As shown in the first figure, a control system (hereinafter referred to as “control system”) 100 for remotely updating control scripts includes a remote management server 1 and at least one terminal controller. In this embodiment, it includes three terminal controllers 2, 2a and 2b. Each terminal controller can be used to control at least one logic device. In this embodiment, the terminal controller 2 can be used to control five logic devices 3a-3e. Five logic devices 3a-3e can be provided in a single device or device, and one of the logic devices 3a-3e can be a general purpose input/output (GPIO) logic device, a pulse width modulation (PWM) A logic device or an analog-to-digital converter (ADC) logic device.

Please continue to refer to the second figure, which shows the internal functional block diagram of the remote management server and the terminal controller in the first embodiment of the present invention. Since the internal functions of the terminal controllers 2, 2a and 2b and the data or signal flow mode between them and the remote management server 1 are similar or the same, only the remote management server 1 and the terminal controller are listed in the second figure. The internal function block of 2 is taken as an example to illustrate.

The remote management server 1 includes a centralized management controller 11 and a storage module 12 electrically connected to the centralized management controller 11 , and the storage module 12 stores a control script lookup table 121 and two sets of initial Setting parameters (such as Group 01 initial setting parameters and Group 02 initial setting parameters) and a plurality of applicable control scripts (including control scripts AD and other control scripts not shown in Table 1 below). For example, the control script look-up table 121 can be as shown in Table 1, wherein the centralized management controller 11 can know the current control script through the control script look-up table, and can also modify the control script according to the needs of the usage situation. The control script corresponding to the identifier. Table 1: Control Script Checklist Identifier Initial setting parameters Applicable control scripts Date of last update 0001 Group 01 initial setting parameters control script A YYYY/MM/DD 0002 Group 01 initial setting parameters control script B YYYY/MM/DD 0003 Group 01 initial setting parameters control script B YYYY/MM/DD 0004 Group 02 Initial Setting Parameters control script C YYYY/MM/DD 0005 Group 02 Initial Setting Parameters control script D YYYY/MM/DD

The terminal controller 2 includes a communication interface 21 , a memory module 22 , a processing unit 23 and a basic input/output module 24 .

The communication interface 21 is used to communicate with the remote management server 1, and can be a wireless communication interface or a wired communication interface according to actual communication conditions. Specifically, when choosing to use a wireless communication interface as the communication interface 21, the communication interface 21 can be a short-range wireless communication interface (such as a Bluetooth communication interface or a WIFI communication interface) or a long-range wireless communication interface (such as a 4G communication interface or a GSM communication interface). When choosing to use a wired communication interface as the communication interface 21, the communication interface 21 can be an Ethernet communication interface, a USB communication interface, an RS232 communication interface or an RJ485 communication interface.

The memory module 22 includes a non-volatile memory (NVM) 221 and a random access memory (RAM) 222 . The non-volatile memory 221 and the random access memory 222 are electrically connected to the communication interface 21, and a unique identification code 2211 is stored in the non-volatile memory 221, which is the unique identification of the terminal controller 2 in this embodiment. The code is 0002. Preferably, the non-volatile memory 221 and the random access memory 222 can be integrally disposed in the same integrated circuit module (not shown). The processing unit 23 is electrically connected to the non-volatile memory 221 , the random access memory 222 and the basic input/output module 24 respectively, and has a built-in script execution program.

For the first time, for example, when the terminal controller 2 is initialized after leaving the factory, the remote management server 1 can determine the identification corresponding to the unique identification code 2211 after reading the unique identification code 2211 through the communication interface 21 . The code is the identification code 0002 in the control script lookup table 121 . Accordingly, the centralized management controller 11 of the remote management server 1 can retrieve the 01st group of initial setting parameters from the storage module 12 at the first time, and can stabilize the 01st group of initial setting parameters through the communication interface 21 The ground is written to the non-volatile memory 221 stored in the memory module 22 . Meanwhile, the processing unit 23 may set a set of initial basic input/output state parameters according to the 01st set of initial setting parameters. Next, the basic input/output module 24 completes an initial basic input/output setting according to the set of initial setting parameters when executing a booting procedure after the first time.

At the second time later than the first time, if a new usage situation needs to be set by the control script B after leaving the factory, the remote management server 1 can be enabled to read the terminal controller 2 through the communication interface 21 After obtaining the unique identification code 2211 , it can be determined that the identification code corresponding to the unique identification code 2211 is the identification code 0002 in the control script look-up table 121 . Accordingly, the centralized management controller 11 of the remote management server 1 can retrieve the control script B from the storage module 12 at the second time, and write and store the control script B in the memory module 22 via the communication interface 21 . the random access memory 222.

Then, the processing unit 23 can execute the script execution program 231 according to the control script B to update and set a set of script basic input/output state parameters, and transmit the set of script basic input/output state parameters back to the remote management server 1 via the communication interface The centralized management controller 11 records the control script field in the control script lookup table 121 as the control script B, and records the date when the update is completed in the last update date field. With this measure, the centralized management controller 11 can easily grasp the use and (version or type) update status of the control scripts of each terminal controller. Then, the basic input/output module 24 can update and complete a script basic input/output setting according to the set of script basic input/output state parameters when the processing unit 23 executes the script execution program 231 at the second time.

Preferably, according to different script update requirements, the processing unit 23 can update the control script B according to one of the following two update modes. If only a single temporary update is required, it is a temporary update mode. In the temporary update mode, the processing unit 23 directly reads the control script B from the random access memory 222, and executes the script execution program 231 according to the control script B. In this way, the updated control script B is only applicable to Operation after this (hard) boot. When the power is turned off next time, the basic input/output module 24 returns to complete the initial basic input/output setting according to the group of initial setting parameters (ie, the 01st group of initial setting parameters).

Conversely, if a permanent update is required, it is a permanent update mode. In the permanent update mode, the processing unit 23 reads the control script B from the random access memory 222, and stores the control script B in the non-volatile memory 221 to overwrite and replace the set of initial setting parameters. Control script B executes the script execution program. Therefore, when the power is turned off in the future, the terminal controller 2 can still continue to operate according to the updated script basic input/output settings. When establishing the control system 100, one of the above two update modes can be preset; two update modes can also be established at the same time, so that the user can select through an appropriate operation window during the update.

Preferably, once the terminal controller 2 encounters a new usage situation that needs to be matched with the control script of the usage situation, it can issue a new control script change request, which is confirmed and reviewed by the centralized management controller 11 with the unique identification code. Afterwards, the control script look-up table 121 can be rewritten, and according to the rewritten control script look-up table 121 , a new control script that meets the requirements of the usage situation is transmitted to the random access memory 222 for storage through the communication interface 21 .

Regarding the control script part, preferably, the control script may include a complex group of control commands corresponding to a plurality of (5 in this embodiment) logic devices 3a-3e, and the control commands are adjusted according to the 01st group of initial setting parameters to obtain the complex group. Corresponding to the actual input/output state parameters of the logic devices, and each set of actual input/output state parameters includes at least one of a period, an amplitude, a pulse number and a duty cycle for generating a waveform. Furthermore, the syntax of the control script is different from at least one instruction set of the processing unit 23 .

Please continue to refer to the third figure, which shows another control system for remotely updating the control script provided by the second implementation of the present invention. Based on different communication methods, preferably, in another control system 100a, compared with the control system 100, at least one communication intermediary device 4 is additionally included. The communication interface 21 can be communicatively connected to the remote management server 1 via at least one communication intermediary device 4, and the communication intermediary device 4 includes a modem, a wireless communication base station, a router, a gateway, and a repeater and at least one of a local area network server.

As mentioned above, in the control system 100 for remote update control script provided by the present invention, the terminal controller 2 is provided with the non-volatile memory 221 and the random access memory 222, and according to the needs of modification The setting data is written in stages according to the nature (such as need to modify or not to modify) and frequency (such as need to modify frequently or do not need to modify frequently).

Specifically, a group of initial setting parameters that do not need to be modified (or rarely needed) can be transmitted from the remote management server to the terminal controller at the first time when the terminal controller 2 is produced (when the terminal controller 2 has just left the factory). The device is stored in the non-volatile memory 221 of the terminal controller, so as to simplify the production management process of the terminal controller 2 .

In addition, at a second time (later than the first time) when a specific usage situation is encountered, the remote management server can transmit the control script that needs to be changed or modified according to the requirements of the usage situation to the terminal controller, and store it in a random The memory 222 is accessed, or read by the processing unit 23 and then stored in the non-volatile memory 221, so as to be modified and updated in real time according to the needs of the usage scenarios, so as to meet the control requirements of various usage scenarios. Obviously, the control system for remotely updating the control script provided by the present invention can not only achieve the effect of simplifying the production management process of the terminal controller, but also meet the needs of various usage scenarios.
