Description
The present invention relates to a server for diagnosing a spreader, a method and a module, and more particularly, to a spreader diagnosis server for determining whether a spreader is faulty or faulty based on a consumed voltage and a consumed current of the spreader, ≪ / RTI >
Generally, when dust accumulates on road surfaces such as bridges, curved roads, uphill, tunnel entrance, etc., road use environment becomes poor. In addition, if snow falls on the road surface or the road surface is frozen as described above, the smooth passage of the vehicle will be hindered. As a result, the road surface condition as described above may cause a serious accident due to obstruction of the driver's view, slipping of the vehicle, and the like.
In order to solve the above problem, a water-spraying vehicle for spraying water on the road surface to remove dust is mainly used. In addition, a method of directly spraying a snow remover such as calcium chloride on the road surface and a friction agent such as sea ice or sand to remove snow accumulated on the road surface and thawing the road surface is mainly used.
However, the method of spraying the spraying agent directly on the road surface by hand is difficult to spray on the multi-lane wide road surface, it is difficult to spray uniformly, and there is a problem accompanying traffic control and obstacles. In addition, since equipment and manpower must be moved directly to the road surface, there is a problem that it is impossible to perform a rapid operation and it is difficult to perform early diagnosis and early response.
Accordingly, in recent years, there has been used a spraying apparatus which is remotely controlled and installed on the roadside median or road side, and spraying the spraying agent onto the road surface. Such a spraying apparatus includes a power supply, a sprayer for spraying the spray agent, and a main board for applying an output voltage of the power supply to the sprayer. Here, the spreader includes an inlet portion to which the stored spread agent is supplied and a discharge portion to which the spread agent is sprayed on the road surface.
When the spray device is remotely controlled, a method of attaching a flow rate sensor to the inlet or outlet of the sprayer is used to determine whether the spray agent is actually sprayed. However, there is a problem that the flow rate sensor is corroded by the saline and sediment of the liquid spreading agent, and when the foreign matter or the like is introduced into the spreader, there is a problem that the flow rate sensor is broken. Accordingly, various methods for diagnosing the failure of the sprayer including the actual spraying of the spray agent have been proposed.
However, the conventional method of diagnosing the spreader has a problem that the cause of failure of the spreader can not be grasped by detecting only the spraying of the spraying agent using the flow rate sensor. In addition, the conventional method of diagnosing a spreader has a problem that the status of the spreader can not be grasped remotely by grasping the failure and the cause of failure of the spreader on the spot. In addition, the conventional method of diagnosing a spreader can not immediately stop the operation of the spreader even when the spreader fails, and thus there is a problem that damage to the spreader due to overload of the spreader and system failure can not be prevented. In addition, since the conventional method of diagnosing a spreader can not identify the cause of failure of the spreader based on the residual application amount, there is a problem that failure of the spreader due to idling of the spreader can not be prevented.
The present invention aims to provide a spreader diagnosis server, a method and a module which can compare a consumed voltage value and a consumed current value of a spreader with a reference voltage value and a reference current value, respectively, and determine the cause of failure of the spreader.
It is another object of the present invention to provide a spreader diagnosis server, method, and module capable of remotely determining whether a spreader is malfunctioning by determining whether a spreader is malfunctioning and transmitting a determination result to a user terminal.
Another object of the present invention is to provide a spreader diagnosis server, method and module capable of preventing the spreader from being damaged due to overload of the spreader and system failure by stopping the operation of the spreader when the spreader is judged as a failure.
Another object of the present invention is to provide a spreader diagnosis server, a method and a module that can prevent the spreader from failing due to idling of the spreader by determining the cause of failure of the spreader by comparing the residual spread amount of the spreader with a reference amount.
The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention which are not mentioned can be understood by the following description and more clearly understood by the embodiments of the present invention. It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
According to an aspect of the present invention, there is provided a spreader diagnostic server comprising: a transceiver for receiving a consumed voltage value and a consumed current value of a spreader from a main board; and a controller for comparing the consumed voltage value with a reference voltage value, And a determination unit for determining whether the spreader is malfunctioning or not by comparing the current value with a reference current value, and the transceiver transmits a failure signal to the user terminal when it is determined that the spreader is malfunctioning, To the main board.
According to another aspect of the present invention, there is provided a method of diagnosing a spreader, comprising: receiving a consumed voltage value and a consumed current value of a spreader from a main board; comparing the consumed voltage value with a reference voltage value; Determining whether the spreader is malfunctioning or not and, if it is determined that the spreader is malfunctioning, transmitting a malfunction signal to the user terminal and transmitting a cutoff signal to stop the operation of the spreader to the mainboard The method comprising the steps of:
Also, the spreader diagnostic module according to an embodiment of the present invention may include a measuring unit for measuring a consumed voltage value and a consumed current value of a spreader, and a comparing unit for comparing the consumed voltage value with a reference voltage value and comparing the consumed current value with a reference current value And a diagnostic unit for diagnosing whether the spreader is faulty or faulty, and the diagnosis unit transmits a fault signal to the user terminal when the diagnosis unit determines that the spreader is faulty, To the board.
As described above, according to the present invention, the consumed voltage value and the consumed current value of the spreader are compared with the reference voltage value and the reference current value, respectively, so that the cause of failure of the spreader can be grasped.
In addition, according to the present invention, it is possible to remotely determine whether the spreader is malfunctioning by determining whether the spreader is malfunctioning and transmitting the determination result to the user terminal.
In addition, according to the present invention, when the spreader is judged to have a failure, the operation of the spreader is interrupted, thereby preventing breakage of the spreader due to overload of the spreader and system failure.
In addition, according to the present invention, it is possible to prevent breakdown of the spreader due to idling of the spreader by comparing the residual spread amount of the spreader with the reference amount to determine the cause of the breakdown of the spreader.
