Therefore, the application provides an emergency stop control system of a rotary drilling rig, the transmission of a judgment signal is realized between a main controller and a remote control receiver in a wired mode and a wireless mode, namely the judgment signal is transmitted in the wired mode and the wireless mode, when a transmission rule of the remote control receiver and the main controller when the remote control receiver mutually transmit signals does not correspond to a preset rule in the working process of the remote control rotary drilling rig, the signal transmission between the main controller and the remote control receiver is abnormal, therefore, the main controller or the remote control receiver generates an emergency stop signal, an emergency stop control circuit is conducted under the action of the emergency stop signal, the emergency stop signal is transmitted to an engine controller, the engine controller controls the rotary drilling rig to stop working according to the emergency stop signal, namely, in the emergency stop process of the remote control rotary drilling rig, the main controller and the remote control receiver both participate in the completion of the emergency stop function of the remote control rotary drilling rig, when the remote control receiver or the main controller breaks down, the remote emergency stop can still be realized.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic diagram of an emergency stop control system of a rotary drilling rig according to the present application, and as shown in fig. 1, the emergency stop control system of the rotary drilling rig includes a remote control transmitter 5, a remote control emergency stop switch K2, an engine controller 1, a main controller 2, a remote control receiver 3, and an emergency stop control circuit 4.
Wherein the engine controller 1 comprises an emergency stop signal input; one end of the emergency stop control circuit 4 is electrically connected with the main controller 2 and the remote control receiver 3 respectively, and the other end of the emergency stop control circuit 4 is electrically connected with the emergency stop signal input end.
The remote control transmitter 5 is connected with the remote control receiver 3 through wireless communication, the remote control emergency stop switch K2 is connected with the input end of the remote control transmitter 5, and the other end of the remote control emergency stop switch K2 is connected with a remote control 24V power supply.
The main controller 2 is electrically connected with the remote control receiver 3, so that the main controller 2 and the remote control receiver 3 mutually transmit the judgment signals in a wired transmission mode. Specifically, as shown in fig. 1, the main controller 2 includes a first determination signal input end, a first determination signal output end, and a power supply end, wherein the power supply end is connected with a 24V power supply of the rotary drilling rig; the remote control receiver 3 comprises a second judgment signal input end, a second judgment signal output end and a power supply end, wherein the power supply end is connected with a 24V power supply of the rotary drilling rig; the first judgment signal output end of the main controller 2 is electrically connected with the second judgment signal input end of the remote control receiver 3, and the second judgment signal input end of the main controller 2 is electrically connected with the second judgment signal output end of the remote control receiver 3, so that the main controller 2 and the remote control receiver 3 are electrically connected.
The main controller 2 and the remote control receiver 3 are also connected through wireless communication, so that the main controller 2 and the remote control receiver 3 can transmit the judgment signal mutually in a wireless transmission mode. Namely, the first judgment signal generated by the main controller 2 can be divided into a first wired judgment signal and a second wireless judgment signal, and the second judgment signal generated by the remote control receiver 3 can be divided into a second wired judgment signal and a second wireless judgment signal, wherein the first wired judgment signal and the second wired judgment signal can be mutually transmitted through the electric connection between the main controller 2 and the remote control receiver 3; the first wireless judgment signal and the second wireless judgment signal can be transmitted to each other through the wireless communication connection between the main controller 2 and the remote control receiver 3.
When the judgment signal transmission rule between the remote control receiver 3 and the main controller 2 does not correspond to the preset transmission rule, the remote control receiver 3 or the main controller 2 generates an emergency stop signal; that is, an abnormality occurs in the transmission of the determination signal between the remote control receiver 3 and the main controller 2, the remote control receiver 3 or the main controller 2 generates an emergency stop signal. The emergency stop control circuit 4 is conducted under the action of the emergency stop signal, so that the emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop working, namely the rotary drilling rig stops.
When the transmission rule of the judgment signal between the remote control receiver 3 and the main controller 2 corresponds to the preset transmission rule, it is indicated that the remote control receiver 3 and the main controller 2 of the rotary drilling rig both work normally, and it is only required that the judgment signal mutually transmitted by the main controller 2 and the remote control receiver 3 determines whether the rotary drilling rig needs to be stopped, for example, when the main controller 2 and the remote control receiver 3 both work normally, when the judgment signal mutually transmitted by the main controller 2 and the remote control receiver 3 is at a low level, it is indicated that the rotary drilling rig needs to be normally scrammed, then the scram control circuit 4 is turned on according to the judgment signal, so that the scram signal is transmitted to the engine controller 1, so that the engine controller 1 controls the engine to stop working, namely, the rotary drilling rig stops. When the judgment signal mutually transmitted by the main controller 2 and the remote control receiver 3 is high level, it indicates that the rotary drilling rig does not need normal emergency stop, and therefore the stop control circuit is disconnected, and the rotary drilling rig continues to work normally.
According to the emergency stop control system of the rotary drilling rig, the main controller 2 and the remote control receiver 3 realize the transmission of the judgment signal in a wired mode and a wireless mode, namely the judgment signal is transmitted in the wired mode and the wireless mode, when the transmission rule of the remote control receiver 3 and the main controller 2 in the mutual signal transmission process does not correspond to the preset rule in the working process of the remote control rotary drilling rig, the abnormity of the signal transmission between the main controller 2 and the remote control receiver 3 is explained, therefore, the main controller 2 or the remote control receiver 3 generates the emergency stop signal, the emergency stop control circuit 4 is conducted under the action of the emergency stop signal, so that the emergency stop signal is transmitted to the engine controller 1, the engine controller 1 controls the rotary drilling rig to stop working according to the emergency stop signal, namely, in the emergency stop process of the remote control rotary drilling rig, the main controller and the remote control receiver both participate in the completion of the emergency stop function of the remote control rotary drilling rig, when the remote control receiver or the main controller breaks down, the remote emergency stop can still be realized.
Specifically, the wireless communication connection between the main controller 2 and the remote control receiver 3 may be: the main controller is connected with the remote control receiver 3 through a CAN bus so as to realize wireless communication connection between the main controller 2 and the remote control receiver 3.
Specifically, the signal transmission rule between the remote control receiver 3 and the main controller 2 does not correspond to the preset transmission rule, and the generation of the emergency stop signal by the remote control receiver 3 or the main controller 2 may include the following 6 cases:
(1) when the preset transmission rule comprises: when the wired signal and the wireless signal transmitted between the remote control receiver 3 and the main controller 2 correspond to each other, then when the remote control receiver 3 receives the first wired judgment signal and the first wireless judgment signal transmitted by the main controller and do not correspond to each other, for example, the first wired judgment signal is at a high level, the first wireless judgment signal is at a low level, since the first wired judgment signal and the first wireless judgment signal are both transmitted by the first judgment signal through both wired and wireless transmission methods, the first wireless judgment signal and the first wired judgment signal should correspond to each other, therefore, when the remote control receiver 3 receives the first wired judgment signal and the first wireless judgment signal transmitted by the main controller and do not correspond to each other, it is indicated that the main controller 2 is abnormal or disconnected, so the remote control receiver 3 generates an emergency stop signal, the emergency stop control circuit 4 is turned on under the effect of the emergency stop signal, so that an emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop working, namely the rotary drilling rig stops. That is, when the master controller 2 is abnormal, the remote control receiver 3 actively generates an emergency stop signal.
(2) Similarly, when the preset transmission rule includes: when the wired signal and the wireless signal transmitted between the remote control receiver 3 and the main controller 2 correspond to each other, then when the main controller 2 receives a second wired judgment signal and a second wireless judgment signal transmitted by the remote control receiver 3, for example, the second wired judgment signal is at a high level, the second wireless judgment signal is at a low level, since the second wired judgment signal and the second wireless judgment signal are both transmitted by the wired and wireless transmission methods, the second wireless judgment signal and the second wired judgment signal should correspond to each other, therefore, when the main controller 2 receives the second wired judgment signal and the second wireless judgment signal transmitted by the remote control receiver 3, it indicates that the remote control receiver 3 is abnormal or disconnected, so the main controller 2 generates an emergency stop signal, the emergency stop control circuit 4 is turned on under the action of the emergency stop signal, so that an emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop working, namely the rotary drilling rig stops. That is, when the remote control receiver 3 is abnormal, the main controller 2 actively generates an emergency stop signal.
(3) When the preset transmission rule comprises: the packet loss rate when the remote control receiver 3 is connected with the main controller 2 through wireless communication to transmit signals is less than the preset packet loss rate; that is, when the remote control receiver 3 and the main controller 2 transmit signals wirelessly, the packet loss rate of the signals must be smaller than the preset packet loss rate. Therefore, when the first packet loss rate when the remote control receiver 3 receives the first wireless determination signal transmitted by the main controller 2 is greater than or equal to the preset packet loss rate, it indicates that the packet loss rate is greater when the main controller 2 transmits the first wireless determination signal to the remote control receiver 3, that is, the main controller 2 is abnormal in the process of transmitting the wireless signal, so that the remote control receiver 3 generates an emergency stop signal, and the emergency stop control circuit 4 is turned on under the action of the emergency stop signal, so that the emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop working, that is, the rotary drilling rig stops. That is, when an abnormality occurs in the main controller 2 during the transmission of the wireless signal, the remote control receiver 3 actively generates an emergency stop signal.
(4) When the preset transmission rule comprises: the packet loss rate when the remote control receiver 3 is connected with the main controller 2 through wireless communication to transmit signals is less than the preset packet loss rate; that is, when the remote control receiver 3 and the main controller 2 transmit signals wirelessly, the packet loss rate of the signals must be smaller than the preset packet loss rate. Therefore, when the second packet loss rate when the main controller 2 receives the second wireless determination signal transmitted by the remote control receiver 3 is greater than or equal to the preset packet loss rate, it indicates that the packet loss rate is higher when the remote control receiver 3 transmits the second wireless determination signal to the main controller 2, that is, the remote control receiver 3 is abnormal in the process of transmitting the wireless signal, so that the main controller 2 generates an emergency stop signal, and the emergency stop control circuit 4 is turned on under the action of the emergency stop signal, so that the emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop working, that is, the rotary drilling rig stops. That is, when an abnormality occurs in the remote control receiver 3 during the transmission of the wireless signal, the main controller 2 actively generates an emergency stop signal.
(5) When the preset transmission rule comprises: a first hardware fault detection result of the main controller 2 and a second hardware fault detection result of the remote control receiver 3 are both absent; that is, when both the first hardware detection result of the main controller 2 and the second hardware failure detection result of the remote control receiver 3 are absent, that is, the hardware of the main controller 2 and the hardware of the remote control receiver 3 are absent of failure.
When the main controller 2 receives that the second hardware fault detection result of the remote control receiver 3 is yes, that is, the hardware of the remote control receiver 3 has a fault, the remote control receiver 3 cannot normally operate, at this time, the main controller 2 generates an emergency stop signal, and the emergency stop control circuit 4 is turned on under the action of the emergency stop signal, so that the emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop operating, that is, the rotary drilling rig stops. I.e. when the hardware of the remote control receiver 3 fails, the main controller 2 actively generates an emergency stop signal.
(6) When the preset transmission rule comprises: a first hardware fault detection result of the main controller 2 and a second hardware fault detection result of the remote control receiver 3 are both absent; that is, when both the first hardware detection result of the main controller 2 and the second hardware failure detection result of the remote control receiver 3 are absent, that is, the hardware of the main controller 2 and the hardware of the remote control receiver 3 are absent of failure.
When the remote control receiver 3 receives a first hardware fault detection result of the main controller 2, that is, the hardware of the main controller 2 has a fault, the main controller 2 cannot normally operate, at this time, the remote control receiver 3 generates an emergency stop signal, and the emergency stop control circuit 4 is turned on under the action of the emergency stop signal, so that the emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop operating, that is, the rotary drilling rig stops. I.e. when the hardware of the main controller 2 fails, the remote control receiver 3 actively generates an emergency stop signal.

Specifically, the main engine emergency stop switch K1 may be a normally open main engine emergency stop switch K1, and when the main engine emergency stop switch K1 is the normally open main engine emergency stop switch K1, the normally open main engine emergency stop switch K1 is also turned on under the effect of the emergency stop signal, for example, when the emergency stop signal is a low level, the normally open main engine emergency stop switch K1 is closed under the low level, so that the emergency stop signal is transmitted to the engine controller 1, so that the engine controller 1 controls the engine to stop working, that is, the rotary drilling rig stops.
In addition, the main engine emergency stop switch K1 may also be a normally closed main engine emergency stop switch K1, as shown in fig. 2, when the main engine emergency stop switch K1 is a normally closed main engine emergency stop switch K1, an emergency stop signal may be transmitted to the engine controller 1, so that the engine controller 1 controls the engine to stop working, that is, the rotary drilling rig stops.

When the main controller 2 outputs an emergency stop signal, for example, when the emergency stop signal is at a low level, the coil is turned on, so that the first contact N1 and the second contact N2 are closed, so that the emergency stop signal is transmitted to the engine controller 1, and the engine controller 1 controls the engine to stop working, namely, the rotary drilling rig stops.
