Description

[0001] DESCRIPTION [0002] Servers, methods and modules for diagnosing sprinklers [

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.

At this time, the transmission / reception unit 110 can transmit a shutoff signal to stop the operation of the spreader 220 and send a failure signal indicating the failure to the user terminal 230. Where the fault signal may include a first fault signal and the first fault signal may include a fault cause that a fault in the sparger 220 has occurred due to a lack of voltage supplied to the sparger 220. [

The reference current value may include a first reference current value when the determination unit 120 determines that the spreader 220 is in failure. At this time, the determination unit 120 determines the consumed voltage value (

At this time, the transmission / reception unit 110 can transmit a shutoff signal to stop the operation of the spreader 220 and send a failure signal indicating the failure to the user terminal 230. Here, the failure signal may include a second failure signal, and the second failure signal may include a failure cause of the failure of the sprinkler 220 due to clogging of the discharge portion of the sprinkler 220 or clogging of the sprinkler 220 can do.

Figure 112016043938244-pat00042
) Can be judged as shortage.

Here, the second reference current value may be changed according to the user's need. For example, when operating the spreader 220 using the power supply, the normal operating current of the spreader is

It is possible to judge that the spreader 220 is abnormal. Also, the determination unit 120 may determine that the insertion unit of the spreader 220 is clogged with respect to the cause of the failure of the spreader 220.

At this time, the transmission / reception unit 110 can transmit a shutoff signal to stop the operation of the spreader 220 and send a failure signal indicating the failure to the user terminal 230. Where the failure signal may include a fourth failure signal and the fourth failure signal may include a failure cause that the failure of the sparger 220 has occurred due to clogging of the inlet of the sparger 220. [

Meanwhile, the reference current value may include a reference current section value. The reference current section value may be a set of all values between a specific lower limit value and a specific upper limit value, and the spatterer 220 may set the consumed current value (

Figure 112016043938244-pat00066
). ≪ / RTI > At this time, the determination unit 120 determines the consumed current value (
Figure 112016043938244-pat00067
Is out of the reference current section value, it can be determined that the spreader 220 is defective. For example, when the power supply supplying power to the sprinkler 220 supplies AC power, the consumed voltage value (
Figure 112016043938244-pat00068
) Can be constant, and the consumed current value (
Figure 112016043938244-pat00069
May vary depending on the state of the spreader 220. [ When the spreader has a failure, the consumed current value of the spreader (
Figure 112016043938244-pat00070
Is measured outside the reference current section value, the determination unit 120 may determine that the spreader 220 is defective.

Figure 112016043938244-pat00073
) Is compared with the reference voltage value and the consumed current value (
Figure 112016043938244-pat00074
Is compared with the reference current value to determine whether the distributor is faulty and the cause of the fault (S620). If it is determined that the spreader is malfunctioning, the malfunction signal is transmitted to the user terminal, and a shutoff signal for stopping the operation of the spreader is transmitted to the main board (S630).
