Description
Technical Field
The invention relates to a control method of a vehicle, in particular to a method for controlling the sudden stop of a coke pushing rod of a coke pushing vehicle in a coking plant area.
Background
A plurality of interlocking control systems exist in the coke oven locomotive in a coking plant area during operation, and a coke pushing interlocking system of a coke pusher is the most critical safety interlocking system in coking production, which means the coordinated control of a coke pushing rod of the coke pusher, a coke guide and a coke quenching car, thereby avoiding the accidents of control failure and red coke landing and ensuring the safe and orderly coking production. The coke pushing emergency stop function in the interlocking system is a key part of the coke pushing interlocking system, and can control the coke pushing rod to stop when the red coke overflows, so that the overflow amount of the red coke is reduced to the maximum extent, the accident loss is reduced, and the personal safety of operators is ensured. However, this system has two drawbacks: firstly, the interlocking system is limited, and only the emergency stop signals sent by the coke guide and the coke quenching car which are in production can control the coke pushing rod to stop the coke pushing action; and secondly, under the condition that the coke pushing interlocking system of the coke pusher is unlocked, although the coke guide and the coke quenching car are also operated, the coke pushing emergency stop signals sent by the coke guide and the coke quenching car cannot control the coke pushing rod of the coke pusher to stop operating, so that great potential safety hazards exist.
Disclosure of Invention
The invention aims to provide an emergency stop control method for a coke pushing rod of a coke pusher during operation, so that a coke guide and a coke quenching car in a production state or a standby state can control the coke pushing rod to stop, and coke pushing emergency stop signals of the coke guide and the coke quenching car can control the coke pushing rod of the coke pusher to stop operation under the state that the coke pusher is unlocked by a coke pushing interlocking system, thereby avoiding the occurrence of red coke landing accidents and ensuring the safety of equipment and the personal safety of operators.
The originally designed coke pushing emergency stop signal is located in an interlocking coke pushing mode of a control process in the coke pushing emergency stop control system, namely a signal identification branch of the working vehicle, as shown in a control flow chart of fig. 1.
Therefore, only the coke guide car and the coke quenching car which are in operation can control the stop of the coke pushing rod, and the coke pushing emergency stop signals of the standby coke guide car and the coke quenching car cannot control the stop of the coke pushing rod; and in the unlocking mode, the coke pushing emergency stop signals of any coke guide car and coke quenching car cannot control the stop of the coke pushing rod.

the method comprises the following steps that (I) wireless communication networks are arranged on coke pushers, coke dumpers and coke quenching cars of a coking plant area, wireless communication modules on all the cars are connected with a microprocessor, the microprocessor is connected with an I/O input/output unit, and the I/O input/output unit is connected with an electrical control system on each car;
setting a coke pushing emergency stop signal of an emergency stop control system process of the coke pusher in a coke guide and coke quenching car signal judgment main loop, so that the coke pushing emergency stop signals of all vehicles can control a coke pushing rod of the coke pusher to stop;
thirdly, adding a program for judging whether the coke pusher receives a coke guide or a coke quenching car to send a coke guide quick stop instruction into a branch of the coke pusher in which the interlocking coke pushing mode unlocking of the quick stop control system process is judged to be yes, and returning to enter a coke guide or coke quenching car position judging program if the interlocking coke pushing mode unlocking of the coke pusher is judged to be yes, namely, recovering the automatic operation mode of the system to be the interlocking mode; if not, entering the coke pushing command issuing program according to the original path.
The wireless communication network can transmit a coke pushing emergency stop signal of the coke guide or the coke quenching car to the coke pusher, so that the coke pusher can independently execute a coke pushing stop instruction.
The coke pushing emergency stop signals of all the vehicles can control the coke pushing rods of the coke pusher to stop, including the coke guide or the coke quenching car which is in operation on site, and also including the coke guide or the coke quenching car which is in a standby state on site.

2, the function of controlling the coke pushing rod to stop by the coke pushing emergency stop signal in the unlocking coke pushing mode is realized, so that the control range of the coke pushing rod of the coke pusher is expanded from the original design that the interlocking mode is controllable (the unlocking mode is not controllable) to the interlocking or unlocking mode which is all controllable, a safe production mode that 'the accident can not be thought' is formed, and the possibility of the occurrence of the artificial red coke landing accident is eliminated.

Detailed Description
The method for controlling the scram of the pushing ram of the coke pusher is further described in detail with reference to the accompanying drawings.
FIG. 1 is a coke pushing interlock system control flow diagram of a coke pusher of the prior art. In the prior art, a coke pushing emergency stop signal of a coke pusher is located in an interlocking coke pushing mode, namely a working vehicle signal identification branch, of a control flow in a coke pushing emergency stop control system. Therefore, only the coke guide car and the coke quenching car which are in operation can control the stop of the coke pushing rod, and the coke pushing emergency stop signals of the standby coke guide car and the coke quenching car cannot control the stop of the coke pushing rod; and in the unlocking mode, the coke pushing emergency stop signals of any coke guide car and coke quenching car cannot control the stop of the coke pushing rod.
And FIG. 2 is a flow chart of the sharp stop control of the pushing ram of the coke pusher of the present invention. Compared with the figure 1, the method for controlling the sharp stop of the pushing ram of the coke pusher comprises the following three steps:
the first step is as follows: the coke pushing car, the coke guide car and the coke quenching car in the coking plant area are provided with wireless communication networks, the wireless communication module on each car is connected with a microprocessor, the microprocessor is connected with an I/O input/output unit, and the I/O input/output unit is connected with an electrical control system on each car. In particular, a coke pushing emergency stop operation signal of the electric control system can be transmitted to the electric control system of the coke pusher in operation through the I/O input/output unit, the microprocessor, the wireless communication module and the communication network, so that the electric control system can directly perform the electric operation of coke pushing stop, and then stop the operation of the coke pushing rod in operation. The design actually opens a 'rear door control' mode, thereby increasing a transmission channel of a coke pushing scram signal of the coke pusher. As shown in fig. 3, the solid line indicates the originally designed signal transmission path, and the dotted line indicates the newly added signal transmission path. Signals of all the vehicles in the original design are all sent to the central coordination controller, and the central coordination controller performs logic operation and then gives an instruction for allowing the pushing ram to act or stopping the pushing ram to act. But the coke pusher selects the unlocking coke pushing mode, and the instruction given by the central coordination controller is not waited for. Because the wireless communication network covering all coke oven locomotives is utilized, coke pushing emergency stop signals of the coke guide and the coke quenching car are directly transmitted to the coke pusher by crossing the central coordination controller, and a transmission channel of the coke pushing emergency stop signals is increased.
The second step is that: the coke pushing emergency stop signal of the emergency stop control system flow of the coke pusher is arranged in the main loop of the coke guide and coke quenching car signal judgment, so that the coke pushing emergency stop signals of all vehicles can control the coke pushing rods of the coke pusher to stop. The coke pushing emergency stop signals of all the vehicles can control the coke pushing rods of the coke pusher to stop, including the coke guide or the coke quenching car which is in operation on site, and also including the coke guide or the coke quenching car which is in a standby state on site. This changes the position of the coke push scram signal in the control flow. The coke pushing emergency stop signal is arranged on the coke guide and coke quenching car signal judgment main loop, so that the coke pushing emergency stop signals of all the cars can control the coke pushing rod to stop, as shown by the position a in figure 2.
The third step: adding a program for judging whether the coke pusher receives a coke guide or a coke quenching car and sends a coke guide quick stop instruction into a branch of the interlocking coke pushing mode unlocking judgment of the coke pusher quick stop control system process, if so, returning to enter a position judgment program of the coke guide or the coke quenching car, namely, recovering the automatic operation mode of the system to be the interlocking mode; if not, entering the coke pushing command issuing program according to the original path. This action directly affects the operating mode of the cart with the newly added coke push scram signal. When the coke pusher receives the coke pushing emergency stop signals sent by the coke guide and the coke quenching car, the system automatically restores the operation mode to the interlocking mode. As shown in the position b in fig. 2, the signal judging process of the system is forced to be pulled back to the interlocking operation judging process, and at this time, the pushing lever is necessarily stopped because the pushing scram signal of the interlocking operation judging path is simultaneously effective.
Compared with the prior art, the invention has the beneficial effects that:
1. the function of controlling the stop of the coke pushing rods by using the coke pushing emergency stop signal of the standby vehicle is realized, so that the control range of the coke pushing rods of the coke pusher is expanded to all coke guide cars and coke quenching cars on site, namely four coke guide cars and three coke quenching cars, from the originally designed coke guide car and coke quenching car which only participate in the site operation, and the occurrence of large and serious red coke landing accidents is avoided;
2, the function of controlling the coke pushing rod to stop by the coke pushing emergency stop signal in the unlocking coke pushing mode is realized, so that the control range of the coke pushing rod of the coke pusher is expanded from the original design that the interlocking mode is controllable (the unlocking mode is not controllable) to the interlocking or unlocking mode which is all controllable, a safe production mode that 'the accident can not be thought' is formed, and the possibility of the occurrence of the artificial red coke landing accident is eliminated.
