Embodiment 1

[0027] A control system and monitoring method for concrete automatic discharging, comprising a stirring tank, a pumping hopper, an ultrasonic material level sensor and a control system. An alarm device is connected outside the control system. The ultrasonic material level sensor is used to detect the current material level value of the pumping hopper, and sends the current signal to the control system. The control system determines the change rate of the concrete material level in the pumping hopper according to the current material level value of the concrete, and according to the The rate of change of the concrete level controls the discharge rate of the mixing tank. The monitoring method steps are as follows:

[0028] Step 1: preset a predetermined time, a reference material level value and a material level range, and determine the discharge rate according to the difference between the concrete material level value and the reference material level value. The reference mat...

Abstract

The invention discloses a control system and monitoring method used for concrete automatic discharging. A concrete discharging device, a concrete receiving device, a material position detection sensorand a control system body are included. The material position detection sensor is used for detecting the current material position value of the concrete receiving device, sending a current signal tothe control system body according to a detection result and meanwhile presetting a material position range. The control system body determines the change rate of the concrete material position in theconcrete receiving device according to the current material position value of concrete and controls the discharging rate of the concrete discharging device according to the change rate of the concretematerial position. The current material position value and the material position range are judged and compared, and therefore the discharging rate of the concrete discharging device is controlled. The current material position value of the concrete receiving device is monitored in real time, the discharging rate of the concrete discharging device is controlled, the work efficiency is improved, and through automatic judgment on material position detection faults, the advantages of convenient operation and high reliability are achieved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a control system and monitoring method for automatic concrete discharging. Background technique [0002] When batching concrete, it is necessary to monitor the feeding status of the concrete mixer truck and the feeding status of the pumping equipment in real time. It is necessary to prevent the occurrence of insufficient concrete mixing due to the slow discharge speed of the concrete mixer truck, affecting the pumping efficiency or even blocking the pipe. At present, the monitoring of the discharging process of the concrete mixer truck and the feeding process of the pumping equipment is usually realized by manual monitoring, and at least two operators are required to operate. Operator A operates the pumping equipment, and operator B stands next to the hopper to observe the amount of material in the hopper of the pumping equipment to control the discharge of the discharge equ...
