the controller 2 has a fault, for example, the reset component 1 can detect an electrical signal sent by the controller 2 at regular intervals, after the controller 2 has a fault, the reset component 1 cannot detect the electrical signal of the controller 2 within a corresponding time, that is, the reset component 1 and the controller 2 are disconnected, and therefore, after the reset component 1 cannot detect the electrical signal of the controller 2, it can be determined that the controller 2 has a fault. At this moment, alright send the warning suggestion, for example CAN be audible and visual alarm's mode to suggestion operator current controller 2 has taken place the trouble, the operator is after carrying out the fault detection investigation, alright with the operation that resets to subassembly 1, then subassembly 1 that resets just CAN produce the operating signal that resets, the subassembly that resets just CAN be through CAN bus with the operating signal that resets send watchdog subassembly 3 to, watchdog subassembly 3 just is triggered, thereby watchdog subassembly 3 triggers controller 2 and accomplishes and resets.
For example, the reset assembly 1 may be provided with two states, one being a state in which only data can be received but not operated, and one being a state in which operation is possible. When the controller 2 works normally, a signal connection is established between the controller 2 and the reset assembly 1, so that the reset assembly 1 can normally receive an electric signal of the controller 2, and the reset assembly 1 cannot operate at the moment, namely the watchdog assembly 3 cannot be triggered through the reset assembly 1 at the moment. Only after controller 2 breaks down, reset assembly 1 can not normally receive controller 2's signal of telecommunication, and reset assembly 1 at this moment just can operate, and the operator alright trigger the action of watchdog subassembly 3 through reset assembly 1 to the realization is to resetting of controller 2. That is, only after the controller 2 fails, the operator can perform the reset operation on the controller 2, thereby ensuring the safety of the reset. The controller 2 can not be reset under the condition of no fault, and the problem that the controller 2 generates continuous automatic reset due to other faults such as sudden interruption and the like is avoided.
The utility model provides a pair of controller resetting means, include: the reset component 1, the controller 2 and the watchdog component 3; the reset component 1 is respectively connected with the controller 2 and the watchdog component 3, and the watchdog component 3 is connected with a reset pin of the controller 2; reset assembly 1 is used for detecting the fault information of controller 2, reset assembly 1 still is used for receiving operator's reset operation signal to trigger watchdog assembly 3 reset controller 2, because watchdog assembly 3 whether triggers controller 2 to reset receives reset assembly 1's control, and only after reset assembly 1 received operator's reset operation signal, reset assembly 1 can trigger watchdog assembly 3 to reset controller 2, continuous reset problem when having solved controller 2 trouble effectively.
Fig. 2 is a second schematic structural diagram of a controller resetting device according to an embodiment of the present invention.
Further, on the basis of the above-mentioned embodiment, as shown in fig. 2, the controller resetting device in this embodiment, the resetting assembly 1 includes: a detection assembly and switch 12; the detection component is connected with the controller 2, and the switch 12 is respectively connected with the watchdog component 3 and the detection component; the detection component is used for detecting the fault information of the controller 2, and the switch 12 is used for receiving a reset operation signal of an operator and triggering the watchdog component 3 to reset the controller 2.
Wherein, the detection component can include: a display 11; the display 11 is connected to the controller 2 and the switch 12, respectively, and the display 11 is used for detecting the failure information of the controller 2. The display 11 is connected with the heartbeat of the controller 2; the display 11 is used to receive the heartbeat signal of the controller 2. The switch 12 includes virtual keys; the virtual key is arranged on the display 11, the virtual key is respectively connected with the display 11 and the watchdog component 3, and the virtual key is used for triggering the watchdog component 3 to reset the controller 2.
Specifically, the display 11 and the controller 2 are connected in a heartbeat communication manner, and the heartbeat mechanism is a mechanism that sends a signal pulse at a fixed time to enable the other party to determine the normal state of the other party so as to ensure the connection effectiveness. That is, the controller 2 sends a pulse signal to the display 11 at a timing such that the display 11 receives the signal to indicate that the controller 2 is in a normal state, for example, 40 times a minute, and when the display 11 fails to receive the signal sent by the controller 2 within a preset time interval, the controller 2 is in a fault state.
After detecting that the controller 2 has failed, the display 11 at this time controls the virtual key to be valid, that is, the virtual key changes to color, and the virtual key at this time can control the watchdog component 3 to trigger the controller 2 to reset. The two states of the virtual key are determined normally through the fault of the controller 2, namely when the controller 2 is normal, the virtual key is in a grey state, and even if the virtual key in the grey state is operated, the virtual key cannot trigger the action of the watchdog component 3. Only after the display 11 detects the failure of the controller 2, the virtual key is valid, and in the color state, the virtual key in the color state can be controlled, so that the controller 2 can be reset through the virtual key in the color state.
The whole process is that the display 11, the virtual keys, the controller 2 and the watchdog component 3 are all in communication connection with the CAN bus, so that communication CAN be carried out among the display, the virtual keys, the controller 2 and the watchdog component 3. And a heartbeat communication connection is also established between the controller 2 and the display 11, the heartbeat communication connection is used for sending a signal to the display 11 by the controller 2 based on a heartbeat mechanism, and the display 11 indicates that the controller 2 is normal as long as the signal sent by the controller 2 can be received by the display 11. When the display 11 cannot receive the signal sent by the controller 2, it indicates that the controller 2 at this time is malfunctioning. When the controller 2 is normal, the virtual key is in an invalid state, when the controller 2 fails, the virtual key is in an effective state, and after the fault information of the controller 2 is received, an operator can reset the controller 2 by controlling the watchdog component 3 through the virtual key in the effective state. When the heartbeat connection between the controller 2 and the display 11 is recovered to normal, the virtual key on the display 11 is recovered to an invalid status of non-clickable.
The two states of the virtual key can also be understood as a virtual key power-on state and a virtual key power-off state. When the display 11 can receive the signal of the controller 2, the virtual key is in a power-off state, and when the display 11 cannot receive the signal of the controller 2, the virtual key is in a power-on state. Even if the virtual key is operated in the power-off state, the virtual key cannot trigger the watchdog component 3 to reset the controller 2. In the power-on state, the operator can trigger the watchdog component 3 to reset the controller 2 through the virtual key.
Further, on the basis of the above embodiment, in the controller resetting device in this embodiment, the detecting component may include a signal receiver; the signal receiver is connected to the controller 2 and the switch 12, respectively, and is configured to receive the fault information of the controller 2. The switch 12 includes physical keys; the entity key is respectively connected with the signal receiver and the watchdog component 3, and the entity key is used for receiving a reset operation signal of an operator and triggering the watchdog component 3 to reset the controller 2.
Specifically, the controller 2 and the signal receiver are in communication connection, so that the signal receiver can receive the signal sent by the controller 2 in real time, and when the signal receiver receives the signal sent by the controller 2, the physical key is in a power-off state, that is, the physical key cannot trigger the watchdog component 3 to reset the controller 2. Only when the signal receiver can not receive the signal sent by the control, the entity key can be powered on, and the watchdog component 3 can be controlled through the entity key, so that the controller 2 is reset. After the reset is completed, the normal connection between the signal receiver and the controller 2 is restored, and the physical key is restored to the invalid state.
Further, on the basis of the above embodiment, the controller resetting device in this embodiment may further include an alarm component; the alarm assembly is connected with the reset assembly, and when the reset assembly detects fault information of the controller, the alarm assembly sends out an alarm prompt.
Specifically, the alarm assembly is arranged, so that an operator can know the fault information of the controller in time and make maintenance treatment in time, and the working efficiency of the working machine is improved. The specific mode of the alarm component can be a light flashing alarm, a sound alarm and the like. The specific alarm flow is that when the reset assembly detects that the controller fails, the alarm assembly is triggered to send alarm information, so that the fault processing efficiency is improved.
