Problems solved by technology

[0002] With the development of economy and society, FMCG manufacturers widely use remote positioning modules to manage commercial cold chain equipment based on the willingness to supervise the safety of commercial cold chain equipment. However, the existing remote positioning module has a single analog-to-digital conversion interface and cannot simultaneously satisfy multiple channels. , Various types of detection requirements, therefore, it is necessary to expand the remote positioning module one analog-to-digital conversion interface to a multi-channel analog-to-digital conversion interface to enhance the practicability of the remote positioning module

Embodiment 1

[0026] Such as figure 1 The shown remote positioning module expands the analog-to-digital conversion channel device, including an analog-to-digital channel selection chip, a remote positioning module and a power module, and the data communication interface of the analog-to-digital channel selection chip is connected to the analog-to-digital conversion interface of the remote positioning module through a line , the control input ends of the modulus channel selection chip are respectively connected to the input / output ends of the remote positioning module through lines;

[0027] The modulus channel selection chip is configured to read the value of the register of its corresponding data communication interface according to the address code sent by the remote positioning module, and then send it to the remote positioning module;

[0028] The remote positioning module is configured to send an address code to the modulus channel selection chip, and then process the return value of t...

Embodiment 2

[0036] On the basis of the above embodiments, the present invention provides a method for extending the analog-to-digital conversion channel of the remote positioning module, wherein the steps are as follows:

[0037] Step 1: After the system is running, the remote positioning module sends an address code to the SP8T switch chip;

[0038] Step 2: The SP8T switch chip reads the value of the register of the corresponding data communication interface according to the address code sent by the remote positioning module, and returns the value to the remote positioning module;

[0039] Step 3: Change the address code;

[0040] Step 4: Repeat steps 1-3 until the remote positioning module polls the eight-way data communication interface of the single-pole eight-throw switch chip, and then eight pieces of data can be obtained;

[0041] Step 5: The remote positioning module writes the obtained eight pieces of data in turn into its internal storage manager or EEPROM memory chip for stora...

Abstract

The invention discloses a device and a method for expanding an analog-digital conversion channel of a remote positioning module, and belongs to the field of remote positioning modules. The device comprises an analog-digital channel selection module, a remote positioning module, and a power module. The data communication interface of the analog-digital channel selection module is connected with the analog-digital conversion interface of the remote positioning module through a circuit. The control input end of the analog-digital channel selection module is connected with the input / output end of the remote positioning module through a circuit. Through adding an analog-digital channel selection module, the analog-digital conversion channel of the remote positioning module is increased to multi-channel. The newly added data sampling interface of the remote positioning module can be widely applied in acquisition of temperature, humidity, voltage and other data, and through a remote data transmission function, acquired data can be transmitted in a classified manner to a background server to store and display. The device is low in cost, high in reliability, and wide in application range, and solves a problem of signal data acquisition of an existing remote positioning module.
