[0023] Example like Figures 1-2 As shown, the CVA oil filling platform remote control system provided in this embodiment includes but is not limited to a remote control device, a host computer, a controller and a CVA oil filling platform, wherein the CVA oil filling platform includes but is not limited to a vacuum pump, a heating belt and an oil temperature sensor, the remote control device is connected to the host computer via the Internet, the host computer is connected to the controller, the output end of the controller is connected to the controlled end of the vacuum pump and the controlled end of the heating belt, and the input end of the controller is connected to the output end of the oil temperature sensor. Figure 1 As shown, the CVA oil filling station provides four CVA oil filling stations, each of which is respectively equipped with the vacuum pump, heating belt and oil temperature sensor, etc., so as to centrally control the oil filling process of four different target devices.

[0024] The vacuum pump is used to fill the target device with oil after starting and to end the oil filling when stopping. The target device may be, but is not limited to, a mud pulser device belonging to the drilling industry. The vacuum pump is a conventional configuration of an existing CVA oil filling station to provide the most suitable vacuum degree for the CVA oil filling process, and may be, but is not limited to, start the vacuum pump by controlling the relay to be attracted (i.e., by closing the relay, the power supply branch of the vacuum pump is turned on, thereby achieving the purpose of starting the vacuum pump, and vice versa, the vacuum pump can be stopped).

[0025] The heating belt is used to heat the oil filling pipeline after starting and terminate the heating when stopping, wherein the oil filling pipeline refers to the hydraulic oil pipeline used to fill the target device with oil. The heating belt can achieve the purpose of uniformly heating the oil filling pipeline after starting by winding the oil filling pipeline, so as to provide the most suitable hydraulic oil temperature for the CVA oil filling process, and can also specifically but not limited to start the heating belt by controlling the relay to be attracted (that is, by the relay being attracted, the power supply branch of the heating belt is turned on, thereby achieving the purpose of starting the heating belt, and vice versa, the heating belt can be stopped).

[0026] The oil temperature sensor is used to collect the temperature of the hydraulic oil in the oil filling pipeline in real time and transmit the collected result to the controller in real time. The oil temperature sensor can be implemented by using an existing temperature sensor.

[0027] The controller is used to start / stop the vacuum pump and / or the heating belt according to the control instruction from the host computer, and upload the hydraulic oil temperature from the oil temperature sensor to the host computer in real time. Figure 1 As shown, the number of the controllers is, for example, two, so as to independently control the two CVA oil filling stations.

[0028] The host computer is used to send a first control instruction for starting / stopping the vacuum pump to the controller according to the remote start / stop control instruction from the remote control device, and between sending a second control instruction for starting the vacuum pump to the controller and sending a third control instruction for stopping the vacuum pump to the controller, send a fourth control instruction for starting / stopping the heating belt to the controller according to the hydraulic oil temperature, so as to maintain the hydraulic oil temperature within the target temperature range. Specifically, sending the fourth control instruction for starting / stopping the heating belt to the controller according to the hydraulic oil temperature includes but is not limited to the following steps: according to the hydraulic oil temperature, if it is found that the current hydraulic oil temperature is lower than the first temperature value, sending a sixth control instruction for starting the heating belt to the controller, and if it is found that the current hydraulic oil temperature is higher than the second temperature value, sending a seventh control instruction for stopping the heating belt to the controller, wherein the second temperature value is greater than the first temperature value. For example, the first temperature value is 30 degrees Celsius and the second temperature value is 40 degrees Celsius, so the target temperature range is 30 to 40 degrees Celsius.

[0029] The remote control device is used to respond to user operations to generate the remote start / stop control command and transmit the remote start / stop control command to the host computer. The remote control device is an electronic device held by the user, and specifically, the remote control device can be, but is not limited to, a smart phone or a tablet computer.

[0030] Therefore, based on the aforementioned CVA oil filling platform remote control system, a new solution for realizing remote control of the CVA oil filling platform is provided, including a remote control device, a host computer, a controller and a CVA oil filling platform, wherein the CVA oil filling platform includes a vacuum pump, a heating belt and an oil temperature sensor, the remote control device is connected to the host computer through Internet communication, the host computer is connected to the controller through communication, the output end of the controller is respectively connected to the controlled end of the vacuum pump and the heating belt, and the input end of the controller is connected to the output end of the oil temperature sensor through communication, and through their collaboration, not only can the remote start and stop control of the CVA oil filling platform and the adaptive control of the hydraulic oil temperature be realized, the control efficiency can be improved, and it is conducive to meeting the temperature control requirements, but also the high and low voltage isolation design idea can be achieved, so that the control and execution of the whole system are separated, and the operation end is placed in a low voltage environment (i.e., lower than the safety voltage of 36V) through communication, thereby ensuring the safety of the operator, and facilitating practical application and promotion.

[0031] Preferably, the CVA oil filling station also includes a circulating pump, wherein the controlled end of the circulating pump is communicatively connected to the output end of the controller; the circulating pump is used to circulate the hydraulic oil in the oil filling pipeline after starting and to stop the circulation when stopping; the controller is also used to start the circulating pump between starting the vacuum pump and stopping the vacuum pump. The start of the circulating pump is used to ensure that as little air as possible is mixed in during the CVA oil filling process, and specifically, the circulating pump can be started and stopped by, but not limited to, controlling the start and stop mode of the frequency converter. In addition, the start and stop control of the circulating pump can also be achieved through the remote control device, that is, further preferably, the host computer is also used to send a fifth control instruction for starting / stopping the circulating pump to the controller according to the remote start and stop control instruction.

[0032] Preferably, the host computer is also used to send the third control instruction to the controller when the CVA oil filling station is found to be faulty. For example, if the hydraulic oil temperature is found to be too high or too low for a long time, it can be determined that the CVA oil filling station is faulty, and then the third control instruction needs to be sent to the controller to stop the vacuum pump / the heating belt and the circulating pump, etc. In this way, an emergency stop function is also provided, that is, the equipment can be stopped immediately when a system failure occurs.

[0033] Preferably, the host computer is also used to start the timer synchronously when issuing the second control instruction to the controller according to the remote timing control instruction from the remote control device, and issue the third control instruction to the controller when the timing value of the timer reaches the target setting time in the remote timing control instruction; the remote control device is also used to respond to user operations to generate the remote timing control instruction and transmit the remote timing control instruction to the host computer. In this way, it also has a timing function, that is, the time can be set according to the user's requirements, and the CVA oil filling is automatically stopped after the time is reached, and the execution of a warning reminder action can also be triggered. In addition, the target setting time can be 24 hours for example.

[0034] Preferably, the host computer is further used to send the fourth control instruction to the controller according to the remote start and stop control instruction. In this way, the start and stop control of the heating belt can also be achieved through the remote control device.

[0035] Preferably, the host computer is connected to the controller via RS485 bus communication. Thus, by adopting the RS485 bus design, the simplicity and reliability of the entire system can be ensured.

[0036] Preferably, the host computer is a computer device with a serial port screen, wherein the serial port screen is used to replace the remote control device. In this way, by making the operating software on the host computer side (i.e., the integrated touch screen control software) adopt the design of the serial port screen, it can be turned on in seconds to meet the needs of quick start and stop operations. In addition, the human-computer interaction interface of the serial port screen is exemplified by Figure 2 As shown, the whole system can be easily monitored and the vacuum pump, the heating belt and the circulating pump can be started and stopped; the human-computer interaction interface of the remote control device can also be as shown Figure 2 for remote monitoring.
