[0023] The preferred embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the specification. The following description is exemplary and not a limitation of the present invention. Any other similar situations shall also fall within the protection scope of the present invention.

[0024] like Figure 1 As shown, a monitoring system for a total station 1 according to a preferred embodiment of the utility model. The total station 1 can be any form applicable to the railway system. The monitoring system includes a signal acquisition module 10, a main communication module 20, a slave communication module 30, a gating control module 50, a gating interface circuit 40, a signal sending module 60, etc. Among them, the signal acquisition module 10 is connected to the total station 1 in communication to collect monitoring data of the total station 1. The main communication module 20 is connected to the signal acquisition module 10 in communication to receive monitoring data, and the user can input a first adjustment signal for adjusting the total station 1 based on the above monitoring data. The slave communication module 30 is connected to the signal acquisition module 10 in communication to receive monitoring data, and the user can input a second adjustment signal for adjusting the total station 1 based on the above monitoring data. The gating interface circuit 40 is connected to the main communication module 20 and the slave communication module 30 in communication to receive signals. The gating control module 50 is connected to the main communication module 20 and the gating interface circuit 40 respectively, and interrupts the communication connection between the slave communication module 30 and the gating interface circuit 40 in response to the first adjustment signal. The signal sending module 60 is communicatively connected to the selection interface circuit 40 and the total station 1 respectively to transmit the first adjustment signal or the second adjustment signal to the total station 1 .

[0025] The main communication module 20 and the slave communication module 30 can store the relevant monitoring data from the total station 1. The main communication module 20 and the slave communication module 30 are respectively connected to the computing platform and the monitoring platform for communication, and the two platforms store the original monitoring data that has not been interfered with or modified. In addition, the computing platform connected to the main communication module 20 usually has a computing function, which can automatically calculate the subsequent adjustment actions required by the total station 1 based on the monitoring data and send out a first adjustment signal to monitor other data, such as the distance between another point and the reference point. The computing platform and the monitoring platform can also send out corresponding adjustment signals by manual input.

[0026] During normal operation, the total station 1 monitors the target (e.g., the rails of the railway system) and collects monitoring data such as the distance between a certain position on the rails and the reference point, and the monitoring data is then transmitted by the signal acquisition module 10 to the main communication module 20 and the slave communication module 30. The gating control module 50 controls the on-off between the slave communication module 30 and the gating interface circuit 40. When the main communication module 20 sends out a first adjustment signal, the gating control module 50 will therefore receive a variable edge extension pulse with an adjustable duration. Based on the signal, the gating control module 50 closes the signal connection between the gating interface circuit 40 and the slave communication module 30 at this time; on the contrary, when the main communication module 20 does not send out the first adjustment signal, the gating interface circuit 40 and the slave communication module 30 are in normal communication connection. At this time, the user inputs a second adjustment signal to the slave communication module 30 according to the monitoring data. The selection interface circuit 40 then transmits the first adjustment signal or the second adjustment signal given by the previous unit (the main communication module 20 or the slave communication module 30) to the total station 1 via the signal transmission module, and the total station 1 performs an adjustment action to monitor other data, such as monitoring the distance between another position of the rail and the reference point.

[0027] Optionally, the signal acquisition module 10 includes a first RS232 interface circuit, a first drive circuit 12, and a first optical coupler 13 connected in sequence, wherein the first RS232 interface circuit is connected to the total station 1 for communication. The signal transmission module 60 includes a second drive circuit 61, a second optical coupler 62, and a second RS232 interface circuit connected in sequence, wherein the second RS232 interface circuit is connected to the total station 1 for communication. Figure 2 It can be seen that, in fact, the first RS232 interface circuit and the second RS232 interface circuit are the same RS232 interface circuit 11. That is, the signal acquisition module 10 and the signal transmission module 60 share the RS232 interface circuit 11. However, it should be understood that this example is only a preferred embodiment, and the first RS232 interface circuit and the second RS232 interface circuit can also be two parallel interface circuits.

[0028] In addition, despite Figure 2 It is not shown in the figure, but the monitoring system actually includes a power storage module connected to the RS232 interface circuit. The power storage module is used as the power supply of the total station 1 and the RS232 interface circuit, and is preferably an AO4407 chip.

[0029] In addition, the monitoring system may also be provided with an alarm (not shown), wherein the alarm is communicatively connected to the signal acquisition module 10 and is configured to sound an alarm when the monitoring data exceeds a predetermined threshold.

[0030] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present invention, and these changes and modifications all fall within the protection scope of the present invention.
