[Concrete mixer truck]

After receiving the concrete, the concrete mixer truck transports the concrete to the designated site. During this period, the problem of theft of the material may occur, which may cause unnecessary disputes to the construction site and the mixing station. Therefore, material anti-theft systems are usually installed on concrete mixer trucks to avoid such problems.

As shown in FIG. 2 and FIG. 3, the present invention provides a material anti-theft system for a concrete mixer truck. In the material anti-theft system, the main working principle is: when the concrete mixer truck 500 is unloaded, by monitoring whether its current position is As the target location, to determine whether the material has been stolen. That is, the material theft prevention system includes a position monitoring system 205 that monitors the current position of the concrete mixer truck 500 and a loading and unloading material monitoring system 204 that monitors the loading and unloading state of the concrete mixer truck 500. When the second controller 202 determines that the concrete mixer truck is unloading When the current position of the concrete mixer truck 500 monitored by the position monitoring system 205 is different from the target position, the material of the concrete mixer truck 500 is judged to be stolen. Wherein, the position monitoring system 205 can be a GPS device, that is, a GPS terminal can be installed on the concrete mixer truck 500 to monitor the position.

In the above technical solution, the technology of the position monitoring system 205 is relatively mature, and no further description is made here. Among them, how to judge the unloading state of the concrete mixer truck 500 becomes a key. Accordingly, the present invention provides a loading and unloading material monitoring method for a concrete mixer truck and a loading and unloading material monitoring system 204 for implementing the monitoring method, wherein the concrete mixer truck includes agitating The loading and unloading monitoring system 204 of the present invention includes a first detecting device 201 and a second controller 202 electrically connected to each other, and the loading and unloading monitoring method provided by the present invention includes a preset step, a detecting step and a determining step, in the preset step, presetting a preset value of the oil pressure in the second controller 202, the hydraulic pressure preset value being an initial oil pressure value of the hydraulic system when the concrete mixer truck 500 carries the initial amount of concrete The initial amount of concrete may be the amount of concrete after the concrete mixer truck 500 receives the discharge of the concrete mixing station 600, or may be any amount of concrete before loading and unloading, and the initial oil pressure value is the hydraulic system capable of The oil pressure value at which the mixing drum 501 equipped with the initial amount of concrete is rotated is driven. In the detecting step, the first detecting means 201 detects the real-time value of the hydraulic pressure of the hydraulic system and feeds back the real-time value of the hydraulic pressure to the second controller 202, and in the determining step, the second controller 202 real-time the oil pressure The value is compared with the preset value of the oil pressure. When the real-time value of the oil pressure is less than the preset value of the oil pressure, the second controller 202 determines that the concrete mixer truck is unloading, and when the real-time oil pressure value is greater than the preset value of the oil pressure, Then, the second controller 202 can judge that the concrete mixer truck 500 is charged.

In the technical solution, unlike the prior art, by detecting the manner in which the mixing drum is reversing or the position of the unloading operation lever, the present invention can directly know the mixing drum by detecting the hydraulic pressure value of the hydraulic system. 501 The amount of concrete inside changes. This is because the hydraulic pressure of the hydraulic system is proportional to the amount of concrete in the mixing drum 501, that is, when the oil pressure remains unchanged, it means that the amount of concrete does not change, and it can be judged that the concrete mixer truck has not discharged or charged. . When the oil pressure is continuously reduced, it means that it is judged that the concrete in the mixing drum 501 is getting less and less, and it can be judged that the concrete mixer truck 500 is unloaded. On the contrary, it can be judged that the concrete mixer truck 500 is charged.

It should be noted that in the material anti-theft system provided by the present invention, only the unloading monitoring portion in the loading and unloading monitoring system provided by the present invention described above can be used, and the charging portion can be used for the concrete mixing station 600 described above. In the discharge control system for discharging the concrete mixer truck 500, it is possible to know the state of the concrete mixer truck during the charging process. The details are described below.

Among them, in order to make the detection more convenient, preferably, the first detecting means 201 detects the real-time value of the hydraulic pressure output from the hydraulic pump in the hydraulic system. That is, the first detecting means 201 may be a pressure sensor mounted on the pressure control valve of the hydraulic pump. Of course, other means of detecting the hydraulic pressure of the hydraulic system as will occur to those skilled in the art are also within the scope of the present invention. For example, the pressure sensor can be mounted on a hydraulic motor that drives the mixing drum 501 to rotate or other parts of the hydraulic system, and such changes should also fall within the scope of the present invention.

In addition, in the material anti-theft system, in order to make maximum use of the concrete mixer truck, the above-mentioned oil pressure preset value includes a first oil pressure preset value, and the first oil pressure preset value is a hydraulic pressure when the concrete mixer truck 500 is fully loaded. The oil pressure value of the system. That is, when the real-time oil pressure value is less than the preset value of the first oil pressure, it can be judged that the concrete mixer truck 500 is unloaded. In the discharge control system, when the real-time oil pressure value is equal to the preset value of the first oil pressure, it can be judged that the concrete mixer truck 500 is filled, and the concrete mixing station can be controlled to stop discharging, thereby avoiding material overflow. waste.

For the material anti-theft system provided by the present invention, the accuracy of the material anti-theft effect and the relationship and interests of the work site, if the occurrence of false positives has a great impact on the user. In this regard, it should be noted that during the transportation process, the concrete mixer truck 500 sometimes has a sudden accident such as a bad car. At this time, it is necessary to urgently discharge all the concrete in the mixing drum 501 to prevent the concrete from being mixed in the mixing drum 501. Solidified inside. At this time, unloading will also occur at the non-target location. If the unloading is judged to be stolen, the false alarm will be caused. If the driver is evaluated accordingly, the driver will be unfairly evaluated.

Therefore, in order to avoid this, the preset value of the oil pressure in the second controller 202 further includes a second hydraulic pressure preset value, and the second hydraulic pressure preset value is a hydraulic system when the concrete mixer truck 500 is unloaded. The oil pressure value, that is, the oil pressure value of the hydraulic system when the mixing drum 501 is rotated when there is no concrete in the mixing drum 501. Therefore, when the real-time value of the oil pressure detected by the first detecting means is equal to the second oil pressure value, the second controller 202 determines that the material of the concrete mixer truck 500 is discharged. At this time, the material anti-theft system provided by the present invention can judge that the concrete mixer truck 500 has not been stolen, but an emergency unloading occurs. This is because when the material is stolen, all the concrete will not be unloaded and stolen. This is usually the case of emergency unloading. Therefore, the material anti-theft system provided by the invention has higher accuracy and more practicality.

In the above technical solution, the second controller 202 can be installed in the user center where the user is located, and the information detected by the first detecting device 201 can be transmitted back to the second controller of the user center by using a wireless communication method (for example, a GPRS module). 202, thereby determining whether the concrete mixer truck 500 has discharged. In order to further improve the practicability of the material anti-theft system provided by the present invention, preferably, the material anti-theft system further includes a third controller 206 electrically connected to the position monitoring system 205 and the loading and unloading monitoring system 204, respectively, and the third controller is 206 determines whether the concrete mixer truck 500 has been stolen, that is, the third controller 206 is also installed in the user center, and automatically judges according to the monitoring results of the position monitoring system 205 and the loading and unloading monitoring system 204. Preferably, the material theft prevention system may further include an alarm device 207 controlled by the third controller 206.

In the specific working process, when the loading and unloading material monitoring system 204 determines that the concrete mixer truck 500 has discharged and no material is discharged, the third controller 206 determines that the concrete mixer truck 500 is unloading. At this time, the third controller can control the alarm device 207 to perform an alarm, and upload the stolen result of the material to the server for recording as a criterion for evaluating the driver. In addition, when the loading and unloading material monitoring system 204 determines that the concrete mixer truck 500 finds the unloading material and the material is discharged, that is, when the emergency discharging occurs, as shown in FIG. 3, the third controller 206 does not need to control the alarm device 207 to alarm, but It is possible to record only to prepare the driver for further reasons. Of course, at this time, the third control 206 can also control the newspaper. The alarm device 207 alarms to cause the attention of the user in the user center, but at this time the alarm record can be canceled, and the driver is not evaluated as a material stolen record. For these arrangements, it should fall within the scope of protection of the present invention. The alarm device 207 can be a buzzer, a warning light, etc., which are well known in the art, and can also control text reminding in the display screen of the user center. Such an arrangement should fall within the scope of protection of the present invention.

In addition, in order to make the determination result more accurate, both the first oil pressure preset value and the second oil pressure preset value may be set to a range value, that is, a reasonable oil can be determined by a plurality of tests by those skilled in the art. The range of pressure values, by using the range of oil pressure values, can effectively avoid the problem of inaccurate judgment caused by abnormal oil pressure values caused by fluctuations in the hydraulic system itself.

In addition to the preferred mode of the present invention described above, if an emergency unloading occurs, the driver usually reports the situation to the user center, and at this time, it can also be combined with the judgment result of the loading and unloading monitoring system 204 as a basis for further determining whether material theft has occurred. . Therefore, the material anti-theft system provided by the invention can more accurately judge whether the concrete mixer truck 500 has been stolen, so that the concrete mixer truck using the material anti-theft system is more practical.

[Concrete mixer truck and concrete pumping equipment]

To this end, the present invention provides a matching operation method for a concrete mixer truck and a concrete pumping device, and a matching operation system for realizing the matching operation method. When the concrete mixer truck 500 and the concrete pumping device 400 are matched, that is, concrete agitation After the vehicle 500 starts to discharge the concrete to the concrete pumping equipment, it can ensure that the concrete mixer truck material can be removed in time after the material is discharged, and the concrete pumping equipment 400 stops the pumping work at the same time. This ensures that the air pumping equipment 400 is not sucked out and that the efficiency is low. Then, just replace the new concrete mixer truck 500 and the concrete pumping equipment to match.

In order to achieve this, as shown in FIG. 4 to FIG. 5, the matching operation system provided by the present invention includes a discharge monitoring system 302, wherein the matching operation method provided by the present invention includes a discharging step and a moving step, In the unloading step, the concrete mixer truck 500 discharges the concrete mixing device 400, and uses the discharge monitoring system 302 to monitor whether the material of the concrete mixer truck is unloaded; in the shifting step, when the unloading monitoring system 302 determines the concrete mixer truck After the material is unloaded, the driver is notified to remove the concrete mixer truck 500 in time.

It is to be noted that there are many embodiments that can accomplish the above-described technical solutions, and only four of the preferred embodiments are described herein.

Specifically, the first detecting device 201 detects the real-time oil pressure value of the hydraulic system and feeds back the second controller 202, and the second controller 202 is pre-set with a second hydraulic pressure preset value, and the second hydraulic pressure preset value. For the hydraulic pressure value of the hydraulic system when the concrete mixer truck 500 is idling, when the real-time oil pressure value is equal to the second oil pressure value, the second controller 202 determines that the material of the concrete mixer truck 500 is discharged.
