The invention puts forward a boom system control method, a boom control system and a boom device. The boom system control method comprises the following steps: acquiring the actual support state data of each support leg, and determining the allowed amplitude angle range or scale length range of each boom section of a boom system at different rotation angles according to the actual support state data of each support leg; detecting the amplitude angle or scale length of each boom section; and making each boom section move within the allowed amplitude angle range or scale length range. According to the method, the allowed amplitude angle range or scale length range of each boom section is determined before the boom system moves, so that during movement of each boom section of the boom system, there is no need to calculate the center of gravity of the entire vehicle constantly, and there is only the need to judge whether the amplitude angle or scale length of each boom section of the boom is within the allowed amplitude angle range or scale length range of the boom section through comparison. The existing post-control is changed into pre-control. The safety of the device can be improved, and the risk of tipping can be reduced.

The invention discloses a retractable suspension bracket. One end of each of upper cross arms and lower cross arms is hinged with a vehicle body, the other end of each of the upper cross arms and the lower cross arms is correspondingly hinged with two ends of a supporting bracket, one end, hinged with the supporting bracket, of each lower cross arm is used for being fixedly connected with a walking mechanism and further hinged with one end of a shock absorber , the other end of the shock absorber is hinged with one end of an active arm, the other end of the active arm can be rotationally hinged with the vehicle body through a rotary driving part; amphibious equipment is transferred from land to water, the rotary driving part drives the active arm to rotate earthward for driving all of the upper cross arms and the lower cross arms to rotate upwards through the hinged shock absorber, so that the walking mechanism is upwards overturned to be lifted, when the amphibious equipment is transferred from water to land, the rotary driving part drives the active arm to rotate reversely so as to release the walking mechanism, and further make each of the upper cross arms, the shock absorber and each of the lower cross arms support the walking mechanism in a double wishbone manner. The retractable suspension bracket disclosed by the invention has the advantages of scientific and reasonable design, simple and compact structure, good shock absorption effect and good retraction effect.

A software modification ontrack maintenance and optimization method includes a first step of confirming a last modification point statement of a function which needs ontrack maintenance in an onboard software code, a second step of carrying out operations of recovering a register field and modifying a return address of a novel function after the last modification point statement of the novel function, and modifying the return address of the novel function to an address of a next statement after the last modification point statement of the function which needs ontrack maintenance, a third step of carrying out joint compilation to the new function and an original onboard software code, and a fourth step of extracting a code corresponding to the novel function after the joint compilation and injecting the code onboard to replace the function which needs ontrack maintenance. Through adoption of the software modification ontrack maintenance and optimization method, the optimization design of the ontrack maintenance of software modification is achieved, the injection amount of programs can be obviously decreased, and a risk that the injected programs are overturned by a single particle is reduced.

The invention provides a control method of a boom system, a boom control system and boom equipment. The control method comprises the following steps of: dividing the motion range of each supporting leg into a plurality of motion intervals within a motion range of each of the supporting legs, according to the combination of each of the supporting legs in different motion intervals, establishing a supporting level base, and in the supporting level base, determining an allowable motion range of the boom system under each of the supporting levels and at different revolution angles; detecting the actual supporting state of each of the supporting legs, wherein the actual supporting state comprises the actual extension length and / or the unfolding angle of each of the supporting legs; and according to the detected actual supporting state of each of the supporting legs, in the supporting level base, seeking for the supporting levels corresponding to the actual supporting states of the supporting legs, so that allowable motion ranges of the boom system in different revolution angles are determined, and according to the allowable motion range, controlling the motion of each of the boom system. According to the control method disclosed by the invention, calculating the gravity center of a complete vehicle at all times is not needed, so that the calculation amount is low, and the control error rate is low.

The invention provides a sectioned control method and system for a boom system and boom equipment. The method includes the following steps that according to the actual supporting states of all supporting legs, the movement range of the boom system is divided into a plurality of supporting sections, and the allowed movement range of each boom segment of the boom system when the boom system is located in each supporting section is determined; the rotation angle of the boom system and the angles and / or expansion lengths of the boom segments are detected; and each boom segment is controlled to move in the allowed movement range when located in each supporting section, when the boom system is rotated from one supporting section to another supporting section, whether the boom segments are within the allowed movement ranges allowed by another supporting section or not is judged according to the detected angles and / or expansion lengths of the boom segments, and accordingly rotation of the boom system is controlled. By means of the method, there is no need to calculate the center of gravity of a whole vehicle at all times, the calculation amount is small, the control error rate is low, and meanwhile the boom system is high in safety when rotating.
