Background
At present, in the garbage disposal equipment in the domestic market, the load capacity of the movable garbage compression equipment is mainly judged by three methods: one method is determined by depending on experience of field operators, the operation method has higher requirement on experience skills of the operators (estimating the full load state in advance can cause the loading of garbage to be stopped when the loading capacity of the garbage in the box is too small, so that the garbage can be loaded only by N boxes originally, but actually can be loaded by N + K boxes, the transportation frequency and the transportation cost of the hook arm vehicle are increased, the working time is prolonged, the integral operation cost is too high, estimating the full load state later can cause the loading capacity of the garbage in the box to be too large and the garbage can not be normally compressed, the garbage in a loading hopper can not be completely compressed, the garbage which can not be loaded can be manually cleaned, the structure part of a compression box can be damaged due to frequent high-strength compression, and the equipment can not be normally used), moreover, the conditions of each operator are different, and the experience is difficult to standardize, so the method causes the use conditions of different users to be greatly different; the second is that the feeding times of the feeding device and the times of compressing the garbage by the compression head are adopted for judgment, and the final loading capacity is difficult to accurately judge only by the times because the amount of the garbage fed each time is uncertain; the third is that the working pressure of the compression head is adopted for judgment, when the pressure value reaches a certain preset value when the compression head is pushed out every time, the compression box is judged to be filled, but the system pressure of the hydraulic system has accidental peak fluctuation when the hydraulic system works every time, and false alarm and other phenomena are often caused due to the phenomena of 'garbage clamping' and the like. From the analysis of the actual use condition of the market, the loading capacity information obtained by the three methods and the actual loading capacity have larger access, and the real-time loading capacity of the equipment at different operation stages cannot be judged, so that the phenomena of low working efficiency, overhigh operation cost, poor human-computer efficiency, equipment damage and the like are caused finally. Therefore, the alarm device can give an alarm whether the equipment is accurately fully loaded, and plays an extremely important role in the operation of the equipment, the use of operators and the service life of products.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 2 to 4, the load display system of the mobile garbage compression equipment comprises a compression executing mechanism, a hydraulic control module 7, an electric control module 8 and a full-box alarm device. The movable garbage compression equipment is mainly divided into three main modules, namely a mechanical module, an electrical module and a hydraulic module, wherein the mechanical module provides an equipment main body framework and each moving part, the electrical module provides equipment action logic control and information acquisition display, and the hydraulic module provides equipment power drive. The main working mode of the equipment is that garbage is poured into a tipping bucket 3 of the equipment, then the tipping bucket 3 rises, the garbage in the tipping bucket 3 is poured into a discharging bin 1 of the equipment, after the garbage is completely poured, a horizontal compression head 4 in a compression box 2 is repeatedly pushed out and retracted, and the garbage in the compression box 2 is compressed to a certain density, so that the aims of increasing the loading quality as much as possible in a certain volume, further increasing the loading capacity and reducing the garbage transportation cost and the operation cost are fulfilled.
The compression actuating mechanism comprises a compression head 4 and a compression head oil cylinder 5 connected with the compression head 4. The hydraulic control module 7 comprises an oil line oil pipe connected with the compression head oil cylinder 5, a hydraulic oil pump arranged on the oil line oil pipe, and a pressure sensor 71 for detecting hydraulic pressure in real time. The electric control module 8 comprises a central processing unit 81 connected with the hydraulic control module 7 and a human-computer interaction interface 82 connected with the central processing unit 81. The full box alarm device is connected with the central processing unit 81 and used for prompting the staff that the compression box 2 is full.
The load capacity display system of the mobile garbage compression equipment mainly adopts hardware such as the pressure sensor 71, the central processing unit 81, the human-computer interaction interface 82, the acousto-optic alarm device and the like to acquire, analyze and feed back information of the operation of the equipment. When the equipment compresses garbage, the pressure sensor 71 is used for acquiring the pressure change condition of the hydraulic system when the compression head extrudes the garbage; the central processing unit 81 is used for controlling the movement of the compression head, comprehensively analyzing the information acquired in the movement process of the compression head, and feeding back the result to be executed through a corresponding logical operation program; the human-computer interaction interface 82 is used for setting various operation parameters of the equipment and displaying various information in the operation of the equipment, so that an operator can intuitively know the operation state of the equipment; the audible and visual alarm is used for reminding workers that the compression box 2 is full and forbidding dumping of garbage to the discharge bin 1.
The human-machine interface 82 is used for setting parameters and displaying the remaining loading capacity of the garbage compression equipment. The setting parameters of the human-computer interaction interface 82 comprise a pressure value P1 of the compression head retracting to the right position, a pressure value P2 of the compression head extending to the right position, time T2 of the compression head retracting to the right position when the residual loading capacity is 75%, time T3 of the compression head retracting to the right position when the residual loading capacity is 50%, time T4 of the compression head retracting to the right position when the residual loading capacity is 25%, and time T5 of the compression head retracting to the right position when the box is full.
The central processing unit 81 includes a parameter storage unit, a timing unit, a pressure data comparison unit, and a first time data comparison unit. For each automatic compression of the mobile garbage compression device, the pressure sensor 71 collects the driving pressure during the operation of the compression head and provides the information to the cpu 81. Meanwhile, when the central processor 81 controls the movement of the compression head, the action time of the compression head each time is recorded and stored.
The parameter storage unit is used for storing the setting parameters of the human-computer interaction interface 82.
The timing unit is used for recording the time t1 required by the compression head 4 to be pushed out from the compression head retraction position to the compression head extension position and the time t2 required by the compression head retraction position to the compression head retraction position in each compression cycle. According to a hydraulic formula, the speed of an oil cylinder = flow/effective area of the oil cylinder, the flow = power of a motor × 612/pressure, the thrust of the oil cylinder = pressure × effective area of the oil cylinder, the volume of the oil cylinder = speed of the oil cylinder × action time, and the volume of the oil cylinder = stroke of the oil cylinder × effective area of the oil cylinder, so that the length of each pushing of a compression head is gradually reduced along with the increase of the quantity of garbage in a compression box, namely the stretching of the oil cylinder is gradually reduced, the effective area of the oil cylinder is fixed and unchanged, and the action time t1 of the oil cylinder is also gradually reduced; and along with the increase of the garbage amount, the thrust F required by the oil cylinder to stretch out every time is increased, the pressure p is also increased, the power of the motor is fixed, the hydraulic flow Q is reduced, the speed V of the oil cylinder is also reduced, the speed is reduced according to the relation among displacement, speed and time, and the required time t2 is prolonged. According to the analysis of t1 and t2, t1 is decreased with the increase of the amount of garbage in the compression box, and t2 is increased with the increase of the amount of garbage in the compression box.
The pressure data comparing unit is configured to compare the real-time pressure P detected by the pressure sensor 71 with the pressure value P2 during the extension of the compression head 4 to determine whether the compression head extension action of the compression head 4 is completed, and compare the real-time pressure P detected by the pressure sensor 71 with the pressure value P1 during the retraction of the compression head 4 to determine whether the compression head retraction action of the compression head 4 is completed. The position of the compression head retracted in place, the position of the compression head pushed out in place and the action time of the compression head can be judged by the central processing unit 81: when the compression head retracts, acquiring a pressure P, continuously comparing the pressure P with a pressure value P1 of 'the compression head retracts to the right', and judging that the compression head retracts to the right when the difference value between P and P1 is within a set threshold range; when the compression head is pushed out, a pressure P is obtained, the processor continuously compares the pressure P with a pressure value P2 of 'the compression head is pushed out in place', and when the difference value between P and P2 is within a set threshold value range, the compression head is judged to be pushed out in place at the moment.
The first time data comparison unit is used for comparing the time T2 recorded by the timing unit with the time T2, the time T3, the time T4 and the time T5 after the compression head retracts to the place to complete each time so as to determine the residual loading capacity of the garbage compression equipment and determine whether the garbage compression equipment is full. The operation time when the four states of the garbage loading capacity in the compression box is more than 25%, more than 50% and more than 75% and the box is full is determined respectively through a large number of experiments or actual data (the displayable loading capacity percentage can be increased and decreased according to the requirements of a user). When the movable garbage compression equipment compresses garbage, the whole compression mechanism is hidden inside the equipment, and an operator cannot observe the load capacity of the garbage in the compression box, so that the real-time load capacity of the equipment can be intuitively fed back to the operator through the set of logical operation, so that the operator can actively determine the load capacity, the operation mode and the like of the equipment according to actual conditions, the communication performance with auxiliary equipment is enhanced, if the garbage load capacity reaches a certain value according to the transportation time of a matched hooking arm vehicle, the garbage compression equipment can be in contact with the hooking arm vehicle in advance, the situation that the hooking arm vehicle needs to wait for the completion of the work of the compression equipment when the hooking arm vehicle arrives in advance or the situation that the hooking arm vehicle needs to wait for the arrival of the hooking arm when the garbage load reaches a certain value after delay is avoided, and the working efficiency and the man-machine effect of the equipment are improved.
The collected parameters can be logically operated by the central processing unit 81. Collecting time T2 used in the process of retracting the compression head to the right position, continuously comparing and analyzing T2 with T2, T3, T4 and T5 in the operation process of the equipment, and when T3 is greater than T2 and is not less than T2, judging that the loading capacity is more than 25% and less than 50%, namely the available loading capacity is less than 75%; when T4> T2 ≧ T3, it can be judged that the loading amount is 50% or more and 75% or less, that is, the usable loading amount is less than 50%; when T5> T2 ≧ T4, it can be determined that the loading amount is 75% or more and 100% or less, that is, the usable loading amount is less than 25%; when T2 ≧ T5, it can be determined that the inside of the compression box is full. The central processing unit transmits the operation result to the man-machine text display through Ethernet communication, so that an operator can intuitively and conveniently know the running state of the equipment. Meanwhile, because the external influence factors of the equipment in different areas are different, such as the influence of the temperature in the south and north on the hydraulic speed and the like, the related set parameters can be changed along with the change of the external influence factors, so that the equipment can be conveniently debugged, the related parameters can be set on the human-computer interaction interface 82, and debugging personnel can complete debugging without changing programs.
The setting parameters of the human-computer interface 82 further include time T1 when the garbage compression device is full, and the central processor 81 further includes a second time data comparison unit for comparing time T1 recorded by the timing unit with the time T1 after each time of the compression head reaching action is completed, so as to determine whether the garbage compression device is full. This application has effectively ensured the accuracy that full case was reported to the police through dual judgement mechanism. After the system calculates out full case information, central processing unit can be through the ethernet communication, sends alarm information to man-machine text display and integrative alarm device of reputation, can carry out the word suggestion this moment on the display screen, and the reputation alarm can produce the voice prompt of high pitch shell and turn the light suggestion of bright formula simultaneously to operating personnel grasps alarm information fast.
The central processor 81 further comprises a loop count counting unit for counting the number of times of execution of the compression actuator and assisting the timing unit to record the time t1 and the time t2 of the corresponding loop.
The central processing unit 81 further includes a fault detection unit, wherein the fault detection unit is configured to compare the time t1 of the current cycle with the time t1 of the previous cycle, and determine that the compression head 4 is stuck if a difference between the times t1 of the two cycles exceeds a set threshold. In the actual use process of the movable garbage compression equipment, due to the particularity of working properties (garbage), the compression medium is complex, and the compression head is clamped by the garbage when being frequently found at a certain position in the process of reciprocating and compressing the garbage, so that the system mistakenly thinks that the garbage loading capacity reaches the position, and the information acquisition of an electric system is inaccurate. In order to reduce the phenomenon, the fault detection unit is additionally arranged, when the system monitors that the compression head is blocked (the pressure is suddenly increased), the system can compare the time of the action of the compression head with the time of the action of the last time, when the time difference of two times is large, the system can judge that the compression head is blocked instead of garbage reaches the preset value compression density, the central processing unit automatically retracts the compression head at the moment, and the garbage at the blocked position is smoothly cleaned by the fault clearing action.
The application discloses portable rubbish compression equipment operation in-process rubbish load capacity intelligence display system in the rubbish compression case, through this set of system, can be through the motion situation of compression head of compression equipment and the signal acquisition of automatically controlled procedure, analysis, come to judge and show the load capacity in the compression case, so that the user can master in real time the load capacity of rubbish in the use, the experience skill requirement to operating personnel has been reduced, avoided leading to the in-box rubbish load capacity too little just stop the operation cost that leads to too high because of operating personnel judges the error, or the in-box rubbish load capacity too big can not accomplish the unable normal use of equipment or the equipment damage that leads to with rubbish normal compression. The invention judges the real-time loading capacity in the compression box through the logical relation of the pushing-out time, the retracting time and the action pressure of the compression head, so that the equipment operator can control the loading capacity of the compression equipment by self, and the convenience and the man-machine effect of the equipment use are improved.
As shown in FIG. 1, a method for controlling the display of the loading capacity of a mobile garbage compression device comprises the following steps
S01 sets a pressure value P1 of the compression head retracting to the right position, a pressure value P2 of the compression head extending to the right position, a time T2 of the compression head retracting to the right position when the residual load is 75%, a time T3 of the compression head retracting to the right position when the residual load is 50%, a time T4 of the compression head retracting to the right position when the residual load is 25%, a time T5 of the compression head retracting to the right position when the box is full, and a time T1 of the compression head extending to the right position when the box is full through the human-computer interface 82.
S02 the CPU 81 controls the compression head 4 to extend until the real time pressure P detected by the pressure sensor 71 is the same as the pressure value P2 to complete the extension and positioning of the compression head, records the time T1 required for the compression head 4 to be pushed out from the position where the compression head is retracted to the position where the compression head is extended to the position, compares the time T1 with the time T1, determines that the garbage compression device is full when the time T1 is less than or equal to the time T1, otherwise determines that the garbage compression device is not full.
In S02, when the real-time pressure P detected by the pressure sensor 71 is suddenly changed to a pressure value P2, and the difference between the time t1 of the current cycle and the time t1 of the previous cycle exceeds a set threshold, it is determined that the compression head 4 is stuck. When the compression head 4 is stuck, entering a fault clearing step; the fault clearing action comprises the L01 retracting action of the compression head 4 to the point where the compression head retracts into position; the LO2 compression head 4 performs the extending action until the compression head extends to the position; the L03 compression head 4 performs a retracting action until the compression head retracts to the position, returning to the S02.
S03 the cpu 81 controls the compression head 4 to perform the retracting action until the real-time pressure P detected by the pressure sensor 71 is the same as the pressure value P1 to complete the retracting action of the compression head to the proper position, records the time T2 required for the compression head 4 to retract from the protrusion position to the retraction position of the compression head, compares the time T2 with the time T2, the time T3, the time T4 and the time T5, determines that the garbage compression device is actually full when the time T2 is greater than or equal to the time T5 and the S02 determines that the garbage compression device is full, and proceeds to the next step; when the time T2 is greater than or equal to the time T5 and the garbage compression equipment is judged to be not full in S02, the garbage compression equipment is judged to be full and the process returns to S02; and when the time T2 is less than the time T5, the garbage compression device is judged to be not full, the step returns to S02 after the residual load capacity of the garbage compression device is determined, and meanwhile, the residual load capacity of the garbage compression device is displayed through the man-machine interaction interface 82. In the S03, when the time T2 is more than or equal to T2 and less than T3, the residual loading capacity of the garbage compression equipment is less than 75 percent; when the time T2 is greater than or equal to T3 and less than T4, the residual loading of the garbage compression equipment is less than 50 percent; when the time T2 is greater than or equal to T4 and less than T5, the residual loading of the garbage compression equipment is less than 25%; when the time T2 is equal to or greater than T5, the remaining load of the garbage compacting apparatus is indicated as 0.
S04 the cpu 81 controls the compression head 4 to stop the garbage compression. S04 also includes prompting staff that the garbage compression equipment is full through a full-box alarm device.
When the movable garbage compression equipment starts to compress, the collected information is fed back to the central processing unit 81 by the signal collecting devices, and the central processing unit 81 comprehensively analyzes the information through logic operation and then sends an instruction to control the automatic action of the compression head, and can eliminate the phenomena of 'garbage clamping' of the compression box and the like.
