具体实施方式 Detailed ways
如图1所示，一种煤矿上下井物料称重及报警系统是在井口的地面与井下轨道的两条铁轨上分别安装一个称重传感器，称重传感器通过信号调理电路与控制器连接，控制器分别连接显示屏、声光报警器和提升机闭锁装置。 As shown in Figure 1, a weighing and alarm system for materials in the upper and lower shafts of a coal mine is to install a weighing sensor on the ground of the wellhead and the two rails of the underground track respectively. The weighing sensor is connected to the controller through a signal conditioning circuit to control The devices are respectively connected to the display screen, the sound and light alarm and the locking device of the hoist.
本实施例中，控制器采用单片机，使得系统具有成本低、运行可靠的特点。 In this embodiment, the controller adopts a single-chip microcomputer, so that the system has the characteristics of low cost and reliable operation.
在地面与井下轨道的两条铁轨上分别平行安装一个称重传感器，当矿车的前、后轮都通过称重传感器后，由单片机根据前、后轮通过称重传感器时的检测数据，计算出矿车所载物料的重量。 Install a weighing sensor in parallel on the two rails of the ground and underground tracks. When the front and rear wheels of the mine car pass through the weighing sensor, the single-chip microcomputer calculates The weight of the material loaded by the mining cart.
井上、井下的称重传感器通过信号调理电路与单片机连接。信号调理电路由依次连接的电压放大器、电压电流转换器、精密电阻及数模转换器构成。信号调理电路的作用是将称重传感器的压力信号放大并转换成4～20mA电流信号进行传输，并通过精密电阻与数模转换器变为单片机可接受电压信号。 The weighing sensors in the well and the well are connected with the single-chip microcomputer through the signal conditioning circuit. The signal conditioning circuit is composed of a voltage amplifier, a voltage-current converter, a precision resistor and a digital-to-analog converter connected in sequence. The function of the signal conditioning circuit is to amplify the pressure signal of the load cell and convert it into a 4-20mA current signal for transmission, and through a precision resistor and a digital-to-analog converter into a voltage signal acceptable to the microcontroller.
声光报警器、显示屏以及提升机闭锁装与单片机输出端口连接。声光报警信号与显示屏信息由单片机根据称重传感器信号通过计算结果给出。 The sound and light alarm, the display screen and the locking device of the hoist are connected with the output port of the single-chip microcomputer. The sound and light alarm signal and display screen information are given by the single-chip computer through calculation results based on the load cell signal.
工作过程：当矿车的前、后轮都通过称重传感器后，由单片机根据前、后轮通过称重传感器时的检测数据，计算出矿车所载物料的重量。当上、下井物料称重没有发生超重时，显示屏显示当时上、下井物料的重量；当上下井物料称重发生超重时，发生声光报警信号，并在显示屏上显示超重的重量及警示信息，为工作人员降低负载重量提供依据，同时启动提升机闭锁装置，禁止提升机工作。 Working process: When the front and rear wheels of the mine car pass through the load cell, the single-chip microcomputer calculates the weight of the material carried by the mine car according to the detection data when the front and rear wheels pass through the load cell. When the weighing of the materials in the upper and lower wells is not overweight, the display screen will display the weight of the materials in the upper and lower wells at that time; when the weighing of the materials in the upper and lower wells is overweight, an audible and visual alarm signal will be generated, and the overweight weight and warning will be displayed on the display screen The information provides a basis for the staff to reduce the load weight, and at the same time activates the locking device of the hoist to prohibit the hoist from working.
